A lot can go wrong when working on scaffolding. A lot of workers get hurt—and some get killed—every year in scaffold accidents however working on a scaffold can be straightforward and safe if everyone involved follows procedures.
Here are your top 10 tips for scaffolding safety.
Ensure everyone is properly trained
Safety regulations require that workers be trained in the design and operation of scaffolding. Training covers important safe work practices such as how to safely get on and off the scaffold (using an access ladder, not the scaffold frame — unless it is specially designed to be climbed and both hands are free to grab the rungs). It should also cover comprehensive fall protection training specific to the type of scaffolding, erecting and dismantling procedures for anyone involved in these activities, and a host of other lifesaving details.
Take the time for prep work
Before using scaffolding, make sure the base is sound, level and adjusted; that the legs are plumb and all braces in place; that locking devices and ties are secured; that cross members are level; and that planks, decks and guardrails are installed and secure. Check the location for ground conditions, such as slopes, and stay clear away from hazards such as overhead wires, obstructions and changes in surface elevation.
Know and respect the load capacity
According to the Ontario Ministry of Labour, failure to consider all the loads to which the scaffold may be subjected is one of the top things that go wrong at the design stage. The scaffold must be strong enough and capable of holding the desired weight, otherwise it could collapse. Don’t try to fit more workers on the platform than it can handle; don’t overload it with equipment and materials; and don’t rest anything on the guardrails.
Ensure the scaffold is properly secured
The scaffold must be adequately braced or tied to the building. If it is wrapped in a tarp for protection from the elements, it could blow over if it isn’t secured. “Bracing must be properly secured in place, otherwise scaffold movement may dislodge an end, reducing the stability of the scaffold. There are several different brace retention or locking systems found on scaffolds. These devices must operate freely for ease of assembly and dismantling, and also lock securely to prevent a brace from dislodging. Nails and other miscellaneous odds and ends should not be used in place of proper retention parts supplied by the manufacturer.”
Inspect and maintain
Scaffolding must be routinely inspected by the supervisor and by a competent person — ideally a professional engineer or a person designated in writing by a professional engineer. In the case of a suspended platform, inspect and test all components including welds, stirrups, connecting pins, connecting plates, trusses, beams and working surface. Check that the lumber is of good quality. If any pieces get broken or damaged, replace them right away. Inspect frames, braces and other components for damage, bends and excessive rust or wear. Also check motors, platforms or wire ropes for damage from chemicals or corrosive material.
Good housekeeping
There isn’t much room on a scaffold, so it’s important to store tools and materials in an orderly fashion. Keep the platform free of obstructions. Place debris and waste material in a container or remove it from the platform immediately.
Keep your balance
A scaffold and its platform must be perfectly level (CSA standard says it mustn’t deviate from the vertical by more than 12 millimeters per three meters of height) to minimize the risk of workers losing balance and falling off. Particularly on swing stages, there must be an adequately weighted counterweight. Pay attention when working on a scaffold. Any sudden movements, or reaching too far from the platform, can cause a loss of balance.
Use appropriate PPE
This includes head protection, non-slip protective footwear and fall protection as required, in the form of a safety harness tied off to a solid structure, such as the building
