Töötervishoiu- ja tööohutusalaste dokumentide tutvumise käigus selgus, et esmaabiandjaks on määratud juhatuse liige. Kontrolli käigus ei olnud esitada määratud esmaabiandja koolitust kinnitavat tunnistust, kuid juhatuse liige kinnitas, et viimane koolitus toimus umbes 6-7 aastat tagasi. Esmaabi täiendkoolitus peab toimuma iga kolme aasta tagant.
