What type of hazard is signified by the gas cylinder pictogram?

The gas cylinder pictogram is specifically used to represent "Gases Under Pressure." This designation highlights the hazards associated with gases that are stored in pressurized containers, which can pose significant risks if the cylinder is damaged, leaks, or ruptures.

Understanding this pictogram is crucial for ensuring workplace safety because gases under pressure can lead to explosive releases, severe injuries from rapidly expanding gases, or other dangerous situations if not handled correctly. This recognition aligns with the important aspects of the Hazard Communication Standard, which emphasizes the need to communicate the potential hazards of chemical substances to employees effectively.

The other options, while they may encompass potential hazard categories, do not specifically align with the specific meaning of the gas cylinder pictogram. Therefore, recognizing that the primary designation of this pictogram is "Gases Under Pressure" emphasizes the need for appropriate handling and storage practices to mitigate risks associated with such gases.
