Which type of hazard does thermal radiation pose in an LPG incident?

Thermal radiation refers to the transfer of heat energy through electromagnetic waves, which can occur during incidents involving liquefied petroleum gas (LPG). In the context of an LPG incident, thermal radiation poses a significant risk of exposure to high temperatures that can lead to burns for individuals in the vicinity of a fire or explosion.

When LPG ignites, it can create intense heat that radiates outward, potentially causing severe injury to anyone who comes into contact with the radiated heat—this is primarily through the skin and eyes. Even without direct contact with flames, individuals exposed to this thermal radiation can suffer from heat-related injuries. Understanding the nature of thermal radiation helps responders to assess the dangers present and prioritize safety measures to mitigate risks associated with high-temperature exposure.

The other types of hazards listed do not specifically encompass the unique dangers associated with thermal radiation in an LPG incident, reinforcing the appropriateness of the correct answer.
