| Common Names: - Elemental phosphorus
- Phosphorus
- Yellow phosphorus
|
 |
- APPEARANCE: White to yellow transparent, waxy crystalline solid. Turns dark on exposure to light.
- DESCRIPTION: White phosphorus is a toxic substance produced from phosphate-containing rocks. White phosphorus is used industrially to manufacture chemicals used in fertilizers, food additives, and cleaning compounds. It has been used in the past as a pesticide and in fireworks. It is used by the military in various types of ammunition as an incendiary agent (because it spontaneously catches fire in air) and as a smoke agent (because it produces clouds of irritating white smoke). It has a match-like or garlic-like, acrid odor, but odor should not be depended on for detection of white phosphorus.
- METHODS OF DISSEMINATION:
- Indoor Air: White phosphorus can be released into indoor air as smoke.
- Water: White phosphorus can be used to contaminate water.
- Food: White phosphorus cannot be used to contaminate food.
- Outdoor Air: White phosphorus can enter outdoor air as smoke.
- Agricultural: If white phosphorus is released as smoke, it is unlikely to contaminate agricultural products; however, particles of white phosphorus that do not react with air may contaminate agricultural products.
- ROUTES OF EXPOSURE: White phosphorus can be absorbed into the body by inhalation, ingestion, or skin contact. It is unknown whether systemic exposure can occur from eye contact.

- CHEMICAL DANGERS:
- Phosphorus spontaneously ignites on contact with air, producing toxic fumes (phosphorus oxides).
- Phosphorus reacts violently with oxidants, halogens, some metals, nitrites, sulfur, and many other compounds, causing a fire and explosion hazard.
- Phosphorus reacts with strong bases to produce toxic phosphine gas.
- EXPLOSION HAZARDS:
- Phosphorus reacts violently with oxidants, halogens, some metals, nitrites, sulfur, and many other compounds, causing an explosion hazard.
- Upper and lower explosive (flammable) limits in air are not available for white phosphorus.
- FIRE FIGHTING INFORMATION:
- White phosphorus is extremely flammable.
- Phosphorus will spontaneously ignite if exposed to air.
- Phosphorus ignites at approximately 86°F (30°C) in air; the ignition temperature is higher when the air is dry.
- Phosphorus reacts violently with oxidants, halogens, some metals, nitrites, sulfur, and many other compounds, causing a fire hazard.
- The agent burns rapidly, releasing dense, white irritating fumes.
- The agent may be transported in a molten form.
- The agent may re-ignite after a fire is extinguished.
- For small fires, use cold water spray, wet sand, or wet earth.
- For large fires, use cold water spray or fog. Do not scatter spilled material with high-pressure cold water streams. Move containers from the fire area if it is possible to do so without risk to personnel.
- For fire involving tanks or car/trailer loads, fight the fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of cold water until well after the fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tanks. Always stay away from tanks engulfed in fire.
- Run-off from fire control may be corrosive and/or toxic, and it may cause pollution.
- If the situation allows, control and properly dispose of run-off (effluent).
- INITIAL ISOLATION AND PROTECTIVE ACTION DISTANCES:
- If a tank, rail car, or tank truck is involved in a fire, isolate it for 0.5 mi (800 m) in all directions; also consider initial evacuation for 0.5 mi (800 m) in all directions.
- This agent is not included in the DOT ERG 2004 Table of Initial Isolation and Protective Action Distances.
- In the DOT ERG 2004 orange-bordered section of the guidebook, there are public safety recommendations to isolate a white phosphorus (Guide 136) spill or leak area immediately for at least 150 ft (50 m) for liquids and 75 ft (25 m) for solids in all directions.

- TIME COURSE: Exposure to white phosphorus may cause immediate burns that heal slowly. Systemic toxicity from white phosphorus exposure is classically divided into 3 phases. The first phase, the gastrointestinal phase, occurs a few minutes to 8 hours following white phosphorus exposure. Shock during this phase may be severe enough to cause death in 24 to 48 hours. The second phase, the asymptomatic phase, follows the first phase and lasts for 8 hours to 3 days. The third phase, the multi-organ failure and central nervous system injury phase, may begin 4 to 8 days after the second phase begins, and may end in death.
- EFFECTS OF SHORT-TERM (LESS THAN 8-HOURS) EXPOSURE: White phosphorus burns in air and causes severe burns upon contact with skin or eyes. White phosphorus smoke will also cause eye and respiratory tract irritation. Other initial adverse health effects are primarily due to gastrointestinal irritation.
- EYE EXPOSURE:
- White phosphorus fumes cause severe irritation and the sensation of a foreign body in the eye. This leads to excessive tear production (lacrimation), spasmodic blinking (blepharospasm), and increased sensitivity to light (photophobia).
- White phosphorus particles are caustic and seriously damaging when in contact with tissues. They cause damage to the cornea, including perforation, inflammation of the interior of the eyeball (endophthalmitis), and abnormal turning out of the eyelid (ectropion).
- INGESTION EXPOSURE:
- Stage 1: Feeling of warmth or burning pain in the throat and abdomen accompanied by feelings of intense thirst; nausea, vomiting (emesis), diarrhea, and severe abdominal pain; garlic odor to the breath, vomitus, and feces; vomitus and feces may glow (luminesce) and are capable of causing burns on contact with skin; death may occur within 24 to 48 hours due to complete cardiovascular collapse.
- INHALATION EXPOSURE:
- Eye and upper respiratory tract irritation are expected.
- Delayed onset of accumulation of fluid in the lungs (pulmonary edema) is possible.
- Whole-body (systemic) effects may also occur.
- See Ingestion Exposure.
- SKIN EXPOSURE:
- White phosphorus causes severely painful, partial (second degree) to full thickness (third degree) burns, which have a characteristic yellow color and garlic-like odor. Smoke may be released from the burn site from the continued burning of white phosphorus or the formation of phosphoric acid.
- White phosphorus is highly fat soluble, and easily absorbed through the skin, possibly causing whole-body (systemic) effects.
- See Ingestion Exposure

