What risk is associated with placing gas cylinders in confined spaces?

Placing gas cylinders in confined spaces poses significant risks primarily due to the inability to ventilate hazardous fumes effectively. In enclosed environments, any leaks or accidental discharges from the cylinders can lead to a dangerous accumulation of gas. This situation can create a highly flammable atmosphere or introduce toxic gases without adequate ventilation, increasing the risk of health hazards or explosive conditions.

Proper ventilation is crucial in preventing the buildup of harmful concentrations of gases that could jeopardize safety. Ensuring that gas cylinders are used in well-ventilated areas limits the potential for dangerous situations arising from gases that are leaked or released unintentionally.
