Introduction We would recommend that instruction should be given to potential wearers of these suit systems during normal site induction when the equipment is issued. As these are specialist garments it is imperative that the fundamental parts of the suit and its construction are included in the induction process. The care of water seals and waterproof zips must be highlighted during induction so that the wearer understands the function of the suit and the correct method of donning and removal of the garment. This will ensure the suit is worn correctly and that the correct use will increase the working life of the suit and the seals.

WARNING ALL USERS MUST UNDERGO TRAINING AND FAMILIARISATION WITH A CERTIFIED INSTRUCTOR BEFORE USING THIS PRODUCT. PLEASE NOTE THAT THIS SUIT CONTAINS NO INHERENT BUOYANCY AND IS DESIGNED TO BE USED AT ALL TIMES WITH A SOLAS APPROVED LIFE JACKET The following are important safety guidelines every user should adopt: Follow a complete offshore survival course with a certified instructor and from an officially recognized approved training agency. Become familiar with all your equipment before use. Inspect the zip and seals for damage before each use. Perform regular preventative maintenance on the suit, zip and seals. Only allow qualified individuals to perform service on the suit. Understand your personal limitations. Do not exceed them.

Key Specifications Tri-laminate Tri-laminate suits are constructed from a three-layer fabric (hence the name trilaminate) consisting of a middle waterproof barrier of butyl rubber sandwiched between a tough nylon exterior and special polyester blend interior. The suit is sewn together with a purpose-modified sewing machine that provides a stitch that stretches. Then the inside surface of the seam is treated with a special heat reactive polymer, and sealed with a waterproof tape applied with a computercontrolled hot air welding machine. This provides an extremely dry and reliable seam. The tri-laminate suit operates on a slightly different principle than the neoprene, as the tri-laminate material has neither inherent buoyancy nor thermal protection. This style, known as a â&#x20AC;&#x153;membraneâ&#x20AC;? suit, simply provides a waterproof shell under which the user can wear the correct choice of undergarments to suit the prevailing weather conditions.

Transit Suit Manual | East Quarry, Appley Lane North, Appley Bridge, Wigan, WN6 9AE, UK

Suit Zip Your suit will be fitted with a YKK® Aquaseal® dry zip. The zip teeth must be kept clean and lubricated to operate properly for long product life. Your suit zip is situated diagonal on the front section of the torso (front entry). You must place one finger directly in front of the slider as it is closed, helping to guide the undergarment or foreign objects away from the zip teeth. Also make sure that you fully tuck in the interior zip flap before closing the zip. Always pull the slider slowly and in the direction it is travelling (never pull it at an angle). Ensure that there is no hair or clothing caught in the zip and that the zip has been fully opened before you put on your suit. Failure to open completely may result in the zip being damaged. The zip must be fully opened before you remove your suit. Clean the zip with fresh clean water. If the zip is particularly dirty, a toothbrush can be used. If using a toothbrush, do so gently. Mild soapy water can be used for heavy soiling. Close the zip when you hang / store the suit. Do not fold, bend or apply pressure to the zip (other than the small amount of pressure required to open and close it).

WARNING CLOTHING OR FOREIGN OBJECTS CAUGHT BETWEEN THE ZIP TEETH WILL CAUSE THEM TO SEPARATE, DESTROYING THE WATERPROOF INTEGRITY OF THE ZIP. THIS DAMAGE IS PERMANENT AND IS NOT REPAIRABLE. YOU MUST EXERCISE CARE WHEN CLOSING/OPENING THE ZIP. YKK® Aquaseal® suit zip Before using the suit, apply a suitable lubricant on the areas on the zip stop that the slider comes in contact with. Our Zip Wax must not be used with this zip, nor should any other wax-based lubricant. McNett Ziptech™ or Molykote® 33 have been tested by YKK® and are the lubricants that YKK® recommends. Slowly open and close the zip a few times. This will lubricate all the necessary zip components.

