Multi-Trade Coordination Safety

Multi-trade coordination manages the safety interactions between different trades working in the same area.
Clashes between trades are a leading cause of incidents, particularly on busy fit-out and finishing phases.
Overhead work by one trade creates falling object hazards for trades working below in the same zone.
Electrical isolation by one trade may be compromised if another trade re-energises without checking.
Shared access routes, scaffolds, and welfare facilities require coordination to avoid overcrowding.
Noise, dust, and fume from one trade can affect the health of workers from other trades nearby.
CDM 2015 requires the principal contractor to coordinate activities between all trades on the project.
Short-interval look-ahead programmes and coordination meetings are essential management tools.
Permit systems help manage conflicting activities such as hot works near painters or dusty works near food areas.
Good coordination prevents double-booking of cranes, access equipment, and isolation points.

Prevent clashes	Uncoordinated trades working in the same space create falling objects, struck-by incidents, and exposure to other trades hazards.
Legal duty	CDM 2015 Regulation 13 requires the principal contractor to plan, manage, and coordinate the work of all contractors.
Efficiency	Poor coordination causes rework, delays, and frustration that leads to rushed work and unsafe shortcuts.

Do

Don't

Attend daily coordination meetings and raise any trade interface concerns.
Check who else is working in your area before starting your task.
Establish exclusion zones below overhead work to protect trades at lower levels.
Coordinate isolation and permit requirements with other trades sharing the area.
Communicate your planned activities and hazards to adjacent trade supervisors.
Use the permit system where conflicting activities overlap in the same zone.
Share access equipment, scaffolds, and routes fairly and keep them clear.
Plan noisy or dusty work for times that minimise impact on other trades.
Report coordination failures or near misses to the site management team.
Brief your team on other trades working nearby and their specific hazards.

DON'T start work without checking who else is in the same area.
DON'T carry out overhead work above other trades without exclusion zones.
DON'T re-energise systems without confirming no other trade has a live isolation.
DON'T block shared access routes with your materials or equipment.
DON'T generate excessive dust or fume without warning adjacent trades first.
DON'T ignore coordination meetings; your absence puts other trades at risk.
DON'T assume other trades know about your hazards; communicate directly.
DON'T double-book cranes, hoists, or access equipment without coordination.
DON'T carry out hot works near flammable materials stored by another trade.
DON'T blame other trades for clashes; raise problems constructively at meetings.
