Ben Hirst Hazardous Materials Awareness and Operations Practice Exam

State of matter is conveyed by hazard pictograms, and a gas is represented by a gas cylinder, which signals compressed or liquefied gas stored under pressure. This symbol specifically indicates a gaseous form, distinct from other hazards. The skull-and-crossbones icon points to toxicity, the flame icon to flammability, and the water-droplet icon is associated with liquid-related hazards, not gas. Therefore, the label with the gas cylinder best indicates that the product is a gas.
