To avoid ladder accidents, employees have to set up ladders correctly. Be sure to teach them these 10 ladder setup rules.
- Place the ladder on a firm, level surface, and check to
make sure the ladder is stable. Use wide boards under the ladder to
give stability if the ground is soft.
- Never set a ladder on top of a drum, stack of pallets, or
other object to gain more height. Use a taller ladder instead. If you
set up a ladder on such an unstable base, you're just asking for an
accident.
- Never set up a ladder in front of a door unless the door
is locked or blocked—or you've got someone standing on the other side
to keep people from opening the door.
- Never lean a ladder against a surface that isn't strong
enough to support your weight, such as a window or an object that might
move under your weight.
- Never fasten two ladders together for additional height.
Instead, use a taller ladder or an extension ladder designed for
two-ladder coupling.
- Make sure the spreaders on stepladders are fully extended
and locked in place and that locking devices on extension ladders are
secured.
- Remember the 4-to-1 rule: Place the base of the ladder 1
foot from the wall for every 4 feet between the base and the support
point. For example, if it is 8 feet from the base of a ladder to its
support point, the base of the ladder should be 2 feet away from the
building.
- Extend extension ladders at least 3 feet above a support point such as the edge of a roof.
- Make sure that the upper section of an extension ladder
overlaps and rests on the bottom section. The overlap should always be
on the climbing side of the ladder. For ladders of 36 feet or more, the
overlap should be least 3 feet.
- Secure ladders at the top and bottom.
7 Simple Rules for Preventing Falls
- Select the right ladder (height and type) for the job.
- Inspect ladders carefully before each use.
- Follow ladder safety rules and regulations.
- Use common sense—only one person on a ladder at a time.
- Hold on while your climb and while you work
- Don't overreach; get down and move the ladder.
- Report safety problems with ladders right away.
Better Design Could Reduce Stepladder Injuries
Researchers from the Human Factors and Ergonomics Society say
that not only improved user behavior but also improved ladder design
could help decrease the number of stepladder accidents.
Daniel Tichon, Lowell Baker, and Irving Ojalvo explain that
compared with a flat surface, stepladders present a smaller and less
rigid surface on which to stand and balance.
They suggest manufacturers make stepladders more rigid to
provide a stable work platform and offset human balance problems. Front
and rear rails could be made of closed tubular sections and
cross-shaped spreader bars.
