Blog Series: Challenges of Maintenance Shutdown Management | Part 3/5

Maintenance shutdown safety is not just created by work permits, instructions or risk assessments. It is created by ensuring the right information is available to the right people at the right time.

A maintenance shutdown is one of the riskiest periods for a plant. Several contractors work simultaneously, work phases change rapidly and the working environment differs from normal production.

Furthermore, maintenance shutdowns are almost always associated with significant time pressure. Schedules are tight, there are expectations for the resumption of production, and delays can incur substantial costs. This urgency can lead to decisions being made with insufficient information or to work stages being rushed without adequate coordination.

Work permits, LOTOTO procedures (lockout, tagout, tryout) and risk assessments form the basis of safe working. However, continuous information flow and a shared situational awareness are also needed alongside them. When information does not flow, safety risks also increase – especially when work is done in a hurry.

The working environment includes several risks and safety factors.

The maintenance outage work environment is not only changing but also involves multiple simultaneous risks.

Working in the process industry often takes place in environments containing chemicals, hot liquids, vapours, and stored energy. In addition to these, work processes involve mechanical, electrical, and process safety-related risks.

During maintenance shutdowns, physical workplace risks such as working at height, fall hazards, and falling objects from upper levels are also highlighted. Simultaneous work stages can create situations where, for example, lifting operations, dismantling work, or welding directly impact the work of others.

For safety's sake, it is essential that all parties understand these risks and know how they affect their own work, especially when work being carried out around them can change the situation rapidly.

2. Work permits are only a starting point

A work permit defines the preconditions for performing a job and the associated safety requirements. It includes, for example, information on the necessary safety measures, such as energy isolation, pressure release, ventilation, or other site-specific confirmations.

A work permit indicates that work can commence safely once these conditions are met.

However, situations can change quickly during a maintenance shutdown. If changes are not communicated to all parties, the original work permit alone will not be sufficient to guarantee safe working.

In addition, safe working requires that employees have up-to-date work instructions available and that they are easily accessible. If instructions are scattered across different systems or are out of date, the risk of incorrect operation increases significantly.

3. Contractor collaboration requires shared knowledge

During maintenance shutdowns, several companies often work simultaneously, and the workforce can also comprise different nationalities.

Safe working requires different parties to be able to coordinate their work. This cannot be achieved without clear and uniform ways of sharing information.

When several different channels, tools, or operating methods are in use, information can become fragmented and inaccessible to some stakeholders. Additionally, potential language barriers can make it difficult to understand information and increase the risk of misunderstandings.

It is therefore important to agree on common communication practices and to ensure that information is readily available, understandable, and, where necessary, multilingual. When everyone works according to the same practices, cooperation flows better and safety risks are reduced.

4. Changes must be known immediately

During a maintenance shutdown, schedules change, new jobs are added, and the work order needs to be modified. At the same time, working conditions can also change rapidly – for example, area isolations, temperature, chemical exposures, or access routes may differ from what was previously agreed upon.

If information about these changes is delayed or not received by all parties, there is a risk that work will continue based on old information. This risk is particularly highlighted during times of urgency, when assumption-based actions increase.

From a safety perspective, it is not enough for changes to be communicated; it must also be ensured that the information genuinely reaches everyone affected by the change. This requires clear communication practices, effective channels, and accountability for ensuring the information is understood correctly.

Up-to-date and effective communication of information is as important as the safety instructions themselves.

5. A shared situational picture supports safe decisions

Safety is not a separate task or solely the responsibility of specific roles, but rather it is incumbent upon everyone involved in a maintenance shutdown. Every employee, supervisor, and contractor contributes through their actions to how safely the work progresses.

A common operating picture is only created if observations are actively shared. This means that deviations, risks, changes, and progress and readiness levels of tasks are communicated openly and without delay.

When the progress and completion status of the work are known to everyone, work phases can be coordinated more safely and incorrect assumptions about the state of the work are avoided. This is even more pronounced in a busy environment – without a shared situational awareness, decisions are easily made based on incomplete information.

When sharing information is genuinely valued, knowledge flows naturally and supports better decision-making and proactive safety management.

The shared situational awareness is therefore not just a management tool, but a shared responsibility of the entire work community and a key prerequisite for safe decisions.

Summary

Safety during maintenance shutdowns is built on many factors.

Work permits, LOTOTO procedures, and risk assessments are essential, but alongside them, smooth communication, up-to-date work instructions, and a shared situational awareness are necessary – especially when work is being carried out on a tight schedule.

Regardless of the systems, tools or communication channels used, there is no room for compromise in implementing security. Information must flow reliably, guidelines must be up-to-date, and operating procedures must be clear – without wavering.

When the right information reaches the right people at the right time, and safety is adhered to without exception, safety does not remain an isolated process but becomes a natural part of the daily management of a maintenance shutdown.
