What precautions should be taken when working with flammable materials?

When working with flammable materials, the correct approach is to store them away from heat sources and ensure proper ventilation. This is critical because flammable materials can easily ignite when exposed to heat or sparks, leading to dangerous fires or explosions. Proper ventilation helps dissipate any vapors that may accumulate, reducing the risk of ignition and enhancing safety for personnel handling these substances.

In contrast, keeping flammable materials in direct sunlight is not advisable as the heat from the sun can raise the temperature of the materials, potentially increasing the risk of combustion. Utilizing sealed containers can be beneficial; however, it is not sufficient to overlook the surrounding conditions that can contribute to safety hazards. Additionally, storing flammable materials alongside combustible materials poses a significant risk since if one material ignites, it can easily lead to the ignition of the other, compounding the potential danger. Therefore, the measures of proper storage away from heat sources and ensuring good ventilation are fundamental to managing risks associated with flammable materials.
