Safety Horn Inspection Recommendations

All of our safety horns and components are inspected and tested during manufacture and prior to packing and shipment.  We recommend that you inspect any horns upon receipt as things can happen in transit.  Each horn is tested to be sure they meet the required quality dB requirements.  All canisters follow required DOT manufacture requirements for compressed gas products.  The following inspections should be performed and recorded:

  • If product has been shipped to you, visually inspect the outer and inner packaging to ensure they haven’t been damaged in any way from shipping and handling.
  • Visually inspect all components and assemble horn as directed.  Be sure to tighten without overtightening.  Sound horn to be sure device is in working order.
  • Once assembled, weigh and record the completed horn and place in storage location for emergency use.
  • Be sure horn is stored in a cool, dry location and protect from tampering, heat sources, and direct sunlight.  Never store in enclosed vehicle or where temperatures can exceed 120°F/49°C.


Monthly Inspection Recommendations:

  • Visually inspect all components and check for tampering, cracks, or rust.
  • Weigh completed horn and compare with original received weight.  Record weight for inspection comparison.
  • Test if required to ensure completed horn is in working order (see attachment for average number of blasts for the safety horn you have).  Remember to include the number of 1-2 second blasts when calculating shelf life.
  • Replace horns if blast life is exhausted or there is evidence of damage or tampering.  NEVER USE A HORN THAT HAS BEEN DAMAGED OR IS NOT IN PROPER WORKING ORDER.  REPLACE IMMEDIATELY.  Products contain compressed gas, not air.  Always follow SDS recommendations for use and storage.
  • Recommended replacement of our larger sized 8 oz., 5.5 oz., and 5 oz. horns is every 5 years if still in working condition or when gas level is at 50% based on weight.