Neoprene neck & wrist seals Neoprene seals can become more supple with use. If you find they are unpleasantly tight, the seals can be stretched simply by plugging the wrist and neck seals with objects of a suitable size and leaving for 12 to 24 hours. Storage & maintenance Store the suit so the seals are dry, cool (below 25°C) and out of direct sunlight. If the seals have been exposed to cold temperatures, they will become stiff and lose their flexibility. This condition is not permanent and can be resolved by a brief immersion in warm water. Before storing the suit for any length of time, dust the seals inside and out with pure talc (available to buy separately) as a preservative. Do not use perfumed cosmetic talc, as it contains oils, which can damage. Do not use oils or lotion on the seals. Avoid contact with copper.

Fitting Of A Suit - First remove your watch as it could tear wrist seals. - You should be able to reach both hands over your head, and be able to squat on your knees without restriction, while wearing the drysuit and the heaviest undergarments you intend to wear. - The suit should not be tight in the crotch, or too long. To ensure a good fit: - Wear the Metalux Arctic undersuit, neoprene socks and Hotsox under the suit. Please note: thermal garments with equivalent thermal properties to the products listed may be used. - Make sure the suit is not restrictive in any area. - Make sure you can raise both hands above your head, touch your toes, and squat to your knees without restriction. - Make sure the crotch (with braces properly adjusted) is not more than 10cm (4 inches) below your crotch. - Put on the Rock Swim Safety Boots over the suit socks. Donning the suit First remove your watch as it could tear wrist seals, lay the suit out flat and do a quick overall inspection to ensure it is in good order. Lubricate the neoprene seals using Northern Diver Drysuit Seal Lubricant (supplied in the maintenance kit). Lubricate the zip a suitable lubricant for YKK® Aquaseal® drysuit zips. Remove all jewellery – sharp edges can destroy the seals. Fold the torso of the suit inside out over the legs to about waist level, so the braces are exposed. Make sure the braces are correctly attached, and are not tangled or twisted. Sit down if possible and insert foot first into the suit, making sure you do not tangle foot in braces. Transit Suit Manual | East Quarry, Appley Lane North, Appley Bridge, Wigan, WN6 9AE, UK

Grasp suit material at calf level and gently ease foot into sock. Pull up on leg. Repeat with other leg. Grasp torso and ease suit up so that the crotch of the suit is correctly positioned. Raise braces over shoulders and adjust so they support the weight of the suit. When present, fold the outer cuffs back away from the seals. Insert first arm all the way, taking care with the seal when pushing hand through. Repeat with second arm. Try to make sure the inside zip flap is not curled under during this process. Make sure that if the drysuit undergarment is equipped with thump loops, they are fully retracted, and not caught between the seal and your wrist. This will cause a leak. Pull up on the zip to close. Excessive force should not be required if the zip is correctly maintained. Position of the zip and neck seal closure can be adjusted to suit the prevailing conditions. Once you have donned the suit you can put on the Rock Swim Safety boots. Removing the drysuit Remove the Rock Swim Safety boots. To take off the suit, undo the neck seal if closed and pull down the zip completely. Slide the suit down off the shoulders and grip the outer cuff protector. DO NOT pull on the neoprene cuff seal.

WARNING PULLING ON THE CUFF SEAL COULD SPLIT AND DAMAGE THE NEOPRENE. TAKE EXTRA CARE WHEN REMOVING ARMS FROM THE SUIT.

Pull on the outer cuff protector as instructed on the suit. This will cause the neoprene cuff seal to reverse allowing it to pass easily over the hand without causing any damage. Slide the braces over the shoulders, pull the top of the suit down to the waist then ease over the hips. Sit down and pull each leg out of the suit. The suit should now be fully removed allowing you to remove your thermal garments e.g. Metalux Arctic undersuit, neoprene socks and Hotsox.

