7 HANDLING AND STORAGE
Handling
Avoid breathing gas. Avoid contact with eyes, skin and clothing. Keep container closed. Use only with adequate
ventilation. Do not enter confined spaces unless adequately ventilated.
Storage
Do not apply direct flame to cylinder. Do not store cylinder in direct sun or expose it to heat above 120 F.Do not
drop or refill this cylinder. Keep away from heat, sparks and flames.
8 EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls
Investigate engineering techniques to reduce exposures below airborne exposure limits. Provide ventilation if
necessary to control exposure levels below airborne exposure limits (see below). If practical, use local mechanical
exhaust ventilation at sources of air contamination such as open process equipment.
Eye / Face Protection
Where there is potential for eye contact, wear chemical goggles and have eye flushing equipment available.
Skin Protection
Wear appropriate chemical resistant protective clothing and chemical resistant gloves to prevent skin contact.
Consult glove manufacturer to determine appropriate type glove material for given application.Rinse contaminated
skin promptly. Wash contaminated clothing and clean protective equipment before reuse. Wash skin thoroughly
after handling.
Respiratory Protection
Avoid breathing gas. When airborne exposure limits are exceeded (see below), use NIOSH approved respiratory
protection equipment appropriate to the material and/or its components (full face piece recommended). Consult
respirator manufacturer to determine appropriate type equipment for a given application. Observe respirator use
limitations specified by NIOSH or the manufacturer. For emergency andother conditions where exposure limit may
be significantly exceeded, use an approved full face positive-pressure, self-contained breathing apparatus or
positive-pressure airline with auxiliary self-contained airsupply. Respiratory protection programs must comply with
29 CFR ยง 1910.134.
Airborne Exposure Guidelines for Ingredients
Exposure Limit Value
-Only those components with exposure limits are printed in this section.-Skin contact limits designated with a "Y" above have skin contact effect. Air
sampling alone is insufficient to accurately quantitate exposure. Measures to prevent significant cutaneous absorption may be required.-ACGIH Sensitizer
designator with a value of "Y" above means that exposure to this material may cause allergic reactions.-WEEL-AIHA Sensitizer designator with a value of
"Y" above means that exposure to this material may cause allergic skin reactions.
