FDNY COF P-98 EXAM AND PRACTICE EXAM ACTUAL EXAM 275 QUESTIONS AND CORRECT DETAILED ANSWERS (VERIFIED ANSWERS) |ALREADY GRADED A 1.- Where generally *Fuel-oil is used in buildings?* What purposes?* - ANSWER- Is used in *Stationary Equipments*, Two purposes: a) *Fuel Emergency Generators* b) *Fuel Equipment used to heat the building* 2.- What *COF is required* to supervise the *Fuel-oil transfer in the building from one floor to another?* - ANSWER- *P-98 and maintain all qualifications and comply w/ requirements applicable to such certificate holder* *The P-98 COF is premise-related* 3.- The use of the word *should* refers to: - ANSWER- *Polices, procedures and / or best practices recommended by the FDNY* 4.- The use of the word *shall* refers to: - ANSWER- *Requirement of the Fire Code or the FDNY* 5.- *Supervision of Fuel-Oil Piping & Storage Operation* Shall be under the *GENERAL SUPERVISION* of P-98: - ANSWER- *A stationary fuel-oil storage tank, related piping, that is installed on the lowest floor of the building and transfer fuel-oil through piping to another stationary fuel-oil storage tank, or fuel burning equipment, installed above such floor* 6.- *Supervision of Fuel-Oil Piping & Storage Operation* Shall be under the *PERSONAL SUPERVISION* of P-98 COF shall be? - ANSWER- *Periodic Inspection and Testing of tanks and piping* 7.- *Maintenance Requirements* Fuel-oil storage tanks and piping *shall be inspected* for any evidence of leaks? - ANSWER- *Weekly* 8.- *Maintenance Requirements* Fuel-oil storage tanks *shall have their float switches tested* to ensure that they are in good working order at least? - ANSWER- *Weekly* 9.- *Licences & Certificates* *No* oil burning equipment *may operated until?* - ANSWER- a) *Certificate of Compliance* has been issued by *NYCDOB* b) *Air pollution control code* requirements *NYCDEP* c) *Permit for the Storage & use of fuel-oil* issued by *FDNY* 10.- *Licences & Certificates* Pursuant to the *New NYC Fire Code & Mechanical Codes* stated that? - ANSWER- *The COF is required for all existing and new buildings where fuel is being transported from the lowest levels to tanks or equipment on upper floors* 12.- *Oil Circulation in the System* What the *oil storage tank* do? - ANSWER- *Provides the supply of oil for combustion in the oil burner. It's inside a dike. In case of leak the diked area will contain the oil.* 13.- *Oil Circulation in the System* How is the #2 fuel-oil in its *normal condition*? - ANSWER- *Is thin and light and is easily pumped through the circulation system.* 14.- *Oil Circulation in the System* *What the suction pump do?* - ANSWER- *Circulates the oil throughout the system. Dirt and sediment are present in the fuel-oil coming from the oil storage tank. The oil filter removes most of these contaminants from the oil before the oil reaches the burner's strainer.* 15.- *Oil Circulation in the System* How many inches has to be the *SUCTION LINE?* - ANSWER- *6 inches from the bottom of the tank for sediments not to be absorbed* 16.- *Oil Circulation in the System* What is the *vacuum gauge?* - ANSWER- *A device that measures pressure below atmospheric pressure.* 17.- *Oil Circulation in the System* *Excessive vacuum readings* means? - ANSWER- *Indicate that there is an obstruction in the suction line (such as dirty oil strainer) when this occurs the flow of oil can be stopped by closing the shut-off valve.* 18.- *Oil Circulation in the System* Closing the *shut-off valve.?* - ANSWER- Flow of oil *STOP* *This permits the operator to clean the filter/strainer or to perform other maintenance* 21.- *Oil Circulation in the System* How operated the *Main Fuel Valve?* - ANSWER- *The main fuel valve is electrically operated and will open or close the line leading to the atomizer* only for oil burners. 22.- *Oil Circulation in the System* The *Main Fuel Valve...* - ANSWER- *It will SHUT DOWN the burner system if there is a failure of ignition or combustion* 23.- *Oil Circulation in the System* *Oil circulates through the piping system back* to....? - ANSWER- *The storage tank through the oil return line* 24.- *Oil Circulation in the System* For Safety is provide a *Back Pressure Relief Valve* - ANSWER- *If the pressure becomes too great...* 25.- *Oil Circulation in the System* Where is located a *Day Tank*? - ANSWER- *May be located throughout the building above the lowest floor* 27.- *Oil Circulation in the System* Is required a *Separate pump*? - ANSWER- *Yes, is required for each* DAY TANK *to supply each floor* 28.- *Oil Circulation in the System* In case of a *leak in the piping.....?* - ANSWER- *Leak collector is provided. Leak collector is stored by the storage tank* 30.- *Oil Circulation in the System* Leak collector has a *gauge?* - ANSWER- *Yes, It has a oil level gauge which shows the amount collected.* *A gauge will show how much oil is inside a main storage tank/day tank* 33.- *Oil Burner Operation* What is a *combustion?* - ANSWER- *Combustion is the chemical union of the oxygen in the air with combustible elements in fuel-oil* (hydrogen and carbon). 34.- *Oil Burner Operation* What is the *end result of combustion?* - ANSWER- *The production of heat energy. Oil firing equipment is used to liberate heat energy from fuel-oil.* 35.- *Oil Burner Operation* The *principal components* of the oil *firing equipment?* - ANSWER- *Oil burners are the principal components of the oil firing equipment and provide the means of supporting the process of combustion.* 36.- *Oil Burner Operation* What are the *two principal elements of fuel-oil?* - ANSWER- Carbon and hydrogen. *During the combustion process, the carbon content of fuel-oil (about 85%) unites with the oxygen in the air and forms carbon dioxide and carbon monoxide. The hydrogen content of the oil (about 14%) unites with the oxygen and produces water. The objective is to have a complete combustion process* 37.- *Oil Burner Operation* *In order to support combustion?* - ANSWER- *It must be changed to a gas or vapor and mixed with air* 38.- *Oil Burner Operation* The *Oil burner?* - ANSWER- *Is primarily a device for processing the liquid fuel for combustion by accelerating the change from liquid to a vapor that can be mixed with air and burned.* 39.- *Oil Burner Operation* Why is necessary *atomizing oil?* - ANSWER- *This process of breaking down or atomizing the oil is to ensure prompt ignition and rapid combustion. Although there are various types of oil burners, i.e. generator or boiler, they all vaporize or atomize the oil before it enters the combustion chamber where it is mixed with air in predetermined proportions.* 40.- *Oil Burner Operation* Oil burner uses an *oil pump?* - ANSWER- *An oil burner uses an oil pump and mixes air and oil within the nozzle itself. In oil burners, the oil and air mixture is delivered to the nozzle at a pressure dependent upon the make of the burner. The air that contacts the oil prior to its leaving the nozzle is referred to as primary air.* 41.- *Oil Burner Operation* What is *Secondary air*? - ANSWER- *The introduction of air from the blower or fan into the combustion chamber after the oil has left the nozzle is referred to as "secondary air". Every brand of oil burner is essentially different from that of other manufacturers* 42.- *Oil Burner Operation* The *Diesel generators* - ANSWER- *use injection nozzles without primary air, thus it is important that an operator of a system understand the functions of his/her particular system completely.* 43.- *Oil Burner Operation* Oil burners *required approximately?* - ANSWER- *2000 cubic feet of air per gallon of oil consumed. The mixture of oil and air is sprayed in vapor form into a firebox area (the combustion chamber) where combustion takes place*
