Thermal expansion and contraction is a general physical phenomenon of an object, and an increase in temperature causes an increase in the volume pressure of a hazardous chemical. The flammable liquid has a relatively large expansion coefficient and is stored in a closed container. The volume is easily expanded after being heated, and the vapor pressure is increased to increase the internal pressure of the container. If the pressure exceeds the pressure of the container, the container may be damaged. Even bursting.
The phenomenon of "drums" in the iron drums containing flammable liquids during the hot season and the bursting of the glass containers are all due to thermal expansion. If the container is open, the liquid will expand beyond its capacity and overflow, causing run, run, drip, and leak.
The best way to deal with it is
Classification of hazardous chemicals!
Chemical dangerous goods are generally classified into explosive articles, water-burning articles, pyrophoric articles, flammable solids, flammable and combustion-supporting gases, corrosive articles, oxidants, and the like. It is forbidden to classify, store, separate, and store these items. It is strictly forbidden to mix items that are incompatible with each other, have different fire extinguishing methods, and are prone to spontaneous combustion.
Types of Chemical Safety Storage Cabinets
In storing chemicals, colors and labels are generally used for identify different chemicals, so if fires occur, it is easy for firemen to indentify hazardous chemicals.
|Yellow Safety Cabinet for storing flammable liquids(low and median flash point liquid1, flash point＜37.8℃)||Red Safety Cabinet for storing paintings, oil and other flammable liquids(high flash pointliquid2, flash point≥37.8℃)||Blue Safety Cabinet for storing corrosive liquids3|
Polyethylene Corrosive Cabinets
|White Safety Cabinet for storing toxic chemicals||Green Safety Cabinet for storing insecticides,pesticides, disinfectors and other chemicals||Polyethylene Corrosive Cabinet for storing strong polyethylene|
How to choose chemical storage cabinets?
|- Choose chemical storage cabinets according to the types and volumes|
|Confirm the containers are as below: safety cans, oily drums of less than 55Gal, small volume of coating containers, 4L bottles, aerosol containers or smaller bottles. All storage containers must be airtight.|
|- Confirm the volume of needed chemical storage cabinets|
|Choose cabinets according to your needed volume.Bigger cabinets offer more storage space. SYSBEL Safety Cabinets have 11 different volumes, namely 4Gal, 12Gal,22Gal, 30Gal, 45Gal, 54Gal, 55Gal, 60Gal, 90Gal, 110Gal and 120Gal, you can choose the best type based on storage space and volume.|
|- Ensure the service environment of chemical storage cabinets|
|Ensure cabinets are used on horizontal interface, and free from fire sources, dry and ventilated. Choose types based on needs, such as console cabinets, desktop cabinets or cabinets for ventilation hood in the lab, (SYSBEL 10Gal Safety Cabinet) . Also, you can base on leakage prevention demand to install proper PVC tray.|
- Conform the Chemical properties of the chemicals to be installed
Color management + 5Label management = 5Identifiability
Color management and label management helps you to identify, manage and distinguish between a variety of dangerous chemicals in the storage process.According to the Material Safety Data Sheets (MSDS) of chemicals planned to be stored, you can determine their chemical characteristics and storage requirements, choose corresponding categories of safety storage cabinets in color and label management system, classify and grade chemicals, to avoid the risk of fires, gas reaction and explosion due to incompatible chemical storage.
