In the case of preventative disinfection of veterinary facilities, a 0.5% solution shall be used 2 at a consumption rate of 0.25 L/m and exposition time of 3 hours. In the case of emergency (current and final) disinfection of veterinary facilities, a 1.0% solution shall be used at a consumption rate of 0.5 L/m² and a 24-hour exposition.
The consumption rate shall be increased to 0.6 L/m² and the work solution shall be applied twice (at a dose of 0.3 L/m²) with a 60-minute interval when elements to be watered or wiped are made of porous materials (undyed wood, cement, rubber).
Preventative and emergency disinfection of feed boxes, drinking pans, and other removable equipment of animal breeding facilities is carried out by their immersion in a 0.5% GAN solution. The solution is used in a 2:1 “solution—material to be cleaned” ratio. Materials shall be exposed to the solution for 1 to 2 hours depending on the type of disinfection. After disinfection, feed boxes, drinking pans, and equipment shall be washed with warm water; then, facilities shall be ventilated and dried.
In case of especially dangerous infectious diseases, it is recommended a one-time treatment by spraying a 2% GAN working solution at a rate of 0.5 L/ m² with a 6-hour exposure or a 4% GAN working solution at a rate of 0.3 L/m² and an hour (minimum) exposure.
Disinfection (preventive or forced) by aerosol spraying of a GAN working solution (as mist) is carried out at disactivated ventilation with fog generator or other similar equipment. A working solution for aerosol disinfection is prepared by dilution of the agent at a 1:2 GAN - water ratio (thus obtaining a 10% solution). The prepared working solution is to be used 3 during the day at a rate of 10 mL/m . The working solution (10%) is to be sprayed, at deactivated ventilation, with a 24-hour exposure.
After aerosol disinfection, feeders, waterers, and equipment should be washed with warm water, premises should be ventilated and dried.
Local disinfection of individual animals (not enclosed in stalls or cages), equipment, tools, and surfaces is possible while providing intensive ventilation and no people and animals present in the immediate vicinity of the processed facilities. For disinfection, a 0.5% working solution is applied by spraying, foam generating, soaking, or wiping the surface. Disinfectant barriers and disinfectant baths are to be filled with a 1% GAN working solution. The disinfection solution shall be replaced as required, but not less than 2 to 3 times a week.
Quality control of disinfection shall be carried out in accordance with the methodology set out in the current state standard in your Country. Sodium bisulfite is used as a 0.1% neutralizing agent solution. GAN is not compatible with anionic surface-active substances (surfactants) and their solutions. To apply GAN working solutions at low temperatures (maximum 20°C), it is recommended to prepare the working solution on the basis of a 30% aqueous solution of ethylene glycol.
