THE HEALTH and Safety Executive has warned that certain fall arrestors are being used in the wrong situations, putting users at risk.
The HSE's caution comes after research into retractable 'inertia block' arresters, which found that they were commonly used in circumstances that they had not been tested for.
Principal specialist inspector David Thomas said: 'They should only be used in the vertical plane with an overhead anchor unless the manufacturer clearly states otherwise.
'If used in any other way it may be unsafe and could result in an injury or fatality.' He added: 'The European standard does not cover them being tested for use over edges, and in a fall over an edge the lanyard may break, the braking system may be overloaded or the fall might not be arrested in the distance available.'
