Introduction

The pre-commissioning and commissioning stages are critical to the construction workplace. All teams involved should pay close attention, vigilantly check for commissioning safety hazards, and take appropriate action to address them.

The most common testing and commissioning hazards include electrical shock, chemical exposure, confined-space risks, falls from height, mechanical entrapment, fire and explosion hazards, and ergonomic injuries from equipment handling.

The landscape of construction commissioning safety risks is rapidly evolving due to digital transformation, complex project ecosystems, and increasingly stringent regulatory requirements.

When we see the buildings beside us, we look at the architecture and always form an opinion. Some are man-made marvels, some are mediocre, while some are technically correct. But one thing common to construction work, including buildings, roads, bridges, and all possible sites in the sector, is that it involves tedious, arduous work.

The construction industry must plan rigorously before taking on any project. Of course, as the work progresses, many changes take place, but the initial planning is of the utmost importance.

If you are reading this blog, you are likely related to the construction industry and know how vital the pre-commissioning and commissioning stages are. Additionally, testing and commissioning hazards in the pre-commissioning and commissioning phases need extra attention.

We all know about the pre-commissioning safety hazards of the construction industry. But let us look closely at the hazards involved during these stages and whether commissioning safety hazards requires updating the existing safety measures.

Recent industry insights indicate that construction safety in 2025 is increasingly driven by technology adoption and data-based risk monitoring. Also, pre-commissioning hazards are no longer just physical—they are increasingly systemic and digital.

What Happens During the Commissioning and Pre-commissioning Procedure?

The Purpose of Commissioning and Pre-commissioning Procedure

  • Verify that the plant or system is installed correctly.
  • Detect and correct faults before energising or introducing process materials.
  • Ensure compliance with design specifications, safety standards, and regulatory requirements.

During the pre-commissioning procedure, teams must test all machines and equipment to ensure they function correctly. They should be appropriately & comprehensively checked for damage, and all the features must work properly to start operations smoothly. The competent staff reviews the entire setup to ensure everything from documentation to equipment is in safe and proper condition.

Similarly, in the commissioning stage, the team checks whether all the tasks, documentation, and equipment are ready for the start of the process. These testing and commissioning safety precautions ensure that the site is prepared and safe for the actual work to begin.

In industries such as oil and gas, pre-commissioning activities often involve flushing, cleaning, and loop checks. This ensures integrity before startup. These testing and commissioning safety precautions are crucial for avoiding delays or failures due to overlooked details.

Possible Hazards During the Commissioning and Pre-Commissioning Stages

Safety is everyone’s responsibility when managing workplace tasks. The same applies to the pre-commissioning activities and commissioning stages in the construction sector.

For example, even if the equipment has been double-checked, the user must ensure it is safe to work on/with, read the manual, and personally inspect its functioning. Remember, human and machine errors are always possible and can be avoided if the worker is vigilant, alert, and responsible.

Hazards on a construction site are unique; therefore, these potential hazards require hawk-eye to ensure minimal or no incidents. Beyond traditional hazards, modern construction site commissioning hazards now include incorrect algorithm-based decisions, failure in automated shutdown systems, over-reliance on predictive safety systems, and more.

Let us discuss team-wise roles, responsibilities, and solutions for pre-commissioning safety.

Construction Team

The construction team is responsible for managing the safety aspects of heavy civil equipment, moving pieces of large equipment, and all the related construction safety aspects.

An incident is likely to occur if the construction team does not set the correct barriers and boundaries at the worksites. They need to keep an eye out that the place is accessed only by the required & trained professionals. Additionally, the construction team should stay within their workplace boundary and complete the work dedicated to them.

Health, Environment and Safety Team (HSE)

The HSE team has to work closely with the commissioning team of all the departments to know their work properly. From equipment work to technical details of the project, the HSE team needs to know the details to ensure the project execution and commissioning safety hazards plan is compliant in all forms.

Suppose the HSE team is not properly checking the technical details and equipment used; there is a chance of possible hazards. Because if anything is not compliant with the environment or green belt safety measures, the project can be stayed by authorities, creating innumerable problems.

In sectors like oil and gas, pre-commissioning activities are closely linked to safety checklists and testing and commissioning safety precautions. These checklists and precautions must be shared with the HSE team for better integration.

Operating Team

These include the PTW and LOTO teams. The operating team ensures that the machinery works as per the defined rules described in the commissioning and pre-commissioning period.

The permit to work (PTW) authorities must ensure that operational, maintenance, scheduled, and unscheduled works are in sync with the plans.

The Lockout-Tagout Software (LOTO) team should know how to manage resources, eliminate human error & increase information availability.

This team is responsible for switching off and on all the equipment and giving permissions to the equipment operator. Thus, the company may have to bear a huge loss if the equipment breaks or the equipment operator gets injured. And trust us, it is more dangerous than it actually sounds.

Emergency Response Team

The name itself has an emergency, so apart from being vigilant, this team must ensure they are the “Mr know it all.” They should be able to take over the emergency situation, quickly resolve the issues and deal with any incident. This team should have effective Emergency Preparedness & Response Planning, ensuring that employers and workers have the necessary equipment, know where to go, and know how to keep themselves safe during an emergency.

These protocols tie into testing and commissioning safety precautions. They also guide how emergencies must be handled during pre commissioning activities in oil and gas.

Expert Consulting

It is always better to hire the best consultants regarding workplace safety. Therefore, having an EHS team of consultants who can guide you and be with you at every step of the work stages will be a blessing in disguise. These consultants know critically every piece of information required to be compliant and safe. Additionally, they have a set of tools and digital devices to make the work easier.

For example, if you have a safety consultant, they can intricately tell you about the dos and don’ts in the pre-commissioning and commissioning phases of construction. Also, if you have a digital tool to ensure that the checklist is actually checked, approved, and in place, you know you have less to worry about.
