Which feature is required for the doors of flammable/combustible liquid cabinets?

The requirement for doors of flammable or combustible liquid cabinets to be self-closing is essential for safety. Self-closing doors help ensure that the cabinet remains sealed and minimizes the risk of ignition or fire. When these cabinets are not in use, the self-closing mechanism automatically closes the doors, which helps to contain any flammable vapors that might escape. This feature is crucial in maintaining a controlled environment, and it significantly reduces the risk of fire hazards in laboratories or areas where flammable substances are stored.

Additionally, self-closing doors contribute to compliance with safety regulations and standards that aim to protect both personnel and property from fire risks associated with flammable liquids. In contrast, features like sliding doors, automatic locking, or open shelving do not provide the same level of hazard mitigation and control that self-closing doors do.
