  • USE THE RIGHT TOOL – Don’t force a small tool or attachment to do the work of a larger industrial tool. Don’t use a tool for a purpose for which it was not intended.
  • DRESS PROPERLY – Don’t wear loose clothing or jewellery, they can get caught in moving parts. Protective, non-electrically conductive gloves and non-skid footwear are recommended when working. Wear protective hair covering to contain long hair and keep it from harm.
  • USE EYE PROTECTION – Use a full face mask if the work you’re doing produces metal filings, dust or wood chips. Wear a clean dust mask if the work involves creating a lot of sparks or coarse dust.
