Effective safety communication across the supply chain ensures consistent standards from client to operative.
Construction projects typically involve multiple tiers of subcontractors, each with their own workforce and culture.
Key safety information must flow down to every tier — method statements, risk assessments, and site rules.
Language barriers in a multilingual workforce require translated materials and visual communication aids.
Regular safety meetings, toolbox talks, and briefings maintain communication across different trade teams.
Safety alerts and lessons learned from incidents must be shared promptly across all supply chain partners.
CDM 2015 places duties on principal contractors to coordinate safety communication between all parties.
Digital communication tools such as apps, noticeboards, and QR codes improve information access on site.
Poor communication between trades working in the same area is a common root cause of incidents.
Feedback from operatives to management is equally important — a two-way communication culture saves lives.

Prevent incidents	Most multi-trade incidents result from poor communication — clear, consistent messaging prevents conflicts and injuries.
Legal duty	CDM 2015 requires principal contractors to ensure effective safety communication to all workers on site.
Inclusive safety	Language barriers and literacy challenges mean safety messages must use multiple formats to reach everyone.

Don't

Share site rules, risk assessments, and method statements with every subcontractor tier
Use translated materials and visual aids for non-English-speaking workers on site
Hold regular coordination meetings where different trades discuss overlapping activities
Distribute safety alerts and lessons learned to all supply chain partners promptly
Use noticeboards, digital screens, and apps to display current safety information on site
Ensure every operative receives a site-specific induction covering key safety messages
Encourage operatives to report hazards and provide feedback through accessible channels
Brief subcontractors on emergency procedures and muster points at every site induction
Verify that safety information reaches the operative level, not just subcontractor managers
Record safety communications and maintain evidence of distribution for audit purposes

DON'T assume subcontractor managers pass safety information to their operatives automatically
DON'T issue safety documents in English only when non-English speakers are on site
DON'T rely solely on written documents — use verbal briefings and visual aids too
DON'T delay sharing safety alerts or incident lessons with the wider supply chain
DON'T hold safety meetings without representation from all active trades on site
DON'T ignore feedback from operatives — their observations identify real hazards daily
DON'T treat the site induction as the only opportunity to communicate safety information
DON'T allow trades to start work in overlapping areas without a coordination briefing
DON'T use technical jargon in safety briefings aimed at operatives without H&S training
DON'T file safety communications without confirming they have been received and understood
