OSHA’s proposed Incident Management System (IMS) requirements

Workplace Emergency Response Employers (WEREs) and Emergency Services Organizations (ESOs) respond to a wide variety of incidents, most of which are considered routine and involve a small commitment of resources. Some incidents are more complex and involve larger commitments of resources and potentially higher-risk operations. The WERE and ESO need to develop an incident management system (IMS) that accommodates all types and sizes of incidents and provides for a systematic process of escalation from the arrival of the first units at a routine incident, to an appropriate response to larger and more complex incidents.

The proposed rule defines an IMS as

“a system used for managing and directing incident scene operations and activities. It includes establishing functions for managing incidents, describes the roles and responsibilities to be assumed by team members and responders, and standard operating procedures to be utilized.”

Because OSHA is aware that some WERTs and ESOs use the terms IMS and Incident Command System (ICS) synonymously, the definition also indicates that incident command is a functional component of the IMS.

An IMS provides for the safety and health of team members and responders by establishing structure and coordination for the management of emergency incident operations. Lack of, or deficiencies in, an IMS are routinely cited by NIOSH in their investigation reports for team member and responder injuries and fatalities.  Examples of deficiencies noted include multiple team members and responders serving in command roles in an uncoordinated manner, lack of an established accountability system for tracking team members and responders, not establishing a rapid intervention crew (RIC), and not designating an Incident Safety Officer (ISO) or otherwise ensuring for the safety and health of team members and responders.

Paragraphs (o)(1)(i), (ii), and (iii) of the proposed rule would require that each WERE and ESO develop and implement an IMS to manage emergency incidents based on the type and level of service(s), the facility or community vulnerability assessment, and the pre-incident plans.

An IMS provides a standard approach to managing the broad range of emergency incidents that team members and responders may encounter. The IC should be able to apply the IMS in a manner that supports the effective and efficient management of the incident. Each WERE and ESO should evaluate existing systems as it develops and implements an IMS that meets its own requirements and provides compatibility with systems used by mutual aid WERTs and ESOs, and other agencies that it would reasonably be expected to work with at emergency incidents.

 

Proposed paragraph (o)(2)(i) would require that WEREs and ESOs ensure that their IMS include flexible and scalable components that are adaptable to any situation.

A note included with the proposed provision indicates that standardization of the IMS, such as provided in the NIMS and the National Response Framework (NRF), developed by FEMA, an agency of the U.S. Department of Homeland Security, is essential to the successful coordination and function of WERTs and ESOs in incident response operations. The NRF provides guidance for how the nation responds to all types of disasters and emergencies. It is built on scalable, flexible, and adaptable concepts identified in the NIMS to align key roles and responsibilities. The NIMS guides WERTs and ESOs with shared vocabulary, systems, and processes for working effectively together at emergency incidents.

 

Paragraph (o)(2)(ii) of the proposed rule would require that each WERE and ESO ensure that, in the absence of a dedicated ISO, the IC assesses the incident scene for existing and potential hazards and oversees incident safety.

Many incidents have an ISO whose primary responsibilities are to assess the incident scene for existing and potential hazards and oversee incident safety. Small-scale incident scenes, however, may not have a team member or responder who is designated as the ISO. In these circumstances, the IC would need to oversee incident safety.

 

Paragraph (o)(2)(iii) of the proposed rule would require that each WERE and ESO ensure that the IMS includes a means for team members or responders to notify the IC or Unified Command (UC) of unsafe conditions and actions on the incident scene.

Unsafe conditions or actions may become evident to team members and responders while they are performing their duties. It is important that they be able to alert the ISO, IC or UC as soon as possible, by means of portable radio, cell phone, face-to-face communication, or another method designated in the IMS, so that actions can be taken by the IC or UC to address the hazard.

 

Paragraph (o)(2)(iv) of the proposed rule would require that each WERE and ESO ensure that the IMS consists of collaborative components that provide the basis for clear communication and effective operations.

Components, such as those identified in the NIMS – resource management, command and coordination, and communications and information management – would provide structure and coordination for ICs and UCs to manage emergency incident operations, which would provide for the safety and health of team members and responders.

 

Proposed paragraphs (o)(3)(i)-(iii) would require that each WERE and ESO designate the responsibilities of the IC that at least include front-line management of the incident, overall incident safety, and tactical planning and execution. The front-line management of the incident could include activities such as establishing a command post, conducting size-ups of the incident, and controlling incident communications. The overall incident safety responsibility of the IC could cover activities such as including team member and responder safety in the IAP, and continuously assessing the risk to the safety and health of team members and responders. The tactical planning and execution could include activities such as developing an overall strategy and an IAP, assigning duties and tasks to team members and responders, establishing hazard control zones, maintaining resource and team member or responder accountability, and updating the IAP as needed.

 

Under proposed paragraph (o)(3)(iv), the WERE and ESO would also designate to the IC the responsibility of determining if additional assistance is needed, and relaying requests for internal resources, mutual aid, and skilled support assistance through the emergency communications and dispatch center.

The IC is in the best position to know what and when additional assistance is needed. Assistance is requested by the IC through the dispatch center which would contact the requested internal resources, mutual aid WERT or ESO, or the employer who can provide the requested skilled support.

 

Paragraph (o)(4) of the proposed rule would require that each WERE and ESO ensure that the IC has the training and authority to perform IC duties.

Training would vary depending on the team member’s or responder’s tier of duty. For example, NFPA 1021, Standard for Fire Officer Professional Qualifications, 2020 ed., identifies four levels for minimum requirements for leadership and supervision over others and operations, which includes incident management. Level 1 is a tier for an entry level/first-line supervisor, ESO “company officer,” or team leader. Level 4 is the top level or top tier for the chief of the ESO. On a single unit response incident, typically the senior team member or responder would be the IC. On a multi-unit response incident, the senior team member or responder could be the initial IC, but the role of IC would pass up the chain of command as more senior/higher tier team members or responders arrive on the scene.

 

Additionally, as part of the IMS, the WERE and ESO would need to authorize the appropriate team members and responders to serve as an IC. Many of the provisions in this section are based on, or are consistent with, NFPA 1500, and NFPA 1561, Standard on Emergency Services Incident Management System and Command Safety, 2024 ed. OSHA has preliminarily determined that development and use of an IMS would make incident scenes safer and prevent injuries and fatalities.
