MODEL: General
SUBJECT: VITON 'O' RINGS AND SEALS (FLUORO-ELASTOMERS) - SAFETY HAZARDS
PURPOSE:
To advise potentially hazardous condition.
DETAIL:
It has been brought to our attention that 'Viton' material used in manufacture of oil seals and 'O' rings, produces a
highly corrosive acid (Hydrofluoric) when subjected to temperatures above 315° C.
The resulting contamination can have extreme consequences on human tissue since it is almost impossible to
remove after contact.
We therefore recommend the following procedure when it is necessary to inspect any equipment that has been
subjected to a high temperature i.e. fire.
a. Visually inspect for any gaskets or seals which have suffered from heat; they will appear black and sticky.
b. If this is affirmed - Do Not Touch
c. Make enquiries to ascertain the material composition. Any Fluoro-elastomer (Viton, Fluorel or Tecmoflon)
should be considered dangerous but natural rubber and nitrile are non-hazardous.
d. If Fluoro-elastomer seals have been used, then the affected area MUST be decontaminated before
undertaking further work.
e. Disposable Heavy Duty Gloves (Neoprene) MUST be worn and the affected area decontaminated by washing
thoroughly with Limewater (Calcium Hydroxide solution).
f. Any cloths, residue and gloves used MUST be safely discarded after use.
Note: Burning of the discarded items is NOT RECOMMENDED, except in an approved incineration process
where the gaseous products are treated by alkaline scrubbing.

IMPORTANT SAFETY NOTICE
Proper service and repair is important to the safe, reliable operation of all motor vehicles. The service
procedures recommended and described in this publication, are effective methods for performing service
operations. Some of these service operations require the use of tools specially designed for the purpose.
The special tools should be used when, and as recommended.
It is important to note that this publication contains various WARNINGS and NOTES which should be
carefully read in order to minimize the risk of personal injury to personnel, or the possibility that improper
service methods will be followed which may damage the vehicle or render it unsafe. It is also important to
understand these WARNINGS and NOTES are not exhaustive. It is not possible to know, evaluate and
advise the service trade of ALL conceivable ways in which service might be carried out, or, of the
possible hazardous consequences of each way. Consequently, no such broad evaluation has been
undertaken. Accordingly, anyone who uses a service procedure, or tool, which is not recommended, must
first satisfy themselves thoroughly that neither their safety, nor vehicle safety, will be jeopardized by the
service method he/she selects.
Two types of heading are used in this manual to attract your attention.
1. WARNING - This symbol is used when an operating procedure, practice, etc., which, if not correctly
followed could result in personal injury or loss of life. Look for this symbol to point out important safety
precautions. It means - ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
2. Note - This is used when an operating procedure, practice, etc., which, if not strictly observed, could result in
damage to or destruction of equipment.
WARNING
Never use parts which are altered, modified, or weakened in operation. This can seriously
jeopardize the integrity of the machine and could result in property damage or serious personal
injury.
