You should first of all discuss your concerns with your employer or immediate manager. Your company may have a safety representative, who might be your first point of contact. If you have an employee representative, such as a trade union official, they may be able to help you.

Your employer must not expose you to avoidable risks at work; if you've raised concerns about risks in the workplace and not received a satisfactory answer, you can get confidential information from the HSE's Info Line (open 8.00 am to 6.00 pm, Monday to Friday).

As a last resort, you can get in touch with the authority responsible for enforcing health and safety in your workplace (either the HSE or your local authority). Health and safety inspectors have powers to enforce the law.

If you take this course of action, your employer must not discipline you or put you at a disadvantage in your job (for example, by not paying you for the time you refused to work because of unsafe conditions, passing you over for promotion, etc).