- INTRODUCTION: The purpose of decontamination is to make an individual and/or their equipment safe by physically removing toxic substances quickly and effectively. Care should be taken during decontamination, because absorbed agent can be released from clothing and skin as a gas. Your Incident Commander will provide you with decontaminants specific for the agent released or the agent believed to have been released.
- DECONTAMINATION CORRIDOR: The following are recommendations to protect the first responders from the release area:
- Position the decontamination corridor upwind and uphill of the hot zone. The warm zone should include two decontamination corridors. One decontamination corridor is used to enter the warm zone and the other for exiting the warm zone into the cold zone. The decontamination zone for exiting should be upwind and uphill from the zone used to enter.
- Decontamination area workers should wear appropriate PPE. See the PPE section of this card for detailed information.
- A solution of detergent and water (which should have a pH value of at least 8 but should not exceed a pH value of 10.5) should be available for use in decontamination procedures. Soft brushes should be available to remove contamination from the PPE. Labeled, durable 6-mil polyethylene bags should be available for disposal of contaminated PPE.
- INDIVIDUAL DECONTAMINATION: The following methods can be used to decontaminate an individual:
- Decontamination of First Responder:
- Begin washing PPE of the first responder using soap and cool water solution and a soft brush. Always move in a downward motion (from head to toe). Make sure to get into all areas, especially folds in the clothing. Wash and rinse (using cool water) until the contaminant is thoroughly removed.
- Remove PPE by rolling downward (from head to toe) and avoid pulling PPE off over the head. Remove the SCBA after other PPE has been removed.
- Wash PPE down with cool water to remove any white phosphorus particles before placing it into labeled durable 6-mil polyethylene bags.
- Decontamination of Patient/Victim:
- Remove the patient/victim from the contaminated area and into the decontamination corridor.
- Remove all clothing (at least down to their undergarments) and place the clothing in a labeled durable 6-mil polyethylene bag.
- Thoroughly wash and rinse (using cold water) the contaminated skin of the patient/victim using a soap and water solution. Be careful not to break the patient/victim’s skin during the decontamination process, and cover all open wounds.
- Cover the patient/victim to prevent shock and loss of body heat.
- Move the patient/victim to an area where emergency medical treatment can be provided.

- GENERAL INFORMATION: Initial treatment is primarily supportive. In cases of skin or eye exposure, it includes the immediate removal of burning particles of white phosphorus from the patient/victim's eyes or skin. If skin or eyes are contaminated with white phosphorus, cover them with cool wet cloths to avoid re-ignition.
- ANTIDOTE: There is no antidote for white phosphorus toxicity.
- EYE:
- Immediately remove the patient/victim from the source of exposure.
- Immediately wash eyes with large amounts of cool water for at least 15 minutes.
- Keep exposed eyes covered with wet compresses to prevent white phosphorus particles from re-igniting.
- Avoid application of any lipid- or oil-based ointments, which may increase the absorption of white phosphorus.
- Consider application of an eye cage to prevent direct pressure being applied to the eyeball.
- Seek medical attention immediately.
- INGESTION:
- Immediately remove the patient/victim from the source of exposure.
- Ensure that the patient/victim has an unobstructed airway.
- Do not induce vomiting (emesis).
- Monitor heart function and evaluate for low blood pressure (hypotension), abnormal heart rhythms (dysrhythmias), and reduced respiratory function (respiratory depression).
- Evaluate for low blood sugar (hypoglycemia), electrolyte disturbances, and low oxygen levels (hypoxia).
- If evidence of shock or low blood pressure (hypotension) is observed, begin intravenous (IV) fluid administration.
- Seek medical attention immediately.
- INHALATION:
- Immediately remove the patient/victim from the source of exposure.
- Evaluate respiratory function and pulse.
- Ensure that the patient/victim has an unobstructed airway.
- If shortness of breath occurs or breathing is difficult (dyspnea), administer oxygen.
- Assist ventilation as required. Always use a barrier or bag-valve-mask device.
- If breathing has ceased (apnea), provide artificial respiration.
- Monitor for respiratory compromise, respiratory distress, and accumulation of fluid in the lungs (pulmonary edema).
- Monitor the patient/victim for signs of whole-body (systemic) effects and administer symptomatic treatment as necessary.
- Seek medical attention immediately.
- SKIN:
- Immediately remove the patient/victim from the source of exposure.
- See the Decontamination section for patient/victim decontamination procedures.
- Immerse areas of affected skin in cold water or cover them with wet dressings at all times.
- Vigorous irrigation with cold water is the best way to remove white phosphorous embedded in the skin.
- Remove visible particles of white phosphorus while washing with large amounts of cold water or while the area is submerged in cold water.
- The use of cold water is critical, but care should also be taken to guard the patient/victim against hypothermia.
- Immediately place any particles of white phosphorus that are removed into a container of cold water to reduce risk to medical personnel and others.
- Avoid application of any lipid- or oil-based ointments, which may increase the absorption of white phosphorus.
- Monitor the patient/victim for signs of whole-body (systemic) effects.
- If signs of whole-body (systemic) poisoning appear, see the Ingestion section for treatment recommendations.
- Seek medical attention immediately.

