The site on which a scaffolding is to be constructed must be level and firm. Loose or soft soil, snow and ice must be removed prior to installation and replaced with gravel or stones. Scaffolding must have secure base plates that are capable of withstanding the weight of the scaffold and the entire load on it.
Choice of Scaffold Before selecting a scaffold, an employer must consider several factors such as site requirements, number of workers, surrounding scenario, public safety and duration of the project. Before installation of scaffolding, the employer must ensure that the correct product has been delivered and that it meets the weight requirements.
A scaffold must have a safety rating of four or more. Such a scaffold can bear a load that is up to four times its rated capacity. The scaffold must not be overloaded beyond a safe limit. All the different components of scaffolding, such as the joints and the fasteners, must have the same capacity.
Design Considerations A qualified engineer or a person who is familiar with scaffolding safety regulations must design and supervise the installation of the scaffolding gyqdlqjj. Every time scaffolding is modified in any manner or is moved, a qualified person must check it before it is used again.
