HAZARDS OP VCM ^ VCM is an anesthetic and its vapor produces, acute symptoms similar to those of hospital anesthetics/ such as dizziness/ disorientation and drowsiness. Severe exposure may lead to more serious effects. The after effects of an acute exposure are minor and disappear quickly. Liquid VCM .may cause frostbite _if allowed to contact and then evaporate from skin. Over a ------'period of yearS/ repeated exposure to high concentrations of VCM vapor may cause certain types of cancor. ____ PURPOSE, USE AND LIMITATIONS OF RESPIRATORS I Our respirators are designed ..to isolate you from the VCM in the workplace atmosphere and to provide you with an alternate, VCM-free atmosphere to breathe. Proper use of our respirators is described in detail in SDP 84-618.02/ "Use of SuppliedAir Respirator System"/ which is posted throughout the operating area. The respirators will adequately protect you from VCM vapors only if used and cared for in accordance with this SDP. In addition/ they require a constant supply of VCM-free air, and even with 'an adequate air supply will not provide the desired degree of protection in atmospheres which contain more than 3600 parts per million (hpm) VCM. However/ 3600 ppm is a^far higher concentration than we routinely encounter in PVC operations as they exist today.: t /th D. L. Gendron R&S158290
