Khalani kutali ndi magwero a kutentha, malo otentha, checheni, malawi otseguka, ndi magwero ena oyatsira. Musasute. Sungani chidebe kuti musatseke mpweya. Zotengera ndi zida zonyamulira ndizokhazikika ndipo zimalumikizidwa ndi equipotential. Gwiritsani ntchito zida zamagetsi / mpweya wabwino / zowunikira zomwe sizingaphulike. Gwiritsani ntchito zida zomwe sizitulutsa zopsereza. Chitanipo kanthu kuti mupewe kutulutsa ma electrostatic.

Pewani kupuma fumbi/utsi/gesi/aerosol/vapor/spray. Tsukani bwino pambuyo opareshoni. Gwiritsani ntchito kunja kokha kapena m'malo olowera mpweya wabwino.

Valani magolovesi oteteza / kuvala zodzitchinjiriza / kuvala chigoba choteteza m'maso / kuvala chigoba choteteza / kuvala zodzitetezera kumakutu.

Khungu (kapena tsitsi) likadetsedwa: Chotsani zovala zonse zomwe zakhudzidwa nthawi yomweyo. Sambani khungu lanu kapena kusamba ndi madzi. Ngati kuyabwa pakhungu: Pitani kuchipatala. Akapuma mwangozi: Kusamutsa munthuyo kumalo komwe kuli mpweya wabwino komanso kukhala ndi mpweya wabwino.

Pitani kuchipatala. Chithandizo chapadera.

Chotsani zovala zomwe zawonongeka ndikuzichapa musanagwiritsenso ntchito.

Moto ukayaka: Gwiritsani ntchito mpweya woipa, mchenga wouma kapena ufa wouma kuti uzimitse motowo.

Sungani pamalo abwino mpweya wabwino. Khalani ozizira.

Tayani zomwe zili mkati / zotengera molingana ndi malamulo am'deralo, chigawo, dziko ndi mayiko.
