Cattle deaths

Some 10 prize bullocks died in quick succession whilst housed over winter in a cattle shed. The government vet was unable to reach a conclusion on cause but apparently does not discount electric shock as an indirect cause.

The shed comprises steel columns and trusses with corrugated iron sheeting over. The floor comprises re-Inforced concrete slats over the slurry tank. The pens have steel barriers supported by steel posts all of which are heavily corroded but still making contact with other albeit fortuitously.

The earthing system is TT with the shed steelwork on its own providing a substantially low impedance of 5 ohms using a loop tester. A 100mA RCD protects the rather ropey lighting circuits.

whilst the floor could be wet, I can’t conceive how a voltage difference could be established even if the steelwork was at 230v

As a one time cadet, the wisdom of the time (if outdoors in a lightning storm) was to get down, curl up and try to cover your head - the old hands used to do this - we were then told to adopt the "lightning crouch" to minimise ground contact whilst still keeping low

It was like a bloody stress position
