Section 3: Hazards Identification

 

Potential Health Effects

Eye: May cause eye irritation. May result in corneal injury.

Skin: May cause skin irritation. Prolonged and/or repeated contact may cause irritation and/or dermatitis.

Ingestion: May be fatal if swallowed. May cause irritation of the digestive tract. May cause liver and kidney damage.

Inhalation: May cause respiratory tract irritation.

Chronic: Prolonged or repeated skin contact may cause dermatitis. May cause liver and kidney damage. Chronic exposure can lead to necrosis of the jaw, or 'phossy-jaw'.

 

Section 4: First Aid Measures

 

SKIN : Wash with soap and water. If burned immerse burned area in water, apply dressings coated in saturated sodium bicarbonate solution as soon as possible. Get medical attention.

 

EYES : Flush eyes with water for at least 15 minutes, lifting upper and lower lids. If irritation occurs, seek medical attention.

 

INHALATION : Move to ventilated area immediately. Give artificial respiration if breathing has stopped. Seek medical attention.

 

INGESTION : Not toxic. ld50 more than 10,000 mg/kg. note that red phosphorous is very different in this regard from yellow / white phosphorous (which is highly toxic) even though they are different forms of the same element, and share the same cas number. if ingested, do not induce vomiting. seek immediate medical assistance.

 

Section 5: Fire and Explosion Data

 

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Containers may explode in the heat of a fire. This material is readily combustible and may ignite if exposed to friction. Flammable solid. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. May re-ignite after fire is extinguished.

Extinguishing Media: For small fires, use dry chemical, sand, water spray, or foam. For large fires, use water spray, fog or regular 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: Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Avoid generating dusty conditions. Cover with sand and place into a closed container for disposal. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.

 

Section 7: Handling and Storage

 

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Store protected from light. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.

Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. Store protected from light.

 

Section 8: Exposure Controls/Personal Protection

 

Engineering Controls: Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.

Conditions to Avoid: Incompatible materials, light, ignition sources, dust generation, excess heat, strong oxidants.

Incompatibilities with Other Materials: Red, white and yellow phosphorus reacts explosively with a large number of compounds and elements. Please refer to NFPA 's Fire Protection guide to Hazardous Materials for details. May explode on contact with oxidizing materials. Produces acrid fumes in air. Can be ignited by friction, static electric discharge, heating and mixing with strong oxidizing agents. Reacts with halogens, halides, sulfur and oxidizing materials.

Hazardous Decomposition Products: Phosphine, oxides of phosphorus, irritating and toxic fumes and gases.

Hazardous Polymerization: Has not been reported.
