What can cause ignition in an LPG or CNG environment?

In an LPG or CNG environment, the presence of sparks from electrical equipment, open flames, or heat sources is a critical ignition source. Liquefied Petroleum Gas (LPG) and Compressed Natural Gas (CNG) are both highly flammable substances, and when they are mixed with air in the right proportions, they can easily ignite when exposed to sufficient heat or a spark.

Electrical equipment, if poorly maintained or malfunctioning, can produce sparks that may ignite gas leaks. Similarly, open flames from various sources, including equipment that is not properly shielded or maintained, pose a significant risk. Heat sources can also include anything from exhaust systems to hot surfaces that can trigger ignition under the right conditions. Therefore, ensuring that all electrical devices are rated for use in flammable environments and maintaining a safe distance from open flames and heat sources is essential for safety in areas where LPG or CNG is present.

Humidity and rain, although they can have other safety implications, do not directly cause ignition. Cold temperatures typically do not create ignition; instead, they may impact the performance of gas systems. Excessive noise, while a potential hazard in some circumstances, does not directly correlate with creating ignition sources in an LPG or CNG context.
