Brazil's NR-17 Rulebook: When a Desk Assessment Is No Longer Enough

Companies that treat ergonomics as a one-off audit are missing what Brazil's workplace safety rules actually demand. Under the country's NR-17 ergonomics standard, findings from an initial screening must feed directly into the employer's risk management programme (PGR), while NR-1 adds binding deadlines, ongoing monitoring and measurement of results, as reported by globo.com on 03.11.2026.

Two instruments sit at the centre of the framework: the preliminary ergonomic assessment (AEP) and the more detailed ergonomic workplace analysis (AET).

Screening first, deep dive only when triggered

An AEP can be qualitative, semi-quantitative, quantitative or a combination, and is folded straight into the general risk assessment. Its results go into the risk inventory; the resulting actions are logged in an action plan.

The same principle applies wherever you document workplace risks: a screening is only as good as the paperwork behind it. If your risk assessments are scattered or out of date, a free toolkit gives you 41 ready-to-use templates and checklists to keep your records compliant and audit-ready.

The AET goes considerably further. It covers a needs assessment, examination of organisation, processes and tasks, justification of the methodology chosen, a substantiated diagnosis and concrete recommendations. Workers take part through a feedback, validation and revision stage, and the final report must be kept for 20 years.

Small and micro enterprises — ME, EPP at risk levels 1 and 2, and MEI — are generally exempt from the AET requirement. Exceptions apply where signals from occupational health monitoring or concrete accident and illness analyses make the deeper study necessary.

Four situations that make an AET mandatory

NR-17, item 17.3.2, sets out when a full analysis cannot be avoided. It is required if the preliminary assessment fails to explain a situation adequately, if existing protective measures remain ineffective, if company medical data point to a need for closer examination, or if accidents or illnesses can be traced back to working conditions. A fresh review is also foreseen whenever processes, organisation, technology or legislation change.

Seven steps, six criteria

To steer ergonomic measures efficiently, a seven-stage sequence — running from precise problem definition through to final validation — structures how interventions are planned. When deciding how urgent individual projects are, companies lean on six priority criteria:

• the scale and severity of the identified risk,
• the number of affected workers and their particular vulnerability,
• documented evidence of harm already suffered,
• legal obligations and fixed deadlines,
• the potential to eliminate or reduce the hazard at source,
• practical and technical feasibility.

Measuring what changed, not what was intended

A declaration of intent is not enough to verify measures properly. Specialists recommend three separate indicator levels for systematic impact measurement: parameters covering actual implementation, metrics on changed exposure or process flows, and indicators for the final overall outcome.

When processes, technology or legislation change, your safety documentation has to keep pace — and gaps are where employers become legally exposed. A free toolkit bundles risk assessments, checklists and a directors' liability guide to help you stay compliant as your workplace evolves. Get the free Health & Safety at Work Act 1974 Toolkit

Baseline and target must always remain methodologically comparable. Blanket goals often prove unsuitable in practice — aiming to bring pain down to zero, for instance, is regarded as of little use. Defining concrete exposure limits is seen as far more precise and measurable, such as reducing working time spent with the arms held above shoulder height.
