What best describes the conditions for Class 3, Division 2 materials?

Class 3, Division 2 materials encompass flammable liquids that have a flash point of 140°F (60°C) or higher and may still pose significant risk under certain conditions. These materials are usually stored under conditions that minimize the potential for ignition. Therefore, the description that they are stored without risk of ignition is accurate because it emphasizes the safety measures taken to handle these potentially hazardous substances.

While it is true that Class 3, Division 2 materials may be manufactured and handled (which might pertain to the first option), the key aspect is that storage practices are designed to mitigate risks associated with their flammability. Proper storage conditions include the use of appropriate containers, ventilation, and maintaining a safe distance from ignition sources.

The incorrect options suggest scenarios that do not align with established safety protocols for Class 3, Division 2 materials. For example, saying they are not stored at all overlooks the critical point that safe and effective storage is vital to prevent accidents, and the notion that they are in use constantly fails to acknowledge the importance of managing and reducing risk, which includes proper storage practices.
