Wet Concrete Hazards Toolbox Talk

Wet concrete is a common jobsite material, but it can cause serious injuries fast. Cement in wet concrete is caustic and can burn skin, damage eyes, and soak through gloves, boots, and clothing without much warning. Crews can also get hurt from slips, trips, and strains while placing, screeding, vibrating, and finishing concrete on uneven, wet, or muddy surfaces.

This talk covers the main hazards of working with wet concrete, what crews need to check before placement starts, and how to protect skin, eyes, and footing while the work is underway. The goal is to catch problems early and keep a routine concrete pour from turning into a medical issue or lost-time injury.

Why This Matters

• Wet concrete can cause chemical burns that may not hurt right away.
• Concrete splashes can seriously injure eyes and lead to permanent damage.
• Soaked gloves, pants, and boots can trap concrete against the skin for hours.
• Wet, slick surfaces around a pour increase the chance of slips and falls.
• Handling hoses, chutes, forms, and tools around fresh concrete adds strain and pinch-point risks.

Common Hazards

• Skin contact with wet concrete through torn gloves, low-cut boots, or soaked clothing.
• Concrete entering boots while walking in slabs, footings, or formed areas.
• Splashes to the face and eyes during chute work, pumping, vibrating, or finishing.
• Slip hazards from wet rebar, muddy grade, slick form edges, and slurry on walking surfaces.
• Manual handling injuries while moving screeds, hoses, forms, and finishing equipment.
• Workers kneeling in fresh concrete without proper waterproof protection.
• Pours during cold or rainy weather when crews may not notice soaked clothing until skin damage has already started.

Safety Checklist

Before Work Begins

• Inspect gloves, boots, sleeves, and eye protection before the pour starts.
• Wear waterproof gloves and boots that are high enough to keep concrete out.
• Use long sleeves, long pants, and other skin coverage that will not let concrete sit against the body.
• Make sure clean water, soap, and wash stations are available for quick cleanup.
• Plan safe access paths around forms, rebar, pump lines, and finishing areas.
• Review who is handling the chute, hose, vibrator, screed, and cleanup work.

During Work

• Wash off any concrete on skin right away. Do not wait until break time.
• Change out gloves, sleeves, pants, or boots if they become soaked or filled with concrete.
• Keep hands away from pinch points at chutes, pump hoses, and forms.
• Walk carefully and keep work areas as clean as possible during placement.
• Use extra caution when stepping over rebar, forms, hoses, and wet surfaces.
• Wear eye protection at all times when concrete can splash.
• Do not kneel, sit, or stand in wet concrete longer than necessary without proper protection.

Crew Talking Points

• Do you have the right gloves and boots for this pour, or are you making do with damaged gear?
• Where will you wash off concrete quickly if it gets inside a glove or boot?
• What are the slickest travel paths around this pour right now?
• Who is watching hose movement, chute swing, and congestion around the placement area?
• Are we rotating tasks if someone is spending long periods kneeling, screeding, or handling the hose?
• Speak up now about any gear problems, access issues, or concerns before placement starts.

Stop Work If

• Concrete gets inside gloves, boots, or clothing and cannot be cleaned out right away.
• Eye protection is missing, damaged, or not being used where splashes are possible.
• Walking or working surfaces become too slick to move safely.
• Crews do not have access to water and a way to wash off exposed skin.
• Pump hose, chute movement, or crew positioning creates a struck-by or pinch-point hazard.
• Anyone reports burning skin, irritation, or eye exposure.

Final Reminder

Wet concrete is not harmless mud. Protect your skin, keep it out of your boots and gloves, and clean it off immediately before a small exposure becomes a serious burn.
