Which of the following is a common safety practice when using LP gas?

Keeping a fire extinguisher nearby is a crucial safety practice when using LP gas due to the highly flammable nature of gas. In the event of a fire or leak, having a fire extinguisher readily accessible can help manage an emergency quickly, potentially preventing injuries and property damage. It is essential for users to be prepared and equipped to respond to any incidents involving LP gas, as quick action can mitigate dangerous situations.

The other practices listed do not align with established safety protocols. For instance, storing tanks in a hot environment poses a significant risk, as high temperatures can increase pressure within the tank, leading to leaks or explosions. Using LP gas in unventilated areas is also hazardous since it can cause the accumulation of gas, increasing the risk of inhalation and fire. Additionally, turning off all gas appliances during refueling is an important safety step, but it doesn't directly address immediate safety measures that are necessary to prevent or respond to fire hazards. Keeping a fire extinguisher nearby remains a proactive stance against potential emergencies.
