|5. Fire Fighting Measures|
|Some of these materials may react violently with water.|
Small Fires: Dry chemical, CO2, water spray or alcohol-resistant foam.
Large Fires: Water spray, fog or alcohol-resistant foam. Move containers from fire area if you can do it without risk.
Dike fire control water for later disposal; do not scatter the material. Do not get water inside containers.
Fire involving Tanks or Bulk Containers: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
Cool containers with flooding quantities of water until well after fire is out.
Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from the ends of tanks. For massive fire, use unmanned hose holders or monitor nozzles;
if this is impossible, withdraw from area and let fire burn.
Isolate spill or leak area immediately for at least 50 to 100 metres (160 to 330 feet) in all directions.
Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate closed spaces before entering.
Wear positive pressure self-contained breathing apparatus (SCBA).
Wear chemical protective clothing which is specifically recommended by the manufacturer.
It may provide little or no thermal protection.
Structural firefighters' protective clothing is recommended for fire situations ONLY; it is not effective in spill situations.
If ROAD OR RAIL TANKER is involved in a fire, ISOLATE for 800 metres (1/2 mile) in all directions;
also, consider initial evacuation for 800 metres (1/2 mile) in all directions.
|6. Accidental Release Measures|
|Person-related safety precautions:|
Wear protective equipment. Keep unprotected persons away.
Ensure adequate ventilation
Keep away from ignition sources
Measures for environmental protection:
Do not allow material to be released to the environment without proper governmental permits.
Measures for cleaning/collecting:
Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust).
Use neutralizing agent.
Dispose contaminated material as waste according to item 13.
Ensure adequate ventilation.
Keep away from ignition sources.
|7. Handling And Storage|
Information for safe handling:
Keep container tightly sealed.
Store in cool, dry place in tightly closed containers.
Ensure good ventilation at the workplace.
Information about protection against explosions and fires:
Keep ignition sources away.
Protect against electrostatic charges.
Fumes can combine with air to form an explosive mixture.
Requirements to be met by storerooms and receptacles:
No special requirements.
Information about storage in one common storage facility:
Keep away from heat and direct sunlight.
Store away from oxidizing agents.
Do not store together with alkalies (caustic solutions).
Further information about storage conditions:
Protect from heat and direct sunlight.
Protect from frost.
Store in a cool place. Heat will increase pressure and may lead to the receptacle bursting.
Keep container tightly sealed.
Store under lock and key and with access restricted to technical experts or their assistants only.
|8. Exposure Controls/Personal Protection|
|Occupational Exposure Limits||T W A OEL-RL SHORT TERM OEL-RL|
PPMa) MG/M3b) PPMa) MG/M3b)
--------- --------- --------- ---------
10 30 sk 20 60
|Controls||The control measures appropriate for a particular worksite depend|
on how this material is used and on the extent of exposure.
The best protection is to enclose operations and/or provide
local exhaust ventilation at the site of chemical release.
Use a non-sparking, grounded ventilation system separate from other
exhaust ventilation systems. Exhaust directly to the outside.
Supply sufficient replacement air to make up for air removed.
Have a safety shower/eye wash fountain readily available in the immediate work area
|Personal Protection||If engineering controls and work practices are not effective in|
controlling this material, then wear suitable personal protection
equipment, including chemical safety goggles & face shield, boots,
imperious gloves, coveralls, & respiratory protection.
Have appropriate equipment available for use in emergencies.

Sensitization: No sensitizing effects known.
Subacute to chronic toxicity:
Corrosive materials are acutely destructive to the respiratory tract, eyes, skin and digestive tract. Eye contact may result in permanent damage and complete vision loss. Inhalation may result in respiratory effects such as inflammation, edema, and chemical pneumonitis. May cause coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. Ingestion may cause damage to the mouth, throat and esophagus. May cause skin burns or irritation depending on the severity of the exposure.
Acrylic acid is corrosive to skin, eyes and mucous membranes. Inhalation has resulted in nasal lesions in rats and mice. Teratogenic and reproductive effects in laboratory rats has been reported.
