Grade: Technical
Exposure Standards and Regulations
Tributyl phosphate is an indirect food additive for use only as a component of adhesives.
Reactivities and Incompatibilities
Alkalis, oxidizers, water, moist air.
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 order to handle industrial and commercial organic phosphites and phosphates, a careful evaluation should be undertaken to determine the precise effects of the individual phosphorus compound involved. Usually, all skin contact and inhalation of vapors or dusts should be avoided. All persons handling such materials should undergo regular medical examinations, with special stress on the central nervous system. /Esters of Organic Phosphorus Compounds/
Work clothing that becomes wet or significantly contaminated should be removed and replaced.
The worker should immediately wash skin when it become contaminated.
Avoidance of skin contact & inhalation of mist, dust, or vapor (esp if heated liq are handled) will usually be desirable... /Contaminated clothing removed & skin washed/. /Phosphate esters/
Being toxic, protect body against skin contact and inhalation.
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
Protective Equipment and Clothing
Wear appropriate personnel protective clothing to prevent skin contact.
Wear appropriate eye protection to prevent eye contact.
Respirator Recommendations: Up to 2 ppm: (Assigned Protection Factor = 10) Any supplied-air respirator.
Respirator Recommendations: Up to 5 ppm: (Assigned Protection Factor = 25) Any supplied-air respirator operated in a continuous-flow mode.
Respirator Recommendations: Up to 10 ppm: (Assigned Protection Factor = 50) Any self-contained breathing apparatus with a full facepiece./(Assigned Protection Factor = 50) Any supplied-air respirator with a full facepiece.
Respirator Recommendations: Up to 30 ppm: (Assigned Protection Factor = 2000) Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode.
Respirator Recommendations: Emergency or planned entry into unknown concentrations or IDLH conditions: (Assigned Protection Factor = 10,000) Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode./(Assigned Protection Factor = 10,000) Any supplied-air respirator that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained positive-pressure breathing apparatus.
Respirator Recommendations: Escape: (Assigned Protection Factor = 50) Any air-purifying, full-facepiece respirator (gas mask) with a chin-style, front- or back-mounted organic vapor canister having an N100, R100, or P100 filter./Any appropriate escape-type, self-contained breathing apparatus.
Specification

? Tributyl phosphate , with CAS number of 126-73-8, can be called Tributilfosfato ; Celluphos 4 ; Butyl phosphate, tri- ; 1-dibutoxyphosphoryloxybutane ; Butyl phosphate ; Phosphoric acid tributyl ester ; tributyl ester ; Tributoxyphosphine oxide ; TBP Tributyl phosphate ; Tributyl phosphate (TBP)?. Tributyl phosphate (CAS NO.126-73-8) , known commonly as TBP, is a solvent and plasticizer for cellulose esters such as nitrocellulose and cellulose acetate. The major uses of TBP in industry are as a component of aircraft hydraulic fluid and as a solvent for extraction and purification of rare earth metals from their ores. Tributyl phosphate is used also in mercerizing liquids, where it improves their wetting properties. Tributyl phosphate is also used as a heat exchange medium. TBP is used in some consumer products such as herbicides and water thinned paints and tinting bases.

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.
