DIBUTYL PHTHALATE
CASRN: 84-74-2
Hazards Summary :
The major hazards encountered in the use and
handling of dibutyl phthalate stem from its toxicologic
properties. Toxic by all routes (ie, inhalation, ingestion, dermal contact),
exposure to this colorless-to-yellow, oily liquid may occur from its use as a
plasticizer or solvent in lacquers, elastomers, chlorinated rubbers, polyvinyl
acetate, explosives, nail polish, perfumes, resins, printing
inks, paper coatings,
and adhesives. Effects from exposure may include contact burns to the skin and
eyes, dermatitis, nausea, and dizziness. Both the OSHA PEL and the ACGIH TLV
have been set at 5 mg/cu m. Odor thresholds have been found as low as 0.26 mg/cu
m. Ventilation should be used to maintain acceptable levels. In activities where
over-exposure may occur, wear a self-contained breathing apparatus and
protective clothing. If contact should occur, immediately flush affected skin
and eyes with running water for at least 15 minutes. While dibutyl
phthalate does not ignite easily, it may burn with the production of
irritating or poisonous gases. Fires involving dibutyl
phthalate may be extinguished with dry chemical, CO2, or Halon. Standard
foam or water fog, if used, should be applied with caution, as each may cause
violent frothing. Dibutyl phthalate may be shipped via
air, rail, road, and water. If small amounts of dibutyl
phthalate should spill, take up with sand or other noncombustible
absorbent and place into containers for later disposal. For large spills, first
dike far ahead of the area with soil, sand bags, foamed polyurethane, or foamed
concrete, then absorb bulk material with fly ash or cement powder. For large
spills in bodies of water, first use natural barriers or oil spill control booms
to limit spill motion, then apply detergent, soap, or alcohols to thicken
material. Apply "universal" gelling agent and remove trapped material
with suction hoses. If dissolved, apply activated charcoal, and use mechanical
dredges or lifts to remove immobilized masses. Before implementing land disposal
of waste dibutyl phthalate, consult with environmental
regulatory agencies for guidance. Also, dibutyl phthalate is
a good candidate for liquid injection, rotary kiln, and fluidized bed forms of
incineration.
