7、conjunction withan existing health and safety program.The information pro-vided cannot be used as a substitute for expert safety andmedical advice,but rather as a supplement to such advice.4.Description of Products4.1 Phenol is a colorless to light pink crystalline materialwhich melts at 40 to 41C(1
8、04 to 106F).Technical and USPgrades melt at lower temperatures.4.2 Phenol is both extremely hygroscopic and sensitive todiscoloration.Therefore,it cannot be overemphasized thatproper precautions must be undertaken when unloading orsampling the product.Moisture must be excluded.The use ofsampling dev
9、ices that contain metals that may catalyze discol-oration(iron,copper)must also be avoided.4.3 Cresylic acid is a common chemical name applied tomixtures of alkyl-substituted phenols.Included are mixtures ofcresols,xylenols,and higher alkylated phenols.Many cresylicacid mixtures contain measurable a
10、mounts of phenol.4.4 Most cresylic acid mixtures are liquids at ambienttemperatures.However,at low temperatures(0C)they some-times become very viscous and difficult to pour.Some mixturescontaining high concentrations of high melting isomers mayform thick slurries or become solids at low temperatures
11、.4.5 While phenol or cresylic acids are highly dangerouswhen handled improperly,particularly at the elevated tempera-tures sometimes required to unload tank cars or tank trucks,handling and sampling need not be hazardous provided thedangers are recognized.Proper precautionary measures mustbe provide
