PRESIDENT’S COLUMN Donnie Harp
The Heat is On Its Way Spring weather is here and it’s beginning to heat up. While this is a great time to be outdoors and enjoy the change in weather, it’s also a time to remind and prepare your employees on the hazards of heat exhaustion and heat stroke.

instituted a temporary enforcement policy (TEP) through October 2, 2015 under which it would not issue citations under the new standard if the employer was making good faith efforts to comply with the standard and as long as the employer was in compliance with either the current or former training requirements. OSHA extended this TEP for residential construction through January 8, 2016 and then extended it again through March 8, 2016. (From www.osha. gov). This new standard institutes a permit program similar to the general industry confined spaces standard (29 CFR 1910.146) but it addresses construction-specific hazards. The new standard adds five new requirements: ■■ More detailed provisions requiring coordinated activities when there are multiple employers at the worksite. This will ensure hazards are not introduced into a confined space by workers performing tasks outside the space. An example would be a generator running near the entrance of a confined space causing a buildup of carbon monoxide within the space. ■■ Requiring a competent person to evaluate the work site and identify confined spaces, including permit spaces. ■■ Requiring continuous atmospheric monitoring whenever possible.
help employers make this distinction: Construction work is not limited to new construction, but can include the repair of existing facilities or the replacement of structures and their components. For example, the replacement of one utility pole with a new, identical pole would be maintenance; however, if it were replaced with an improved pole or equipment, it would be considered construction. OSHA Letter of Interruption, November 18, 2003; see also OSHA Instruction CPL 2.100, May 5, 1995 Directorate of Compliance Programs. Another consideration in determining whether the construction standard applies is whether the hazards can be eliminated and whether forced air ventilation can render the space safe for entry. Should these conditions be met as well as several other conditions set out in 29 CFR 1926.1203(e) (1), employers may follow alternate procedures instead of the permit program. The alternate procedures are set out by 29 CFR 1926.1203(e)(2). Given that the standard applies to attics, roofers should be prepared to address the safety requirements even if they are not routinely accessing attics. OSHA inspectors may start asking employees if they have had confined space training during an inspection. Part two of the article will talk about the employer’s responsibilities under the new standard.

FRSA LEGISLATIVE COUNSEL Cam Fentriss
How Assignment of Benefits Work If you are a roofing contractor, you are most likely getting a lot of e-mails from lawyers, hail mapping companies, and other businesses that specialize in finding customers who can suddenly be in need of a new roof at the expense of their insurance company. Hmm – does that sound a little odd to you? It should and it is. This scheme is something that was used with sinkholes and mold until the insurance industry found a way to shut the abusive practices down by excluding or limiting the claims. The same thing is now happening with so-called “water restoration” companies and the attorneys and sales companies that promote this are moving aggressively into the roofing industry. For the water restoration work, the statistics are incredible. In 2014, for Citizens’ Property Insurance Company, non-weather related water damage accounted for 56 percent of claims. That is absolutely ridiculous. Here is a rough idea of how it works. A property owner has a leak and calls a plumber. The plumber fixes the leak, then refers customer to a water damage company (that will be paying the plumber a referral fee, sometimes $1,000 or more). The water damage company’s agreement for the work includes an “assignment of benefits” (or AOB) that says the customer assigns his insurance benefits to the water damage company. Once the contract with an AOB is signed, then the water damage company as good as has a license to do 10 or 20 times more work than what is needed. With the AOB, the insurance company has to answer to the water damage company, not the policyholder. If the insurance company does not pay up, then the water damage company sends it to the lawyer who taught the water damage company how to do these
contracts with an AOB. That lawyer files a lawsuit and the bills start to go up, up, up. These lawyers are very smart. They know very well that this type of work cannot last very long before the insurance industry and the government find a way to stop it. They know that the millions from water damage claims is about to dry up, so they are working very hard to migrate over to roofing work so they can drain every dime out of our industry before insurers put a stop to that too. The question for us is whether we want to stand by and watch a few roofing contractors make a lot of money for a short time before property insurers rewrite their policies to dramatically cut the funds that will be paid for a damaged roof. Until the insurers and regulators catch up, these aggressive sales forces will continue to march across our state finding “reasons” people need a new roof and greedy lawyers will be more than happy to file one lawsuit after another to pressure insurance companies to pay up. Some may be tempted to believe that insurers and regulators would never allow the same kinds of limits or exclusions for roofing work coverage as exist for less crucial work like mold. But it’s not really a matter of choice if you want to keep property insurers in Florida and you want to provide insurance that people can actually afford. As the number of claims goes up, at some point, they will have to increase the rates to cover the additional cost. They will have the statistics to show exactly why a rate increase is needed and, before the government allows enormous increases in premiums, limitations on payments for roofing work will be on the table.

