If you have concerns about the arrangements your employer is able to put in place to protect you, you should discuss with your manager in the first instance, or the Occupational Health Service (if your employer provides one).
You may also benefit from advice from one of the following organisations:
DEFA’s Health and Safety at Work Inspectorate
Manx Industrial Relations Service (MIRS).
MIRS can help both employers and employees and can provide practical and impartial advice on any employment matter.
