BMW-Sauber on Thursday insisted there was no danger to either the mechanic or test driver Christian Klien during the electric shock incident at the Jerez test a month ago.

The unnamed mechanic was thrown to the ground and then hospitalised, but not seriously injured, as he tried to wheel Klien's prototype test car, equipped with an early KERS system, at the Spanish circuit.

But while conceding that high voltage was involved, the team's head of powertrain Markus Duesmann denies that the mechanic or Klien were exposed to serious danger.

"No (there was no serious danger), as only a small amount of energy can be transferred through this capacitive coupling effect," Duesmann said in a statement. "However, the energy is sufficient to cause an extremely painful reaction."

At the end of a long investigation into the incident, BMW also said Klien was protected by the shock by his racing overalls and gloves.
