Safety Course in Work at Height NR 35

Height safety using fall arrest systems and visual anchorage inspection.

Technical Name: TRAINING COURSE NR 35 – SAFETY IN WORK AT HEIGHT – WORKER LEVEL

Reference: 10044

We offer courses and training in technical language: Portuguese, English (Regional), Croatian, Japanese, Spanish, French, Chinese (Regional), German, India (Regional), Arabic, Korean, Russian, among others.

What Is the Purpose of the NR 35 Training Course?

The NR 35 – Work at Height Safety Training Course primarily aims to qualify workers to safely and responsibly perform any activity carried out above two meters from the lower level, whenever there is a risk of falling. Therefore, the training goes beyond simply conveying regulatory content: it seeks to develop technical competence, risk perception, and preventive conduct based on real field situations.

Initially, the course introduces the requirements of NR 35. As it progresses, however, it guides participants through the practical internalization of fundamental procedures, such as:

Selecting, adjusting, and correctly using Personal Protective Equipment (PPE);
Interpreting and executing Preliminary Risk Analysis (PRA);
Applying collective and individual control measures;
Responding safely in emergency scenarios, including basic rescue techniques.

Furthermore, the course fully complies with subitems 35.3.1 to 35.3.8 of NR 35, ensuring that, by the end of the process, the worker is not only aware of what must be done but is also formally trained, evaluated, and certified according to the legal and occupational safety standards.

Work at Height Safety Course: What Are the Most Common Mistakes in PPE Selection and How to Avoid Them?

Selecting the correct PPE for work at height goes far beyond choosing what “seems appropriate.” It requires technical analysis, compliance with standards, and a realistic understanding of the operational context.
Even in environments where formal training is provided, some errors persist, often due to habit, haste, or overconfidence.

Here’s a table summarizing the most frequent mistakes, their direct consequences, and the technical corrections based on applicable standards:

Common Mistake	Consequence	Technical Correction (Based on Standards)
Generic PPE selection	Incompatibility with the actual risk type	Assess technical specifications based on ABNT NBR 16489
Failure to check the CA (approval)	Legally invalid PPE	Verify validity on the Brazilian Ministry of Labor website; document delivery
Improper adjustment of PPE	Risk of fall due to slippage or detachment	Provide hands-on training for correct fitting
Not considering the complete system	Incompatibility with connectors/anchorage	Design the PPE as an integrated protection system
Worn or expired PPE	Loss of resistance; risk of equipment failure	Implement a pre-use and periodic inspection routine, with records

In summary, PPE selection demands technical knowledge, ongoing inspection, and a genuine commitment to safety. No equipment protects on its own — its effectiveness depends on conscious and system-oriented use.

Why Is Perceptive Behavior Critical When Working at Height?

Perceptive behavior refers to the worker’s active ability to identify, anticipate, and respond to risk signals in real time, even before they manifest as operational failures or accidents.

With consistent training and field exposure, the worker sharpens their perception and begins to detect subtle environmental changes, such as abnormal displacements, unusual sounds, sudden weather shifts, or unsafe behavior from others. This type of conscious, intentional attention acts as an extension of the protection systems, boosting vigilance and reducing reaction time.

Therefore, developing perceptive behavior is not optional it is a strategic risk control mechanism under NR 01 (GRO/PGR) and NR 35.

Why Is Routine Exposure One of the Greatest Hidden Threats in Work at Height?

Operational familiarity creates an illusion of safety. When a worker performs the same task repeatedly without incident, the brain gradually lowers its guard. This process, known as risk habituation, causes workers especially the experienced ones, to overlook critical steps and warning signs.

Consequently, periodic training and behavioral reinforcement become essential, as required by NR 35.3.3, to interrupt this cycle and restore the worker’s state of alertness.

What Criteria Should Guide the Choice Between Fall Arrest, Work Positioning, or Restraint Systems?

According to NR 35, ABNT NBR 16489, and ABNT NBR 16325, the proper system must be selected based on task type, risk level, structure, and fall clearance. See the table below:

System	When to Use	Purpose
Restraint	When physical means can prevent access to the fall hazard zone	To prevent exposure to the fall risk area
Positioning	When stability is required to work with both hands	To allow stable access and postural control
Fall Arrest	When a fall cannot be prevented entirely	To contain and minimize injury upon a fall

Thus, the system must be selected based on a Preliminary Risk Analysis (PRA) and consider available fall clearance, structure type, and shock absorption needs. The goal is smart prevention, not mere regulatory compliance.

