Good scaffolding design is necessary from the outset. This is to prevent falls, trips, manual handling disorders from occurring, and projectiles from falling and other dangerous situations from occurring. The Work at Height Regulations 2005 require scaffolding to be designed competently so that it is stable and fit for use. The National Access and Scaffolding Confederation has the standards in place for the practice of erecting scaffolding correctly.
Before scaffolding can be erected, one must consider all the functions of it. The will include the site location, the period of time the scaffold will need to be in place, the height and length of the scaffolding, the number of boarded lifts and the maximum working load at any one time. Also, other factors would have to be taken into account, such as the type of access to the scaffold (for example, staircase, ladder), whether there is a requirement for netting and whether a pedestrian walkway is required. The ground conditions and even the weather conditions have to be factored in. There are some scaffolds that require a customised design. These include those involving mobile towers, temporary ramps, access scaffolds with working lifts, marine scaffolds, rubbish chutes and pedestrian foot bridges.
All employees must be trained and understand how to navigate around scaffolding. PPE will need to be worn such as hard hats, gloves (if required), safety shoes, reflective clothing and any other protective equipment. A harness may also be required. Trainee scaffolders should work under a competent supervisor.
Although there are many hazards posed with working with scaffolding, falls from height are one of the greatest hazards. In order to comply with the Work at Height regulations, the employer/self-employed must ensure that the risks are assessed, the risks of working on/near fragile surfaces is managed and that the equipment used is properly inspected and maintained. A visible tag system for use in scaffolding will notify others that the scaffolding has been inspected. There can also be a risk of falling during the erection of the scaffolding; this must be controlled as well. This can be controlled by use of an advanced guard rail system. If this is not used, workers should wear a harness.
