Section 3 - Hazards Identification


Appearance: clear, colorless. Flash Point: -18 deg C. Danger! May cause liver damage. May cause lung damage. Corrosive. Causes eye and skin burns. May cause respiratory and digestive tract burns. Harmful if inhaled or swallowed. Extremely flammable liquid and vapor. Vapor may cause flash fire. May be harmful if absorbed through the skin.
Target Organs: Liver, respiratory system, eyes, skin.

Potential Health Effects
Eye: Causes eye burns. May result in corneal injury. May cause chemical conjunctivitis and corneal damage. May cause tearing, conjunctivitis and corneal edema when vapor is absorbed into the tissue of the eye.
Skin: Causes skin burns. May be absorbed through the skin. May cause dermatitis. Methylamine is readily absorbed through the skin and may cause malaise , discomfort, injury and death unless treated promptly.
Ingestion: Harmful if swallowed. Causes gastrointestinal tract burns.
Inhalation: Causes chemical burns to the respiratory tract. May cause pulmonary edema and severe respiratory disturbances. May cause liver abnormalities. Inhalation of methylamine may cause coughing, nausea and pulmonary ede ma. Allergic or chemical bronchitis was reported in a worker exposed t o methylamine in an unpublished report. It is unclear from this report what the actual exposure concentrations were.
Chronic: Effects may be delayed. Repeated or prolonged exposure may result in liver disorders and/or ad verse effects to respiratory system (like bronchopneumonia), eyes, or skin. Exposure in test animals has caused liver toxicity and abnormali ties in blood chemistry and lungs.

Section 4 - First Aid Measures

Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid immediately.
Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse.
Ingestion: If swallowed, do NOT induce vomiting. Get medical aid immediately. If victim is fully conscious, give a cupful of water. Never give anything by mouth to an unconscious person.
Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Runoff to sewer may create fire or explosion hazard. Extremely flammable liquid and vapor. Vapor may cause flash fire. Approach fire from upwind to avoid hazardous vapors and toxic decomposition products. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas.
Extinguishing Media: Use water spray, dry chemical, or "alcohol resistant" foam.

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Avoid runoff into storm sewers and ditches which lead to waterways. Wear a self contained breathing apparatus and appropriate Personal protection. (See Exposure Controls, Personal Protection section). Remove all sources of ignition. Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Do not use combustible materials such as saw dust. Provide ventilation. A vapor suppressing foam may be used to reduce vapors. Approach spill from upwind. Use only non-sparking tools and equipment. Use water spray to cool and disperse vapors, protect personnel, and dilute spills to form nonflammable mixtures. 5% sulfuric acid may be used to neutralize diluted pools.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Discard contaminated shoes. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Do not breathe vapor. Use only with adequate ventilation. Keep away from heat, sparks and flame. Pipes, fittings, pumps, gauges, and other equipment should be made of steel or other material not subject to corrosion by methylamine. Methylamine may attack aluminum, copper, tin, zinc, lead and their alloys as well as rubber and some plastics.
Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Keep container closed when not in use. Store in a tightly closed container. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. Keep away from acids.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits. Ventilation fans and other electrical service must be non-sparking and have an explosion-proof design.
