If you are storing, transporting or using flammable materials in an environment with ambient temperatures above their flashpoints, you must use extreme caution to prevent combustion or ignition. Flammable liquids release a vapor that can ignite at standard working temperatures, especially in a poorly ventilated area. Similarly, a combustible material can release a flammable vapor when its temperature rises above its flashpoint. These vapors are invisible and dangerous.
Since the vapor released from a flammable liquid is gas, it can easily absorb into other materials. These materials that absorb the vapors can then release this vapor back into the air, even after you clean up the primary source of flammability. Flammable and combustible vapors are often denser than air and can spread quickly. If these vapors ignite, the flame can travel back to the liquid source by following the vapor fumes. This occurrence is known as a flashback.
To reduce significant fire hazards, here are some storage tips for flammable and combustible materials.
Correct ventilation: Vapors are denser than air, causing them to ignite easily in areas with poor ventilation.
Separate materials from ignition sources: Store flammable and combustible materials away from open flames or sparks to prevent fire hazards.
Keep incompatible materials away from one another: When incompatible flammable and combustible materials mix, it can cause dangerous chemical reactions such as oxidation and spontaneous combustion. Consult a dangerous goods segregation table to determine the correct distance for spacing these materials.
Contain spills: Proper cleanup is vital when working with flammable and combustible materials to prevent cross-contamination.
Reduce human error: Frequently check on your storage units and the hazardous materials inside to ensure they do not have any signs of damage and are without leaks or punctures. Use all storage units properly for maximum safety.
