What footwear helps prevent slips on wet surfaces?

Use slip-resistant footwear rated for the surfaces and contaminants present, with deep, clean tread. Replace footwear when the tread wears smooth, and add ice cleats for freezing conditions. Footwear is a backup, not a substitute for controlling the surface.

Why are smooth concrete and metal plates so dangerous when wet?

Polished concrete, steel plates, and painted decks have very low friction to begin with, so even a thin film of water, oil, or condensation can drop traction below a safe level. These surfaces need coatings, grating, or mats where they get wet.

Who is responsible for keeping surfaces dry on site?

The employer is responsible for maintaining safe walking-working surfaces. A designated competent person should inspect surfaces before each shift, direct immediate cleanup of spills, and confirm that slip controls are in place.

How accurate is OSHA Scan at detecting wet-surface slip hazards?

OSHA Scan detects wet and contaminated surfaces. It identifies standing water, mud, ice, and fluid spills, evaluates proximity to edges and equipment, and returns the location and the OSHA standard it may relate to.

Wet Surfaces Cause More Slips Than Any Other Job-Site Hazard

The floor that looks safe is often the one that puts a worker down

Water, mud, oil, ice, and hydraulic leaks turn ordinary walking surfaces into fall hazards in seconds. Slips on wet surfaces are one of the most common causes of lost-time injuries, from sprains and fractures to serious head trauma when a worker goes down near an edge or equipment. OSHA Scan analyzes job-site photos to flag wet, slick, and contaminated surfaces so crews can dry, drain, or barricade them before someone falls.

A wet-surface slip hazard is any walking or working surface made slick by water, rain, mud, ice, snow melt, oil, grease, hydraulic fluid, or cleaning products. OSHA requires walking and working surfaces to be kept clean, dry, and free of hazards where feasible, and to be drained or covered when wet conditions cannot be avoided. A slick surface near an edge, ramp, stair, or moving equipment multiplies the danger.
On job sites these hazards appear as rain-soaked plywood decking, muddy entry paths, condensation on steel and concrete, tracked-in water at building entrances, spilled fuel or hydraulic fluid around equipment, and ice on scaffolds and walkways in cold weather. Smooth surfaces like polished concrete, metal plates, and painted decks become dangerously slick with even a thin film of water.
The danger is that wet surfaces often look no different from dry ones until a boot loses traction. A worker carrying a load, turning quickly, or stepping onto a ramp has no warning before the slip. Because the hazard is transient — it appears with weather, spills, and washdowns — a quick photo scan is one of the few reliable ways to catch it in the moment.

What does OSHA require for wet walking surfaces?

OSHA requires walking and working surfaces to be kept clean, dry, and free of hazards where feasible. Where wet conditions cannot be avoided, employers must provide drainage, mats, slip-resistant surfaces, or other means to protect workers, and must remove spills promptly.

What is a safe coefficient of friction for a floor?

OSHA and industry guidance reference a static coefficient of friction of about 0.5 or higher as a reasonable benchmark for slip resistance on level walking surfaces, with higher values recommended for ramps and inclines.

Are wet-floor signs enough to meet OSHA requirements?

Signs are a warning, not a control. They help, but OSHA expects you to eliminate or reduce the hazard by cleaning spills, drying or draining the surface, and using slip-resistant measures. Barricade the area if it cannot be made safe promptly.

How do I handle ice and snow on job-site walkways?

Establish a cold-weather plan: clear and de-ice walkways, stairs, and scaffolds before work, re-treat as conditions change, and provide traction aids. Barricade areas that cannot be de-iced and reroute foot traffic to safer paths.
