Your secondary containment system must be able to hold a volume greater than or equal to 110% of the largest tank or storage container and cover at least the entire surface under each dry-cleaning machine, tank or container. Wet chemical spaces and those with a higher degree of hazard should be separated from other spaces by a wall or protective barrier wherever possible. NFPA 30 doesnt discuss transfer areas, but requires containment areas to be liquidtight (A.9.13) It also mentions that the authority having jurisdiction needs to deem the area to be acceptable, so sealing the concrete could certainly be deemed an acceptable practice. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. If there is a potential for incompatible chemicals to mix on their way to treatment, if there are corrosives that would damage pipelines, or if there is any other situation that would cause a safety or environmental emergency while the spill was traveling from the drain to the treatment facility, secondary containment may be necessary. Ventilation systems should be inspected and maintained on a regular basis. . Determine the physical and health hazards associated with chemicals before working with them. While its one thing to know what containment is in terms of chemical storage, lets delve a bit deeper to understand exactly WHY they exist. This letter constitutes OSHAs interpretation only of the requirements discussed and may not be applicable to issues not delineated within your original correspondence. Thank you for your interest in occupational safety and health. In hazardous chemical storage, the risk of chemical spills or leaks poses both an environmental threat and one to your employees. Its not so much an exemption as it is a different way of approaching a regulatory requirement. The air in chemical laboratories should be continuously replaced so that concentrations of odoriferous or toxic substances do not increase during the workday. In case the primary container fails, then as per the EPA regulations, it is essential to have secondary containment systems in place. Owners or operators must ensure each bulk storage container meets the requirements in 112.8(c)(2), either individually or as part of a bulk storage container installation. The types of measures that may be used to protect employees (listed from most effective to least effective) are: engineering controls, administrative controls, work practices, and PPE. Liquid Handling The handling of hazardous liquids is subject to both safety and health regulations requiring protection for employees who work with flammable, combustible . The Resource Conservation and Recovery Act (RCRA) requires containment and secondary containment systems, codified in Title 40 Code of Federal Regulations (CFR) Part 264. Know who to notify in the event of an emergency. Information should be clearly posted indicating who to contact in the event of an emergency. If the areas cannot be separated, then workers in lower hazard spaces may require additional protection from the hazards in connected spaces. Waste management workers should be trained in proper waste handling procedures as well as contingency planning and emergency response. Follow all pertinent safety rules when working in the laboratory to set an example. For many of EPAs regulations, secondary containment is just that: a best management practice, rather than a strict requirement. Our solutions are designed to prevent the accidental release of harmful materials, ensuring compliance with regulations and reducing the risk of costly cleanup and liability. Such reactions can happen spontaneously and can produce pressures, gases, and fumes that are hazardous. Institute a Chemical Hygiene Program A comprehensive chemical hygiene program is required.
