BESS Commissioning SWMS
Battery energy storage system commissioning — HV DC energisation, arc-flash, thermal runaway controls, state-based BESS permit requirements, and grid connection sign-off.
SWMS variants reference your state’s WHS legislation. Instant download after payment.
Commissioning of battery energy storage systems involves HV DC string energisation, arc-flash exposure, thermal runaway risk, and grid connection sign-off. Under WHS Regulation 2017 (NSW) and equivalents, this work triggers HRCW notification, electrical permits, and AS/NZS 5139:2019 compliance before any switching or load testing occurs.
Hazards identified
3 hazards covered, sorted by priority.
Severe burns, blindness, fatality
Toxic gas release, explosion, multi-fatality
Electrocution; DC cannot be let go
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Isolate, lock-out, verify zero-volts per AS/NZS 4836; insulated DC-rated tools and Cat 2 arc-flash PPE.
- 2Pre-commissioning thermal scan, gas detection, and exclusion zone per NSW BESS COP 2024 staged energisation sequence.
- 3Licensed electrical worker performs switching under permit; emergency shutdown and Class D extinguisher on standby.
Applicable Codes of Practice
Battery system safety, installation, commissioning requirements
State-specific BESS commissioning and permit requirements
High-Risk Construction Work triggered
Lithium thermal runaway and flammable electrolyte vapour create explosion atmosphere during fault conditions.
DC string voltages exceed 120V DC live during commissioning switching and verification.
Written SWMS mandatory before work starts; PCBU penalties to $30,000.
