## High Voltage Equipment (>110V) in Batching Plant Installation
*   Focus: Inventory, Risks, and HSE Guidelines for heavy industrial equipment.
*   Context: While sites use 110V, plant installation requires 220V, 400V, and 480V 3-Phase power.

## Industrial Equipment Specifications
*   **Static Welding Machines**: 400V/415V (3-Phase). Risk of fatal shock on primary side; trip hazards from heavy cabling.
*   **Rebar Machinery**: 400V/220V. Risks include high torque crushing and electrical control failures.
*   **Industrial Air Compressors**: 400V (3-Phase). Risks of automatic start/stop and high heat/noise.
*   **Lifting Winches & Hoists**: 400V (3-Phase). Prone to cable damage; phase reversal risk leading to load drops.
*   **Mixer & Conveyor Drives**: 400V-600V (3-Phase). Critical LOTO requirements to prevent fatal entanglement.

## Common Causes of Electrical Incidents
*   **Lack of LOTO**: 35%
*   **Improper Grounding**: 30%
*   **Damaged Insulation/Cords**: 25%
*   **Equipment Failure**: 10%

## Summary of Operational Risks
*   **Fatal Shock**: 400V/415V systems deliver full voltage to ground.
*   **Arc Flash**: High energy levels can cause explosive flashes in distribution boards.
*   **Cable Management**: Heavy armored cables create site traffic hazards.

## Required Controls & Protections
*   **RCD/GFCI**: All circuits >110V must have 30mA protection.
*   **Connectors**: Industrial IP67 rated IEC 60309 (Red=400V, Blue=220V).
*   **Administrative**: Mandatory Permit to Work and Lock Out Tag Out (LOTO) protocols.
