straight forward health and safty advice 
As far as possible, always cooperate with others, and groups working around you, to try to improve the health and safety of your workplace Everyone should aim to have surroundings that are free of injuries, ill health and loss. You can help to do this by looking out for, and obeying safety signs; and by keeping the area where you are working in a tidy and safe condition. If you are working in an area that is still being used by the other people, whether they are members of the public, fellow workers of the occupiers of the premises where you are working, then you must take measures to protect them. Erecting suitable and adequate warning notices and/or barriers is the best way of doing this. It is important that you don’t undertake any task that may be a risk to yourself, or to others, unless you are sufficiently trained how to do it. Once you are trained you should be able to satisfy an experienced person that you are able to carry out the work safely and efficiently. Where a risk assessment and/or method statement is provided for a work activity, you must make sure that you fully understand it and can comply with its requirements. If this is not the case, and you feel that additional workplace precautions are required to carryout the activity safely, then you must raise your concerns immediately with your supervisor.
