NFPA 921 sets the bar for scientific-based investigation and analysis of fire and explosion incidents. Referenced in the field, training, and court, it is the foremost guide for rendering accurate opinions as to incident origin, cause, responsibility and prevention and is intended for use by public sector employees responsible for fire investigation and private sector professionals who conduct investigations for insurance companies or litigation purposes. All aspects of fire and explosion investigation are covered from basic methodology to collecting evidence to failure analysis.

This standard shall establish a common set of criteria for all hazards disaster/emergency management and business continuity programs, hereinafter referred to as “the program.” A.1.1 The Emergency Management and Business Continuity community comprises many different entities, including the government at distinct levels (e.g., federal, state/provincial, territorial, tribal, indigenous, and local levels); commercial business and industry; not-for-profit and nongovernmental organizations; and individual citizens.

The standard identifies and establish levels of functional capability for conducting operations at technical search and rescue incidents while minimizing threats to rescuers. This standard was developed to define levels of preparation and operational capability that should be achieved by any AHJ that has responsibility for technical rescue operations. These defined levels provide an outline of a system used to manage an incident efficiently and effectively to maximize personnel safety and bring about the successful rescue of victims and eventual termination of the event.

The document provides interim guidance for electric and hybrid-electric vehicles and identifies appropriate post-crash safety measures for vehicle owners and the general public, emergency responders, and for towing/recovery operators and vehicle storage facilities.

The document presents the procedures to be followed for the classification of lithium metal and lithium ion cells and batteries (see UN Nos. 3090, 3091, 3480 and 3481, and the applicable special provisions of Chapter 3.3 of the Model Regulations). 38.3.2 Scope 38.3.2.1 All cell types shall be subjected to tests T.1 to T.6 and T.8. All non-rechargeable battery types, including those composed of previously tested cells, shall be subjected to tests T.1 to T.5. All rechargeable battery types, including those composed of previously tested cells, shall be subjected to tests T.1 to T.5 and T.7.

Covers VRLA batteries, used as a reserve energy source that supports DC-powered telecommunications load equipment. Defines the proper operational use, storage conditions and test criteria initial and lifetime for VRLA cells (modules). Intended to be used to establish initial physical and performance characteristics of VRLA cells or modules, performance expectations throughout their lifetime and operations conditions for appropriate use and guidance for designers of these cells or modules.

The CWA provides guidance on the specification, installation and operation of flow batteries. It facilitates the pre-commercial phase when flow batteries need to be compared with other flow batteries or other electrical storage devices. It provides guidance to conformity assessment bodes to benchmark flow battery conformity with existing directives and other regulations.

The standard specifies marking, tests and requirements for sealed nickel cadmium prismatic secondary single cells.

The standard specifies marking, designation, dimensions, tests and requirements for vented Nickel Cadmium prismatic secondary single cells.
