The fifth wave of the epidemic in Hong Kong has rebounded. The Fire Services Department promotes "precision disinfection" of ambulances and introduces three new disinfection tools. Among them, high-efficiency disinfectant replaces traditional bleach, which kills bacteria in just 5 minutes, saving 15 minutes compared to the past, about seven into time.
The Fire Services Department has also added two disinfection inspection tools to replace the previous visual inspection, including applying fluorescent agent to frequently touched surfaces to conduct surprise inspections to see if disinfection personnel have thoroughly cleaned them, and using ATP bioluminescence reaction detection equipment to collect environmental samples for testing .
The Fire Services Department hopes to protect citizens using ambulance services from infection and reduce the risk of the virus entering the community.

During the peak of the fifth wave of the epidemic, the Fire Services Department received 2,700 ambulance calls in a single day, and 866 ambulancemen were infected or quarantined. Disinfection of vehicles increased sharply from 10% to 90%, and the time required was two to 20% longer than usual. three times.
Diverting ambulances to 42 disinfection stations in Hong Kong
In order to speed up the rotation of ambulances, the Fire Services Department has added 12 disinfection stations to hospitals, fire stations and ambulance stations in Hong Kong since June this year. Currently, 42 stations are in operation to handle new crown cases or suspected cases, especially those that have undergone high-risk procedures such as For the disinfection of ambulances such as throat insertion and atomization, a real-time triage system is also used for prescriptions, and ambulances are arranged to vacant disinfection stations.

Chemical powder coagulates blood for easy cleanup and infection
The new high-efficiency disinfectant introduced by the Fire Services Department can kill most pathogens, including spores, within 5 minutes of contact time, which is about 15 to 30 minutes faster than the previous use of bleach, and an estimated saving of about 15 minutes.
High-efficiency disinfecting wet wipes are added to the ambulance, which can kill 99.99% of bacteria in 10 seconds and the new coronavirus in 30 seconds; the powder in the blood/body fluid leakage treatment kit can quickly absorb liquid moisture and solidify into a gel within 1 minute. Easy to clean up fluids released by the patient.
Introduced UVA testing and ATP instrument unannounced random inspection and disinfection process
The Fire Services Department has also added two types of disinfection and inspection tools, which are coated with fluorescent agent on 10 frequently touched surfaces, such as handrails, bed lifts, handles, doors, seats, etc. When outsourced workers or ambulancemen complete disinfection, use UVA ultraviolet inspection, if there is still residual fluorescent agent in the relevant position, it means that it has not been thoroughly cleaned; as for the ATP bioluminescence reaction detection instrument, the surface sample of the object can be taken and the result can be quickly read within 10 seconds. If the data shows 250 units or more, it means There are also residual contaminants and microorganisms.
Protect citizens from infection and reduce the influx of virus into the community
Ambulance Supervisor (Counselor) Tam Kit Fung said that the Fire Services Department will gradually and fully apply new disinfection tools to protect citizens using ambulance services from infection and reduce the risk of the virus entering the community. About 80 to 100 times a month.
Asked why the tools were introduced after the peak of the epidemic?
Tan Jiefeng emphasized that the prescription has always paid attention to the disinfection tools used around the world, and the Center for Health Protection and medical supervision introduced it after research.
Mo Jialiang, the medical director of the Fire Services Department, said that the new cleaning agent contains chemical substances, which may cause allergies after contact. Therefore, disinfection personnel need to wear gloves, and medical institutions around the world have adopted them. He believes that the public need not worry.
