What is dust in the workplace?

Dust in the workplace refers to small particles of solid material that are suspended in the air. These particles can come from a variety of sources, such as wood, metal, chemicals, or other materials used in the workplace. Dust can be generated through processes like cutting, grinding, sanding, or handling materials. Inhaling dust can pose health risks to workers, as it can irritate the respiratory system, cause allergies, or lead to more serious health issues such as lung diseases. Employers are responsible for controlling dust exposure in the workplace to protect the health and safety of their employees.

Workplace dust refers to fine particles of solid matter suspended in the air, typically less than 100 micrometers in diameter. It can originate from various sources within the workplace. Examples of dust in the workplace include:

Organic Dust:
- Wood, paper, and cotton fibers from manufacturing or processing operations
- Grain, flour, and feed in agricultural or food processing facilities
- Animal dander, hair, and feathers in animal-related workplaces

Inorganic Dust:
- Concrete, plaster, and drywall dust in construction and renovation activities
- Silica dust from mining, stone cutting, and abrasive blasting
- Metal dust from grinding, welding, and casting operations
- Coal dust in coal-related industries

Other Types of Dust:
- Combustion-generated dust from engines, furnaces, and boilers
- Pharmaceutical dust from tablet manufacturing and compounding
- Chemical dust from industrial processing and chemical handling

Workplace dust can pose respiratory hazards and other health risks to workers. It can cause respiratory irritation, asthma, allergies, and other chronic respiratory conditions. The composition and concentration of dust determine its potential health effects.
