Which hazard is confirmed under SARA 311/312 for pressure?

The correct response regarding the hazard confirmed under SARA 311/312 for pressure is affirmatively "Yes." This classification pertains to specific substances that can pose physical hazards due to their pressure characteristics.

SARA Title III, also known as the Emergency Planning and Community Right-to-Know Act (EPCRA), requires facilities to report on hazardous substances present in large quantities. Under Section 311 and 312, it delineates the criteria for notifying local authorities about the hazards of substances stored and used at a facility, including their physical and health hazards.

For substances classified as physical hazards, any materials that can produce dangerous conditions under pressure (such as gases or liquids in pressurized containers) must be reported. This includes hazards related to explosive reactions when exposed to pressure, which are crucial for safety in industrial refrigeration settings. Acknowledging pressure as a confirmed hazard is vital for ensuring proper safety measures and emergency preparedness are in place around such potentially dangerous materials.
