Guide for Compliance with Safety Codes and Standards
Challenge – Codes and standards (published or adopted) may not have ‘caught up to’ ES technologies and their applications
Purpose – facilitate timely review and approval of ESS
technology installations under current CSR Intended uses –
help those who need to document compliance
help those responsible for verifying compliance Frequently asked questions –
Twenty common questions (and detailed answers) Cover what is needed to understand documenting and
verifying compliance under current CSR2
Product and component review and approval
List of standards provided for systems and components and guidance provided for securing approval
Guidance provided for securing approval when no standards are available or approval beyond traditional testing and listing is desired

FMEA Analysis Techniques for System Reliability – Procedure for Failure Mode and Effects Analysis
based on the application and use of IEC 60812 OR NFPA 791
Consider a functional safety analysis to augment the FMEA based on the application and use of IEC 61508, Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems.

Summary of steps and topics to be addressed in securing approval for an installation: Administrative – purpose and scope of CSR and how to apply to a
proposed ESS installation References – referenced documents in the CSR can be part of the CSR, any
other code, standard, or regulation document related to installation Definitions – critical in sorting out how to apply the CSR to an installation ESS equipment and components – how testing and listing to standards (or
not) impacts the degree to which installation related CSR impact the ESS Siting – how location of the ESS is addressed in CSR
Installation Review and Approval
7
Interconnection with other systems – what is covered and what is required, connections to communications, electrical inputs and outputs, other energy related systems
Ventilation, exhaust and thermal management – flow rates, intake and exhaust locations, etc.
Fire protection – fire and smoke detection, fire suppression, containment, smoke removal, containment of effluent fluids, access, egress and signage
Commissioning – validation of proper operation
Listing of CSRs related to the installation of an ESS provided

Purpose – Help AHJs validating ESS installations
recognize issues they need to look out for Resource for permittee who is responsible for
compliance of an ESS
Intended uses – help those who need to document
compliance help those responsible for verifying compliance
