what is the different between NR 12 (Norma Regulamentadora 12) and NR 10 (Norma Regulamentadora 10)?

NR 10 (Norma Regulamentadora 10) and NR 12 (Norma Regulamentadora 12) are both regulatory standards established by the Brazilian Ministry of Labor and Employment (Ministério do Trabalho e Emprego) to ensure safe working conditions, but they address different aspects of workplace safety:

NR 10 (Norma Regulamentadora 10):

Focuses on safety in electrical installations and services.

Specifies guidelines, procedures, and safety measures to prevent electrical accidents in workplaces.

Covers aspects such as installation, operation, maintenance, and inspection of electrical systems and equipment.

Aims to protect workers from electrical hazards and ensure that electrical installations are carried out safely.

Key areas of concern include risk assessment, grounding, insulation, electrical protection devices, training, and documentation related to electrical safety.

NR 12 (Norma Regulamentadora 12):

Focuses on machinery and equipment safety.

Specifies requirements for the design, construction, installation, operation, and maintenance of machinery and equipment used in workplaces.

Addresses mechanical hazards such as crushing, cutting, shearing, and entanglement.

Requires the implementation of guards, protective devices, safety features, and ergonomic design principles to prevent accidents related to machinery.

Emphasizes risk assessment, guarding, emergency stop systems, ergonomics, controls, safe work procedures, documentation, and maintenance related to machinery safety.

In summary, while NR 10 primarily deals with electrical safety in workplaces, NR 12 focuses on mechanical hazards associated with machinery and equipment. Both standards aim to protect workers from different types of workplace hazards and ensure compliance with safety regulations to create a safe working environment. Depending on the nature of the workplace and the types of hazards present, companies may need to comply with one or both of these standards to ensure comprehensive workplace safety.
