Activities covered
NR-36 applies to organisations slaughtering and processing meat and derivatives intended for human consumption. Its scope does not automatically extend to every food-related activity. The regulation connects workstation conditions, equipment and organisation with harm prevention. Assessment must distinguish animal reception, line operations, cleaning, maintenance and other process tasks.
Workstations and tools
The text addresses dimensions, work surfaces, reach, postures, platforms, product handling, equipment and tools. A suitable tool also needs maintenance and conditions of use compatible with the task. Observing an empty workstation alone can miss how products, access to materials and required force vary during a demanding part of the shift.
Timing and work organisation
NR-36 provides for organising time and activities alongside assessment of work situations. Recovery or task-alternation measures must be analysed against the regulation’s specific requirements. Rotating between two tasks with very similar demands does not demonstrate reduced load. Nor can a break be assumed to compensate for any pace or design deficiency.
Integrating risks
These activities may combine cold, noise, cuts, biological exposure, cleaning products and physical demands. The PGR and PCMSO must receive consistent information about conditions. Resolving one risk may change another: changing gloves, for example, requires checking grip and dexterity as well as protection. Decisions must be assessed together and with participation by the people performing the task.
Example of improving an operation
Suppose difficulties emerge in a manual cutting operation. The analysis may examine height, reach, tool condition, product variation and line organisation. Before concluding that training is lacking, check whether the task allows the intended technique to be used. The example does not prescribe a universal ergonomic solution; it provides a route for distinguishing physical and organisational causes.
How to verify a measure
After introducing changes, observe different periods and collect information about difficulties in use. Incident, maintenance and collective health records may provide signals while respecting confidentiality. The ergonomics entry explains the adaptation approach, but NR-36 contains sector-specific Brazilian requirements. Compliance must be examined against its official text and related regulations; a food-hygiene audit does not replace worker safety and health assessment.
