The Hazard fields include special hazard alerts, air and water reactions, fire hazards, health hazards, a reactivity profile, and details about reactive groups assignments and potentially incompatible absorbents. The information in CAMEO Chemicals comes from a variety of data sources.
Reactivity Alerts
Air & Water Reactions
Water soluble.
Fire Hazard
Behavior in Fire: At fire temperature decomposes to emit highly toxic and irritating phosphorus oxides. (USCG, 1999)
Health Hazard
INHALATION: Will produce local irritation in the respiratory tract. A burning sensation in the nose and throat, as well as coughing (and in high concentrations, choking) may be noted. May cause lung irritation. EYES: Immediate and severe pain followed by conjuctival edema and corneal clouding. Cataracts may form. SKIN: Immediate local reactions, including reddening, itching and irritation, followed by loss of surface layers of the skin. INGESTION: Severe tissue damage to all portions of the gastrointestinal tract. Symptoms include pain and burning wherever contact is made. Nausea, vomiting, cramps, and diarrhea may occur. Tissue corrosion and ulceration may result if untreated. (USCG, 1999)
Reactivity Profile
SODIUM PHOSPHATE, [TRIBASIC] corrodes aluminum and zinc [Handling Chemicals Safely 1980 p. 947]. Reacts when heated above about 84°C with aqueous solutions of reducing sugars other than sucrose, to evolve toxic levels of carbon monoxide [Bretherick, 5th Ed., 1995].
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Response Recommendations

The Response Recommendation fields include isolation and evacuation distances, as well as recommendations for firefighting, non-fire response, protective clothing, and first aid. The information in CAMEO Chemicals comes from a variety of data sources.
Isolation and Evacuation
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

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 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

SMALL FIRE: Dry chemical, CO2 or water spray.

LARGE FIRE: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)
Non-Fire Response
Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. (ERG, 2016)
Protective Clothing
Rubber gloves and boots, safety goggles or face mask, hooded suit, and respirator with approved canister, or a self-contained breathing apparatus. (USCG, 1999)
DuPont Tychem® Suit Fabrics
No information available.
First Aid
Get medical aid.

INHALATION: Remove from exposure. If needed, give artificial respiration.

EYES: Wash with running water for 15 min. Continue irrigation for additional 15 min. if physician is (USCG, 1999)
