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.
Specification:
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.

Biomedical Effects and Toxicity
Pharmacological Action:
- Substances that increase the risk of NEOPLASMS in humans or animals. Both genotoxic chemicals, which affect DNA directly, and nongenotoxic chemicals, which induce neoplasms by other mechanism, are included.
Biomedical Effects and Toxicity:
THERE WERE SPECIES DIFFERENCES IN EXCRETION OF AN IP DOSE OF (14)C FLUORENE. GUINEA PIGS ELIMINATED (14)C MORE RAPIDLY THAN RATS OR RABBITS & AFTER 12 HR, HAD EXCRETED 53% IN URINE WHEREAS OTHER SPECIES HAD EXCRETED 12% & 20% RESPECTIVELY. IN 48 HR, IN URINE & FECES RESPECTIVELY, GUINEA PIGS EXCRETED 82% & 6%, RATS EXCRETED 57% & 16% & RABBITS EXCRETED 39% & 1%. 24 HR AFTER DOSE TO RATS, INTESTINAL TRACT CONTAINED 14% OF THE (14)C & SINCE THIS HAD NOT ALTERED 24 HR LATER, ENTERO-HEPATIC CIRCULATION OF FLUORENE &/OR ITS METABOLITES MAY HAVE OCCURRED TO MAINTAIN THOSE LEVELS. HOWEVER, SLOW RELEASE OF 14(C) FROM INJECTION SITE PROVIDES AN ALTERNATIVE EXPLANATION.
Environmental Fate and Exposure Potential
Environmental Fate/Exposure Summary:
Polycyclic aromatic hydrocarbons with 4 or less aromatic rings are degraded by microbes and are readily metabolized by multicellular organisms; biodegradation may be the ultimate fate process. /Polycyclic aromatic hydrocarbons/
Biodegradation is probably slower in the aquatic system than in the soil, and biodegradation may be much more important in those aquatic systems which are chronically affected by contamination. /Polycyclic aromatic hydrocarbons/
In microbial degradation studies conducted in sandy material, fluorene and other PAHs 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).
In biodegradation tests using groundwater from a moderately contaminated well, fluorene degraded at a rate of 33-54% per week under conditions of dissolved oxygen addition and/or nutrient addition(1); no degradation occurred in sterile controls or in tests where limited oxygen was available(1). In a pilot-plant experimental system (simulating a waste treatment facility), 34-39% of influent fluorene was removed via biodegradation (the remainder was removed via strip loss (5-10%) and adsorption to sludge)(2). In a shake-flask screening study using creosote-contaminated soil as inoculum, 99% of initial fluorene was degraded after a 14 day incubation period(3); in sterile controls, only 15% of initial fluorene was lost(3). In river die-away tests using two natural river waters, little or no fluorene was degraded to CO2 (14-CO2 radio-labelled measurement) over a 24 hr incubation period(4).
