**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Contact with water liberates extremely flammable gases. Toxic if
swallowed. Causes burns.Water-reactive.Hygroscopic (absorbs moisture
from the air).
Potential Health Effects
Eye:
May cause irreversible eye injury. When substance becomes wet or
comes in contact with moisture of the mucous membranes, it will cause
burns.
Skin:
May be absorbed through the skin. May cause severe skin irritation
with possible burns, especially if skin is wet or moist.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea,
vomiting and possible burns.
Inhalation:
Irritation may lead to chemical pneumonitis and pulmonary edema.
Causes severe irritation of upper respiratory tract with coughing,
burns, breathing difficulty, and possible coma. May cause lung
damage.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis. May cause lung damage.
**** 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. Discard contaminated clothing in a manner which limits
further exposure.
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. Dusts at sufficient concentrations can form
explosive mixtures with air. Combustion generates toxic fumes. During
a fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Water Reactive. Material will react with
water and may release a flammable and/or toxic gas. Use water spray
to keep fire-exposed containers cool. May ignite or explode on
contact with steam or moist air. Containers may explode when heated.
Extinguishing Media:
DO NOT USE WATER! Do NOT get water inside containers. Contact
professional fire-fighters immediately. Cool containers with
flooding quantities of water until well after fire is out. For small
fires, use dry chemical, soda ash, lime or sand. For large fires,
use dry sand, dry chemical, soda ash or lime or withdraw from area
and let fire burn.
**** 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. Do not get water inside containers.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Do not allow water
to get into the container because of violent reaction. Minimize dust
generation and accumulation. Keep container tightly closed. Do not
get on skin or in eyes. Do not ingest or inhale. Do not allow
contact with water. Keep from contact with moist air and steam.
Storage:
Keep from contact with oxidizing materials. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from water. Store protected from moisture.
**** 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 ventilation to keep airborne
concentrations low.
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 prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Always use
a NIOSH or European Standard EN 149 approved
respirator when necessary.
