Chemical resistant storage is critical for laboratories, industrial facilities, janitorial services, agriculture, and any application requiring dangerous liquid handling. The right containers promote safety and regulatory compliance while organizing chemicals for maximum access and efficiency.
Types of Chemical Resistant Containers
There are three main types of chemical resistant storage containers - plastic, stainless steel, and fiberglass. Each has its own advantages and disadvantages.
Plastic
Plastic containers are lightweight, corrosion resistant, and relatively inexpensive. Common plastic materials used are polyethylene, polypropylene, Teflon, and PVDF. Polyethylene and polypropylene are suitable for storing acids, bases, and solvents. Teflon has excellent chemical resistance but is more expensive. PVDF is resistant to a very wide range of chemicals.
The main downside of plastic is durability - it can become brittle after prolonged chemical exposure. Plastic is also prone to static buildup which can cause sparks or explosions.
Stainless Steel
Stainless steel offers excellent durability and chemical resistance. It is suitable for highly corrosive chemicals like nitric acid. Stainless steel is non-reactive, spark resistant, and withstands high temperatures.
The drawbacks are that stainless steel is heavy and one of the more expensive options. It is also prone to corrosion from certain chemicals like hydrochloric and sulfuric acids at high concentrations.
Fiberglass
Fiberglass reinforced plastic (FRP) containers combine the corrosion resistance of plastic with the durability of fiberglass. FRP has good impact resistance and is lighter than stainless steel.
The downsides are that fiberglass can be degraded by some chemicals, is prone to cracking, and is electrically conductive. It is also more expensive than plastic. Proper grounding is required to prevent static buildup.
Chemical Compatibility
When selecting chemical resistant storage containers, it is crucial to consider chemical compatibility. The container material must be resistant to the specific chemicals it will hold to avoid dangerous reactions or corrosion over time. Some key factors in determining chemical compatibility include:
- The chemical concentration - More diluted solutions are generally less reactive than concentrated chemicals. Always check compatibility at the highest concentration that will be stored.
- Exposure time - Some materials that are compatible for short-term contact can degrade over continual exposure. Check compatibility for the maximum expected storage duration.
- Temperature - Heat can accelerate chemical reactions and breakdown materials faster. Verify compatibility at the highest temperatures the containers may encounter.
- Mechanical stress - Agitation, mixing, and frequent opening/closing also degrade materials over time. Account for expected mechanical wear.
The best resource for verifying chemical compatibility is chemical resistance charts from reputable container manufacturers. These charts rate the compatibility of various chemicals with each type of container material, often using an A-F letter grade system. Always consult the charts for the specific brands and formulations of chemicals to be stored.
It's also advisable to discuss unique chemical combinations with the container supplier to identify any potential incompatibilities not covered in the charts. Keep in mind that some chemicals may require specialized coatings or treatments for adequate resistance. Proper compatibility research during selection will prevent dangerous container failures down the road.
Safety Features
When selecting chemical resistant storage containers, safety should be a top priority. Proper storage helps mitigate risks and prevent accidents or exposure. Here are some key safety features to look for:
Lids
- Tight-fitting lids are crucial to prevent spills or leakage. Look for lid designs with latches, seals, or gaskets for optimal containment.
- Some containers have vented lids to allow gases to escape while keeping liquids and vapors contained. Vents can help stabilize internal pressure.
- Make sure lids fully seal containers during transport or movement. Leak-proof lids maintain safety if containers tip over.
Ventilation
- Proper ventilation around storage containers is important. Some chemicals emit hazardous fumes that require airflow to dilute vapors.
- Containers themselves may have built-in vents. Also allow sufficient room between containers for air circulation.
- Follow regulations or safety data sheets for required ventilation needs per chemical. Have a working ventilation system if storing large quantities.
Secondary Containment
- Secondary containment provides an extra layer of spill protection. It catches leaks in case primary storage containers fail.
- Common forms are containment pallets, berms/dikes around shelves, or dedicated containment areas. These hold spills for cleanup.
- Secondary containment is mandatory in many jurisdictions for storing hazardous liquids like acids or flammable chemicals.
Labeling
- Clear labeling identifies container contents from a distance. This reduces handling errors.
- Include hazard warnings and chemical names on labels. Color coding also quickly indicates chemical classes.
- Label both the containers and shelving/storage areas. This keeps chemicals segregated and organized.
Following basic safety practices like sealed lids, ventilation, secondary containment, and labeling helps create a responsible storage environment for chemicals and hazardous materials. Prioritizing safety reduces risks to workers, facilities, and the surrounding community.
Sizing and Organization
Choosing the right storage container size is crucial for optimizing your chemical storage. Consider the quantities and types of chemicals you need to store. Larger containers allow storing bulk quantities, while smaller ones are ideal for organizing a variety of chemicals.
Modular and stackable containers provide flexibility in arranging your chemical storage space. Stackable models with interlocking lids help maximize vertical storage. Modular containers with compatible dimensions let you mix and match components. This allows customizing storage to fit the needs of different chemicals and quantities.
Look for storage systems with a range of sizes and modular components to build your ideal setup. Standard sizes like 5 gallon and 55 gallon are commonly available. Make sure to check chemical compatibility for any container material before purchasing. With the right sizing and modularity, you can efficiently organize even large chemical inventories.
Industry Applications
Chemical resistant storage containers have important applications across various industries that use hazardous or reactive chemicals. Proper storage helps protect workers, facilities, and the environment.

Chemical resistant cabinets, jars, and bottles help segregate incompatible chemicals and reduce the risks of leaks or accidental mixing. Proper labeling is also critical for organization and safety. Many labs utilize color coding and hazmat symbols to clearly identify container contents.
Industrial Facilities
Factories, refineries, and other industrial sites rely on chemical resistant containers for handling corrosive or toxic process chemicals. Steel or plastic drums and totes allow bulk storage and transport. Containers must withstand exposure to extremes of temperature, pressure, or other physical hazards. Facilities also need spill containment products like berms and pallets to isolate leaks.
Waste Management
Proper disposal of hazardous wastes requires chemical resistant containers that will not degrade or corrode. Facilities that handle waste must prevent leaks from drums, tanks, or pipelines that could contaminate soil and groundwater. Durable polyethylene, stainless steel, or specialty coated containers are ideal for containing waste acids, solvents, oils, and other chemicals. Secondary containment helps minimize environmental impacts in case of spills.
Regulations
When it comes to chemical storage, organizations must follow strict regulations set forth by agencies like OSHA and the EPA as well as local fire codes. Proper chemical storage is not only vital for safety, but it's the law.
OSHA sets legal requirements for hazard communication, personal protective equipment, employee training, and container labeling. Chemicals must be sorted and stored according to compatibility groups. Corrosive acids cannot be stored near flammable solvents, for example. Access to hazardous storage areas may require special precautions like face shields, gloves, and aprons.
The EPA provides guidance on secondary containment, spill control, and pollution prevention. Certain volumes and types of chemicals require special handling and reporting. Storage containers must meet EPA standards for leakproofness and longevity.
Local fire codes dictate specifics like maximum quantities per cabinet, distance from ignition sources, ventilation needs, spill containment, and fire suppression systems. Flammable chemicals often come with strict volume limits, like no more than 60 gallons per cabinet.
Proper chemical storage is complex, but vitally important. With hazardous materials involved, organizations must take compliance seriously to protect workers, the community, and the environment from harm. Staying up-to-date on evolving regulations is essential.
