ABSTRACT:
BACKGROUND OF THE INVENTION
The building industry including home construction involves fiber glass material being used as insulation above the ceilings and in the walls. This insulation can be either blown in place or sheet laid. The insulation material in either case produces particles injurious to a person's skin, nose, lungs and eyes. Conventionally, protection against the fiber glass particles involves the workman wearing goggles and rubber gloves on the hands. This procedure does not work satisfactorily as the particles can contact the unprotected part of the workman's body and seep behind the goggles through small openings. The rubber gloves interfere with finger gripping of tools and building materials.
What is needed is a garment that will fully protect the person's body but yet allow for complete vision and use of the hands including the fingers.
SUMMARY OF THE INVENTION
A first garment is provided that is open at one end and closed at the other and is pulled down over the head and torso with the arms and hands being inserted into sleeves that include protection for the hands and fingers. The material in the garment is thin and stretchable such that it matingly fits all surfaces of the person's body. The thinness of the material also allows the person to see through it to allow working with the fiber glass material.
Various materials may have properties allowing for sufficient stretch and be thin enough to see through while preventing fiber glass particles from penetrating through the material. One material that has been found acceptable is the stretchable nylon material used in women's pantyhose such as made by Hanes Hosewear, Osage, Iowa, or Jockey International, Inc., Kenosha, Wis. The material used in this garment varies from 75 percent nylon, 25 percent Lycra® spandex to 85 percent nylon, 15 percent Lycra® spandex (20 denier). As the material is stretched over the body including the eyes, it becomes thinner allowing for clear vision. The material lightest in color will provide for the best vision. This material will also allow air to flow freely through it, thus allowing the person to breathe freely.
The nature of this material and the way it fits over the face is such that in an extreme case tobacco products could even be used. The garment is also stretchable to allow fitting over the workman's normal work clothing. A second garment is provided for the waist down and overlaps with the upper garment at the waist, thereby protecting the entire body against skin contact with fiber glass particles.
Removal of the garments is performed in such a way that the fiber glass particles attached to the outside surface of the garments are trapped in the garment as the upper garment is pulled upwardly over the torso turning the garment inside out. The same removal step is performed with the lower garment, i.e., it is pulled downwardly turning inside out thereby trapping the fiber glass particles in the garment which is then discarded.
