Falls from height are among the most serious accidents at work, and many happen on short, routine jobs. A quiz before the task or at a toolbox talk keeps the basic rules fresh.
The principles: avoid, prevent, minimise
In Great Britain, the Work at Height Regulations 2005 set a clear order, and the same logic applies almost everywhere:
- avoid work at height where you can, for example by using extendable tools from the ground;
- prevent falls where it cannot be avoided, with an existing safe place of work or equipment such as guardrails, scaffolds or mobile elevating work platforms;
- minimise the distance and consequences of a fall where the risk remains, for example with nets, airbags or fall arrest systems.
Collective measures, which protect everyone, come before personal ones, which protect only the person using them correctly.
Ladders, towers and fragile surfaces
Ladders are fine for short, light work when a risk assessment says so. Typical quiz points: the 1-in-4 angle (one unit out for every four up), three points of contact, never overreaching, the ladder extending about a metre above the landing point, and checking the feet and rungs before use. For mobile access towers: built by competent people following the manufacturer's instructions, brakes on, outriggers fitted where required, guardrails at the top, and never moved with anyone on the platform. Fragile roofs and roof lights deserve their own questions: you cannot tell by looking whether a surface will hold.
Running the quiz
Use a short quiz at a toolbox talk before work at height starts, or at the end of a training session. People answer from their phones, see the right answer after each question, and the discussion fills the gaps. For a record of who completed it and who passed, use Test mode (Formatore plan) with a pass mark.
