SPECIAL FIRE FIGHTING PROCEDURE
Wear self contained breathing apparatus (pressure demand, MSHA/NIOSH approved or equivalent) and full protective gear. Use water to
cool containers. Fight fire from protected location - EXPLOSION HAZARD
UNUSUAL FIRE AND EXPLOSION HAZARDS
Heat can cause polymerization. Heat sealed containers can explode.
RECOMMENDED WORK PLACE EXPOSURE LIMITS
TWA - See Section I STEL + 75 ppm methyl Methacrylate; 4 mg/M3HQ
IV - HEALTH HAZARD INFORMATION
EFFECTS OF OVEREXPOSURE
SKIN CONTACT: Severely irritating to skin.
EYE CONTACT: Severely irritating possible corneal injury.
INHALATION: Vapor or mist can irritate the nose and throat. Extended exposure will lead to headache, nausea, drowsiness and
unconsciousness .
DELAYED EFFECTS: Prolongs or repeated exposure can cause liver and kidney damage and an allergic reaction to the skin.
EMERGENCY AND FIRST AID PROCEDURES
INHALATION: Move subject to fresh air. Give artificial respiration if breathing has stopped. Seek medical attention.
EYE CONTACT: IMMEDIATELY get under a safety shower. Flush eyes with water while removing contaminated clothing and flooding exposed
skin areas with water. Seek medical attention.
INGESTION: IF swallowed, dilute by giving 2 glasses of water to drink. Seek medical attention. Never give anything by mouth to an an
unconscious person.

VI - SPILL OR LEAK PROCEDURE
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED
Keep spectators away. Eliminate ignition sources. Use self-contained breathing apparatus (pressure- demand, MSHA/NIOSH approved),
impervious clothing and boots. Dike and contain spill with inert material (e.g. sand, earth). Transfer liquid to containers for recovery or disposal
and solid diking material to separate containers for disposal. Contaminated monomer may be unstable. Add extra inhibitor to prevent
polymerization. Remove contaminated clothing promptly and wash affected skin areas with soap and water. Keep spills and cleaning runoffs
out of municipal sewers and open bodies of water. Spills on porous surfaces can contaminate groundwater.
WASTE DISPOSAL METHOD
When discarded, this material is a hazardous waste. RCRA #D-001 (ignitable); reportable quantity 1000 lbs. (40 CFR
Part 302) "Superfund". Incinerate liquid and the contaminated diking material, in accordance with state and federal
regulations.
VII - SPECIAL PROTECTION INFORMATION
VENTILATION TYPE
MECHANICAL local exhaust ventilation at point of contaminant release. (See Section X)
RESPIRATORY PROTECTION
None required if good ventilation is maintained. Otherwise, wear self-contained breathing apparatus (pressure demand, MSHA/NIOSH
approved or equivalent).
PROTECTIVE GLOVES
EYE PROTECTION
Impervious
Chemical splash goggles (AVSI Z-87.1 or approved equivalent)
OTHER PROTECTIVE EQUIPMENT
Eye wash facility, safety shower, imperious clothing.
VII - STORAGE HANDLING INFORMATION
STORAGE TEMPERATURE INDOOR HEATED REFRIGERATED OUTDOOR
MAX. Ambient Min. (1)
Store out of direct sunlight at ambient temperatures. Limit indoor storage of flammable liquids to approved areas equipped with automatic sprinklers.
Leave air space over liquid surface in all containers. Found all containers when transferring material. It is advisable to use material with in six months.
Monitor inhibitor level during storage using CM-18. Materials stored in bulk should be tested for stability every month; drums and pails every three
months.
IX - TOXICITY INFORMATION
Acute oral LD50 - Rat: 7900 mg/kg Acute dermal LD50 - Rabbit: 35,500 mg/kg Acute inhalation LD50 - Rat:> 12,500
to 16, 500 ppm for 0.5 hours Human Patch Test: About 1/3 of 50 subjects developed a mild erythema at the site of
application. 20% of subjects showed evidence of sensitivity when tested 10 test later.
X - MISCELLANEOUS INFORMATION
(1) Monomer stability is a logarithmic function of time vs. temperature. Stability is also dependent on inhibitor
concentraion, the presence of air and type of monomer. NOTE: use local exhaust ventilation with a minimum capture
velocity of 100ft/min. (30 m/min.) at the point of monomer evolution. FOOTNOTE TO SECTION I: NE = not established,
NOT REQ or NR = not required.
