One of the most crucial factors in safe scaffolding use is determining the appropriate load capacity. An overloaded platform creates a dangerous situation for workers. The total weight should not exceed the maximum intended load or the rated load capacity, whichever is less. To calculate the maximum intended load, combine the weight of all individuals, tools, equipment and anything else that the platform must accommodate. For example, if the job requires two workers weighing 200 pounds each and 30 pounds of hand tools, the scaffolding's maximum intended load should be at least 430 pounds. To calculate the rated load capacity, you must determine if the scaffolding is a light-duty, medium-duty or heavy-duty version. The intended load for each is 25, 50 and 75 pounds per square foot, respectively.
