5. ENVIRONMENTAL AND DISPOSAL INFORMATION
---------------------------------------------------------------------------
ENVIRONMENTAL DATA: This pesticide is toxic to fish. For terrestrial uses,
do not apply directly to water, or to areas where surface water is present
or to intertidal areas below the mean high water mark. Drift or runoff
from treatment areas may be hazardous to aquatic organisms in neighboring
aquatic sites. Do not contaminate water when disposing of equipment
washwaters or rinsate.
ACTION TO TAKE FOR SPILLS: Use absorbent materials to contain and clean up
small spills and dispose as waste. Large spills report to CHEMTREC and
DowElanco for assistance. Prohibit use of hot or sparking equipment in
immediate area. Prevent runoff.
DISPOSAL METHOD: Do not contaminate water, food or feed by storage or
disposal. Waste resulting from formulation of this product may be disposed
of on site or at an approved waste disposal facility. Follow all local,
state, and Federal requirements for disposal.
---------------------------------------------------------------------------
6. HEALTH HAZARD DATA
---------------------------------------------------------------------------
EYE: May cause moderate irritation with corneal injury; in test animals,
effects healed in 1-14 days. Solvent vapors may irritate eyes.
SKIN CONTACT: Prolonged or repeated exposure may cause skin irritation,
even a burn. May cause allergic skin reaction in susceptible individuals.
Solvent may cause drying or flaking of skin.
SKIN ABSORPTION: A single prolonged exposure is not likely to result in the
material being absorbed through skin in harmful amounts. The LD50 for skin
absorption in rabbits is >2000 mg/kg.
INGESTION: Single dose oral toxicity is low. The oral LD50 for rats is
greater than 2900 mg/kg. Small amounts swallowed incidental to normal
handling operations are not likely to cause injury; swallowing amounts
larger than that may cause injury. If aspirated (liquid enters the lung),
may cause lung damage or even death due to chemical pneumonia.
INHALATION: Based on data obtained on solvent, excessive vapor
concentrations (of solvent components) are attainable and could be
hazardous on single exposure; excessive exposure may cause irritation of
the eyes, upper respiratory tract, and lungs. Signs and symptoms of
excessive exposure may be central nervous system effects.
SYSTEMIC (OTHER TARGET ORGAN) EFFECTS: Excessive exposure may cause liver,
kidney, lung and blood effects. Xylene is reported to have caused hearing
loss in laboratory animals upon exposure to high concentrations; such
effects have not been reported in humans. One component (naphthalene) has
been associated with cataracts and other eye effects from vapors or dust.
CANCER INFORMATION: Solvent did not cause cancer in long-term animal
studies. Xylene in solvent was not found to be carcinogenic in a National
Toxicology Program bioassay in rats and mice. The active ingredient
(trifluralin) was associated with a low incidence of urinary tract tumors
in one strain of rat in 1 of 5 chronic (2 yr) studies conducted, and is not
anticipated to be a carcinogenic risk to man. May contain a small amount of
naphthalene, which has caused cancer in some laboratory animals.
TERATOLOGY (BIRTH DEFECTS): Solvent contains a small amount of ethylbenzene
which has caused birth defects in laboratory animals. Exaggerated doses of
xylene (in solvent) given orally to pregnant mice resulted in an increase
in cleft palate, a common developmental abnormality in mice. Inhalation
exposure to xylene of pregnant animals resulted in toxicity to the fetus
but did not cause any birth defects.
REPRODUCTIVE EFFECTS: Data on ethylbenzene (a minor solvent component) are
inadequate to determine effects on reproduction. Other tested components
did not interfere with reproduction in animal studies.
MUTAGENICITY (EFFECTS ON GENETIC MATERIAL): Mutagenicity testing with
trifluralin has been negative in most in-vivo and in-vitro systems.
Positive results in a Drosophila m. study are contradicted by results in
in-vivo mammalian test systems.
---------------------------------------------------------------------------
7. FIRST AID
---------------------------------------------------------------------------
EYES: Hold eyelids open and flush with a steady, gentle stream of water for
15 minutes. See an opthalmologist or physician immediately.
