3. HAZARDS IDENTIFICATION

Appearance: white crystals. Warning! Irritant. The toxicological properties of this material have

not been fully investigated. May cause respiratory and digestive tract irritation. Causes eye

irritation. May cause skin irritation. Metabolized to cyanide in the body, which may cause

headache, dizziness, weakness, unconsciousness, convulsions, coma and possible death.

Target Organs: No data found.

Potential Health Effects

Eye: Causes eye irritation. May cause chemical conjunctivitis.

Skin: May cause skin irritation. May be metabolized to cyanide which in turn acts by inhibiting

cytochrome oxidase impairing cellular respiration.

Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The

toxicological properties of this substance have not been fully investigated. Metabolism may

release cyanide, which may result in headache, dizziness, weakness, collapse,

unconsciousness and possible death.

Inhalation: May cause respiratory tract irritation. The toxicological properties of this substance

have not been fully investigated. Can produce delayed pulmonary edema. May be metabolized

to cyanide which in turns act by inhibiting cytochrome oxidase impairing cellular respiration.

Chronic: May be metabolized to cyanide which in turn acts by inhibiting cytochrome oxidase

impairing cellular respiration. Effects may be delayed.

4. FIRST AID MEASURES

Inhalation

Remove to fresh air. If breathing is difficult give oxygen and seek medical attention.

Eye Contact

Flush with copious amounts of water for at least 15 minutes. If irritation persists, seek medical

attention.



Skin Contact

Remove contaminated clothing. Wash affected area with soap and water. Rinse thoroughly. If

irritation persists or other symptoms are observed, seek medical advice.

Ingestion

Rinse out mouth and drink lots of water. Seek medical attention and show physician the

container details.



5. FIRE FIGHTING MEASURES

Extiguishing Medium

Use fire fighting measures which suit the environment and take into account other materials

which may be involved. In general, water-based extinguishers should not be used for fires

involving organic materials. Use dry chemical, sandy soil, chemical foam or carbon dioxide.

Protective Equipment

Wear impervious protective clothing, rubber gloves, chemical safety goggles or filtering gas

mask.

Hazardous Products of Combustion May Include:

carbon monoxide, carbon dioxide, hydrogen chloride (hydrochloric acid), oxides of nitrogen, nitric

acid, hydrogen cyanide.



6. ACCIDENTAL RELEASE MEASURES

Personal Protection

Avoid inhalation or contact of spilled material with skin or clothing. Wear protective equipment

including rubber gloves, and eye protection. Keep unprotected persons away.

Environmental Protection

Take precautions to ensure product does not contaminate the ground or enter the drainage

system.

Collection

Mix with vermiculite or proprietary absorbent material and transfer to sealed containers for

disposal.



7. HANDLING AND STORAGE

Handling

Chemicals should be used only by those trained in handling potentially hazardous materials.

Rubber gloves, eye protection and protective clothing should be worn. Operations should be

carried out in an efficient fume hood or equivalent system.

Storage

Store in a cool, well-ventilated area. Keep away from ignition sources, heat and flame, store in a

tightly closed container, incompatibilities; oxidants and food.



8. EXPOSURE CONTROLS AND PERSONAL PROTECTION

Respiratory

Avoid inhalation of product. Handle in an efficient fume hood or equivalent system.

Eye

Avoid eye contact. Wear safety spectacles, goggles or, for larger quantities, a full face mask.

Hands and Body

Irritant product. Avoid skin contact. Wear rubber gloves, protective clothing and, for larger

quantities, full arm, body and face protection. Wash hands thoroughly after handling.
