Hazards – Conditions or processes that cause, or have the potential to cause, harm or loss to people and/or property. The hazard (undesirable event) produces adverse consequences and the possibility of an emergency. It is an event or physical condition that has the potential to cause fatalities, injuries, property damage, infrastructure damage, agricultural loss, damage to the environment, interruption of business or other types of harm or loss:
- A likely hazard is a hazard that has occurred in recent memory and is likely to occur again.
- A possible hazard is a hazard that has not occurred in recent memory, but could occur based on prior incidence or expert assessment (e.g., a nuclear facility incident, terrorism or earthquake).
- An unlikely hazard is a hazard that has never occurred, and will not likely occur (e.g., a mine emergency where there is no mine).
(a) A condition of a premises
(b) A substance, thing, plant or animal other than man or
(c) A solid, liquid or combination that has, or that is likely to have, an adverse effect on the health of any person
Hotline – Telephone line(s) set up to manage an increase in call volume to the organization on an emerging situation/problem of interest.
Impact – Expressed quantitatively or qualitatively, it is the estimated damage/loss to, or the ultimate effect on an entity as an outcome of an event caused by a hazard. This phase may last for moments (e.g., a tornado or crash) or for several days (e.g., a flood or forest fire).
Internal Emergency – An incident, such as a fire, power failure or bomb threat that occurs within the agency and affects staff’s safety and well-being and agency resources. The response to the incident may or may not impact on the agency’s overall ability to deliver programs and services.
Jurisdiction – The geographical area under the authority of Wellington-Dufferin-Guelph Public Health, comprising Wellington County, Dufferin County and the City of Guelph.
Mitigation/Prevention – Actions taken to eliminate or reduce the degree of long-term risk to human life, property and the environment from natural and technological hazards. Mitigation assumes that we are exposed to risks whether or not an emergency occurs. Mitigation measures include, but are not limited to, hazard and risk analysis, monitoring and inspection, public education, safety policies and procedures, building design, insurance, legislation and stocking emergency supplies.

Radiological Hazard – Possible contamination or undue exposure to atomic radiation.
Recall – Action taken to remove a product from the market.
Recovery – Activity that returns vital support systems to minimum operating standards and long-term activity designed to return life to normal or an improved level including some form of economic viability.

Response – Actions taken immediately before, during or directly after an emergency event to save lives, minimize damage to property and the environment, and enhance the effectiveness of recovery. Response measures include, but are not limited to, emergency plan and alert-system activation, emergency instructions to the public, emergency medical assistance, emergency operations centre staffing, senior management alerting, resource mobilization and warning systems activation.

Virulence – Severity of disease in a host expressed as a ratio of the number of cases of severe disease and fatalities divided by the total number infected.
Vulnerability – The degree of susceptibility to potential hazards in terms of damage or losses from such hazards as faced by a specific entity, the environment or population.
Warning – Applies mainly to emergencies with a more gradual onset– those that may be forecast. For instance, severe weather patterns and rising flood levels may be issued as warnings allowing time for preparation.
