Cement and cement-based products can harm the skin in a number of ways. Wet cement is highly alkaline in nature. A serious burn or ulcer can rapidly develop if it is trapped against the skin. In extreme cases, these burns may need a skin graft or cause a limb to be amputated. Cement can also cause chemical burns to the eyes.
prehensive hazard assessment should identify hazards in both cat-egories. Examples of physical hazards include moving objects, fluctuating temperatures, high intensity lighting, rolling or pinching objects, electrical connections and sharp edges. Examples of health hazards include overexposure to harmful dusts, chemicals or radiation.
Cement kilns, with their high flame temperatures, are sometimes used to burn waste oils, solvents, and other organic wastes. These practices can result in the release of toxic metals and organics. Cement plants are not normally designed to burn wastes but if such burning is contemplated, the technical and environmental acceptability need to be
