Chemical Name: Pentaerythritol Tetranitrate containing not less than 25% water or not less than 15% desensitizer
Common Synonyms: PETN wet
Description: White crystalline solid, supplied wetted to reduce explosive risk
Main Use: Explosives, detonators, and industrial blasting applications
Odor: Odorless or faint alcohol scent
Risk Type: Explosive hazard, even when wetted
Primary Danger: Accidental detonation from impact, friction, or static
Acute Health Effects: Headache, nausea, dizziness if inhaled
Chronic Exposure Concerns: Prolonged skin contact can cause local irritation
Environmental Threat: Persistent contaminant if not controlled
Warning: Wetting reduces risk but doesn’t negate it
Pentaerythritol Tetranitrate: Main ingredient, varies in percentage according to water or desensitizer content
Water: Not less than 25% by mass as desensitizer
Alternative Desensitizer: Non-volatile liquids or waxes, minimum 15% by mass
Impurities: Standard processing residues at trace levels
Inhalation: Move person to fresh air, seek medical attention if unwell
Skin Contact: Immediately wash skin with soap and water, remove contaminated clothing
Eye Contact: Rinse with water cautiously for several minutes, seek medical evaluation if irritation develops
Ingestion: Seek medical attention promptly, do not induce vomiting
Symptoms to Watch: Dizziness, headache, rash, respiratory distress
Suitable Extinguishing Media: Flood with water only if trained, dry sand for local incidents
Hazards During Fire: Risk of violent detonation from heat or shock
Protective Equipment: Full-face respirator, heavy protective clothing
Firefighting Actions: Evacuate area, do not approach unless necessary
Special Note: Do not use foam or dry chemical that could create friction
Evacuation: Clear surrounding area immediately
Containment: Prevent dust or debris, avoid sweeping or using tools that can create sparks
Cleanup: Collect material with tools designated for explosives, keep wetted, place in safe container
Personal Protection: Wear gloves, goggles, and protective gear
Environmental Protection: Prevent release to waterways and drains
Storage Requirements: Store in cool, dry designated magazines built for explosive materials
Temperature Limits: Avoid temperature extremes; hot conditions hasten drying and risk
Handling Precautions: Handle gently, no rough handling, avoid dropping or impact
Segregation: Keep away from corrosives, flammables, oxidizers, acids, or heat sources
Training: Only trained personnel should handle
Engineering Controls: Local exhaust ventilation in handling and transfer areas
Personal Protective Equipment: Nitrile or Neoprene gloves, goggles, flame-retardant clothing
Exposure Limit: No established occupational exposure limits, but minimize any contact
Hygiene Practices: Wash hands thoroughly after handling, do not eat or drink near material
Static Control: Ground all equipment and containers before transfer
Appearance: White crystalline powder, wetted for safety
Odor: Odorless or mild alcohol scent
Solubility: Slightly soluble in water, highly soluble in acetone
Density: Varies by wetting
Melting Point: Decomposes before melting at high temperatures
Sensitivity: Extremely sensitive to impact, friction, and heat in dry form
Stability: Stable if kept wet with sufficient water or desensitizer
Instability: Drying increases explosive risk
Incompatibilities: Strong acids, alkalis, heavy metals, reducing agents
Decomposition: Rapid at elevated temperatures with release of toxic gases
Polymerization: No risk under normal storage
Short-Term Exposure: Can cause headaches, nausea, skin rashes
Long-Term Effects: Prolonged exposure increases sensitization and risk of dermatitis
Target Organs: Central nervous system, cardiovascular system
Routes of Entry: Inhalation, ingestion, skin absorption
Reported Cases: Industrial exposure linked to chronic headaches and dizziness in some workers
Fate in Environment: Persistent if spilled into soil or waterways
Bioaccumulation: Data lacking, but likely low for PETN itself while metabolites may persist
Aquatic Toxicity: Harm to aquatic life possible even at low concentrations
Cleanup Priority: Immediate isolation and removal from sensitive habitats
Wastewater Impact: Not suitable for dilution in wastewater treatment
Waste Disposal: Treat as hazardous waste, consult local explosive disposal experts
Dissolution: Not recommended to drain or landfill
Container Disposal: Triple rinse or return to supplier for safe destruction
Legal Obligation: Comply with explosives and hazardous waste laws
Transportation Class: Classified as Class 1.1 Explosive
Packaging: Only in approved, labeled, watertight containers
Shipping Restrictions: Regulated by international and national law, strict route and manifest requirements
Incident Response: Emergency information available to all handlers and carriers along the route
Status: Strictly regulated as an explosive under international rules
Reporting: All movements tracked; unauthorized possession penalized
Workplace Controls: Trained, authorized personnel, periodic compliance audits
Community Safety: Risk assessments required for any storage or usage facility
Environmental Regulation: Subject to hazardous substance and pollution controls