- MEDICAL TREATMENT: Hypotension should be treated with IV fluids. Seizures should be treated with benzodiazepines. For ingestion or extensive skin exposure, low blood levels of calcium (hypocalcemia) should be corrected with IV calcium gluconate (adult and child dose: 0.1 to 0.2 mL/kg up to 10 mL/dose of a 10% solution; repeat the dose if necessary) or calcium chloride. Some patient/victims with abnormal heart rhythms may require application of an electric shock (cardioversion) to restore normal heartbeat, plus additional treatment. For skin exposure, visualization of phosphorus particles may be enhanced under an ultraviolet (UV) light source (black light, Wood’s lamp). Phosphorus particles should glow (fluoresce) under UV light. With the exposed areas immersed in cold water (to avoid ignition) carefully remove all visualized phosphorus particles (either loose or imbedded). The use of cold water has the potential to induce hypothermia. Steps should be taken to guard against hypothermia. Particles of phosphorus that are removed should be placed in cold water-filled containers to prevent risk to medical personnel and others. For eye exposure, consultation with an ophthalmologist is required.
- DELAYED EFFECTS OF EXPOSURE: Stage 2: If the patient/victim survives Stage 1, clinical improvement and a symptom-free interval occur for several days.
Stage 3: Nausea, vomiting (bloody; hematemesis), and diarrhea; liver enlargement and tenderness and clinical signs of liver damage; blood vessels become fragile and blood stops clotting properly, resulting in bleeding into the skin, mucous membranes, and various organs; severe kidney damage and failure; seizures, delirium, and coma; cardiovascular collapse; and death may occur within 4 to 8 days.
- EFFECTS OF CHRONIC OR REPEATED EXPOSURE: White phosphorus is not classifiable as a carcinogen. However, it is not suspected to be a carcinogen. It is unknown whether chronic or repeated exposure to white phosphorus increases the risk of reproductive toxicity or developmental toxicity. Chronic industrial inhalation exposure to white phosphorus fumes has resulted in symptoms that include general disability, inflammation of the large airways (bronchitis), anemia, physical wasting and malnutrition (cachexia), and destruction of the jaw bones, which is called "phossy jaw" or "Lucifer's jaw.”

- INCIDENT SITE:
- Consult with the Incident Commander regarding the agent dispersed, dissemination method, level of PPE required, location, geographic complications (if any), and the approximate number of remains.
- Coordinate responsibilities and prepare to enter the scene as part of the evaluation team along with the FBI HazMat Technician, local law enforcement evidence technician, and other relevant personnel.
- Begin tracking remains using waterproof tags.
- RECOVERY AND ON-SITE MORGUE:
- Wear PPE until all remains are deemed free of contamination.
- Establish a preliminary (holding) morgue.
- Gather evidence, and place it in a clearly labeled impervious container. Hand any evidence over to the FBI.
- Remove and tag personal effects.
- Perform a thorough external evaluation and a preliminary identification check.
- See the Decontamination section for decontamination procedures.
- Decontaminate remains before they are removed from the incident site.

- ENVIRONMENT/SPILLAGE DISPOSAL: The following methods can be used to decontaminate the environment/spillage disposal:
- Do not touch or walk through the spilled agent if at all possible. However, if you must, personnel should wear the appropriate PPE during environmental decontamination. See the PPE section of this card for detailed information.
- Keep combustibles (e.g., wood, paper, and oil) away from the spilled agent. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact the spilled agent.
- Do not direct water at the spill or the source of the leak.
- Stop the leak if it is possible to do so without risk to personnel, and turn leaking containers so that gas rather than liquid escapes.
- Prevent entry into waterways, sewers, basements, or confined areas.
- Isolate the area until gas has dispersed.
- Ventilate the area.
- EQUIPMENT: Agents can seep into the crevices of equipment making it dangerous to handle. The following methods can be used to decontaminate equipment:
