**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Contact with acids liberates toxic gas. Causes burns. Very toxic to
aquatic organisms.Corrosive.Hygroscopic (absorbs moisture from the
air).
Potential Health Effects
Eye:
Causes eye burns. May cause irreversible eye injury. May cause
blindness. May cause chemical conjunctivitis and corneal damage.
Skin:
Causes skin burns. May be absorbed through the skin in harmful
amounts. Prolonged and/or repeated contact may cause irritation
and/or dermatitis. Contact with skin causes irritation and possible
burns, especially if the skin is wet or moist. May cause skin rash
(in milder cases), and cold and clammy skin with cyanosis or pale
color.
Ingestion:
Harmful if swallowed. May cause severe and permanent damage to the
digestive tract. Causes gastrointestinal tract burns. May cause
perforation of the digestive tract. May cause cardiac disturbances.
May cause systemic effects.
Inhalation:
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. May cause effects similar
to those described for ingestion. Aspiration may lead to pulmonary
edema. May cause systemic effects.
Chronic:
Effects may be delayed.
**** 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. Do NOT allow victim to rub eyes or keep eyes closed.
Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Wash clothing before reuse. Destroy contaminated shoes.
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 immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
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. Wear
appropriate protective clothing to prevent contact with skin and
eyes. Wear a self-contained breathing apparatus (SCBA) to prevent
contact with thermal decomposition products.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Clean up spills immediately, observing precautions in the
Protective Equipment section. Avoid generating dusty conditions.
Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Use only
in a well-ventilated area. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Keep away from heat, sparks
and flame. Do not ingest or inhale. Discard contaminated shoes.
Storage:
Store in a cool, dry place. Keep container closed when not in use.
Store in a tightly closed container. Keep from contact with oxidizing
materials. Keep away from strong acids. 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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
Exposure Limits
CAS# 1313-82-2:
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 minimize
contact with skin.
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. 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.
