Safety in practical lessons using heavy or fine items or projectiles

 

  • Large masses should not be suspended without suitable safeguards and warning. Broken toes or fingers may result!
  • Fine thread or wire should not be strung across pathways without card being hung on it to make others aware it is there, or a barrier of stools with a warning sign used to make others realize that there is danger (Young Modulus experiment!)
  • Masses 'bouncing' on springs, or pendula can take someone’s eye out! Goggles should be worn.
  • Projectiles sometimes go where they are not expected to! Goggles should be worn!
