The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)

Special Hazards of Combustion Products: Toxic fumes include oxides of phosphorus and hydrogen chloride.

· EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily.

· EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily.

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)

· CORROSIVE and/or TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death.

· CORROSIVE and/or TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death.

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].

/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.

Immediate precautionary measure

Immediate precautionary measure

Self-contained breathing apparatus; acid-type canister mask; goggles and face shield; rubber gloves; protective clothing. (USCG, 1999)

Self-contained breathing apparatus; acid-type canister mask; goggles & face shield; rubber gloves; protective clothing.

· When material is not involved in fire, do not use water on material itself.

· When material is not involved in fire, do not use water on material itself.

SYMPTOMATOLOGY (...INGESTION OR SKIN CONTACT): 1. CORROSION OF MUCOUS MEMBRANES OF MOUTH, THROAT AND ESOPHAGUS, WITH IMMEDIATE PAIN AND DYSPHAGIA. NECROTIC AREAS...GRAYISH WHITE BUT SOON ACQUIRE A BLACKISH DISCOLORATION (YELLOW IN CASE OF NITRIC ACID) & SOMETIMES SHRUNKEN OR WRINKLED TEXTURE... 2. EPIGASTRIC PAIN...MAY BE ASSOC WITH NAUSEA & VOMITING... AT TIMES, GASTRIC HEMORRHAGE MAY BE INTENSE, AND VOMITUS THEN CONTAINS FRESH BLOOD. PROFOUND THIRST. 3. ULCERATION OF ALL MEMBRANES AND TISSUES WITH WHICH THE ACID COMES IN CONTACT. AFTER THE INGESTION OF CONCN MINERAL ACID, THIS CORROSION MAY LEAD WITHIN A FEW HR OR A FEW DAYS TO GASTRIC PERFORATION AND PERITONITIS. 4. CIRCULATORY COLLAPSE WITH CLAMMY SKIN, WEAK & RAPID PULSE, SHALLOW RESP, AND SCANTY URINE. CIRCULATORY EDEMA. /ACIDS/

SYMPTOMATOLOGY.../INGESTION/: 6. LATE ESOPHAGEAL, GASTRIC & PYLORIC STRICTURES & STENOSES, WHICH MAY REQUIRE MAJOR SURGICAL REPAIR, SHOULD BE ANTICIPATED. SIGNS OF OBSTRUCTION COMMONLY APPEAR WITHIN A FEW WK BUT MAY BE DELAYED FOR MONTHS AND EVEN YEARS. PERMANENT SCARS MAY ALSO APPEAR IN THE CORNEA, SKIN AND OROPHARYNX. 7. UNCORRECTED CIRCULATORY COLLAPSE OF SEVERAL HR...MAY LEAD TO RENAL FAILURE & ISCHEMIC LESIONS IN LIVER & HEART. /ACIDS/
