Overview
This section outlines the specific hazards that may arise during a fire involving the substance or mixture. Understanding these hazards is crucial for safe and effective firefighting operations.
5.2 Special Hazards Arising from the Substance or Mixture
Hazardous Combustion Products
Common Products
- Carbon monoxide (CO)
- Carbon dioxide (CO₂)
- Other toxic gases and vapors
- Generation of dense, black smoke
- Metal oxides
- Possibility of incomplete combustion products
Specific Hazards
Critical Risks
- Risk of containers bursting when heated
- Formation of explosive gas/air mixtures
- Risk of violent reaction
- Potential for dust explosion (if applicable)
Physical Hazards During Fire
Container and Vapor Risks
- Risk of container explosion due to pressure build-up
- Potential for violent rupture of containers
- Formation of flammable vapor clouds
- Risk of flashback if vapors travel to ignition source
Chemical Decomposition Products
Potential Decomposition Products
- Nitrogen oxides (NOx)
- Sulfur oxides (SOx)
- Halogenated compounds
- Metal oxides
Environmental Hazards
Environmental Impacts
- Contaminated firefighting water must be contained
- Risk of environmental damage from fire runoff
- Potential for ground and water contamination
- Formation of toxic smoke plumes
Additional Information
Special Considerations
- May intensify fire; oxidizer (if applicable)
- Flammable/explosive vapors may accumulate in confined spaces
- Contaminated firefighting water must be disposed of properly
