●
●
Adequate ventilation systems as needed to control concentrations of airborne
contaminants below applicable threshold limit values. If this gas mixture is used in a
poorly-ventilated area, install automatic monitoring equipment to detect the levels of
component gases.
Respiratory ● In case of insufficient ventilation, wear suitable respiratory equipment. Follow the
OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149.
Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure
limits are exceeded or symptoms are experienced.
Eye/Face ● Wear safety glasses.
Skin/Body ● Wear protective gloves leather gloves when handling cylinders; chemically resistant
gloves when using this gas mixture and clothing .
Environmental Exposure
● Controls should be engineered to prevent release to the environment, including
Controls
procedures to prevent spills, atmospheric release and release to waterways.
