Storing pesticides properly is critical for safety, compliance, and effectiveness. Mishandling can lead to accidents, contamination, and legal penalties. Here’s what you need to know:
- Follow Federal and State Laws: Regulations (like FIFRA) require pesticides to be stored according to label instructions. Non-compliance can lead to hefty fines.
- Design a Safe Storage Facility: Choose a location away from water sources, use spill containment systems, and ensure proper ventilation and temperature control (40–90°F).
- Store Correctly: Keep pesticides in original containers, seal them tightly, and organize by hazard type. Use a first-in, first-out system to manage inventory.
- Emergency Preparedness: Have spill kits, protective gear, and an emergency plan ready. Train staff on safety protocols and reporting requirements.
- Training and Certification: Applicators must be certified and stay updated through continuing education programs.
Safe storage isn’t just about rules – it protects your health, community, and business. Start with secure facilities, proper handling, and ongoing education to minimize risks.
Storing Pesticides Properly
Legal Requirements for Pesticide Storage
Pesticide storage is closely regulated at federal, state, and local levels to ensure safety and compliance. Understanding these regulations is essential to avoid penalties and maintain safe practices. Below, we break down the key legal requirements.
Federal Regulations and FIFRA Compliance
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is the primary law governing pesticide regulation in the U.S. It mandates that all pesticides be registered with the EPA and that users strictly follow the storage instructions provided on the product label. As the EPA puts it:
"It has been said that ‘The label is the law.’ This means that using a pesticide in a manner that is inconsistent with the use directions on the label is a violation of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and can result in enforcement actions to correct the violations."
Failing to comply with FIFRA can lead to severe penalties. For instance, in December 2022, a pesticide facility in Idaho faced a $144,400 fine for violations. Ed Kowalski, director of EPA Region 10’s Enforcement and Compliance Assurance Division, highlighted the importance of proper storage:
"Pesticide facilities have an obligation to ensure their products are safely stored to prevent dangerous exposure to employees and surrounding communities. If an accidental release occurs, these chemicals could affect people’s health and harm the environment. When companies comply with environmental regulations, they’re better equipped to prevent and safely handle any potential release."
State and Local Regulations
In addition to federal laws, state and local authorities impose their own rules, which can include permits, inspections, and facility-specific criteria. Local ordinances may also address fire codes, building codes, and zoning requirements, which dictate where and how pesticides can be stored. To ensure compliance, it’s a good idea to consult your state pesticide regulatory agency or organizations like the Association of American Pesticide Control Officials (AAPCO) and the National Pesticide Information Center (NPIC) for detailed state-specific guidelines. Local agencies, such as fire departments and zoning offices, can also provide guidance on meeting regional standards.
Labeling and Certification Requirements
Pesticide labels are your go-to resource for proper storage instructions. These labels, developed by manufacturers and approved by the EPA, provide critical details such as ingredients, toxicity warnings, precautionary measures, and storage and disposal guidelines. Always read the label and review the accompanying Safety Data Sheet (SDS) to ensure compliance with safe storage practices. Following these instructions can help prevent costly errors and ensure the safe use of pesticides.
Beyond labeling, applicator certification requirements vary by state. These certifications typically require training and documentation to confirm that individuals handling pesticides understand safe storage and application practices. Checking both the product label and the SDS is essential for comprehensive storage guidance.
Next, we’ll discuss how to design and locate a pesticide storage facility to meet these legal requirements while prioritizing safety.
Building and Locating a Pesticide Storage Facility
Once you’re familiar with the legal requirements, the next step is to carefully select a location and design a facility that prioritizes safety and compliance. A poorly chosen site or inadequate design can lead to serious issues like contamination, regulatory penalties, and safety risks.
Site Selection and Location
Choosing the right location for your pesticide storage facility is essential to prevent contamination and ensure easy access during emergencies. Regulations require that these facilities be at least 100 feet away from surface waters, wellheads, public water supplies, animal feeding areas, food or feed storage, and residential buildings. To reduce fire hazards, maintain a minimum distance of 50 feet from other structures.
