If risks that you may encounter in the workplace fall outside your remit, there are several procedures that can be followed.
Firstly, you can ask more senior or experienced colleagues for help. Even if you do not have a designated medical professional in your workplace, some colleagues will have been trained to carry out duties such as first aid or fire extinguishing. Even for lesser risks, your line manager should be able to assist you in managing these. Alternatively, you could request further external or in-house training so that you are more adequately equipped to deal with the risks associated with your day-to-day work. Most workplaces allow, and indeed must legally give you, a certain number of days of training every year so that you are able to do your job to the best of your ability.
Equally, your line manager may decide that hiring a risk assessor on a full and part-time basis is the best way to manage the risks that cannot be handled by individual staff members.
These risks can also be dealt with by calling in professionals. Professionals can not only help to deal with issues relating to safety, to physical and mental health, and to other risks by working on site, but also by working off site with employees and associates of your company and by making recommendations and giving advice to employees so that you are able to continue implementing and maintaining the same techniques independently even after they have finished their initial work.
Depending on the scale of the risk involved, other professionals, such as lawyers and the police, can also be contacted and their involvement requested.
