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

CONDITIONS TO AVOID
Heat, Oxygen-free atmosphere, sunlight.
Other oxidizing or reducing agents, acids and bases, UV light, contamination.
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 akin areas with soap and water. Keep spills and cleaning runoffs
out of municipal sewers and open bodies of water. Fish toxicity: MMA is practically nontoxic to fish. Fathead minnows & Goldfish TLm24;
420ppm; Bluegills TLm24: 368ppm. 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 local, 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 maintain. Otherwise, wear self-contained breathing apparatus (pressure-demand, MSHA/NIOSHapproved
or equivalent).
PROTECTIVE GLOVES
EYE PROTECTION
impervious
Chemical splash goggles (ANSI Z-87.1 approved equivalent)
OTHER PROTECTIVE EQUIPMENT
Eyewash facility, safety shower, impervious 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 container. Ground all containers when transferring materials. It is advisable to use material with six months.
Monitor inhibitor level during storage sing 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 the subjects showed evidence of sensitivity
when tested ten days later.
X - MISCELLANEOUS INFORMATION
(1) Monomer stability is a logarithmic function of time vs. temperature. Stability is also dependent on inhibitor concentration, the
presence of air and type of monomer. Note: Use local exhaust ventilation with a minimum capture velocity of 100 ft/min. (30 m/min.)
at the point of monomer evolution. Refer to Industrial Ventilation: A manual of recommended practice published by the American
Conference of Governmental Industrial Hygienists. Footnote to Section I: NE= not established, NOT REQ or NR= not required.
