Usage of compressed air is very effective, however is very dangerous if not handled properly. Recommended to use air with restricting nozzle, reduces safety risk without loosing cleaning effectiveness.
All approved air guns must have safety tip, if during pre-operational inspection found that air gun is missing nozzle, please report to supervisor, so it can be safely disconnected and removed from production floor.
