You should know that over one-third of the serious injuries to workers in the building trades are caused by falls from one level to another. These accidents usually occur because someone is working or standing on an unsafe surface (a makeshift scaffold) or using a scaffold incorrectly or working on one that hasn’t been put up properly. They may seem safe but they can be very dangerous. Makeshift scaffolds should not be used and are made of such things as:

• concrete blocks
• boxes
• buckets
• piles of scrap material
• poorly supported wooden planks
• machinery

Take the time to build a safe scaffold. We are not in such a hurry that we are willing to sacrifice safety. There are a couple kinds of scaffolds that are acceptable if built right. Some examples of scaffolds and things to remember when erecting them are:

Rolling Scaffold

• They should only be used on a level surface.
• The height should not exceed 4 times the minimum base dimension, unless guyed or equipped with outriggers.
• Decking should be full width and secured against displacement.
• They should have guardrails, midrails and toe boards.
• All casters should be locked except when the scaffold is being moved.
• No one should be on it while it is being moved.

Tubular Metal Scaffold

• Should be tied to and braced against the structure at intervals not to exceed 30 feet horizontally and 26 feet vertically.
• They should have guardrails, midrails and toe boards.
• Screwjacks should be adjusted to plumb and level the scaffold.
• All crossbracing should be installed.
• Mudsills should be used on soft ground.
• Planks should be lapped not less than 12” nor more than 18”.
• Ice or snow should be cleaned off before it is used.
• Safe means of access should be provided – Climbing crossbracing is prohibited.
