Anified laboratory biosafety standard is adopted. Pathogenic microorganisms are managed in a classified manner, and laboratories are managed in a graded manner.

Based on the infectivity of pathogenic microorganisms and the degree of harm to individuals and groups after infection, pathogenic microorganisms are classified into four categories. Among them, Category I and Category II are collectively referred to as highly pathogenic microorganisms, which can cause very serious/serious diseases in humans or animals. According to the biosafety protection level of laboratories, laboratories are divided into Level 1, Level 2, Level 3, and Level 4. Level 1 has the lowest protection level, and Level 4 has the highest protection level.

Biodeconta owns independently developed vaporized hydrogen peroxide equipment. It can vaporize 30% hydrogen peroxide and release it into the decontamination area to kill microorganisms including non - enveloped viruses, mycobacteria, fungal spores, and bacterial spores (the killing log value ≥ 6). It provides customers with overall space decontamination services. The applicable scenarios are as follows:

01 Newly - built pathogenic microorganism laboratories

Before the laboratory is put into use, conduct biological decontamination on the indoor air, floor, experimental bench surface, centrifuge, biosafety cabinet, medicine cabinet, clean bench, high - efficiency filter, incubator, and other environmental and equipment surfaces.

02 Regular Decontamination

Carry out biological decontamination on the core operation area according to the experimental batches to ensure the normal progress of experiments.

03 Emergency Decontamination

In case of pollution caused by the leakage of pathogenic pathogens, properly handle the environmental pollution through fumigation to avoid causing accidents or aggravating and expanding the pollution.

According to the user's purification requirements, Biodeconta's service engineers first conduct an on - site inspection. Then, based on the floor plan provided by the user, a customized biological decontamination plan is offered and implemented as follows:

The user pre - cleans severely dirty surfaces (dust, dirt).

Biodeconta's service engineers provide on - site services. They arrange equipment, chemical indicator cards, and biological indicators according to the decontamination plan.

Confirm the actual temperature and humidity of the area to be purified, and close the HVAC system, doors, and windows. (If the HVAC system cannot be turned off, seal all the air supply and exhaust vents of the air - conditioning system.)

Personnel leave the site. The decontamination program (lasting 3 - 4 hours) is started through the back - end software, and the on - site data is monitored in real - time.

After the decontamination program ends, start ventilation for residue removal or use a catalytic degradation machine to assist in residue removal.

When the indoor hydrogen peroxide concentration drops below 1 ppm, the on - site service engineer recovers the equipment, chemical indicator cards, and biological indicator tablets.

During the decontamination process of Biodeconta, the decontamination effect is jointly monitored by the chemical monitoring method (CI) and the biological monitoring method (BI). The chemical monitoring method uses chemical indicator cards, and the biological monitoring method uses Geobacillus stearothermophilus (ATCC12980) biological indicators. By checking the killing situation of highly resistant spores, it ensures that the decontamination area achieves a disinfection level of log6.