creative problem solving. The judges selected three projects in each of the six categories to receive either first, second or third place S.T.A.R. Awards. Universal Roof & Contracting, Orlando was awarded first place in the Unique category for their Windermere Walkable Decks project. The project team included: ■■ Estimator: Warren Mellick ■■ Project Manager, Superintendent and Foreman: Chuck Przychocki ■■ Manufacturer: Hydro-Stop ■■ Suppliers: Pro Source, ABC Supply Company ■■ Project MVP: Chuck Przychocki The Windermere Walkable Decks project took place on a two-story residence, and involved multiple stages, starting with the removal of rows of stone railing balusters and their storage. Tile and deck demolition began one deck at a time and was rebuilt at a new pitch to prevent pooling. The new plywood deck with 2x4 framing reduced the weight load on the ceilings below. Hydro-Stop was applied to the railing posts and copper flashing, and Hydro-Stop with Barrier Guard throughout before the tile was laid. The finishing touches included fresh paint applied to new gutters and Gutter Helmet covers.

Concrete and Clay Roof Tile
Tyler Allwood, Director of Technical Services and Systems for Eagle Roofing Products
In my opinion, tile roofing is the most popular steepslope roofing product in the world. For thousands of years, tile has graced the roofs of homes, houses of worship, universities and commercial structures. In many parts of the globe it is the primary choice for roofing. Why has tile roofing remained so popular throughout the millennia? There are many reasons. Tile is beautiful, distinctive, long-lasting, strong and safe. Not only does it enhance the curb appeal of a building, it also provides protection from the most extreme weather conditions. Because it is a natural product made from some of the strongest materials, it will continue to provide that protection for a long time. For much of its history, roof tile was generally understood to be round and red, perfect for Mediterranean and old-world architecture. While tile remains ideal for an old-world look, innovations in the last 100 plus years have allowed the tile industry to create products that are perfect for any architectural style. In order to fully comprehend the benefits of roof tile, it is important to know more about the two prevailing types of roof tile, clay and concrete. There are definite
differences between clay and concrete tiles, mostly in their construction. However, both clay and concrete tile provide many of the same benefits to the building owner, namely a beautiful roof that will stand the test of time.
Clay Roof Tile
Clay roof tile is believed to have originated in China around 10,000 BC. Clay tile was also used by most early civilizations, including Greece, Ancient Rome and Egypt. As in these early times, clay roof tile is still made from earthen clay that is formed into molds and fired or baked in kilns. Clay is very dense and non-porous making it an excellent product for roofing. The production process for clay roof tile varies. Some tiles are still molded by hand and baked in brick ovens in small villages. Then there are modern companies using advanced technology to create precise interlocking tiles.
Clay tiles grace the rooftops of the buildings in Dinkelsb端hl, Bavaria, Germany.
12
FLORIDA ROOFING | March 2016
As one might expect, the production process effects the look and strength of the final product and there are different grades of clay roof tiles, culminating in Grade 1, as determined by ASTM C-1167. In addition to earthen clay, companies may use additives to enhance strength or coloring agents to expand their offering. They may also use a specialized firing process to create a harder product that can stand up to more extreme weather. As with any roofing product, it is important to consider the environment where the roof is to be installed in order to select the clay tile that meets the needs of the project. Clay roof tile is available in many profiles, sizes, shapes, colors and finishes. Often referred to as terracotta tiles, clay roof tiles have broken free of traditional red or orange pan and cover design. They are available in a multitude of variations of “S”, flat and roll profiles. Colors span the spectrum from the traditional reds to bright glazed ceramic finishes. The broad variety of these tiles is on display around the country and they are often found on university, government and historical buildings, including the Supreme Court.
