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
| Abrasive: |
A more course or harder material that is capable of debriding the surface of another material, such as sand paper. An abrasive can be a soft abrasive which, when mixed with water, allows for gentle surface cleansing, such as scouring powder, baking soda or Soft-Scrub (TM) |
| Abrasive Blasting: |
A process by which compressed air and a mixture of particulate materials are forced across or on to another surface, for the purpose of removing a material or contaminate. See Air Blasting, Air Sparging |
| Abrasive Cleaner: |
A substance such as a powdered cleaner having a scouring effect, which is used to remove surface contaminates and loose stains. Abrasive cleaners must be tested to insure that they will not harm, discolour or damage a material surface. Mitigation Note: Abrasive cleaners are very important in the structural breakdown of Gram-negative bacteria cell structure in sewage blackwater contamination of non-porous building materials. |
| Air Blasting: |
The process of using pressurised air and different size tips and nozzles, to force and dislodge surface materials and contaminates. See Abrasive Cleaning, Air Sparging |
| Mechanical Agitation: |
The preferred method of cleaning a contaminated surface properly. Mitigation Note: a) Counter and wall mechanical agitation includes scrub brushes, detergents, warm water and rinsing. b) Mechanical agitation of floors preferably include a floor scrubber with an abrasive stripping pad, detergents, warm water and rinsing. c) There is a difference of mechanical agitation of a non-porous surface and a porous surface. A non-porous surface such as stainless steel and vinyl flooring, can be cleaned and sanitized having a even cleanliness, while porous surfaces, such as non-sealed concrete, wood subfloors and drywall, cannot be cleaned and sanitized evenly. |
| Scouring: |
The removal or purging of unconsolidated matter by hard rubbing, cleaning, or abrasive action. |
| Scrubbing: |
The washing of a floor or material through wetting, detergent solution and a moderately abrasive pad or brush. The method must take into consideration the appropriate detergent and brushes for the surface involved. Scrubbing requires vigorous agitation of the wetted surface. |
