Hazards and Protection.
Storage
Store at only in permanent magazine. This high explosive should be kept well away from initiator explosives, protected from physical damage, separated from oxidizing materials, combustibles and sources of heat.
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
Workers should be supplied with protective clothing that is laundered at regular intervals. Wear appropriate eye protection and protective clothing to prevent skin and eye contact.
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
Reactive at high temperature or pressure. Moderate hazard. Will detonate under strong shock.
Incompatibilities
Sensitive to heat and shock Reacts with reducing agents.

Health.
Exposure limit(s)
TLV: ppm; 0.5 mg/m3 (skin) (ACGIH 1991-1992). OSHA PEL: TWA 1.5 mg/m3 skin NIOSH REL: TWA 0.5 mg/m3 skin NIOSH IDLH: 500 mg/m3
Exposure effects
CNS effects include headache, dizziness, altered mental status, confusion (lethargy progressing coma), seizures, syncope; occur secondary to CNS hypoxia, usually with levels > 20%.
   Ingestion
Nausea and vomiting may occur.
   Inhalation
Dyspnea and tachypnea may occur.
   Skin
Central cyanosis unresponsive to oxygen therapy is classic.
   Eyes
May cause burns. See inhalation.

First aid
 
   Ingestion
DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician.
   Inhalation
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used.
   Skin
IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.
   Eyes
First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
