What respirator do I wear so I am compliant for sanding surfaces on which lead could be present? There are several respirators that may be appropriate, provided one has an understanding of the job-site hazards and OSHA requirements, and has developed an effective respiratory protection program that includes provisions for training, fit testing and medical evaluations. A NIOSHapproved 100-class or HEPA particulate respirator can be used to help reduce exposure to lead dust during manual scraping or sanding. For more information on how to get started with your own respirator program, contact the 3M Occupational Health and Environmental Safety Division Technical Service Department at 800/243-4360 to request a copy of “Guide to Administrative Respiratory Protection Program.”
How much moisture can a concrete slab have in it when a hardwood floor is being installed using Bostik’s Ultra-Set SingleStep? Ultra-Set SingleStep can be used to install wood over any concrete slab that is not wet to the touch. Bostik Inc. does not require a calcium chloride test (ASTM F1869-10) or an in-situ RH probe test (ASTM F2170-09). The combination of recycled rubber in the adhesive maintains proper thickness and the recommended trowel for the wood dimensions will create a uniform layer of adhesive. This layer of adhesive has superior adhesion, moisture protection and sound insulation characteristics.
