Q: Can Industrial Worksafe be exposed to liquids?

A: Yes, Industrial Worksafe can be placed in both wet and dry environments.

Q: How do I clean my Industrial Worksafe mat?

A: Use a high-pressure hose (not to exceed 500 psi) and hot water (max 160o F) to rid the mats of oils. For best results use a mild soap or detergent with a pH between 4 and 9, to clean the mats. Do not use steam (unless specifically recommended), degreasers, or caustic chemicals. Do not machine wash or mechanically scrub the mats.

Q: There 2 sides to my mat. Which side do I stand on?

A: The ramps on the top side of the mat are ribbed.

Q: Are the colors shown on your website the exact color I should expect to receive?

A: No, because monitors vary so there may be a slight variance in the color. If color choice is critical, we suggest that you order a sample. Due to manufacturing processes and material dye lots, color can vary, but our products fall within an industry-standard acceptable variation.

Q: Do Industrial Worksafe mats pose a tripping hazard?

A: Industrial Worksafe mats have molded-in safety borders (sloped edge) on all four sides. This allows for a smooth transition on and off the mat and do not pose a tripping hazard.

Q: Do your rubber mats smell?

A: Yes! Unfortunately, that rubbery smell is a feature of any rubber product. The mat should lose that smell over time. If you are planning to install rubber mats or flooring in any enclosed space, please remember that this can slow the dissipation of a strong rubber scent.
