Nev. Admin. Code § 459.95414 - Process hazard analysis
1. The owner or
operator shall perform an initial process hazard analysis on a process that is
subject to C.A.P.P. before introducing highly hazardous substances or
explosives to the process.
2. An
owner or operator may use a process hazard analysis that was previously
completed to comply with
NRS
459.380 to
459.3874,
inclusive, or
29 C.F.R.
§
1910.119(e) to
satisfy the requirement to perform an initial process hazard analysis provided
that the analysis reflects the current process.
3. The owner or operator shall obtain the
approval of the Division concerning the methodology of the process hazard
analysis before conducting the analysis.
4. The owner or operator shall select one or
more of the following methodologies as required by the complexity of the
process:
(a) A "what if" analysis;
(b) A checklist;
(c) A "what if" analysis combined with a
checklist;
(d) A hazard and
operability study;
(e) A failure
mode and effects analysis;
(f) A
fault tree analysis; or
(g) An
appropriate equivalent methodology.
5. When preparing a process hazard analysis,
an owner or operator shall consider:
(a) The
hazards of the process;
(b) Any
previous incident that had a likely potential for catastrophic consequences,
including, without limitation, near misses or accidental releases;
(c) The engineering and administrative
controls that are applicable to the hazards and their interrelationships,
including, without limitation, the appropriate application of detection
methodologies such as process monitoring, control instrumentation with alarms
or detection hardware;
(d) The
consequences of a failure of engineering and administrative controls;
(e) The siting of the facility;
(f) The human factors; and
(g) A qualitative evaluation of a range of
the possible safety and health effects of a failure of controls.
6. If not evaluated as part of the
process hazard analysis pursuant to subsections 1 to 5, inclusive, a separate,
dedicated hazard analysis, utilizing a checklist or other appropriate method,
must be conducted to evaluate:
(a) Human
factors;
(b) Facility siting;
and
(c) External forces.
7. The owner or operator shall
conduct the process hazard analysis with a team with expertise in engineering
and process operations. The team must consist of two or more persons and
include at least:
(a) One member who has
experience and knowledge specific to the process being evaluated; and
(b) One member who is knowledgeable in the
methodology for the specific process hazard analysis being used.
8. The owner or operator shall:
(a) Promptly evaluate the findings and
recommendations of the team formed pursuant to subsection 7;
(b) Determine and document a course of action
based on the evaluation;
(c)
Develop a written schedule of when the actions are to be completed;
(d) Complete the actions as soon as possible
and document each such completion; and
(e) Communicate the actions to operating,
maintenance and other employees whose work assignments are in the process and
who may be affected by the recommendations or actions.
9. At least once every 5 years after the
completion of the initial process hazard analysis, a team that satisfies the
requirements of subsection 7 shall update and revalidate the process hazard
analysis to ensure that the process hazard analysis is consistent with the
current process.
10. A process
hazard analysis must be updated and revalidated using a team meeting the
requirements of subsection 7 and pursuant to the procedures set forth in NAC
459.9549 to 459.955, inclusive.
11.
An owner or operator shall retain a process hazard analysis and an update and
revalidation for each process subject to this section, as well as any
documented resolution of recommendations described in subsection 8, for the
life of the process.
