6.5 Safe procedures of work should also be produced using the ‘Safe Procedure Working Form’, as appropriate. 7. HIERARCHY OF CONTROL 7.1 Under Regulation 6 of the Work at Height Regulations, there is hierarchy of control for determining how to work at height safely. The hierarchy has to be followed systematically and only when one level is not reasonably practicable may the next level be considered. The hierarchy has three basic steps to consider, in order these are AVOID, PREVENT, MINIMISE. 7.2 It is the responsibility of the Duty holder to: Avoid work at height where they can. Use work equipment or other measures to prevent falls where they cannot avoid working at height. Where they cannot eliminate the risk of a fall, use work equipment or other measures to minimise the distance and consequences should one occur. 7.3 It is not always necessary to implement all parts of the hierarchy, e.g. in the case of a fully boarded and guarded scaffold, workers would not be expected to wear personal fall arrest equipment in addition. 7.4 Duty-holders must ensure All work at height is properly planned and organised. All work at height takes account of weather conditions that could endanger health and safety. Those involved in work at height are trained and competent. The place where work at height is done is safe. Equipment for work at height is appropriately inspected. The risks form fragile surfaces are properly controlled. The risks from falling objects are properly controlled.
