An emergency is typically defined as an incident that poses an immediate threat to life, health, property, or the environment. It could also refer to an incident that has already caused loss of life or damage to health, property, or the environment. Emergencies are often classified based on their potential risk to life, health, or property. For example, ambulance services may categorize calls as immediately life-threatening, immediately health-threatening, or non-emergency. Emergency preparedness is crucial, and organizations should involve diverse representatives in the planning process. During an emergency, a designated coordinator should assess the situation, activate procedures, and coordinate with external emergency services. After the response phase, agencies may assist in recovery and implement mitigation measures to prevent recurrence.

What You'll Learn

Immediate threat to life, health, property, or environment
An emergency is defined as an urgent, unexpected, and dangerous situation that poses an immediate risk to life, health, property, or the environment. It requires immediate action and intervention to prevent the situation from worsening.
Life-threatening emergencies are the highest priority for most agencies, and they include situations such as natural disasters, medical emergencies, and incidents involving an active shooter. These emergencies demand prompt action and warnings to save lives and minimise physical damage. In the case of an active shooter, for instance, the Department of Homeland Security (DHS) advises attempting to evacuate the premises if there is an accessible escape path.
Health emergencies, the second highest priority, include incidents that may not be immediately life-threatening but have serious implications for an individual's continued health and well-being. These can include broken limbs, heart attacks, strokes, or trauma, requiring immediate intervention for proper recovery. Ambulance services often use the Advanced Medical Priority Dispatch System (AMPDS) to categorise calls as either 'A' (immediately life-threatening), 'B' (immediately health-threatening), or 'C' (non-emergency requiring a response).
Property damage or environmental emergencies are the third priority for emergency services. These emergencies may not always be considered genuine by all agencies, but they can have far-reaching consequences. Examples include forest fires, marine oil spills, and disasters resulting in large amounts of waste that threaten public health and the environment. The UNEP/OCHA Joint Environment Unit (JEU) provides services for rapid environmental assessments to identify and mitigate risks and impacts of large-scale disasters.

Loss of life, health detriments, property damage, or environmental damage
An emergency is an incident that poses an immediate threat to life, health, property, or the environment. It can also be classified as an emergency if it has already caused loss of life, health detriments, property damage, or environmental damage. In addition, an emergency could be a situation that has a high probability of escalating and causing immediate danger to life, health, property, or the environment.
Loss of life is the highest priority emergency, as most agencies agree that nothing is more important than human life. This includes situations such as cardiac arrest, suicide attempts, and severe allergic reactions. In these cases, it is crucial to call emergency services immediately and provide any necessary first aid, such as CPR or rescue breathing, if possible.
Health detriments refer to situations that are not immediately life-threatening but have serious implications for the continued health and well-being of individuals. This could include broken limbs, burns, smoke inhalation, or near drowning. While these incidents may not be life-threatening, immediate intervention is required to ensure proper recovery. Ambulance services often use a system like the Advanced Medical Priority Dispatch System (AMPDS) to categorise calls based on the level of threat to health.
Property damage refers to any incident that causes harm to physical possessions or structures. This could include damage to personal belongings, vehicles, buildings, or infrastructure. In the case of property damage, it is essential to assess the situation, notify the necessary authorities, and take appropriate action to prevent further damage.
Environmental damage pertains to incidents that negatively affect the natural environment or ecosystems. This could include natural disasters, such as tornadoes, hurricanes, or pandemics. In these situations, it is crucial to follow official guidelines and take the necessary precautions to ensure the safety of the community. This may involve evacuation procedures, seeking shelter in designated safe areas, or having emergency supplies readily available.

