concentrations, act primarily as asphyxiants without other adverse effects. A
concentration limit is not included for each material because the limiting factor is the
available oxygen. (Several of these materials present fire or explosion hazards.)

This material contains a simple asphyxiant which may displace oxygen. Insure adequate ventilation to
prevent an oxygen deficient atmosphere.
The minimum requirement of 19.5% oxygen at sea level (148 torr O2, dry air) provides an adequate
amount of oxygen for most work assignments.
Exposure controls
Engineering controls: Use only with adequate ventilation. Local exhaust ventilation may be
necessary for some operations. Provide general and/or local exhaust ventilation to control airborne
levels below the exposure guidelines. Exhaust systems should be designed to move the air away
from the source of vapor/aerosol generation and people working at this point. The odor and irritancy
of this material are inadequate to warn of excessive exposure. Lethal concentrations may exist in
areas with poor ventilation.
Individual protection measures
Eye/face protection: Use safety glasses (with side shields).
Skin protection
Hand protection: Use gloves chemically resistant to this material. Examples of preferred glove
barrier materials include: Butyl rubber. Chlorinated polyethylene. Polyethylene. Ethyl vinyl alcohol
laminate ("EVAL"). Examples of acceptable glove barrier materials include: Neoprene.
Nitrile/butadiene rubber ("nitrile" or "NBR"). Viton. Polyvinyl chloride ("PVC" or "vinyl"). NOTICE: The
selection of a specific glove for a particular application and duration of use in a workplace should also
take into account all relevant workplace factors such as, but not limited to: Other chemicals which may
be handled, physical requirements (cut/puncture protection, dexterity, thermal protection), potential
body reactions to glove materials, as well as the instructions/specifications provided by the glove
supplier.
Other protection: Use protective clothing chemically resistant to this material. Selection of specific
items such as face shield, boots, apron, or full body suit will depend on the task.
Respiratory protection: Atmospheric levels should be maintained below the exposure guideline.
When atmospheric levels may exceed the exposure guideline, use an approved air-purifying respirator
equipped with an organic vapor sorbent and a particle filter. For situations where the atmospheric
levels may exceed the level for which an air-purifying respirator is effective, use a positive-pressure
air-supplying respirator (air line or self-contained breathing apparatus). For emergency response or
for situations where the atmospheric level is unknown, use an approved positive-pressure self-
contained breathing apparatus or positive-pressure air line with auxiliary self-contained air supply. In
confined or poorly ventilated areas, use an approved self-contained breathing apparatus or positive
pressure air line with auxiliary self-contained air supply.
The following should be effective types of air-purifying respirators: Organic vapor cartridge with a
particulate pre-filter.
