OTHER EFFECTS OF OVEREXPOSURE:
Overexposure to vapor generated at high temperatures may
result in eye and respiratory tract irritation, dizziness,
nausea and the inhalation of harmful amounts of material.

Medial Conditions Aggravated By Exposure

A knowledge of available toxicology information and of the
physical and chemical properties of the material suggests that
overexposure is unlikely to aggravate existing medical
conditions.

FOR INDUSTRY USE ONLY.

This product may contain trace amounts of ethylene oxide
(CAS No 75-21-8), a condition which creates the potential
for accumulation of ethylene oxide in the head space of
shipping and storage containers and in enclosed areas where
the product is being handled or used. Ethylene oxide is
listed by OSHA as probably carcinogenic to humans, IARC as
carcinogenic to humans, and NTP as reasonably anticipated to
be carcinogenic. OSHA considers that, at excessive levels,
ethylene oxide may present reproductive, mutagenic,
genotoxic, neurologic and sensitization hazards. If the
product is handled with adequate ventilation, the presence
of these trace amounts is not expected to result in any
short or long term hazard.

This product may not be exempt from OSHA'S ethylene oxide
standard, 29CFR1910.1047. Users should comply with all
applicable provisions. Personnel should be monitored to
determine levels of exposure to ethylene oxide. If
necessary, protective measures should be taken. The OSHA
permissible exposure limit for ethylene oxide is 1 ppm TWA8,
the action level is 0.5 ppm TWA8, the ACGIH TLV is 1 ppm
TWA8 and OSHA has established an excursion limit of 5 ppm
(15 minute average).

VENTILATION:
General (mechanical) room ventilation is expected to be
satisfactory.

STORAGE:
No information currently available.

RESPIRATORY PROTECTION: None expected to be needed.

VENTILATION:
General (mechanical) room ventilation is expected to be
satisfactory.

EYE PROTECTION: Safety glasses or monogoggles

OTHER PROTECTIVE EQUIPMENT: Eye bath, Safety shower.

ENGINEERING CONTROLS

PROCESS HAZARD:
Sudden release of hot organic chemical vapors or mists from
process equipment operating at elevated temperature and pressure,
or sudden ingress of air into hot equipment under a vacuum, may
result in ignitions without the presence of obvious ignition
sources. Published "autoignition" or "ignition" temperature
values cannot be treated as safe operating temperatures in
chemical processes without analysis of the actual process
conditions. Any use of this product in elevated-temperature
processes should be thoroughly evaluated to establish and
maintain safe operating conditions.

SIGNIFICANT DATA WITH POSSIBLE RELEVANCE TO HUMANS
A chronic dietary feeding study of diethylene glycol with rats
showed mild kidney injury at 1% while concentrations of 2% and 4%
caused more marked kidney injury. In addition, at 2% and 4% of
diethylene glycol in the diet, some rats developed benign
papillary tumors in the urinary bladder. These have been
attributed to the presence of urinary bladder calcium oxalate
stones. No evidence of carcinogenicity was found with a chronic
skin-painting study with diethylene glycol in mice. The absence
of a direct chemical carcinogenic effect accords with the results
in-vitro genotoxicity studies which show that it does not
produce mutagenic or clastogenic effects. A feeding study
employing up to 5.0% diethylene glycol in the diet failed to
produce any teratogentic effects. In a mouse continuous breeding
study with large doses of diethylene glycol in drinking water,
there was evidence for reproductive toxicity at 3.5% (equivalent
to 6.1 g/kg/day) as reduced numbers of litters, live pups per
litter, and live pup weight. No such effects were seen at 1.75%
(approximately 3.05 g/kg/day). The relevance of these very high
dosages to human health is uncertain. Pregnant rats receiving
undiluted diethylene glycol by gavage over the period of
organogenesis had toxic effects at 4.0 and 8.0 ml/kg/day as
mortality, decreased body weight, decreased food consumption,
increased water consumption, and increased liver and kidney
weights. Fetotoxicity was seen only at these maternally toxic
dosages. Decreased fetal body weight occurred at 8.0 ml/kg/day,
and increased skelatal variants at 4.0 and 8.0 ml/kg/day. No
embryotoxic or teratogenic effects were seen. Neither maternal
toxicity nor fetotoxicity occurred at 1.0 ml/kg/day. In a study
with mice also receiving undiluted diethylene glycol over the
period of organogenesis, maternal toxicity occurred at 2.5 and
10.0 ml/kg/day, but not at 0.5 ml/kg/day. Definitive
developmental toxicity was not seen in this species.

ADDITIONAL STUDIES:
Although this material is not a skin irritant, submersion by
workers of unprotected skin in highly concentrated solutions of
this material for prolonged periods of time could result in skin
dehydration.
