What?

Why?

Manual handling injuriesHeavy multi-layer board systems cause back, shoulder, and hand injuries without mechanical aids and team lifts.
Dust and fibre exposureCutting board and mineral wool releases harmful dust and fibres requiring RPE and extraction controls.
Quality performanceAny gap in the acoustic envelope destroys the partition's sound insulation — careful sealing is essential.
Do Don't
  • Use board lifters or team lifts when installing plasterboard sheets above waist height
  • Wear RPE when cutting plasterboard and mineral wool insulation to control dust and fibres
  • Seal all perimeter joints, service penetrations, and head-of-wall details with acoustic mastic
  • Follow the specified installation sequence for the acoustic partition system being used
  • Use stepladders or podium steps safely for work at the head of wall and ceiling junction
  • Check the COSHH assessment for acoustic sealants and mastics before application
  • Ensure ventilation is adequate when using solvent-based acoustic sealants in enclosed rooms
  • Fire stop all penetrations through fire-rated acoustic partitions using approved methods
  • Inspect delivered boards for damage and reject any sheets with broken edges or cores
  • Wear hearing protection when using power screw guns and board cutting equipment
  • DON'T manually lift heavy acoustic boards alone — use team lifts or mechanical aids
  • DON'T cut plasterboard or mineral wool without RPE to protect against dust and fibres
  • DON'T leave gaps in the acoustic seal — even small holes significantly reduce performance
  • DON'T use standard plasterboard where the specification requires acoustic-grade boards
  • DON'T skip fire stopping on penetrations through fire-rated acoustic partition systems
  • DON'T apply solvent-based sealants in enclosed rooms without adequate ventilation running
  • DON'T stack heavy board packs on floors without checking the floor's load-bearing capacity
  • DON'T install boards out of the specified sequence — the acoustic performance depends on it
  • DON'T use damaged boards with broken edges that will compromise the sealed partition system
  • DON'T ignore back or shoulder discomfort from repetitive overhead boarding work
