Therefore the air <br /> speed at the extraction point should be adjusted,accordingly,after reference to distance from the contaminating source. <br /> The air velocity at the extraction fan,for example,should be a minimum of 1-2 m/s(200-400 f/min.)for extraction of <br /> solvents generated in a tank 2 meters distant from the extraction point. Other mechanical considerations,producing <br /> performance deficits within the extraction apparatus,make it essential that theoretical air velocities are multiplied by <br /> factors of 10 or more when extraction systems are installed or used. <br /> Personal protectio0@0 <br /> n <br /> P Safety glasses with side shields <br /> Chemical goggles. <br /> Contact lenses may pose a special hazard;soft contact lenses may absorb and concentrate irritants.A written policy <br /> document,describing the wearing of lenses or restrictions on use,should be created for each workplace or task.This <br /> should include a review of lens absorption and adsorption for the class of chemicals in use and an account of injury <br /> Eye and face protection experience.Medical and first-aid personnel should be trained in their removal and suitable equipment should be readily <br /> available.In the event of chemical exposure,begin eye irrigation immediately and remove contact lens as soon as <br /> practicable.Lens should be removed at the first signs of eye redness or irritation-lens should be removed in a clean <br /> environment only after workers have washed hands thoroughly.[CDC NIOSH Current Intelligence Bulletin 59],[AS/NZS <br /> 1336 or national equivalent] <br /> Skin protection See Hand protection below <br /> Hands/feet protection Wear general protective gloves,eg.light weight rubber gloves. <br /> Body protection See Other protection below <br /> No special equipment needed when handling small quantities. <br /> OTHERWISE: <br /> Other protection Overalls. <br /> Barrier cream. <br /> Eyewash unit. <br /> SECTION 9 PHYSICAL AND CHEMICAL PROPERTIES <br /> Information on basic physical and chemical properties <br /> Appearance Orange brown odourless liquid,mixes with water. <br /> Physical state Liquid Relative density(Waterl� I 0.997 <br /> Odour Not Available Partition coefficient Not Available <br /> n-octanol/water <br /> Odour threshold Not Available Auto-ignition temperature Not Applicable <br /> (IC) <br /> pH(as supplied) 4.5-5.8 Decomposition Not Available <br /> temperature <br /> Melting point/freezing Not Available Viscosity(cSt) Not Available <br /> point(°C) <br /> Initial boiling point and Not Available Molecular weight(g/mol) Not Applicable <br /> boiling range(°C) <br /> Flash point(°C) Not Applicable Taste Not Available <br /> Evaporation rate Not Available Explosive propertiesNot Available <br /> Flammability Not Applicable Oxidising properties Not Available <br /> Upper Explosive Limit Surface Tension(dyn/cm <br /> Not Applicable Not Available <br /> (%) or mN/m) <br /> Lower Explosive LimitVolatile Component <br /> (%) Not Applicable (%vol) Not Available <br /> Vapour pressure(kPa) Not Available Gas group Not Available <br /> Solubility in water Miscible pH as a solution(1%) Not Available <br /> Vapour density(Air=1) Not Available VOC g/L Not Available <br /> SECTION 10 STABILITY AND REACTIVITY <br /> Reactivity See section 7 <br /> Continued... <br />
