acrid, pungent

Heat of solution: -72 Btu/lb= -40 cal/g= -1.7x10+5 J/kg

Fumes in air. Reacts with water, including moisture in air or soil, to liberate heat and hydrochloric acid [Merck, 11th ed. 1989].

Acyl Halides, Sulfonyl Halides, and Chloroformates

Water-Reactive

BENZENE PHOSPHORUS DICHLORIDE is incompatible with water, with bases (including amines), with strong oxidizing agents, and with alcohols. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

Reactivity with water: Reacts vigorously to form hydrogen chloride (hydrochloric acid).

Special Hazards of Combustion Products: Toxic fumes include oxides of phosphorus and hydrogen chloride. Behavior in Fire: Containers may rupture. Hot liquid is spontaneously flammable because of presence of dissolved phosphorus. (USCG, 1999)|Corrosives, Reactive - 1st degree

Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above. FIRE: If tank, rail car or tank truck 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, 2016)

Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]: Fully encapsulating, vapor-protective clothing should be worn for spills and leaks with no fire. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Use water spray to reduce vapors; do not put water directly on leak, spill area or inside container. Keep combustibles (wood, paper, oil, etc.) away from spilled material. SMALL SPILL: Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. Use clean, non-sparking tools to collect material and place it into loosely covered plastic containers for later disposal. Prevent entry into waterways, sewers, basements or confined areas.

FLAMMABLE.

Large amounts of water.

Containers may rupture. Hot liquid is spontaneously flammable because of presence of dissolved phosphorus.

/GUIDE 137: SUBSTANCES - WATER-REACTIVE - CORROSIVE/ Fire or Explosion: EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily. May ignite combustibles (wood, paper, oil, clothing, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Flammable/toxic gases may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. Substance may be transported in a molten form.|/GUIDE 137: SUBSTANCES - WATER-REACTIVE - CORROSIVE/ Health: CORROSIVE and/or TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire will produce irritating, corrosive and/or toxic gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution.|/GUIDE 137: SUBSTANCES - WATER-REACTIVE - CORROSIVE/ Public Safety: CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover. As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate enclosed areas.|/GUIDE 137: SUBSTANCES - WATER-REACTIVE - CORROSIVE/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.|For more DOT Emergency Guidelines (Complete) data for PHENYL PHOSPHORUS DICHLORIDE (8 total), please visit the HSDB record page.

...CORROSIVE TO SKIN & TISSUE.

Inhalation causes irritation of nose and throat; pulmonary edema may develop following severe exposures. Contact with skin or eyes causes severe burns. Ingestion causes severe burns of mouth and stomach. (USCG, 1999)

Get medical attention following all exposures to this compound. INHALATION: remove to fresh air; if breathing has stopped, start mouth-to-mouth resuscitation. EYES: flush with water for at least 15 min.; do not use oils or ointments. SKIN: flush with water; wash with soap and water. INGESTION: give large amounts of milk or water; do NOT induce vomiting; if vomiting does occur, give milk or beaten eggs at one-hour intervals. (USCG, 1999)
