**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Causes burns. Contact with combustible material may cause
fire.Corrosive.

Potential Health Effects
Eye:
Causes eye burns. May cause permanent corneal opacification. May
cause chemical conjunctivitis and corneal damage.
Skin:
Causes skin burns. May cause skin rash (in milder cases), and cold
and clammy skin with cyanosis or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. May cause systemic effects. May cause nausea, vomiting, and
diarrhea, possibly with blood.
Inhalation:
Causes chemical burns to the respiratory tract. May cause systemic
effects. May cause acute pulmonary edema, asphyxia, chemical
pneumonitis, and upper airway obstruction caused by edema.
Chronic:
Effects may be delayed.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
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. Get medical aid immediately.
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. 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. 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. Substance is
noncombustible. Use water with caution and in flooding amounts.
Oxidizer. Greatly increases the burning rate of combustible
materials.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire. Contact professional fire-fighters
immediately.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions in the Protective
Equipment section. Wear a self contained breathing apparatus and
appropriate personal protection. (See Exposure Controls, Personal
Protection section). Sweep up, then place into a suitable container
for disposal. Avoid generating dusty conditions. Provide
ventilation.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Remove contaminated clothing and wash before reuse. Minimize dust
generation and accumulation. Do not get in eyes, on skin, or on
clothing. Keep container tightly closed. Avoid contact with clothing
and other combustible materials. Avoid ingestion and inhalation. Use
with adequate ventilation. Discard contaminated shoes.
Storage:
Keep away from heat, sparks, and flame. Do not store near
combustible materials. Do not store in direct sunlight. Store in a
tightly closed container. Store in a cool, dry, well-ventilated area
away from incompatible substances. Corrosives area.

**** 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# 7782-68-5:


Personal Protective Equipment

Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear a chemical apron. Wear appropriate clothing to
prevent skin exposure.
Respirators:
Wear a NIOSH/MSHA or European Standard EN 149
approved full-facepiece airline respirator in the
positive pressure mode with emergency escape
provisions.
