Acids, Strong Non-oxidizing

Water-Reactive

PHOSPHORUS PENTACHLORIDE is a lightly yellow, fuming crystalline material, highly caustic, corrosive and toxic. Flammable by chemical reaction. Violent exothermic reaction with water or steam. When heated to decomposition it emits highly toxic fumes of chlorides and oxides of phosphorus. Explosive reaction with alkaline metals (sodium, potassium), urea. Ignites on contact with fluorine. Violent reaction with aluminum, chlorine trioxide, hydroxylamine, magnesium oxide, nitrobenzene, phosphorus(III) oxide, potassium. Carbamates form explosive products [Bretherick, 5th ed., 1995, p. 1360]. Reaction with the mixture of chlorine and chlorine dioxide causes explosion [Mellor, 1941, vol. 2, p. 281; 1940, vol. 8, p. 1013].

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: See ERG Table 1 - Initial Isolation and Protective Action Distances on the UN/NA 1806 datasheet. 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. (ERG, 2016)

Skin: Wear appropriate personal protective clothing to prevent skin contact. Eyes: Wear appropriate eye protection to prevent eye contact. Wash skin: The worker should immediately wash the skin when it becomes contaminated. Remove: Work clothing that becomes wet or significantly contaminated should be removed and replaced. Change: Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premise. Provide: Eyewash fountains should be provided in areas where there is any possibility that workers could be exposed to the substance; this is irrespective of the recommendation involving the wearing of eye protection. Facilities for quickly drenching the body should be provided within the immediate work area for emergency use where there is a possibility of exposure. [Note: It is intended that these facilities provide a sufficient quantity or flow of water to quickly remove the substance from any body areas likely to be exposed. The actual determination of what constitutes an adequate quick drench facility depends on the specific circumstances. In certain instances, a deluge shower should be readily available, whereas in others, the availability of water from a sink or hose could be considered adequate.] (NIOSH, 2016)|Personal protective equipment to be worn in any case of reasonable possibility of contact...incl chemical goggles & gloves.

Treatment for exposure to the chloro cmpds consists of removal from the source, removal of any clothing contaminated with the cmpds, and observation and treatment of any respiratory complication such as bronchospasm and pulmonary edema that may arise. Ocular splash or injury requires copious irrigation and examination with slit lamp to assess degree of injury, and ophthalmologic consultation if indicated. /Unspecified phosphorus cmpds/|Treatment of acute phosphorus exposure should consist of initial stabilization with attention to airway/respiratory distress and shock, if present. Personnel involved in treatment of poisoned victims must adhere to adequate precautions to protect themselves as well. Protective respiratory gear should be worn in circumstances where continued exposure to gas, vapors, or fumes may occur. Gown and gloves need to be worn, as rescuers or health personnel may come in contact with particles causing burns and toxicity. Treatment of burns involves application of a 2-3% soln of copper sulfate, which will cause formation of an insoluble salt, thereby preventing further absorption and damage. This treatment, however, has been questioned by some authors, due to potential toxicity with copper. Alternatively, a 2-3% silver nitrate soln has been used on the theory that silver granules precipitating on the skin will prevent absorption of the phosphorus cmpd ... /Unspecified phosphorus cmpds/|Oral exposure should be treated with gastric decontamination. Use of oils will promote absorption of phosphorus from the GI tract and should be avoided. Hypovolemia secondary to nausea, vomiting, and diarrhea should be aggressively treated with crystalloid until normovolemia is restored. Close attention should be paid to hepatic and renal function. Adequate urine output should be maintained, and sequelae of liver failure such as coagulopathies and nutritional deficiency should be treated as the need arises with the appropriate measures. /Unspecified phosphorus cmpds/|/SRP:/ Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration.
