What does PASS stand for? - Pull, Aim, Squeeze, Sweep (stand back 20 feet, aim at base of fire) What is travel distance? - The actual walking distance from any point to the nearest fire extinguisher. Fire extinguishers shall be located along normal travel paths within a ____ foot travel distance. - 30 What determines a genuine PFE tag? - A 3 inch by 1/4 inch high quality silver hologram that changes color as it is moved against the light. What does a PFE COF stamp show? - Information of the COF holder who performed the work on it. What will a QR Code display? - An FDNY approved company PFE list. How often does a PFE require a quick check? - Monthly. What does a PFE quick check look for? - Charge, location, integrity & damage. How often must a PFE tag be replaced, and by who? - Annually, by a W-96 COF holder from an FDNY approved company. Who performs a PFE quick check? - An employee selected by the business owner. In terms of air compressor supervision, who should be notified if an unsafe condition has been created? - The site safety manager. Anyone who becomes aware of a fire, explosion, major spill or other emergency shall do what? - Call 911 (Fire Department). An air compressor should be raised at least ____ feet above ground level to avoid drawing in any flammable gases. - 5 What does the unloading valve do? - It allows the air to escape from the compression chamber when there is a strain on the electrical motor. What does the check valve do? - It ensures that compressed air does not flow out when the unloading valve activates. It prevents the backflow of air from the tank to the compressor head. Where must the check valve be installed? - Between the air compressor head air line and the unloading valve. What does the pressure gauge do? - It indicates the pressure inside the air receiver. What does the pressure relief valve do? - It allows air to escape from the system when the pressure is too great. What is the intake valve fitted with? - A filter that prevents dust from being drawn into the cylinder. What does the filter and moisture separator assembly (FMSA) do? - It removes moisture and dust from the compressed air before it enters the air receiver. Where must the filter and moisture separator assembly (FMSA) be installed? - Between the air compressor and the air receiver. What is a drain cock used for? - To drain water and dirt from the filter and moisture separator assembly (FMSA). What does the automatic control device do? - It starts the compressor when there is a need for more pressure, and it shuts down the compressor when pressure is adequate. What does the safety relief valve do? - It keeps the air compressor tank from bursting should the pressure switch stop working. What does the constant speed control switch do? - It allows the air compressor to run continuously while supplying the desired amount of air. If the demand drops, excess air is allowed to escape via the pressure release valve. What does the cooling system do? - It prevents the compressor from overheating. Small compressors are usually ____ cooled with a fan. - Air.