The site should also minimize risks like runoff and water contamination. Pay attention to prevailing wind directions – this can influence how spills or fumes spread in case of an incident. Avoid areas prone to flooding, such as floodplains, ditches, or near ponds, to reduce risks tied to water-related accidents.
Accessibility is another key factor. The site should allow for smooth deliveries and emergency access. If flexibility is a concern, portable or prefabricated buildings are a great option, as they can be relocated if needed due to flooding risks or operational changes.
Before starting construction, consult your local Fire Marshall or Fire Prevention Inspector to ensure your plans meet safety standards.
Building Design and Safety Features
Once the site is selected, the facility’s design must focus on safety and compliance. Incorporate features that protect people, the environment, and the pesticides themselves.
Elevate the storage area at least 12 inches above ground level to prevent moisture issues. Use sealed concrete or another non-porous material for the flooring to stop chemicals from seeping in and to make cleanups easier. Install a 2- to 4-inch barrier around the storage area to contain spills.
Spill containment is a critical aspect of facility design. Following several pesticide runoff incidents in 2024 that caused environmental harm and public health concerns, the EPA updated its requirements in January 2025. Facilities must now include secondary containment capable of holding at least 110% of the volume of the largest container stored on-site [EPA Requirements for Pesticide Storage, January 30, 2025].
Floor drains should either be sealed off completely or connected to a separate holding tank to prevent contaminated water from entering storm drains or groundwater. Never allow drainage from pesticide storage areas to flow into municipal systems.
Ventilation is another must-have feature to prevent harmful vapor buildup and maintain safe air quality. Temperature control is equally important to ensure that chemicals remain effective and stable.
Security and Warning Signs
Once the physical structure is in place, it’s essential to secure the facility and clearly communicate potential hazards. Use strong locks, restricted access systems, and physical barriers to limit entry. The level of security should match the risks based on your location and the types of chemicals stored.
Post weatherproof warning signs that clearly identify the area as a pesticide storage facility and highlight potential dangers. These signs should be highly visible to anyone approaching the building. Implement access controls like locks and logging systems to track who enters the facility and when. This not only enhances security but also helps with inventory tracking and compliance. Limit access to trained personnel only, ensuring they are familiar with safety protocols.
Emergency information should be displayed prominently near the entrance. Include contact numbers for emergency services, poison control, and facility managers, as well as evacuation routes and emergency procedures.
Security measures aren’t just about preventing theft – they’re about minimizing accidents and ensuring that only qualified individuals handle these hazardous materials. A well-thought-out security system protects your investment, safeguards your community, and keeps you compliant with regulations.
The foundation of effective pesticide storage lies in careful site selection and thoughtful facility design. These steps set the stage for safe inventory management and efficient emergency response.
Safe Methods for Storing Pesticides
Setting up a secure storage facility is just the first step; how you store pesticides inside that facility is equally important. Proper storage not only ensures the chemicals remain effective but also keeps everyone safe and helps meet regulatory requirements. Here’s how you can optimize pesticide storage for safety and compliance.
Proper Container Use and Care
Always store pesticides in their original containers. These containers are specially designed for the chemical they hold and include labels with essential safety and usage instructions.
Keep containers tightly sealed when not in use. Even brief exposure to air can cause chemicals to degrade or release harmful vapors. To avoid moisture-related issues, such as corrosion, place containers on pallets or shelves rather than directly on the floor.
If a container becomes damaged, act quickly. Transfer the contents to another container that originally held the same material and still has its proper label. Alternatively, use secondary containment to prevent leaks or spills.
Organize your storage area by grouping chemicals based on their hazard type and purpose. For example, keep flammable pesticides separate from others, and store insecticides and herbicides in distinct sections. Additionally, dry pesticides should be stored apart from liquids to avoid cross-contamination in case of spills.
Temperature and Climate Control
Temperature plays a big role in pesticide storage. Check the label for specific temperature requirements, which often fall between 40°F and 90°F. Ideally, store pesticides in a range of 50°F to 77°F (10°C to 25°C) to reduce the risk of chemical breakdown or the formation of hazardous byproducts.
