Scaffold sheeting, netting, and debris fans protect the public and workers from falling materials and debris.
Sheeting acts as a wind sail, significantly increasing the load on the scaffold structure and its ties.
The scaffold design must account for the additional wind loading before any sheeting or netting is installed.
Monofilament netting reduces wind loading compared to solid sheeting while still containing falling debris.
Brick guards and toe boards prevent small items falling from working platforms onto people below.
Debris fans (fans boards) are angled platforms that catch falling materials on scaffolds over public areas.
TG20 compliance notes and the scaffold design must specify whether sheeting or netting is permitted.
Unauthorized sheeting added without engineering approval has caused scaffold collapses in the UK.
Regular inspection is required after high winds to check for torn sheeting and displaced netting.
Scaffold sheeting and netting must be properly secured with approved fixings, not cable ties or string.

Prevent scaffold collapse	Sheeting turns the scaffold into a wind sail — without design approval, the additional load can cause total collapse.
Protect the public	Falling debris from scaffolds strikes pedestrians below — netting, fans, and toe boards prevent this.
Legal compliance	CDM 2015 and the Work at Height Regulations require falling object protection on scaffolds over public areas.

Don't

Confirm the scaffold design accounts for wind loading before installing any sheeting or netting
Use monofilament netting where debris containment is needed with lower wind loading impact
Install brick guards and toe boards on all working platforms to prevent small items falling
Secure sheeting and netting with approved fixings as specified by the scaffold designer
Install debris fans over public walkways and entrances below scaffold working platforms
Inspect sheeting, netting, and fixings after high winds and repair any damage promptly
Check the TG20 compliance note to confirm what protection the scaffold is designed to carry
Coordinate with the scaffolding contractor before adding any protection to the scaffold
Maintain clear access behind sheeting for scaffold inspections and fire escape routes
Remove torn or damaged sheeting promptly to prevent it flapping and increasing wind loads

DON'T add sheeting or solid protection to a scaffold without confirming the design allows it
DON'T use solid sheeting where monofilament netting would provide adequate debris protection
DON'T secure sheeting with cable ties, string, or unapproved fixings that can fail
DON'T ignore torn or displaced sheeting after storms — it increases wind load unpredictably
DON'T remove brick guards or toe boards from working platforms for convenience
DON'T leave gaps in debris netting where materials could fall through onto people below
DON'T block scaffold access or fire escape routes with sheeting or netting fixings
DON'T allow sheeting to accumulate water that adds significant unplanned weight to the scaffold
DON'T assume netting alone protects the public — debris fans are needed over high-risk areas
DON'T install protection without the scaffolding contractor's knowledge and approval
