Why must flammable liquids be stored in approved cabinets?

Flammable liquids must be stored in approved cabinets primarily to reduce the risk of fire and explosion. These cabinets are specifically designed to contain flammable substances safely and minimize hazards. They are built with materials and features intended to withstand fire and prevent ignition sources from reaching the stored liquids.

By storing flammable liquids in these cabinets, laboratories can control the risks associated with volatile substances, such as vapor accumulation and accidental ignition. Approved cabinets also help to contain spills, thereby limiting the potential for dangerous situations and ensuring compliance with safety regulations. Overall, this practice is essential for maintaining a safe laboratory environment where flammable materials are used and stored.
