Open-construction and drainable mats for floors that stay wet. The holes let liquid through so the operator stands above it rather than in it — that is the difference from an anti-fatigue mat, which traps whatever it sits in. Grease-resistant compounds go in kitchens and fryer lines; cutting-fluid-resistant versions go at machining centers where a standard rubber mat breaks down. Disinfectant boot bath and containment mats are here as well, for food and clean-area entrances.
