What does a hazmat suit protect against?

A hazmat suit protects against hazardous materials and substances, including:

• Chemical agents – such as acids, toxic gases, or industrial chemicals.
• Biological agents – like bacteria, viruses, and other pathogens.
• Radiological particles – including radioactive dust or contaminated materials.
• Nuclear contamination – typically paired with other protective gear for high-radiation environments.
• Particulate matter – including dust, asbestos, and other fine particles.
• Liquids and vapors – depending on suit level, it can resist permeation from toxic or corrosive substances.

The protection level depends on the suit type (e.g., Level A, B, C, or D), with Level A offering the highest protection including full encapsulation and self-contained breathing apparatus (SCBA).
