First Aid for Wet Cement Burns and How to Prevent Them

If wet cement or fresh concrete gets on your skin, stop work and start rinsing immediately with plenty of clean, cool or lukewarm running water. Remove contaminated boots, gloves and clothing so they cannot hold cement against the skin. Have someone arrange urgent medical advice for a suspected burn while you rinse. Start rinsing an eye splash immediately and get emergency medical care.

Cement is the binder in concrete and mortar. Once wet, it is strongly alkaline and can injure tissue without causing much pain at first. A damp patch over a knee or a gritty trickle inside a boot is reason enough to stop and wash. Waiting until it stings gives the cement more time against the skin.

First aid when wet cement gets on skin

Take the person away from the wet mix and direct them to clean running water. A helper should protect their own hands from the cement. Getting the material off and calling for help can happen at the same time.

1. Remove the source. Carefully take off contaminated items as rinsing begins. Check socks, cuffs and trouser knees as well as the obvious splash. If the material on the skin is still a loose, dry powder, carefully brush it off first before rinsing. For wet paste or slurry, start the water immediately.
2. Keep the water running. Use clean water and allow it to run off the affected area. In the US, Poison Control’s cement-specific advice is to rinse exposed skin for at least 15 minutes and get guidance from a poison center. UK NHS advice for a chemical burn is to call 999 and irrigate with cool or lukewarm water for about an hour. Follow local emergency advice and keep rinsing while help is arranged.
3. Leave other products off the burn. Avoid creams, ointments and attempts to neutralize cement with vinegar or another chemical. A burned area needs medical assessment. It can continue to change after the visible material has been washed away.

Tell the medical team which product was involved, where it touched, how long it may have remained on the skin and when washing began. Someone else can find the product label or safety data sheet while first aid continues. See US Poison Control’s guidance on cement exposure and NHS first aid for chemical burns.

What to do if cement splashes into an eye

Go straight to the nearest emergency eyewash station or use a source of clean water immediately. Hold the eyelids open and use a gentle flow. The UK NHS advises washing the eye with plenty of water for at least 20 minutes. Remove contact lenses if they come out easily while rinsing. Keep flushing the eye as another person arranges emergency medical care. Avoid rubbing the eye or trying to pick out particles.

A chemical splash in the eye needs urgent attention even if vision seems clear at first. Have a coworker bring the product information to the medical team. The NHS advice on chemical eye injuries explains how to rinse while waiting for help.

Recognize a cement burn even when it barely hurts

Look at where wet material could have stayed in contact with skin. The tops of boots, backs of gloves and knees of wet trousers are easy places to miss. Early irritation may be mild. Blisters, hardened skin or an open sore can develop as the injury deepens. The time spent in wet clothing and the location of the contact matter when describing an exposure to a clinician. OSHA describes the delayed warning signs of Portland cement burns.

A Washington State workplace injury report describes a concrete finisher whose work boots let wet concrete soak through. Cement also reached the skin above his gloves. He sustained second-degree burns to both feet, ankles and wrists, spent a week in hospital and missed more than a month of work. The injury locations show why the top of a glove and the material of a boot deserve as much attention as whether the worker is wearing them. Read the Washington State injury investigation.

Keep wet cement out of boots, gloves and clothing

Before the pour, walk the tasks that bring workers into contact with the mix. Placing, screeding, kneeling to finish edges and cleaning tools expose different parts of the body. The supervisor should provide a way to do each task with less contact, then check that the protection suits the remaining exposure.

• Plan the working position. Minimize time kneeling in fresh concrete. Use a suitable knee board or waterproof knee protection for screeding, and check that liquid cannot soak through the trousers underneath.
• Check boots and cuffs together. Choose liquid-tight boots high enough for the task. Wear trousers over the boot tops so splashes drain outside. Replace damaged boots and have clean, dry clothing available if a splash gets inside.
• Choose gloves for the mix. Use waterproof, alkali-resistant gloves suited to the task and its duration. Check fit at the wrist and the condition of the lining. Change a contaminated glove and wash the hand before putting on a clean one.
• Set up washing before work starts. Locate clean running water close to the pour and keep the route clear. Provide washing facilities large enough for forearms, emergency eyewash where splashes are possible, and showers where people may be heavily contaminated. Water used to wash tools or chutes is unsuitable for first aid.

After a splash, check how the mix reached the worker before restarting the task. Replacing wet socks deals with the immediate contamination. Changing the boot, trouser overlap or working position can prevent the same exposure on the next pour. The UK Health and Safety Executive gives task-specific controls for cement on construction sites.
