The document discusses the health hazards associated with inhaling dust, including risks such as pulmonary fibrosis and lung cancer. It outlines examples of jobs that create dust and offers safety measures to minimize exposure, such as using water to suppress dust and utilizing personal protective equipment. Additionally, it suggests practical techniques to reduce dust generation on job sites.

Dust Safety
Dust is found in many places on a jobsite and can be hazardous to your
health. This hazard varies depending on the type of dust, the amount
inhaled, the size of particulate, and how well your lungs are able to remove
the dust.
1. Pulmonary Fibrosis (hardening of the lungs, making it difficult to breathe).
2. Cancer of the lungs, abdomen, and nose.
1. Effects on the nervous system.
2. Allergic reactions such as hay fever or more serious
reactions such as asthma.
1. Cutting concrete, wood, or other materials.
2. Scoring/cutting tile.
3. Mixing mortar.
4. Pouring dry cement.
5. Grinding.
6. Knocking or bumping into
dusty materials.
7. Loading, unloading, or transporting dusty
materials.

2. 1. Spraying water on the workpiece before cutting, pouring material, etc.
2. Spraying water on the ground before sweeping. If wet-sweeping is not
possible, use a vacuum.
3. Using a dust collector for tools or equipment if available.
1. Prevent accumulation by cleaning the work area
frequently throughout the shift.
2. Wash your hands before eating or drinking and at
the end of your shift.
3. Use personal protective equipment when it is not
possible to prevent dust from getting into the air.
1. Use low-speed rather than high-speed grinders.
2. Order blocks in various sizes to minimize the need for cutting.
3. Use pre-mixed cement or mortar.
4. Shorten the distance that material is dropped
or tossed when pouring or shoveling
dusty materials.
5. Stand opposite to the direction of the
dust cloud.
