Mihama Refrigerant Gases Freon™/Opteon™ Freon R-134a

Freon R-134a

Freon™ 134a is an HFC retrofit refrigerant for R-12.  It is used in medium- and high-temperature stationary commercial refrigeration, as well as chiller systems and home appliances. In addition, it can be used to retrofit existing R-12 refrigeration and air conditioning systems.

HFC-134a is included in the U.S. EPA SNAP de-listing of HFCs that will no longer be acceptable in new equipment in certain end use applications in the U.S. market. There are no U.S. regulations currently impacting the HFC service market.

EXPOSURE CONTROLS/PERSONAL PROTECTION

Components CAS-No Value type (Form of exposure) Control parameters / Permissible concentration Basis
1,1,1,2-Tetrafluoroethane 811-97-2 TWA 1,000 ppm US WEEL
Engineering measures Ensure adequate ventilation, especially in confined areas. Minimize workplace exposure concentrations.

Personal protective equipment

Respiratory protection General and local exhaust ventilation is recommended to maintain vapor exposures below recommended limits. Where concentrations are above recommended limits or are unknown, appropriate respiratory protection should be worn. Follow OSHA respirator regulations (29 CFR 1910.134) and use NIOSH/MSHA approved respirators. Protection provided by air purifying respirators against exposure to any hazardous chemical is limited. Use a positive pressure air supplied respirator if there is any potential for uncontrolled release, exposure levels are unknown, or any other circumstance where air purifying respirators may not provide adequate protection.
Hand protection Material Low temperature resistant gloves
Remarks Choose gloves to protect hands against chemicals depending on the concentration specific to place of work. For special applications, we recommend clarifying the resistance to chemicals of the aforementioned protective gloves with the glove manufacturer. Wash hands before breaks and at the end of workday. Breakthrough time is not determined for the product. Change gloves often!
Eye protection Wear the following personal protective equipment: Chemical resistant goggles must be worn.Face-shield
Skin and body protection Skin should be washed after contact.
Protective measures Wear cold insulating gloves/ face shield/ eye protection.
Hygiene measures Ensure that eye flushing systems and safety showers are located close to the working place. When using do not eat, drink or smoke.Wash contaminated clothing before re-use.
