Universal Citation: NV Admin Code 459.95412

Current through September 16, 2024

1. The owner or operator of a facility with a process that is subject to C.A.P.P. shall compile written information concerning process safety before conducting a process hazard analysis required pursuant to NAC 459.95414.

2. The information concerning process safety must include, without limitation, information pertaining to:

(a) The hazards of the highly hazardous substances or explosives, including, without limitation:
(1) Toxicity information;

(2) Permissible exposure limits;

(3) Physical data;

(4) Reactivity data;

(5) Corrosivity data;

(6) Thermal and chemical stability data; and

(7) The foreseeable hazardous effects of inadvertent mixing of different materials.

Material safety data sheets that satisfy the requirements of 29 C.F.R. § 1910.1200(g) may be used to comply with this requirement to the extent they contain the information required by this paragraph.

(b) The technology of the process, including, without limitation:
(1) A block flow diagram or simplified process flow diagram;

(2) The process chemistry;

(3) The maximum intended inventory;

(4) The safe upper and lower limits for any applicable process variable, including, without limitation, temperature, pressure, flow and composition; and

(5) An evaluation of the consequences of deviations.

(c) The equipment in the process, including, without limitation:
(1) The materials of construction;

(2) Piping and instrument diagrams;

(3) Electrical classification;

(4) The design of the relief system and the basis for the design;

(5) The design of the ventilation system;

(6) Design codes and standards that were employed;

(7) The material and energy balances for processes that were built after May 26, 1992; and

(8) The safety systems, such as interlocks, detection or suppression systems.

3. The owner or operator shall evaluate processes and equipment for conformance to applicable codes, standards and good engineering practices and document that the processes and equipment comply with recognized and generally accepted good engineering practices.

4. For existing processes and equipment designed and constructed in accordance with codes, standards or practices that are no longer in general use, the owner or operator shall determine and document that the equipment is designed, maintained, inspected, tested and operating in a safe manner.
