Under common law [Health and Safety at Work Act 1974], employers must take reasonable care to protect their employees from the risks of foreseeable injury, disease or death at work and/or damage to their property.
If an employer is aware of a health and safety risk to employees or in the light of current knowledge at that time, to have known of the existence of a hazard, he will be liable if an employee is injured or killed or suffers illness as a result of the risk, or if the employer failed to take reasonable care to avoid this happening.
The common law duties require that all employers provide and maintain:
These duties apply even though an employee may be working on a third party's premises or where an employee has been hired out to another employer, but where the control of the task still lies with the permanent employer.
