Skin, Eye, and Respiratory Irritations:
May cause respiratory tract irritation. May be harmful if absorbed through skin. May cause skin irritation. May cause eye irritation.
Cleanup Methods:
Personal precautions: Use personal protective equipment. Avoid dust formation. Avoid breathing dust. Ensure adequate ventilation.
Environmental precautions: Do not let product enter drains.
Methods for cleaning up: Pick up and arrange disposal without creating dust. Keep in suitable, closed containers for disposal.
Transport:
225kgs
Fire Fighting Procedures:
Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Special protective equipment for fire-fighters: Wear self contained breathing apparatus for fire fighting if necessary.
Reactivities and Incompatibilities:
Materials to avoid: Bases, acid chlorides, acid anhydrides, oxidizing agents, brass, copper.
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.
In case of skin contact: Wash off with soap and plenty of water. Consult a physician.
In case of eye contact: Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
Handling: Avoid formation of dust and aerosols.
Hygiene measures: Handle in accordance with good industrial and safety practice. Wash hands before breaks and at the end of workday.
Protective Equipment and Clothing:
Personal protective equipment: Respiratory protection- Where risk assessment shows air-purifying respirators are appropriate use a dust mask type N95 (US) or type P1 (EN 143) respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Hand protection- Handle with gloves. For prolonged or repeated contact use protective gloves. Eye protection- Safety glasses.
Hand protection: Handle with gloves. For prolonged or repeated contact use protective gloves.
Eye protection: Safety glasses.
Skin and body protection: Choose body protection according to the amount and concentration of the dangerous substance at the work place.
Provide appropriate exhaust ventilation at places where dust is formed. Normal measures fro preventive fire protection.
Octanol/Water Partition Coefficient:
log Kow = 6.06
Disposal Methods:
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
Observe all federal, state, and local environmental regulations.
Use and Manufacturing
Use and Manufacturing:
U.S. Production

Production volumes for non-confidential chemicals reported under the Inventory Update Rule. Year Production Range (pounds) 1986 >1 million - 10 million 1990 >1 million - 10 million 1994 >1 million - 10 million 1998 >1 million - 10 million 2002 >10 million - 50 million
Production volumes for non-confidential chemicals reported under the Inventory Update Rule. Year Production Range (pounds) 2006 10 to <50 million
Phenol, 2,4,6-tris(1,1-dimethylethyl)- is listed as a High Production Volume (HPV) chemical (65FR81686). Chemicals listed as HPV were produced in or imported into the U.S. in >1 million pounds in 1990 and/or 1994. The HPV list is based on the 1990 Inventory Update Rule. (IUR) (40 CFR part 710 subpart B; 51FR21438).
Environmental Fate and Exposure Potential
Environmental Fate/Exposure Summary:
TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 63,000(SRC), determined from a log Kow of 6.06(2) and a regression-derived equation(3), indicates that 2,4,6-tris(1,1-dimethylethyl)phenol is expected to be immobile in soil(SRC). Volatilization of 2,4,6-tris(1,1-dimethylethyl)phenol from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 6.5X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 6.61X10-4 mm Hg(4), and water solubility, 35 mg/L(2). However, adsorption to soil is expected to attenuate volatilization(SRC). 2,4,6-Tris(1,1-methylethyl)phenol is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(4). Utilizing the Japanese MITI test, 0% of the theoretical BOD was reached in 4 weeks using an activated sludge(5), suggesting that biodegradation is not an important environmental fate process in soil(SRC).
AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 63,000(SRC), determined from a log Kow of 6.06(2) and a regression-derived equation(3), indicates that 2,4,6-tris(1,1-dimethylethyl)phenol is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 6.5X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 6.61X10-4 mm Hg(4), and water solubility, 35 mg/L(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 9 and 73 days, respectively(SRC). However, volatilization from water surfaces is expected to be attenuated by adsorption to suspended solids and sediment in the water column. The estimated volatilization half-life from a model pond is 440 years if adsorption is considered(5). According to a classification scheme(6), measured BCF values of 4830-16,000 and 4320-23,200 in carp (Cyprinus carpio) exposed to 10 and 1 ppb, respectively(7), suggest bioconcentration in aquatic organisms is very high(SRC). Utilizing the Japanese MITI test, 0% of the theoretical BOD was reached in 4 weeks using an activated sludge(7), suggesting that biodegradation is not an important environmental fate process in water(SRC).
ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), 2,4,6-tris(1,1-dimethylethyl)phenol, which has a vapor pressure of 6.61X10-4 mm Hg at 25 deg C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase 2,4,6-tris(1,1-dimethylethyl)phenol 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 24 hours(SRC), calculated from its rate constant of 1.6X10-11 cu cm/molecule-sec at 25 deg C(SRC) that was derived using a structure estimation method(3). Particulate-phase 2,4,6-tris(1,1-dimethylethyl)phenol may be removed from the air by wet or dry deposition(SRC). 2,4,6-Tris(1,1-dimethylethyl)phenol does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
