Chemical-resistant protective clothing (CRPC) is a critical piece of PPE for workers exposed to hazardous chemicals, including acids, alkalis, solvents, and toxic substances. Used in industries such as chemical manufacturing, pharmaceuticals, oil and gas, and waste management, CRPC is designed to prevent skin contact with harmful chemicals, which can cause burns, irritation, or long-term health issues. However, even the highest-quality CRPC will fail to protect workers if it is not handled, worn, and removed properly. This guide outlines the key steps for the correct use of chemical-resistant protective clothing to ensure maximum safety.
First, it is essential to select the right type of CRPC for the specific chemical hazard. Different chemicals require different levels of protection, and CRPC is rated based on its resistance to specific substances. Before using CRPC, workers should consult the manufacturer's guidelines and the safety data sheet (SDS) for the chemical being handled to ensure the clothing is compatible. For example, neoprene gloves are resistant to oils and solvents but may not protect against strong acids, while butyl rubber is ideal for protection against acids and alkalis. Using the wrong type of CRPC can lead to chemical penetration and skin exposure.
Proper donning (putting on) of CRPC is equally important. Before putting on the clothing, workers should inspect it for any signs of damage, such as tears, holes, or worn seams-even small damages can allow chemicals to seep through. Workers should also remove any jewelry, watches, or other accessories that could tear the clothing or create gaps. When putting on CRPC, start with the gloves, then the suit or apron, followed by the boots (if integrated) and hood (if applicable). Ensure that all openings-such as cuffs, neck, and waist-are sealed tightly to prevent chemical exposure. Some CRPC comes with Velcro closures or elastic bands to help create a secure seal.
During use, workers should avoid unnecessary movement that could strain or tear the clothing. They should also avoid touching contaminated surfaces with their gloved hands, as this can transfer chemicals to other parts of the body or the clothing. If the CRPC becomes contaminated with chemicals, workers should immediately move to a safe area and follow the decontamination procedure outlined by their employer. Decontamination typically involves removing the contaminated clothing, washing the skin with soap and water, and disposing of or cleaning the CRPC properly.
Proper doffing (removing) of CRPC is critical to avoid self-contamination. Workers should start by removing the gloves first, taking care to peel them off from the wrist (turning them inside out) to avoid touching the contaminated outer surface. Next, remove the hood (if applicable), followed by the suit or apron, and then the boots. All contaminated CRPC should be placed in a designated container for cleaning or disposal, depending on the type of chemical and the manufacturer's instructions. After doffing, workers should wash their hands thoroughly with soap and water, even if they wore gloves.
Regular training is essential to ensure workers understand how to select, wear, and remove CRPC correctly. Employers should also conduct regular inspections of CRPC to ensure it is in good condition and replace any damaged or worn clothing immediately. By following these guidelines, workers can significantly reduce their risk of chemical exposure and ensure that CRPC provides the maximum level of protection.
