What is an explosion-proof refrigerator?
Explosion-proof refrigerators are designed to prevent ignition of flammable vapors or gases that may be present outside the refrigerator. This type of refrigerator must be used in locations such as solvent dispensing rooms, where a flammable atmosphere may develop at some time in the room.
What is the difference between a flammable liquid storage and explosion-proof refrigerator?
Explosion-Proof Units Here is the difference between the two types: Flammable storage refrigerators and freezers have no exposed ignition sources inside the cabinet, such as lights or switches, which could ignite vapors. Explosion-proof or spark-proof units have no interior or exterior ignition sources.
What makes a freezer explosion proof?
Explosion-Proof Refrigerators and Freezers The main difference is, in addition to the spark-free interior, they have a spark-free exterior, which prevents ignition from flammable vapors or gases that may be present outside the refrigerator or freezer.
What is an explosion proof freezer?
Explosion Proof Refrigerators & Freezers Units are designed with no internal electrical components and all external components are sealed per NFPA and OSHA guidelines.
What chemicals are used in freezers?
Certain appliances, such as refrigerators, air conditioners, and freezers, contain chemicals called fluorinated hydrocarbons. People often refer to these chemicals as Freon, which is a leading brand name. Freon is a dangerous substance.
Is a refrigerator flammable?
While most modern fridges are now covered in metal, older models, and even a handful of newer ones, still use a plastic backing. The plastic is highly flammable and, if ignited, can cause fires that develop quickly and powerfully while giving off toxic gases.
Can flammable materials be stored in refrigerator?
Requirement. Flammable liquids that must be chilled or frozen require special flammable storage refrigerators or freezers to minimize the risk of fire or explosion. Never store flammable liquids of any volume in a standard or domestic refrigerator or freezer. They have numerous ignition sources that could ignite vapors …
How chemicals should be stored and why is it important to store chemicals?
Chemicals must be stored at an appropriate temperature and humidity level. This can be especially problematic in hot, humid climates. As a rule, chemicals should not be stored near heat sources, such as steam pipes or laboratory ovens. Chemical should never be stored in direct sunlight.
What chemical do refrigerators use?
Freon

What is refrigerator refrigerant?
Substance used in a cooling mechanism of refrigerator, as the heat carrier which changes from gas to liquid and then back to gas in the refrigeration cycle. Most common commercial refrigerants are the chlorofluorocarbons (CFCs) which, because of their high ozone damaging potential, are being phased out.
Is combustible the same as explosive?
A combustible material is something that can burn (i.e., combust) in air. A combustible material is flammable if it ignites easily at ambient temperatures. Finely divided wood dust can undergo explosive combustion and produce a blast wave.
What is an explosion proof refrigerator?
Explosion-proof refrigerators Spark-free interiors and exteriors reduce the risk of explosion. These lab refrigerators are designed to be used in Class 1, Groups C and D, and Class 1, Zone 1, Group IIB areas where ignitable materials are normally present.
Can a refrigerator explode?
Engineered with no internal electrical components which could trigger an explosion. Refrigerators utilize ATEX and non-sparking components for the safe storage of flammable substances. All units feature a series of temperature alarms to keep stored products at peak effectiveness.
What type of refrigerators are used in laboratory?
These lab refrigerators are designed to be used in Class 1, Groups C and D, and Class 1, Zone 1, Group IIB areas where ignitable materials are normally present. Thermo Scientific explosion-proof laboratory refrigerators are particularly suited for safe storage in hazardous environments.
Are there any flammable material refrigerators that meet OSHA standards?
All flammable material refrigerators and explosion-proof refrigerators meet NFPA and OSHA standards. Availability of some units may be limited in certain geographic regions. flammable materials that require refrigeration?
