Description

    FIELD OF INVENTION
  • This invention relates generally to the field of debris collection and containment devices, and in particular with a debris containment device that is easily adapted for use with standard vacuum cleaners and suction devices known in the art.
  • BRIEF DESCRIPTION OF THE DRAWINGS

  • BACKGROUND
  • Vacuum cleaner and suction devices are known in the art for cleaning, filtration, evidence collection and various forensic uses. These systems often include receptacles, and various types of filters. However, most of these devices are in use in laboratories, and have specialized applications and markets.
  • However, there is a need for a convenient containment and debris disposal device that is adapted for use for in domestic, commercial and other non-laboratory settings. For example, such a device may be used for cleanup of broken fluorescent light bulbs which are increasing in popularity and which emanate fine mercury particles and gaseous mercury vapor. Additionally, in both residential and commercial settings special clean-up issues may be presented by insecticide residue, insect bodies and larvae, rodent hair and feces, urine, blood, feces, bodily fluids, and other materials that would contaminate or de-sanitize a vacuum cleaner.
  • With respect to collection and disposal of broken compact fluorescent lamps, there are particular hazards related to mercury contamination which make traditional vacuum cleaners unsuitable. Commonly, when fluorescent bulbs are broken, mercury vapors are emitted from the fluorescent lamps and contaminate the immediate area and eventually evaporate, exposing increasingly distal areas to mercury vapor.
  • Presently, the DOE website and EPA advise consumers to pick up large glass pieces and to seal them in a glass container for removal to a waste facility. Smaller glass and dust pieces too small for manual cleanup may be removed using stiff pieces of paper such as index cards, the sticky side of tape, and/or use a damp paper towel to pick up the finest particles. However, these procedures are impractical for soft or textured surfaces like carpet. For areas like carpet where cleanup is most difficult, the Maine EPA, which has done a specific study on this topic, suggests consumers may consider removing throw rugs or that area of carpet where the breakage occurred. This report further recommends not using a vacuum cleaner itself to avoid contaminating the vacuum cleaner and dispersing the mercury vapor throughout the room.
  • Current cleanup methods of broken fluorescent bulbs do not specifically include using a vacuum cleaner to pick up the broken glass pieces and mercury. The concern of unfiltered mercury spreading through the air and contaminating it and the vacuum are serious concerns. To contain the released mercury and prevent dissemination, broken parts must be effectively captured and contained, and circulating air must be filtered to capture gaseous mercury vapors.
  • Additionally, other materials that may or may not be hazardous to humans may present special clean-up issues which are not effectively addressed by commercially available vacuum cleaners and attachments known in the art. For example, pollutants (such as rodent and bird droppings) or bio-hazardous materials may emanate harmful airborne matter and vapors. Other examples with special clean-up issues include various electrically conductive materials, fine particulates viscous materials and adhesives that may damage a vacuum cleaner or compromise hoses, fittings and other parts.
  • Some substances in fine particulate state, such as powder coating paint substances and baking flour, may possess explosive or combustible properties if drawn through or into vacuum. (The process of moving these substances as well as the collection presents a risk of combustion).
  • Moreover, in some manufacturing environments, valuable materials, pharmaceuticals and small parts may be dropped, and it is desirable to use a vacuum cleaner to retrieve the items themselves from mixing or being contaminated by other items in the vacuum cleaner device.
  • It is desirable to introduce a containment device into the market which is inexpensive, lightweight, fully or partially disposable and easily adapted for a variety of commonly sold vacuum cleaner devices.
  • It is further desirable that such a device capture all harmful substances using a standard vacuum cleaner device, and control the recovery of such substances for proper disposal and/or for further tracking and analysis.
  • It is further desirable that such a device prevent contaminants from entering components of the vacuum cleaning device (in particular the hose and motor).
