Question
Which three of these processes commonly produce harmful substances?
- Sanding wood
- Washing overalls
- Tile cutting
- Erecting scaffolding
- Digging a trench
- Curb cutting
Solution
The three processes that commonly produce harmful substances are:
-
Sanding wood - This process generates wood dust, which can be harmful when inhaled and may lead to respiratory problems.
-
Tile cutting - Cutting tiles, especially ceramic or stone, can produce silica dust, which is a carcinogen and can cause lung disease.
-
Curb cutting - This process can release dust and debris, including potentially hazardous materials, especially if the curb contains old asphalt or concrete.
These activities all pose risks related to inhalation of fine particles and dust, making them potentially harmful.
