PHOSPHORUS PENTASULFIDE

Phosphorus pentasulfide is a poison via ingestion and inhalation; it is a severe eye and skin irritant. Irritation is due to its decomposition products; it is rapidly hydrolyzed, in the presence of moisture, to phosphoric acid and hydrogen sulfide.

The following information is for PHOSPHORIC ACID:

Phosphoric acid causes irritation of eyes, skin, and the respiratory tract. When ingested, it can produce nausea, vomiting, abdominal pain, bloody diarrhea, acidosis, shock, and irritation or burns of the oropharyngeal mucosa, esophagus, and stomach.
When heated to decomposition, oxides of phosphorus are released. There is no evidence that phosphorus poisoning can occur from exposure to phosphoric acid.

Phosphoric acid may react with impurities in metal and release PHOSPHINE GAS.

The following information is for HYDROGEN SULFIDE:

Hydrogen sulfide is a highly toxic, flammable, colorless gas (ACGIH-TLV: 10 ppm) produced by decaying organic matter and has a characteristic odor of rotten egg at low concentrations however, the sense of smell is paralyzed at levels above 50 to 150 ppm.
Exposure to concentrations of 250 ppm causes irritation of mucous membranes, bronchitis and pulmonary edema.
At 500 ppm, symptoms include headache, nausea, weakness, disorientation and coma.
Exposure to higher concentrations can result in immediate death. The mortality rate is in the range of 6%. Characteristic of exposure is the rapid knock down of patients exposed.
Other findings include respiratory depression, tremors, blurred vision, cyanosis, convulsions, and tachycardia.

POTENTIAL HEALTH HAZARDS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004)

Highly toxic: contact with water produces toxic gas, may be fatal if inhaled.
Inhalation or contact with vapors, substance, or decomposition products may cause severe injury or death.
May produce corrosive solutions on contact with water.
Fire will produce irritating, corrosive and/or toxic gases.
Runoff from fire control may cause pollution.

SUMMARY

FIRST AID - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004)

Move victim to fresh air.
Call 911 or emergency medical service.
Give artificial respiration if victim is not breathing.
Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes.
In case of contact with substance, wipe from skin immediately; flush skin or eyes with running water for at least 20 minutes.
Keep victim warm and quiet.
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.

FIRST AID

INHALATION EXPOSURE

INHALATION: Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with an inhaled beta2-adrenergic agonist. Consider systemic corticosteroids in patients with significant bronchospasm.
SEIZURES: Administer a benzodiazepine; DIAZEPAM (ADULT: 5 to 10 mg IV initially; repeat every 5 to 20 minutes as needed. CHILD: 0.1 to 0.5 mg/kg IV over 2 to 5 minutes; up to a maximum of 10 mg/dose. May repeat dose every 5 to 10 minutes as needed) or LORAZEPAM (ADULT: 2 to 4 mg IV initially; repeat every 5 to 10 minutes as needed, if seizures persist. CHILD: 0.05 to 0.1 mg/kg IV over 2 to 5 minutes, up to a maximum of 4 mg/dose; may repeat in 5 to 15 minutes as needed, if seizures continue).

Consider phenobarbital or propofol if seizures recur after diazepam 30 mg (adults) or 10 mg (children greater than 5 years).
Monitor for hypotension, dysrhythmias, respiratory depression, and need for endotracheal intubation. Evaluate for hypoglycemia, electrolyte disturbances, and hypoxia.

NITRITE THERAPY: IV sodium nitrite may be beneficial by forming sulfmethemoglobin, thus removing sulfide from combination in tissue. Do NOT use sodium thiosulfate. The antidotal efficacy of nitrite therapy is controversial but is recommended until further studies are available.
SODIUM NITRITE: Adult: 10 mL (300 mg) of a 3% solution IV at a rate of 2.5 to 5 mL/minute; Child (with normal hemoglobin concentration): 0.2 mL/kg (6 mg/kg) of a 3% solution IV at a rate of 2.5 to 5 mL/minute, not to exceed 10 mL (300 mg).
Repeat one-half of initial sodium nitrite dose one-half hour later if there is inadequate clinical response. Calculate pediatric doses precisely to avoid potentially life-threatening methemoglobinemia. Use with caution if carbon monoxide poisoning is also suspected. Monitor blood pressure carefully. Reduce nitrite administration rate if hypotension occurs.
ACUTE LUNG INJURY: Maintain ventilation and oxygenation and evaluate with frequent arterial blood gases and/or pulse oximetry monitoring. Early use of PEEP and mechanical ventilation may be needed.

DERMAL EXPOSURE

DECONTAMINATION: Remove contaminated clothing and jewelry and place them in plastic bags. Wash exposed areas with soap and water for 10 to 15 minutes with gentle sponging to avoid skin breakdown. A physician may need to examine the area if irritation or pain persists (Burgess et al, 1999).

