Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the direct supervision of a scaffold competent person.
Scaffold components cannot be mixed if they are from different manufacturers unless they fit together without force. Unless the competent person has approved, scaffold components cannot be used if:
- They are from different manufacturers; or
- Of dissimilar metals.
Each employee who performs work on a scaffold shall be trained by a person qualified to recognize the hazards associated with the type of scaffold used and to understand the procedures to control or minimize those hazards. The training shall include such topics as the nature of any electrical hazards, fall hazards, falling object hazards, the maintenance and disassembly of the fall protection systems, the use of the scaffold, handling of materials, the capacity and the maximum intended load.
Supported scaffold poles, legs, posts, frames, and uprights shall bear on base plates and mud sills (or other adequate firm foundation). The size of the mud sill shall be based on the type of soil the scaffold will be erected upon.
Minimum Mud Sill Size Scaffolds
- 4 levels or less in height - 2" x 10" pad, 18" long
- Scaffolds > 4 levels on Type A Soil - 2" x 10" pad, 18" long
- Scaffolds > 4 levels on Type B Soil - 2" x 18" x 18" pad
- Scaffolds > 4 levels on Type C Soil - 2" x 36" x 36" pad
- Base Plates MUST be nailed to the mud sills on at least 2 opposite corners to prevent slippage.
- Unstable objects, such as bricks, cinder blocks, buckets, scrap lumber, etc., shall not be used to support or level scaffolds.
- Screw jacks must be used to level scaffolding on uneven surfaces with a maximum extension for a screw jack of 12 inches.
- Supported scaffold poles, legs, posts, frames, and uprights shall be plumb (i.e. perfectly vertical) and braced to prevent swaying and displacement.
- Cross-bracing is required on both front and back sides of each scaffold buck or frame.
- To check a scaffold for being plumb, use a level on two opposite uprights.
- To make sure the scaffold is level, use a level on a horizontal support or bearer.
- To ensure the scaffold is "square", use a tape measure and measure the distance between opposite corners. The two measurements should be equal.

a carpenter, was doing framing for a custom-sized space on the second story of
a house. Throughout the day, a number of wood pieces, scraps, and saw dust accumulated
around the saw horses, power tools, cords, and materials piles. Because Sharon
could not see the hazards lying just beneath the saw dust, she tripped and fell
down the stairwell, injuring her neck.
could Sharon’s injury have been avoided? Simply put, the injury could have been
avoided through proper housekeeping practices.
is a key responsibility of every worker on the job site as the orderly arrangement
of work areas is vital to the safety of all workers, regardless of whether they
are involved with machines and tools or with appliances and furniture.
IS HOUSEKEEPING and WHY IS IT IMPORTANT?
refers to maintaining materials, work areas, and walking areas in a clean,
orderly, sanitary, and dry condition. Based on this definition, it’s easy to
see the connection between a clean job site and a reduction in hazards, production
delays, property damage, and even costs.
TIPS TO SAFETY
in Its Place. It
is a lot easier to do your job when your work area is kept neat so take the
extra time to keep your tools and equipment off the floor and stored in the
proper places. Also, trash like scrap building materials, water bottles, and
other debris doesn’t belong on the floor when appropriate receptacles are only
a few steps away.
- Stacking Makes a Difference. Take
time to stack materials neatly and keep in mind that it’s unsafe to stack items
too high. Utilizing moveable pallets and carts to stack materials can limit injuries
during handling while increasing efficiency.
a Quarterback. Keep
your eyes open for changes in the defense or certain other telltale moves of
opposing players. Translation: keep a lookout for danger signals such as loose
flooring, articles out of place, or other unsafe conditions.
are all dependent on each other for safety, so let’s all keep our work areas
tidy; ultimately, this makes the whole job site a safer place to work.
