Veiligheid

Veiligheid

Gebruik veilige werkspraktyke en toon ‘n bewustheid van doeltreffende maniere om materiaal en gereedskap te gebruik.

Dit is belangrik om veiligheidsmaatreëls te ken en van die begin af toe te pas. Maak seker dat jy weet waar die Noodhulptas en die hoofskakelaar is. Onthou ook om alle ongelukke by jou onderwyser/ es aan te meld.

  • Dra altyd ‘n voorskoot af ‘n oorjas om jou klere te beskerm en toe skoene om jou voete te beskerm.
  • Trek jou baadjie / trui uit en rol jou moue op. Druk ook jou das se punte in jou hemp in.
  • Dogters moet lang hare uit hul gesigte hou deur dit in ‘n poniestert vas te maak.
  • Verwyder verkieslik alle juweliersware soos ringe, kettinkies en armbande.
  • Moenie onverskillig met gereedskap soos skroewedraaiers wees nie.
  • Moenie hardloop of rondspeel in die klas nie, veral nie met gereedskap in jou hande nie.
  • Moenie hardop uitskree terwyl daar met gereedskap gewerk word nie.
  • Jy mag nie alleen of sonder toestemming met enige gereedskap of masjiene werk nie.
  • Volg alle instruksies oor die gebruik van apparate noukeurig.
  • Dra skerp gereedskap naby jou lyf en met die skerp punt na onder.
  • Moenie gereedskap gebruik vir ‘n ander doel as waarvoor dit gemaak is nie.
  • Plaas gereedskap na gebruik terug op sy oorspronklike posisie.
  • Hou jou werkoppervlak en vloerspasie rondom skoon en netjies.
  • Gebruik elektriese toestelle slegs na deeglike opleiding en met toestemming.
  • Moenie elektriese toestelle in klam of nat toestande gebruik nie.
  • Slegs een leerder word op ‘n slag by ‘n elektriese toestel toegelaat.
  • Maak ‘n masjien skoon na gebruik en rapporteer enige probleme of beskadiging, soos bv. dat ‘n draadskêr stomp is.
  • Was jou hande deeglik en droog hulle af na elke les.
  • Was jou hande veral deeglik as jy met olie, chemikalieë, verf of gom gewerk het.
  • Moenie hout in jou een hand vashou as jy dit met die ander hand saag nie.
  • Moenie ‘n skroef in ‘n stuk hout indraai as jy laasgenoemde in jou hand vashou nie.

Moenie in die rigting van jou ander hand of jou lyf beitel nie.

  • Gebruik ‘n saagplank vir enige saagwerk.
  • 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.
