General Description
A thick slurry of white crystals. The pure compound is a dangerous explosive, particularly when dry. Addition of water or phlegmatizer reduces sensitivity to shock and heat. May explode under exposure to heat or fire. Primary hazard is blast of an instantaneous explosion, not flying projectiles or fragments.

Fire Hazard
Flash point data for this compound are not available. It is probably combustible. (NTP, 1992)
Health Hazard
SYMPTOMS: Symptoms of exposure to this compound may include a decrease in blood pressure, dyspnea, convulsions, cyanosis, headache, dizziness, postural hypotension, weakness, nausea, vomiting, pallor, sweating, collapse, rashes, coma, respiratory paralysis and formation of methemoglobin.

ACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits highly toxic fumes. (NTP, 1992)
Reactivity Profile
PENTAERYTHRITE TETRANITRATE is a high explosive. An oxidizing agent. May begin a vigorous reaction that culminates in a detonation if mixed with reducing agents, including hydrides, sulfides and nitrides. Emits highly toxic nitrogen oxide fumes on decomposition.
Belongs to the Following Reactive Group(s)

Response Recommendations

Isolation and Evacuation
Excerpt from 112 Polymerizable warning [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area immediately for at least 500 meters (1/3 mile) in all directions.

LARGE SPILL: Consider initial evacuation for 800 meters (1/2 mile) in all directions.

FIRE: If rail car or trailer is involved in a fire, ISOLATE for 1600 meters (1 mile) in all directions; also, initiate evacuation including emergency responders for 1600 meters (1 mile) in all directions. (ERG, 2020)
Firefighting
Excerpt from 112 Polymerizable warning [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

CARGO FIRE: DO NOT fight fire when fire reaches cargo! Cargo may EXPLODE! Stop all traffic and clear the area for at least 1600 meters (1 mile) in all directions and let burn. Do not move cargo or vehicle if cargo has been exposed to heat.

TIRE OR VEHICLE FIRE: Use plenty of water - FLOOD it! If water is not available, use CO2, dry chemical or dirt. If possible, and WITHOUT RISK, use unmanned master stream devices or monitor nozzles from maximum distance to prevent fire from spreading to cargo area. Pay special attention to tire fires as re-ignition may occur. Stand by, at a safe distance, with extinguisher ready for possible re-ignition. (ERG, 2020)
Non-Fire Response
Excerpt from 112 Polymerizable warning [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. DO NOT OPERATE RADIO TRANSMITTERS WITHIN 100 METERS (330 FEET) OF ELECTRIC DETONATORS. DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST. (ERG, 2020)
Protective Clothing
Excerpt from ERG Guide 112 [Explosives* - Division 1.1, 1.2, 1.3 or 1.5]:

Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing provides thermal protection but only limited chemical protection. (ERG, 2020)

First Aid
EYES: Check for contact lenses and remove them at once if present. You should then immediately flush eyes with water for 15 minutes. Do not use oil or ointment in eyes. Arrange immediate transportation to a medical facility.

SKIN: You should remove all contaminated clothing and flood skin with water. Wash all affected skin areas thoroughly with soap and water. If symptoms persist or develop, seek medical attention.

INHALATION: If any of your laboratory personnel should inhale this chemical, remove them at once to open air and arrange for immediate transportation to a medical facility.

INGESTION: If the exposed person is convulsing or unconscious, do not attempt first aid. Transport immediately to a hospital emergency room or poison control center. If the victim is conscious, DO NOT INDUCE VOMITING. Transport to a medical facility. (NTP, 1992)
