Protective coveralls are full-body suits designed to shield wearers from chemical splashes, infectious agents, particulate matter, and environmental hazards. These garments are widely used in medical, industrial, and hazardous cleanup environments to create a comprehensive barrier between the user and contaminants. Constructed from multilayered, fluid-resistant materials like SMS, microporous film, or Tyvek, these coveralls offer high tensile strength while remaining breathable. They typically feature a hood, full front zipper closure, elastic wrists and ankles, and sometimes boot covers for complete body coverage. Seam sealing and taped zippers are standard in high-protection models, preventing fluid or microbial penetration. In healthcare, coveralls are critical for infection control during disease outbreaks, surgeries, or when handling hazardous biological materials. In industrial settings, they protect workers from paint, asbestos, and chemical exposure. Certified coveralls comply with global safety standards (such as EN 14126 or ISO 16603), indicating resistance levels to blood, viruses, and liquids. Some models come with antistatic properties, flame retardancy, or high-visibility coloring for specialized applications. Reusable and disposable variants are available; disposable ones are discarded after use to prevent contamination, while reusable versions can be laundered and sterilized according to guidelines. Protective coveralls offer all-around defense and are essential PPE in any high-risk work environment, combining safety, durability, and comfort.
