Chemical & Response Details
| Also known as | Coal tar naphthaSolvent naphtha (coal tar)Creosote oil lightCoal tar light oilTar distillate |
| Appearance | Dark brown to black oily liquid with a characteristic naphthalene or aromatic odor. Mixture of aromatic hydrocarbons derived from coal tar distillation. |
| Flash Point | Varies by fraction, typically 0-38C (32-100F) for light distillates |
| Boiling Point | Wide range 150-300C (302-572F) depending on distillation fraction |
| Vapor Density | Heavier than air (vapor density >3) |
| Water Reactivity | No significant reaction with water; floats and may spread on water surface |
| Extinguishing | Alcohol-resistant AFFF foam, dry chemical, CO2; water spray for cooling only |
| PPE | ⚠️ Level B minimum; SCBA required in vapor areas; chemical-resistant gloves and suit; eye protection mandatory due to skin/eye irritant properties |
| Isolation | ERG 128: Initial isolation 50m all directions; protective action distance 150m downwind for small spills, 300m for large spills; evacuate area if tank/container exposed to fire |
Chemical details are general reference only. Always verify with current SDS, ERG, and SOP/SOG.
Common hazards (high level)
- HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
- Vapors may form explosive mixtures with air.
- Vapors may travel to source of ignition and flash back.
- Most vapors are heavier than air. They will spread along the ground and collect in low or confined areas
- Vapor explosion hazard indoors, outdoors or in sewers.
- Those substances designated with a (P) may polymerize explosively when heated or involved in a fire.
- Runoff to sewer may create fire or explosion hazard.
- Containers may explode when heated.
First actions (field-minded)
- CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper
- Keep unauthorized personnel away.
- Stay upwind, uphill and/or upstream.
- Ventilate closed spaces before entering, but only if properly trained and equipped.
- Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
- Consider initial downwind evacuation for at least 300 meters (1000 feet).
