Putting it all together

Key Points: Some tasks create very high dust levels Repeated exposure to these causes lung disease Important to control each exposure The bigger the exposure, the better the control measures needed First duty to eliminate The control at source RPE is the last line of defence

Silica Tasks: Cutting Eliminate or minimise

Silica Tasks: Cutting Control: Water (or on-tool extraction) Mask APF 20

Silica Tasks: Wall Chasing Eliminate or minimise Design out Use another method

Silica Tasks: Wall Chasing Control On-tool extraction (M or H class) Mask APF 20

Silica Tasks: Wall Chasing Power Assisted RPE for mortar raking?

Silica Tasks: Breaking Indoors Eliminate or minimise: Design out. Bursting, crushing, cutting, sawing or other techniques. Remote controlled demolition. Hydro demolition.

Silica Tasks: Breaking Indoors Control for handheld breaker: On-tool extraction (M or H class unit) Mask APF20 Control for machine breaker Water spray Filtered cab where possible Mask APF 20 where not

Silica Tasks: Breaking Indoors Also consider Mechanical ventilation Powered hood

Silica Tasks: Rotary Drilling Eliminate or minimise: Direct fastening Limiting holes at design

Silica Tasks: Rotary Drilling One-off holes No special controls Multiple holes totalling ’15’ minutes Dust collector Cordless extraction On-tool adaptor to M or H class unit Main activity On-tool extraction with M or H class unit where possible Mask APF 20

Silica Tasks: Sweeping Eliminate or minimise: Control other tasks! Control Remove larger bits Rake M or H extraction with vacuum attachments etc APF 20 mask depending on what else happening

Wood Tasks: Cutting Eliminate or minimise: Order pre-cut Dedicated cutting areas to minimise spread

Wood Tasks: Cutting Control On-tool extraction (M or H class unit) Mask APF10/20 as well for longer cutting periods (15-30 minutes) /more enclosed space

Wood Tasks: Sanding Eliminate or minimise: Use ‘pre-finished’ Control On-tool extraction (M or H class unit) Mask APF10/20 most situations

Low Toxicity: Grinding/Cutting Eliminate or minimise: Fully skim? Control On-tool extraction (L class unit+) No mask needed

The Benefits Industry figures for extraction: Up to +60% increase in life of tools Up to +20% increase in life of consumables Up to +60% quicker application speed No need to clean up dust created: up to 15 kg/h

Construction Dust Partnership

Construction Dust Partnership Agreed Objectives: Focus on all construction dusts Raise Awareness delivery of a campaign ‘brand’, strap lines and messages via targeted activities Promote Controls, especially for higher risk tasks