High probability of escalation to immediate danger
An incident that has a high probability of escalating and causing immediate danger to life, health, property, or the environment is considered an emergency. This includes situations that have not yet caused harm but are likely to do so if prompt action is not taken. For example, a fire that has not yet spread to multiple locations or injured anyone but has the potential to do so.
Agencies respond to emergencies by following a general protocol that prioritises incidents with the most potential risk to life, health, and property. This protocol involves a planning phase, a response phase, recovery, and mitigation. During the planning phase, agencies coordinate their response to avoid negative situations such as overlap or gaps in their emergency response plans. The response phase involves executing these plans, which may require improvisation due to the unique nature of each incident. After the incident, agencies assist in recovery by helping those affected overcome mental trauma and cleaning up the affected area. Finally, the mitigation phase involves taking steps to prevent reoccurrence and minimise potential damage in the future.
The classification of an incident as an emergency is crucial for determining the appropriate response. For instance, a fire department may respond to a non-emergency call about a cat stuck in a tree, where no lives, health, or property are at immediate risk. However, if there is a high probability that the situation could escalate and pose immediate danger, it would be classified as an emergency, warranting a prompt and prioritised response.
The definition of an emergency and the subsequent response can vary slightly depending on the agency and jurisdiction. In the United States, most states mandate that telephone books include a notice stating that someone must relinquish the use of a phone line if another person needs to report an emergency. This highlights the importance of prompt communication and the need to summon aid quickly in potential emergency situations.
Preparing for potential emergencies is essential for organisations and individuals alike. The Department of Homeland Security (DHS) provides guidance for evacuation during an active shooter situation, emphasising the need to evacuate the premises if there is an accessible escape path. Additionally, it is crucial to have a designated coordinator who is responsible for assessing the situation, activating emergency procedures, and making life-saving decisions. This individual should be known to all workers, and their role in coordinating with outside emergency services is vital.

Natural disasters
The impact of natural disasters on human health and safety is a critical aspect that warrants an emergency response. For instance, during and after a tornado, emergency response and recovery workers face various physical hazards, such as injuries from debris or exposure to hazardous substances. Similarly, hurricanes and storms can result in high winds and heavy rainfall, leading to flooding and creating multiple health and safety risks.
The functioning of critical infrastructure can be severely disrupted by natural disasters, interrupting essential day-to-day activities and endangering residents and workers in the affected areas. For example, a wildfire can rapidly spread and endanger lives, while a hurricane can cause widespread flooding, property damage, and infrastructure failure. In such scenarios, emergency response teams must be prepared to deal with the immediate threats to human life and health, as well as the protection of property and the environment.
To effectively manage natural disasters, comprehensive planning is vital. This includes identifying potential hazards, establishing emergency response protocols, and ensuring the safety of emergency responders. Agencies should work together to avoid overlaps or gaps in their response and recovery efforts. For instance, in the case of a hurricane, one agency might take the lead in coordinating emergency shelters, while another focuses on power restoration and infrastructure repairs.
Preparing for natural disasters is essential for individuals, communities, and organizations alike. Resources such as the Federal Emergency Management Agency (FEMA) and the Centers for Disease Control and Prevention (CDC) offer valuable guidance on emergency preparedness and response. By staying informed about potential hazards, developing emergency plans, and safeguarding critical documents and valuables, individuals and communities can enhance their resilience and ability to respond effectively during natural disasters.

Workplace emergencies
A workplace emergency is a situation that threatens workers, customers, or the public, disrupts or shuts down operations, or causes physical or environmental damage. They can occur anywhere and at any time, and they may strike unexpectedly. Emergencies can be natural, work-related, or external, and they can have varying impacts on employees, clients, and the public. Here are some detailed examples of workplace emergencies:
Natural Emergencies
Natural emergencies are challenging to predict and plan for and include events such as flooding, severe weather (hurricanes, tornadoes), and wildfires. These emergencies are not limited to a single workplace and can affect entire communities. Planning for natural emergencies should consider their potential impact on logistical responses.
Work-Related Emergencies
These emergencies arise from factors directly related to the work conducted in a specific industry or environment. They can include chemical spills, explosions, machinery malfunction, or dangerous gas releases. Work-related emergencies can have immediate consequences for the health and safety of workers and require prompt emergency responses.
External Emergencies
External emergencies stem from civil factors and are usually rarer than natural or work-related emergencies. However, they can be equally serious and include events such as protests, strikes, workplace violence, or harassment. These emergencies may not always pose immediate physical dangers but can severely disrupt operations and affect the well-being of employees and clients.
Health Emergencies
Health emergencies may not always be immediately life-threatening but can have serious implications for an individual's continued health and well-being. Examples include medical emergencies and natural disasters, as well as incidents like broken limbs, which require immediate intervention for proper recovery.
To effectively manage workplace emergencies, it is essential to have a comprehensive emergency action plan (EAP). This plan should involve conducting a hazard assessment, identifying risks, and outlining response procedures. Worker input and commitment are crucial for a successful EAP, and training workers to understand their roles and responsibilities within the plan can reduce injuries and damage during emergencies.
