General Description
Black crystalline or amorphous solid resembling graphite. Conducts electricity. Denser than water and insoluble in water. Hence sinks in water. (USCG, 1999)
Hazards
Reactivity Alerts
none
Air & Water Reactions
Stable in air. Does not spontaneously ignite in air (a property of white or yellow phosphorus). Insoluble in water.
Fire Hazard
Excerpt from ERG Guide 133 [Flammable Solids]:
Flammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare-burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished. (ERG, 2024)
Health Hazard
Excerpt from ERG Guide 133 [Flammable Solids]:
Fire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause environmental contamination. (ERG, 2024)
Reactivity Profile
PHOSPHORUS, [BLACK] is a reducing agent. Much less reactive than the allotropic white phosphorus. Reacts strongly with bromine trifluoride. [Mellor 2:113. 1946-47]. Explodes on contact with bromoazide.
Belongs to the Following Reactive Group(s)

Response Recommendations
Isolation and Evacuation
Excerpt from ERG Guide 133 [Flammable Solids]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 25 meters (75 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet).
FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)
Firefighting
Excerpt from ERG Guide 133 [Flammable Solids]:
SMALL FIRE: Dry chemical, CO2, sand, earth, water spray or regular foam.
LARGE FIRE: Water spray, fog or regular foam. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING METAL PIGMENTS OR PASTES (E.G. "ALUMINUM PASTE"): Aluminum Paste fires should be treated as a combustible metal fire. Use DRY sand, graphite powder, dry sodium chloride-based extinguishers or class D extinguishers. Also, see ERG Guide 170.
FIRE INVOLVING TANKS, RAIL TANK CARS OR HIGHWAY TANKS: Cool containers with flooding quantities of water until well after fire is out. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. (ERG, 2024)
Non-Fire Response
Excerpt from ERG Guide 133 [Flammable Solids]:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. Do not touch or walk through spilled material.
SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.
LARGE SPILL: Wet down with water and dike for later disposal. Prevent entry into waterways, sewers, basements or confined areas. (ERG, 2024)
Protective Clothing
Excerpt from ERG Guide 133 [Flammable Solids]:
Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. (ERG, 2024)

First Aid
Excerpt from ERG Guide 133 [Flammable Solids]:
Refer to the "General First Aid" section. Specific First Aid: Removal of solidified molten material from skin requires medical assistance. (ERG, 2024)
