Electrical Safety in Agricultural Facilities and Farms

IEC 60364-7-705 Standard Technical Guidance

Livestock farms and agricultural warehouses are humid and corrosive working environments where animals are far more sensitive to stress than humans. How should dangerous step voltages in animal living spaces be reported and reset?


AES Innovation

A Permanently Wet Facility: Risk of Loss of Livestock and Capital.

Conditions in agricultural and horticultural facilities (greenhouses, barns, poultry farms) are vastly different from those in a factory environment. At AES Innovation, we inspect the safety of biological assets (animals) in agricultural areas and the fire safety of automation panels in product storage facilities according to the specific regulatory criteria IEC 60364-7-705, and prepare compliance reports.


While the human body can tolerate voltages up to 50 volts, the step voltage capacity of, for example, beef cattle, due to their ability to stand on all fours, is only 25 volts. Even a smaller electrical leak can lead to reduced production, stress, or mass animal death. Wet manure cleaning necessitates sodium-based or IP55 minimum liquid protection in luminaires.

Electrical Risk Analysis in Barns and Poultry Houses

  • Specific Animal Step Tension – Equipotential Bond:
    The feed machines, water troughs, and floor profile frame in the barn are tested and verified to have a complete ground connection using high current (impedance) measurements.
  • Fire and Life Protection 300mA / 30mA Functions:
    For installation protection in the production panel. Limits of <300 mA (haystack fire prevention) and <30 mA for live insulation in socket lines are analyzed via RCD response speed.
  • Analysis of Low Step (Touch) Voltage SELV:
    Specifically, it is documented that milking machines maintain a maximum voltage limit of AC 25 V or DC 60 V in non-human contact situations.
  • Mechanical Stress, Heaters and IP Sealing:
    Thermal heating bulbs (infrared/radiant heaters) and suspended cables exposed to fertilizer gases (ammonia, etc.) are inspected in terms of insulation and IP54/IP55 barrier rating in the physical environment.
WHY AES INNOVATION?

There is no tolerance for accidents in animal production.

If a short circuit in your greenhouse's water pump triggers a lightning reaction, or a wet feed line in your barn constantly shocks the animals, then the survival of the organic and physical structure there is at risk. AES Innovation, By implementing the IEC 60364-7-705 inspection process, reinforced by agricultural insurance and modern standards, we ensure that your rural infrastructure operates without production losses.

Frequently Asked Questions

Frequently asked safety questions about agricultural cooperatives, milking stations, or greenhouse businesses.

While the maximum permissible contact voltage for humans is AC 50V, according to the IEC standard, this figure is defined as a maximum of AC 25V for hospice animals such as cows.

The minimum protection level for luminaires, motors, and switchgear should be designed with corrosion resistance ratings ranging from IP54 to at least IP55 due to the presence of sulfuric or fertilizer dust.

In buildings that store hay and straw, the lighting surfaces of the fixtures must have an insulation casing and a fully dust-proof glass layer (IP5X) to protect against the high risk of the fixture burning out.

A cow, its neck tied to the concrete by its ear tag and chain, touches the rebar, and its feet touch the wet mat on the ground. The perfectly coupled equipotential bar between the rebar and the trough holder eliminates the voltage potential.
