What does good ventilation help prevent when using LP-Gas in enclosed areas?

Good ventilation is essential when using LP-Gas in enclosed areas because it helps prevent the accumulation of gas. LP-Gas, being heavier than air, can settle in low areas and create a hazardous environment if not adequately ventilated. Adequate airflow allows for the dispersion of any gas that may leak, minimizing the risk of harmful concentrations building up and leading to potential combustion or asphyxiation hazards.

In contrast to the other choices, excessive pressure build-up is more related to tank safety features and the design of gas systems rather than ventilation. Accidental gas leaks are more about the integrity of the equipment and connections used in gas handling. Overheating of equipment is primarily a concern concerning the equipment's operation and design rather than the ventilation situation. Overall, good ventilation plays a crucial role in safety by ensuring that any gas present is quickly dispersed, mitigating the risk of dangerous conditions arising from gas accumulation.
