What is the objective of the NR 33 Course – Authorized Worker and Watchman?
The objective of the NR 33 Course – Authorized Worker and Watchman is to technically train professionals to operate safely, responsibly, and in full legal compliance within confined spaces, as required by NR 33. The content prepares both the authorized worker and the watchman to identify atmospheric, physical, and organizational risks, interpret the Entry and Work Permit (PET), properly use safety equipment, and act in a coordinated manner during emergency situations.
Moreover, this course goes beyond simply complying with a regulation, it invites participants to embrace a new level of awareness: to understand that their presence, focus, and internal state directly influence the safety of the operation. Therefore, safety is not just about regulation, it is a state of being.
What is the difference between the roles of the authorized worker and the watchman according to NR 33, during confined space entry?
The authorized worker is someone formally trained and cleared to enter the confined space, perform specific tasks, and use the necessary equipment with responsibility and competence. The watchman remains outside the space, maintaining constant visual or communicative contact, monitoring time spent inside, controlling access, and activating the emergency plan if needed.
In practice, the authorized worker brings the body into the risk zone; the watchman sustains the link between external safety and immediate response. Both are complementary components of the same operational field, one acts, the other safeguards. This synergy only works when mutual respect, trust, and coherence are present.
What are the minimum criteria that must be included in the Entry and Work Permit (PET) before starting confined space activities?
The PET must include:
Identification of the confined space and activity;
Names of the authorized workers and the watchman;
Start and end date and time;
Identified risks and applied control measures;
Available emergency equipment;
Responsible technical personnel;
Defined rescue plan;
Signed authorizations.
Although formal, this document carries technical and ethical weight. It is a contract of trust between life, regulation, and those involved. When filled out with awareness rather than as a formality, it becomes a vibrational shield against negligence.
What equipment is mandatory for continuous atmospheric monitoring in confined spaces?
According to NR 33, multi-gas detectors are required to monitor:
Oxygen deficiency or excess (O₂);
Flammable gases (LEL – Lower Explosive Limit);
Toxic gases such as carbon monoxide (CO) and hydrogen sulfide (H₂S).
These detectors must be calibrated and capable of continuous reading. In some cases, ventilators/exhaust systems, directional ducts, and backup power may be required.
However, the most powerful sensor remains the worker’s active perception: a truly present operator senses the environment beyond the data — they detect subtle changes, recognize patterns, and anticipate danger.
How should the watchman record and document occurrences during confined space operations?
The watchman must document, with accuracy and continuity, all data related to the entry, stay, and exit of workers, including:
Entry and exit times;
Changes in atmospheric conditions;
Communication failures;
Interruptions;
Behavioral or technical observations;
Emergency activations (if applicable).
These records should be made using standardized documents and may be incorporated into reports or audits. What distinguishes an ordinary watchman from an elevated professional is their level of presence. They don’t just write – they bear witness to the environment.
How can your internal state influence your focus and decision-making as a watchman during a critical event?
The watchman’s internal state directly affects their response capacity. An agitated mind may overlook subtle signals; an unbalanced emotional field can block intuition and slow reaction time. In critical situations, seconds matter.
When the watchman breathes consciously, maintains focus, and aligns their intent with collective safety, they enter a state of coherence. This enhances their ability to detect what the eyes miss — behavioral patterns, slight procedural deviations, or emotional shifts in the authorized worker. The body may be present, but it is the energetic field that truly sustains the role.
When the rescue plan fails, is it just an operational failure or a reflection of misalignment between team, environment, and intention?
When a rescue plan fails, the issue rarely lies solely on paper. It often stems from a lack of rehearsals, role clarity, or the team’s disconnection from the true purpose of the operation: to protect life. A signature on a PET without presence and accountability is just ink on paper. Where there is automatism, there are gaps.
A rescue plan can only hold if there is synergy among those who execute, supervise, and respond. It must be alive, rehearsed, revisited, and deeply understood. When everyone involved recognizes they are operating at the threshold between life and death, the plan transcends documentation, it becomes a vibrational pact, forged in technical skill, attention, and aligned intention.
If equipment were calibrated with the same level of care you give your PPE, would it save lives or put them at risk?
The care you give to your PPE reflects your level of awareness. A dirty helmet, a loose harness, or a neglected mask signal a negligent relationship with your body and, by extension, with life itself. This silent negligence echoes in the environment: if you mistreat what protects you, why would you treat the rest any better?
Measurement, ventilation, and gas detection equipment demand precision, yes, but more than that, they require energetic respect. Proper calibration begins in the mind of the operator. True safety doesn’t originate from regulations; it arises from coherence between what is preached and what is practiced, between what is worn and what is embodied. And it all begins with the smallest detail: how you care for your own PPE.