Applications for Use Our tri-laminate suits are made of the finest materials and to extremely high standards of workmanship. However, they must be used within reasonable limits. WARNING - DO NOT: - Use the suit without a SOLAS life jacket Pre-use suit checks Before EVERY use, make sure the suit is in good condition by checking the following: - No visible damage to materials or accessories anywhere on the suit. - Check smooth-skin neoprene seals for small tears or holes. Inspect waterproof zip for excess wear, any damage and for sufficient lubrication. Post-use suit checks After EVERY use, complete all the pre-use checks listed above, and inspect suit for any possible new damage. Repair any damage immediately, or take the suit to Northern Diver for repair. When you have finished using the suit for the day, thoroughly rinse the outside of the suit with fresh clean water to remove any dirt, sand or salt. Any stubborn stains can be removed by rubbing the area gently with soapy water. Clean seals with fresh water. Occasionally rinse the inside, which can be treated with a proprietary deodoriser. Inspection intervals In addition to the checks listed above to be performed before every use, the suit should be inspected and serviced on an annual basis.

Risk Assessment Hyper/hypothermia Suits are often used in extreme temperature conditions, where there may be combinations of cold surface conditions and cold water, or hot surface conditions and cold water. It is important to know your own personal thermal safe range, to avoid over heating, or becoming chilled. While a suit and warm undergarment have excellent thermal protection, they do have limits and your safe and enjoyable time on the water is variable based on water temperature and condition, workload, and your own body type. Hypothermia is the cooling of the body core to unsafe levels. Hyperthermia is the overheating of the body core to unsafe levels. Hyperthermia in suit use is most often experienced during prolonged exposure in hot weather, or during periods of excessive workload in warm, shallow water.

Transit Suit Manual | East Quarry, Appley Lane North, Appley Bridge, Wigan, WN6 9AE, UK

WARNING Learn your own limitations and learn to recognise discomfort as a danger signal. Avoid Hyperthermia & Hypothermia as both can be harmful or fatal. Monitor your work rate during all activities to avoid excessive air consumption, fatigue, over heating and other symptoms. The thermal properties of the Transit Suit according to the SOLAS requirements are guaranteed only under the condition that the user wears the recommended garments listed below: Item Brand/Manufacturer Thermal Properties Metalux Arctic Undersuit Neoprene Socks Hotsox Socks Rock Swim Safety Boots

More information on the above items can be found from page 20 of this manual. If you do not use the products listed thermal garments with equivalent thermal properties must be used. Thermal protection rating of immersion suits Due to the construction methods and materials used in all membrane immersion suits a low level of thermal insulation will be achieved unless used in conjunction with suitable warm under and intermediate clothing. To this end the international standard for testing Constant Wear suits requires the manufacturer to specify the components of the suit system including any underclothing and additional items. The primary propose of the protection achieved from a dry seal suit such as the transit suit is to protect against cold shock. This is when the body is suddenly immersed in cold water. The secondary purpose is to give a level of thermal protection when worn with the appropriate under clothing. According to many studies the highest contributing factor to drowning is cold shock. There have been studies as far back as 1922. The Merchant Shipping Advisory Committee on life saving appliances and more recent study conducted by the RLNI. All these studies have come to the conclusion that protection from cold water touching the skin in the early stages of immersion is one of the leading factors that increases the survival of the casualty. The four stages where death can occur as a result of sudden cold-water immersion have been recognized by the scientific community since before World War II. These are: Cold Shock—kills in 3–5 minutes. Swimming Failure—kills in 5–30 minutes. Hypothermia—kills after 30 minutes. Post-Rescue Collapse—kills during or hours after rescue.

| +44 (0) 1257 25 69 49 | neil@ndiver.com | www.ndiver-commercial.com

As the planned recovery time is 15 minutes or less for most of the Wind Farm development sites it is this period that is most important. The first two stages of immersion—cold shock and swimming failure—kill more than half the people who drown. If a dry seal suit is worn in conjunction with a suitable life jacket such as the Falcon 275 the first 2 risks (Cold Shock & Swimming Failure) to the casualty can be reduced to a manageable point in respect of site risk assessments. It’s especially important to protect the casualty from first stages of drowning. To do that effectively, keeping the casualty dry is vital. Suits that offer thermal protection without the dry seal capability do not protect the user from cold water shock. In the wind farm and offshore transfer context where fast recovery is anticipated the flooding suit type does not protects the user from the most influential effects on the casualty’s condition which is cold shock.

