AATCC 147-1998 Antibacterial Activity Assessment of Textile Materials: Parallel Streak Method.
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 inclusive. 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 recommendations. 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. Department of Health and Human services publication Biosafety in Microbiological and Biomedical Laboratories should be con- sulted (see 13.1).
4.2 CAUTION: Some of the bacteria used in this test are pathogenic; i.e., capa- ble of infecting humans and producing disease. Therefore, every necessary and reasonable precaution must be taken to eliminate this risk to the laboratory per- sonnel and to personnel in the associated environment. Wear protective clothing and respiratory protection that prevents penetration by the bacteria.
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 Administrations [OSHA] permissible exposure limits [PEL] as found in 29 CFR 1910.1000 of January 1, 1989). In addi- tion, the American Conference of Gov- ernmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLVs) com- prised 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 13.2).
5. Uses and Limitations
5.1 The method is not suitable for ma- terials which tend to encapsulate and pre- vent the diffusion of the antibacterial agent or contain antibacterial-neutralizing substances.AATCC 147 pdf download.
