Study Notes

EQUIPMENT OVERVIEW

PPV Fans: Start daily; ensure no trash or plastic is on the fan.
Salvage Kits: Make sure the tools are in the kit (staplers, utility knives, window plastic). Make sure staple guns are loaded correctly and not jammed.
Quartz Lights: Check if the light holds its position. Check if working properly in conjunction with cords and extension cords.
Circular Saw: Ensure the blade is correctly installed and the nuts are tight. Check the blade and replace if needed. Start the saw and let it warm up (about 5 minutes).
Chain Saws: Make sure the chain is on correctly and has correct tension. Ensure chain does not have too many missing teeth. Start the saw and let it warm up (about 5 minutes). When running, place a towel under it to reduce vibrations and prevent damage.
Portable Generators: Start it and place a load (e.g., fan or light). Ensure generators are started and stopped with no load. Ensure auto throttle (if equipped) is off until warm-up.
Ladders and Pike Poles: Ensure straps are tight if pike poles are attached to the ladders. Ensure pike pole is close to the door.
Platform Ladder: Ensure there is a pike pole (at least 8 ft. minimum) in the fly section and axe in the bucket. Make sure the emergency stop switch is disengaged, and ensure the nozzles and water curtain are closed.
Aerial Ladder (Tiller): Ensure there is an 8 ft. minimum pike pole and an axe at the tip. Make sure the waterway intakes are closed on both sides.
