**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation and if swallowed. Causes
burns.Corrosive.
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.
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.
Chronic:
Effects may be delayed.
**** 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 sawdust. 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.
