Quality, Safety, Health, and Environment

          In addition to supply of electricity, EGAT consistently ensures that our operations are managed sustainably, effectively, and efficiently. In order to achieve this, EGAT commits to regulations and laws of Quality, Safety, Health and Environment.

Promotion of Occupational Health and Safety performance

          EGAT promotes occupational health, safety and work environment that are in line with its policy of “developing participatory business on a continuing basis with an emphasis on proactive prevention of accidents with respect to all applicable laws and international standards.” This policy was implemented under a fundamental hypothesis that “if an organization has in place an effective and efficient occupational health, safety and environment management system, existing work risks will be controled at acceptable level. Such system will reduce the chances of accident and prevent illness from contact with hazardous environment”. The following guidelines were established for EGAT’s occupational health, safety and environment management.

  1. Implemented a management system that was in line with the Ministry of Labor’s Regulations on the Prescribing of Standard for Administration and Management of Occupational Health, Safety and Environment, B.E. 2549 (2006). EGAT had 41 operation areas across the country and registered them as operative units with the Department of Labor Welfare and Protection. Each operative unit set up a bi-party occupational health, safety and environment committee consisting of appointed and elected members at the ratio stipulated by the Ministry of Labor’s regulations. Based on the current number of 21,377 eligible employees with voting rights, there were 238 elected committee members.
  2. Operative units in each operation area set up an occupational health, safety and environment management system whose effectiveness and efficiency were measured by their achievement of international standard certifications, such as Thai Industrial Standard for Occupational Health and Safety Management System (TIS 18000) and the OHSAS 18000 (Occupational Health and Safety Assessment Series).
  3. Set up work safety units and safety personnel in EGAT’s administrative structure.

        3.1     Set up work safety units and safety personnel in all operation areas.
       
3.2     Set up a Work Quality and Safety Promotion division to make recommendation
                   to the management on  various safety management issues and to provide services
                   in the following areas:

    • Give advice on the development of occupational health, safety and environment management system.
    • Implement safety engineering operations.
    • Develop safety training programs required by laws.
    • Inspect, evaluate and measure elements of work environment such as heat, lighting, noise, dust, chemical substances, bacteria, etc.
    • Inspection and evaluation of occupational safety, health and environment management system by a person(s) who are not related to the inspected operative unit.
       

National level awards in 2011

          In 2011, EGAT won awards for outstanding operative facilities in occupational health, safety and environment from the 25th National Work Safety Week organized by the Department of Labor Welfare and Protection, the Ministry of Labor in which 28 locations of EGAT’s operative units participated.   Vajiralongkorn dam and Nam Phong power plant have won this award for 11 consecutive years.  

Work-related Accidents and Injuries Statistics

           During 2011, there were 149 cases of work-related injuries and illness or personnel accidents, 17 cases of which were disabling or severe injuries, 101 cases were non-disabling or minor injuries, 2 deaths and 29 cases were pending for conclusion. EGAT’s rate of work-related injuries or illness cases in 2011 decreased by 14.37% from 174 cases reported in the previous year. The rates of disabling or major injuries decreased by 61.36% while the rates of non-disabling or minor injuries decreased by 20.47%. However, there were fatalities this year. (In 2010, there were 44 disabling or severe injuries, 127 non-disabling or minor injuries and no fatalities).    

          EGAT’s disabling injury frequency rate (IFR) was 0.47, a decline of 0.31 (from 0.78 in 2010). The incident rate (IR) of non-fatal work-related injuries and illness was 0.08 for 200,000 employee-hours worked. This figure was lower than the disabling injury frequency standard index which is 3.2 for 200,000 employee-hours worked according to the NAICS Code for electric power generation, transmission and distribution (Injuries Facts 2010 Edition, the National Safety Council 2008).

          In 2011, EGAT’s disabling injury severity rate (IRS) was 303.81, which had risen from 2011 by 109.54 (the 2010’s IRS rate was 194.27).

     •    Emissions of SO2, NOX and Particulates

          EGAT continues to enforce strict measures to adopt sound environmental technologies for the control of emissions of sulfur dioxides (SO2), nitrogen oxides (NOX) and particulates. New technologies and practices included the installation of the low NOX burner to reduce nitrogen oxides emission, the electrostatic precipitator (ESP) to control particulates, and flue gas desulfurization (FGD) to lower the level of sulfur dioxides. Air quality has been continuously monitored. The continuous emission monitoring systems (CEMS) has been installed to collect data and sent by EGAT’s communication system to the Department of Industrial Works, the Pollution Control Department, and relevant agencies.  

          In 2011, emissions of SO2, NOX and particulates from EGAT’s power plants were within the standard as stipulated by the Ministry of Industry’s notification regarding emissions from power plants B.E. 2547 (2004). In 2011, aggregate volumes of emissions from EGAT’s power plants were 24,943, 80,303 and 1,611 tons respectively.

     Noise Prevention and Control

            EGAT continues using measures for the control of noise level caused by the operations of power plants. Silencers were installed on machineries and equipment that may produce harmful noises. Monitoring of noise levels was also carried out both within the power plant areas and in the nearby communities. The results of noise level monitoring within all of power plant areas and community areas were in compliance with the standards determined by the National Environment Board (NEB) and the Ministry of Industry.

     Water Quality Management

            To monitor possible water pollution that may have impacts on the environment and the nearby communities, EGAT has implemented measures for water quality management and control according to power plant types. For hydropower plants, the emphasis is on the management of office and residential water use, requiring that waste water quality must meet the determined standard. Implementation of water saving campaigns is also endorsed. For thermal power plants, EGAT emphasizes the adoption of water saving measures and the reuse of discharged water. Wastewater from all power plants must be treated before being released and the quality of water must meet the standards required by laws.

     Environmental Management

            During the power project development, EGAT continues to put priority on the management of social and environmental aspects in pursuit of sustainable development. EGAT has also put emphasis on the adoption of management approaches which are in compliance with relevant regulations and environmental laws. These approaches include the environmental impact prevention and mitigation measures and the monitoring activities covering all environmental aspects ranging from the physical and biological resources, human use values, to the values to the quality of life. Mitigation measures in focus were the conduct of the social impact assessment (SIA) and the health impact assessment (HIA) as well as the applying of the ISO 14001 environmental management system (EMS) and the occupational health and safety management system standard (TIS 18001) to the power plant operations during all stages of development. Management approaches carried out in parallel were the participation and involvement of all groups of stakeholder in order to create better understanding and seek acceptance for the project development.
