Work can be considered a source of health because with it people get a series of positive and healthy aspects for it: salary, physical and mental activity, develop and activate social relationships with other people, increase our self-esteem, etc. 

Nevertheless the work can also cause different damages to the health of the psychic, physical or emotional type, depending on the social and material conditions where it is carried out. 

Although many of us have work and found positive aspects in it, sometimes we feel insecure and we find flaws in our work environment. 

Work Safety is one of the most important aspects of work activity. Work without proper safety measures can lead to serious health problems. In this sense security is often not treated as seriously as it should be; which can lead to serious problems not only for employees but also for employers. 

The performance of certain tasks in the job, can carry with it some risks posed that lead to an accident at work. Depending on the personal and professional characteristics of the worker, the nature of the facilities, equipment and characteristics of the workplace. . We must take steps to improve this situation. In recent years trade unions have made the inclusion of occupational safety issues in most labor Conventions prosper. 

For these reasons, the Governments are pursuing a stricter policy in relation to Work Safety. Statistics show that a large number of labor inspections end up in penalties for breaching security measures. 

The companies should be interested in implementing programs of Occupational Risk Prevention, a set of techniques that allow to avoid the most common accidents that occur in the work. It therefore benefits the company and the worker by minimizing the risks of injuries and illnesses, contributing to safety and well-being at work. 

Work Safety is a preventive technique, not medical, that deals with the study and control of the risks that can give rise to accidents or incidents, in which we differentiate two essential aspects: 

1) Work Safety is intended to avoid accidents / incidents 

2) In order to achieve this goal, Security is based on techniques that have been studied and proven that can prevent this, and in addition to these, there are procedures that apply to companies and followed by workers and middle managers can avoid the materialization of an accident. 

Before proceeding it is necessary to define: Accident: is the one that causes an injury, of any kind, in the worker including the loss of working days. Incident: it causes an alteration in the development of the tasks, even the temporary suspension of the same, but does not cause the worker to leave for more than one day. 

The main objectives of the tasks in security are: 

1. A) Define the existing risks in the workplace. 
2. B) Analyze the nature of the risks and the measures to be taken to neutralize them 
3. c) Correct the situation and make the indicated improvements. 
4. D) Check that the measures are adequate and produce the desired effect. 
5. E) Control the appearance of new risks.
