Inspection, Maintenance and Adjustment
Rubber and Plastics
Polymer materials when heated, can form compounds which
are dangerous to health and environment and must therefore
never be burned when scrapped. Also take care when
handling machines which have been subjected to fire or
other extreme heat.
If gas cutting or welding is to be carried out near such
materials, the following safety instructions must be followed:
• Protect the material from heat.
• Use protective gloves, protective goggles and an
approved respirator.
Waste Hazardous to the Environment
Painted parts or parts made of plastic or rubber which are
to be scrapped must never be burnt, but must be taken
care of by an approved refuse handling plant.
Batteries, plastic objects and anything else which is
suspected of being dangerous to the environment must be
taken care of in an environmentally safe way.
Check List After Fire
When handling a machine which has been damaged by
fire or been exposed to intense heat, the following
protective measures must under all circumstances be
followed:
Use thick, gloves made of rubber and wear goggles which
are certain to protect your eyes.
Never touch burnt components with your bare hands, as
there is a risk that you may come into contact with melted
polymer materials. First wash thoroughly with plenty of lime
water (a solution or suspension of calcium hydroxide, i.e.
slaked lime in water).
As a precaution, seals (O-rings and other oil seals) should
always be handled as if they were made of floor rubber.
Treat skin, which is suspected of having come into contact
with burnt floor rubber, with Hydrofluoric Acid Burn Jelly or
something similar. Seek medical advice. Symptom may not
appear until several hours afterwards.
Discard gloves, rags etc. which are suspected of having
come into contact with burnt floor rubber.
