3-T SAFETY STANDARD - THROUGH THE TRAP
This is an approved method of tower construction which, if
carried out by a competent person, complies with current safety
legislation.
Construction- basic principles
• Always install the trapdoor over the ladder (if one is fitted).
• Ensure the trapdoor hinges to the outside of a double width
tower (not to the centre).
• Once the platform has been installed, climb, using the
approved method and sit in the trapdoor opening.
Fig 1
• While seated, attach horizontal braces to the frames to form guardrails on both sides of the platform.
• See assembly instructions for specific placement of guardrails.
• 2 braces are normally required each side; although bracing frames can be used on the outside if
desired or specified in the instructions.
• Only when the platform is fully guarded is it safe to stand up on the platform.
Dismantling
• Unlock the brace ends furthest away from the trapdoor.
• Sit through the trapdoor as per Fig.1
• Do not remove braces until sitting in the trapdoor.
• NEVER STAND ON AN UNGUARDED PLATFORM.
