ST is committed to ensuring the safety of its employees and all people working on behalf of ST through the mitigation of risk and provision of safe working conditions. For over ten years, ST has been firmly focused on achieving zero accidents in the workplace and providing a high degree of protection to safeguard employees, physical assets and neighboring communities.

ST began certifying sites to the OHSAS 18001 safety management standard in 2001. By 2003 all of our manufacturing sites were certified. Eleven of our non-manufacturing sites have also been certified to OHSAS 18001. ST has a dedicated ‘loss prevention’ program to ensure manufacturing and large non-manufacturing sites have an appropriate level of protection against fire and associated hazards (e.g. smoke, corrosion, explosion, etc.).

Since 2005, ST has publicly committed to annual safety targets in its Environmental, Health and Safety Decalogue (see more on our Environment page).

Damien Tisserand, Corporate Safety, Loss Prevention & Chemicals Senior Manager

“Safety is an integral part of our company culture. Our sites are continuously innovating to make safety a way of life for everyone, including external contractors working at our sites. While increasingly strengthening our safety management robustness, we are also working on employees empowerment through regular training, communication and awareness.”

Safety management and programs

ST manages its Health and Safety (H&S) systems and performance to the international OHSAS 18001 standard, which is widely recognized as the most rigorous for Occupational Health and Safety (see more on our People page).

ST takes a proactive approach to safety, one which looks forward, anticipates and predicts risks in order to prevent injury. Our strategy involves identifying a hazard, assessing the risks, proposing recommendations and corrective actions and improving systems. Reporting and management of near-misses is also a key aspect of this approach.

Our Health and Safety strategy is supported by:

  • Comprehensive safety rules, supported by corporate procedures, guidelines and training on subjects such as Occupational Health and Safety, major risk identification and assessment, chemical risk management and crisis response.
  • A safety management system self-assessment tool to measure, improve and illustrate sites’ safety performance, evaluating 15 elements that are essential to robust safety management systems. These include leadership, risk control and monitoring, compliance and emergency preparedness.
  • Quarterly monitoring of safety performance across all of our sites (including small non-manufacturing sites) to track several indicators such as:


  • Recordable cases of work-related injuries and illnesses (the number of recordable cases per 100 employees);
  • Severity of work-related injuries and illnesses (the number of calendar days lost due to injury/illness per 100 employees);
  • Breakdown of 'industrial' cases (e.g. involving chemicals, mechanical apparatus etc.) and on-site 'domestic' recordable cases (e.g. fall, slip, struck by or against a door, chair, structure, etc.);
  • Average safety training hours per employee;
  • Estimated cost to ST of work-related injuries and illnesses;
  • Lost work day case rate for ST subcontractors (at all ST manufacturing sites and seven main non-manufacturing sites).


  • Regular safety visits and internal audits of manufacturing and major non-manufacturing sites (at least every two years).
  • Health and safety visits by external experts, who evaluate safety management at manufacturing sites, including testing the effectiveness of protective equipment against fire-related hazards. By 2012 four manufacturing sites received a high performance rating (HPR) and six an adequate performance rating (APR).
  • Third party OHSAS 18001 audits at 23 certified sites.
  • Regular safety training and awareness, using a matrix that matches basic and specific training requirements associated with different ST activities, based on risk exposure.

Locally, each manufacturing and large non-manufacturing site has a dedicated safety team. All of our smaller sites also have one person responsible for safety aspects and associated reporting.

Safety objectives

Our Sustainability strategy and EHS Decalogue commits us to:

  • Number of work-related injuries and illnesses: remain among the best-in-class companies and with a medium term target Recordable Cases Rate* at 0.2 or less;
  • Severity of work-related injuries and illnesses: remain among the best-in-class companies and with a medium term target Severity Rate* at 2 or less;
  • Improve the main on-site subcontractors Lost Work Days Cases Rate* until 0.2 and then remain at 0.2 or less;
  • Ensure high ergonomics standards for our working environment;
  • Ensure ST employees have an average of four hours of training and awareness per year on Environment, Health and Safety (EHS) topics.

Our latest results against these objectives are available in our Sustainability report.
