What common materials are considered hazardous when using a torch?

The correct choice is focused on identifying the materials that pose significant fire hazards during torch operations. Wood, paper, and flammable liquids are substances that can easily catch fire when exposed to an open flame or high heat, making them particularly hazardous during torch activities.

Wood and paper are common combustibles found in many environments, and they burn readily, contributing to the rapid spread of flames if ignited. Flammable liquids, such as solvents, gasoline, or oils, can lead to explosive fire situations and are especially dangerous due to their ability to ignite at a relatively low temperature and produce large flames.

Understanding these materials is crucial for maintaining safety during torch operations, as they directly affect the risk of fire and the safety protocols that need to be implemented. Safety training emphasizes the importance of identifying and minimizing exposure to these hazards to prevent fire incidents.
