How to Store Flammable Products in a Retail Store
Flammable and combustible liquids are the cause of over 51000 house fires annually in the United States resulting in 168 fatalities on average per year (OSHA Outreach Courses). Even in a retail store, the same combustible liquids pose a serious hazard to employees and customers as these substances require special storage rather than being placed on a shelf with other retail products. One of the easiest ways for a retail store to improve its safety and liability status is to get to know the federal regulations and develop storage habits accordingly.
What Is Considered Flammable in a Retail Setting
The flash point determines the flammability of a substance, which is the temperature at which vapors from the substance can be ignited. According to OSHA, flammable liquids have a flash point of below 199.4 degrees Fahrenheit and further divided into categories depending on the level of combustibility (OSHA Outreach Courses). In a retail setting, one can find various flammable liquids such as butane, lighter fluid, aerosol sprays, adhesives, and specific cleaning agents among others. Even though the liquid itself is highly combustible, it is the vapors that present an acute hazard, which is why proper storage facilities are essential to avoid ignition (OSHA Outreach Courses). Thus, the flammable liquids in retail settings require special storage facilities separate from any open flame.
Storage Requirements for Flammable Liquids in a Retail Store
Several OSHA standards apply to the storage of flammable liquids, including 29 CFR 1910.106, which explicitly addresses mercantile occupancies, otherwise termed retail stores (OSHA). According to OSHA standards, retail stores must store flammable liquid in closed metal containers in an approved cabinet or inside a storage room that is inaccessible to the general public (OSHA). The general rule is no more than 25 gallons of flammable liquids are to be stored outside of an approved cabinets in a given area, and no more than 60 gallons of flammable liquids can be in a chemical storage container in the retail store (U.S. Hazmat Storage). If a retail store has a storage room with a door, then it would be possible to store an unlimited amount of flammable liquids as long as all applicable rules are followed.
Approved Storage Cabinet Standards
A storage cabinet is not an approved flammable storage cabinet just because it is made of metal. According to OSHA standards, approved cabinets must be made of 18-gauge sheet steel, constructed using double walls, and only reach a temperature of no higher than 325 degrees Fahrenheit during a 10-minute fire test (U.S. Hazmat Storage). Furthermore, storage cabinets must have a three-point locking system, and doors must have a sill that is at least two inches above the cabinet floor to prevent liquid accumulation in the cabinet (U.S. Hazmat Storage). When shopping for a storage cabinet, always ask the manufacturer to provide documentation regarding the specifications of a cabinet.
Signage and Storage Labeling Standards for Flammable Liquids
Anyone working with flammable liquids must remember to post required signs indicating that storage cabinets contain flammable liquids and must be kept away from an open flame. Signs must be at least two inches tall with the word "FLAMMABLE" and one inch with the words "KEEP FIRE AWAY" with no exceptions (U.S. Hazmat Storage). Items in a storage cabinet or facility, as well as materials, must be organized according to their category rather than alphabetically, as some materials present a higher hazard than others, despite being flammable (U.S. Hazmat Storage). As a retail store professional, it is essential to keep safety data sheets available for any flammable products present on the store’s property because it is one of the documents inspectors and insurance representatives look at upon visiting a retail store.
Storage in Approved Safety Cans
When handling smaller amounts of flammable liquids, there is an option to use safety cans designed to hold up to 5 gallons of liquid and constructed in a way to withstand the pressure exerted on the can by the vapors of a liquid with a flashpoint at 80 degrees Fahrenheit or below(Justrite). When using safety cans, remember that liquids at or below 80 degrees Fahrenheit must be stored in red cans with yellow bands indicating the flashpoint (Justrite). Thus, one can identify an approved safety can for lower-flashpoint liquids by the specific color of the can and the presence of a yellow stripe.
General Storage Tips for Flammable Products in a Retail Setting
One should always store flammable liquids away from heat sources, including sunlight and other sources of heat such as space heaters and electrical equipment.
Remember to follow local storage requirements, including the number of gallons that can be stored in a specific area. If a certain area reaches the limit of the number of gallons that can be stored there, arrange to move the extra bottles to the storage room rather than doubling up in the same area.
Always check the containers for defects, including cracks, leaks, dents, and other issues, and remove defective products from the shelves. Ensure your employees are trained to handle flammable liquids safely and remember that OSHA hazard communication standards require you to train your employees about the hazards presented by the products they handle, although specific training guidelines for flammable liquids do not apply (J. J. Keller). Choose your suppliers wisely as some manufacturers provide better documentation concerning the products, such as storing butane refills and torch lighters from Variety Lighters as an example, which in turn makes storing and handling these products significantly safer.
Conclusion
In a retail setting, the storage of flammable products is a rather complex issue that requires an in-depth understanding of the requirements applicable to a retail store. Although the storage of flammable liquids is not particularly difficult, the combination of the size limits of approved storage cabinets, specific requirements for storage cabinets, appropriate signage, and storage of smaller containers in safety cans present an acute hazard if not followed. By developing habits related to the safe storage and handling of flammable products, a retail store professional can significantly improve the safety of both employees and customers while also protecting the business itself.
