What is the exposure limit value for dust?

The exposure limit value for dust can vary depending on the specific type of dust and the jurisdiction. In general, the exposure limit value for total inhalable dust is typically around 10 mg/m3 for an 8-hour time-weighted average. However, it is important to consult local regulations and guidelines for specific exposure limit values for different types of dust.

The exposure limit value (ELV) for dust varies depending on the specific type of dust and the jurisdiction. Here are some common ELVs for dust:

Total dust (inhalable particles)

- Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL): 15 mg/m³ (total dust)

- National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 10 mg/m³ (total dust)

Respirable dust (particles that can penetrate the lungs)

- OSHA PEL: 5 mg/m³ (respirable dust)

- NIOSH REL: 5 mg/m³ (respirable dust)

Specific types of dust

- Silica dust: OSHA PEL: 50 µg/m³ (respirable quartz), 250 µg/m³ (respirable cristobalite)

- Wood dust: OSHA PEL: 5 mg/m³ (respirable dust), 15 mg/m³ (total dust)

- Cotton dust: OSHA PEL: 20 µg/m³ (respirable dust), 1 mg/m³ (total dust)

Note: These are just a few examples, and the ELVs for dust may vary in different countries and jurisdictions. It is important to consult the relevant occupational health and safety regulations for the specific jurisdiction and industry.
