Use plastic barrels for solvents and paints, but check chemical compatibility

Plastic barrels are a versatile storage solution for paints and solvents. They are durable, cost-effective, and widely used in industrial settings. When using plastic barrels, it is important to consider chemical compatibility to ensure safe and proper storage.

Plastic barrels are made from high-density polyethylene (HDPE), a type of high-grade plastic known for its strength and durability. HDPE barrels are compatible with a wide range of chemicals, including common industrial solvents such as ethanol, methanol, and hydrogen peroxide. These barrels can also handle corrosive chemical waste and acidic substances without leaking or corroding.

However, not all chemicals are suitable for storage in plastic barrels. It is crucial to check the compatibility of the specific chemicals you intend to store. Some chemicals can react with the plastic, leading to degradation and instability. For example, fuel substances like petrol and diesel can break down plastic over time. In such cases, steel drums are recommended. Additionally, certain hazardous materials may require steel drums due to their higher strength and safety standards.

To ensure compatibility, look for UN-rated plastic barrels specifically designed for industrial use. These barrels undergo testing and are certified to comply with chemical shipping regulations. They are marked with ratings and labels to indicate their suitability for different chemicals. Always refer to the chemical manufacturer's guidelines and consult experts if you have any doubts about the appropriate storage container.

When using plastic barrels for paints and solvents, proper handling and safety measures are essential. Follow relevant guidelines and legislation for filling, storing, and transporting these barrels. This includes using industrial equipment for movement, storing undercover when possible, and securing them safely during transit. Additionally, perform risk assessments and provide adequate personal protective equipment (PPE) for employees to ensure their safety when working with these substances.

Store away from heat, flames, and ignition sources

Storing open barrels of paints and solvents requires caution, especially when dealing with flammable substances. Here are some detailed guidelines for storing these substances away from heat, flames, and ignition sources:

Firstly, it is imperative to identify the type of paint or solvent you are dealing with. Different types of paints have distinct storage requirements. Solvent-based paints, for instance, typically contain flammable materials and fall under stricter storage regulations. Conversely, water-based paints are generally less hazardous and have fewer restrictions. Always refer to the Safety Data Sheet (SDS) provided by the manufacturer to understand the specific properties and storage requirements of the substance you are handling. This sheet will help you identify the flammability and toxicity levels of the product.

Once you have identified the substance's properties, follow these guidelines to store it away from heat, flames, and ignition sources:

  • Keep solvent containers away from any potential ignition sources, including open flames and sparking tools. Be cautious even around hot surfaces like space heaters, as solvent vapours are heavier than air and can travel, potentially igniting from a spark across the room.
  • Store flammable paints and solvents in designated areas that are free from flames and heat sources. In professional settings, solvent-use areas are typically designated as flame-free zones.
  • Ensure that the storage area is well-ventilated to disperse fumes and lower the concentration of vapours in the air.
  • Store flammable paints and solvents in appropriate cabinets or lockers that meet fire protection standards. These storage units should be constructed of fire-resistant materials, such as steel, and bear the signage "Flammable-Keep Away from Open Flames."
  • Consider using explosion-proof electrical items within the storage area, such as exhaust fans, heating, or cooling systems, to mitigate the risk of fire.

By following these guidelines, you can effectively store open barrels of paints and solvents away from heat, flames, and ignition sources, thereby maintaining a safe storage environment.

Use airtight containers to reduce evaporation and fumes

When storing open barrels of paints and solvents, it is important to use airtight containers to prevent evaporation and reduce fumes. This is crucial for both short-term and long-term storage. During active painting periods, it is important to limit the solvent's exposure to open air. Use containers with lids or covers, such as brush washer pots with self-closing lids, to reduce evaporation and lower the concentration of vapours in the air.

For water-based or latex paints, plastic containers with airtight seals are ideal for preventing skimming, drying, or leakage. Look for containers with triple-lock press-fit or snap-on lids, which provide an audible "click" to confirm a secure closure. These containers are also rust-proof, lightweight, and resistant to odours and chemicals.

For oil-based or solvent-based paints, ensure the container is rated for chemical resistance and solvent compatibility. Solvents like turpentine, mineral spirits, and paint thinners require careful storage due to their flammability and volatility. Always keep solvent containers away from ignition sources, such as open flames or hot surfaces.

When storing large volumes of paint, consider using plastic paint cans with gallon capacities. These containers feature triple-lock seal lids that provide an airtight closure, minimising skimming and trapping odours inside. They are made with durable polypropylene, resisting rust, dents, and chemicals.

Additionally, when storing paints and solvents, it is important to minimise the air space in the containers. Transferring partially-filled containers to smaller cans or bottles can slow down the oxidation and evaporation process. This is especially important for solvents like turpentine, which can gradually oxidise and lose effectiveness when exposed to air.

Keep in a cool, dry, and dark location

Keeping open barrels of paints and solvents in a cool, dry, and dark location is crucial for several reasons. Firstly, temperature control is essential to maintain the quality and effectiveness of the materials. Extreme temperatures can negatively impact the paint's consistency, viscosity, and performance. For instance, water-based paints can gel at freezing temperatures, while higher temperatures can cause them to develop an unfavourable consistency.

Secondly, a cool, dry location helps prevent volatile chemical reactions and protects the chemical consistency of the products. This is especially important for oil-based paints containing solvents, which are classified as flammable liquids. By storing them in a cool, dry place, you reduce the risk of fire and ensure compliance with OSHA regulations designed to prevent sudden fires and injuries from toxicity exposure.

Additionally, dryness is essential to avoid issues with electrostatic application, which can compromise the quality of the powder coating and the final product. On the other hand, excessive humidity can cause powder to clump or cake, so a controlled environment is necessary.

Lastly, darkness is important because light can accelerate oxidation, causing resin-containing mediums to yellow or break down over time. Commercial mediums are often packaged in brown glass bottles or metal cans to protect them from light. If you're using a clear jar, store it in a dark drawer or wrap it in aluminium foil for long-term storage.

Use safety cabinets for flammable liquids

When storing open barrels of paints and solvents, it is important to consider the use of safety cabinets, especially if the substances are flammable. Safety cabinets are designed to store flammable liquids and chemicals safely, reducing fire risks and protecting your workplace and employees.

Safety cabinets for flammable liquids are constructed to meet specific standards and regulations, such as OSHA and NFPA requirements. These cabinets are made of sturdy, fire-resistant materials like double-wall welded steel, providing a layer of protection in the event of a fire. The construction also includes insulating air space to reduce the spread of fire and protect the contents. Additionally, the cabinets feature self-closing or self-latching doors to secure the flammable substances and prevent unauthorised access.

The use of safety cabinets allows for the safe storage of flammable liquids near work areas. They come in various sizes, ranging from portable countertop cabinets for small quantities to larger drum cabinets for 30 to 55-gallon drums. You can also find wall-mount cabinets, under-counter cabinets, and stackable piggyback cabinets to maximise space. These cabinets enable you to store flammable liquids within easy reach while maintaining safety standards.

When choosing a safety cabinet, it is important to select the appropriate size and capacity for your needs. Consider the volume of flammable liquids you need to store and choose a cabinet that accommodates that quantity. Additionally, look for features such as leak-proof sumps, which prevent spills and leaks from escaping the cabinet. Drum rollers in some cabinets also make loading and unloading drums of paint easier.

By using safety cabinets for flammable liquids, you can ensure compliance with regulatory requirements, improve workplace safety, and efficiently manage flammable substances. These cabinets are a reliable solution for storing flammable paints and solvents, reducing the risk of fire hazards and providing secure storage.
