When the shutter is open, gases flow out of the rotary kiln duct opening that
may be harmful to health. This means:
 Danger of poisoning due to harmful gases.
 Danger of burning due to jets of flame at the duct opening.
During operation of the gas sampling system, the cooling water in the cooling
system gets very hot. This means:
 Danger of scalding in the event of contact with the hot cooling water.
 Danger of burning in the event of contact with the cooling water pipes.
The cooling system contains cooling water with anti-freeze. This means:
 Danger of injury to skin and eyes in the event of contact with anti-freeze.
There may be lubricating oil in the pneumatic box, on the pneumatic motor
filter muffler, and inside the pneumatic motor. This means:
 Danger of injury to skin and eyes in the event of contact with lubricating
oil.
The pneumatic system contains compressed air. This means
 Danger of eye injuries if compressed air escapes, e.g. if compressed-air
pipes burst, when opening screw connections or inadvertently opening
compressed-air pipes with no additional connector.
