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
| Absorb: |
In water damages, the temporary ability of porous building materials and contents to absorb (hold and retain) liquid water and water vapour for periods of time. Education Note:Like a sponge, most absorbent materials are able to give up their water when atmospheric conditions are desirable or when forced to through dynamic pressure. See Absorbant, Air Dynamics |
| Absorbent: |
Any material that has an affinity for certain substances and attracts these substances from a liquid or gas state with which it is in contract. A substance that attracts and holds quantities of water vapour or a liquid. |
| Absorption Chiller: |
A heat operated refrigeration unit that uses an absorbent (lithium bromide) as a secondary fluid to absorb the primary fluid (water), which is a gaseous refrigerant in the evaporator. |
| Activated Carbon : |
Carbon charcoal that has an increased absorptive capacity of retaining chemicals, vapours, hydrocarbons, and sometoxins from a contaminated environment. Education Note: Scrubbing contaminated indoor air with an air scrubber having an activated carbon (charcoal-based) filter, are capable of trapping and reducing organic vapours in a building. Activated charcoal is commonly used as a gas vapour absorbent in air-prifying respirators and as a solid sorbent in air-sampling. See Adsorbent, Air Scrubbers, Air Sparging |
| Adsorbent: |
The incorporation of a liquid or energy absorbed into another substance. Absorbent of a substance can be a permanent change to the building material, such as sewage contamination, fire, odour or pesticide exposure. Education Note: For example, the rate of absorbency of drywall to absorb a substance or a vapour will, most likely, cause permanent damage to the drywall material. Note: 'Absorbent' means to melecularly bond together. See Absorbent, Absorption |
| Adsorbent Sampling: |
One of a number of absorbent materials used to collect a contaminate. Education Note: Absorbent samopling, such as from a carbon-type of sorbent sample media allows the collection of chemicals, gases and vapours. After collection they (the contaminates) absorbed in a laboratory usually through GC/MS/FID. See Air Sampling, Bulk Material Sampling, Soil Sampling, Surface Sampling, swab Sampling, Wipe Sampling, Vacuum sampling |
