3. PRECAUTIONS FOR USE
3.1 Exposure Standards
The following Exposure Standards have been established by Worksafe : Phenol : TWA 5 ppm [19 mg/m3] ; can be absorbed through the skin Cresol, all isomers : TWA 5 ppm [22 mg/m3] ; can be absorbed through the skin
3.2 Engineering Controls
Use adequate ventilation to control exposure to below recommended levels.
3.3 Personal Protection
Respiratory - use NIOSH/MSHA approved air purifying respirator equipped with organic vapour cartridge(s) when concentrations exceed recommended exposure levels. Eyes - wear chemical safety goggles and a full face shield to protect against splashing. Skin - wear chemical resistant gloves when handling this material. Heavy PVC or butyl-viton is recommended. Other - impervious protective clothing and chemically resistant footwear.
3.4 Flammability
