SECTION IV FIRST AID MEASURES
First Aid Procedures
Inhalation
Remove to fresh air. Obtain medical
attention if irritation develops or persists.
Administer oxygen if breathing is difficult. Apply artificial respiration if victim is not
breathing.
Eye Contact
In case of contact, immediately flush eyes with plenty of water for at least 20
minutes. Hold eyelids apart during
flushing to ensure rinsing of the entire surface of the eye with water. Obtain medical attention if irritation develops
or persists. DO NOT WEAR CONTACT LENSES
WHEN USING THIS PRODUCT.
Skin Contact
Wash off with water and soap. Obtain
medical attention if irritation develops or persists.
Ingestion
If swallowed, call a

OSHA Flammability Classification |
Flammable
liquid |
Other Flammable Properties Vapors are heavier than air and can form an
explosive mixture with air. Vapors can
travel to a source of ignition and flash back.
Never use welding or cutting torches on or near containers or drums
(even when empty). Product residue or
vapor in drums or container can ignite explosively. Cool warm or bulging containers to ambient
temperature with water from a safe distance.
Then wear eye and face protection and protective clothing while
carefully opening bung to vent pressure.
Extinguishing Media Use the following extinguishing media when fighting
fires involving this material:
alcohol-resistant foam dry chemical carbon dioxide.
Fire Fighting Procedures Evacuate enclosed and surrounding areas. Move containers from fire area if you can do
it without risk. As in any fire, wear
self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved or
equivalent) and full protective gear.
Use water spray to cool containers exposed to fire and disperse
vapors. Keep spills away from sources of
ignition. Dike fire-control water for
later disposal.
SECTION VI
ACCIDENTIAL RELEASE MEASURES
Procedures Remove sources of ignition and ventilate area. Dike far ahead of spill for later
disposal. Absorb spill with inert
material and place in a chemical waste container. Obey relevant local, state, provincial and
federal laws and regulations. Do not
contaminate any lakes, streams, ponds, groundwater or soil. Use personal protective equipment. See Section VIII, Exposure Controls/Personal
Protection.
SECTION VII
HANDLING AND STORAGE
Handling Product is supplied in a stabilized form. Stir well before decanting from drum. Open container carefully as it may be
pressurized. Use portable ventilation if
necessary at job site. Ground and bond
containers when transferring material.
Keep container tightly closed.
Use explosion-proof equipment. Do
not eat, drink, smoke or chew tobacco around material.
Storage Keep in the original container at a temperature not
exceeding 35° C (95° F). Do not store in
direct sunlight. Keep away from
heat. Keep away from sparks, flames and
other sources of ignition. Keep
container closed when not in use. Ensure
the area is well ventilated. Limit
storage of flammable liquids to approved areas equipped with overhead
sprinklers. Protect material from
contamination (refer to Section X for incompatibilities). Fill the container by approximately 80% only
as oxygen (air) is required for stabilization.
With large storage containers make sure the oxygen (air) supply is sufficient
to ensure stability. Residual vapors
might explode on ignition; do not apply heat, cut, drill, grind or weld on or
near this container.

Engineering Controls (Ventilation) Provide general and/or exhaust ventilation to
maintain airborne levels below the exposure limits in Section VIII. Refer to the current edition of Industrial
Ventilation: A Manual of Recommended
Practice published by the American Conference of Government Industrial
Hygienists for information on the design, installation, use, and maintenance of
exhaust systems.
Respiratory Protection A respiratory protection program that meets OSHA
1910.134 and ANSI Z88.2 or applicable federal/provincial requirements must be
followed whenever workplace conditions warrant respirator use. NIOSHs Respirator Decision Logic may be
useful in determining the suitability of various types of respirators.
Eye Protection Use safety glasses with side shields.
Skin Protection Use chemically resistant apron or other impervious
clothing to avoid prolonged or repeated skin contact.
Hand Protection Butyl rubber gloves.
Chemical-resistant gloves should be worn whenever this material is
handled. Gloves should be removed and
replaced immediately if there is any indication of degradation or chemical
breakthrough.
Other Protective Equipment A safety shower and eye wash fountain should be
readily available. To identify
additional Personal Protective Equipment (PPE) requirements, it is recommended
that a hazard assessment in accordance with the OSHA PPE Standard
(29CFR1910.132) be conducted before using this product.
