EMERGENCY OVERVIEW
Appearance: clear, colorless liquid. Flash Point: -18 deg C.
Danger! Extremely flammable liquid and vapor.
Vapor may cause flash fire. Causes eye and skin burns. Causes
digestive and respiratory tract burns. Harmful if inhaled or
swallowed. May be harmful if absorbed through the skin. May cause
lung damage. May cause liver damage.
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
edema. Allergic or chemical bronchitis was reported in a worker
exposed to methylamine in an unpublished report.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
adverse effects to respiratory system (like bronchopneumonia), eyes,
or skin. Exposure in test animals has caused liver toxicity and
abnormalities in blood chemistry and lungs.
Section 4 - First Aid Measures
|
Eyes:
In case of contact, immediately flush eyes with plenty of water for a
t 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. 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.
Flash Point: -18 deg C ( -0.40 deg F)
Autoignition Temperature: 430 deg C ( 806.00 deg F)
Explosion Limits, Lower:4.90 vol %
Upper: 20.70 vol %
NFPA Rating:
(estimated) Health: 3; Flammability: 3; Instability: 0
Section 6 - Accidental Release Measures
|
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Wear a self contained breathing
apparatus and appropriate personal protection. (See Exposure
Controls, Personal Protection section). Remove all sources of
ignition. Provide ventilation. 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 sources of ignition. Keep container closed when not
in use. Keep from contact with oxidizing materials. 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.
