Fire Hose Nozzle Adjustable High Quality

Fire hoses are professional firefighting equipment and are only for use by trained firefighters and dedicated firefighters of the unit. Non-professionals are strictly prohibited from operating them without authorization.
Before use, it is necessary to check whether the fire hose is within the valid period of inspection (fire equipment needs to be inspected regularly, usually once a year). It is strictly forbidden to use expired, untested, damaged or non-compliant fire hoses.
When connecting the fire hose to the water hose, ensure that the interfaces match (such as a 65mm fire hose with a 65mm hose interface), and after connection, check the sealing performance to prevent water leakage under high pressure, resulting in pressure loss or injury to personnel.
During operation, wear a complete set of personal protective equipment (PPE), including fire helmets, fire suits, fire gloves, fire boots, and air respirators, to avoid injuries from water impact, high-temperature objects, and flame burns.
It is strictly prohibited to spray water hoses at people, even in low-pressure conditions, as the water impact force may cause contusions, fractures, etc. to the human body; even more so, do not use the body to block the high-pressure water flow without protection.
When the fire hose is in operation, there is high pressure inside the gun body and the water hose. It is strictly forbidden to disassemble the interface, adjust the nozzle, or perform maintenance under pressure. First, turn off the water supply source and release the pressure before operating.
Avoid colliding, dragging, or stepping on the fire hose with sharp objects to prevent deformation of the gun body and damage to the nozzle, which may affect the spraying performance.
When fighting electrical fires, it is necessary to first confirm that the power has been cut off, or use a spray water gun with an insulation performance that meets the standard (insulation grade should comply with GB 15090 - 2005 standards), and maintain a safe distance (not less than 0.5m for voltages below 380V, and follow the power safety regulations for high-voltage electricity).
When fighting oil or chemical fires, pay attention to the water flow direction to avoid direct water column impact on the liquid surface, which may cause the fire to spread. Use spray or mist water flow to cover and suffocate the fire first.
