- The Through the Trap (3T) method requires the operative to sit in the trap of the deck to put on the guiderails.
- The Advanced Guard Rail (AGR) method places the guiderails in advance of the working platform, where the operative can ascend the tower and straight onto the working platform or deck with the guiderails already in place.
Both methods are compliant of best practice, but some organisations sometimes show a preference to one method over the other.
