FRED is used when welding to protect the user and bystanders from welding fumes. Welders must also wear a P100 respirator when welding. It is not designed to protect against extremely toxic materials like metals with cadmium or lead.

#Check leads for damage. Ensure it is plugged in to power and that the compressed air line is connected, and the air turned on.
#Use the switch to turn on power.
#Position the end 12-20" from the source of fumes or dust. Do not extend the arm completely horizontally, as it increases the risk that sparks can travel all the way into the unit and start a fire.
#Turn off FRED once finished working. It will begin a filter cleaning cycle; do not turn FRED on again before the cycle has completed.


If you find evidence of smouldering or fire in the FRED, unplug power and air and pull the unit out of the large double doors to the outside of the building. Undo the two latches holding the door onto the firebox and spill the hot contents onto the concrete. Do not empty hot smouldering debris onto dry wood, flammable garbage, or plant matter outside.
