One man remained in hospital for observation and was expected to be released in the next few hours, while the other had returned to work, The Hobbit unit publicist Ceris Price said:

The incident happened in one of the workshops when “a couple of the guys” were drilling a statue, Ms Price said earlier today.
The pair were left with “mild burns but nothing serious” and were taken to hospital as a precaution, she said.

“One of them had some burnt nostril hairs and, apparently if that’s the case, there is always the risk of inhalation so they get checked out.”

She said calling the incident an explosion was a “slight overstatement” and no fire was caused by the incident.