EYE EXPOSURE

DECONTAMINATION: Remove contact lenses and irrigate exposed eyes with copious amounts of room temperature 0.9% saline or water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist after 15 minutes of irrigation, the patient should be seen in a healthcare facility.

ORAL EXPOSURE

Do not induce emesis, as further caustic injury to the esophagus may occur. Immediate dilution with milk or water might be beneficial. Administer IV sodium bicarbonate to correct acidosis and replace calcium losses if necessary.
DILUTION: If no respiratory compromise is present, administer milk or water as soon as possible after ingestion. Dilution may only be helpful if performed in the first seconds to minutes after ingestion. The ideal amount is unknown; no more than 8 ounces (240 mL) in adults and 4 ounces (120 mL) in children is recommended to minimize the risk of vomiting.
Patients with suspected gastrointestinal tract irritation or burns should be kept NPO. Esophagoscopy should be considered to determine the extent of injury. Surgical consultation and intervention could be needed if bleeding or perforation occur.
If coma develops, assure airway patency, adequate respiration, and oxygenation.
Correct acidosis with intravenous sodium bicarbonate. Replace calcium losses as necessary.
Hemodialysis might be considered if serious, symptomatic hyperphosphatemia occurs.
SEIZURES: Administer a benzodiazepine; DIAZEPAM (ADULT: 5 to 10 mg IV initially; repeat every 5 to 20 minutes as needed. CHILD: 0.1 to 0.5 mg/kg IV over 2 to 5 minutes; up to a maximum of 10 mg/dose. May repeat dose every 5 to 10 minutes as needed) or LORAZEPAM (ADULT: 2 to 4 mg IV initially; repeat every 5 to 10 minutes as needed, if seizures persist. CHILD: 0.05 to 0.1 mg/kg IV over 2 to 5 minutes, up to a maximum of 4 mg/dose; may repeat in 5 to 15 minutes as needed, if seizures continue).

Consider phenobarbital or propofol if seizures recur after diazepam 30 mg (adults) or 10 mg (children greater than 5 years).
Monitor for hypotension, dysrhythmias, respiratory depression, and need for endotracheal intubation. Evaluate for hypoglycemia, electrolyte disturbances, and hypoxia.

EVACUATION PROCEDURES

SUMMARY

Initial Isolation and Protective Action Distances (ERG, 2004)

Data presented from the Emergency Response Guidebook Table of Initial Isolation and Protective Action Distances are for use when a spill has occurred and there is no fire. If there is a fire, or if a fire is involved, evacuation information presented under FIRE - PUBLIC SAFETY EVACUATION DISTANCES should be used.
Generally, a small spill is one that involves a single, small package such as a drum containing up to approximately 200 liters, a small cylinder, or a small leak from a large package. A large spill is one that involves a spill from a large package, or multiple spills from many small packages.
Suggested distances to protect from vapors of toxic-by-inhalation and/or water-reactive materials during the first 30 minutes following the spill.

CONTAINMENT/WASTE TREATMENT OPTIONS

SUMMARY

SPILL OR LEAK PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004)
- Fully encapsulating, vapor protective clothing should be worn for spills and leaks with no fire.
- ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
- Do not touch or walk through spilled material.
- Stop leak if you can do it without risk.
- DO NOT GET WATER on spilled substance or inside containers.
- Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material.
- FOR CHLOROSILANES, use AFFF alcohol-resistant medium expansion foam to reduce vapors.
POWDER SPILL PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004)
- Cover powder spill with plastic sheet or tarp to minimize spreading and keep powder dry.
- DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST.
RECOMMENDED PROTECTIVE CLOTHING - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004)
- 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.
At the time of this review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices (HSDB , 1993).
Generators of waste equal to or greater than 100 kg/month containing phosphorus pentasulfide, US Environmental Protection Agency hazardous waste number U189, must conform with EPA regulations in storage, transportation, treatment and disposal of such wastes (40 CFR 260-270) (HSDB , 1993).
ENVIRONMENTAL CONSIDERATIONS - LAND SPILL (AAR, 1987)
- Dig a pit, pond, lagoon, or holding area to contain liquid or solid material.
- Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water.
ENVIRONMENTAL CONSIDERATIONS - WATER SPILL (AAR, 1987)
- Neutralize with agricultural lime, crushed limestone, or sodium bicarbonate.
Phosphorus pentasulfide is a good candidate for rotary kiln incineration and fluidized bed incineration (HSDB , 1993).

SMALL LEAK/SPILL

SMALL SPILL PRECAUTIONS - EMERGENCY RESPONSE GUIDEBOOK, GUIDE 139 (ERG, 2004)
- Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain.
- Dike for later disposal; do not apply water unless directed to do so.
