Contractor Health, Safety &Environment Management System( CHSEMS )Doc. No.CHSEMS / A3Issue date20/11/2020Rev # & date10 -20/11/2020Contractors, suppliers and others are key to our business performance, which includes our HSEperformance. The minimum requirements for contractors and subcontractors working for TPSwill be the same as the requirements imposed on all members of the TPS Project Team. Theseprinciples will apply to design, fabrication, and construction, installation commissioning anddecommissioning activities. The capabilities and competencies of contractors to performwork on our behalf shall be assessed prior to awarding the contract.The Project Team has defined the minimum HSE requirements for Contractors and theserequirements are communicated to the contractors before starting the projects. Theminimum HSE requirements should be reviewed and updated as necessary during the Projectlifecycle.Satisfactory Contractor safety performance will be accomplished by encouragingContractors to invest and fully participate in the health and safety of their employees bydeveloping, maintaining, and implementing their own safety programs. A Contractor’s safetyprogram (including health and environmental aspects) will be considered an important factorin determining award of contracts. Concern for employees, communities, and the localenvironment will be a guiding principle in all decisions.We will use only qualified competent Contractors, i.e. Contractors that provide their serviceswith people who are properly trained, well equipped, and efficiently supervised: Contractors must develop, maintain and implement their own HSE programContractors must comply with applicable regulations, standards, policies andrecognized safe work practices, as well as waste management and spill preventionpracticesContractors must provide adequate and correct personal protective equipment andensure their people are trained in its use and that it is used properlyEffective communication and understanding of responsibilities and standards are prerequisitesfor quality Contractor safety. TPS prime responsibility for Contractor safety is to ensure TPSsafety requirements, standard safety practices, potential hazards, and site specific rules andprocedures are communicated to, and understood by, the Contractors prior tocommencement of work. This can be done through the bidding process, master servicesagreements, pre-job meetings, and/or site induction programs.Contractors are responsible for the safety and health of their employees (includingsubcontractors) while in the service of TPS. This includes:Training of their people to a competent level for the work they will be required to perform.Page 6

Pre-qualification of Bidders/ SuppliersThe Project & Procurement team shall pre-qualify and/or select all contractors using theTATA Power Solar Systems Limited HSE Contractor Selection Questionnaire Annexure 1.Contractors will be required to use the same form for subcontractors who will work on theContractor-manage site or TPS site. The completed forms will be reviewed by theProcurement, Project & HSE Team as part of the qualification/bid evaluation process.Also considered in the qualification process: Post-project appraisals from previous jobs, if available. Safety record and HSE reputation. Information gathered during Contractor’s site audits regarding safety programs anddata submitted in the Questionnaire.Contractors who do not meet the minimum health, safety and environmental requirementsand are deemed to have unsatisfactory safety performance shall not be considered forNext step.2. Pre Contract Award Process:The Project/procurement Team will provide potential Contractors the Section 2 of CHSEMSPlan to ensure that they understand the safety principles, goals and objectives, andAdequately address them.Page 7

Contractor Health, Safety &Environment Management System( CHSEMS )Doc. No.CHSEMS / A3Issue date20/11/2020Rev # & date10 -20/11/20203. Contract Award:The Project Team will review these HSE contract requirements with the contractors prior toexecution of the contract to ensure mutual understanding.The Contractor (or Sub-Contractor) shall develop a hazard assessment detailing specifichazards that their employees will be exposed to and/or introduced to during the project, andplanned implemented mitigation activities. This will be reviewed by the Project Team to ensurethat the Contractor has an adequate understanding of the hazards associated with their work.Contractor undertaking as per Annexure 2 shall be taken and copy of same should be sharedwith HSE team.4. Subcontractors:Subcontractors shall be required to meet the same HSE requirements as Primary Contractors.Primary Contractor shall be responsible for the HSE management of its subcontractors,including site orientation and training in HSE systems.Prior to the selection of any subcontractors, Contractor shall undertake a thoroughinvestigation of the subcontractor's HSE practices and identify any differences betweenContractor's HSEMS and subcontractor's HSEMS. All identified areas shall be resolved prior tothe subcontractor commencing Work.All subcontracts shall allow for termination of the subcontract in the event of HSE violations bysubcontractor personnel as per TPS HSE guidelines.5. Post project Assessment:When a contractor’s work has been completed, the Project & HSE Team will evaluate majorcontractors’ proactive HSE initiatives and performance using the Annexure 3 post-projectappraisal form. This appraisal will be viewed as a shared learning and shall be documentedand communicated with the Contractor and TPS as appropriate. Contractors should evaluatethe performance of their Sub-Contractors.Page 8

If equipment is capable of being Locked-out, Contractor’s Personnel shall apply alockout device. A lock clearly and obviously identified as a safety lock shall be used asthe lockout device. Machines or pieces of equipment that cannot be Locked-out shall be Tagged-out. Themachine or equipment shall be affixed with tag, attached to the energy isolatingdevice (switch or valve) together with a secondary protection in place to minimize thehazard to the greatest extent possible. Examples include:o Removal of an isolating circuit elemento Blocking of a controlling switch or;o Opening of an extra disconnecting device.o Personnel posted at location during entire process All potentially hazardous stored or residual energy shall be relieved or otherwiserendered safe in the same manner. When a Tag-out device is used on an energy-isolating device, it shall be attached atthe same location as the energy-isolating device. If this is not possible, the tag shall bePage 22
