Safer Air in Artisanal Mining

Selected artisanal and small-scale gold-mining cooperatives in Migori County, Kenya

A cooperative-based programme to reduce exposure to silica dust through hazard recognition, miner training and practical dust-control measures.

Programme pathway

From hazardous dust to safer air

Hazardous Dust

Silica-laden dust from drilling, crushing and grinding — invisible, respirable and silicogenic.

Silicosis risk
TB vulnerability
Chronic disease

Safer Working Environment

Trained cooperatives, practical controls in place and a system for ongoing follow-up and verification.

Trained local trainers
Practical dust controls
Follow-up routines

How it works

Step-by-step pathway

01

Hazardous Dust

Drilling, crushing, grinding and dry ore handling generate respirable silica dust. Without controls, miners inhale particles causing silicosis, other respiratory disease and elevated TB risk.

02

Recognition

MHN trains cooperative trainers and miners to identify dust-generating tasks, understand silica-related health risks, and document site characteristics that determine which controls will work.

03

Control Selection

Practical engineering and work-practice controls are selected with cooperatives — using site observations, occupational-hygiene expertise and locally available resources. Dust capture, water mist and process changes are evaluated.

04

Implementation

Controls are demonstrated and installed with cooperative support. Maintenance and supervision routines are established to ensure controls stay effective over time.

05

Safer Working Environment

Participating cooperatives have trained local personnel, documented priority tasks, operational controls and follow-up systems. Claims of exposure reduction made only where supported by appropriate measurement.

Planned activities

What the programme does

  1. 1

    Prepare 6–8 cooperative trainers through a focused 4–6 hour training-of-trainers programme.

  2. 2

    Deliver 90–120 minute practical learning sessions intended to reach more than 100 miners during the first year.

  3. 3

    Document dust-generating tasks, existing control practices and site characteristics relevant to control selection.

  4. 4

    Demonstrate feasible dust-reduction measures and maintenance practices.

  5. 5

    Advance technical development and field evaluation of a low-cost electrostatic and low-flow water-mist dust-control concept, subject to safety and technical review.

  6. 6

    Track training delivery, control adoption, maintenance and implementation barriers.

Expected outputs

What it produces

  • Trainer and miner learning materials

  • Site observation and control-selection tool

  • Documented site-specific recommendations

  • Training and implementation records

  • Technical learning note on feasible dust-control options

  • Recommendations for expansion to additional cooperatives

What success looks like

Participating cooperatives will have trained local personnel, clearer knowledge of silica-dust risks, documented priority tasks, practical control actions and a system for following up implementation. Any claims of exposure reduction will be made only where supported by appropriate measurement and technical interpretation.
