4590 Micro Reactors
User’s Responsibility
All Parr Reactors and pressure vessels are designed and manufactured with great care to assure safe operation
when used within their prescribed temperature and pressure limits. But . . . the basic responsibility for safety
when using this equipment rests entirely with the user; who must:
1.
Select a reactor or pressure vessel
which has the
capability, pressure rating, corrosion resistance
and design features that are suitable for its in-
tended use. Parr engineers will be glad to dis-
cuss available equipment and material options
with prospective users, but the final responsi-
bility for selecting a reactor or pressure vessel
that will perform to the user’s satisfaction in any
particular reaction or test must rest with the user
– not with Parr.
In exercising the responsibility for the selection
of pressure equipment, the prospective user
is often faced with a choice between over- or
under-designed equipment. The hazards intro-
duced by under-designed pressure vessels are
readily apparent, but the penalties that must
be paid for over-designed apparatus are often
overlooked.
Recognizing these criteria, Parr reactors and
pressure vessels are offered in several different
styles, each designed for convenient use in daily
operation within certain temperature and pres-
sure limits, using gaskets, closures and other
elements carefully selected for safe operation
within the limits specified for that design. But in
order to preserve the validity of these designs,
all temperature and pressure limits must be
observed, and no attempt should be made to
increase these limits by making alterations or by
substituting components which are not recom-
mended by Parr Instrument Company.
2.
Install and operate
the equipment within a
suitable barricade, if required, with appropriate
safety accessories and in full compliance with
local safety codes and rules.
All standard Parr pressure vessels are provided
with either a suitable relief device or a means
to attach one (typically in the form of a plugged
opening). When a pressure vessel is delivered
without a pressure venting device, it is the cus-
tomer’s responsibility to provide pressure relief
in order to protect the operator and the equip-
ment from destructive high pressures. If you
need more information or need help in selecting
a proper relief device, please contact Parr Instru-
ment Company.
3. E
stablish training procedures
to ensure that any
person handling the equipment knows how to
use it properly.
4.
Maintain the equipment
in good condition and
establish procedures for periodic testing to be
sure the vessel remains structurally sound.
