88) Outline the practical measures that might be taken to reduce the risk of violence to reduce the risk of violence to employees who deal with members of the public as part of their work.

 With many occupations exposed to the risk of violence from members of the public, particularly in the service industries, there was a wide range of practical measures that could have been outlined. Better answer looked at measures that encompassed the broad aspect of the environment, job factors, individual protection and general security. Only by addressing a wide range of issues, rather than concentrating on just physical security measures for instance, could high ,marks be obtained.

 The design of the public areas, in terms of d├ęcor, seating, the means of providing information (i.e. on waiting times) and the absence of obvious barriers, can help to reduce the build-up of confrontation and violent episodes. A balance must be drawn, however, between presenting a calm and ‘open’ environment and protecting staff from any violent incidents that could arise. Hence, there will often be need for wide counters, coded locks on doors, CCTV systems, panic buttons and alarm systems, whether these are made discrete or obvious will depend on the particularly those involving money may mean that the risk is too great to avoid the use of some sort of physical means of separation, such as security screens, between employees and the public.

 Many occupations, such as estate consultant/agents and social workers, involve interaction with the public outside work premises. In these cases, measures such as the avoidance of carrying large amount of cash, implementing appointment systems, Client risk assessment and accurate records, keeping may need to be considered. The risk of lone workers should give particular attention, with the need in certain circumstances to avoid lone working altogether and/or to implement regular checks-in procedures and to issue personal panic alarms.

In addition to designing the work place and the task to minimize the risk of violence assault, staff will need to be trained in the procedures and possibly in how they might recognize the early signs of aggressive behavior and avoid, defense or otherwise deal with a violent situations, in certain circumstances, the employment of security staff and the provision of PPE (e.g. bullet or stab proof vests, helmet etc).may be required.

In general, answers tended to be limited, sometimes because candidates seemed to have only one situation in mind, such that faced by health service workers. Others refereed in vague terms to measures such as the need for stringent security but without giving any details or examples of what this might mean.
