They must be inspected regularly to ensure that they are in safe condition. So when should you inspect a ladder and by whom? – By the user each time before they are used. – By someone carrying out a formal inspection every 3 to 6 months (records should be kept of these formal inspections). Browns Ladders & Ceilings said: “We realise that health and safety can be difficult to keep on top of. Not to worry – we offer on-site ladder inspections, carried out in 3, 4 or 6 month intervals. Our inspections cover access equipment within the factory site – from general ladders and steps to machine stairways, tower scaffold and work platforms.
