**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Causes burns.Corrosive.
Potential Health Effects
Eye:
May cause irreversible eye injury. Contact with liquid is
corrosive to the eyes and causes severe burns.
Skin:
Contact with liquid is corrosive and causes severe burns and
ulceration.
Ingestion:
Causes severe pain, nausea, vomiting, diarrhea, and shock. May cause
hemorrhaging of the digestive tract. May cause corrosion and
permanent tissue destruction of the esophagus and digestive tract.
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.
Chronic:
Prolonged inhalation may cause respiratory tract inflammation and
lung damage.
**** 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.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
soap and 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 to fresh air
immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
During a fire, irritating and highly toxic gases may be generated by
thermal decomposition or combustion. Use water spray to keep
fire-exposed containers cool. 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. Containers may explode if exposed to fire.
Extinguishing Media:
For small fires, use water spray, dry chemical, carbon dioxide or
chemical foam. Cool containers with flooding quantities of water
until well after fire is out.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Cover with sand, dry lime or soda ash and place in
a closed container for disposal. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Keep container tightly closed. Do not get on skin or in eyes. Do not
ingest or inhale. Discard contaminated shoes.
Storage:
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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
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 gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29CFR
1910.134 or European Standard EN 149. Always use a
NIOSH or European Standard EN 149 approved respirator
when necessary.

Stable under normal temperatures and pressures.
Conditions to Avoid:
Incompatible materials, excess heat, temperatures above 100C, bases.
Incompatibilities with Other Materials:
Reacts violently with oxicdizing agents and mercury (II) nitrate;
reacts explosively with mercury (II) oxide. Causes exothermic
reations with aldehydes, amines, amides, alcohols and glycols,
azo-compounds, carbamates, esters, caustics, phenols and cresols,
ketones, organophosphates, epoxides, explosives, combustible
materials, unsaturated halides, and organic peroxides. Forms
flammable gases with sulfides, mercaptans, cyanides, and aldehydes.

peroxides, and halogenated organics. Hot, dilute phosphoric acid
reacts with nickel carbonate to form trinickel orthphosphate.
Mixtures with nitromethane are explosive.
Hazardous Decomposition Products:
Phosphine, oxides of phosphorus, phosphoric acid.
