Preventing Skin Problems from Working with Portland Cement - Tapa blanda

OSHA 3351-07, Preventing Skin Problems from Working with Portland Cement. Portland cement is a generic term used to describe a variety of building materials valued for their strong adhesive properties when mixed with water. Employees who work with Portland cement are at risk of developing skin problems, ranging from mild and brief to severe and chronic. Wet Portland cement can damage the skin because it is caustic, abrasive, and absorbs moisture. Portland cement also contains trace amounts of hexavalent chromium [Cr(VI)], a toxin harmful to the skin. Dry Portland cement is less hazardous to the skin because it is not as caustic as wet cement. The purpose of this document is to make employers and employees aware of the skin problems associated with exposure to Portland cement; to note the OSHA standards that apply to work with Portland cement; and to provide guidance on how to prevent cement-related skin problems. Measure to protect employees from inhalation and eye hazards associated with exposure to Portland cement are also noted.
