IRPC promotes safety in every aspect, including personal safety, process safety and transportation safety. This effort is achieved by the use of high safety standard to reach the goal of being a safety workplace with zero-accident and strong safety culture among its employees and suppliers. With its utmost commitment to build safety culture into every work process, the target of zero accident and zero emergency case is set for all workforce and contractor to build the personal safety awareness. Furthermore, IRPC established a formal process for employees to “stop work if unsafe” in the procedure manual. The process outlines the procedure for employees to notify and stop work in situations where there is prominent danger, or if it is assessed that continuing work could cause greater harm and danger.

2Management System/Process

Personal Safety at IRPC focuses on regular work performance by employees with due regard for safety, with Zero Accident as the ultimate corporate goal along with Zero Emergency Case and a promotion of constant awareness, recognition, and promotion of safety and work as a corporate culture. To this end, various projects, led by Quality, Safety, Occupational Health, Environmental & IRPC Industrial Zone, including the Goal Zero Accident Project, reminded workers to pay primary attention to work safety. The Safety Excellence Project nurtured safety awareness, promoted safety leadership, and trained workers to help and warn one another. The Safety Network and Sharing Project established a safety network among PTT Group. The Integrated Database Management System Project analyzes all plant incidents for grouping in to databases, looks for their root causes, and develops preventive or remedial guidelines to prevent recurrence. In addition, IRPC applies PSM (Process Safety Management) and conducts the annual plant safety risk assessment against TIS/OHSAS 18001 for safety throughout production processes, which enables IRPC to maintain its decent safety statistics. The internal auditor team was appointed and trained to ensure the competency of those people to conduct the PSM audit program. The audit results will be analyzed to develop the corrective and preventive actions development for continuous improvement.

IRPC recognizes the importance of the occupational health and safety management in compliance with laws and regulations. IRPC has appointed the Safety Occupational Health Committee (SHE), which comprises of equal numbers of representatives from both employer and employee with a vocational safety officer as secretary. The committee is responsible for deliberating policy and safety management plan, taking part in assessing and identifying risk, supporting safety promotional activities, as well as monitoring performance and presenting mitigation measures through monthly meeting. Other committees are also appointed, include, IRPC Management Safety & Occupational Health Committee (MANSAFCOM), Department Safety Committee (DEP.SC) in order to manage occupational health and safety issues as efficiently as possible

Process Safety Management

IRPC has the Operational Excellence Management System (OEMS) and the Process Safety Management (PSM) in place and has a risk assessment on safety issue for each plant every year according to TIS/OHSAS 18001 and every five year by law or whenever there are changes in process. In addition, IRPC also worked with PTT Group to develop PSM guidelines that comply with international standard. IRPC continuously conducts operations in line with the safety management policy. In 2016, Safety Critical Equipment criteria was introduced to prioritize the urgency of maintenance orders, especially for safety related machines and equipment, for example, human exposure protection equipment or emergency pressure release equipment, etc.

SHE Excellence

IRPC conducts the Safety Excellence Assessment to review and improve the process in order to prevent and reduce potential risks, promote occupational health and safety, and establish a corporate safety culture. In 2020, IRPC outlined a new criteria for the SHE Excellence Award which consist of 5 different levels ranking from Bronze, Silver, Gold, Platinum, and Diamond.

Safety Culture

IRPC promotes its safety culture by devising policies and implementing various activities like Behavior Safety Management (BSM) which encourage employees to report the unsafe conditions and unsafe behavior including recommendations on safety practices. In addition, IRPC’s procedure manual outlines the process to “stop work if unsafe”, which employees can stop work in dangerous situations or is at risk of danger. The process also allows employees to remove themselves from unsafe working conditions and environment without being penalized. Safety training is provided for all employees, contractors, and workers, and guidelines are given to supervisors, who must treat contractors like IRPC employees. Finally, an inspection team was appointed to strictly audit conformance to safety rules. Once incidents happen, IRPC will appoint an investigation panel to identify causes, turn them into knowledge, and transfer such knowledge to employees to prevent recurrences. Safety journals and behavior records are regularly prepared and publicized

IRPC recognizes the importance of a safety culture by conducting a safety culture assessment which surveys more than 80% participants using interviews, questionnaires, observations, and review of documentations with a final goal of achieving a proactive safety culture measured based on SHE Culture Score with a scale of 5 levels. Specifically, IRPC outlines a long-term target of achieving a generative behavior organization with a SHE Culture Score of 4.20 in 2025.

Health Management

In addition to its commitment on the safety issues, IRPC also foresees the importance of healthy lifestyles promoting among employees. For this reason, IRPC has started “Good Health Starts Here” Project to help IRPC’s employees in different health issues, such as employees whose Body Mass Index (BMI) higher than the standard, by providing free health lunches such as organic vegetables and chilli pastes, providing health snack in the meetings such as fruit, herbal juice, etc. As well as providing facilities and exercise equipment for employees.

In 2020, IRPC developed a Health Performance Indicator Score (HPI), established by the Safety, Occupational Health and Environmental Management department at IRPC. The Health Performance Indicator Score (HPI) assesses the health of IRPC employees based on performance of various executed strategies. Such strategies are used to improve the health of IRPC employees through different health monitoring, training, and promotion programs including industrial hygiene and control of workplace exposures, first aids training, fitness for work assessment, and health surveillance.
