Why hydrotest is
HAZARDOUS?
1.5 TIMES design pressure
Hydrotest involves
HIGH PRESSURE.
Hydrotest could
INJURE PEOPLE
and
DAMAGE PROVERTY
So be careful.
Always follow
SAFETY STANDARD and
BEST PRACTICES for hydrotest
LEARNING
how to carry out
hydrotest
SAFELY
is very important
Here are the tips...
Only TRAINED and
AUTHORIZED PERSONNEL
can take responsibility for
the test
11
Ensure test condition with
the DESIGN
intents
22
All fill piping, hose and
temporary closures should
have higher STRENGTH
than the test pressure
33
All piping, valves and fittings
tested should of known
SPECIFICATION
44
NEVER USE susceptible to
brittle or stress corrosion
cracking materials
55
All re-used materials have to
be INSPECTED before used.
66
SUPPORT of piping and
equipment exposed to the
hydrotest should have
proper STRENGTH.
77
Pressure-relief device is
required to avoid
OVER PRESSURE.
88
Make sure no AIR trapped in
the tested pipe or
equipment. It is very
DANGEROUS.
99
Only
AUTHORIZED PERSONNELS
are allowed to be
at the test area.
1010
Hydrotest area has to be
restricted with
SAFETY LINE and protected
BARRIER.
1111
Use WARNING SIGNS to
warn people about the
hydrotest.
1212
WEAR appropriate PPE for
the hydrotest.
1313
Use CALIBRATED pressure
gauge for the test. It must
be able to cover 1.5 to 2
times pressure test.
1414
Get SAFETY WORK PERMIT
prior to hydrotest.
1515
COMMUNICATE the test
planning prior to execution.
1616
STOP the work if unsafe or
potential hazardous
condition found during the
test.
1717
Never STAND in the front of
pressure gauge during the
test.
1818
Enough LIGHTING is
available for the hydrotest.
1919
After hydrotest finished,
RELIEF PRESSURE first prior
to draining water.
