Epwji/i Vo cannot emphasise too strongly that the uce of any of the Aroclora at elevated temperatures nuot Include provisions for exhauot ventilation. Although the hazard of vapor exposures nay not be quite as great with the solid and resinous Aroclora, thcro Is evidence that oven with these, harmful concentrations of vapors nay be liberated In a worlcroom atmosphere. For example, we aro now faced with a oult alleging ln.Jui-y from Aroclor AMGp where the use of this material Involved baking a particular formulation in an oven. As wo understand It, the oven was not vented to the outdoors. Unless a potential customer Is in a position to do atmoopherlo analysis to determine Aroclor vapor concen tration, we have no choice but to point out as definite as possible that any Aroclor mutt not be used at elovated temperature without adequate ventilation.
