## Key takeaways

- InduBarrier™ Type 4B is certified to EN 14605 and ASTM F1671, engineered for liquid-tight protection against pressurized chemical sprays and blood-borne pathogens.
- InduBarrier™ Type 5B is certified to EN 13982-1 and targets dry hazardous particulates and biological aerosols instead of liquid threats.
- Type 5B keeps workers safe in pharmaceutical manufacturing, agricultural pesticide handling, and construction abatement such as asbestos removal, while maintaining thermal comfort during long shifts.

## Frequently asked questions

### What extreme hazardous environments are InduBarrier Type 4B and 5B coveralls designed for?

InduBarrier Type 4B, certified to EN 14605 and ASTM F1671, is engineered for liquid-tight protection against pressurized chemical sprays and blood-borne pathogens, making it suited to biohazard and epidemic response work. Type 5B, certified to EN 13982-1, instead targets dry hazardous particulates and biological aerosols, keeping workers safe in pharmaceutical manufacturing, agricultural pesticide handling, and construction abatement such as asbestos removal, all while maintaining thermal comfort during long shifts.

### How do I choose between InduBarrier™ Type 4B and Type 5B for a specific job?

Choose Type 4B when the hazard involves pressurized liquid chemical sprays or blood-borne pathogens, since it's certified to EN 14605 and ASTM F1671 for liquid-tight protection. Choose Type 5B when the hazard is dry particulates or biological aerosols, such as pharmaceutical powders, pesticide dust, or asbestos abatement, since it's certified to EN 13982-1 for that threat type.
