It will only be poaciblo In tho few minutes that have baer. cl lot. '"j to me to cover the moat ontotaniLrg hazerds associated with toxic nnterielc. i First, frees tko standpoint of tbs number of cmrloycoa exposed aud the general presence of the materiel throughout the Hefinery, one would have to list hydrogen end organic Bulfidoo. Prior to tbir- survey, several CE.S03 of eerious eye irritation cemo to the attention of the Kcd.icc.1 Division from a lov grade exposure of rather long duration to sulfides. At anothez location this nervoy diocloced that there vea e rcther aeriouo possibility of eye irritation iron the preeoncc of hydrogen sulfide. Before any action v.v. taken on the recommendation, such as instigating a dotal led study of thic location end re corni-ending adequate ventilation, several eye casco reported to the hospital for treatment from this unit. There .still exists the \noed for a detailed end quantitative invostig&tion of these sulfidoo in many olhciunite. This gz.3 has been responsible for very serious, acute poisoning end some eases have resulted in fatalitioa. Under the existing conditlono, th** procautions used, cad the concentrations cf sulfide that are nou found, ii io the opinion that the danger lo not only eye irritation, but possibly chronic systemic poisoning frea lov ooccentrctlcns, The currently used eulfide detector iG not esnsitivo enough to pick up ccrcentrations of these gaseo which, fill produce physiological effects. An adequate appraisal would depend upon ueing absolute quant!tative chemical cathode and integrated camples. There arc at least five skilled crafts where possibility of plui'.nlr.m exintoTo date no investigation of this problem in the nature cf either atmospheric sacplon or lead excretion values of body fluids has been carried \ - . out. This latter will socn be undertaken by the analytical laboratory. Mercury is extensively nsec by the laboratory analytical group, tha resoarch engineers, and handing in largo quantities by the Instrument Man.
