2. Maagizo Muhimu ya Usalama
Wakati wa kutumia vifaa vya umeme, tahadhari za kimsingi za usalama zinapaswa kufuatwa, pamoja na zifuatazo:
- Soma maagizo yote kabla ya kutumia kifaa.
- Usijaribu kuendeshea oveni hii mlango ukiwa wazi kwani hii inaweza kusababisha mfiduo hatari kwa nishati ya microwave.
- Usiweke kitu chochote kati ya uso wa mbele wa tanuri na mlango au kuruhusu udongo au mabaki ya kisafishaji kujilimbikiza kwenye sehemu zilizoziba.
- Usifanye kazi ya oveni ikiwa imeharibiwa. Ni muhimu sana kwamba mlango wa oveni ufungwe vizuri na kwamba hakuna uharibifu kwa: (1) mlango (ulioinama), (2) bawaba na latches (zilizovunjika au kufunguliwa), (3) mihuri ya milango na nyuso za kuziba.
- Tanuri haipaswi kurekebishwa au kutengenezwa na mtu yeyote isipokuwa wafanyakazi wa huduma waliohitimu ipasavyo.
- Vimiminika au vyakula vingine havipaswi kuwashwa katika vyombo vilivyotiwa muhuri kwani wanahusika kulipuka.
- Tumia tu vyombo ambavyo vinafaa kutumika katika oveni za microwave.
- Wakati inapokanzwa chakula katika vyombo vya plastiki au karatasi, weka macho kwenye tanuri kutokana na uwezekano wa kuwaka.
- Ikiwa moshi utaonekana, zima au chomoa kifaa na ufunge mlango ili kuzima miali yoyote ya moto.
- Kifaa hiki hakikusudiwa kutumiwa na watu (pamoja na watoto) walio na uwezo mdogo wa kimwili, hisi au kiakili, au wasio na uzoefu na ujuzi, isipokuwa wamepewa usimamizi au maagizo kuhusu matumizi ya kifaa na mtu anayehusika na usalama wao.
- Watoto wanapaswa kusimamiwa ili kuhakikisha kwamba hawachezi na kifaa.
