Cautions in Working at a High Place
When mounting the transponder, follow the cautions described below because fall from a high place
leads to serious injury or fatal accidents in most cases.
1) Do not engage personnel who are in bad shape due to sickness
or fatigue and who seem to be inappropriate for other reasons in
working in a high place.
2) Before starting work, carefully confirm the safety of foothold, ladder, net, etc. Provide the
openings such as hatch, manhole, etc. with the handrail, fence, and provisional cover to
prevent fall and drop. Do not sit on or step on the handrail and fence.
3) Personnel who start working at a high place of 2 m or more should use the safety belt to
prevent fall. When working at even a high place of less than 2 m from which personnel is
likely to fall, use the safety belt.
4) Stand ready well to the work, and avoid risky action and unnatural work posture. Particularly
the hammer hits the air or the wrench comes off to result in strong reaction, which causes the
working personnel to fall or the materials and tools to drop. Fully careful to use the hammer
and wrench.
5) Working with slippery shoes (e.g., shoes with spikes and shoes to which oil adheres) put on is
particularly dangerous. Check the back of the shoes before starting work.
6) In rainy, snowy, and frozen conditions, watch personnel's steps. Stop the work that is judged
as dangerous due to gale, heavy rain, and heavy snow. Working at a high place without
illumination at night is also very likely to cause working personnel to make a false step. Do
not work in such a condition.
7) When working at a dark place or at night, provide sufficient illumination for the openings such
as foothold, passageway, stairs, ladder, etc. Do not move the lights without permission.
8) Before and after the work, check the number of materials, and tools carefully so as not to
leave them behind. Because the materials and tools left behind are likely to drop, fully
careful to handle them.
9) Do not drop or throw down anything from a high place. If things are thrown down by
necessity, stretch a rope and set up a keep-out sign or set a guard.
10) When raising or lowering materials, tools, etc., use ropes and bags instead of climbing up and
down the ladder with them held by hands. (Carry out three-point support.)
11) Pay attention to where and way the materials, tools, etc. are placed by putting them into the
waist bag, hanging the tool can in which they are put from the foothold, or tying up big
materials with ropes to prevent them from dropping as well as obstructing a passage.
12) When working at a high place, consider that goods may drop down and take measures such
as setting up a danger sign "Men Working Above" or "Danger Overhead" and stretching a
rope. If personnel work directly under goods by necessity, be sure to alert them to the
danger that goods may drop over them.
