Heavy duty scaffold is required for holding brick or cement blocks while bricklaying. Scaffolding is rated in terms of pounds per square foot (lb/sq*ft). There are three ratings: heavy (75), medium (50) and light (25) duty.
You should only load scaffolding to 1/4 of their rating. You multiply the rating by the surface area of the plank inside the scaffold and divide by four. For example, a bricklayer is using a heavy-duty scaffold that holds a 6X2 foot platform inside the framework. This scaffold should hold no more than 6x2x75/4 = 225 Lb. of bricks at any time.
