Other Preventative Measures
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Personal Protection:
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Fire Fighting: Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Use agent most appropriate to extinguish fire.

  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: In microbial degradation studies conducted in sandy material, fluorene and other polyaromatic hydrocarbons degraded to an average of 80%(1); in sterile controls, fluorene did not degrade suggesting microbial activity as the route of degradation(1). A review of environmental fate for fluorene has reported a fluorene biotransformation rate constant of 0.0062-0.01/hr(2); this corresponds to a half-life of 2.9-4.6 days(SRC). In a 7 day static incubation study using a sewage seed (followed by three weekly subculture inoculations for a total of 28 days of incubation), 65-82% of initial fluorene (5 and 10 ppm) was degraded after 7 days and 45-77% (of total additions) was degraded after 28 days(3); fluorene was classified as significantly degraded with gradual microbial adaptation(3). In biodegradation screening studies using subsurface soil from a contaminated creosote site, >92% of initial fluorene degraded within 1 week of incubation(4); in autoclaved soil, the degradation rate fell to 3.4% per week(4); using soil from a pristine site, the degradation rate was not statistically different between autoclaved and non-autoclaved soil suggesting that microbial adaptation to fluorene is important in subsurface regions(4).

12.3 Bioaccumulative potential

A log BCF of 3.17 (1479) was measured in the fathead minnow (Pimephales promelas) which were exposed over 28 days in a flow-through system(1). Log BCFs of 3.02-3.35 (1047-2238) were measured in guppies (Poecilia reticulata) exposed in 2-4 day periods under static and semi-static test conditions(2). A log BCF of 3.15 (1412) was measured in mosquitofish (Gambusia affinis) exposed over a 33 day exposure using an aquatic ecosystem(3). According to a classification scheme(4), these BCF values suggest the potential for bioconcentration in aquatic organisms is very high(SRC), provided the compound is not metabolized by the organism(SRC). Bioconcentration studies on compounds which are structurally similar suggest that bioconcentration may be lower than that indicated by the regression-derived equations due to the ability of aquatic organisms to readily metabolize this class of compounds(5).

12.4 Mobility in soil

Log Koc values of 3.70 to 4.21 (5011 to 16,218) have been measured for fluorene using aquifer materials and humic materials occurring in natural water and soil(1-3). According to a classification scheme(4), these Koc values suggest that fluorene is expected to be immobile in soil. Log Koc values of 6.52 and 6.45 were reported using sediment from Lake Ketelmeer, The Netherlands(5). In an adsorption study using an estuarine water, 12% of added fluorene was adsorbed by particulate matter in water (organic matter, bacteria, clay particles, etc) over a 3-hour period which indicates that adsorption in natural estuarine water is an important environmental fate process(6).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods


The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
