6.4(4.1) Work safely in accordance with own level of competence, relevant instructions and legal requirements, following environmentally friendly practices
In the workplace, everyone should be responsible for their own health and safety when they can. If there are situations in which I don’t have a lot of information (pulling out cables / handing electrical equipment), it is best to leave it, create a risk assessment and then wait for someone who does have the knowledge needed to complete the task.

Once you have begun your employment, hopefully you will have been taught the basics thoroughly. If asked to complete a task that you have not yet been educated in or shown, then it is not your position to complete that task as you will not be able to complete it competently, and will probably make quite a few mistakes along the way!

When working, you should always conform to any instructions or legal requirements that have been given to you, ensuring that you are working in a sensible and safe manner, and if you do make any mistakes, at least you were following the instructions that were given. 
Many companies, (including mine) normally give a ‘starter pack’ or guide. This is very useful for new employees as it can work as something to fall back on if no one is around and you are stuck. It is also useful as you are able to almost familiarize yourself with any software, websites or important information given that you are supposed to follow.
