Risks
By loosing the grip a spring and flying parts may cause injury.
Even small springs and retaining rings are dangerous as they
could injure the eyes.
The parking brake chamber springs are under high compres-
sion and may cause very serious injury.
Also gas springs and gas shock absorbers may be under high
load and are dangerous in the same way as “normal” springs.
Also scrapped gas springs and gas shock absorbers may be
dangerous to handle.
Protective measures
Small springs, retaining rings
Retaining ring pliers must be of suitable type and size and in
good condition. Remember that even small springs may be
dangerous.
Use protective goggles.
Heavy springs
Always use recommended tools and safety devices. Follow
the instructions in the work descriptions.
Prevent people with insufficient knowledge and experience
from handling parking brake chambers.
To protect people that handle scrapped gas springs and gas
shock absorbers from injury, special instructions apply in
certain cases for e.g. drilling a hole in the gas cylinder before
discarding scrapped parts.