Concrete Roof Tile
In the early to mid-nineteenth century a process called hydration – that occurs when aggregate, cement and water are combined, was discovered. This innovation would forever change construction throughout the world. What can be described as an early nanotechnology, due to the molecular changes that occur in cement during hydration, ushered in an incredibly strong and affordable

material with endless possibilities and uses. Shortly after the discovery of concrete, the first concrete tiles were created in Germany and over the following century improvements to the production process have led to the concrete tile roofs that are so popular today. In modern manufacturing facilities, concrete roof tiles are made by combining Portland cement, aggregate and water, as well as coloring agents and in some cases various additives. The mixture is then extruded onto molds and sent into a kiln. The extrusion process was an important innovation, as it makes concrete roof tile denser and less porous. While more porous than clay roof tile, concrete roof tile does have to pass a water absorption test, as well as a permeability test. Concrete roof tiles are available in three main profiles: high, medium and flat. High profile tiles are often called “S” or high barrel tiles and are meant to emulate a traditional pan and cover. Medium profile tiles are sometimes referred to as roll or medium barrel tiles. Flat profiles are available in many textures and finishes and are often used to emulate slate or cedar shake roofs. In addition to different profiles, there are different coloration processes available. Concrete roof tiles can be made with through-body coloring, known as color through, or with a slurry or color bonded surface coating. Color through tiles are made by combining the coloring agents with the aggregate, cement and water before extrusion and are basically the same color on the top and bottom of the tile. Slurry is a combination of the coloring agent, water, cement and a small amount of fine sand
that is applied to the surface of the tile after the extrusion process. Most often, the tile below does not have any color. Because the process for making concrete roof tile is easily automated, it is very flexible. This allows manufacturers to produce tile in any shape, texture or color quickly. The end user benefits from the value that this affords while receiving a beautiful and strong roof.
Installation
While clay and concrete tile have different constructions and production processes, the installation of the two types of tile is very similar. In fact, for basic installations, the Tile Roofing Institute (TRI) has compiled and combined the installation instructions for manufacturers of both types of tile. The Tile Roofing Institute is the association of tile manufacturers in the United States. Its role is to aid in the testing of concrete and clay tile, aid in the development of codes, publish installation manuals, train and certify installers of clay and concrete tile and advocate for clay and concrete tile manufacturers. The TRI publishes three manuals: the TRI Concrete and Clay Roof Tile Installation Manual, the FRSA-TRI Florida High Wind Tile Installation Manual, Revised 5th Edition and the TRI Cold & Snow Concrete and Clay Tile Design Criteria for Cold and Snow Regions. More information and all of the manuals are available at www.tileroofing.org. In the past each manufacturer had its own installation instructions. Often these instructions differed, making it

Tile Bone Yard – Eclectic Collection Lisa Pate, CEM, FRSA Executive Director
Over the years, FRSA has received calls from contractors looking for a rare or unusual type or brand of tile needed for a repair on an existing structure, and we’ve referred those calls to the manufacturer’s representative if the company was still in business. If not, we’d refer those calls to Penn Marshall at All Points Tile, who has a bone yard of tile available for sale to contractors. In preparing this roof tile issue of the magazine, I decided to visit Penn’s warehouse and see for myself, just what a tile bone yard looks like. So I headed out to the heart of Oviedo to take a look. On the outside of the building, there is a list of tile manufacturers brands that are available – most of which were familiar to me – but some of the manufacturing companies themselves are long gone. Names like Bender, Duntex, Gory, Lifetile, Marley and Westile. I asked Penn how he came to own a tile bone yard, as this seems like a specific niche in the roofing market. He told me that he first became involved in the roofing industry in 1979 working for a roofing contractor and did his first tile job in 1981. “I didn’t start out with a bone yard,” noted Penn, “it was something that came about after a few years of doing roof tile jobs. When I ordered roof tile for a job, let’s say I needed 37 squares, I would order 40 squares, taking into consideration breakage in transit, onsite damages and changes made on the jobsite. That way I had enough of the same tile to complete a job. If there were leftover pieces, I’d store them.” Before long, he had a collection of roof tile from various jobs and began inventorying the tile. Often, he would get calls from roofing contractors who were selling their
16
FLORIDA ROOFING | March 2016
businesses asking if he was interested in purchasing their roof tile inventory. Word spread throughout the local community that Penn was collecting roof tile and he soon received call from landlords who owned warehouse space that was vacated by tenants, asking if he wanted to purchase or remove the roof tile left behind. As a result, the bone yard was born. Penn also imports clay and concrete roof tile from four other continents, but will not purchase tile from China. He’s very experienced with clay tile and has consulted for companies all over the world who are interested in producing clay tile. He noted that producing clay roof tile requires skill and a detailed knowledge of the materials, the types of clays and sands, and specific production and drying times. One unique and rare tile that he owns is called B. Miffin Hood tile, originally made in Soddy Daisy, Tennessee. The factory burned down in 1955 and was never rebuilt. Penn keeps 3,500 squares of tile in storage, along with bird stops, end caps for hip and ridge tile and wall copings. “Often times manufacturer’s representatives don’t have a few extra pieces of tile, or don’t have discontinued tile. Most of the time, we either have or can get those tiles for the contractor,” Penn said. I asked Penn what he would like to do when and if he retires. “I have a recreational vehicle and I would love to travel throughout the United States visiting family and friends.” Sounds like the perfect ending to a unique roofing career.
