Safety Regulations for Compressed Natural Gas and Liquefied Petroleum Gas Powered Vehicles: General: Notes

WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.

The following danger notes and safety regulations exclusively apply to maintenance and repair work on GM vehicles.
Natural gas/liquid gas is a hazardous substance and must be treated, stored and identified accordingly.
- Natural gas (CNG) is lighter than air and flows upwards when released.
- Liquid gas (LPG) is heavier than air and can collect in ground depressions.
- In combination with air, both gases form an explosive, flammable mixture.
- Concentrated natural gas can cause suffocation.
- In most countries, an odor-producing agent is added to the gas in order to give the gas a more intensive smell. This typical gas smell can be detected when the gas concentration is still well below the lower explosion limit (LEL). The odor-producing agent in the gas does not pose a health hazard for the consumer.
