Storing Combustible and Flammable Liquids in a Laboratory Refrigerator
The storage protocol for flammable and combustible liquids has to be followed exactly. There are two crucial aspects when it comes to such storage conditions. First is the basic make as well as the kind of the laboratory refrigerators used. Next is to keep all inflammable or combustible materials away from anything that could set it off. Regular domestic refrigerators have several elements inside them that could trigger off an explosion or fire.
When it comes to proper laboratory refrigeration for volatile liquids, you'll have to choose between explosion-proof and inflammable models. There are also modified domestic models that are available. But make sure that the modification is done by a competent person who possess the needed skills in dealing with hazardous electrical components. Refrigerators that are modified in this way are called “modified domestic refrigerators.”
After you have chosen the right type of refrigerator, next is to label them accurately. These labels should specify
- The fridge cannot be used to store anything other than flammable or volatile substances.
- If controllable, flammable substances are stored in a non-explosion proof laboratory refrigerator, this fact should be cited.
- Also it needs to be stated that food items of any kind cannot be stored in these refrigerators.
In terms of construction, if you are looking to store combustible or flammable liquids, then explosion-proof refrigerators will serve the purpose. These fridges work such that they do not allow external nor internal factors to work on the chemicals stored. Moreover they have supplemental precautionary features such as automatic door closing, friction latches, door gaskets that are magnetic and specially constructed interior casing. All of these will ensure your laboratory is safe from unforeseen accidents .
A designated scheme has to be followed when it comes to the placement of the refrigerator in the lab. This includes a specific clearance on all sides, and sufficient ventilation. It should also never be placed too close to the exits or entrances of the laboratory. On the actual storage of the chemicals, put in only specific amounts that you will need soon. Liquids stored have to be in the right containers, made of the specified materials. Flammable liquids sometimes shouldn’t be covered with certain materials like plastic or glass.
Laboratory refrigerators need to undergo periodic maintenance checks. This includes thorough cleaning of the interiors as well. Chemicals need to be stored in containers that are specifically designated to hold them. Maintenance of these laboratory refrigerators has to be the sole duty of a single lab-in-charge. A set protocol should be in place and known to all related to the lab in the event of an accident or an emergency evacuation of the laboratory. A well-defined technique is crucial for the safe storage of combustible and flammable liquids.
