Akcija „Ar geras gimnazijos patalpų mikroklimatas?“

Grynas oras yra viena svarbiausių sąlygų užtikrinti gerai žmogaus savijautai ir gyvenimo kokybei. Didžiąją dienos dalį mokiniai ir mokytojai praleidžia klasėse, todėl patalpų oro kokybė yra ypač svarbi.

 

Norėdama atkreipti dėmesį į mokymosi patalpų mikroklimato svarbą, visuomenės sveikatos priežiūros specialistė Laimutė Marcalienė kovo mėnesį Jotvingių gimnazijoje vykdė akciją „Ar geras mokyklos patalpų mikroklimatas?“

 

Akcijos metu specialiu prietaisu klasėse, koridoriuose, valgykloje, sporto salėje, persirengimo kambariuose buvo tikrinama patalpų temperatūra, oro drėgnumas, anglies dvideginio koncentracija. Ir mokiniai ir mokytojai smalsiai stebėjo kokius rodmenis pamatys prietaiso ekrane. Buvo įdomu stebėti kaip mažėja CO2 koncentracija atidarius langą. Visi sutarė, kad nori mokytis ir dirbti išvėdintose klasėse, nes tada gautų geresnius mokymosi rezultatus, būtų puiki darbinė nuotaika.

 

Kokios higienos normos mokykloms?

 

Mokyklos higienos normose yra nurodyta , kad mokymo kabinetuose, aktų salėje oro temperatūra turi būti 18 - 22 c C, sporto salėje - 15 - 17 c C, persirengimo kambariuose - ne mažesnė kaip 20 c C.

Santykinė oro drėgmė mokyklos patalpose turi būti 35 – 60 procentų.

Mokymo klasėse vidutinė anglies dvideginio (CO2 ) koncentracija, išmatuota laikotarpiu nuo pamokų pradžios iki pamokų pabaigos, neturi viršyti 2745mg/m3 (1500ppm).

 

Kaip gali kenkti mokinių sveikatai patalpų užterštumas?

 

Dėl prastos patalpų oro kokybės mokiniams ir mokytojams gali grėsti rimtos sveikatos problemos: galvos skausmas, mieguistumas, astmos priepuolių padažnėjimas, alergijos paūmėjimas, kosulys, čiaudulys, akių ašarojimas ar sudirgimas ir kiti negalavimai.

 

Neretai patalpose pasitaikantys biologiniai teršalai – bakterijos, virusai, grybų sporos (pelėsiai) neaplenkia ir mokyklos patalpų. Bakterijas ir virusus ore paskleidžia susirgę žmonės, todėl šaltuoju metų laiku, padidėjus sergamumui peršalimo ligomis ir gripu reikia ypatingą dėmesį skirti mokyklos patalpų valymui ir vėdinimui. Mokykloje reikėtų po kiekvienos pamokos, kai nėra mokinių, gerai išvėdinti klases.

 

Jeigu klasėse per didelė anglies dvideginio koncentracija jaučiamas galvos svaigimas, silpnumas, mieguistumas, oro trūkumas, gali sutrikti koncentracija, atsirasti dėmesio stoka, pagreitėti širdies ritmas, kartais atsiranda pykinimas. Geras patalpų vėdinimas sumažina CO2 koncentraciją.

    I was going through a rough time in my life and it greatly affected my union with my wife. We had so many emotional problems and struggles and this alone made us pay less attention to each other's need. While i was on it trying to fix my problems and get back on my feet so that i can reshape my marriage and make it work better, my wife had women around her that influenced her wrongly and made her took the wrong part by walking away. That incident alone broke me and i was sure she wasn't doing everything she doing with her right senses. I did what i can to restore peace but it never worked and i had to Contact Dr Isikolo who made it possible for me fix the problem. He worked for me and restored back the love and connection between me and my wife and she returned back home. The result of his work started manifesting just after 48 hours as promised and i can bold say everything is fine between us now and we are both happy together, I am here to validate the information out there that Dr Isikolo is a good and honest man that you can trust to help you with your problems.