WARNING Users should be aware that heat exhaustion may result from wearing undergarments which give thermal insulation too high for the prevailing weather conditions and/or the task being carried out. Northern Diver advise that the following table is used when deciding which undergarment is most suitable for the prevailing conditions. This assumes exposure to the stated water temperature for a period of 2 hours, against a procedural requirement of 12 minutes exposure when immersed. Water Temperature

Recommended Undergarment

2ºC

Thermicore undersuit

5ºC

Recommended clothing listed above

10ºC

Thermalskin undersuit

Note: The user of the suit is responsible for ensuring they are comfortable in the prevailing weather conditions. Sea state, wind-chill and the users physique can all have an effect on how suitable the undergarments are for the working conditions and the above table is intended as a guide only. Correct maintenance A suit is a complex piece of equipment designed to keep a user comfortable in extreme conditions. Treat it with respect, maintain it correctly, and inspect it for wear and damage BEFORE & AFTER each use. Failure to take these precautions may be hazardous. Allergies A small percentage of people are known to experience allergic reaction to neoprene. Although this is less of a problem with suits worn in conjunction with an undersuit to separate the suit from his or her body, some exposure can still result. Be sure to determine you are free from neoprene allergy before purchasing any neoprene product. Transit Suit Manual | East Quarry, Appley Lane North, Appley Bridge, Wigan, WN6 9AE, UK

Troubleshooting NOTE: A properly functioning suit is a closed environment and a certain amount of condensation on the inside of the suit is natural. Users exerting a lot of energy or spending time above water on a warm day with the suit closed will notice this more. Zip leaks Slider not closed all the way – have your buddy check for full closure. Zip has failed – inspect for split in closed teeth. Zip material failed – can either be punctured or damaged by abrasion. Foreign material caught in teeth – dirt, sand, debris, or the suit undergarment is frequently the trouble. The zip is old, worn out, or damaged in some other way – have it replaced. Improper or inadequate lubrication of the zip. Seal leaks Seals leak for two reasons, damage or interference. Check the seals for holes or tears caused by sharp objects, wear and tear, or chemical damage. Check that there are no foreign objects such as hair and sections of undergarment. Check they do not have folds that can create leaking channels, especially around the tendons in wrists. Damage to suit fabric The suit fabric may leak due to wear, abrasion, puncture or tearing. Avoid sharp and abrasive objects. Users exposed to corrosive chemicals must take extra care cleansing and rinsing the suit after each exposure. Some chemicals can degrade or de-laminate the suit materials to the point of failure.

Leak testing your suit Your suit can be tested for leaks by plugging the wrist and neck seals with objects of suitable size, closing the zip and using the low-pressure inflation hose to inflate the suit. Wrap an elastic band around the seal to help the plug stay in place under pressure.

WARNING DO NOT use GLASS objects to plug the neck or wrist seals. Occasionally, the internal pressure will blow the plug out of the seal. Glass can shatter, causing injury.

| +44 (0) 1257 25 69 49 | neil@ndiver.com | www.ndiver-commercial.com

Once the suit is inflated, submerge it a section at a time in the bathtub, and inspect for leaks. Small bubbles will appear if a leak is present. Alternately, lay the inflated suit down outside, and slowly pour warm soapy water over the suspected areas. The soap solution will blow small bubbles, or create fine foam over the leak. Once the leaks are located, mark the area, rinse and dry the suit thoroughly, and repair the leak or book your suit in for a professional repair service at Northern Diver.

