Steel Erection Safety

Steel erection involves assembling structural steelwork at height, making it one of the most dangerous construction activities.
Falls from steel, struck-by incidents, and structural collapse are the primary causes of death during steel erection.
The Work at Height Regulations 2005 and CDM 2015 apply to all steel erection work on construction sites.
A steel erection method statement and sequence plan must be approved and briefed before any steel is lifted.
Temporary bracing must be installed immediately to prevent instability during the erection sequence.
All steel connections must be bolted up to the required standard before releasing the crane from the load.
Working platforms, safety nets, or harness systems must be in place before anyone works on steel at height.
Wind speed must be monitored — erection should stop when conditions exceed the agreed safe working limits.
Steel members are heavy and have sharp edges — correct slinging, handling, and PPE are essential throughout.
Only trained, competent steel erectors with valid CSCS or equivalent cards may carry out steel erection work.

Prevent fatal falls	Workers on steel structures at height face extreme fall risk — safety nets, platforms, and harnesses are essential.
Prevent collapse	Incorrect erection sequence or missing temporary bracing causes sudden structural collapse with fatal consequences.
Legal compliance	CDM 2015 requires a detailed method statement and fall protection plan for all steel erection operations.

Don't

Follow the approved erection sequence and method statement for every steel frame.
Install temporary bracing immediately after each section of steel is positioned.
Ensure all bolted connections are secured before releasing the crane from the load.
Use safety nets, working platforms, or harnesses for all work on steel at height.
Check wind speed regularly and stop erection when limits are exceeded.
Inspect all lifting equipment and slings before each lift of steel members.
Wear gloves, hard hat, and eye protection when handling steel with sharp edges.
Maintain exclusion zones below steel erection areas to protect workers from falling objects.
Brief all workers on the erection sequence and emergency procedures before each shift.
Report any misaligned connections, damaged members, or concerns about stability immediately.

DON'T deviate from the approved erection sequence or method statement on site.
DON'T leave steel members unbraced — install temporary bracing immediately after placing.
DON'T release the crane until all connections are bolted to the required standard.
DON'T work on steel at height without fall protection in place as specified.
DON'T continue erection in high winds — stop work and secure all loose steel.
DON'T use damaged slings, shackles, or lifting equipment for steel erection lifts.
DON'T handle steel members without gloves — sharp edges cause serious lacerations.
DON'T walk or work beneath steel being lifted or positioned by the crane.
DON'T carry out steel erection without valid training and a competency card.
DON'T ignore signs of instability such as excessive deflection or misalignment.
