AATCC 174-2016 Test Method for Antimicrobial Activity Assessment of New Carpets. 4. Safety Precautions NOTE: These safety precautions are for information purposes only. The pre- cautions are ancillary to the testing proce- dures and are not intended to be all inclu- sive. It is the user’s responsibility to use safe and proper techniques in handling materials in this test method. Manufacturers MUST be consulted for specific details such as material safety data sheets and other manufacturer’s recommenda- tions. All OSHA standards and rules must also be consulted and followed. 4.1 This test should be performed only by trained personnel. The U.S. Depart- ment of Health and Human Services pub- lication Biosafety in Microbiological and Biomedical Laboratories should be con- sulted (see 25.1). 4.2 CAUTION: Some of the microorganisms used in these tests are allergenic and pathogenic; i.e., capable of infecting humans and producing disease. Therefore, every necessary and reasonable pre- caution must be taken to eliminate this risk to the laboratory personnel and to personnel in the associated environment. Wear protective clothing, respiratory protection, and impervious gloves when working with the organisms. Choose res- piratory protection that prevents penetra- tion by the spores. 4.3 Good laboratory practices should be followed. Wear safety glasses in all laboratory areas. 4.4 All chemicals should be handled with care. 4.5 An eyewash/safety shower should be located nearby for emergency use. 4.6 Sterilize all contaminated samples and test materials prior to disposal. 4.7 Exposure to chemicals used in this procedure must be controlled at or below levels set by government authorities (e.g., Occupational Safety and Health Admin- istration’s [OSHA] permissible exposure limits [PEL] as found in 29 CFR 1910.1000 (see web site: www.osha.gov for latest version). In addition, the Ameri- can Conference of Governmental Indus- trial Hygienists (ACGIH) Threshold Limit Values (TLVs) comprised of time weighted averages (TLV-TWA), short term exposure limits (TLV-STEL) and ceiling limits (TLV-C) are recommended as a general guide for air contaminant exposure which should be met (see 25.2). 5. Uses and Limitations 5.1 This test method is designed for use only for new carpets and must not be used for carpets that have been laid down and used.AATCC 174 pdf download.
