20 Throwback Thursday Memories of Working with Cement
Introduction:
Cement can have detrimental health effects on the human body, particularly through skin contact. Direct contact with wet cement can lead to burns and dermatitis. Cement burns can result in severe skin ulcers, requiring months to heal and potentially necessitating skin grafting. Dermatitis manifests as itchy, sore, red, scaly, and cracked skin. Additionally, eye contact with cement powder or wet cement can cause irritation and inflammation. Furthermore, inhalation of cement dust can irritate the nose and throat, resulting in breathing difficulties. There is also a potential long-term risk of developing chronic chest trouble from breathing in cement dust. Therefore, precautions such as wearing protective clothing, practicing proper hygiene, and handling dry material in well-ventilated areas are essential to minimize exposure.

The Health Effects of Cement
Cement can have detrimental effects on health, primarily through skin contact and inhalation of dust. It is important to take precautions to minimize these risks.
Skin Contact
When in contact with wet cement, both burns and dermatitis can occur. Cement burns are a serious concern and can result in severe skin ulcers that may take months to heal. Dermatitis is another common issue, which causes itchy, sore, red, scaly, and cracked skin. Two types of dermatitis can occur: irritant dermatitis, caused by the corrosiveness and abrasiveness of cement, and allergic dermatitis, caused by sensitization to certain substances in cement and its raw materials.
Eye Contact
Contact with cement powder or wet cement can cause irritation and inflammation of the eyes.
Inhalation of Dust
Handling cement can generate high levels of dust, leading to short-term irritation of the nose and throat and difficulty breathing. The long-term effects of inhaling cement dust are uncertain, but it may lead to chronic chest problems. Abrading hardened concrete can produce inhalable dust containing high levels of silica, which increases the risk of developing chest complaints.
To minimize dust exposure, it’s important to handle cement in a way that reduces dust production, such as opening bags carefully and working in well-ventilated areas.
Controlling Exposure
To protect yourself from the harmful effects of cement, it is essential to wear appropriate clothing and maintain good hygiene practices.
Personal Protection
- Wear gloves.
- Wear overalls with long sleeves and full-length trousers.
- Use waterproof boots.
Hygiene
Personal hygiene is crucial in reducing exposure to cement. Remember to wash your hands and face thoroughly after completing a job and before eating, drinking, or smoking. Additionally, wash your hands before using the toilet.
First Aid
If your skin comes into contact with cement, wash it with cold running water as soon as possible. Pay extra attention to any wounds and cover them with suitable dressings. In the case of eye contamination, rinse your eyes with cold tap water for at least 10 minutes before seeking medical attention.
