Extending ladder, rope-operated ladder (or
N
combination ladder as an extending ladder)

When using a combination ladder as an extending ladder,
ensure that your feet do not catch in any nylon belts that
are present.

By preference, slide an extending ladder out against a wall
up to the required height.

Ensure for multi-section ladders that the hooks properly
grip onto or under (rope-operated ladders) the rungs.

Check the locking of the various ladder sections before
climbing the ladder (figure 4).

The hooks are fitted with a locking catch. Always lock this
locking catch and unlock it only for sliding the sections in
and out. The locking catch is to ensure that the ladder
does not slide out by accident.

Make sure that it is only possible to climb the ladder from
the extended side (except for rope-operated ladders).

Make sure that the correct sequence is followed when
sliding out the ladder: unlock the upper section of the
ladder, slide it out to the required height and then lock it
into place. If the ladder has 3 sections, repeat this
procedure with the middle section.

Always slide in the middle section of the ladder first of all
(unlock, slide in, lock) and then the upper section of the
ladder (unlock, slide in, lock). Pay particular attention to
ensuring that the ladder sections are locked and unlocked
at the right time.

When the rope-operated ladder is used, the loose end of
the lifting cord should be secured (when in the in-use
position) to at least two rungs, where possible vertically
below the lifting installation.
Use of the stepladder or ladder

Never load a stepladder or ladder in excess of 150 kg (= a
person climbing the stepladder or ladder including any
"baggage").

When carrying out work, always keep both feet on a
step/rung of the stepladder or ladder and always face the
ladder/stepladder. Never stand, for example, with just one
foot on the stepladder or ladder and the other foot resting
on a window frame. Never reach or lean too far to the side
when working on a stepladder or ladder (max. 1 arm
length). If the centre of gravity is moved from the centre of
the stepladder or ladder, this can become unstable and
can collapse (rule of thumb: keep your navel between the
uprights of the stepladder or ladder). If necessary,
reposition the stepladder or ladder more frequently.

Do not use a stepladder or combination ladder (in the A
position) to access other (higher) levels.

Only use the ladder (single, extending, rope-operated) to
access a higher level with safety devices in place (for
example, ladder safety step to access a roof/securing to
an object).

Never step sideways off a ladder.

Never climb a ladder any higher than the red rung or never
higher than the 4th rung from the top (the maximum safe
standing height, figure 5).

Never climb a stepladder without a supporting bracket
higher than the 3rd step from the top.

Always climb a ladder in the A position on the side on
which the standing position of the rung is horizontal,
therefore, not on the side with arched beams or the
stabiliser (figure 7).

Never stand astride the ladder (figure 8).

For a 3-section combination ladder, the following
applies:
- Never slide a 3-section ladder in the A position out
further than the red rung to the hinge point (figure 3).
- Never climb a 3-section ladder in the A position
further than to the hinge point (figure 6).

Stepladder/ladders may only be used for light work and for
short periods of time.

If there is an unavoidable risk of direct contact with
electricity, do not use this stepladder or ladder!

Do not use a stepladder or ladder outdoors in high winds
(force 6) or other unfavourable weather conditions.

Never leave a stepladder or ladder unsupervised that has
already been set up for use. Think about (playing)
children.

When possible, close windows and doors (not emergency
exits) in the immediate vicinity of the work.

Climb the stepladder or ladder when you have at least one
hand free. When ascending/descending the stepladder or
ladder, hold on properly. This should always be done
while facing the stepladder or ladder.

Do not use the stepladder or ladder as a bridge from which
work is carried out.

Wear sensible footwear to avoid slipping and/or painful
knocks.

Do not stand on a stepladder or ladder for long periods
without taking regular breaks. Tiredness is a risk!

Use a ladder of the correct length. The ladder should
project by at least one metre above the required standing
or step-over height (figure 9).

Any tools that are used while standing on a stepladder or
ladder have to be light and easy to use.

Avoid any work that could cause sideways pressure on the
stepladder/combination ladder, such as drilling into hard
stone. This can cause the stepladder/combination ladder
to tip over.

While working, hold onto the stepladder or ladder with at
least one hand, or take precautions if it is not possible to
hold on.

No more than one person should stand on a stepladder or
ladder at the same time.

Never stand on the supporting bracket of the stepladder.

Never reposition the stepladder or ladder while somebody
is standing on it.

Never use a stepladder back to front or upside down.
Only climb a single-sided stepladder on one side. Never
stand on the rear frame! The side which can be climbed is
recognisable by the horizontal steps. A double-sided
stepladder can be climbed from either side.

Never use a ladder back to front or upside down. The
position of the ladder will be evident from the standing
surfaces of the rungs that should be horizontal.

Some ladders are fitted with a stabiliser which is supplied
separately. Fit this, prior to use, in accordance with the
enclosed instructions.
Additional safety instructions when using
stepladders/ladders

Never wear baggy clothing or jewellery. These could
become caught when ascending or descending the
stepladder or ladder which could lead to a fall.

Frequently check that the feet are not worn. Worn feet may
damage the support surface, or can result in the
stepladder or ladder slipping.
