Employees engaged in the spraying of asbestos the removal or demolition of pipes structures or equipment covered or insulated with asbestos and in the removal or demolition of as- bestos insulation or coverings shall be provided with respiratory equipment in accordance with paragraph d 2 iii of this section and with clothing in accordance with paragraph d 3 of this section special What this section has done in effect has discarded the TLV of 5 fibers per cubic centimeter completely and has directed the user to use certain respiratory equipment and clothing In simple terms the respiratory equipment referred to is a supplied respirator either continous or pressure demand type These types of respirators have an external source of air breathes The external source is either from a pressure which the employee tank or via air * hoses to the respirator The special clothing includes coveralls head cover- ing gloves and foot covering The employer shall provide 2 separate lockers or containers for each employee to isolate the contaminated clothing Launder- ing of contaminated clothing shall be done to prevent the release of airborne asbestos fibers If laundering is to be done by others the clothing shall be conveyed to the launderer in sealed impermeable containers and informed the clothing is contaminated with asbestos fibers In addition to the above other items in the standard state a Posting of caution signs in areas where asbestos is being used b Waste disposal in sealed containers c Exposure records on each employee d Employees to have reasonable access to any record required to be maintained e Notice to employee in writing if he has been exposed to airborne concen- trations of asbestos in excess of the limits prescribed 09 0995 The standard considers asbestos as a hazardous material and if a company is to use it it has to comply with some very strict regulations As noted some of these regulations are so restrictive that it creates extreme difficulty as well as delays in completing projects A number of users have decided not to use asbestos based materials and have started using Quigley's asbestos PANELEX insulation PANELEX has been specifically formulated without asbestos to meet OSHA standards PANELEX was introduced to the market in February of 1972 and has proven to be a high quality easy to use insulation It is available as a castable trowel and spray mix block and special shapes 12/12/72 09 0996
