Businesses that employ children during the summer holidays have been reminded they need to comply with health and safety legislation.
According to Paul Butler of East Riding Council, the authority takes the safety of youngsters in the workplace very seriously.
As a result, he has called on firms that have taken on pupils for the extended summer break to ensure they are complying with the law.
This means they need to have the necessary permits in place that guarantee 13 to 16-year-olds are protected by employers' liability insurance.
"Where they do not act responsibly, then we are prepared to take legal action and this could result in a court appearance," Mr Butler commented.
He added that companies could be fined up to £1,000 if they are found to have breached the rules.
East Riding Council is carrying out spot checks throughout the summer in order to see whether the law is being obeyed.
According to figures from the Health and Safety Executive, 54 under-18s died in a workplace accident between 1996 and 2001.
