In order to strengthen the response to marine accidents, the Fire Services Department invested 87 million yuan in the early years to purchase "Fireboat No. 7", which is the only rescue ship in Hong Kong equipped with equipment for handling chemical, biological, radiation and nuclear accidents.
The "No. 7 ship" is currently the fastest fire-fighting ship. The water cannons on the hull can spray water mist to cool down the temperature of other fire-fighting ships. Its "water curtain system" can wash away the toxic substances in the ship and play a self-protection function.
There are "remote control lifesaving buoys" and "underwater remote control robots" on board to assist in rescuing the injured and searching deep underwater.
The ship is equipped with air monitoring equipment to prevent toxic gases from flowing into the cabin, and biochemical rescue facilities can disinfect and check the bodies of contaminated wounded.
During the epidemic, "Ship No. 7" turned into a transport ship, carrying confirmed patients from outlying islands to isolation facilities for treatment.
And today (12th) it will be the first time to participate in the Daya Bay inter-departmental contingency plan exercise organized by the Security Bureau.
Small file of "Fireboat No. 7":
Cost: 87 million Hong Kong dollars
Origin: Made in Taiwan in 2015
Year of service: End of 2020
Specifications: About 35 meters in length and 12 meters in
width 35 nautical miles per hour
Structure: Made of aluminum alloy, designed catamaran
Carrying capacity: 107 people
Features: Two remote-controlled water cannons/bubble cannons with a range of up to 100 meters, water curtain protection for the entire hull, and chemical, biological, and nuclear detection systems
The "Fireboat No. 7" of the Fire Services Department was manufactured in Taiwan in 2015, with a value of 87 million. It will officially enter service at the end of 2020. It is the first civilian ship in Hong Kong to be certified by the classification society with nuclear, biological, chemical and radiation protection functions.
Top speed of 35 knots fastest among fireboats
"No. 7" has a top speed of 35 knots per hour, which is faster than the original fastest "Fireboat No. 8" at 28 knots. It takes about 20 minutes from Central District Fireboat Fire Station to Cheung Chau, and about 30 minutes from Central to Sai Kung. minute.
The range of the two remote-controlled water cannons/bubble cannons on the boat can reach 100 meters, and they can also spray water mist. At the same time, there is a water curtain system. The whole hull of the boat has water pipes for immediate flushing, so that the hull is "surrounded" by water. At present, only the "No. 7 ship" has a water curtain on the whole ship among the fire ships.

Liang Yuyu, Acting Assistant of the Hazardous Substances Accident Support Team, Director of the Fire Department, said that the equipment made the "No. 7 Ship" special in its role in firefighting and sea rescue:
The other fire extinguishing wheels are used to save the fire, and the "No. 7 wheel" can spray water mist between the fire scene and the fire extinguishing wheels, like a cooling barrier to protect other fire extinguishing wheels.
The water curtain protects the "seventh wheel" itself, which can cool down the temperature and wash away toxic substances.
Acting Assistant of the Hazardous Substance Incident Support Team
Chen Ruhai, Assistant Chief of the Fire Department of the Maritime Affairs and Diving Area, pointed out that the two major characteristics of the "No. The other fire-fighting wheels are on the scene for reinforcements, and the seventh wheel can serve as a support function."
Equipped with "remote control lifesaving buoy" and "underwater remote control robot"
The cab of the "No. 7 ship" also has a thermal imaging night vision system and a visual enhancement system, which can increase the visibility of night navigation and search for people who need to be rescued at sea. The 3D sonar system can even search for underwater sunken ships.
Huang Yaoqun, senior fire chief of marine affairs and diving area, pointed out that the screen in the pilothouse can switch to radar or bow camera at any time.
The ship is equipped with a "remote control lifesaving buoy" costing nearly 50,000 yuan and an "underwater remote control robot" worth 1.35 million yuan. The "buoys" are like "remote control water bubbles". The injured go to the boat; the underwater remote control robot can search underwater without the need for frogmen, and it can also detect the underwater environment and facilitate rescue.
Equipped with a system to monitor the air in the cabin to prevent the infiltration of poisonous gas
There is a system in the cabin to maintain clean air and a specific pressure. Chen Ruhai pointed out that the chemical and biological gas and gamma ray monitors on the "No. 7 Ship" are made in Finland, which can monitor whether the cabin air is polluted. The cabin air is filtered and adjusted by air Filtration, combined with a pressurized fan, maintains a positive pressure of about 500 Pascals (Pa) in the cabin, "in this way, it can prevent the inflow of outdoor polluted air."
On the ship, there is an operating room to analyze the air conditions in each room, even control the opening and closing of the door of the room, and monitor the room with closed-circuit television.
The fire service emphasizes that the system is only controlled by director-level personnel, and the privacy of the injured will be protected.
Biochemical rescue facilities decontaminate the wounded
In the event of an oil spill or toxic gas leak accident, the firefighters will transport the injured to the biochemical rescue facility on the ship, distribute decontamination kits for changing clothes and flushing, and then conduct a health check to ensure that the body is not harmed by toxic substances, and then arrange for the injured to go to hospital. Cabin rest.

Assist in transporting confirmed cases from outlying islands during the epidemic
Huo Zhaobang, assistant district chief of marine affairs and diving area, pointed out that the "ship No. 7" has been dispatched for rescue many times so far, including the third-level ship fire off Stonecutters Island in 2021, and the first-level ship fire off Diaozhong Island in Sai Kung in 2022. .
During the epidemic, "Ship No. 7" assisted in transporting COVID-19 patients living in outlying islands to Central, and then transferred to the isolation location. disinfect."

The Fire Services Department appeals to the public to use the ambulance service with caution. About 18% of the emergency cases in the past three days have not arrived in time for firefighting. The 36-hour rescue drill simulates overseas earthquakes. Drones and search and rescue dogs are deployed to increase rescue efficiency. Fire prevention buses tour various districts
