Basic Hotwork Safety

HOT things are HOT

  • Assume everything you touch is hot until proven otherwise
  • Gloves buy you time – they don’t make you invincible

HEAVY things are HEAVY

  • Wear closed toe shoes
  • Lift carefully
  • Ask for team lift if necessary
  • Watch out for fingers

SHARP things are SHARP

  • Cut metal edges often have razor sharp burrs
  • Deburr your parts and wear leather gloves (but not near rotating machinery)

BRIGHT things are BRIGHT

  • Yell out “WELDNG” to alert your peers 3 seconds before starting to weld
  • Use welding hoods / masks, curtains, and doors to protect your vision

LOUD things are LOUD

  • Many processes in the shop are 85 db and above and can permanently damage hearing
  • Use ear plugs or muffs to protect yourself – playing music doesn’t help

Check for Flammable Materials Before Starting Work

  • Look for and remove:
  • Flammable liquids
  • Rags
  • Paper debris
  • Garbage
  • Plastic

Everything Must be Cool Enough to Touch Before Leaving

  • Don’t leave booby traps for the next person
  • Don’t leave potential smoldering fires

In case of Fire

  • MIT policy is do not fight fires. Evacuate the shop and pull alarm  on your way out.
  • There is a fire extinguisher in the shop.
  • Report even small fires using the safety report cards

No Woodworking in the Hot Shop

  • Wood dust is flammable / explosive

Power Tool Safety

  • Get a safety orientation before operating the disc grinder or ironworker for the first time
