Buying and Hiring Safe Towers
What this domain covers
Buying and Hiring Safe Towers tests whether you can specify and accept a tower that fits the job, not just one that looks tall enough. You need to translate the task into platform height, working height, duty, access, ground and transport requirements, then check the product and paperwork before money changes hands.
Core rules
- Define the working height first. As a guide, working height is platform height plus about 2 m; choose the platform height from the task, not from the tower's total height.
- State the duty and load: number of people, tools and materials. Confirm the manufacturer's load class for the exact configuration.
- Check the standard, marking, declaration of conformity and user instructions; confirm the tower is complete and compatible.
- Match the tower to the ground and environment: firm level base, castor loading, stabilisers or outriggers, wind exposure and overhead hazards.
- Check platform dimensions, access method, trapdoor size and clearance for assembly inside or outside.
- For hire, agree delivery, assembly, inspection, maintenance and return responsibilities; inspect on receipt and record damage or missing parts.
- Do not accept mixed-brand components, modified parts or a tower without instructions.
Worked example
A task requires reaching a ceiling at 6 m. A hire desk offers a tower with a 4 m platform height. Using the 2 m guide, the working height is about 6 m, so the platform height is broadly right. But the ceiling work needs a person, tools and a light fitting. You check the duty rating, platform size, guardrail and toe board set, stabilisers, and whether the tower can be assembled inside with enough clearance. You also confirm the ground is level and the castors are suitable. The tower is acceptable only if those checks pass; height alone is not enough.
Traps that cost marks
Confusing platform height with working height; ordering by total tower height; ignoring stabiliser or outrigger requirements; accepting a tower with no instructions; and assuming a hire company's tag replaces your own pre-use check.
