Wet concrete is extremely alkaline; meaning it can cause serious chemical burns if it comes in contact with your skin for even a short period. These burns may not be felt immediately, but damage can continue beneath the skin long after exposure.
Hazards
- Cement paste in wet concrete is corrosive (pH ~12-13).
- Prolonged contact can lead to burns, blisters, ulcers, or long-term skin damage.
- Socks and boots can trap wet concrete, worsening the injury.
- Hands, knees, and forearms are the most affected areas.
Prevention Tips
- Wear Proper PPE:
- Waterproof gloves, long sleeves, and alkali-resistant boots.
- Tuck pants into boots to prevent concrete from entering footwear.
- Avoid Direct Contact:
- Never kneel in fresh concrete without knee protection.
- Use tools, not hands, to move or smooth concrete.
- Change Out Wet Clothes Immediately:
- Wet clothes soaked with concrete should be removed ASAP.
- Wash affected skin with clean water and pH-neutral soap.
- Report & Treat Burns Promptly:
- Early treatment is critical, don’t wait for pain.
- Seek first aid or medical attention if irritation develops.
What to Do If Exposed
- Immediately rinse skin with water for at least 15 minutes.
- Do not neutralize with vinegar or acidit may worsen the injury.
- Notify a supervisor and seek medical help if burns appear.
Safety Check
- Do your gloves and boots meet the job’s protection level?
- Are you aware of where the nearest eyewash station or rinse area is?
Safety Reminder
If it feels wet and gritty, don’t ignore it. Concrete can burn deeper than it looks.
