Personal Protection
Eye/Face Protection: Use safety glasses (with side shields).
Skin 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.
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.
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.
Ingestion: Use good personal hygiene. Do not consume or store food in the work area. Wash hands
before smoking or eating.
Engineering Controls
Ventilation: 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.