Tips for Successful Use of Foam Tile Adhesives Tom Parker, TCParker and Associates
Use of polyurethane roof tile adhesives continues to grow in the Florida market based on the superior uplift values that can be obtained and the fact that penetrations to the underlayment are minimized. It is worthwhile noting that each manufacturer includes product specific instructions with each package and that these should be read and understood by all installers. Successful installation requires that product is prepared and applied per these instructions. Each manufacturer has performed uplift testing with specific amounts of adhesive applied to each tile in a specific pattern. The design calculations for a tile roof are based on the published uplift numbers, therefore it is up to the installer to ensure the foam is applied properly. Preparation: Begin with confirming that the products you choose have a Florida Product Approval or an NOA (Notice of Acceptance) via miamidade.gov/building. The Florida Product Approval or NOA number is typically listed on the package as well. Once confirmed, note that the products have a range of optimum temperature of storage and for application. Single component products typically require shaking prior to use. Two component products require calibration prior to and during application. Consult manufacturers’ instruction manual for details. Application: Each manufacturer provides detailed written instructions along with drawings detailing the exact placement of the material (paddy or bead location) and the quantity of material (paddy or bead dimensions). These may be different for different tile profiles. It is imperative that the required amount of material is placed on each tile to ensure the design uplift numbers are achieved. In some cases, the manufacturer provides the square inches of contact area required and makes recommendations to pull up a certain number of tiles to check the contact area. Ensuring good contact area is always a prudent practice. The adhesives also have a specific “open time” or time until the foam “skins over” which must be observed to ensure good adhesion. If the foam begins to cure before the tile is placed, it is unlikely to yield the designed uplift numbers. When in doubt, remove the foam and re-apply. For the single component products, temperature and humidity have more of an impact as these are cured from moisture in the air. Two component adhesives are chemically cured and are less impacted by humidity. The manufacturers provide a maximum time between application and placement of tile, typically one to four minutes. Also recognize that there are specific bead/paddy sizes and placement for field tiles, eave tiles and hip and ridge tiles. In some cases, the amounts are dramatically different for each of these locations, so be sure to consult the manufacturers specific instructions. Based on the roof pitch, other fasteners may be needed in addition to the foam, again refer to the manufacturers’
instructions. Finally, the manufacturer’s instructions, a Florida Product Approval and Miami-Dade NOA call out that each installer needs to be trained and certified by a qualified trainer. All manufacturers provide this training, and in many cases product distributors have certified trainers as well who can certify installers. Given that the Florida Product Approval or NOA indicates adhesive must be installed per the manufacturers’ instructions, all the above items need to be followed. Polyurethane foam tile adhesives are a great way to provide the homeowner the most secure roof system possible. Given the history of weather events in Florida, it makes sense to have this offering available to your customers. Keep in mind that manufacturers, TRI and FRSA’s expertise is also available to help you ensure successful installation. Tom Parker, owner of TCParker and Associates, is a Manufacturer’s Representative for Dow TILEBOND and other products. Tom worked at Dow for 33 years where he managed the spray foam business. He is trained as a chemical engineer and is a Registered Professional Engineer. More importantly, he grew up working in residential construction in the family building business.

