Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. /Xylenols; Xylenols, liquid; Xylenols, solid/
/GUIDE 153: SUBSTANCES - TOXIC AND/OR CORROSIVE (COMBUSTIBLE)/ Fire or Explosion: Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. Those substances designated with a "P" may polymerize explosively when heated or involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. /Xylenols; Xylenols, liquid; Xylenols, solid/
/GUIDE 153: SUBSTANCES - TOXIC AND/OR CORROSIVE (COMBUSTIBLE)/ Public Safety: CALL Emergency Response Telephone Number ... . As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate enclosed areas. /Xylenols; Xylenols, liquid; Xylenols, solid/
/GUIDE 153: SUBSTANCES - TOXIC AND/OR CORROSIVE (COMBUSTIBLE)/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible. /Xylenols; Xylenols, liquid; Xylenols, solid/
/GUIDE 153: SUBSTANCES - TOXIC AND/OR CORROSIVE (COMBUSTIBLE)/ Evacuation: ... Fire: If tank, rail car or tank truck is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. /Xylenols; Xylenols, liquid; Xylenols, solid/
/GUIDE 153: SUBSTANCES - TOXIC AND/OR CORROSIVE (COMBUSTIBLE)/ Fire: Small fires: Dry chemical, CO2 or water spray. Large fires: Dry chemical, CO2, alcohol-resistant foam or water spray. Move containers from fire area if you can do it without risk. Dike fire control water for later disposal; do not scatter the material. Fire involving tanks or car/trailer loads: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Do not get water inside containers. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. /Xylenols; Xylenols, liquid; Xylenols, solid/
/GUIDE 153: SUBSTANCES - TOXIC AND/OR CORROSIVE (COMBUSTIBLE)/ Spill or Leak: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS. /Xylenols; Xylenols, liquid; Xylenols, solid/
/GUIDE 153: SUBSTANCES - TOXIC AND/OR CORROSIVE (COMBUSTIBLE)/ First Aid: Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. /Xylenols; Xylenols, liquid; Xylenols, solid/
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.
Protective Equipment and Clothing:
Some data suggesting breakthrough times /for butyl rubber/ of approximately an hour or more. /Aromatic hydroxyl cmpd/
Breakthrough times /for neoprene/ greater than one hour reported by (normally) two or more testers. /Aromatic hydroxyl cmpd/
Breakthrough times /for polyvinyl alcohol/ less (usually significantly less) than one hour reported by (normally) two or more testers. /Aromatic hydroxyl cmpd/

Environmental Fate and Exposure Potential
Environmental Fate/Exposure Summary:
TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 460(SRC), determined from a log Kow of 2.36(2) and a regression-derived equation(3), indicates that 2,6-dimethylphenol is expected to have moderate mobility in soil(SRC). Volatilization of 2,6-dimethylphenol from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 6.7X10-6 atm-cu m/mole (4). 2,6-Dimethylphenol is not expected to volatilize from dry soil surfaces(3) based upon a vapor pressure of 0.274 mm Hg at 25 deg C(4). The rate of biodegradation obtained for 2,6-dimethylphenol in a screening test with an adapted activated sludge seed was 94.3% chemical oxygen demand after 5 days(6). Other dimethylphenols have been reported to degrade within 4 to 14 days from soil(7).
AQUATIC FATE: Based on a classification scheme(1), a Koc value of 460(SRC), determined from a log Kow of 2.36(2) and a regression-derived equation(3), indicates that 2,6-dimethylphenol is expected to adsorb very little to suspended solids and sediment in water(SRC). 2,6-Dimethylphenol is expected to volatilize from water surfaces(3,SRC) based upon a Henry's Law constant of 6.7X10-6 atm-cu m/mole(4). Estimated volatilization half-lives for a model river and model lake are 6 days and 49 days, respectively(3,SRC). According to a classification scheme(5), an estimated BCF of 37(3,SRC), from 2,6-dimethylphenol's log Kow(2), suggests bioconcentration in aquatic organisms is moderate(SRC). In humic waters, degradation by the reaction with peroxy radicals should ensue with a half-life on the order of hours(6). 2,6-Dimethylphenol is not expected to undergo hydrolysis in the environment due to the lack of hydrolyzable functional groups(3). Screening studies indicate that a loss of 94.3% chemical oxygen demand was obtained after 5 days(7). In addition, it has been reported that 2,6-dimethylphenol was readily degraded in St. Lawrence River water(8). Biodegradation under anaerobic conditions failed to occur in one study, time unspecified(9) and only 7% degradation occurred after 8 weeks in another study(10).
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2,6-dimethylphenol, which has a vapor pressure of 0.274 mm Hg at 25 deg C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase 2,6-dimethylphenol is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 5.8 hours(SRC) from its rate constant of 6.60X10-11 cu cm/molecule-sec at 25 deg C(3). Atmospheric 2,6-dimethylphenol is known to be removed by rainwater(4). 2,6-Dimethylphenol has an absorption band at 268 nm (water), and a shoulder may extend over 290 nm, thus making it a candidate for direct photochemical degradation(5,6). Night-time degradation in urban areas should occur rapidly through reaction with atmospheric nitrate radicals, as rate constants for this reaction with phenolic compounds are approximately 250 times faster than with hydroxyl radicals(7,SRC).
