Dust in the Workplace Guidance

Dust is a common hazard in many industries, including construction, manufacturing, woodworking, and mining. Prolonged or excessive exposure to dust can cause serious respiratory illnesses, skin irritation, and other health problems. This guidance provides essential information to help employers and workers identify, manage, and control dust hazards effectively.

What is Workplace Dust?

Workplace dust consists of fine solid particles suspended in the air. Depending on the source, dust can contain harmful substances such as silica, wood particles, metal fumes, or chemicals. Inhalation of these particles over time can lead to long-term health issues.

Main Hazards Associated with Dust

Exposure to workplace dust can result in:

  • Respiratory diseases: Conditions such as asthma, chronic bronchitis, or silicosis.
  • Skin irritation: Dust can cause rashes or dermatitis on contact.
  • Fire and explosion risks: Certain dusts, like wood or flour, are highly combustible.
  • Eye irritation: Dust can cause eye discomfort, redness, or damage.

Safe Working Practices

To minimise the risks associated with dust:

  • Use local exhaust ventilation (LEV) and dust extraction systems.
  • Provide suitable personal protective equipment (PPE), including masks and goggles.
  • Keep work areas clean with regular wet cleaning or vacuuming using HEPA filters.
  • Avoid dry sweeping or using compressed air to remove dust.
  • Monitor air quality regularly and maintain records of exposure levels.

Legal Requirements

Employers have a legal duty under the Health and Safety at Work etc. Act 1974, the Control of Substances Hazardous to Health (COSHH) Regulations, and the Management of Health and Safety at Work Regulations 1999 to protect workers from dust exposure. Risk assessments and control measures must be in place to ensure compliance.

Control Measures and Risk Assessment

Effective dust management requires:

  • Identifying all sources of dust in the workplace.
  • Implementing engineering controls such as ventilation or extraction systems.
  • Providing training to staff on the safe handling of dust-producing materials.
  • Conducting regular health surveillance for employees at risk.
  • Ensuring proper storage and handling of combustible dusts to prevent fires.

Training and Competence

All personnel exposed to dust should receive appropriate training on:

  • Risks of dust exposure.
  • Safe use of extraction and ventilation systems.
  • Correct use of PPE.
  • Emergency procedures in case of dust-related incidents.
