SECTION III – HAZARDS IDENTIFICATION


Emergency Overview

 

Color:

colorless, turbid

Appearance:

liquid

Odor:

ester-like

 

Flammable liquid and vapor.

May cause sensitization by skin contact.

May be ignited by heat, sparks or flame.

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.
