**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes burns. May cause cancer. Harmful by inhalation. Very toxic to
aquatic organisms, may cause long-term adverse effects in the aquatic
environment.Moisture sensitive.
Potential Health Effects
Eye:
Causes eye burns. May cause blindness. Lachrymator (substance
which increases the flow of tears).
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns.
Inhalation:
Harmful if inhaled. May cause severe irritation of the respiratory
tract with sore throat, coughing, shortness of breath and delayed
lung edema. Causes chemical burns to the respiratory tract.
Chronic:
Not available.
**** 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:
**** 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. Use water spray to keep fire-exposed containers
cool. Decomposes at high temperatures, resulting in toxic and
corrosive products. Explosive decomposition may occur under fire
conditions. Combustible liquid and vapor. 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 dry sand or earth to smother fire. Use carbon dioxide. Use dry
chemical. DO NOT USE WATER OR FOAM.
**** 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. Avoid runoff into storm sewers and
ditches which lead to waterways. Remove all sources of ignition.
Provide ventilation. Evacuate unnecessary personnel. Approach spill
from upwind. Spill may be carefully neutralized with soda ash
(sodium carbonate).
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Do not get in eyes, on skin, or on clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind,
or expose empty containers to heat, sparks or open flames. Use only
with adequate ventilation. Keep away from heat and flame. Do not
breathe vapor or mist. Systems and equipment must be scrupulously
dry.
Storage:
Keep refrigerated. (Store below 4C/39F.) Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Bottles should be vented periodically in
order to overcome pressure buildup.
**** 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.
