    The purpose of this research work was to develop a technical management plan for mechanical risks for the machining area of the company GT Rectificadora, which sought to strengthen current safety conditions and reduce the exposure of workers to mechanical hazards. The research was carried out due to the presence of unsafe conditions during machinery operation, exposure to rotating systems, and the use of cutting tools during the grinding process. To analyze the current situation of the company, a checklist was applied whose regulations were based on questionnaires provided by the INSST, where 3 categories were evaluated: tools, machinery and the work environment, where the results reflected a 60% non-compliance in tool criteria, 71% in machinery and 100% in work environment, highlighting mainly the non-compliance in the machinery category due to the absence of physical guards, maintenance and safe procedures. For the estimation and evaluation of risk, methodologies such as GTC-45 and William T. Fine were used, which showed the presence of high criticality risk, such as impacts, cuts, entrapment, and projection of particles in grinding, turning, and honing operations. Thus, a management plan to prevent mechanical risks was proposed, incorporating engineering, administrative, and PPE controls for the identified risk to prevent accidents in the work area.

    Currently, protecting the health of workers is not a luxury, but an obligation that must be constantly observed and controlled, therefore, this research aims to conduct an analysis of occupational hazards, having as a priority the mechanical risks of the production area of the company. M&M PLASTICOTOPAXI, being a manufacturing company dedicated to the manufacture of plastic covers, which does not have a technical management of occupational risks and by carrying out processes that involve the use of industrial machines, is continuously exposed to accidents and incidents that put the lives of its collaborators at risk. In order to know the current situation of the company, information gathering tools were used, such as interviews, surveys, observation sheets and information gathering sheets for each work center, where it was determined that it does not comply with certain legal safety requirements. The PGV (Probability, Severity, Vulnerability) method was used to identify hazards and estimate risks, resulting in a total of 328 estimated risks, of which 15 are intolerable risks, since they present a critical situation and require urgent corrections; there are also 150 major risks that need to be managed with control procedures and 163 moderate risks. The NTP 330 Method was applied in order to assess the risks, this allowed to know their level, i.e., from level I which urgently need to be corrected, to level IV of lesser importance that do not need to be intervened. Finally, a safety plan was drawn up to implement and integrate accident prevention within the company, establishing the objectives, policies, responsibilities of personnel within the organization, risk assessments, preventive planning and procedures, which will help minimize the potential risks to which workers are exposed.

    The present investigation work was developed in Davmotor factory, a place located in Tungurahua, specifically at 15 Km in North Pan-American highway in Ambato city, this company is dedicated to the manufacturing and construction of vehicle bodyworks. This study is based on mechanical risks management, since insecure work conditions are related to the operation of equipment, machines and tools, which could generate a source of danger with a huge potential to generate damages in human resources health. The risk analysis is predicated in the identification of sources of risks and a risk estimation, thus the first one was held through the application of ART sheets that is based on analysis of the activities in 12 workstations and the identification of 18 mechanical risk factors, while, in order to get the risk estimation the author used the methodology on the Criteria Matrix PGV, that determinates quantitatively, on probability, gravity and vulnerably terms if the categorized risk is a moderate, important or an inadmissible risk. Finally, the mechanic risk valuation was done by Willian Fine methodology, which determinate in a quantitative way the degree of danger based on the product of probabilistic variables, such as: a consequence level, probability and exposition. According to this study, on the 12 workstations evaluated, a total of 90 risk factors were identified, whose 44 were tagged as moderated and a GP value smaller than 85, while 24 are important risks with a GP value biggest than 85 and smaller than 200, 22 are inadmissible risks with a GP biggest than 200, the last ones are presented in the operative process only, and those are related with the equipment, machines and tools management, that is why to get the risk control a preventive action is proposed which is based on the risk instruction and the prevention methods through a secure procedure manual.
