Temporary emergency exposure limits

AIHA emergency response planning guidelines (ERPGs) and temporary emergency exposure limits (TEELs). 

The Temporary Emergency Exposure Limits (TEEL) are TEEL-0 = 60 ppb TEEL-1 = 145 ppb TEEL-2 = 280 ppb TEEL-3 = 500 ppb. 

The Occupational Safety and Health Administration permissible exposure limit is 3 ppm (lOmgm ) as an 8h, time-weighted average. The American Conference of Governmental Industrial Hygienists and National Institute for Occupational Safety and Health recommend 3 ppm as a ceiling concentration. The Revised (1996) IDLH level is 30 ppm. The temporary emergency exposure limits (TEELs) are TEEL-0, TEEL-I, and TEEL-2 (pgm ) 10000 TEEL-3 (pgm ) 100 000.

Because personal protection is limited to the user and the equipment must be worn for the duration of the exposure to the hazard, it should generally be considered as a last line of defence. Respiratory protection in particular should be restricted to hazardous situations of short duration (e.g. emergencies, maintenance, or temporary arrangements while engineering control measures are being introduced). Occasionally, personal protection may be the only practicable measure and indeed even a legal requirement. If it is to be effective, its selection, correct use and condition are of paramount importance. 

Late in January 1974, this situation changed drastically when it was announced that between 1968 and 1973 three long-time PVC plant operators had died of angiosarcoma, a very rare liver cancer [6,7]. The Occupational Safety and Health Administration (OSHA) issued emergency temporary standards limiting employee exposure in the vinyl chloride and poly(vinyl chloride) industry.
