Slips on wet surfaces are a major safety concern, especially on construction sites where water and other liquids are common. These incidents can result in serious injuries, medical costs, downtime and reduced productivity. In some cases, they can even be fatal. Here we share practical measures construction engineers can adopt to minimise slip hazards and keep workers safe.
Understanding the causes of slips on wet surfaces
Before tackling the problem, engineers must understand what causes slips on construction sites. Wet surfaces reduce friction and cause workers to lose traction. Key causes include:
- Rainfall: Construction sites are often exposed to the elements. Heavy rain frequently creates slippery conditions on surfaces.
- Spills: Water, cement slurry, oil and mud often end up on walkways and work zones during various phases of construction.
- Poor drainage: If the site lacks proper drainage, standing water forms quickly, increasing the risk of slipping.
- Worn-out footwear: Boots with smooth or degraded soles offer little grip, especially in wet conditions.
- Improper surface materials: Some temporary walkways or flooring materials become slick when wet, creating hazardous footing.
- Clutter and debris: When tools, construction materials or equipment obstruct walkways, wetness amplifies the risk of slipping.
Strategies for preventing slips on wet surfaces
Addressing slip hazards requires a multi-layered approach involving engineering and administrative controls, as well as the right protective gear.
1.Modifying the environment
These measures aim to address the hazard at its source by improving the physical layout and design of the worksite:
- Install proper drainage systems: Water must not pool in walkways or work zones. Use site grading, trenches, culverts and pumps to guide water away. Where applicable, guttering and downpipes help redirect rainwater.
- Apply anti-slip coatings: Use textured coatings or anti-slip paint on high-traffic areas like stairs, ramps and walkways. These materials increase surface friction.
- Use slip-resistant materials: Fit high-risk zones with rubber mats or flooring that feature raised patterns and drainage holes. These allow water to run off and keep surfaces dry.
2. Creating safe work practices
Engineering measures alone are not enough. Construction managers must enforce consistent, safe work practices:
- Housekeeping routines: Keep the site clean. Remove debris, tools and materials from walkways, and clean up any spills promptly.
- Plan around the weather: Track forecasts to anticipate rain. Delay non-essential outdoor work during wet conditions to reduce exposure to hazards.
- Use clear signage: Put up warning signs where wet surfaces are present. “Slippery Surface” or “Caution: Wet Floor” notices should be visible and placed in affected areas. Barricading unsafe zones helps prevent unintended access.
3. Personal protective equipment (PPE)
PPE should never be the only control, but it plays a vital role in reducing injuries when other measures fail:
- Wear slip-resistant boots: Workers should use boots designed with rugged, non-slip soles. Regular inspections ensure worn-out footwear is replaced.
- Use gumboots when necessary: In areas prone to flooding or water buildup, gumboots offer extra protection and grip.
- Gloves with grip: Workers handling tools in wet conditions find help from gloves that maintain strong grip.
Importance of a proactive approach to slip prevention
The best way to reduce slip risks is through early planning and continuous monitoring. Investing in drainage, enforcing daily housekeeping and using appropriate PPE ensures that the site remains safe throughout the construction phase. When site managers monitor weather conditions and adapt work schedules accordingly, they can avoid unnecessary exposure to slip risks.
Legal and ethical responsibility
Construction companies have both legal and moral obligations to protect workers. Kenya’s occupational safety regulations require employers to maintain safe working environments. Ignoring known risks such as wet surfaces may result in penalties and expose workers to harm. Beyond compliance, taking steps to prevent slips supports a broader safety culture and boosts morale on site.
