VENTILATION AND ENGINEERING CONTROLS:
circumstances of use. As with all chemicals, use this gas mixture in well-ventilated areas. If this gas mixture is used in a poorly-ventilated area,
install automatic monitoring equipment to detect the levels of Phosphine and Oxygen.
RESPIRATORY PROTECTION: No special respiratory protection is required under normal circumstances of use. Maintain Phosphine levels below
50% of the TLV (TLV = 0.3 ppm) and oxygen levels above 19.5% in the workplace. Use supplied air respiratory protection when Phosphine levels
exceed 50% of the TLV (TLV = 0.3 ppm), oxygen levels are below 19.5%, or during emergency response to a release of this gas mixture. During
an emergency situation, before entering the area, check the concentration of Phosphine and Oxygen. If respiratory protection is required, follow the
requirements of the Federal OSHA Respiratory Protection Standard (29 CFR 1910.134), or equivalent State standards.
EYE PROTECTION: Safety glasses. If necessary, refer to U.S. OSHA 29 CFR 1910.133 or appropriate Canadian Standards.
HAND PROTECTION: Wear leather gloves when handling cylinders. Chemically resistant gloves should be worn when using this gas mixture. If
necessary, refer to U.S. OSHA 29 CFR 1910.138 or appropriate Standards of Canada.
BODY PROTECTION: No special protection is needed under normal circumstances of use. If a hazard of injury to the feet exists due to falling
objects, rolling objects, where objects may pierce the soles of the feet or where employee's feet may be exposed to electrical hazards, use foot
protection, as described in U.S. OSHA 29 CFR 1910.136.

The following information is for the gas mixture:
APPEARANCE AND COLOR: This gas mixture is a colorless, odorless gas.
HOW TO DETECT THIS SUBSTANCE (warning properties): In terms of leak detection, fittings and joints can be painted with a soap solution
to detect leaks, which will be indicated by a bubble formation.
STABILITY: Normally stable in gaseous state.
DECOMPOSITION PRODUCTS:
Trichlorofluoromethane, and Dichlorodifluoromethane), if exposed to fire, this gas mixture may decompose yielding toxic products (i.e. hydrogen
fluoride, phosgene, hydrogen chloride, carbonyl fluoride). The other components of this gas mixture do not decompose, per se, but can react with
other compounds in the heat of a fire.
MATERIALS WITH WHICH SUBSTANCE IS INCOMPATIBLE: Titanium will burn in Nitrogen (a main component of this gas mixture). Lithium
reacts slowly with Nitrogen at ambient temperatures. Components of this gas mixture (1,1,2-Trichloro-1,1,2-trifluoroethane, Tetrafluoromethane,
Trichlorofluoromethane, and Dichlorodifluoromethane) are incompatible with sodium, potassium, calcium, zinc, and magnesium, powdered
aluminum, and alloys of these metals.
HAZARDOUS POLYMERIZATION: Will not occur.
CONDITIONS TO AVOID: Contact with incompatible materials. Cylinders exposed to high temperatures or direct flame can rupture or burst.
