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. Manufac- turers 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 Good laboratory practices should be followed. Wear safety glasses in all laboratory areas and a single use dust res- pirator while handling powder dyes.
4.2 All chemicals should be handled with care. The compounds used in this test method at the concentrations speci- fied are considered to present no signifi- cant hazard when used in accordance with good laboratory practices.
4.3 If concentrated acetic acid is di- luted to prepare the 10% acetic acid, use chemical goggles or face shield, impervi- ous gloves and an impervious apron dur- ing preparation. Concentrated acids should be handled only in an adequately ventilated laboratory hood. CAUTION: Always add acid to water.
4.4 An eyewash/safety shower should be located nearby and an organic vapor respirator with full facepiece should be readily available for emergency use.
4.5 Exposure to chemicals used in this procedure must be controlled at or below levels set by governmental authorities (e.g., Occupational Safety and Health Administrator’s [OSHA] permissible ex- posure 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 ex- posure which should be met (see 10.15).AATCC 146 pdf download.
