Emergency Overview
|
Color: |
colorless, turbid |
|
Appearance: |

Vapors can travel to a source of ignition and flash
back.
Danger of bursting of closed systems due to vigorous
exothermic polymerization.
Avoid uncontrolled polymerization.
Container may explode when heated.
May be irritating to respiratory system and skin.
Primary Routes of Exposure – Inhalation and skin contact.
Potential Health Effects:
Inhalation -
May cause irritation to the respiratory tract.
Eye Contact -
This product is not an eye irritant based on animal test data.
Skin contact -
May cause irritation and sensitization of the skin. Not expected to be absorbed through the skin
in toxic amounts.
Ingestion -
Expected to be slightly toxic by ingestion.
Chronic Effects - No chronic (long-term) effects are known for humans.
Aggravated Medical Conditions - Conjunctivitis of the eye, dermatitis of the skin,
asthma and respiratory diseases.
Potential Environmental Effects - See SECTION XII, Ecological Information
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 Poison Control Centre or doctor immediately. Do NOT induce vomiting.

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. NIOSH’s “Respirator Decision Logic” may be
useful in determining the suitability of various types of respirators.
Eye Protection – Use safety glasses with side shields.
Hand Protection – In permeation tests butyl and nitrile rubber gloves
perform better than latex or natural rubber.
Gloves should be replaced regularly, especially after extended contact
with the product. For each work-place a
suitable glove type has to be selected.
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.
