Dust-control prompt

Screen the task for a control combination prompt. Specialist hazards suppress the generic route; COSHH assessment and the control hierarchy still govern.

CONTROL PROMPT

Entered dust task

Method and worked example

Specialist hazards suppress the generic table. Wood/MDF powered sanding → H- or M-class on-tool extraction + APF 20 prompt. Wood/MDF cutting → H/M; APF 20 if enclosed or ≥15 min/day, otherwise assess RPE. Concrete/masonry chasing or dry cutting → H/M + APF 20. Silica drilling/coring → controls and RPE from the applicable HSE sheet. Dusty vacuum cleaning → H/M + APF 20.

Worked example: MDF sanding, 25 min/day, enclosed → H- or M-class on-tool extraction plus APF 20 prompt, extraction-flow and antistatic-hose checks, and face-fit prompt.

Worked example — default entered values

H- or M-class on-tool extraction

APF 20 prompt — for example FFP3 or a half-mask with P3 filter

  • Confirm extraction flow rate for the tool.
  • Use an antistatic wood-dust hose and tight connections.
  • Tight-fitting RPE requires face-fit testing and wearer compatibility.
  • Control combination indicated by the HSE task guidance; check the COSHH assessment and equipment instructions.
Assumptions register

MDF · sanding · 25 min/day trigger time · enclosed · dry · specialist hazard: none

“H or M” is retained because HSE accepts either class for the cited construction wood task.

The tool can accept effective on-tool extraction.

Duration is actual trigger time summed across the day.

APF 20 is a protection-factor requirement, not a product model.

△ Control hierarchy still applies

Extraction class alone does not establish control. Confirm airflow and capture; resolve fit testing and wearer limitations. Asbestos, lead/toxic coatings, biological contamination, combustible/ATEX dust, nanomaterials and unknowns suppress this generic prompt.

CONTROL PROMPT. This screening prompt does not replace the control hierarchy or COSHH assessment. Source control is primary; class, airflow and capture effectiveness must be evidenced. Tight-fitting RPE requires face-fit testing and wearer compatibility.
