Mark Webber admits to having serious reservations about the new KERS system after a BMW mechanic was shocked.

During last month’s Jerez test, a BMW mechanic staff was rushed to hospital after suffering a shock from a car fitted with the Kinetic Energy Recovery System.

This marked the second such incident after Red Bull’s factory headquarters had to be evacuated due to the smoke pouring from a battery.

However, the case involving BMW was of even greater seriousness and the team’s failure to come up an answer after investigation has left a huge impression on Webber.

"There is a report coming from BMW about what happened there, but the rumour is they haven't a clue why it happened. They have no idea - and that is a worry," Webber told Autosport.

"You only need to think about what would happen if someone gets shocked into the fast lane of the pit lane.

"It is like a plane crash when you don't get the evidence."

Force India tech boss Mike Gascoyne, however, played down the Australian’s fears, saying: "It's the flavour of the month but the simple fact is teams will get on top of it.”

"If you look at the electronic systems, they are fairly standard technology which is why people are going for them rather than some of the more involved mechanical type systems that do pose a lot of problems.

"The fact is, we will get on top of them quickly. As soon as one person does, the nature of Formula One means everyone else has to. Things like the incident with BMW, I'm sure they are working to understand it, but I don't think that'll cause problems. It should be straightforward.

"Certainly the electronic KERS we're looking at is a fully sealed unit. All the high-tension cables are within a sealed unit. It's difficult to see how you can have a problem."