Repairing a Leak Ensure the suit is completely dry. Wear protective gloves, such as latex gloves. Mark the puncture on the outside of the suit, and use this mark to mark the same area on the inside of the suit. Clean the puncture area by rubbing with sandpaper, and remove any loose particles. Apply 3 layers of Suit Seal (supplied in the maintenance kit), allowing 15 minutes’ drying time between each application. Note: Rub the first coat of Suit Seal in thoroughly until it soaks into the material – ensure the Suit Seal isn’t just ‘floating’ on the material’s surface, as this will make the repair less effective. Apply 3 layers of Suit Seal to a repairs patch (supplied in the maintenance kit), again allowing 15 minutes’ drying time between each application. Place repairs patch on the damaged area of the suit and use a roller to push out any air bubbles and ensure the patch and suit are firmly bonded together. Allow 3 hours for the Suit Seal to dry, once dry test your suit again to ensure the leak has been repaired. If you prefer, Northern Diver can provide this service. With over 25 years’ experience, our repairs and alterations department has your drysuit in safe hands. When suits come in for repair they are inspected, tested, worked upon and tested again before they return to the customer. Custom options are also available on Northern Diver suits if you wish to add different elements to what you have purchased. We can change neck, wrists, socks, and boots to suit your requirements or add pockets, reflective panels and Kevlar® reinforcement on high wear areas.

Apollo Bio-Seals Heralded by DIVER magazine as “truly keeping the water out”. Some users may experience a trickle of water down their seals now and again, usually as a result of a channel caused by a tendon. Hopefully not for much longer. Apollo has launched this innovative product to combat water ingress, which works excellently. The seals simply slide over your neck and wrists, and form an effective bond with your suit seal, whether you use neoprene or latex seals. The Cosmo-gel that the seals are made from is super soft and super stretchy (1300% - 1500% stretch). As you could deduce, they are very comfortable and mould to your skin brilliantly. On top of this, durability isn’t compromised. This product is latex free. LED Flexi-Light Sticks (Available with 3M™ Tape, Hook Fastener and Clip) High intensity LED that projects light through a flexible silicone stick. The Flexi-Light has a simple press-to-operate button under the coloured marker, which activates flashing, constant and off modes. Light sticks are re-usable and versatile. Mode 1: Flash, 36h burn time, mode 2: Constant, 20h burn time.

Internal Braces Come in handy post-use, if you wish to roll down the top half of your suit, without removing your suit completely.

Northern Diver Undersuits Undersuits provide crucial thermal protection, trapping air and maintaining body heat during use. Modern undersuits can range from simple fleece type garments to advanced suits with anti-compression panels or even built-in heating. Your thermal requirements will depend on water temperature, your suit type and how much you feel the cold. Water transfers heat from the body up to 25 times faster than air which means a user will quickly start to feel the cold without protection. The colder the water, the quicker the onset and the greater the need for undersuits and base layers. Suits have their own thermal properties; some are much better than others. neoprene suits are much warmer and require thinner undersuits, but membrane suits provide very little thermal protection and therefore require thicker or even layered undersuits. Too much insulation can lead to dangerous overheating. Too little insulation can lead to the effects of hypothermia and death. Always ensure that body extremities are also well insulated-wear suitable gloves, hood/hat and socks or boots.

ANTISTATIC FOOTWEAR. Antistatic footwear should be used if it is necessary to minimise electrostatic build up by dissipating electrostatic charges, thus avoiding the risk of spark ignition of for example flammable substances and vapours, and the risk of electric shock from any electrical apparatus or live parts has not been completely eliminated. It should be noted however that antistatic footwear cannot guarantee an adequate protection against electric shock as it introduces only a resistance between foot and floor. If the risk of electric shock has not been completely eliminated, additional measures to avoid the risk are essential. Such measures, as well as the additional tests mentioned below, should be a routine part of the accident prevention programme of the workplace. Experience has shown that, for antistatic purposes, the discharge path through the product should normally have an electrical resistance of less than 1000MÎŠ at any time throughout its useful life. A Value of 100KÎŠ is specified as the lowest limit of resistance of a product when new, in order to ensure some limited protection against dangerous electric shock or ignition in the event of any electrical apparatus becoming defective when operating at voltages up to 250V. However, under certain conditions, users should be aware that the footwear might give inadequate protection and additional provisions to protect the wearer should be taken at all times. The electrical resistance of this type of footwear can be changed significantly by flexing, contamination or moisture. This footwear will not perform its intended function if worn in wet conditions. It is, therefore, necessary to ensure that the product is capable of fulfilling its designed function in dissipating electrostatic charges and also giving some protection during the whole of its life. The user is recommended to establish an in-house test for electrical resistance and use it at regular and frequent intervals. Class I footwear can absorb moisture if worn for prolonged periods and in moist and wet conditions can become conductive. If the footwear is worn in wet conditions where the soling material becomes contaminated, wearers should always check the electrical properties of the footwear before entering a hazard area. Where antistatic footwear is in use, the resistance of the flooring surface should be such that it does not invalidate the protection provided by the footwear. In use, no insulating elements with the exception of normal hose should be introduced between the inner sole of the footwear and the foot of the wearer. If any insert is put between the inner sole and the foot, the combination footwear/ insert should be checked for its electrical properties.

