**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. Extreme
risk of explosion by shock, friction, fire or other sources of
ignition. Danger of cumulative effects. Very toxic to aquatic
organisms, may cause long-term adverse effects in the aquatic
environment.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful
amounts.
Ingestion:
Poison by ingestion. May cause severe digestive tract irritation
with abdominal pain, nausea, vomiting and diarrhea.
Inhalation:
Harmful if inhaled. Causes cyanosis (bluish discoloration of skin
due to deficient oxygenation of the blood). May cause effects
similar to those described for ingestion.
Chronic:
May cause reproductive and fetal effects.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately. Treat patient as for inhalation.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Remove all contaminated clothing immediately. Treat
patient as for inhalation.
Ingestion:
Get medical aid immediately. Do not give anything by mouth. Treat
patient as for inhalation.
Inhalation:
Remove from exposure and move to fresh air immediately. Do NOT use
mouth-to-mouth resuscitation. Keep warm and at rest. Administer
oxygen. If breathing has ceased apply artificial respiration using
oxygen and a suitable mechanical device such as a bag and a mask.
SPEED IS ESSENTIAL, OBTAIN MEDICAL AID IMMEDIATELY.
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. This
material is an explosion hazard when exposed to heat, mechanical
shock, or friction.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Wash area with soap and water. Clean up spills immediately,
observing precautions in the Protective Equipment section. Sweep up,
then place into a suitable container for disposal. Avoid generating
dusty conditions. Isolate area and deny entry. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Avoid contact with eyes, skin, and
clothing. Keep away from heat, sparks and flame. Avoid ingestion and
inhalation. Use only in a chemical fume hood. Avoid mechanical shock
and friction.
Storage:
Keep away from heat, sparks, and flame. Store in a cool, dry place.
Store in a tightly closed container.
**** 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 only under a
chemical fume hood.
Exposure Limits
CAS# 1335-31-5:
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 gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
