Today there are various fire hose nozzles in the market and therefore making the right choice is becoming a big challenge. It will require you to determine the agency fire flow before investigating the best nozzle for your fire flow operations. The factor will be essential toward the overall success of the choice of the hose nozzle to choose. It will, therefore, need you to have some various questions concerning the departmental operations together with their answers to assist your determination.
It will require you to understand the liters that will be needed for the absorption of the heat generated by the fire in the initial attack. More to that you will need to know the predicable fires, their size, and content basing with the department historical experience. The other essential thing is knowing the firefighter’s experience level that will be expected to participate in the operations of initial attack.
After getting some reviews and considering the fire flow formulas you will have the ability to determine the target fire flow. The minimum flow that will be provided to the team of nozzle will be useful for the determination of discharge pressure of pump after considering the length and the size of the hose together with the operating pressure of the nozzle. After having the determination of the losses, pressures, and the minimal flows, then the guidelines of the operations can be established to repeatable and consistently provide the operator of the nozzle with critical flow performance.
From there you will be in a position to pick the best nozzle to fulfill the needs of an agency’s operations. From the benefits standpoint and the features it is vital to review the criteria of key performance and offer drawbacks and benefits for every characteristic. The initial evaluation elements include the shut-off valve, nozzle pressure configuration, fog tooth design, and sharper configuration pattern.
With the agreement of choice, you will need to understand the solid stream or the capability of the fog nozzle and the time to utilize them. Any person can be able to make the decision of usage of single nozzle and ensure all situations are fitting the nozzles parameters. It is necessary, therefore to know how each nozzle is bringing to the party to help you in selecting the best tool for your work. Ensure to choose the most effective fire hose nozzle basing on the possibility that individual may be near the fire seat.
The other thing you will require to check is the steam production when water is hitting the fire. With the use of fog nozzle or solid stream that is positioned on the solid stream, you will have the ability to rescue victims and ensure there is a reduction of steam production. The other thing you require to do after the charging, deploying, and selecting of the attack line is to open the nozzle to bleed the air and consider to check the nozzle pattern.
The choice of getting the proper fire hose nozzles is not that easy. However, with more investigation and determination of the target fire flow of the agency and identification of the key performance criteria that are necessary to the operations you will have better choice.
