Call for Consensus Body Voting Members: ANS CGA G-13, Storage and Handling of Silane and Silane Mixtures

May 29, 2020

Overview

The Compressed Gas Association (CGA) is working to complete the formation of the consensus body for the proposed American National Standard (ANS) CGA G-13, Storage and Handling of Silane and Silane Mixtures. The purpose of this standard is to prescribe the controls for the installation of silane systems and the recommended methods for storage or transfer of silane or its mixtures from a source of supply to a point of use to provide protection against injury, loss of life, and property damage.

This standard governs the installation of systems and sources that are used to store, transfer, or contain silane or silane mixtures. This standard includes guidance for siting, design of equipment, piping and controls, and the fabrication and installation of silane gas storage and closed-use systems. Additional guidance on operational steps associated with the use of silane and silane mixtures as well as fire protection, gas monitoring, ventilation, and related safeguards are provided.

The requirements of this standard apply to pure silane and silane mixtures with a silane content greater than 1.37%. A concentration of 1.37% has been chosen as it represents the lower flammable limit (LFL) for this material in air under conditions of normal temperature and pressure. Silane containers include tube trailers, International Organization for Standardization (ISO) modules, cylinder packs with manifolded cylinders, and individual cylinders

It is intended that this standard applies to storage and use of silane containers with the exception of small containers with 0.5 scf (14 L) or less of silane content.

This standard is not intended to provide requirements beyond the first point of control within a user’s facility where connections are made to piping systems associated with internal transmission and/or use of this material.

The following subjects are outside the scope of this standard:

  • Equipment downstream of a gas cabinet with the exception of valve manifold boxes (VMBs) when used;
  • Off-site transportation of compressed gases regulated by the U.S. Department of Transportation (DOT), European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR), or other regulatory authorities; and
  • Requirements within the jurisdiction of local, state, provincial/territorial, and national regulatory authorities with laws or regulations that preempt the provisions of this standard. When such is the case, it is recommended that the authority having jurisdiction (AHJ) be guided by this standard in determining requirements.

How to Apply for the Consensus Body

Currently, this ANS consensus body needs voting members from the following interest categories in order to be able to proceed with this publication:

  • Producer: Manufacturer of silane;
  • User: Those who use silane in the manufacturing, research, or development of other products;
  • Distributor/retailer: Silane distributors and retailers;
  • General interest: Industrial insurers, consultants, risk prevention and assessment companies, and those with a general interest in silane;
  • Code Developer: Fire prevention officials, building and fire code developers; and
  • Trade Association: Those representing a trade association with a direct and material interest in silane.

If you have participated on this consensus body in the past, your membership does not carry over and you need to join the consensus body for this revision.

Please note that membership in CGA is not a requirement to join this ANS consensus body.  Currently, there is no fee to join this ANS consensus body.

To ensure that the ANS consensus body interest categories remain in balance, voting privileges are assigned on a first-come, first-served basis to each eligible member who submits an ANS consensus body member application until a balanced consensus body is established. No new voting members will be added after the proposed change cutoff date has passed unless the ANS consensus body becomes unbalanced. If there are more applications for voting privileges than available positions, CGA will maintain a waiting list of potential voting members to be added if the ANS consensus body becomes unbalanced.

If you are interested in participating on this ANS consensus body as a voting member, send an email to Tom Deary, by completing the form below and clicking “Submit.” All required fields are marked with an asterisk (*).
