Working Safely with Concrete and Cement

Concrete isn’t just a mixture of cement and water, it contains some pretty dangerous ingredients.

Alkaline compounds such as lime can be corrosive to the skin. Chromium causes allergic reactions. And then there’s silica, the lung-damaging substance that is so dangerous a tighter standard was implemented in California and across the country within the last 18 months.

The risk of illness or injury depends on the level and length of exposure and the sensitivity of the individual.

What your employees need to know about concrete

Inhalation of cement dust may occur when workers empty bags of dry cement material to make concrete, cut concrete work tiles, and use jackhammers to break up a sidewalk or road during repairs.

This exposure can cause nose and throat irritation. Long-term exposure to concrete dust containing crystalline silica can lead to a disabling lung disease called silicosis.

However, breathing problems are just one concern. If cement dust or wet concrete comes in contact with the skin, burns, rashes, and skin irritations can develop.

Also, should dust from concrete or cement get in the eyes, immediate or delayed reactions may occur, ranging from redness to painful chemical burns.

What your employees need to do

To minimize the risk of contact to the skin and eyes, wear the proper personal protective equipment (PPE). (See sidebar).

To reduce the chance of breathing in cement dust:

  • Wet down the work area to keep dust out of the air and use wet cutting methods rather than dry cut masonry products.
  • Use engineering control methods such as vacuums to pull the dust out of the air.
  • If dust can’t be avoided, wear the appropriate respiratory protection, which must be approved by the National Institute for Occupational Safety and Health (NIOSH). Respirators also must be provided upon request.
  • Mix dry cement in well-ventilated areas.
  • Remember to wash your hands and face before eating, drinking, or using the restroom. And, if wet or dry concrete gets on your skin, wash it off as soon as possible.

What to cover at your safety meeting

Demonstrate and discuss when to use each of the above control methods. For example, the wet method is considered the number one line of defense to minimize the risk of breathing in dust particles. But, isn’t always appropriate.

On roof tops the wet method should not be used because it creates a slip/fall hazard for your workers. Vacuum dust collection systems should be used instead.

In addition, review and demonstrate how PPE should be worn and that your employees know where the washing station and first aid kit are located.


When working with cement, the skin, eyes, lungs, and other internal organs are all at risk. The potential of short-term and long-term injuries is there. But your workers are much less at risk if they are wearing the right clothing and controlling the amount of dust particles that emit into the air. This ensures they’re on hand each day to help you bring your projects to conclusion, minimizing the risk of costly delays.
