Emergency Preparedness and Response Flashcards

According to OSHA standard 29 CFR 1910.38, which of the following is a mandatory element that must be included in a company's Emergency Action Plan (EAP)?

Answer: Procedures for reporting a fire or other emergency.

OSHA 29 CFR 1910.38(c) explicitly lists the minimum required elements of an Emergency Action Plan. These include procedures for reporting an emergency, evacuation procedures, procedures for critical operations, employee accountability, rescue/medical duties, and contact persons. Business continuity is a related but separate planning process, and off-site record location and next of kin lists are not mandatory components of the EAP itself.

During a large chemical spill at a manufacturing plant, response teams from the plant's emergency crew, the local fire department, and a third-party hazardous materials contractor are all on site. To ensure effective and coordinated management, the Incident Command System (ICS) is implemented. Which ICS principle is specifically designed to prevent confusion by ensuring that each responder reports to only one supervisor?

Answer: Unity of Command

Unity of Command is the ICS principle stating that each individual involved in incident operations reports to only one supervisor. This eliminates confusion from receiving conflicting orders. Unified Command allows different agencies to work together at a high level, Span of Control refers to the number of subordinates a supervisor can effectively manage, and Modular Organization allows the structure to expand or contract as needed.

Which of the following is the PRIMARY objective of conducting regular emergency response drills and exercises at a workplace?

Answer: To evaluate the effectiveness of the emergency plan and identify areas for improvement.

The primary goal of emergency drills is to test the emergency plan in a controlled setting to see how well it works and to identify gaps, weaknesses, or areas needing improvement in procedures, equipment, or personnel training. While drills may help satisfy insurance or regulatory requirements, their main purpose from an HSE perspective is performance evaluation and continuous improvement.

A chemical facility receives a warning of an imminent external atmospheric release of a toxic gas from an adjacent industrial plant. The wind is blowing the plume directly towards the facility, and the substance is known to dissipate within an hour. What is the MOST appropriate immediate protective action for the facility's employees?

Answer: Initiate a shelter-in-place protocol, securing all doors, windows, and ventilation systems.

For an external, short-duration toxic airborne hazard, sheltering-in-place is the preferred protective action. This strategy uses the building as a barrier, preventing personnel from moving through the contaminated plume during an evacuation. Evacuating would likely expose them to the hazard, while continuing normal operations is unsafe.

An employee discovers a fire in a trash can containing paper and cardboard. A nearby computer monitor has also caught fire and is sparking. Which type of fire extinguisher is suitable for safely and effectively combating BOTH of these fire classes?

Answer: ABC Dry Chemical

The fire involves two different classes: Class A (ordinary combustibles like paper) and Class C (energized electrical equipment like the computer). An ABC dry chemical extinguisher is rated for Class A, B, and C fires, making it the correct choice for both hazards. A water extinguisher is unsafe for Class C fires due to shock hazard, Class K is for cooking oils, and Class D is for combustible metals.

Following the conclusion of an emergency response drill or an actual incident, what is a critical next step for the response team and management to ensure continuous improvement?

Answer: Conduct a debriefing or 'hot wash' to discuss what went well and identify lessons learned.

A post-incident debriefing, often called a 'hot wash,' is a crucial step for learning and improvement. It allows all participants to discuss the response, identify strengths and weaknesses in the plan and its execution, and develop corrective actions to improve future performance. While replacing supplies is necessary, the debriefing process is essential for organizational learning.
