NFPA 704
General Description
A pale yellow, viscous liquid that is slightly soluble in water and more dense than water. Sensitive to shock and heat. May explode under prolonged exposure to fire or heat. Primary hazard is the blast of an instantaneous explosion and not flying fragment or projectiles. Used medicinally.
Hazards
Reactivity Alerts
- Highly Flammable
- Explosive
- Strong Oxidizing Agent
Air & Water Reactions
Highly flammable. Slightly soluble in water.
Fire Hazard
Excerpt from 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. For information on "Compatibility Group" letters, refer to Glossary section. (ERG, 2020)
Health Hazard
Excerpt from NIOSH Pocket Guide for Nitroglycerine:
Exposure Routes: Inhalation, skin absorption, ingestion, skin and/or eye contact
Symptoms: Throbbing headache; dizziness; nausea, vomiting, abdominal pain; hypotension; flush; palpitations; methemoglobinemia; delirium, central nervous system depression; angina; skin irritation
Target Organs: Cardiovascular system, blood, skin, central nervous system (NIOSH, 2023)
Reactivity Profile
Nitroglycerin is incompatible with heat, ozone, shock, and acids, and is an OSHA Class A Explosive (1910.109) (NIOSH, 2022).
NITROGLYCERIN, DESENSITIZED, [LIQUID] is less subject to explosion when heated or shocked than ordinary nitroglycerin because of the addition of desensitizing materials, but is still dangerous. May begin a vigorous reaction that culminates in a detonation if mixed with reducing agents, including hydrides, sulfides and nitrides. Reacts with inorganic bases to form explosive salts. Sensitized toward decomposition by the presence of metal oxides.
Belongs to the Following Reactive Group(s)

Response Recommendations
Isolation and Evacuation
Excerpt from 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, 2020)
Firefighting
Excerpt from 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, 2020)
Non-Fire Response
Excerpt from 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, 2020)
Protective Clothing
Excerpt from NIOSH Pocket Guide for Nitroglycerine:
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.
Remove: WHEN WET (FLAMMABLE) - Work clothing that becomes wet should be immediately removed due to its flammability hazard (i.e., for liquids with a flash point <100°F).
Change: DAILY - Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises.
Provide: QUICK DRENCH - 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, 2023)

First Aid
Excerpt from NIOSH Pocket Guide for Nitroglycerine:
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 IMMEDIATELY - If this chemical contacts the skin, immediately wash the contaminated skin with soap and water. If this chemical penetrates the clothing, immediately remove the clothing, wash the skin with soap and water, and 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, 2023)
