**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Harmful if swallowed.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
May cause central nervous system depression, characterized by
excitement, followed by headache, dizziness, drowsiness, and nausea.
Advanced stages may cause collapse, unconsciousness, coma and
possible death due to respiratory failure. May cause severe
digestive tract irritation with abdominal pain, nausea, vomiting and
diarrhea.
Inhalation:
May cause irritation of the respiratory tract with burning pain in
the nose and throat, coughing, wheezing, shortness of breath and
pulmonary edema. May cause adverse central nervous system effects
including headache, convulsions, and possible death.
Chronic:
May cause paralysis.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid immediately. Wash clothing before reuse. Flush skin
with plenty of soap and water.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure to fresh air
immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
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. 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. Vapors may be heavier than air. They can spread
along the ground and collect in low or confined areas.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or
alcohol-resistant foam. Use agent most appropriate to extinguish
fire. Cool containers with flooding quantities of water until well
after fire is out.
**** 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. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Do not get in eyes,
on skin, or on clothing. Do not ingest or inhale.
Storage:
Store in a cool, dry place. Keep from contact with oxidizing
materials. Keep away from reducing agents. Keep containers tightly
closed.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR ??1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.