During a high wind event roof tiles can be damaged, resulting in the underlayment being exposed to extreme uplift pressures that the now damaged roof tile had been resisting. For the adhesive set roof tile systems, this is where the similarities end. The underlayment performance qualities for an adhesive set roof tile system require the underlayment to become part of the load path. The load path of a roof system begins at the anchor point or roof deck. Each component of the roof system that shares the load is like a link in a chain that work together to resist being pulled apart by the load placed upon it, which in this case is wind uplift. The required testing of roof systems reveals the limitations of use based on uplift resistance or design pressures in compliance with the structural chapters in the building code. The underlayment product approval should provide the installation information listed with accompanying maximum design pressures. Each installation application description should include at a minimum the following information; ■■ Deck type (plywood, OSB, primed or unprimed) ■■ Anchor sheet if required (fastening pattern provided or direct to deck) ■■ Attachment method to anchor sheet or direct to deck (hot asphalt, self-adhered, cold adhesive) ■■ Approved roof tile adhesive (compatible) ■■ Maximum design pressure Remember, underlayment used in either an adhesive set or mechanically fastened roof tile system needs to meet the design pressures specific to that building.

OSHA’s Silica Regulations by the End of this Administration Richard K. Olson, President & Technical Director, Tile Roofing Institute As reported previously, the current administration is pushing their efforts to implement the new draft OSHA regulations that will cut the allowable silica Permissible Exposure Limits (PEL) in half by the end of this administration. The original implementation date was scheduled for February 16, 2016. The actual level (AL) is being set for a desired threshold as a 75 percent reduction, but has been determined to be unenforceable and not achievable. The draft regulations include language for establishing medical baselines for employees with more than four hours per day of time-weighted exposure to such activities and the need for formal respirator programs to be in place by companies that identify such exposure. These new regulations will affect all aspects of building construction since the use of silica sand is found in everything from plaster, masonry and materials that have sand as a binder that extend to most roof systems. This will change the way we plan construction practices from the curb to the driveway, walls, electrical, plumbing and roof installations. For roof practices the greater concern is the impact on fall protection. The Tile Roofing Institute (TRI) has joined efforts with the National Roofing Contractors Association (NRCA) and the other members of the Construction Industry Safety Coalition (CISC) that has 24 industry associations in collaboration to fight the pending new regulations. The efforts have included testimony before the OSHA committees and recently the Office of Management and Budget for the White House. Our emphasis in discussions has been centered on two main areas: 1. The costs associated with the proposed regulation and, 2. The increased fall hazards for roof practices. CISC as an organization has spent the last year gathering actual field data and has determined the estimated costs from OSHA are significantly lower that actual data. Here are some of the points: ■■ A Construction Industry Safety Coalition (CISC) study (03-26-15) finds OSHA underestimated the cost of the Silica Rule for Construction (Sec. 1926) by $4.5 billion per year. ■■ OSHA says $511 million annually for Construction. ■■ CISC says $5 billion annually for Construction. ■■ The CISC report estimates that about 80 percent of the cost ($3.9 billion/year) will be direct compliance expenditures by the industry such as additional equipment, labor and record-keeping costs. ■■ The remaining 20 percent of the cost ($1.05 billion/year) will come in the form of increased prices that the industry will have to pay for construction materials and building products such as concrete block, glass, roofing shingles
and more. ■■ OSHA failed to take into account these additional costs to the construction industry that will result from the proposed standard, which will then be passed down to customers in the form of higher prices. ■■ OSHA underestimates $147 million annually for General Industry and Maritime (Sec. 1910) Page 232 of the proposed rule states – The 25 industry sectors in the overall general industry and maritime sectors that OSHA identified as being potentially affected by the proposed silica standard are as follows: ■■ Asphalt Roofing Materials ■■ Concrete Products ■■ Paint and Coatings OSHA also has not taken into account life-cycle costs. On February 7, 2014, the Construction and Demolition Recycling Association stated the following: “Our nearly 300 members are part of an industry responsible for recycling hundreds of millions of tons of material, keeping it out of landfills, saving our natural resources, while providing thousands of green manufacturing jobs. Included in this material stream are large amounts of silica-containing material, especially concrete, asphalt, drywall, and asphalt shingles. However, after a careful reading of OSHA’s proposed rule, we are gravely concerned with the unachievable PEL standard proposed. In fact, we recommend that OSHA withdraw this flawed proposal and have meaningful dialogue with the construction and demolition industry on worker safety.” Our discussions on roofing safety centered on the increased exposure to fall hazards from increased trips up and down roof ladders to materials on the ground level for proper cutting. The TRI has worked since 2006 with NIOSH on identification of potential mechanical cutting methods for roofing material with no successful options available. The use of water cutting saws with hoses, wet roof surface and fall protection equipment significantly increases the danger to the roofing professional. We stressed the highly transient workforce and huge burden on small business that represents the majority of roofing contractors. With the February 16, 2016 deadline passed and more testimony coming in, there will obviously be a time extension for any formal decision. If the current administration were serious in the commitment for being in place by January we would expect a formal release by late summer. The CISC organization, we have been actively building our case to provide accurate and validated cost estimates. As testimony has developed and www.floridaroof.com | FLORIDA ROOFING

field data collected, the CISC has positioned itself to be ready for further actions if necessary if the regulations are released as written. The hope remains that further evaluation by OMB and others will allow the withholding of the regulation until further reviews and edits can be accomplished. We ask that roofing professionals use your voice and join with others in helping to relay our concerns. We encourage all of you as individuals, companies and associations to help raise the awareness against the poorly drafted regulations. At the TRI, we are happy to help pass along information via the FRSA to its members.