SKIN: Immediately wash with plenty of soap and water. Get medical attention
if irritation develops.
INGESTION: Do not induce vomiting. Contains an aromatic hydrocarbon and
can be extremely harmful if swallowed. Call a physician or poison control
center. If available, administer activated charcoal (6 to 8 heaping
teaspoonfuls) with a large quantity of water. Do not induce vomiting or
give anything by mouth to an unconscious person. Immediately transport to a
medical care facility and see a physician.
INHALATION: Remove individual to fresh air. Get medical attention if
breathing difficulty occurs. If not breathing, provide cardiopulmonary
resuscitation assistance (mouth-to-mouth) and call a physician.
NOTE TO PHYSICIAN: This product contains an aromatic hydrocarbon and can be
extremely harmful if swallowed. Aspiration of this product may produce
a severe pneumonitis. Stomach lavage with a cuffed endotracheal tube in
place and immediate administration of activated charcoal, 6-8 heaping
teaspoonfuls with water, should be considered. Treatment is otherwise
symptomatic and supportive.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: No corroborative
information is available that would establish the aggravation of a medical
condition by exposure to TREFLAN; however, it is a reasonable assumption
that highly allergic individuals would be at a somewhat greater risk for
demonstrating an allergic reaction when exposed. Additionally, the xylene
content of TREFLAN E.C. could be a source of irritation for individuals
with sensitive skin. Inhalation of vapors could aggravate an underlying
lung or heart disorder. Effects of alcohol consumption may be increased by
significant exposure to xylene.
---------------------------------------------------------------------------
8. HANDLING PRECAUTIONS
---------------------------------------------------------------------------
EXPOSURE GUIDELINES: Xylene: ACGIH TLV and OSHA PEL are 100 ppm TWA, 150
PPM STEL. Ethylbenzene: ACGIH TLV and OSHA PEL are 100 ppm TWA, 125 ppm
STEL. Naphthalene: ACGIH TLV and OSHA PEL are 10 ppm TWA, 15 ppm STEL. PELs
are in accord with those recommended by OSHA, as in the 1989 revision of
PELs.
VENTILATION: Provide general and/or local exhaust ventilation to control
airborne levels below the exposure guidelines.
RESPIRATORY PROTECTION: Atmospheric levels should be maintained below
the exposure guidelines. When respiratory protection is necessary, use
an approved air-purifying or positive-pressure supplied air respirator
depending on the potential airborne concentration. For emergency and
other conditions where exposure guidelines may be greatly exceeded, use
an approved positive-pressure self-contained breathing apparatus or
positive-pressure airline with auxiliary self-contained air supply. In
confined or poorly ventilated areas, use an approved positive-pressure
supplied-air respirator.
SKIN PROTECTION: For handling prior to end-use of this product, use
protective clothing impervious to this material when prolonged or
frequently-repeated contact could occur. Selection of specific items such
as faceshield, gloves, boots, apron, or full-body suit will depend on
operation.
For handling relative to end-use of this product, the Worker Protection
Standard of 1993 requires that applicators and other handlers must wear
long-sleeved shirt and long pants; chemical-resistant gloves such as
Barrier Laminate or Viton; and shoes and socks. Users should remove
clothing immediately if pesticide gets inside. Then wash thoroughly and put
on clean clothing.
Discard clothing and other absorbent materials that have been drenched or
heavily contaminated with this product's concentrate. Do not reuse them.
Remove personal protective equipment (PPE) immediately after handling this
product. Wash the outside of gloves before removing. As soon as possible,
wash thoroughly and change into clean clothing.
Follow manufacturer's instructions for cleaning/maintaining PPE. If there
are no such instructions for washables, use detergent and hot water. Keep
and wash PPE separately from other laundry.
EYE PROTECTION: Use chemical goggles when handling concentrate. If vapor
exposure causes eye discomfort, use a full-face respirator. Applicators and
other handlers must wear protective eyewear.
