product has a high volume resistivity and a propensity to build up static
electricity which may be discharged as a spark. A spark can be an ignition
source for solvent, ensure appropriate safe handling practices such as
provision for inserting flammable vapors and measures as those cited above.
Extinguishing Media: Use water spray, dry chemical, or foam.
Carbon dioxide may be ineffective on larger fires due to lack of cooling
capacity which may result in resignation.
Fire Fighting Procedures: Avoid hose streams or any method which
will create dust clouds. Wear self-contained breathing apparatus (SCBA)
equipped with a full face piece and operated in a pressure-demand mode (or
other positive pressure mode) and approved protective clothing. Personnel
without suitable respiratory protection must leave the area to prevent
significant exposure to hazardous gases from combustion, burning or
decomposition. In an enclosed or poorly ventilated area, wear SCBA during
cleanup immediately after a fire as well as during the attack phase of
firefighting operations.
10. Toxicological Information
Acute Oral LD50: >2500 mg/kg (rat)
Note: These results are typical for this family of polymers.
Chronic Oral Toxicity: No significant effects in rats or dogs fed with
resin as 5% of diet for 6-1/2 months.
Dermal and Eye Irritation Test: Skin: no evidence of irritation or
sensitization during human patch testing.
General: No evidence of adverse effects from polyacrylate dust
exposure was observed in studies of workers. Neither lower airway
symptoms, chronic parenchymal disease, radiographic changes, nor clinically
important effects on lung function were found to result from polyacrylate
exposure. Only a small increase in upper respiratory symptoms appeared to
be related to exposure. However, various lung effects such as inflammation,
hyperplasia (abnormal increases in the number cells composing a tissue or
organ), scarring (fibrosis), changes in the air sac (alveolar) ducts of the lung,
and tumors were noted in laboratory studies with rodents inhaling
concentrations of a water sodium polyacrylate dust greater than 0.05 mg/m3
for the majority of their lives. Furthermore, some lung or lung cell effects
were found in rodent laboratory studies of shorter duration.
11. Disposal Considerations
For waste disposal purposes, this product is not known to be defined or
designated as hazardous by current provisions of the Federal (EPA) Resource
Conservation and Recovery Act (RCRA 40CFR261). Incinerate or landfill
waste in a properly permitted facility in accordance with federal, state and
local regulations. In appropriate dust/air ratio, dust cloud in air has explosion
potential. Therefore, land disposal must be in closed containers. If disposal is
in bulk form, recognize that this polymer absorbs moisture resulting in a
gelatinous mass that is unable to support human weight.
