Course of Interpretation and Applying of NR 12
The ultimate goal of the Course of Interpretation and Applying of NR 12 consists in define techniques references, fundamental principles and protective measures to ensure health and physical integrity of the workers according to the NR 12, which sets the minimum requirements for prevention of accidents and work diseases.
What is the NR-12?
The Regulatory Standards approaches the projects phases and utilizations of machines and equipments, plus it’s own fabrication, importation, commercialization, exposition and cession to any title and economical activity, without the prejudice compliance quoted on the others Regulatory Standards and technical standards and, in case of their absence or omission, the international standards applicable.

Legal Basis – Technical Standard 54 Work Ministery
RESPONSABILITIES – As a capacitation in SST it’s a labor obligation to be given by the employer to their employers in reason of risks arising from the explored activity, it’s full responsibility of the employer guarantee your effective implementation, subjecting to appropriate administrative sanctions in case of a not effective capacitation or still for a rottenness which doesn’t attend to legislation requirement’s. It’s indispensable to observe that, even if opt for the training realization in SST by distance or blench, it’s salutary that all training is adapted to the reality of each establishment. The employer is being capacitated by the employer to operate in a determined space, so, a generic capacitation will not attend to the peculiarities of every and any economical activity. See the Technical Note 54 of the Ministry of Labor MT.
PDCA Cycle (Plan-Do-Check-Act)
The OH&S management system approach applied in this document is based on the Plan-Do-Check-Act (PDCA) concept.
The PDCA concept is an iterative process used by organizations to achieve continuous improvement. It can be applied to a management system and each of its individual elements, as follows:
a) Plan: determine and assess SSO risks, SSO opportunities, other risks and other opportunities, establish the SSO objectives and processes necessary to ensure results in accordance with the organization’s SSO policy;
b) To: implement the processes as planned;
c) Check: monitor and measure activities and processes in relation to the OH&S policy and OH&S objectives and report the results;
d) Act: take measures for continuous improvement of OH&S performance, to achieve the intended results.

Interested Party (Stakeholder): Person or organization that can affect, be affected or perceive themselves to be affected by a decision or activity.
The justification of the Price and Value relationship:
The pricing of any service requires expertise related to the business world and the concept of Value is qualitative, directly linked to the potential for transformation existing in that content. The service has more value when it has added professional knowledge and secrets and the price is a consequent variable of the value, whose objective is to transmit it in numbers. Thus, the greater the value added to the content, the greater its fair price. Therefore, we do not authorize the use of our Proposals as counter-proof of closing with third parties of a lower price, or of secondary interest, Quality, Safety, Efficiency and Excellence, in every way, are our values.
Causes of Work Accident:
Lack of notice from the employer;
Lack of employee care;
Even carrying out all Training and mandatory Occupational Health and Safety Reports in the event of an accident at work, the employer will be subject to Processes such as:
Police Inquiry – Civil Police;
Expertise through the Criminal Institute;
Investigation Procedure at the Regional Labor Office;
Public Civil Inquiry before the Public Ministry of Labor to verify that other workers are not in danger;
The INSS will question the cause of the accident that could have been avoided and refuse to pay the benefit to the employee;
Family members may file a lawsuit in the Labor Court claiming Moral, Material, Dislocation, etc.;
Procedural Tsunami forcing the Employer to generate Defense Strategy even though it is right;
Although the Labor Delegation Law does not provide that the “culpa en vigilando” applies, but only the responsibility to deliver the equipment, but it is worth emphasizing that the Employer is also responsible for monitoring;
When an accident occurs, in addition to destroying all the “good mood” in the relationships between employees or also the very serious problem of defending yourself from a series of procedures at the same time, then it is worth investing in this prevention;
The Employee may not carry out activities exposed to risks that may compromise his safety and health, so the Employer may respond in the criminal and civil spheres.
