battery safety training

1. Battery & Energy Storage Safety SE-ES20-00031 EHS Center for Excellence Jabil Social & Environmental Responsibility

2. At the end of this training, you should be able to: Understand which requirements are applicable to your site Describe the elements required as part of a Battery & Energy Safety program Understand the actions needed to develop, implement, and maintain an effective, written program LEARNING INTENT

3. Remember Your Site procedure Shall cover the below items: Corporate EHS standard - Cover all sections of the corporate standard that apply to your site + Local regulations (country, regional, state, province, etc.) + Divisional requirements, if any + Consensus standard + Site and Customer Requirements, if any Note: If local regulations are more stringent follow the corporate standard plus additional local regulations If local regulations are less stringent follow the corporate standard Adherence to the Jabil 00-ES15-00002 EHS Management System Manual is required REQUIREMENTS FOR SITE LOCAL PROCEDURE

4. This standard addresses the safe handling and use of batteries: I nstalled in products used/purchased by Jabil, such as fork truck batteries, energy storage systems, including battery backup/UPS systems and B atteries that Jabil employees install in products that Jabil manufacturers, including assembly of energy storage systems (ESS). It is applicable to all manner of batteries: Lead Acid, Lithium based (lithium metal, Li-Ion, Li Polymer), Nickel based (Ni-Cd, Ni-Hydride), etc. NOTE : While the standard covers all battery types, no specific, special requirements are identified for Nickel-based batteries. APPLICABILITY

5. A simple definition: A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction. WHAT IS A BATTERY? Source: https://climable.org/batteries

6. The hazards and associated risks at each site differ due to the various types of batteries used or handled and their associated activities. A site-specific risk assessment that addresses the safety, health, environmental and property risks for the use, storage, handling and assembly of batteries and energy storage devices is required. NOTE : Hazards and risks may have already been addressed in the sites existing Risk Assessment. Assessment includes at least the following risks (if applicable): Fire, explosion, and runaway reactions Chemicals (acids, etc.) Spills, airborne releases, etc. Manual handling (heavy lifting, etc.) Disposal RISK ASSESSMENT

7. Fire and explosion hazards Electrical Hazards Stranded or stored energy hazards Overcharging Chemical Physical Thermal runaway BATTERY HAZARDS

8. There are specific general practices that are required for all types of batteries handled at a site. The specific practices address: Handling Storage Charging Fire Ventilation Spills Personal Protective Equipment (PPE) Disposal ALL BATTERIES

9. Types of Lead Acid Batteries (PbSO4) Vented, Wet-cell or Flooded Sealed or VRLA (Valve Regulated Lead–Acid): Sealed For Powered Industrial Truck (PIT) and Automated Guided Vehicles (AGV), Follow the requirements in the Jabil Standard (SE-HS20-00011) and Specification (SE-HS20-00012). For all lead-acid battery types, additional practices are necessary for: Handling Charging Storage Spills PPE LEAD-ACID BATTERIES

10. Types Non-rechargeable (primary) lithium metal batteries Contain lithium metal – need Class D fire extinguishers that contain a copper powder are approved for combating a lithium fire. Rechargeable (secondary) Lithium-ion/Lithium polymer batteries Many different types of lithium-ion batteries Lithium-ion battery: Broad range of chemistries used Electrolyte containing these lithium ions is usually highly volatile and flammable System of integrated components Lithium-ion cells Integration parts (connecting cells together, charger - sometimes) Auxiliary systems (charger, Battery Management System or BMS) LITHIUM-BASED BATTERIES

11. Lithium batteries are generally safe and unlikely to fail Associated Risks: Fire, Explosion from: Over charging or discharging, Short circuits, Physical damage, electrolyte leakage Excessively hot storage and, for multiple cells in a pack, poor electrical connections, faulty BMS Thermal runaway. the excessive heat in one cells, creates heat that involves additional cells, which can result in heat increase, off gassing, swelling, fire and explosion. Fire or an explosion, can result in burns, toxic chemical exposure and pollution due to the battery rupturing. HAZARDS

12. For Lithium battery types, additional practices are necessary for: Handling Charging Storage Fire Disposal Lithium Batteries

13. For larger Lithium-ion batteries, additional practices are necessary for Handling Charging Storage Ventilation Fire Emergency Response Lithium-ion Batteries: Large types

14. Energy Storage System (ESS): Installed Locate Energy Storage Systems (ESS) within one of the areas, listed in order of preference (as shown in figure) Place the ESS in an area within visible range of personnel or monitored by CCTV. Conduct a Hazard Mitigation Analysis (HMA) for lithium-ion ESS installations that exceed 600 kWh (2,160 MJ) when located: outdoors in open parking garages, on rooftops of buildings, and for mobile ESS equipment. For Energy Storage System (ESS) unit(s) located indoors, provide automatic sprinkler protection.

15. Training Train all employees in the hazards associated with batteries and the required procedures, practices, and work instructions for the safe handling, charging, storage and disposal Specialized training may be required for specific activities Review & Audits Review, audit and validate effectiveness of the local procedures and determine preparedness in the event of an emergency related to batteries. Recordkeeping Retain records according to the Jabil Records Management Policy and applicable regulatory requirements. ADDITIONAL REQUIREMENTS
