Businesses are being warned that they face fines and injury compensation claims if they do not conduct risk assessments.
The message follows an incident at a garage in Wales.
Pentre Motors was fined GBP 6,000 and ordered to pay costs of GBP 4,000 following an incident in which a customer’s child fell six feet from a raised vehicle ramp.
The child, who was inside a car which was being inspected for faults, opened the passenger door and fell to the floor of the garage, suffering injuries to her face and teeth which required approximately 30 stitches.
Health and Safety Executive inspector Sarah Baldwin-Jones said Penre Motors had failed to assess the risks associated with allowing children to remain in a vehicle which was being raised from ground level.
"Falls from height often result in serious injury as was the case here and it is for employers to ensure they take all reasonable practicable step to prevent this from happening," she added.
The incident follows a serious work injury in Surrey, in which a construction employee was left paralysed after falling more than three metres onto a concrete floor.
