PÄVÄKOTEN JA KOULUJEN PAKASTELATTEDEN LÄMPÖTLAMTTAUKSET SYKSYLLÄ 992 Oulun kaupunki ~ Ympäristövirasto Raportti 0/992. - Oulu
---------~-----,-- -,.." ; PÄVÄKOTEN JA KOULUJEN PAKASTE LATTEDEN LÄMPÖTLAMTTAUKSET SYKSYLLÄ 992 Syksyllä.0.-9.2.992 välisenä aikana mitattiin päiväkotien ja koulujen pakastekaappien ja -arkkujen lämpötiloja. Mittarina oli Extrabit Oy Wanderer Type WST - 0/3 No 095. Mittausaika oli yleensä 2 tuntia. Asetuksen pakastetuista, jäädytetyistä ja jäätyneistä elintarvikkeista (..977/797) mukaan pakastettua elintarviketta varastoitaessa on elintarvikkeen lämpötilan oltava -8 e tai sitä kylmempi. Tulokset: Kymmenen päiväkodin ja viiden koulun keittiöissä suoritettiin lämpötilamittauksia 7:stä pakastekaapista ja -arkusta. Liian korkeita lämpötiloja oli kolmessa pakastelaitteessa. Kahdessa tapauksessa tilanne parani pakastelaitteiden korjauksien ja lämpötilasäätöjen jälkeen. Yhden pakastekaapin lämpötila oli _5 0 e... - 8 0 e välillä n. 8 tuntia korjauksen jälkeenkin. Pakastelaitteiden mittauksia on aiheellista tehdä jatkossakin.