As Redi National Pest Eliminators explains:
Temperature regulation is a critical factor in the safe storage of pesticides. Pesticides often have specific storage requirements that optimize their efficacy and minimize the risk of hazardous degradation.
High temperatures can accelerate chemical deterioration, potentially making the pesticides both less effective and more dangerous. In extreme heat, pressure may build up inside containers, increasing the risk of leaks or even explosions. On the other hand, freezing temperatures can cause certain formulations, like emulsifiable pesticides, to separate or become unusable.
Humidity is another important factor. Aim to maintain a relative humidity between 30% and 50%. Excess moisture can cause clumping and degradation, while very low humidity might reduce the effectiveness of some products.
To ensure stable conditions, use thermostats and temperature monitors, and install hygrometers to track humidity levels. Good ventilation is also crucial for controlling temperature, reducing humidity, and preventing the buildup of harmful vapors. Lastly, protect pesticides from direct sunlight by storing them in opaque containers or away from windows.
Inventory Management
Keeping track of your pesticide inventory helps maintain safety, reduce waste, and stay compliant with regulations. Start by purchasing only what you need, taking into account your storage capacity, the shelf life of the products, and any potential hazards. While buying in bulk may seem economical, it can lead to expired products and storage issues.
Use a "first-in, first-out" (FIFO) system to ensure older pesticides are used before newer ones. Mark containers with the purchase date when they arrive and note the opening date before storing them.
Maintain a detailed inventory that includes each product’s name, purchase date, quantity, and storage location. Regularly inspect the storage area for any leaks, damage, or missing items. Check expiration dates frequently and prioritize using products nearing the end of their shelf life.
If you have unused, unopened containers, consider returning them to the dealer to reduce storage demands and disposal costs. Keep a copy of your storage facility’s map, floor plan, and current inventory in a secure location outside the storage area. This information can be critical for emergency responders if access to the storage area is restricted.

Emergency Planning and Protection
Emergencies can happen at any time. While secure storage practices are essential, having a solid emergency plan in place ensures the safety of both workers and nearby communities. This includes preparing for potential incidents like spills, fires, or explosions that could occur in your pesticide storage facility.
Spill Containment and Protection
Spill containment is a critical part of any emergency plan. A secondary containment system must be capable of holding the required volume of hazardous materials in case of a spill. Options for containment include spill decks, sloped floors, dikes, concrete walls, and berms. When choosing materials, consider the types of pesticides you’re storing. For example:
- Polyethylene containment works well for corrosive or reactive chemicals and is often more affordable than steel.
- Steel containment is better for fuels, solvents, and flammable liquids because it can be grounded to prevent static buildup.
Make sure your containment system is compatible with the chemicals you’re storing. Place trays directly under containers to catch any leaks. Regular inspections are essential – look for signs of leaks, structural damage, or wear, and address any issues immediately. Documenting these inspections can help you stay ahead of potential problems.
Your facility should also be equipped with spill kits that include absorbent materials, a shovel, and a container for contaminated waste. Store these kits outside the main storage area but close enough for quick access. Additionally, maintain an updated inventory of all stored pesticides, along with maps and floor plans of the storage area, in a secure location away from the facility. Once containment measures are in place, focus on creating a coordinated response plan for emergencies.
Emergency Response Planning
A strong emergency response plan should cover scenarios ranging from minor spills to major incidents, with clear steps for each situation. Start by identifying key emergency contacts and defining procedures for different types of emergencies. For large spills, you can contact CHEMTREC at 1-800-424-9300 for expert guidance.
Training is essential – ensure all staff are familiar with storage safety protocols and know how to respond to accidents. Emergency supplies and personal protective equipment (PPE) should be readily available. This includes respirators, gloves, eye protection, boots, and protective suits. Each storage site should also have clean water, soap for decontamination, and an easily accessible eyewash station. Refer to the Safety Data Sheet (SDS) for specific instructions on handling hazardous spills.
