Concrete is one of the most commonly used building materials in the world. Despite how common it is, there are still several hazards threatening those working with or around ceramics and concrete. Dry concrete can cause irritation to the eyes, throat, nose, and lungs. Long term exposure to silica (the main component in dry concrete) is linked with developing lung cancer and silicosis (a lung disease.) Employees working on or around concrete should always know which Personal Protective Equipment (PPE) to wear, the proper tools to use, and the proper emergency procedures to follow in case of an incident.
