EPM-2463 PART A

SECTION 2: Hazards identification

EFFECTS OF SINGLE OVEREXPOSURE: SWALLOWING: No evidence of adverse effects from available information. SKIN ABSORPTION: No evidence of adverse effects from available information. INHALATION: No evidence of adverse effects from available information. SKIN CONTACT: Localized argyria (permanent bluish-gray discoloration) of the skin may occur from the handling of metallic silver or from particles becoming embedded in the skin. EYE CONTACT: May cause irritation, experienced as stinging, excess blinking and tear production, with excess redness and swelling of the conjunctiva. Contact with metallic silver has caused localized argyria of the conjunctiva. EFFECTS OF REPEATED OVEREXPOSURE: No injury from silica or dust should occur during reasonable use. If use creates respirable particles, some respiratory system injury may occur. However, since the silica, silver, and nickel in this product is compounded into the polymer matrix, it is not expected to present the same hazards as in their neat forms.

Medical Conditions Generally Aggravated by Exposure

OVEREXPOSURE Skin contact can cause an allergic skin rash and/or asthma in previously sensitized individuals. SIGNIFICANT LABORATORY DATA WITH POSSIBLE RELEVANCE TO HUMAN HEALTH HAZARD EVALUATION: The IARC and the NTP have classified elemental nickel as possibly carcinogenic to humans. However, since the nickel in this product is encapsulated within silver and within the polymer matrix, it is not expected, during reasonable use, to present the same hazards as in the neat form. The EPA has expressed concern regarding the possible adverse health effects resulting from the inhalation of alkoxysilanes and has recommended that administrative and mechanical means be used to minimize exposures. OTHER EFFECTS OF OVEREXPOSURE: None currently known.
