OSHA OCCUPATIONAL EXPOSURE LIMITS: ACGIH TL Vs and OSHA/Cal/OSHA PELs have not been established for the HCr-C compounds and for the entire mixture.

(323)776-6233, Fax (310)645-6379 Product: Rho-Tron 225 TM, Revision-04/08-11-2007 Page No. 2 of 11 AEL is the Acceptable Exposure Limit set by the manufacturer of this mixture (HCFC-22Sca/HCFC- 22Scb 45/5S wt% mixture). EEL is the Emergency Exposure Limit set by the manufacturer oftrus mixture (HCFC-225ca/HCFC- 22Scb 4S/SS wt% mixture). Emergency Exposure Limits (EELs) are to be used for short-term emergency exposure control. They are concentrations at which exposure for short periods should not result in permanent adverse health effects or interfere with escape. They should not be confused with ACGIH TLV-TWA or TLV STEL values, which are designed for repeated exposure guidelines. The EEL is needed to avoid anesthetic effects, which could prevent self-rescue. If an EEL is exceeded for the specified duration, evacuation, sheltering in place, or other mitigating steps should be taken.

Remarks

AELs ofHCFC-22Sca and HCFC-22Scb are 2S ppm and 400 ppm, respectively. Though no ACGIH TL V or OSHA PEL are assigned, the manufacturer temporarily recommends that workplace exposure levels be maintained at I 00 ppm or less for the mixture (ca/cb = 4S/SS) until the authorized control level (e.g., ACGIH TLV or OSHA PEL) is assigned. Inhalation: Inhalation of high concentrations of vapor is harmful and may cause hepatitis, heart irregularities, unconsciousness, or death. Intentional misuse can be fatal. Vapors are heavier than air and can reduce oxygen available for breathing. Ingestion: The product may be hazardous. Skin Contact: May cause some irritation to skin. Eye Contact: Vapors may be irritating to eyes. FLRST AID : Inhalation: Remove the person to fresh air. Ifno improvement noticed, then transport to the nearest medical care facility for further treatment.
