What is essential to ensure during the storage of gas containers?

Keeping gas containers away from heat sources is vital for maintaining safety and preventing hazardous situations. Gas containers can be sensitive to temperature, and exposure to heat can increase the pressure inside the container, potentially leading to leaks, ruptures, or even explosions. Proper storage practices include ensuring that gas containers are stored in cool, well-ventilated areas, away from any equipment or materials that may generate heat.

The other choices do not align with safe storage practices. Storing gas containers in the same room could lead to dangerous accumulations of gas if a leak occurs. Charging all containers does not apply to gas storage, as containers should be kept full only to specifications and needs. Incorrectly labeling containers can lead to confusion and hazardous misuse, undermining safety protocols. Therefore, the emphasis on keeping gas containers away from heat sources is crucial in preventing incidents and ensuring a safe environment.
