Hazards and Protection.
Storage
Store below 40C (104F), preferably between 15 and 30C (59 and 86F), unless otherwise specified by manufacturer. Store in a tight container. Store in a cool place in a airtight container. Protect from light.
Handling
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protection
Wear appropriate protective gloves, clothing and goggles.
Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks
Keep sparks, flames, and other sources of ignition away. Keep material wet. Wet spilled material before picking it up. Do not attempt to sweep up dry material.
Stability
No data.
Incompatibilities
If mixed with reducing agents, including hydrides, sulfides and nitrides.

Fire.
Flash Point,°C
198
Fire fighting
Dangerously explosive. Do not fight fires in a cargo of explosives. Evacuate area and let burn.
Fire potential
This material is probably combustible.
Hazards
May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. May react vigorously or explosively on contact with water. May decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Health.
Exposure effects
Abnormally low blood pressure is common. Low heart rate may occur in predisposed patients; reflex rapid heart rate may occur. Death occurs secondary to circulatory collapse or respiratory failure. With therapeutic use - 1. Headache and dizziness are common, even after administration of therapeutic doses. Acute wernicke's encephalopathy from intravenous infusions may be precipitated by ethanol and propylene glycol diluents. In male rats, a dominant lethal test showed no effect on male fertility; interstitial cell tumors of rat testes were induced after nitroglycerin exposure. Results on teratogenicity in rats are conflicting.
   Ingestion
Nausea, vomiting, colicky pain, and diarrhea may occur.
   Inhalation
Inhalation of decomposition products may cause severe injury or death.
   Skin
Contact with substance may cause severe burns.
   Eyes
LOSS OF VISION - A transient loss of vision reportedly occurred before acute toxic effects from nitroglycerin exposure. Constriction of the pupil and corneal damage occurred after intravenous exposure.

First aid
 
   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.
   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.
   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.
   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.
