One in four workers in London have slipped or tripped at work in the last year, according to a report by the Health and Safety Executive (HSE).
Slips and trips are the biggest cause of injury, says the HSE
It is launching a Watch Your Step campaign to highlight the impact of workplace injuries on both the employee and businesses.
The HSE reports that these injuries are on the increase and last year cost UK companies more than £500m.
It is providing tips on how to minimise such accidents.
There were more than 40,000 recorded slipping or tripping accidents last year, making them the most common cause of workplace injury.
It amounts to one injury in every three minutes, according to the HSE report, and every hour someone breaks a bone.
"Slips and trips are the biggest cause of major injury at work in Britain today," says Justin McCracken, HSE acting chief executive.
"We estimate that they cost the UK economy about £800m each year, and preventing them isn't difficult or expensive.
"If you see a spill or if you see something lying around, clear it up," he said.
"Our message is - if you see a problem, don't just see it, sort it."
He advised employers to make sure lighting was satisfactory, floors were clear of obstacles such as cables and that spillages were cleared up.
