Current Text: (multiple locations) ANSI/ASME B31.3 (found in Subsections: ASME Publications; Piping Systems; Piping Systems; Joints; System Design; * Low-Temperature Service; ; ; ; ; Welding (A); Brazing (A); Testing; A ; I ASME Publications) Proposed Text : ANSI/ASME B31.3 ASME standards no longer use the ANSI/ASME designation. Some standards within NFPA 55 have been changed to the ASME designation (e.g., ASME B31.12). This change is requested for consistency.

[1: ] ? When a conflict between a general requirement and a specific requirement occurs, the specific requirement shall apply. [1: ] There are over 70 referenced documents and publications utilized in NFPA 55 as found in Chapter 2 and the potential exists for code users to encounter conflicts. Language is found within NFPA 1 Fire Code and NFPA 5000 Building Construction and Safety Code regarding the approach to be used to resolve conflicts should conflicts be encountered. Similar requirements are found in administrative sections of the International Fire Code (2012 Edition) in Section for Conflicts with reference documents, and in Section regarding conflicts between general versus specific requirements. Establishing a section in NFPA 55 to resolve conflicts will avoid problems in establishing the hierarchy with the use of reference codes and standards.

The distances specified are those required to reduce the radiant heat flux level to 500 Btu/hr ft2 (1577 W/m2) at the property line or the distance to a point in the unignited hydrogen jet where the hydrogen content is reduced to a 4 percent mole fraction (volume fraction) of hydrogen, whichever is greater. In all cases the distance required to achieve a 4 percent mole fraction was the greater distance and used to establish the requirements. 3.3.XX Exposures Group 2. The distances specified are those required to reduce the radiant heat flux level to 1500 Btu/hr ft2 (4732W/m2) for persons exposed a maximum of 3 minutes. 3.3.XX Exposures Group 3. The distances specified are those required to reduce the radiant heat flux level to 6340 Btu/hr ft2 (20,000 W/m2) or the visible flame length for combustible materials, or a radiant heat flux level of 8000 Btu/hr ft2 (25,237 W/m2) or the visible flame length for noncombustible equipment. In both cases the visible flame length was used to establish the requirements. The exposures in chapters 10 &11 simply mention group 1, 2, 3 exposures and don't indicate what they mean or what the concern is. The document either needs to add them as definitions in chapter 3 or add text as was done in the oxygen chapter. Without this the reader has no way of knowing what importance or concern is for those exposure levels. Submitter Full Name: Phillip Mariscal Organization: Compressed Gas Association Submittal Date: Wed Jun 26 10:57:57 EDT 2013 Resolution: The Technical Committee does not believe that chapter specific definitions belong in Chapter 3. This material is adequately covered in the individual chapters and the existing annex material.

Shutoff valves installed between pressure relief devices and containers shall be in accordance with Location. Shutoff valves shall not be installed between pressure relief devices and containers unless the valves or their use meet the requirements of or * Security. Shutoff valves shall be locked in the open position, and their use shall be limited to service-related work performed by the supplier under the requirements of the ASME Boiler and Pressure Vessel Code Multiple Pressure Relief Devices. Shutoff valves controlling multiple pressure relief devices on a container shall be installed so that either the type of valve installed or the arrangement provides the full required flow through the minimum number of required relief devices at all times. A When multiple valves or pressure relief devices are connected to a vent stack or common header, the potential exists for one valve to discharge into the header or stack while personnel are performing maintenance on another valve or pressure relief device. One solution is to install valves on the inlet and outlet of pressure relief devices for maintenance. Closing a full area stop valve on the outlet of a pressure relief device that is being replaced will prevent the backflow of gas from another device that is connected to the same stack or header. Such full area stop valves shall be locked open and shall be provided with manual vent valves for maintaining pressure during maintenance operations in accordance with the ASME Boiler and Pressure Vessel Code. If the full area stop valve is closed, an operator shall be present at all times in order to maintain the vessel pressure within acceptable limits and shall again lock or seal the full area stop valve in the open position before leaving the station (ASME Boiler and Pressure Vessel Code Appendix M-5).

39 Page 39 of 190 Public Input No. 115-NFPA [ New Section after ] Cleaning and purging of end use equipment shall be conducted according to documented procedures in accordance with the requirements of for piping systems. Additional Proposed Changes File Name docx Description Approved Cover Sheet TIA (new section ) requires documented procedures for cleaning and purging of piping systems covered under NFPA 55. However, cleaning and purging of end use equipment also presents serious exposures to personnel injury and property damage. These exposures are currently not addressed by NFPA 55. Cleaning and purging requirements for end use equipment should be included in NFPA 55. The procedural safeguards for cleaning and purging of end use equipment are effectively the same as the TIA requires for piping systems.

(b) When there is a change in service. (c)* When there are alterations or repair of the system involving the replacement of parts or addition to the piping system and prior to returning the system to service. (d)* Where specified by the design standards or written procedures Cleaning and purging of the internal surfaces of piping systems shall be conducted by qualified individuals trained in cleaning and purging operations and procedures, including the recognition of potential hazards associated with cleaning and purging * A written cleaning or purging procedure shall be provided to establish the requirements for the cleaning and purging operations to be conducted * An independent or third-party review of the written procedure shall be conducted after the procedure has been written and shall: (1) evaluate hazards, errors, and malfunctions related to each step in the procedure (2) review the measures prescribed in the procedure for applicability (3) make recommendations for additional hazard mitigation measures if deemed to be necessary The completed written procedure shall be: (1) maintained on site by the facility owner/operator (2) provided to operating personnel engaged in cleaning or purging operations (3) made available to the AHJ upon request Where generic cleaning or purging procedures have been established, a job-specific operating procedure shall not be required Generic procedures shall be reviewed when originally published or when the procedure or operation is changed Written procedures to manage a change in process materials, technology, equipment, procedures, and facilities shall be established by the facility owner/operator The management-of-change procedures shall ensure that the following topics are addressed prior to any change in the configuration or design of the piping system: (1) The technical basis for the proposed change. (2) The safety and health implications. (3) Whether the change is permanent or temporary. (4) Whether modifications to the cleaning and purging procedures are required as a result of the changes identified.
