Safety has always been a top priority in high-risk industries.
Organizations invest heavily in procedures, training programs, hazard identification processes, and safety management systems to reduce risk and protect their workforce.
Yet despite these efforts, many Permit-to-Work (PTW) processes remain heavily dependent on paper forms, spreadsheets, emails, and manual coordination.
The permit itself is not the problem.
The challenge lies in how permits are managed, communicated, and tracked throughout the work lifecycle.
The Critical Role of Permit-to-Work Systems
Permit-to-Work systems exist to ensure potentially hazardous work activities are properly assessed, authorized, and controlled before work begins.
They are commonly used for:
Hot work
Confined space entry
Electrical isolation
Working at heights
Excavation activities
Simultaneous operations (SIMOPS)
The purpose is simple: ensure work is conducted safely and under controlled conditions.
However, as operations become more complex, managing permits manually becomes increasingly difficult.
The Visibility Challenge
One of the most common issues organizations face is a lack of real-time visibility.
Supervisors often need answers to questions such as:
Which permits are currently active?
Who approved the permit?
Have all required isolations been completed?
Are there conflicting activities occurring nearby?
Has the permit been extended or suspended?
When permit information exists across multiple locations, obtaining accurate answers can take valuable time.
In high-risk environments, delayed or incomplete information can increase operational risk.
The Hidden Risks of Paper-Based Processes
Paper permits may seem familiar and straightforward, but they often create operational challenges.
QRA is a quantitative risk assessment approach which shall provide information on the following:
Identification of hazards and potential hazardous events
Estimation of likelihood, causes, possible escalation and consequences of hazardous events and the adequacy of the mitigation measures
Identification of the dominating risk contributors and appropriate risk reduction, if applicable, which can potentially reduce the risk“>risk
Demonstration of risk to as low as reasonably practicable (ALARP) in accordance to risk acceptance criteria.
QRA also supports statutory compliance under the Control of Industrial Major Accident Hazards (CIMAH) 1996 Regulations by Malaysian Government Department of Occupational, Safety and Health (DOSH), and HSE Case for upstream facilities.
QRA study/review shall be carried out throughout the full lifecycle of project, facilities and operation:
Design Stage
Operations Stage
The QRA shall be reviewed as follows:
Onshore facilities – every three (3) years as part of CIMAH report review for Major Hazard Installation.
Offshore facilities – every five (5) years as part of HSE Case review.
Significant changes or modification to the project, facilities and operations that has the potential to introduce new hazards.
Among the common software used for the risk modelling and analysis:
Safeti
TNO Effects and Riskcurves
QRA is important to determine the risk of a facility whether it is acceptable or not hence it is important for the facility owner to conduct QRA to ensure the safety of the facility workers, surrounding people, and the environment.
Emergency response plan is a definite plan to deal with major emergencies.
Emergency response plan includes:
All possible emergencies, consequences, required actions, written procedures, and the resources available.
Detailed lists of emergency response personnel including their cell phone numbers, alternate contact details, and their duties and responsibilities.
Floor plans.
Large scale maps showing evacuation routes and service conduits (such as gas and water lines).
An emergency response plan specifies procedures for handling sudden or unexpected situations to:
Prevent fatalities and injuries.
Reduce damage to buildings, stock, and equipment.
Protect the environment and the community.
Accelerate the resumption of normal operations.
The emergency response plan includes the forming of an Emergency Response Team (ERT). Each of the ERT members will have specific roles and responsibilities during an emergency. ERT generally consists of:
Emergency Commander
Emergency Coordinator
First Line Crew / Rescue Squad
First Aider
Security Team
Floor Warden
Completing a comprehensive plan for handling emergencies is a major step toward preventing disasters. Exercises and drills may be conducted to practice all or critical portions (such as evacuation) of the plan. The plan should be revised when shortcomings have become known and should be reviewed at least annually.
Incident investigation is a formal process for investigating incidents, reporting and tracking. This process also includes the resolution and recommendations generated by the investigations. The results/findings of the investigation process should be documented in a standard incident report form.
Incident investigation is a way of learning from incidents that occur over the life of a facility and communicating the lessons learned to the workers. By identifying and addressing the root causes of equipment failures and personnel errors, leveraged solutions can be developed that will reduce the frequency of incidents and/or reduce the consequences of the incidents. Output of the incident investigation should be used to improve the safetyperformance of the plant.
Incident investigations are conducted whenever and wherever incidents occur. The investigation team will collect information at the incident scene and conduct interviews with victim and witness. Reporting to the management is important as they are the policy makers. Investigation procedure is documented as guidelines for investigator(s) to perform investigation.
The incident investigation team would perform the following general steps:
Scene management and assessment (secure the scene, make sure it is safe for investigators to do their job).
Witness management (interview victim and witnesses).
Personnel who have formal training in incident investigation or root cause analysis typically perform investigations and lead investigation teams. A multidisciplinary team is appropriate for incident investigations with greater consequences and risks. At some facilities, the incident investigation is used to assign blame to personnel involved in an incident. A more effective approach is to develop recommendations that address the systemic causes of the incidents.
Permits to work will often be found in high-risk industries, but what is their purpose?
A permit to work system is a formal documented system, used to control high-risk activities. They are usually issued by a manager or supervisor and allow a person or group of people to carry out a task, under strict controls.
Permits will authorize certain personnel to carry out high-risk work at a specific time, providing that the procedures detailed in the permit are followed. Permits to work are likely to be required for activities such as electrical works, hot works, excavations, work at height and confined space works.
So how do permits to work ensure safety?
A manager or supervisor will give written permission to carry out a task
Return the area to a safe state on completion of the work
Give a means of communication and written record
Types of Work Permit:
Hot Work Permit – Authorization to perform tasks in conditions that produce sparks, flames, or any other source of ignition.
Excavation Permit – Authorization for personnel to mine or dig land to build infrastructure, extract resources, etc.
Work-at-Height Permit – Authorization to work on elevated spaces e.g. ladders, scaffolds, Mobile Elevated Work Platforms (MEWP), and other spaces that are elevated.
Confined Spaces Work Permit – Authorization to perform tasks in a narrow space that is prone to hazards like asphyxiation, fire, toxic atmosphere, etc.
In order for the permit to work and fulfill its purpose, it needs to cover all the legal requirements and strict adherence to the procedures by all workers.
