This typically involves higher levels of protection, such as respiratory protection with N95 respirators or equivalent, which filter out airborne particles, and blood-borne pathogen protection with gloves, gowns, and face shields or goggles to prevent contact with blood and bodily fluids. Industrial workers face different types of hazards, including chemical exposure, physical injuries, and environmental factors. Their PPE tends to focus on chemical protection with protective suits, gloves, and boots made from materials resistant to specific chemicals or solvents, and physical protection with hard hats, safety glasses, and high-visibility clothing to prevent injuries from machinery or construction sites. The primary hazard in a medical setting is biological agents, such as viruses, bacteria, and other pathogens that may be present in patients' blood or other bodily fluids. Workers in industrial settings face a variety of hazards, including but not limited to chemical exposure from handling toxic substances, physical dangers from heavy machinery and equipment operation, and environmental risks such as extreme temperatures or noise pollution. PPE for medical use often includes features like fluid resistance with materials that are impermeable to liquids to prevent contamination, antimicrobial treatment with some PPE items having an antimicrobial coating to reduce the growth of microorganisms, and compatibility with other medical equipment designed to be used in conjunction with other medical tools and devices without interference. PPE for industrial use emphasizes features like durability with materials that can withstand harsh conditions and repeated use, comfort and mobility often lighter and more flexible materials to allow for ease of movement over long periods, and specialized functionality such as gloves having enhanced grip or shoes having steel toes for added protection against physical impacts.
