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 purification 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 purification services. The applicable scenarios are as follows:
01 Newly - built pathogenic microorganism laboratories
Before the laboratory is put into use, conduct biological purification 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 purification
Carry out biological purification on the core operation area according to the experimental batches to ensure the normal progress of experiments.
03 Emergency purification
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 purification 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 purification 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 purification program (lasting 4 - 6 hours) is started through the back - end software, and the on - site data is monitored in real - time.

After the purification 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.

Confirm the color change of the chemical indicator cards and the culture results of the biological indicators (after 2 - 7 days).

Issue a verification report.

During the sterilization process of Biodeconta, the purification 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 purification area achieves a disinfection level of log6.
