NR-6 PPE Life Months

NR-6 PPE Conservation Period Calculator

Under Brazil’s Regulatory Norm NR-6, the employer has to hand out Personal Protective Equipment (PPE) at no cost to the worker and set up a replacement schedule that tracks how fast the gear actually wears out. How long a given item lasts comes down to what it is and how hard it gets used. A practical rule of thumb is months = base_useful_life × (8h / daily_hours_use), and the manufacturer’s expiry date always trumps whatever the formula gives you. For reference, latex gloves tend to last about a month under heavy use, safety helmets up to five years from the manufacturing date, safety glasses one to two years, ear plugs around six months when reused, and an FFP2 mask is good for a single shift.

Any PPE sold in Brazil needs a CA (Certificate of Approval) from the Ministry of Labor. That number is stamped on the equipment, so the employer can look up its validity in the federal database. The whole framework rests on Law 6.514/1977 and Ordinance MTb 3.214/1978, which gave rise to every one of the NRs. On top of that, the employer has to train the worker on how to use the gear properly, keep it clean, store it, and swap it out the moment it gets damaged.

Applications

Occupational safety technicians, purchasing departments and SESMT teams lean on this to put together annual PPE budgets, set up periodic deliveries, keep stock rotating and have proof of compliance ready when the Ministry of Labor shows up to inspect or an ISO 45001 audit comes around.

FAQ

Can the worker take PPE home? Only the personal stuff, like boots or uniforms. Collective items and respirators fitted with cartridges stay on site. Either way, cleaning and disinfection are on the employer.

What if the CA has expired? Toss the equipment right away. In the eyes of the law, handing out PPE with an expired CA is the same as not providing any PPE, and that can bring fines plus liability if an accident happens.

Who pays for replacement when damaged? Always the employer. Even if the worker broke it through misuse, the company replaces the PPE first and only then deals with the consequences (extra training, a written warning) through the normal disciplinary channel.
