Noise in Material Recovery Facilities (MRFs)

The problem

Exposure to noise at work can cause irreversible hearing damage. It is one of the commonest health problems and can be difficult to detect as the effects build up gradually over time.

Most Material Recycling Facilities (MRFs) have processes which emit high noise levels exceeding the 80dB(A) and 85dB(A) levels at which employers are required to take action under the Control of Noise at Work Regulations 2005.

Managing the risk - hierarchy of control measures

Protection is best achieved by controlling noise at source. Follow this sequence to reduce exposure - wearing hearing protection is the last resort:

Control of Noise in MRFs

The table below identifies

Task/Equipment Potential daily exposure Reasonably practicable controls
Glass Tip/Move Telehandler/tipper >UEAV Use a vehicle with a “quiet cab” and keep doors shut.  
Shredders and Granulators >UEAV
(manually fed machines)
  • Load by vehicle.
  • Site machine/s outside or in own room with finger curtain doors.
  • Use resilient mountings to prevent noise transmission via floor/structure.
Picking Lines >UEAV
  • Provide a well constructed noise refuge.
  • Fit open sort chutes with  lining/baffles
  • Provide finger curtains at openings to refuge
  • Reduce drop heights to conveyor.
  • Ensure machinery is well maintained.
Magnetic/Air Separators and Balers <EAV (because not manned - but high source of noise)
  • Site away from work stations and noise refuge
  • Set/configure air flow and overband magnet to prevent turbulence and reduce drop gaps.
Floor Tipping/Sorting >UEAV
  • Mix recycled material (co mingle)
  • Use a vehicle with a “quiet cab” and keep doors shut.
Trommels and Screens. >UEAV
  • Locate away from workers.
  • Load by vehicle with “quiet cab” and doors kept shut.
  • Use resilient  mounts.
