Safety Notes
ERECTION & DISMANTLING - THE 3T(through the trap) METHOD
Towers should be erected following a safe method of work, there are two approved methods recommended by
‘Prefabricated Access Suppliers & Manufacturers Association’ (PASMA) in co-operation with the Health and Safety
Executive (HSE) & the “working at height regulations 2005”
The method used for erecting and dismantling the UTS 500 NARROW tower is the 3T METHOD (through the trap).
This method ensures the operators erecting the tower position themselves in the trapdoor of the platform to add or
remove horizontal guardrail braces for the level above the platform.
NEVER STAND ON AN UNGUARDED PLATFORM.
Before assembly or erection of this Mobile Access Tower (MAT) please ensure that:
• A risk assessment has been done and all safety equipment is on site.
• The ground conditions will take the working loads of MAT as specied.
• Always check that the MAT is vertical, (Level, slope, uneven ground etc.) if levelling is required make sure you
adjust legs , in line with instructions (use spirit level).
• Beware of (overhead) obstructions – live wires, electrical apparatus or moving parts of machinery or other.
• Wind conditions are within limits as specied. (Refer to page 6)
• Do not use boxes, ladders, or other devices on the platform to gain additional height.
• If in doubt DO NOT ERECT.
• Check that all components are on site and that they are in good working order before use (refer to the
components and quantities shown at each stage). Auxiliary equipment and safety equipment. (ropes, etc)
• All platforms MUST have horizontal guardrails tted.
• The tower should always be accessed from the inside using the rungs of the end frames.
• Never climb up the outside.
• Do not use the guardrail braces as a rung or step.
• It is recommended that 2 persons erect this tower.
• The assembled tower should not be used as a means to enter or exit other structures, e.g. as a stair tower.
• Beware of horizontal forces (e.g., when using power tools on an adjacent structure), which could generate
instability or overturning of the tower.
• Maximum distance between platforms is 2.25m, maximum distance to the rst platform is 3.4m.
• Maximum horizontal force 20kgs.
• Mobile access and working towers are not designed to be sheeted
• The tower height used should be appropriate for the working height, e.g. within 2 meters above the platform

• User training courses cannot be a substitute for instruction manuals but only complement them.
• Only the original UTS components specied in the manual shall be used.
• Mobile access and working towers designed in accordance with ISO 9001 are not anchor points for personal
fall arrest equipment.
• Working is only permitted on a platform with a complete side protection including guardrails and toe boards.
• Mobile access and working towers are not designed to be used as edge protection.
STABILISERS, WALL PROPS & BALLAST
The tower should be stabilised or propped against the building when being erected and used. In conned spaces the
tower may well be trapped within a corridor and require minimal further stabilisation. It would be down to individual
risk assessments to decide what stabilization is appropriate. Should ballast be required, a platform should be
positioned on the lowest rung and the weights should be rmly attached to it and evenly distributed. For advice on
ballast contact your supplier.
LIFTING OF EQUIPMENT
Tools and other equipment should be hauled up by a person on the platform using rope or similar, through the
trapdoor of the platform or within the tower footprint.
Please see footprint guide on page 16.
Safe working loads of platform and tower not to be exceeded.
MOVING THE TOWER AND LEAVING IT UNATTENDED
• To move the tower it will need to be disassembled and moved as component parts.
• Beware of (overhead) obstructions – live wires, hanging apparatus or other objects.
• Recheck that the MAT is vertical or needs readjustment of legs before ascending. (Using spirit level)
• It is recommended that towers should be tied to a solid structure, when left unattended.
TIES
When ties are required, they should be in accordance with table 17 of BS 5973:1990 and table 24 of BS 5975:1982.
Always tie to a solid structure.
The tie frequency should be at 4 meter intervals or less vertically.
FITTING TOE-BOARDS
1 piece folding toe board, fold out over platform making sure location angle rests ts securely on side of platform.
LIFTING OF INDIVIDUAL TOWER COMPONENTS
Raising and lowering components, tools and/or materials by rope should be conducted within the tower base (i.e.
within the area bounded by the stabilisers). Ensure that the safe working load of the supporting decks and the tower
structure is not exceeded.
Check for environmental changes before every use. (i.e.: all weather conditions) Refer to next page for wind effects.

CHECK LIST, INSPECTION CARE AND MAINTENANCE FOR MOBILE
ACCESS TOWERS
• All components should be inspected before use to ensure that they are not damaged or broken,
particularly the welds.
• ANY damage to ANY part particularly tubular members, castors, platform decking MUST be
replaced.
• Adjustable leg threads should be cleaned and lightly oiled.
• All locking claws should be cleaned, and the locking mechanism checked for operation.
• When storing your MAT, please ensure that all components are neatly stored and not left lying
around where they could be stood on or damaged.
• When transporting the MAT always tie the components down so that they do not move around and
get damaged.
• Should the tower be left unattended it should be tied to a suitable structure and on reuse ALWAYS
check that the tower is vertical and safe before ascending correct and complete structure.
• The MAT is not designed to be lifted or suspended as a complete structure.
• Always keep this instruction manual safe.
• Broken, damaged or incorrect components must never be used. The equipment shall be quarantined
and assessed for replacement repair or destruction.
WIND EFFECTS
• Beware of high, gusty, or moderate breeze conditions in exposed areas. It is recommended that in
wind speeds over a Moderate Breeze (see Beaufort Scale below) that work on the tower is stopped
and reassessed. If the wind becomes a Strong Breeze, (see Beaufort Scale below) the tower should
be tied to a rigid structure. If the wind is likely to reach Gale Force (see Beaufort Scale below) or
over, work should be stopped, and the tower should be dismantled.
• Beware of tunnelling effect caused by open ended buildings, uncladded buildings, building corners
and narrow corridors (especially outside between buildings)
