Toolbox Talk: PPE: Wet Concrete

| |
CPWR - The Center for Construction Research and Training

Summary Statement

The CPWR Toolbox Talk on Wet Concrete addresses the risk of burns and skin irritation associated with working near wet concrete. The resource includes a ‘real-life’ case example, steps to prevent a related injury or illness, and questions for discussion. It includes an image (page 2) that illustrates the hazard, which can be posted in a central location as a reminder of steps to work safely.   Click on the following links to access the English version and the Spanish version.

CPWR Toolbox Talk logoWet concrete that is thoroughly and quickly washed off the skin will cause little irritation. But continuous contact between skin and wet concrete allows alkaline compounds to burn the skin. These exposures can lead to irritant or even contact dermatitis conditions such as stinging pain, itching, blisters, scabs, dead skin and swelling.

Here is an Example

A construction worker had been laboring on a project for approximately a month. His responsibilities included mixing the wet concrete. His supervisor never supplied him with gloves and boots, and he never requested any safety equipment. By the end of the month he had several burn marks on his hands. After going to the doctor, he discovered that his injuries were so bad that he could not work for a few months until his wounds properly healed.

  1. What could the construction worker have done to avoid the injury caused by contact with wet concrete?
  2. Do you work with wet concrete? What do you do to protect yourself?

Preventing Injuries from Wet Concrete

Personal Protection

To protect skin from cement and cement mixtures, workers should wear:

  • Coveralls with long sleeves and full-length trousers
  • Waterproof boots high enough to prevent concrete from flowing in when standing in fresh concrete
  • Alkali-resistant gloves
  • Safety glasses

Pull sleeves down over gloves and tuck pants inside boots; use duct tape at the top of boots to keep mortar and concrete out.

Work Practices

  • Use ready-mixed concrete instead of mixing on site when possible.
  • Use a dry board or waterproof kneepads to protect knee fabric from becoming soaked when kneeling on fresh concrete.
  • Remove jewelry such as rings and watches because wet cement can collect under them.
