Handling and use of compressed gas containers and systems shall be provided with approved what by natural or artificial means?

The handling and use of compressed gas containers and systems necessitate effective ventilation to ensure safety. Ventilation is crucial as it helps to dissipate any potential leaks of the compressed gas that may pose a risk of fire or explosion. Adequate ventilation minimizes the accumulation of gas in any area, thus reducing the chances of hazardous situations arising from the presence of flammable gases or other harmful substances.

Natural ventilation can occur through open windows and doors, while artificial ventilation systems can include fans or exhaust systems designed to maintain a safe environment. By ensuring proper airflow, the concentration of any potential gas leak is kept within safe limits, protecting both the personnel handling the gases and the surrounding environment.

In contrast, although insulation, heating, and lighting may be relevant to other contexts within safety practices, they do not directly address the critical need for mitigating risks associated with gas leaks. Therefore, the emphasis on ventilation as a necessity for safety in the handling of compressed gases is paramount.
