Many requests have been received for example photos of asbestos ceiling tile and ceiling panels. Shown above is one example of an asbestos-containing suspended ceiling panel, one of many types, which are found in a seemingly countless array of surface patterns and textures. More examples of asbestos ceiling tile and panels will be offered for visual reference in some upcoming photos.
Ceiling tiles and panels are utilized to serve a variety of useful purposes, such as providing a level of fire-rated protection, absorb sound, conceal unsightly utility systems or cover over older building finishes, create air plenum spaces for HVAC operation, reduce total usable air volumes in occupied areas for HVAC efficiency, maintain a level of insulation value between building zones, and provide a simple decorative appearance.
This small section of non-descript ceiling panel with fractured edges is roughly about a quarter of a 2-ft. x 4-ft. panel that was formerly installed in a suspended ceiling grid or drop-ceiling system. A 1-inch cube has been placed for visual scale.
The panel section shows moisture staining on an otherwise smooth, white surface and also demonstrates a fairly common style of patterned perforations across its entire surface. The tiny pinholes and fissures provide an acoustic absorption value, one of the main purposes of practically all ceiling tiles and panels. Closer study of the panel's surface pattern reveals that there are two sizes of pinholes and that the fissures or crevices are oriented in a latitudinal direction.
Distinctions in a ceiling tile's appearance, however subtle, is an important factor when visually evaluating many tile materials with very similar visible charcteristics. Oftentimes, in the event that ceiling tiles and panels require replacement, building maintenance personnel attempt to match existing patterns as close as possible, which can be problematic to discern differences during an asbestos survey inspection.
Although not particularly evident about this rather ordinary-looking ceiling panel, especially from this view as most would see it suspended above their heads, it has been laboratory-tested and identified to contain approximately 5%-10% amosite asbestos.
To compound matters concerning ceiling tile and panels, as most who've dealt with this crumbly and messy material probably already know, the typical ceiling tile is indeed quite friable in its composition and is practically always considered a suspect material during an asbestos survey. The crumbly ceiling tile material can be very troublesome when contending with asbestos issues.
In the U.S., ceiling tile and ceiling panels are generally categorized by regulatory agencies as a "miscellaneous" material. When trying to deal with the removal of suspect ceiling tile/panels of unknown asbestos content, an accepted practice and conservative recommendation is to "assume" and treat the friable suspect ceiling tile material as asbestos until conclusive testing confirms either the presence or absence of asbestos via specialized laboratory microscopy methods (such as PLM), then treat accordingly.
Bulk samples of suspect asbestos materials should be collected by an experienced, trained, qualified, certified, and accredited inspector/surveyor for proper testing; proper removal and disposal of asbestos materials should be performed by trained, certified, and accredited/licensed asbestos abatement personnel.
Overview of the reverse-side of an asbestos ceiling panel section, formerly installed as a 2-ft. x 4-ft. suspended panel. Printed product labeling on this example indicates "FIRE-RATED - PROTECTONE F - Acoustical Panel - Replace Only With Equal". A 1-inch cube is shown for visual scale; discoloration is from moisture staining.
View of printed product labeling on reverse-side of an asbestos ceiling panel section, formerly a 2-ft. x 4-ft. panel. Although labeling is not often seen on many ceiling tile or panels, the labeling on this example indicates "FIRE-RATED - PROTECTONE F - Acoustical Panel - Replace Only With Equal".
Even at a distance of only a few inches away from the backside of the panel, one can begin to depict tiny "line fragments" on the grainy, porous surface. Inset shows closer study of the panel's surface with more discernible fibrous features, amosite asbestos fiber bundles embedded within the panel's artificial fiber matrix. Additionally, tiny beads of melted artificial fiber material are also visible in the inset, created during manufacture of the panel.

The hot sauce and food are both great things at Tijuana Flats, but the ceiling and artwork on the wall is also something to see.

Last year I bought a big, weird house and I'm madly in love with it. I spend about 90% of my waking hours in the kitchen, and I think that's normal - please don't tell me if I'm wrong.
The 7500 series 3M respirator paired with the P100 filter worked great. The Dewalt goggles were good too, I'm just sweaty so they got a bit wet inside.
#Ceiling - A glass globe completely surrounds the bulbs except where it connects with the neck or mother, or a glass plate can sit under the bulbs. Either design allows light to shine upward, to some extent and drop ceiling lighting bouncing off the roof to provide light from multiple angles. These...

This abandoned grocery store has played host to some graffiti taggers as well as, most likely, midnight shoppers and fly dumpers from nearby mines. Seen in April 2022.

Anthony & John Old House Last Day 1986 80s - As we were handing over the keys to the new owners of the property, I grabbed my Minolta XE-7 camera w/ 20mm lens, placed it on the floor and I told my brother John to pose in our parlor corner. Our Christmas tree had stood here for many years. It was one of the saddest days in my life. It was as if a family member had died. I am not exaggerating here. These windows are from 1855. Glass, being a super-cooled liquid, "dripped" down to the bottom over the many decades. The home was raized 18 months later.
