Disaster recovery and restoration can be veiled in mystery to the many who have not undertaken specific training. This glossary explains technical terms to assist both report writing and the understanding of those technical terms so often misunderstood.
Definition
| Asphyxiant: |
A substance or chemical causing suffocation by removal or exclusion of oxygen, preventing oxygen absorption, or preventing oxygen use in the tissues. |
| Asphyxiating Atmospheres: |
An atmosphere which a chemical or other substance can absorb the oxygen in air as a result of a chemical reaction or other reaction, including gases that inert the atmosphere, consuming the breathable oxygen. Health and Safety Note: Chemicals used to mist and fog in the atmosphere, chemicals that are allowed to evaporate, and the use of ozone are asphyxiants. As dangerous and seldom recognized as an asphyxiant, are power generators giving off carbon monoxide gas. See Confined Space, Permit Required Confined Space, Toxic Air Contaminates |
| Gas: |
A colourless and often odourless airborne substance. A form that is neither liquid or solid, but can be described as a vapour. Some gases are flammable, and can be a poison, irritant or an asphyxiant. See Oxygen |
| Immediate Danger to Life and Health (IDLH): |
a) The maximum air concentration of a chemical substance from which a healthy person could escape within a 30-minute exposure without irreversible adverse health effects or experiencing impaired health conditions. b) An atmospheric concentration of any toxic, corrosive or asphyxiant substance that poses an immediate threat to life or would cause irreversible or delayed adverse health effects or would interfere with an individual's ability to escape from a dangerous atmosphere. Health and Safety Note: Any other atmospheric condition that is immediately dangerous to live or health, is an immediate hazard that must be avoided. IDLH means any condition that is an immediate or delayed threat to life; or that would cause permanent, negative health effects; or that would interfere with a worker's ability to escape or leave a work area without help. |
