S.T.A. SYSTEM
SAFE TRUSS ACCESS SYSTEM
User Guide
Introduction
STA System is intended to provide safe access for the fi xing of timber bracing to timber roof trusses.
Ensure that STA System is suitable for providing access for the work being carried out (Risk Assessment).
Before use read the whole of this guide, if the system is passed on to another person they should also receive
these instructions.
Ensure you are using the correct PPE equipment for work being carried out.
Note: If in doubt about anything, consult your line manager, safety advisor or Safety Platforms Ltd.
Specifi cation
STA System is a ladder system which complies with EN131 professional, SWL 150kg.
STA System also meets the requirements of BS2037 Class 1, SWL 175kg.
Inspection
Pre-use check: To be carried out by the user each day before use, after an incident (i.e. ladder dropped), this
check should pick up immediate / serious defects.
This should look at welds for signs of cracks and that there are no loose bolts. Check does not need to be record-
ed.
Detailed Visual Inspection
Should be a thorough inspection of all parts of the system. Should be done and recorded at least once every 6
months depending on usage.
Note: A pre-use check is less detailed and less thorough than a detailed visual inspection.
Note: Treat the system with reasonable care to prevent any damage which could lead to risk of injury.
Safe Use Of STA System – Safe method of working
Access to the work position:
Ensure there is a safe method of gaining access to the work position and of positioning the STA System. This
may be by the use of a working platform below the roof trusses, a safe method of forming access ways across the
trusses (boarding) or another method deemed suitable by risk assessment.
Positioning the STA System:
To position the STA System it should be fed between the trusses on an angle then twisted so the spreader spars
then span onto the trusses.
The bar fi xed at the base of the ladder spans between two roof trusses and sits on the bottom chord of the truss.
To prevent it moving along the truss it should be located in the “V” of a node point or against timbers which pre-
vent it from sliding along the truss.
Ensure the brackets protruding from the spreader bars are located to the outside of each of the two trusses. This
prevents sideways movement of the STA system and ensures the spreader bars remain on both trusses.
Extend the upper section of the two part ladder to the correct working level. Ensure the ladder extends suffi cient-
ly so that 3 rungs of the ladder will be above the rung on which you will be standing. This allows three points of
contact to be maintained whilst fi xing the timber braces.
Before climbing the ladder ensure it is correctly positioned, stable and suitable for the work you are about to do.
Work Position
Positioning the STA System between the correct two trusses allows the most productive and safe method of work-
ing, i.e. it should not need to be positioned between every line of trusses.
From one position bracing should be able to be safely fi xed to two trusses to either side of the STA System. Do
not overstretch to reach further trusses!
Removal
Remove the STA System in the reverse order of the installation and store in a safe and secure manner to prevent
damage, trips or theft.
