**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Risk of serious damage to eyes.Water-reactive.
Potential Health Effects
Eye:
Causes eye burns. When substance becomes wet or comes in contact
with moisture of the mucous membranes, it will cause irritation. May
cause chemical conjunctivitis and corneal damage.
Skin:
Causes skin burns. 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:
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.
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. Aspiration may lead to
pulmonary edema. May cause systemic effects.
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. Wash clothing before reuse. Destroy
contaminated shoes. If water-reactive products are embedded in the
skin, no water should be applied. The embedded products should be
covered with a light oil.
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 not breathing, give artificial respiration. 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. Contact
with water can cause violent liberation of heat and splattering of
the material.
Extinguishing Media:
Use dry sand or earth to smother fire. DO NOT USE 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:
Avoid runoff into storm sewers and ditches which lead to waterways.
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. Provide ventilation. Do
not expose spill to water.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Do not allow water to get into the
container because of violent reaction. Do not get in eyes, on skin,
or on clothing. Keep container tightly closed. Do not ingest or
inhale. Use with adequate ventilation. Discard contaminated shoes.
Keep from contact with moist air and steam.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from water. 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# 7681-38-1:
Malaysia: 5 mg/m3 TWA
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:
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.

**** SECTION 10 - STABILITY AND REACTIVITY ****
Chemical Stability:
Reacts with water. None of the water-reaction products are gases,
nor are they flammable. If the reaction were to happen all at once,
the heat generated can boil and/or violently spatter the reactant and
products. If the reaction is executed under controlled conditions,
slowly with stirring, there should be no unsafe consequences.
Conditions to Avoid:
Dust generation, excess heat, exposure to moist air or water.
Incompatibilities with Other Materials:
Strong bases.
Hazardous Decomposition Products:
Oxides of sulfur.
Hazardous Polymerization: Has not been reported.
