Why This Topic Matters
Wet concrete, mortar, and grout are highly alkaline — caustic enough to cause serious chemical burns to skin and eyes. Because these burns often don’t hurt right away, workers can kneel in wet concrete or have it trapped inside a boot or glove for hours before they notice, and by then the damage can be deep. Cement can also cause allergic skin reactions that last for years.
Concrete burns are almost entirely preventable with the right gloves, boots, eye protection, and clothing, and by washing off wet concrete promptly. Knowing that the burn can develop without pain is what makes the crew take wet concrete seriously.
Presenter Script
“Good morning, everyone. Today’s talk is on concrete burns and cement exposure — because wet concrete can burn you badly, and you might not feel it until it’s too late.
Wet concrete, mortar, and grout are strongly alkaline — caustic, like a chemical. When they stay in contact with skin, they can cause deep chemical burns.
The dangerous part is that these burns often don’t hurt at first. Concrete inside a boot or soaked into your pants while you kneel can be burning you for hours before you notice.
Protect yourself. Wear alkali-resistant gloves, like nitrile or butyl, waterproof boots tall enough to keep concrete out, and tuck or tape your pants so concrete can’t get inside. Use waterproof knee pads when kneeling, and wear safety glasses or goggles.
If concrete gets on your skin, wash it off right away with clean, cool water and a mild soap. If it gets inside your boots or gloves, take them off and rinse your skin — don’t keep working.
If it splashes in your eyes, get to the eyewash immediately and flush for at least 15 minutes, then get medical attention.
Cement can also cause allergic skin reactions over time. And dry cement dust or cutting cured concrete creates dust, including silica — use water, dust controls, and respiratory protection as required.
Respect wet concrete, cover up, and wash it off fast. Thanks, everyone — let’s have a safe day.”
Frequently Asked Questions
Why does wet concrete cause burns?
Portland cement in wet concrete, mortar, and grout forms a strongly alkaline mixture, often around pH 12 to 13. Prolonged contact with skin breaks down tissue, causing chemical burns that can be deep and slow to heal. Moisture, pressure, and friction — such as kneeling or concrete trapped in a boot — make burns worse.
Why don’t concrete burns hurt right away?
Alkaline burns often don’t cause immediate pain the way heat burns do, so damage can build up for hours before a worker notices redness, blistering, or pain. That’s why any concrete on the skin should be washed off right away, even if it doesn’t hurt.
What gloves and boots should be worn?
Use alkali-resistant gloves, such as nitrile or butyl, and waterproof boots tall enough to prevent concrete from getting inside. Tuck or tape pant legs so concrete can’t enter boots, and use waterproof knee pads when kneeling. Cotton or leather gloves can soak up wet concrete and hold it against the skin.
What should I do if concrete gets in my eyes?
Go to an eyewash immediately and flush with clean water for at least 15 minutes, holding the eyelids open, then get medical attention. OSHA requires eye and body flushing facilities where workers may be exposed to injurious corrosive materials (29 CFR 1926.50(g)).
Can cement cause long-term skin problems?
Yes. Repeated contact can cause irritant dermatitis, and some workers develop allergic contact dermatitis, often linked to hexavalent chromium compounds in cement. Once a worker becomes sensitized, even small exposures can cause a reaction. Good gloves and skin care help prevent it.
Does this talk satisfy OSHA training requirements?
No. This talk provides general safety awareness for a toolbox discussion. It does not replace formal, documented training required for the equipment and tasks involved, which should be completed under your employer’s training program and the applicable OSHA standards. The full CrewTalks courses cover these topics in more depth.
