In designing electrical installations, it is crucial to consider both combustible materials in proximity and the presence of flammable liquids. Each of these factors contributes significantly to the overall fire hazard assessment.

Combustible materials nearby can ignite due to heat generated by electrical equipment, short circuits, or arcing. Proper clearance, shielding, and the use of non-combustible materials help mitigate these risks. Additionally, understanding the types of materials present and their ignition temperatures is essential for a safe design.

In parallel, the presence of flammable liquids poses an even greater risk. Liquids such as gasoline, solvents, or oils can easily ignite when exposed to sparks or heat. Therefore, particular attention must be paid to the placement and protection of electrical installations in areas where these liquids are stored or used. Adequate ventilation and explosion-proof equipment may also be necessary in such environments.

By addressing both combustible materials and flammable liquids, a comprehensive approach to fire safety in electrical design is ensured, aligning with safety regulations and best practices. This dual consideration is fundamental for minimizing the risk of fire hazards and ensuring safe electrical installation practices.
