If you work with equipment or machinery, your employer has a duty to train you and ensure that the equipment is safe and properly maintained. If you are injured during your work, you may have a claim, even though you thought the accident was your fault. You can also suffer illness as a result of inhaling toxic fumes or coming into contact with dangerous substances. If you are injured or made ill by your work you should certainly consider claiming. Normally your employer will be insured, so any compensation will come from an insurance company.
