PRECAUTIONARY MEASURES AND FIRST AID:

HANDLE IN ACCORDANCE WITH GOOD INDUSTRIAL HYGIENE AND SAFETY PRACTICES. THESE PRACTICES INCLUDE AVOIDING UNNECESSARY EXPOSURE AND REMOVAL OF THE MATERIAL FROM EYES, SKIN, AND CLOTHING.

OCCUPATIONAL CONTROL PROCEDURES:

Eye Protection: Silverlon® silver-coated nylon fabric does not cause significant eye irritation or eye toxicity requiring special protection. Use good industrial practice to avoid eye contact.
Skin Protection: Silverlon® silver-coated nylon fabric does not present a significant skin concern requiring special protection. Use good industrial hygiene practice.
Respiratory Protection: Avoid breathing dust. Use NIOSH/MSHA approved respiratory protection equipment when airborne exposure limits (see below) are exceeded. Consult respirator manufacturer to determine appropriate type equipment for given application. Observe respirator use limitations specified by NIOSH/MSHA or the manufacturer. Respiratory protection programs must comply with 29 CFR 1910.134.
Ventilation: Provide natural or mechanical ventilation to control exposure levels below airborne limits (see below). If practical, use local mechanical exhaust ventilation at sources of air contamination such as open process equipment. Consult NFPA Standard 91 for design of exhaust systems.

Airborne Exposure Limits:

Silver – Above melt point fumes of silver oxide may occur.
Hazardous Polymerization: does not occur.
HEALTH EFFECTS SUMMARY:

Effects of Exposure:
Silverlon® silver-coated nylon fabric consists of a woven nylon fiber substrate with a metallic surface coating. Skin contact is expected to be the primary route of occupational exposure to Silverlon® silver-coated nylon fabrics. Occupational exposure to this material has not been reported to cause significant adverse health effects. Due to its chemical and physical properties, Silverlon® silver-coated nylon fabrics do not appear to possess any toxicological properties which would require special handling other than good industrial hygiene and safety practices employed with any material of this type. Silverlon® coated nylon fabrics are not expected to present an inhalation hazard during routine shipping or handling. Under aggressive conditions of physical manipulation (carding, weaving, etc.), there is a potential for generation of respirable fibers and metal dusts. If respirable metal dusts are generated, see “Toxicological Data” below for potential toxic effects of silver and copper.

TOXICOLOGICAL DATA:

For potential health effects of exposure to any metal dusts generated under aggressive use conditions of silver nylon fabric, a summary of effects reported in the scientific literature on silver, the metal present in this metal coated material, as discussed below:

Silver: Excessive absorption and accumulation of silver in the body can cause argyria, a cosmetic change (bluish-gray discoloration of the skin, mucous membranes and eyes). Localized argyria may be due to penetration of the skin by particles of metallic silver. Generalized argyria may follow prolonged inhalation of silver dusts or swallowing of silver salts. Placement of silver foil and silver discs under the skin of rats have produced local tumors.
Additional Information:
Threshold Limit Values (TLVs) has been established by the American Conference of Governmental Industrial Hygienists for silver. For further information on these materials, please refer to the current edition of the Documentation of the Threshold Limit Values and Biological Exposure Indices.

PHYSICAL DATA:
Appearance: A solid coated fabric
Odor: None

SPILL, LEAK & DISPOAL INFORMATION:

Waste Disposal: Silverlon® silver coated nylon fabric is not a “hazardous waste” as that term is defined in 40 CFR 261. “Identification and Listing of Hazardous Waste.” Dispose of waste by recovery of metals, incineration, sanitary landfill, or other method in accordance with all applicable local, state and federal laws and regulations. Silver is listed in the “National Recovery and Resource Act.” Consult your attorney or appropriate regulatory officials for information on such disposal.

Spill or Leakage procedures: sweep up and place into containers for disposal as appropriate.
