Employers are being reminded to be vigilant about their safety practices after two workers in Mansfield suffered work injuries within weeks of each other.
One suffered a fractured knee in June 2007 when goods from a consignment of lorry wheel assemblies he was unloading fell from a stack.
The next month a stack of tyres fell on top of another employee, causing him to be badly crushed.
SDC Trailers and SDC Parts and Services were fined a total of £5,900 and ordered to pay costs of £1,824.60 after pleading guilty to breaching health and safety legislation.
"The results can be serious for people and for businesses that fail to comply with their health and safety duties," said Health and Safety Executive (HSE) inspector Maureen Kingman.
HSE inspectors recently prosecuted two firms at Chichester crown court after inadequate training tragically led to the deaths of two crane operators in 2005.
