let’s look at some things gone wrong…
AND NOW FOR SOMETHING COMPLETELY DIFFERENT

A blast at the 620-megawatt combined cycle
gas and oil-fired power plant occurred on 7
February 2010 at 11:17.
The initial blast killed five and injured at least
fifty; one of the injured later died in hospital,
bringing the total death toll to six. *
The plant had been under construction and
was scheduled to start supplying energy in
June 2010.
The local fire marshal said the explosion was
the result of an attempted purging of natural
gas from a pipeline as a test, a procedure
known as a blow-down.
On 5 August 2010, the Occupational Safety
and Health Administration (OSHA) announced
that it planned to fine seventeen companies
involved in the construction of the plant a total
of $16.6 million. OSHA said that it had found a
total of 371 safety violations in the construction
of the plant, 225 of which it considered
deliberate. Credits.

27-11-2011: The National Fire Protection
Association's new standard, published a
few weeks ago and publicly introduced
Tuesday, prohibits the use of natural gas
to clean pipes at industrial plants,
commercial developments and other
projects. *
In 2014 the proposal made its way into
new standards

Aftermath, implications on standards
Disasters can trigger
adjustments to existing
standards.
Standards reflect a
‘Best Practice
Recommendation”

WHAT IS A CODE? WHAT IS A STANDARD?
• The earliest building code is thought to have been developed
sometime between 1955 B.C. and 1913 B.C., during the reign of
King Hammurabi of Babylon.
• The code didn’t specify how to build a building - but laid out the
consequences of not building well. If a house fell and killed the
owner or his child, then the builder, or his child, would be slain
in retaliation.
• A code is a model, a set of rules that knowledgeable people
recommend for others to follow. It is not a law, but can be
adopted into law.
• A standard on the other hand tends be a more detailed
elaboration - the nuts and bolts of meeting a code.
A standard is a recommendation.

Example:
CO2 Concentration Test
PASS:
Design
34% in 60s
Over 30% after 20min
50kg/min ext. CO2
Integrity test
42% in 60s
14kg/min ext. CO2
Actual
40% in 60s
1st Sensor <30% at 30min

MURPHY’S LAW - IMPORTANCE OF SERVICE
Installation company certified clean
installation of pipes and fittings with no
excess hemp; all fittings double
checked for tightness; pipes blown out
with compressed air in surges; door
fan test passed the enclosure.
Full discharge FAIL; nozzles blocked,
fittings leaked, 1” pipe blocked solid
Best practise is one full discharge
every five years, minimum after
installation and/or changes

GOING BEYOND STANDARDS AND CODES?
• Fire Protection is a key factor in keeping a power station future proof
and safe!
• Often fire protection measurements are only implemented according
to fulfil time-based service intervals or current legal requirements.
• Ongoing corrosion, new environmental challenges and the
development of new technical capacities would require a more
dynamic approach.
• Should Fire Protection should ‘grow’ with these requirements?
(before codes or standards can catch up…)