PENETRATION RESISTANT FOOTWEAR The penetration resistance of this footwear has been measured in the laboratory using a truncated nail of diameter 4,5 mm and a force of 1100N. Higher forces or nails of smaller diameter will increase the risk of penetration occurring. In such circumstances alternative preventative measures should be considered. Two generic types of penetration resistant insert are currently available in PPE footwear. These are metal types and those from non-metal materials. Both types meet the minimum requirements for penetration resistance of the standard marked on this footwear but each has different additional advantages or disadvantages including the following: Metal: Is less affected by the shape of the sharp object / hazard (ie diameter, geometry, sharpness) but due to shoemaking limitations does not cover the entire lower area of the shoe. Non-metal â&#x20AC;&#x201C; May be lighter, more flexible and provide greater coverage area when compared with metal but the penetration resistance may vary more depending on the shape of the sharp object / hazard (ie diameter, geometry, sharpness). For more information about the type of penetration resistant insert provided in your footwear please contact the manufacturer or supplier detailed on these instructions.

Neoprene socks Neoprene products need to be properly cared for and maintained, which means doing the right checks before and after use, cleaning them properly and storing them correctly. This will guarantee they last you a long time.

Neoprene degrades naturally over time, generally very slowly, through oxidization. Oxidized material tends to contract and become stiffer. The effects of sunlight (specifically the UV ranges) and heat increase this process, with certain environmental pollutants also accelerating the effects. Neoprene products lifespan is therefore a result of the amount of time it is exposed to light, heat and the elements. Initial signs of degradation are the emergence of small splits/cracks across the outer surfaces that are most exposed to UV light. These are caused by a contraction/hardening of the outer layer of neoprene, thereby losing its flexibility. Initial signs of degradation are to be expected after around 3 years of use, however environmental factors may reduce this. Transit Suit Manual | East Quarry, Appley Lane North, Appley Bridge, Wigan, WN6 9AE, UK

The thermal performance is not dramatically affected by the initial stages of degradation. However as it ages and the splits increase in size, eventually reaching through the neoprene, the insulation properties are reduced. It is advisable to ensure that the natural aging of the neoprene happens as slowly as possible â&#x20AC;&#x201C; essentially by reducing exposure to harmful factors. This can be helped by following the below instructions: Keep out of direct sunlight whenever possible. This includes during drying after use. Do not use heat to dry (i.e. no tumble dryers, heaters, radiators etc.) Pat dry with a towel and allow to air dry completely. Do not use in chlorinated or chemically treated water (e.g. swimming pools) â&#x20AC;&#x201C; the chemical can attack the neoprene and seams. Always rinse with fresh water after use to remove any salt deposits, dissolved pollutants etc. For machine washable instructions follow advice given on garments inner label or contact us with any questions. Keep clean and dirt free. Avoid contact with sharp/abrasive surfaces. These can affect the stitched seams and neoprene fabric. Do not fold the neoprene for compact storage, this can have a detrimental effect on the insulation efficiency. DO NOT DRY CLEAN. DO NOT USE BLEACH. DO NOT MACHINE DRY.

Hotsox, thermal socks These are made from moisture-wicking fleece, keeping your feet warm and comfortable. The socks are double sided and flatlock stitched - no raised seams to cause discomfort. They have a special heel protector and are cut to fit perfectly. Moisture is always present inside any suit, often produced by the users body. Hotsox socks wick this moisture away from the skin to keep you comfortable.
