<\/p>\nEl m\u00f3n est\u00e0 trasbalsat per la pand\u00e8mia de la Covid-19 i tots els experts estan d’acord en que cal complir estrictament les mesures de seguretat per evitar, o al menys, reduir al m\u00e0xim el risc de contagi.<\/p>\n
Els tres aspectes clau s\u00f3n:<\/p>\n
<\/p>\n
Per\u00f2 nosaltres hem tornat a les aules, i un altre cop els experts ens han donat una instrucci\u00f3 clara: Cal mantenir ben ventilades les aules per reduir el risc de contagi de Covid<\/strong>.<\/p>\n Per\u00f2, a m\u00e9s a m\u00e9s de la Covid, tenim un altre bon problema. S’apropa l’hivern i tots coneixem la dura climatologia de les terres de Ponent en aquesta estaci\u00f3. Esmicolem-lo una mica per veure’n totes les seves conseq\u00fc\u00e8ncies:<\/p>\n Davant de tants fronts oberts cal mantenir la calma i actuar amb criteri, primer, per\u00f2 tamb\u00e9 amb imaginaci\u00f3 i utilitzant totes les petites eines que puguem tenir al nostre abast.<\/p>\n Els experts del CSIC recomanen avan\u00e7ar en sistemes de ventilaci\u00f3 o purificaci\u00f3 de l’aire i combinar-los amb l’obertura de finestres. La ventilaci\u00f3, a m\u00e9s a m\u00e9s, varia segons la mida de la classe, el nombre d’alumnes i la seva edat, o la incid\u00e8ncia de la Covid a la zona. Alguns experts assenyalen que \u00e9s necessari obrir les finestres una mitjana d’entre cinc i sis vegades cada hora, la qual cosa permet renovar 14 litres d’aire per persona i segon (Font: ccma.cat<\/a><\/em>).<\/span><\/p>\n Les persones expulsem unes part\u00edcules, anomenades aerosols, quan parlem, riem, tossim i, sobretot, cridem o cantem, i la seva acumulaci\u00f3 a l’aire pot provocar contagis. La ventilaci\u00f3 permet substituir l’aire interior “potencialment contaminat” i eliminar part\u00edcules en suspensi\u00f3 que poden contenir el virus, segons afirmen els experts.<\/p>\n Per reduir la presencia d’aquestes part\u00edcules recomanen tamb\u00e9 altres mesures, com ara (Font: ccma.cat<\/a><\/em>)<\/span>:<\/p>\n El mesurador W\u00f6hler \u00e9s un dels aparells que forma part del projecte de la Motxilla bioclim\u00e0tica<\/a>.<\/p>\n Aquest instrument mesura el nivell de CO2, la temperatura i la humitat de l\u2019aire. Enregistra els valors per disposar de dades hist\u00f2riques. Est\u00e0 dissenyat per avaluar la qualitat de l\u2019aire en espais tancats.<\/p>\n Si b\u00e9 totes aquestes dades poden ser molt interessants, la concentraci\u00f3 de CO2 \u00e9s especialment rellevant per con\u00e8ixer de forma orientativa amb quina freq\u00fc\u00e8ncia hem de ventilar l’aula. \u00c9s important, per\u00f2, tenir en compte que cada espai i grup d’alumnes t\u00e9 unes necessitats de ventilaci\u00f3 diferents. Per aquest motiu, us convidem a analitzar amb el mesurador cada aula i grup d’alumnes de manera individual. Per fer-ho, us facilitem una guia que recull:<\/p>\n Guia d’\u00fas i d’aplicaci\u00f3 a l’aula (feu clic per descarregar<\/a>).<\/p>\n La ventilaci\u00f3 de les aules i la Covid-19 El m\u00f3n est\u00e0 trasbalsat per la pand\u00e8mia de la Covid-19 i tots els experts estan d’acord en que cal complir estrictament les mesures de seguretat per evitar, o al menys, reduir al m\u00e0xim el risc de contagi.
