Improvisation in work at height is often the cause of most accidents. Whether on industrial roofs, facades, steel structures, or lifelines installed for maintenance.
A procedure helps organize each task safely, reduce incidents, and ensure that all operators know the necessary preventive measures. In addition to complying with regulations, a good procedure improves efficiency, coordination, and control during the work.
What Is a Work at Height Procedure?
A work at height procedure is a technical document that defines how a task involving a risk of falling is planned and carried out. It is not just about filling out paperwork or handing out PPE to staff. The real goal is to ensure that every operator knows:
- What task they must perform
- How to carry it out safely
- What measures they can take to prevent accidents
- What risks exist
Although many companies have generic procedures, the reality is that every job is different. Stepping onto a fragile roof is not the same as working on an aerial work platform or performing maintenance in an industrial building, which is why each task must have the procedure suited to the conditions of the job.
Phases of the Procedure for Work at Height
A procedure must follow several structured phases to ensure safety while the work is being carried out.
Prior risk assessment
The first phase must always be the risk assessment. Before going up on a roof or installing any fall arrest system, the work environment must be analyzed. This is where the main hazards are identified, such as:
- Slippery surfaces
- Fragile roofs or panels
- Presence of electrical cables
- Unsafe access
- Weather conditions
Wind, rain, or even extreme temperatures can turn a simple task into a risky situation. In work at height, environmental conditions matter far more than we think.
Selection of protective equipment and systems
Once the risks have been located, it is time to define which preventive measures we will adopt. The priority must always be collective protection, through systems such as:
- Safety guardrails
- Fall arrest nets
- Safety nets
- Platforms
When the risk cannot be completely eliminated, personal protective equipment (PPE) comes into play. It is important to point out something that happens very often here: having a harness does not mean working safely. The equipment must be certified, inspected, and in good condition. In addition, the worker must know how to use it. It seems simple, but it is still common to find poorly adjusted harnesses or bad connections.
Execution and supervision of the work
While the work is being carried out, there must be continuous supervision to verify that all the preventive measures specified in the procedure are being followed.
The person in charge must verify:
- Correct use of fall arrest systems
- The condition of the anchors
- Favorable conditions throughout the entire activity
- Compliance with protocols
It is also advisable to hold a short briefing before the work. This meeting is essential for reviewing tasks, clarifying doubts, and confirming that all operators know the procedure. Routines like this reduce errors and noticeably improve team coordination.
Access planning
Another fundamental point within the procedure is access planning. Many incidents do not occur during the main work, but when climbing up to or down from the work area:
- Poorly placed ladders
- Unstable footholds
- Improvised access
For this reason, the procedure must clearly state how to reach the area, which systems to use, and what limitations exist. The clearer the document, the less room for error.
Example of a Work at Height Procedure
A common example is maintenance of industrial roofs. Before starting the work, we will check the condition of the roof and, if fragile areas are identified, temporary lifelines or collective protection systems will be installed.
Next, the area below will be cordoned off to prevent the risk of falling tools or objects.
Throughout the entire job, operators use fall arrest harnesses connected to certified points, and the supervisor constantly checks the working conditions. If strong gusts of wind or rain appear, work will stop immediately.
This kind of organization not only improves safety, but also makes it possible to work more efficiently and professionally.
Today, companies that work at height are no longer set apart by having good equipment. What really makes the difference is advance planning, technical experience, and the ability to apply procedures adapted to each situation.
Mandatory Safety Protocols
Another essential aspect is the rescue plan. Many companies focus on preventing falls but forget how they should act if an accident does occur.
In work at height, reaction time is critical: an operator suspended after a fall can suffer serious consequences within a few minutes due to harness suspension syndrome. For this reason, any work procedure must include a rescue plan.
Personnel must be trained and have the means to act immediately.
Mistakes That Invalidate a Work at Height Procedure
There are common mistakes that can invalidate the procedure or increase risks during the work:
- Using uncertified, unverified anchor points
- Failing to account for weather conditions
- Failing to define the safety measures properly
- An incomplete, poorly written procedure, which can confuse workers.
Conclusion
The work procedure should not be seen as something mandatory, but as a tool for preventing accidents, ensuring safety while the work is carried out.
A well-drafted procedure not only complies with regulations, but also helps minimize risks and improves the organization of work at height.
