Additionally: We are not accredited, however our management system is based on a best practice framework and legislation allowing us to identify and assess risk 403-2 Hazard identification, risk assessment, and incident investigation Refer to the “Supporting our employees” section of the 2021 SR. Additionally: We encourage a culture where all employees seek to acknowledge, report and remediate all hazards and unsafe behaviours that could potentially bring harm to ourselves or our colleagues. We also encourage a culture where all employees positively embrace and share safe behaviours. As set out in the employee roles and responsibilities guidance, all employees have a specific responsibility for, 1) Challenging unsafe acts and conditions and engaging with those involved to agree the necessary improvements required and 2) Taking ownership of identified hazards and taking immediate corrective action where it is safe to do so. To enable us to track, monitor and identify areas for improvements we report hazards, safe and unsafe behaviours using the Company reporting system, SafetyNet. Data is analysed routinely by the HSW Performance and Reporting team and as part of the performance measurement and monitoring process. Any identified changes are made within the relevant standards and risk assessments; and are communicated accordingly. We report all HSW incidents openly, honestly, promptly, accurately and consistently. We promote a strictly no blame culture; the purpose of reporting incidents is to identify root causes, learn lessons and avoid reoccurrences. All incidents are recorded on the HSW reporting system, SafetyNet which is simple to use and easy to access on all desktop and mobile internet devices. Detailed guidance and training are available on our Company Intranet to ensure all those required to use Safety Net are competent to do so. In addition we have nominated SafetyNet champions across the business, who are available to support and help managers and individuals in the use of the system. The HSW Performance and Reporting team are accountable for analysing HSW data, identifying trends and areas for continuous improvement, then providing insight to the business We take an eight step approach to investigations: Step 1 – create a Safety Alert to communicate immediate essential information to the business, Step 2 – gather evidence, Step 3 – create a timeline of events, Step 4 – undertake Root Cause Analysis, we use the five Why’s approach to establish the root causes. We are clear that there may be several root causes to an incident and more than one remedial action to address each root cause, Step 5 – assign and carry out actions , Step 6 – update the company reporting system incident record, Step 7 – communicate and finally,Step 8 – investigation review and sign off. 403-3 Occupational health services Refer to the “Supporting our employees” section of the 2021 SR. Additionally: If individuals are exposed to hazards such as: noise, display screen equipment, hazardous substances, or working at night – dependent on their role – their manager will be prompted to book the individual onto our health surveillance programme. The health surveillance team can be contacted by calling or emailing our external provider. The health surveillance programme is designed to measure the effect of the working environment and the effectiveness of any controls put in place. It protects employees, it protects the company, and it’s also a legal requirement. 403-4 Worker participation, consultation, and communication on occupational health and safety Refer to the “Supporting our employees” section of the 2021 SR. Additionally: We seek input and feedback from all of our colleagues and HSW representatives. We will also commit to ongoing constructive dialogue with our Trade Union members; fostering a joint understanding of HSW needs and helping deliver common solutions that will make our people safe and well. The Company Forum is the medium used for discussing and, where appropriate, reaching agreement on HSW issues which affect the whole of STW. As different parts of the organisation will have different business priorities and issues, there are also a number of Business Forums operating under the umbrella of the Company Forum. We have a number of Safety Improvement Teams (SIT) active across our business. SITs are groups of people who meet regularly to discuss team specific HSW performance and issues, and work to resolve those.. In teams we also have appointed Wellbeing Champions. The Champion works with our Wellbeing team, are a point of contact within the team to share comms and campaigns, but also support the Team Manager in spotting and resolving individual wellbeing issues. The HSW team work closely with all groups, providing regular lead measures relevant to each to ensure they understand performance issues and are working to resolve them. We actively invite participation and feedback from our employees through a number of mediums including the annual engagement survey and behavioural safety surveys. SASB/GRI content index
