Two methods are currently recommended by PASMA, which take account of the fall prevention requirements of the Work at Height Regulations (2005), in co-operation with the HSE’s Work at Height Team, which are:

3T (Through The Trap) 

This method entails the operative working partially through the open trap of a trap platform to position guardrails at appropriate distances above the platform before standing on the platform to continue the assembly process. 

Dismantling entails the unlocking of the guardrails at the end furthest away from the trap, then partially climbing through the trap, before completing the removal of the guardrails, and then descending to the next level to continue the dismantling process. 

Advance Guardrail 

This method entails the use of advance guardrail units which are positioned ahead of the platform, so that when the operative gains access to the platform the advance guardrail unit is already in position.  The operative then installs permanent guardrails, and the advance guardrail unit is then repositioned ahead of the next platform, and the assembly process continued. 

Dismantling entails the positioning of the advance guardrail units to allow the operative to remove the permanent guardrails, then descending to the next level and repositioning the advance guardrail unit at that level to allow the process to be repeated, until dismantling is complete.

The only  advance guardrail currently on the market is PlusGardä manufactured by Turner Access at our factory in Glasgow.