What Is the Relationship Between Task Time Management and Safety in Work at Height?

Effective time management balances productivity with prevention. When workers are pressured to meet deadlines without sufficient time for planning, installation of protections, or risk analysis, the likelihood of critical errors increases significantly.

According to NR 01 (PGR) and NR 35, time allocation must include:
Risk analysis and PRA
PPE inspection
Installation of collective protection systems
Team communication and monitoring

Well-structured time planning ensures that safety becomes part of the operational flow, not a delay.

Why Doesn’t the Mere Presence of PPE Guarantee Safety?

Because safety lies in the correct and consistent use of the equipment, not just its presence. A harness, for instance, only protects if it’s properly adjusted, securely connected to a certified anchorage point, and free from defects.

Both NR 06 and NR 35 require not just the delivery of PPE but also practical training, usage documentation, and periodic evaluations. In this sense, safety is an ongoing action — not a decorative formality.

How Can Communication Failure Be a Primary Cause of Accidents at Height?

In high-risk environments like work at height, communication is not a minor factor, it is the invisible infrastructure of safety. A misunderstood command, a missing signal, or a silent radio can turn a controlled activity into a high-risk situation.
Unlike other workplaces, where errors can often be corrected in real time, in height work reaction time is the boundary between prevention and accident.

The most common failures include:
Unvalidated verbal commands
Absence of visual protocols in noisy areas
Mismatch between operators and spotters
Lack of pre-task radio checks
Improvised or missing signage

Thus, both NR 01 (subitem 1.5.3.3) and ISO 45001 (item 7.4) emphasize the need for formal, clear communication protocols, especially in interdependent tasks with fall risk.

You’ve Mastered the Task… So Reviewing the PRA Daily Might Seem Redundant — Or Is It?

At first glance, reviewing the Preliminary Risk Analysis (PRA) daily may seem repetitive, especially for experienced workers. Familiarity with the task often creates a false sense of stability, as if the conditions remain unchanged.
However, this perception overlooks a critical truth: risk evolves with each new variable introduced into the environment.

For example:

Today’s wind is not the same as yesterday’s;
The colleague nearby may be fatigued;
The scaffolding that was secure yesterday may now be compromised;
The anchorage point may have been altered.

In reality, reviewing the PRA daily is not bureaucracy it’s operational intelligence. It reflects the understanding that experience doesn’t neutralize risk; it enhances the responsibility to recognize it earlier.

What is the importance of conducting the nr 35 – safety in work at height training course in the worker’s native language?

Delivering the NR 35 – Safety in Work at Height Training Course in the worker’s native language is essential to ensure the effectiveness of the training, operational safety, and legal compliance. When the content is fully understood, the worker performs procedures correctly, identifies risks, and adopts preventive measures assertively.

Furthermore, the legislation requires actual training, which implies full understanding of the information provided. Courses delivered in languages not mastered by the worker compromise the validity of the training and significantly increase the risk of accidents, with possible legal consequences for the company.
Using the native language also improves performance in evaluations, facilitates learning of technical terms, and strengthens the safety culture and team engagement.

Roof work is high risk and falls from roofs, through fragile roofs and fragile roof lights are one of the most common causes of workplace death and serious injury.
As well as in construction, these accidents can also occur on roofs of factories, warehouses and farm buildings when roof repair work or cleaning is being carried out.
You must:
Take account of weather conditions that could compromise worker safety;
Check that the place (eg a roof) where work at height is to be undertaken is safe.
Each place where people will work at height needs to be checked every time, before use;
Stop materials or objects from falling or, if it is not reasonably practicable to prevent objects falling, take suitable and sufficient measures to make sure no one can be injured, use exclusion zones to keep people away or mesh on scaffold to stop materials such as bricks falling off;
Think about foreseeable situations and make sure employees know the emergency procedures.
Don’t just rely entirely on the emergency services for rescue in your plan.
