Hazardous chemicals; environment; material
Large drivable milling machines (half lane and larger)
Using large drivable milling machines (half lane and larger) on asphalt pavement, concrete, and other silica-containing materials can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs.

Hazardous chemicals; environment; material
Small drivable milling machines (less than half lane)
Using small drivable milling machines (less than half lane) on asphalt pavement, concrete and other silica- containing materials can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs.

Hazardous chemicals; environment; material
Walk-behind milling machines and floor grinders
Using walk-behind milling machines or floor grinders on concrete or other silica-containing materials can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs.

Hazardous chemicals; environment; material
Handheld grinders for tasks other than mortar removal
Using handheld grinders to smooth or cut the surfaces of concrete, masonry or other silica containing materials can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs.

Hazardous chemicals; environment; material
Handheld grinders for mortar removal
Using handheld grinders to remove mortar (tuckpointing or removing mortar/concrete that has leaked from undersides of slab) can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs.

Hazardous chemicals; environment; material
Jackhammers or handheld powered chipping tools
Using a jackhammer or handheld power chipping tools to break or demolish concrete, stone, masonry or other silica-containing materials can generate respirable crystalline silica dust. When inhaled over time, the small particles of silica can irreversibly damage the lungs.

Hazardous chemicals; environment; material
Vehicle-mounted drilling rigs for rock and concrete
Using drilling rigs mounted on trucks, crawlers or other vehicles to drill into rock or concrete can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs.

Hazardous chemicals; environment; material
Dowel drilling rigs for concrete
Using dowel drilling rigs, also known as gang drills, to drill holes in concrete can generate respirable crystalline silica dust. When inhaled, the small particles of silica can irreversibly damage the lungs.

Hazardous chemicals; environment; material
Handheld and stand-mounted drills
Handheld and stand-mounted drills, including impact and rotary hammer drills are used to drill holes in concrete, masonry and other silica-containing materials. This can generate respirable crystalline silica dust. When inhaled over time, the small particles of silica can irreversibly damage the lungs.

Hazardous chemicals; environment; material
Core saws or drills
Using a core saw or drill (including rig-mounted and handheld core drilling) can generate respirable crystalline silica dust. When inhaled over time, the small particles of silica can irreversibly damage the lungs.
