					Act as a Battery Safety Engineer and High-Voltage Test Facility Manager.
Your TASK is to identify potential hazards and suggest mitigation measures for a test setup involving a High-Voltage (HV) battery.
The battery is specified by `{battery_chemistry_and_voltage}` (e.g.
 'Lithium-ion NMC
 400V nominal
 50Ah'
 'LiFePO4
 800V system
 200kW peak').
The test involves `{test_type_and_max_current_or_power}` (e.g.
 'Charge/Discharge Cycling up to 1C/100A'
 'Short Circuit Test with fault current limiter'
 'Performance testing at 150kW peak power').
The test occurs in `{test_environment_description}` (e.g.
 'Dedicated battery test cell with fire suppression and ventilation'
 'University lab bench with basic safety equipment'
 'Outdoor test rig').

**HAZARD ANALYSIS AND MITIGATION MEASURES (Markdown format):**

**Test Setup Context:**
*   **Battery**: `{battery_chemistry_and_voltage}`
*   **Test Type**: `{test_type_and_max_current_or_power}`
*   **Environment**: `{test_environment_description}`

**I. Electrical Hazards:**
    *   **1. High Voltage Shock/Electrocution:**
        *   **Hazard**: Direct contact with HV terminals
 busbars
 or exposed conductors (`{battery_chemistry_and_voltage}` implies lethal voltages).
        *   **Mitigation**:
            *   `[ ]` Use appropriately rated and insulated tools
 probes
 and connectors.
            *   `[ ]` Ensure all HV connections are shrouded or located within an interlocked safety enclosure.
            *   `[ ]` Wear certified HV insulating gloves and face shield/safety glasses.
            *   `[ ]` Implement clear lockout/tagout (LOTO) procedures for connecting/disconnecting the battery.
            *   `[ ]` Use a "one-hand rule" when working near potentially live circuits if enclosure is open (expert procedure).
            *   `[ ]` Ensure availability and proper function of safety interlocks on test fixtures/enclosures.
    *   **2. Arc Flash / Arc Blast:**
        *   **Hazard**: High-energy discharge due to short circuits
 accidental tool contact
 or insulation failure
 causing severe burns
 pressure waves
 and shrapnel.
        *   **Mitigation**:
            *   `[ ]` Perform an arc flash hazard assessment if current/energy levels from `{test_type_and_max_current_or_power}` are high.
            *   `[ ]` Wear appropriate Arc Flash PPE (suit
 hood
 gloves) if assessment dictates.
            *   `[ ]` Use non-conductive barriers and maintain safe approach distances.
            *   `[ ]` Ensure test equipment (e.g.
 power supplies
 loads) has fast-acting overcurrent protection.
            *   `[ ]` Implement current-limiting resistors or fuses in test setup where appropriate
 especially for `{test_type_and_max_current_or_power}` like short circuit tests.
    *   **3. Stored Energy / Unexpected Energization:**
        *   **Hazard**: Battery remains energized even when disconnected. Capacitors in test equipment can store charge.
        *   **Mitigation**:
            *   `[ ]` Always treat batteries as live unless proven otherwise.
            *   `[ ]` Safely discharge any capacitors in the test setup and in the DUT (if applicable) before handling.
            *   `[ ]` Implement clear power-up/power-down sequences.

**II. Thermal Hazards:**
    *   **1. Overheating / Thermal Runaway (especially for Lithium-ion `{battery_chemistry_and_voltage}`):**
        *   **Hazard**: Excessive heat generation during high current `{test_type_and_max_current_or_power}`
 internal short circuits
 or cell failure
 leading to fire
 smoke
 and explosion.
        *   **Mitigation**:
            *   `[ ]` Closely monitor battery cell/module temperatures using thermocouples or IR cameras.
            *   `[ ]` Implement over-temperature protection in the test script/equipment to stop test and isolate battery.
            *   `[ ]` Ensure adequate cooling/ventilation for the battery as per its specification
 especially in the `{test_environment_description}`.
            *   `[ ]` For Li-ion
 have appropriate fire suppression system for Class D fires or as recommended for `{battery_chemistry_and_voltage}` (e.g.
 specialized extinguishers
 water deluge IF safe for setup
 containment vessel). Confirm based on `{test_environment_description}` capabilities.
            *   `[ ]` Maintain safe spacing from flammable materials.

**III. Chemical Hazards (Relevant to `{battery_chemistry_and_voltage}`):**
    *   **1. Electrolyte Leakage / Venting:**
        *   **Hazard**: Leakage of corrosive
 flammable
 or toxic electrolyte. Venting of flammable/toxic gases during overcharge/over-discharge/thermal event.
        *   **Mitigation**:
            *   `[ ]` Wear appropriate chemical-resistant gloves and eye protection if handling potentially leaky cells/modules.
            *   `[ ]` Ensure good ventilation in the `{test_environment_description}` to disperse any vented gases. Consider gas detection systems.
            *   `[ ]` Have spill control kits available appropriate for the electrolyte type.
            *   `[ ]` Understand the specific hazards of `{battery_chemistry_and_voltage}` electrolyte.

        *   **Mitigation**:
            *   `[ ]` Use appropriate lifting aids for heavy batteries.
            *   `[ ]` Ensure secure mounting and fixtures for the battery during test.
    *   **2. Projectiles (in case of cell rupture/explosion):**
        *   **Hazard**: High-energy failure can eject parts of the battery or test fixture.
        *   **Mitigation**:
            *   `[ ]` Use a robust safety enclosure or test cell designed to contain potential explosions/projectiles
 especially for abusive `{test_type_and_max_current_or_power}`.
            *   `[ ]` Maintain safe viewing distances or use remote monitoring.

**V. General Procedural & Environmental Safety:**
    *   `[ ]` **Emergency Plan**: Ensure an emergency shutdown procedure is established and all personnel are trained. Know location of emergency exits
 E-stops
 fire extinguishers.
    *   `[ ]` **Training**: Only personnel trained in HV safety and specific battery handling/test procedures should conduct tests.
    *   `[ ]` **Two-Person Rule**: Consider a two-person rule for HV operations
 especially during setup and initial runs.
    *   `[ ]` **Clear Signage**: Post clear warning signs indicating HV test area

**IMPORTANT**: This list is not exhaustive. A thorough risk assessment specific to the exact `{battery_chemistry_and_voltage}` characteristics
 detailed test plan for `{test_type_and_max_current_or_power}`
 and `{test_environment_description}` conditions MUST be performed. Always follow manufacturer guidelines and relevant safety standards (e.g.
 ISO
 IEC
 UL
 NFPA).
