7.3 Emergency Action Plans (EAP) & Incident Command System (ICS)

Emergency Action Plans (EAP) & Incident Command System (ICS)

Workplace emergencies can strike at any moment, ranging from fires and chemical spills to active shooter situations and natural disasters. The primary goal of emergency preparedness is to ensure the preservation of life, followed by the protection of property and the environment. Occupational Hygiene and Safety Technicians must be adept at evaluating, developing, and auditing Emergency Action Plans (EAPs) and understanding how internal emergency responses integrate with external emergency services through the Incident Command System (ICS). This section details the regulatory requirements, practical implementation, and organizational structures necessary to effectively manage crisis situations.

OSHA Requirements for Emergency Action Plans (EAP)

Under OSHA standard 29 CFR 1910.38, employers are required to develop a comprehensive Emergency Action Plan to guide employee actions during workplace emergencies. The plan must be kept in the workplace and be available for employee review. Notably, employers with 10 or fewer employees may communicate the plan orally, but employers with more than 10 employees must maintain a written document.

A compliant and effective EAP must include, at a minimum, the following core elements:

1. Procedures for Reporting: Clear instructions on how to report a fire or other emergency (e.g., dialing 911, activating internal pull stations, or using a specific radio channel).
2. Evacuation Procedures and Route Assignments: Detailed escape route diagrams, including primary and secondary evacuation paths, clearly marked exits, and designated assembly areas outside the hazard zone.
3. Procedures for Critical Plant Operations: Guidelines for employees who must remain behind temporarily to operate or shut down critical plant equipment (e.g., shutting off gas valves or securing power grids) before they evacuate.
4. Accounting for All Employees: A systematic method to account for all employees, visitors, and contractors after an evacuation has been completed. This is crucial for informing emergency responders if search and rescue operations are necessary.
5. Rescue and Medical Duties: Specific procedures and designated personnel responsible for performing rescue operations and administering first aid/CPR, provided they are properly trained and equipped.
6. Names and Titles of Contacts: A list of individuals or job titles who can be contacted by employees for further information or clarification about the plan.

Employers are obligated to train employees on the EAP initially upon hire, whenever the employee's responsibilities under the plan change, and whenever the plan itself is updated. Regular emergency drills should be conducted to evaluate the effectiveness of the plan and familiarize employees with evacuation procedures.

Alarm Systems and Communication

An EAP is useless if employees are unaware that an emergency is occurring. OSHA standard 1910.165 requires employers to install and maintain an employee alarm system. The alarm must be distinctive and recognizable as a signal to evacuate or perform specific actions under the EAP. It must be loud enough or bright enough to be perceived above ambient noise or light levels by all employees, including those with hearing or visual impairments. Modern systems often combine audible sirens or voice announcements with visual strobe lights.

The Incident Command System (ICS)

When emergencies escalate beyond minor incidents, a structured management system is required to coordinate the response. The Incident Command System (ICS) is a standardized, on-scene, all-hazards incident management framework developed by the federal government and adopted nationwide by emergency response agencies (fire, police, EMS) and private industries.

The ICS provides a flexible organizational structure that can expand or contract depending on the size and complexity of the incident. It establishes a common terminology, enabling disparate agencies and departments to communicate effectively and work together seamlessly.

The Five Major Functional Areas of ICS

The ICS organization is built around five major management functions:

1. Incident Command: The Incident Commander (IC) is the individual responsible for the overall management of the incident. The IC establishes objectives, strategies, and priorities. In a private facility, the initial IC is often a safety manager or shift supervisor until external emergency services arrive and assume command.
2. Operations Section: Responsible for executing the tactical operations necessary to fulfill the Incident Action Plan (IAP). This section directs all resources deployed in the field, such as internal fire brigades or spill response teams.
3. Planning Section: Responsible for the collection, evaluation, and dissemination of information related to the incident. This section tracks resources, anticipates future needs, and develops the formal Incident Action Plan for subsequent operational periods.
4. Logistics Section: Provides the necessary facilities, services, and materials to support the incident response. This includes arranging for food, medical support, communications equipment, and transportation for the responders.
5. Finance/Administration Section: Tracks all costs associated with the incident, including personnel time, equipment procurement, and compensation claims. This is vital for cost recovery and budget management following a major crisis.

Key Principles of ICS

Several core principles ensure the ICS functions effectively under extreme stress:

• Span of Control: This refers to the number of individuals or resources that one supervisor can manage effectively. In ICS, an effective span of control ranges from three to seven subordinates, with five being the optimal number. If a supervisor has more than seven direct reports, the organization should be expanded with additional layers of supervision (e.g., creating branches or divisions).
• Unity of Command: Every individual participating in the response reports to only one designated supervisor. This eliminates conflicting orders and confusion.
• Unified Command: In incidents involving multiple jurisdictions or agencies with overlapping authorities (e.g., a massive chemical spill involving local fire departments, state environmental agencies, and federal regulators), a Unified Command allows these agencies to manage the incident collaboratively by establishing a single set of objectives without compromising their respective authorities.
• Common Terminology: ICS mandates the use of plain language and standard terminology for organizational functions, resource descriptions, and incident facilities. Radio codes and obscure acronyms are strictly prohibited to prevent miscommunication during joint operations.

By integrating internal Emergency Action Plans with the principles of the Incident Command System, safety professionals ensure that their organizations are prepared to respond to localized emergencies and are capable of interfacing smoothly with external first responders during major disasters.
