What is the main concern with Class 1 flammable liquids in a workplace environment?

Class 1 flammable liquids are those that have a flash point below 73°F (23°C), which makes them particularly hazardous in a workplace setting. The main concern with these liquids is their ability to easily combust when exposed to an ignition source, leading to potential fires or explosions. Their low flash point indicates that they can generate enough vapor at relatively low temperatures, which can mix with air to create a flammable atmosphere.

Understanding the characteristics of these liquids is crucial for implementing appropriate safety measures, such as proper storage, handling procedures, and adequate ventilation. This concern highlights the importance of classifying and managing flammable liquids effectively to minimize the risk of accidents and ensure a safe working environment.
