Working at height and ladder safety: the hierarchy, the 1-in-4 rule, three points of contact, stepladders, mobile towers, fragile roofs and harness rescue. Free quiz with instant feedback and a short explanation for every answer. General good practice, not tied to any one country's law; where a rule is UK-specific we say so. It supports, but does not replace, your employer's training and risk assessment.
