# Gassy Accidents (DD-371)

> Trucks carry natural gas either compressed (CNG) in high-pressure cylinders or liquefied (LNG) in insulated tanks at about minus 162 degrees Celsius. Tanks are built to withstand pressure and impacts, but collisions, equipment failures and leaks can release flammable gas that may ignite into fires or explosions. Regulations, maintenance and driver training reduce the risk. The footage shows a gas tanker fire and explosion.

## Quick facts

- **DD-371-F01**: Compressed under high pressure. _(Write-up · Exhibit A (CNG))_
- **DD-371-F02**: Liquefied at about -162 C. _(Write-up · Exhibit B (LNG))_

## Write-up

Gas tankers carry fuel under pressure or deep cold. A ruptured tank can release gas that ignites.

1. **CNG**: Compressed under high pressure.
2. **LNG**: Liquefied at about -162 C.
3. **Tanks**: Tanks resist pressure.
4. **Hazard**: Leaks can ignite.
5. **Safety**: Rules and training reduce risk.

### Transcript

Did you know gas trucks which transport liquefied natural gas or compressed natural gas face explosion risks due to the highly flammable nature of the gases they carry. These trucks are built with specialized tanks designed to withstand high pressure and extreme temperatures but accidents can still occur from collisions, equipment failures or leaks. A ruptured leak can lead to the rapid release of gas which, if ignited, can cause explosions or fire. Strict safety regulations, rigorous maintenance, and trained personnel are crucial in mitigating these risks ensuring safe transportation of gas products while minimizing the potential for catastrophic incidents. NOW YOU KNOW!
