How to safely store full-closed chemical suits when not in use?

Before storing a full-closed chemical suit, it is imperative to ensure it has been thoroughly cleaned and decontaminated after its last use. Proper decontamination removes any residual chemicals or hazardous materials that may have accumulated during use. Failing to remove these substances can lead to material degradation, corrosion, or exposure risks to personnel who handle the suit in the future. The decontamination process should be completed according to industry standards and manufacturer guidelines, and once the suit has been fully cleaned, it should be allowed to dry completely. Storing a wet or contaminated suit can promote the growth of bacteria, mold, and mildew, potentially compromising the material’s integrity or leading to harmful exposure during subsequent use.

Prior to storage, each full-closed chemical suit should undergo a comprehensive inspection to check for any signs of wear, damage, or degradation. Key areas to inspect include the seams, zippers, gaskets, and closures, as well as the overall integrity of the fabric. Any tears, punctures, abrasions, or loose seams should be immediately addressed. Damage to any part of the suit, particularly seals and zippers, can compromise its ability to offer full protection during the next use. It’s crucial to repair or replace any defective suits before they are stored, as further degradation can occur over time if the suit is not in perfect condition. Suits showing signs of wear should be flagged for additional testing or disposal if they are deemed unsafe for future use.

Full-closed chemical suits must be stored in an environment that is clean, dry, and climate-controlled. Extreme environmental conditions can severely impact the protective properties of the suits. Excessive heat can weaken certain suit materials, making them brittle, while cold temperatures can cause some components, such as seals and gaskets, to lose their flexibility. Direct sunlight should be avoided, as ultraviolet (UV) rays can degrade certain synthetic fibers and cause premature aging of the suit. An ideal storage environment maintains a temperature range of 10°C to 25°C (50°F to 77°F), with low humidity levels to prevent moisture accumulation. Excessive moisture in the storage area can lead to mold growth or material degradation, which not only affects the suit’s usability but also creates a hazardous environment for workers. It is essential to ensure that the storage area is well-ventilated to maintain a stable climate and prevent any buildup of moisture or fumes.

The storage area for full-closed chemical suits should be free from any chemical fumes, liquids, or contaminants that could affect the suits. Storage near hazardous substances, solvents, oils, or corrosive chemicals can compromise the integrity of the suit material over time. Chemical fumes, even in low concentrations, can react with the suit’s components, potentially weakening its protective properties or leading to material breakdown. As such, the storage environment should be located away from active chemical processing or industrial areas where cross-contamination could occur. Using enclosed cabinets or lockers specifically designed for storing PPE can provide an additional layer of protection from environmental contaminants.
