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 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 |
| 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 |
| 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 |
| Air Sparging: |
The use of pressurised air, forced across a surface to breakaway and strip-off settled smoke, soot, lint, dust and other surface-borne contaminates from a surface. Mitigation Note: Air sparging is a method used in fire damage and dust-down remediation to remove contaminates and pollutants. Air sparging can be used in confined ceiling and attic spaces where general cleaning and HEPA vacuuming cannot be accomplished, or are not cost effective. Education Note: Quite often air sparging is more efficient than HEPA vacuuming and surface cleaning. The equipment for air sparging includes an air compressor as pressurized air, blown across a contaminated surface and aerosolized. The aerosolized particles must not be allowed to become free in the air without being directed to a collection device, airborne particulates must be captured down stream with negative air pressure and HEPA containment equipment (bag filters). The air compressor and forced wind is to be directed towards the negative air flow and HEPA containment vacuums. Safety Caution Note: 1) Do not under any circumstances use air sparging technology to aerosolize grains, flour and any other farm product in a confined space, or at all due to the potential for explosion. 2) Do not use air sparging technology if the mitigation employess are not properly fit with PAPR-type respirators and have appropriate PPE, and the air sparging environment is not completely sealed off from non-effected areas of the building. See PAPR, PPE |
| Air-mover (Airmover): |
A fan, pumpor other device that causes ear still, staticair to move forward resulting in forced air pressure. Education Note: a) In water damage and odour control air movers are used to vapourise surface water and odours. b) Forced air movement directs and suspends settled but not airborne contaminates to an outside source,dehumidifier, or air scrubber. c) Employees who use airmovers during the drying phase must do so with proper respirator and eye wear protection. d) Airmovers should only be used indoors after cleanup services have been completed. See Air Movement, Air Scrubber, Air Sparging, Allergies, Conjuctivitis, Dynamic Pressure, Pink-Eye, respirable Particles, Rhinitis. |
