What is a common safety consideration when using LPG and CNG?

A common safety consideration when using LPG (Liquefied Petroleum Gas) and CNG (Compressed Natural Gas) is ensuring adequate ventilation. Both LPG and CNG are gases that can pose significant safety risks if they accumulate in confined spaces. Adequate ventilation is crucial for preventing the buildup of these gases that could lead to asphyxiation or increased risk of fire and explosion. Proper ventilation allows harmful gases to dissipate, maintaining a safe environment and reducing the chances of dangerous concentrations forming.

In contrast, other considerations, while they may be necessary in specific contexts, do not address fundamental safety issues in the same way. For instance, only using approved fuel types is essential for compliance and operational effectiveness but does not directly mitigate the risk posed by gas accumulation. Inefficient engine operation pertains to performance rather than safety, and ignoring possible leaks would be reckless as it greatly heightens the risk of hazardous situations arising from gas escape. Thus, adequate ventilation stands out as a primary safety focus when utilizing LPG and CNG.
