NR-33: Entry Permit That Survives Audits

The Regulatory Standard 33 (NR-33) establishes guidelines for safety and health at work in confined spaces, promoting the protection of workers who perform activities in environments where access and ventilation are limited. One of the main requirements of this standard is the preparation and retention of the Work Permit (PT) for entry into these spaces. Despite its importance, many managers still make classic mistakes in filling out and managing this document, which can result in serious consequences during audits.

Error in Filling Out the Work Permit

One of the most common mistakes is the lack of crucial information when filling out the PT. Each field of the permit must be carefully completed, as the absence of data can compromise the safety of the operation. Examples of information that should not be overlooked include:

• Identification of the work area: It is essential to specify the exact location where the activity will be carried out, avoiding ambiguities that may cause confusion.
• Description of the activity: Detailing the task to be performed in the confined space helps to understand the associated risks.
• Necessary personal protective equipment (PPE): Listing all PPE that must be used is essential to ensure worker safety.

For example, in a petrochemical industry in São Paulo, the lack of a clear description of the activity led to a situation where workers were not adequately prepared for the associated risks, resulting in an unfavorable audit.

Inadequate Retention of Documents

NR-33 requires that the Work Permit be retained for a specific period after the activity is completed. A recurring mistake is the premature elimination of these documents. Inadequate retention can result in legal issues and difficulties in future audits. Companies must have clear policies regarding the storage of the PT, including:

• Retention period: The standard recommends that the permit be kept for a minimum of 5 years, especially in cases where there have been incidents or near-misses.
• Organization of documents: Maintaining an efficient filing system that allows easy access and consultation is crucial. The use of technology for digitization and cloud storage can facilitate this process.

A practical example occurred in a food factory in Paraná, where the elimination of PTs before the legal deadline led to the loss of crucial information for analyzing an accident that occurred years later. This not only complicated the investigation of the incident but also resulted in fines and sanctions for the company.

Absence of Periodic Review and Update

Another common mistake is the lack of review and update of the Work Permit. NR-33 requires that the permit be reviewed whenever there are changes in the conditions of the confined space, such as modifications in the environment or the risks involved. The absence of this practice can lead to a false sense of security and risky situations. To avoid this problem, consider the following practices:

1. Conduct periodic audits to verify the compliance of the PTs with the current conditions of the space.
2. Implement a feedback process where workers can report unsafe conditions that may require a review of the permit.

A construction company in Rio de Janeiro faced serious consequences due to the lack of updates in the PT, resulting in a workplace accident that could have been avoided. Constantly reviewing permits is crucial to ensure the ongoing safety of workers.

When to Seek a Specialist

If your company is facing difficulties in preparing or retaining the Work Permit in accordance with NR-33, it is advisable to seek the help of a workplace safety specialist. Qualified professionals can help identify flaws in the process, provide adequate training to employees, and assist in implementing best practices. Additionally, they can provide support during audits, ensuring that all documents comply with legal requirements.

Checklist to Ensure Compliance with NR-33

To help your company maintain compliance with NR-33, consider following this simple checklist:

• Check if all work permits are properly filled out with the necessary information.
• Ensure that documents are stored for at least 5 years after the activity is completed.
• Conduct periodic audits and updates on the PTs whenever there are changes in working conditions.
• Train employees on the importance of NR-33 and the correct filling out of the entry permit.
• Consider consulting a specialist to review your processes and documents.

Implementing these practices not only helps your company avoid problems during audits but also ensures a safer and healthier work environment for all employees. Maintaining compliance with NR-33 is a commitment to safety that should be prioritized in any organization. For companies seeking support in this journey, partnerships with specialized consulting firms, such as Legnova, can provide valuable resources to enhance workplace safety processes.
