ISO 45001 consulting and internal audit in Puebla

A typical project takes 6 to 9 months: about three to assess, evaluate risks and document, and the rest to operate the system, audit it and gather the evidence the certification body asks for. A company that already complies well with the STPS standards, or that holds ISO 9001, moves faster.

Safety and sustainability are part of automotive supplier assessments, and more and more questionnaires ask for a certified occupational health and safety system. ISO 45001 integrates well with IATF 16949 and ISO 14001, which many suppliers already hold.

No. It is a voluntary standard; what is mandatory are the STPS NOM standards and the Federal Labor Law. In practice customers, head offices and supply chains require it —especially automotive, construction, mining and energy— and it helps organize legal compliance.

ISO 45001 replaced OHSAS 18001, which stopped being valid in 2021. It adds the context of the organization, top management leadership, consultation and participation of workers, contractor control and the common structure shared with ISO 9001 and 14001.

It depends on the number of workplaces and people, the risk level of your processes and what you already have in place. That is why every proposal includes three scope options at a fixed price, starting from a free assessment. Certification body fees are quoted separately.

No: certification is granted by an accredited certification body, independent from the consultant. We implement, audit internally and accompany you through the certification audit and the closing of findings.

The standard is under revision and publication is expected in 2027, with more weight on mental health, psychosocial risks and hybrid work. Implementing ISO 45001:2018 today is not wasted work: certified systems will get a transition period, and those already managing NOM-035 start ahead.
