Personal protective equipment should include(impervious gloves, protective eye <br /> wear and suitable work clothes). Adequate ventilation should also be employed so that vapor levels do not exceed <br /> recommended guidelines. If vapor levels are expected to exceed these guidelines,use NIOSH approved, positive pressure, <br /> supplied air respirator or a negative pressure half mask with organic vapor cartridges and dust/mist pre-filters. Exercise good <br /> personal hygiene, wash thoroughly after each use. <br /> Exposure Guidelines OSHA ACGIH <br /> 4,4' —Diphenylmethane .020 ppm ceiling .005 ppm TWA <br /> Diisocyanate(NIDI) .200 mg/m3 ceiling .051 mg/m3 TWA <br /> Higher Oligomers of NIDI None Established None Established <br /> 1,1,1,2-Tetrafluoroethane(Non-Flammable None Established None Established <br /> Compressed Gas,HFC Fluorocarbon 134a) <br /> (None of the components in this product are listed by IARC,NTP,OSHA or ACGIH as a carcinogen). <br /> 9.
