Product Hazards
| Product | Leak Type | Vapors | Health Hazard | Fire Hazard |
| Natural Gas | Colorless, odorless, tasteless gas; | Lighter than air | Extremely high concentration may cause irritation or asphyxiation | Extremely flammable |
| Natural Gas Liquid (NGL) | Gas | Heavier than air | Dangerous if inhaled | Extremely flammable |
| Nitrogen | Inert gas | Lighter than air | Dangerous if inhaled | Non-flammable but can displace oxygen |
| Gasoline and Diesel | Liquid | Heavier than air | Irritating to eyes and skin; vapors at high concentrations may affect central nervous system | Extremely flammable |
| Crude Oil | Liquid | Heavier than air | Possible presence of H2S, a toxic gas | Extremely flammable |
| Gasoline, Diesel, Jet Fuel, Heating Oil, Transmix | Liquid | Heavier than air | Irritating to eyes and skin. Vapors at high concentration may cause central nervous system effects | Extremely flammable |
| Propane, Butane | Liquid/Gas |
Heavier than air | Respiratory tract irritant. May cause central nervous system effects. |
Extremely flammable |
Identifying a Pipeline Leak
Use your sight, smell and hearing to help recognize a pipeline leak.
Do you see . . .
- Dead or discolored vegetation.
- Pooling of liquids on the ground.
- Bubbling in pools of water.
- Sheen on the surface on water.
- A white vapor cloud that resembles smoke.
- Dirt blowing from a hole in the ground.
- Fire coming out of or on top of the ground.
- An area of frozen ground when ambient temperatures are warmer than freezing.
- An unusual area of melted snow in winter.
Do you smell . . .
- An odor like petroleum liquids or gasoline.
- An odor like rotten eggs or a burnt match.
- A pungent odor.
* In its purest state, natural gas is colorless and odorless. Natural gas supplied to a home or business may contain mercaptan, which has an odor similar to rotten eggs to assist in detecting a gas leak. Unprocessed natural gas also may have a petroleum-like odor.
Do you hear . . .
- A hissing or whistling noise.
- A loud roaring sound like a jet engine.
