Right to refuse dangerous work in Brazil: stopping in serious danger
Published · Updated
Workers may stop an activity when there is serious and imminent risk to life or health, informing their supervisor (NR-1). How to use this right without being punished.
Yes. NR-1, Brazil's general occupational safety and health standard, gives workers the right to stop an activity when, based on their training and experience, they find serious and imminent risk to their own or others' life and health, informing their supervisor immediately. The employer cannot demand a return to work until the risk is controlled.
Quick summary
- When: serious and imminent risk, such as no fall protection, electric shock, gas or unguarded machinery.
- How: stop, inform the supervisor immediately and put it in writing.
- Return: only after the problem is fixed.
- Punishment: a legitimate refusal cannot lead to a warning, pay deduction or dismissal.
- Inspection: labor inspectors can shut down a site or a machine (CLT, art. 161).
How to use the right
- Stop the activity and move away from the risk.
- Tell your supervisor immediately, preferably by message or email.
- Explain the risk and what is missing (PPE, collective protection, energy lockout).
- If there is a CIPA, inform the representative.
- If the employer insists, report it to the Ministry of Labor.
Other guarantees
- The employer must provide suitable, free PPE (NR-6).
- Serious breach of safety rules by the employer may justify constructive dismissal (CLT, art. 483, "c").
- An accident caused by lack of protection leads to job security and compensation.
