SUO J EC7,..CLASS IF ICA TIO NI S SUED BY De pa r t men t Emplovees who handle alkali metals must be thoroughly instructed as t o hazards, control measires and the mandatory f i r s t aid procedures- required t o help reduce severity of EMERGENCY Brush or scrape off metal particles quic ssi ble, &en FOR SKIN time. Then proceed t o Medical Aid Station, o r call the station, . PROCEDURE i s started, Continue irrigation for atleast 15 minutes. Lift upper immediately flood or immerse skin area w i t h water for a lengthy or have someone else call the station. Nothing is more important..than the speed with which 'water irrigation and lower eyelids frequently t o insure complete washing. attempt the use of neutralizing solutions i n the eyes,' Have someone else call the Medical Aid Station as soon as possible but do not delay or stop flushing the eye t o make the call. Fires involving alkali metals produce caustic fumes which may result in irritation of eyes or the rewiratory tract. exposed from fumes t o fresh air and transport t o Medical Aid Station as soon as possible.' HAZARD When no moisture is present, contact of dry alkali metal w i t h the ANALYSIS skin may cause no damage. No acute o r chronic systemic effects . * . are recognized. On contact w i t h moisture, sodium liberates hydrogen . , and enough heat i s produced so that this gas may be ignited. The . imnediate result is a severe thermal burn ; but as burning continues, the forming of sodium hydroxide may add injury i n the form of an alkali burn to the original thermal burn. All factors considered, the immediate flushing of skin and.eyes with water presently offer . the best chances for reducing tissue damage. t o the rule t h a t contact between sodium and water should be avoided. ..
