When do I have to comply with health and safety?

Employers must at all timestake reasonable care to protect employees from the risk of injury, disease or death.

Should your company be unfortunate enough to be involved in an accident or dangerous occurence, HSE / Local Authority Enforcement Officers could enter your premises at any time. If your facilties and systems are found not to be up to the required standards you could thereafter be subject to enforced closure of the business, fines, terms of imprisonment and the responsible Company Officer could be debarred and face civil action for negligence.

So the answer to this one is NOW!
