Odor Control >> Fire Smoke Smell From Apartment

The conservators' first assignment was to clean one gallery (the Earth Sciences Gallery) so that the museum could reopen as quickly as possible. On the third week following the fire, building cleaners had Fire Smoke Smell From Apartment completed their first and second cleaning passes, and it was possible for the conservation crew to begin the tedious task of cleaning all of the collection and display material in the gallery (fig. 5). Portable lights were still required during the cleaning because lighting could not be installed until after construction in the gallery was completed.
Installation of lighting fixtures was one of the last stages of the construction.The procedures used in cleaning the Earth Sciences gallery became the basis for the development of procedures for soot removal that were used throughout the recovery. Although different Fire Smoke Smell From Apartment surfaces responded very differently to cleaning depending on the degree of soot coverage and the material the artifact was made of, all surfaces responded best to a strict progressive cleaning procedure that involved direct vacuum (which had already been done during initial salvage but was often repeated again in recovery to remove more soot), dry-surface-cleaning techniques, and then wet-cleaning, if necessary.
 For example, a painted acrylic canvas backdrop marouflaged to Gyproc board was cleaned by direct vacuuming (twice); then soot Fire Smoke Smell From Apartment sponges were used to pull off almost all of the remaining soot, and wet-cleaning was not necessary. A glacier exhibit constructed of varnished acrylic paint on a canvas backdrop and a molded plastic base was cleaned by direct vacuum followed by the use of soot sponges and wet-cleaning with 1% ammonium hydroxide in water applied on sponges with a water rinse to the backdrop (fig. 6).
 A fossil concretion received two direct vacuums (the second using an attachment of a thin plastic tubing to reach into interstices), was dry-surface-cleaned with Groom/Stick applied by hand and on the end Fire Smoke Smell From Apartment of a paintbrush, and then required wet-cleaning using 2% Orvus (v/v) foam on swabs with a water rinse (fig. 7). In general, vacuuming and dry-surface-cleaning removed the largest quantities of soot, and wet-cleaning (normally detergent or surfactant in water) was used sparingly to remove the soot that was intricately tied with the surface. "Bulk” cleaning techniques were used in some circumstances.
 Large amounts of plastic foliage in dioramas were removed, placed in the back of a truck, and put through a commercial car wash. Other foliage was hand dipped and sponged in large plastic garbage cans filled Fire Smoke Smell From Apartment with a dilute solution of Orvus in water, and then rinsed. Replica tree trunks were cleaned out of doors using Orvus in water and a garden hose. The 7,800 sq. ft. Earth Sciences Gallery was recovered in 93 days; this aspect of the project involved cleaning the gallery, displays, and artifacts, painting the gallery walls, and replacing some exhibit and nonexhibit elements, such as ceiling, carpet, and lighting fixtures.
Table 2 summarizes some of the materials that were used to clean various surfaces. Table 3 compares the treatment time required for displays Fire Smoke Smell From Apartment of various museum objects. After technical staff were hired, it was possible to expand the museum recovery efforts to other areas of the gallery and into warehouses and to begin cleaning the noncollection material that had been removed from the building. Cleaning took place in the First Nations Gallery on those displays that would not be replaced.
In one case, a diorama backdrop near the fire was thoroughly cleaned with direct vacuum and soot sponges (fig. 8). The lower half, Fire Smoke Smell From Apartment which was only moderately sooty, was solvent-cleaned using 2% ammonium hydroxide in water applied on sponges with a water rinse. The upper half, which was black with soot, was washed down with paint thinner on sponges and then prepared with layers of gesso for repainting by the artist. Foreground material was removed from the Life Sciences Gallery in countless trips using wheelbarrows to discard the material outside.
 The stripped dioramas were left with sooty animals and backdrops, Fire Smoke Smell From Apartment which were cleaned with the direct application of a vacuum nozzle until they could be cleaned more thoroughly. Boxes of education material and other items were cleaned by technicians in an off-site warehouse (fig. 9). To remove soot from these noncollection materials, bulk cleaning treatments were carried out, involving the use of conservation and household cleaning materials. All objects were first vacuumed and then cleaned in the quickest possible fashion.
 For example, paper objects were cleaned in a tray holding a small Fire Smoke Smell From Apartment layer of eraser powder so that the objects could be rubbed with the powder in assembly-line fashion, and then removed from the tray so that the powder could be brushed and vacuumed away. A much-used resource library was also cleaned. Technical staff were shown how to clean the limited variety of surfaces and proceeded in an assembly-line fashion. Due to the tight packing of books on the shelves, soot had not generally filtered between the pages.
 Book covers were direct-vacuumed, and then the text blocks were vacuumed while holding the covers tightly to avoid soot Fire Smoke Smell From Apartment penetration into the pages. Dry-surface-cleaning techniques were then applied: the text block was cleaned with erasers or soot sponges, and the cover was wiped with Webril Wipes or soot sponges. Small pamphlets were direct-vacuumed and then carefully cleaned by rubbing with eraser powder in a shallow plastic tray or paint tray that held a small amount of eraser powder. The powder was then brushed and vacuumed away.
The bird mount collection of 1,500 specimens, stored in closed cabinets in rooms far from the fire, had only a dusting of soot. The birds Fire Smoke Smell From Apartment were cleaned using a variety of tools, but time constraints precluded use of vacuum in most cases. Wood bases were cleaned with a Hake brush, soot sponge, and Groom/Stick. Using an old taxidermy trick, an owl wing was waved through the air in a whisking motion to blow loose particles free from feathers.
The owl wing was then brushed gently over the surface of the Fire Smoke Smell From Apartment object. Webril Wipe, cut into 1 in. wide strips, was rolled several layers thick onto a wooden stick and brushed gently over the feathers. Soiled Webril was removed one layer at a time (fig. 10). Tweezers and dental tools were used for some feather realignment. Eyes, feet, and legs were cleaned as needed with Groom/Stick, ethanol, 2% Orvus (v/v) in a water rinse, or distilled water.
