Safety Notes

  • Ensure site control of energy procedures are followed when installing Hot Spots®. Working within the confines of a conveyor can cause serious injury or death.
  • Ensure the surface that the Hot Spots® are being attached to are free of dirt, grease or other foreign materials, that will cause poor thermal communication between the surface being monitored for temperature and the Hot Spots® magnetic surface.
  • Caution removing Hot Spots® when thermal indicators have activated, as the Hot Spots® and or the device it is attached to may be hot.
  • Hot Spots® are intended to be supportive and used in conjunction with existing controls relating to statutory conveyor inspections.
  • Hot Spots® are magnetic and are intended for surfaces that support magnetism.
  • Installation in continuous UV light may reduce the life of Hot Spots®.
  • Hot Spots® are a low power neodymium magnet but should still be handled with care. Avoid contact with credit cards, watches, computer hard drives and electronic devices.
  • Hot Spots® are a ferrite grade of stainless steel to assist with its magnetic force. Some oxidisation will occur over time on the exposed metal.
  • Hot Spots® have a water and oil resistant PET seal over the active thermochromic dye to increase the life cycle of the product. Avoid direct high pressure hosing and or submersion in liquids where possible.
  • Replace Hot Spots® immediately if any signs of damage or waterlogging during inspections.
  • Hot Spots® magnetisation level can be reduced when exposed to temperatures greater than 150°C.
  • Avoid removing the Hot Spots® bulk applicator and inspection / maintenance dispensers end caps, whilst there are still Hot Spots® in the units. The containers contain a compression spring for dispensing the Hot Spots® and could cause injury if released under compression.
  • Store Hot Spots® out of direct sunlight and away from radiated heat sources.

Magnet Safety Warning


  • Magnets must be handled with care. They are often much more powerful than most people expect.
  • The correct safety equipment & PPE should be worn, especially when dealing with larger magnets. (Gloves, glasses) Magnets, especially large neodyminium magnets, often snap together or to near metal objects. Be careful of catching fingers and potential pinch points.
  • Magnets should be kept away from credit cards, computer hard drives, watches, TV’s electronic devices & objects.
  • Place the magnet onto a surface slowly & carefully. Do not allow the magnet to snap or smash onto the parent metal or it could damage either item.
  • High temperatures (+100° C.) can demagnetise Rare Earth / neodyminium magnets.
  • Storage with different types of magnets can demagnetise them.
  • People with pacemakers MUST avoid magnets.
  • Keep magnets out of the reach of children.
