Employers are being warned that they face injury compensation claims if they do not protect against the risks of working in confined spaces.
The warning follows an incident in Wiltshire in which worker Paul Sharp was killed after suffering from heat exhaustion as he undertook cleaning work inside a silo.
Mr Sharp’s employer Silocheck Limited was fined GBP 30,000 and ordered to pay costs of GBP 15,000.
Health and Safety Executive (HSE) inspector Ian Whittles said the tragic incident underlines for need for employers to undertake appropriate training measures and emergency arrangements.
He added: "In this case, there were no appropriate systems of work, particularly with regard to access.
"For example, had there been a winch available, then rescuing Mr Sharp from inside the silo would have been much quicker and easier."
It is the second warning about work in confined spaces in as many months, as the HSE recently launched an investigation into the deaths of two workers at a fish farm near Oban.
