  • Sit gereedskap so neer dat die snykant weg van jou naaste maat is.

VEILIGHEID TEN OPSIGTE VAN ELEKTRISITEIT

Verskeie projekte vereis òf hoofstroomelektrisiteit òf battery-elektrisiteit. Kennis moet geneem word dat water en vog elektrisiteit gelei. Alle elektriese toestelle moet met sorg hanteer word, veral kondensators. Batterye moet verkieslik in aparte houers gebêre word. Batterye moet uit stroombane verwyder word. Stroombane moet oop wees as projekte gebêre word. Moenie met hoofstroomelektrisiteit speel nie, want jy kan jou doodskok. Skok kan ernstige brandwonde en ander beserings veroorsaak.

Hoe om ‘n elektriese toestel aan te skakel

  • Kontroleer dat die toestel afgeskakel is.
  • Kontroleer dat die sok afgeskakel is.
  • Kontroleer of die elektriese koord en prop nie beskadig is nie.
  • Druk die prop in die sok.
  • Skakel die sok aan by die muurskakelaar.
  • Skakel die apparaat aan by die skakelaar.

Hoe om ‘n elektriese toestel af te skakel

  • Skakel die toestel af by die skakelaar.
  • Skakel die sok af by die muurskakelaar.
  • Verwyder die prop van die sok.
