2. Segurtasun-argibideak
WARNING: Always follow basic safety precautions when using electrical appliances to reduce the risk of fire, electric shock, and personal injury.
2.1 Segurtasun orokorra
- Beti erabili babes pertsonaleko ekipamendu (EPI) egokia, segurtasun-betaurrekoak eta eskularruak barne, lanean ari zaren bitartean.
- Mantendu lan-eremua garbi eta ondo argiztatuta. Eremu nahasiak edo ilunek istripuak gonbidatzen dituzte.
- Ez erabili tresna elektrikoak atmosfera lehergarrietan, adibidez, likido sukoiak, gasak edo hautsak daudenean. Erreminta elektrikoek hautsa edo keak piztu ditzaketen txinpartak sortzen dituzte.
- Mantendu haurrak eta ingurukoak urrun, erreminta elektrikoa erabiltzen duzun bitartean. Distrakzioek kontrola galtzea eragin dezakete.
2.2 Segurtasun elektrikoa
- Ziurtatu elikadura hornidura boltagproduktuaren etiketako zehaztapenekin bat dator.
- Ez erabili kableari. Ez erabili inoiz kablea tresna elektrikoa eramateko, tiratzeko edo deskonektatzeko. Mantendu kablea bero, olio, ertz zorrotz edo mugikorretatik urrun.
- Saihestu gorputzaren kontaktua lurrarekin edo lurretik loturiko gainazalekin, hala nola hodiak, erradiadoreak, sukaldeak eta hozkailuak. Deskarga elektrikoa jasateko arriskua areagotu egiten da zure gorputza lurrarekin edo lurrarekin lotuta badago.
2.3 Segurtasun pertsonala
- Egon adi, ikusi zer egiten ari zaren eta erabili zentzua erreminta elektrikoa ustiatzean. Ez erabili tresna elektrikorik nekatuta edo drogen, alkoholaren edo botiken eraginpean zauden bitartean.
- Ziurtatu laneko pieza. Erabili clamppieza eusteko tornu bat edo torloju bat. Eskua erabiltzea baino seguruagoa da hau, eta bi eskuak askatzen ditu tresna erabiltzeko.
- Ez ezazu gainditzen. Mantendu oin eta oreka egokia uneoro. Horrek tresna elektrikoa hobeto kontrolatzen du ustekabeko egoeretan.
