1. Cleanroom Compatibility: not all shoe covers are designed to be worn with a boot cover in a controlled environment. Construction materials determine if the shoe cover will help to reduce or increase contamination in your cleanroom. Uncoated spunbound polypropylene shoe cover is well suited for industrial and hospital settings, however in a cleanroom, it will release fibers. Average operators walk from 700 to 1,000 steps around their work stations. Can you imagine operators wearing cleanroom shoe covers that release particles in every step? The HEPA pre-filters will be choked with polypropylene fiber.
2. Traction and Slip Resistance: The only way to prevent slips and falls is to make sure that shoe covers are well fitted, and provides as much traction and slip resistance as possible. Look for a substrate material with a high co-efficient of friction. The higher the number, the more “anti-slip” the shoe cover will be.
3. Design and Comfort: Is the sole durable? Waterproof? Abrasion resistant? The wrong design can actually increase the risk of costly operator accidents.
