What are the hazards of cutting?

Potential injuries from shear or cutting point hazards include amputation, lacerations, contusions, crushing of tissue, and broken bones. Due to the speed of mechanical parts, injury is inevitable when a body part comes in contact with a shear or cutting point.

What PPE is necessary when sawing concrete?

For concrete sawing, the most important PPEs include safety glasses, respirators, and hearing protection. Of course, proper clothing, footwear, and hard hats also are necessary and sensible for most construction sites.

What are the hazards of concrete?

Common Concrete Construction Safety Hazards to Avoid

• Chemical Burns. Wet cement has a high pH due to the addition of calcium oxide.
• Lifting Injuries. When it’s dry, concrete is incredibly heavy.
• Dust Exposure.
• Falls and Falling Objects.
• Heat-Related Illness.

Should you wear a mask while cutting concrete?

So what does all this mean? It means that if you work with materials that contain silica and you work in an area where silica can become airborne – due to concrete cutting, grinding, coring, stoning, cement mixing and sweeping, or sandblasting – you need to wear a respirator.

How should masonry saw be guarded?

(1) Masonry saws shall be guarded with a semicircular enclosure over the blade. (2) A method for retaining blade fragments shall be incorporated in the design of the semicircular enclosure. These requirements address certain safety hazards associated with the use of masonry saws.

What do concrete workers wear?

Waterproof gloves, a long-sleeved shirt, and long pants should be worn. If you must stand in fresh concrete while it is being placed, screeded, or floated, wear rubber boots high enough to prevent concrete from getting into them.

What safety precautions should be followed when working with concrete?

Is a N95 mask good for concrete dust?

A rating of N95 means that a given mask is guaranteed to filter 95% of particles. These 3M N95 masks can protect against concrete dust and wood shop dust as well as airborne pathogens such as H1N1, influenza, allergies, and swine flu.

Is it safe to cut concrete?

The silica compound is not hazardous unless it is exposed in the air. This often occurs when concrete is crushed, ground or cut with a saw. Exposure to airborne crystalline silica can put workers at risk of developing silicosis, a non-curable lung disease caused by accumulation of silica dust in the lungs.
