NR12: Essential aspects
According to the standard, all machines and equipment must have an instruction manual that is provided by the manufacturer. It must contain all information regarding safety at all stages of use. It is important to note that this manual must also follow the requirements as described in the NR12 standard. If the manual is lost or inexistent, it must be reconstituted by the employer, following the guidelines of a legally qualified professional.
All work carried out must have a specific, standardized performance and safety procedure, with a detailed description of each task in accordance with the standard. It is necessary to carry out routine inspections of the operational and safety conditions at each start of the work shift, or after a new preparation of the machine or equipment.
Following the norm, all operations, maintenance, inspections, and other services in machinery and equipment must be performed only by trained, qualified, qualified or authorized professionals to perform that specific function. Therefore, it is under the full responsibility of that employer to promote training compatible with the role that each employee will perform. This training must also follow a standard as described in the standard.
To be considered a qualified professional, it is necessary to prove the completion of the course in this specific area of expertise. This course must also follow all procedures described in the standard. Generally, the training course has a minimum load of 8 hours per machine type which is mentioned in annex IX of the NR12 standard.
The NR12 standard has several additional information regarding different types of machines and procedures described through figures, tables, and texts in the annexes. We cannot fail to mention that it is the employer’s full responsibility to keep the inventory of machines and equipment always up to date with identification by type, capacity, security systems, in addition to the location on the floor plan.
Now that you know the importance of NR12, it is necessary to go deeper in each point and understand that each item can be fundamental to allow an adequate and safe work environment.
