Types of scaffolding
- Supported scaffolding
- mobile scaffolding
- suspended scaffolding
- metal tubular scaffolding
- Cantilever Scaffolding
4 Common Hazards and How to Reduce Exposure
- Scaffold collapse
- Struck by falling materials
1) Scaffold must be sound, rigid and sufficient to carry its own weight plus four times the
maximum intended load without settling or displacement. It must be erected on solid footing.
2) Unstable objects, such as barrels, boxes, loose bricks or concrete blocks must not be used to support scaffolds or planks.
3) Scaffold must not be erected, moved, dismantled or altered except under the supervision of a competent person.
4) Scaffold must be equipped with guardrails, midrails and toe boards.
5) Scaffold accessories such as braces, brackets, trusses, screw legs or ladders that are damaged or weakened from any cause must be immediately repaired or replaced.
6) Scaffold platforms must be tightly planked with scaffold plank grade material or equivalent.
7) A “competent person” must inspect the scaffolding and, at designated intervals, re-inspect.
8) Rigging on suspension scaffolds must be inspected by a competent person before each shift and after any occurrence that could affect structural integrity to ensure that all connections are tight and that no damage to the rigging has occurred since its last use.
9) Synthetic and natural rope used in suspension scaffolding must be protected from heat-producing sources.
10) Employees must be instructed about the hazards of using diagonal braces as fall protection.
11) Scaffold can be accessed by using ladders and stairwells.
12) Scaffolds must be at least 10 feet from electric power lines at all times.
Here’s a comprehensive list of the do’s and don’ts when using a scaffold, as noted per OSHA.
Do be mindful of coworkers working above and below
Do stay off scaffold during loading or unloading
Do replace guardrails after loading or unloading
- Do use 3-point climbing
- Do exit mobile scaffolds before moving
- Do always wear full protection to avoid accidents
- Do follow OSHA standards for scaffold safety, including personal fall arrest system requirements.
Don’t allow debris or materials to collect on a scaffold
Don’t’ overreach outside the guardrails
Don’t stand on ties, guardrails, or extensions
Don’t overload the scaffold. Proper training includes being informed about the max intended load of the scaffold you’re working on, as well as its load-carrying capacities
Don’t use a scaffold if it appears to be damaged in any way
Don’t climb on any portion of the scaffold frame not intended for climbing
Don’t walk on scaffold planking covered in mud, water, snow, or ice