For more information on how to become directly involved, please feel free to contact the TRI at info@tileroofing.org. Richard K. Olson is president and technical director for the Tile Roofing Institute (TRI). The association represents industry professionals involved in the manufacturing and installation of concrete and clay tile roofs in the U.S. and Canada, working with national, state, and local building officials to develop installation techniques, codes, and standards for better roofing systems.

Safety, the “Big Picture” Bill Coombs, Safety Consultant, FRSA-SIF
When I ask companies what is the first thought that comes to mind regarding safety, the answer is usually something like Fall Protection or OSHA Citations. Although these are important areas of concern, there are so many other things that are critical to a successful safety program. Who, what, where, when, why and how are the components that we need to address. WHO: Who benefits from a strong safety program? Everyone. Workers, their families, the company, the customer and the community. Who is responsible for job site safety? According to OSHA “the Employer shall furnish to all employees a place of employment which is free from recognized hazards that have potential or are likely to cause death or serious physical harm. In addition, the employer shall comply with all occupational safety and health standards promulgated under The Williams-Steiger Occupational Safety and Health Act of 1970.” This act also states that “Each employee shall comply with occupational safety and health standards and all rules, regulations, and orders issued pursuant to this Act which are applicable to his own actions and conduct.” Ultimately, the responsibility falls on the employer to make sure that employees follow the rules and requirements. Employees that refuse to follow the instructions of the employer, and the regulations from OSHA should be retrained or their employment terminated. WHAT: What are the safety hazards that workers are exposed to? As employers, we need to look at every potential area of concern where a worker could get injured and address it before work begins. What do you need to do? List all hazards, fall issues, Personal Protection Equipment (PPE), chemicals, electrical, ladders, burns, weather, etc. and review your records to make sure that all workers have been properly trained to do the job safely. If there is a void in your training it needs to be addressed before workers start the job, not after someone gets injured. It is not enough to hand a worker a bucket and say, “here’s your fall protection,” you must stress to them the importance as well as train them on the proper use of the equipment and when it is required. 20
FLORIDA ROOFING | March 2016
WHERE: Where are workers exposed to hazards? Take a good look at your entire operation, evaluate your program and determine if you have any “holes” that need fixing. Workers can be exposed to hazards in the warehouse, driving vehicles, on the job site, equipment operation and many other areas. Make sure you address concerns today; tomorrow may be too late. Use checklists to help make sure you cover all hazards and educate workers. WHEN: When must you address safety concerns? In order to have a successful safety program you must address concerns prior to beginning work. Proper orientation of new workers explaining what you expect from them and how being safe is critical. Whenever there are changes in operations, equipment, location, products, personnel or job site hazards, you must educate your workers on how to do the job safely. Don’t ever assume that they know it and make it a point to train them. WHY: Why is safety so important? No one wants to get, or plans to get hurt, but it happens. FAST. Many people say that safety is common sense, but how do you gain common sense? Common sense is gained through training, experience, education and shared knowledge from other people’s experiences. The five minutes you spend going over safety requirements with workers could save them from injury and you hours of time and expense. Definitely, time well spent. HOW: How do you make sure your program is the best? Evaluate and update it on a regular basis. It will require some time and research on your part but, for every minute spent training and every dollar spent on safety the return will be worth it. You are not on your own for this task, use available resources such as the Internet, OSHA, safety consultants and your workers’ comp carrier to assist you in making your safety program successful. One very important factor to remember; if you want your safety program to be successful, everything must start at the top and work down through the ranks. Management must believe in and support the safety program and provide the proper training and equipment to workers. Proper direction and reinforcement from top management will help to assure a successful company safety program.
