Easily ignited materials like gases, liquids and solids must be stored carefully. The flammable storage cabinets are essential to protect the workspace and workers. Also, the right flame proof material should be used to match the specific type of substance that is being stored. Here are a few of the most common types of flammable storage items:
Flammable liquids are known to automatically ignite in the event of reaching a certain temperature. It is practical to store these liquids in an environment that is kept below a temperature of 37.8° C (100° F). If the liquids are left to reach a higher temperature, there is a risk of the material giving off a vapor that can lead to burning. The different liquids include alcohols, paint thinners, paints and petrol.
The flammable gas is likely to burn when combined with air or a similar oxidant and when in contact with an ignition source. This type of substance can be extremely hazardous even when safely locked in a proper cabinet. Even a minimal amount of escaping gas can lead to an explosion or fire in favorable conditions. Common forms of flammable gases include methane, hydrogen sulfide, carbon monoxide, acetylene and propane.
Chemicals have the potential to explore as a result of shock, friction or heat. There are even touch sensitive chemicals that will activate even when its storage container is touched or brushed against. Also, there is more risk with the older chemical stock which can start to degrade over time. Specifically manufactured or naturally occurring chemicals include nitoso, haloamine, oxonides, azides and acetylides.
Certain chemicals are known to unexpectedly evolve oxygen with slight heating or even at room temperature. This build up of oxygen can lead to a fire and cause damage to the local surroundings. To minimize the risk of an accident with oxidizing chemicals, a secure and purpose-built cabinet must be used. Also, there is the risk of chemicals mixing if stored together, so a separate space is required for each type of chemical. Common types of oxidizing chemicals include bleach, concentrated Nitric acid, and hydrogen peroxide.
There are plenty of solids that are highly dangerous. Picrate salt is a flammable solid and common in laboratories, dye manufacturing and used to create explosives. It only needs a small amount of friction, shock or heat to react. Also, cellulose nitrate easily catches fire and a popular choice for photographic negatives and old film.
