General Description
A yellow crystalline solid high explosive. Toxic by ingestion and skin absorption. A skin irritant. Will explode if heated above 370°F. Used as a detonating explosive. The primary hazard is the blast of an instantaneous explosion and not flying projectiles and fragments.
Hazards
Reactivity Alerts
- Explosive
- Strong Oxidizing Agent
Air & Water Reactions
No rapid reaction with air. No rapid reaction with water.
Fire Hazard
Excerpt from ERG Guide 112 [Explosives - Division 1.1, 1.2, 1.3 or 1.5]:
MAY EXPLODE AND THROW FRAGMENTS 1600 METERS (1 MILE) OR MORE IF FIRE REACHES CARGO. (ERG, 2024)
Health Hazard
Excerpt from NIOSH Pocket Guide for Tetryl:
Exposure Routes: Inhalation, skin absorption, ingestion, skin and/or eye contact
Symptoms: Sensitization dermatitis, itch, erythema (skin redness); edema on nasal folds, cheeks, neck; keratitis (inflammation of the cornea); sneezing; anemia; cough, coryza; irritability; malaise (vague feeling of discomfort), headache, lassitude (weakness, exhaustion), insomnia; nausea, vomiting; liver, kidney damage
Target Organs: Eyes, skin, respiratory system, central nervous system, liver, kidneys (NIOSH, 2024)
Reactivity Profile
During the measurement of the shock sensitivity of a mixture containing hydrazine, a drop of the hydrazine mixture fell on a tetryl explosive. The tetryl immediately burst into flames (ASESB 105).
Belongs to the Following Reactive Group(s)

Response Recommendations
Isolation and Evacuation
Excerpt from ERG Guide 112 [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, 2024)
Firefighting
Excerpt from ERG Guide 112 [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, 2024)
Non-Fire Response
Excerpt from ERG Guide 112 [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, 2024)
Protective Clothing
Excerpt from NIOSH Pocket Guide for Tetryl:
Skin: PREVENT SKIN CONTACT - Wear appropriate personal protective clothing to prevent skin contact.
Eyes: PREVENT EYE CONTACT - Wear appropriate eye protection to prevent eye contact.
Wash skin:
� WHEN CONTAMINATED - The worker should immediately wash the skin when it becomes contaminated.
� DAILY - The worker should wash daily at the end of each work shift, and prior to eating, drinking, smoking, etc.
Remove: WHEN WET OR CONTAMINATED - Work clothing that becomes wet or significantly contaminated should be removed and replaced.
Change: DAILY - Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises. (NIOSH, 2024)

First Aid
Excerpt from NIOSH Pocket Guide for Tetryl:
Eye: IRRIGATE IMMEDIATELY - If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately.
Skin: SOAP WASH PROMPTLY - If this chemical contacts the skin, promptly wash the contaminated skin with soap and water. If this chemical penetrates the clothing, promptly remove the clothing and wash the skin with soap and water. Get medical attention promptly.
Breathing: RESPIRATORY SUPPORT - If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. If breathing has stopped, perform artificial respiration. Keep the affected person warm and at rest. Get medical attention as soon as possible.
Swallow: MEDICAL ATTENTION IMMEDIATELY - If this chemical has been swallowed, get medical attention immediately. (NIOSH, 2024)
