Asbestos is a naturally occurring fibrous mineral with documented uses dating back over 4000 years. Chrysotile is the most commonly encountered type of asbestos, accounting for up to 90% of asbestos products. Other forms of asbestos include amosite, crocidolite, tremolite, actinolite and anthophyllite.

The physical properties of asbestos, namely its incombustibility, high tensile strength, flexibility, insulating ability, resistance to chemicals and bacteria and its ability to control condensation, have resulted in asbestos being used in over 3000 different products.

Asbestos products generally fall into one of two forms, friable and nonfriable. Friable asbestos refers to a material that can be reduced to a powder by hand pressure. Nonfriable asbestos cannot be reduced to a powder by hand pressure. Friable forms of asbestos represent a greater hazard potential than nonfriable forms.

Friable asbestos products have, for the most part, been banned but some nonfriable products are still produced and are available in the United States.

In most instances, microscopic analysis is the only definitive method for determining whether or not a product contains asbestos.

Asbestos containing materials that are undisturbed and in good condition are considered non-hazardous. Once asbestos is disturbed by either manual methods or through the process of physical deterioration, the risk of asbestos exposure increases. Dust containing microscopic asbestos fibers can become airborne which increases the chance that these fibers can be inhaled or ingested.

It is important to remember that asbestos can only be removed or modified under controlled conditions and by a licensed asbestos abatement contractor or by specially trained University workers.

Never cut, drill, hammer, saw, scrape, break or move any asbestos containing material.

Asbestos has the potential to cause several different respiratory diseases and cancers. One unique aspect of asbestos related diseases is that the symptoms will not appear for 15 to 30 years following asbestos exposure.

Diseases typically associated with asbestos exposure include:

• Asbestosis
  • Involves scarring of the lungs and the gradual decrease in the ability to breathe and for the body to take in enough oxygen to sustain normal functions
• Lung Cancer
  • Involves the development of a malignant tumor of the bronchi covering within the lungs
  • Smokers who are also exposed to asbestos are at 80 to 90 times greater risk of developing lung cancer than individuals who work with asbestos but don’t smoke
• Mesothelioma
  • Refers to a cancer of the lining of the chest cavity or abdominal wall
  • This type of cancer has a very poor survival rate
  • Asbestos exposure is believed to be the only cause of mesothelioma

Asbestos exposure has also been implicated as a risk factor for the development of cancers of the larynx, esophagus and gastro-intestinal tract.

Factors that determine an individual’s chance of developing an asbestos related disease include:

• The amount and duration of asbestos exposure
• Whether or not an individual smokes
• The individuals age when the asbestos exposure occurred

Asbestos can be found in numerous building related materials at the University. The most commonly encountered asbestos containing materials include:

• Floor tile (most 9 inch, some 12 inch and older linoleum)
• Floor tile adhesive (usually black in color)
• Sprayed on fireproofing (typically above ceilings except in limited access maintenance areas)
• Pipe insulation (including hard mastic coatings)
• Roofing materials
• Laboratory fume hoods and Laboratory table and counter tops
• Cementitious asbestos panels in windows, doors and as fire stops

The noted items represent only a partial list of some of the asbestos products that may be encountered at UF.

The Environmental Health and Safety office should be contacted whenever there is a question concerning whether or not some material contains asbestos.

Generally speaking, buildings constructed after 1980 should not contain friable asbestos building materials though nonfriable asbestos products may still be present.

Notification signs are posted at the entrances to buildings known to contain asbestos containing materials. Additional warning signs are also posted at the entrances to maintenance and mechanical spaces containing asbestos.

Questions related to the presence of asbestos in University buildings should be directed to the Environmental Health and Safety office (352-392-1591)

The University of Florida follows EPA’s recommendations for managing asbestos in place. Elements of the asbestos management program include:

• Conducting periodic inspections of identified asbestos to document its condition
• Requiring updated asbestos surveys prior to any renovation or demolition project
• Requiring removal of asbestos containing materials only if the condition has deteriorated to the point of becoming hazardous or if the material will be impacted by work scheduled in its vicinity
• Requiring annual asbestos awareness training for all employees with maintenance or custodial responsibilities who have the potential to come into contact with asbestos containing materials.

The following asbestos related regulations apply to asbestos activities at the University of Florida:

• OSHA Asbestos Construction Standard (29 CFR 1926.1101
• OSHA Asbestos General Industry Standard (29 CFR 1910.1001)
• EPA NESHAP Asbestos Standard
• Florida Statute 469 and 255

The agency generally responsible for the enforcement of asbestos regulations at the University is the Florida Department of Environmental Protection.

The Environmental Health and Safety office is responsible for the administration of the University’s asbestos management program.