Federal and state regulations often require reporting pesticide spills involving hazardous or extremely hazardous substances. You may also need to notify your Local Emergency Planning Committee (LEPC). Include these reporting requirements in your emergency plan, review it annually, and collaborate with your local fire department to ensure first responders understand the risks involved.
Fire Safety Measures
Preventing fires starts with smart storage and handling practices. Keep flammable pesticides away from heat sources and open flames. Avoid storing combustible materials near steam lines, heating systems, or in direct sunlight, especially if they’re in glass or pressurized containers.
A clean storage area is a safer one. Remove debris like paper, rags, or cardboard that could ignite, and clean up spills immediately to prevent the accumulation of flammable substances. Ensure that a fire extinguisher rated for chemical fires is easily accessible at all times.
Your fire response plan should include evacuation procedures, emergency contact information, and details about the pesticides stored on-site. Share a floor plan and Material Safety Data Sheets (MSDS) for all chemicals with your local fire department. Using resources like the National Fire Protection Association (NFPA) Hazard Identification System can help first responders understand the specific risks they may face.
If a fire occurs, evacuate the area immediately and inform the fire department about the chemicals involved. Set up a security perimeter, and if heavy smoke is present, evacuate people and animals downwind. For minor fires, responders may use fog, foam, or dry powder extinguishers. Water should only be used as a fine spray when absolutely necessary, and any runoff or spilled chemicals must be contained to prevent further contamination.
Training and Education for Pesticide Applicators
Safe pesticide storage and handling hinge on proper training. Well-trained applicators not only comply with regulations but also minimize risks to people and the environment. Federal law requires anyone applying or supervising the use of restricted use pesticides (RUPs) to be certified. This certification ensures applicators understand how to use and store pesticides responsibly, preventing accidents and environmental damage.
The Environmental Protection Agency (EPA) sets minimum competency standards for pesticide applicators, but the certification process is managed by states, territories, and tribal authorities. Many states enforce stricter requirements than federal guidelines, making certification a critical step for all applicators.
Required Training and Certification
To meet certification requirements, applicators should contact their state’s certifying agency. Most states offer a Pesticide Safety Education Program that includes essential training materials. Certification programs typically cover topics like safe storage practices, proper container handling, emergency procedures, and regulatory compliance.
State-specific requirements can vary widely. For instance, in Illinois, individuals applying restricted use pesticides – or any pesticides as part of their job – must obtain a pesticide license. The Illinois Department of Agriculture oversees certification and licensing for outdoor and agricultural pesticide applications. In this state, a commercial applicator’s license costs $240 for a 3-year term, while a private applicator’s license is $60 for 3 years. Commercial applicators must also provide proof of insurance with adequate coverage.
Recent regulatory updates have raised training standards. The EPA revised the Certification of Pesticide Applicators rule, focusing on improving competency, protecting noncertified applicators, and introducing a minimum age requirement.
After initial certification, staying updated through ongoing training is essential to keep up with changing safety standards and regulations.
Continued Education and Recertification
Pesticide applicators must recertify every 3–5 years by completing continuing education courses. These courses ensure that professionals stay informed about updated regulations, safety protocols, and best practices.
Online training has made recertification more convenient. Many state-approved programs now offer flexible learning options accessible on various devices, allowing applicators to complete courses at their own pace. Certificates can often be downloaded immediately after course completion. Some online providers even handle reporting to the Department of Agriculture, saving time and reducing administrative tasks.
For example, Online Pest Control Courses provides state-approved training and recertification options. Their courses, which include CEUs, CCUs, and credits, cover essential topics like pesticide laws, formulations, environmental considerations, and pest management. These are all critical for ensuring safe pesticide storage and handling.
When choosing a continuing education provider, make sure their courses are state-approved and meet your specific licensing requirements. Check with your state’s Department of Agriculture or regulatory agency for a list of approved providers. Some programs even offer courses in Spanish to accommodate a diverse workforce.
Investing in ongoing education not only enhances safety and reduces liability but also boosts professional credibility. Trained applicators are better prepared to maintain safe storage facilities, handle emergencies effectively, and comply with changing regulations over the long term.
