Manufacturers supply which type of charts to safely estimate chemical resistance of a garment?

• A. Degradation charts
• B. Compatibility charts
• C. Penetration charts
• D. Chemical competency charts

Answer: (B)

Compatibility charts from the manufacturer show which chemicals a specific garment material can safely resist. They guide you to choose the right fabric (such as nitrile, neoprene, or PVC) for the chemicals you’ll encounter and indicate whether exposure is safe, limited, or not recommended. Degradation charts focus on how a material wears down over time or with exposure, which doesn’t directly tell you if a chemical is compatible with the material. Penetration charts describe whether a chemical can get through the barrier, but the compatibility chart provides the overall suitability for the chemical-material pairing. The term chemical competency chart isn’t a standard resource for PPE selection. So, compatibility charts are the correct resource.
