**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Irritating to eyes, respiratory system and skin.Moisture sensitive.
Potential Health Effects
Eye:
Produces irritation, characterized by a burning sensation, redness,
tearing, inflammation, and possible corneal injury. Lachrymator
(substance which increases the flow of tears).
Skin:
Causes skin irritation. May cause skin sensitization, an allergic
reaction, which becomes evident upon re-exposure to this material.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause liver and kidney damage.
Inhalation:
Causes respiratory tract irritation. Exposure produces central
nervous system depression. Can produce delayed pulmonary edema. In
rare instances, exposure may cause sensitization, resulting in
inflammation of the mucous membranes and in eczematous eruptions.
Chronic:
May cause liver and kidney damage. Effects may be delayed. May cause
lung damage. Repeated or prolonged exposure may cause allergic
reactions in sensitive individuals. Inhalation of product may
aggravate existing chronic repiratory problems such as asthma,
emphysema or bronchitis.
**** 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:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
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. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
For ingestion, the stomach sould be intubated, aspirated, and
lavaged with a slurry of activated charcoal--protect the airway from
aspiration of gastric contents. 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. 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. Reacts with water to form acidic gases which when in contact
with metal may liberate flammable and/or hydrogen gas. Runoff from
fire control or dilution water may cause pollution.
Extinguishing Media:
For large fires, use water spray, fog, or alcohol-resistant foam.
For small fires, use carbon dioxide, dry chemical, dry sand, or
alcohol-resistant 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Provide
ventilation. Do not get water inside containers.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Avoid contact with eyes, skin, and clothing. Keep container tightly
closed. Avoid ingestion and inhalation. Use with adequate
ventilation. Do not allow contact with water. Wash clothing before
reuse. Discard contaminated shoes. Keep from contact with moist air
and steam.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Store
protected from moisture.
**** 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
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 621-30-7:
Personal Protective Equipment
Eyes:
Wear chemical splash goggles.
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 respirator use.
