Pneumatic and electric tools and compressors can create a noise hazard. Temporary hearing loss can become permanent with chronic exposure and noise can also adversely affect the heart, circulation, blood pressure, intestines, and balance. This temporary condition can spread to the whole hand and cause permanent damage. Electrical tools create the potential hazard of electrical shock from improperly grounded or faulty wiring. Calcium oxide in Portland cement is highly corrosive to the eyes and respiratory tract, and is moderately corrosive to the skin.
Allergic dermatitis can also occur due to chromium contaminants in the cement.
The silica in the cement is also highly toxic by inhalation. Lung problems from inhalation of Portland cement include emphysema, bronchitis, and fibrosis. Acrylic resins are skin irritants and sensitizers. See our data sheet on plastics for more information.
