Control Measures
Persons erecting scaffolding must be adequately trained. This will normally be verified by production of a Scaffolder Certificate from a recognised training body. Inspections of scaffolding will be carried out only by those trained competent to do so.
L = Likelihood of Occurrence 1. Improbable 2. Remote 1 – 10% 3. Possible 10 – 50% 4. Probable 50 – 90% 5. Almost certain 90%+
Unacceptable risk, plan out or add further controls Acceptable only if no other method viable and with high level controls in place Acceptable with suitable controls Acceptable, no further action required
