PTI is committed to a people-first philosophy and strives to provide a safe, healthy, and friendly workplace. Guided by management commitment, we have established our “Environment, Safety and Health Policy” and related management systems. By aligning with international standards and applicable regulations, we continuously strengthen our safety culture to safeguard the health and safety of all employees and workers.

Occupational Health and Safety Management System

PTI has established a comprehensive Occupational Health and Safety (OHS) management system in accordance with ISO 45001, the Responsible Business Alliance (RBA) Code of Conduct, and applicable regulatory requirements. The Company has established dedicated management organizations, policies, and operating procedures, and continuously enhances management effectiveness through regular audits and management reviews.

The OHS management system covers all workers. Through hazard identification and risk assessment, safety training, workplace environmental monitoring, health management, and continual improvement, we minimize occupational safety risks, ensure a safe working environment, and work toward our goal of zero incidents.

The ISO 45001 Occupational Health and Safety Management System has been implemented across all PTI operating sites. To ensure its effectiveness and compliance with international standards, third-party certification bodies conduct annual surveillance and certification audits. (ISO 45001 Certificate)
