**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Harmful by inhalation and if swallowed.Lachrymator
(substance which increases the flow of tears).Light sensitive.
Potential Health Effects
Eye:
Causes eye irritation. Lachrymator (substance which increases the
flow of tears). May cause permanent corneal opacification. May
cause chemical conjunctivitis.
Skin:
Causes skin irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Effects may be delayed 2 to 4 hours. Ingestion of nitrate
containing compounds can lead to methemoglobinemia. May be harmful
if swallowed. May cause visual changes with blurred vision.
Opacities may form in the cornea.
Inhalation:
Causes respiratory tract irritation. May be harmful if inhaled.
Vapors may cause dizziness or suffocation. May cause acute pulmonary
edema, asphyxia, chemical pneumonitis, and upper airway obstruction
caused by edema.
Chronic:
Prolonged exposure may cause anemia and methemoglobinemia,
characterized by dizziness, drowsiness, headache, breath shortness,
cyanosis (bluish skin due to deficient oxygenation of the blood),
rapid heart rate and chocolate-brown colored blood. May cause
reproductive and fetal effects. Effects may be delayed. Laboratory
experiments have resulted in mutagenic 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. Do
NOT allow victim to rub eyes or keep eyes closed.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Do not induce vomiting. 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.
Inhalation:
Remove from exposure and move to fresh air immediately. 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.
Vapors can travel to a source of ignition and flash back. Strong
oxidizer. Contact with other material may cause fire. 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. Use water with caution and in flooding amounts.
Extremely flammable liquid and vapor. Water may be ineffective.
Material is lighter than water and a fire may be spread by the use of
water. 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. Will be easily ignited by heat, sparks or
flame.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. Do NOT use straight streams of
water. Contact professional fire-fighters immediately.
**** 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. A
vapor suppressing foam may be used to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Avoid contact with eyes, skin, and clothing. Empty
containers retain product residue, (liquid and/or vapor), and can be
dangerous. Keep container tightly closed. Avoid ingestion and
inhalation. Store protected from light. 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, sparks and flame.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
Refrigerator/flammables. Store protected from light.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use explosion-proof ventilation equipment. 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.
