3.0  INSPECTING THE BATTERY SHIPMENT

3.1  General

Precautions have been taken to pack the battery units, individual cells or cabinets containing
batteries for shipment to ensure their safe arrival. However, upon receipt, you should inspect
for evidence of damage that may have occurred during transit.

3.2  Visible External Damage

IMMEDIATELY upon delivery (while the carrier representative is still on-site) inventory all
materials against the Bill of Lading and inspect for visible external damage.

Check material quantities received against the Bill of Lading, including the number of 
battery pallets and the number of accessory boxes.

Note any:

damage to packing material and/or product.

wetness or stains, indicating electrolyte leakage.

If damage is noted:

1.

Make a descriptive notation on the delivery receipt before signing.

2.

Request an inspection by the carrier.

3.

File a damage report.

WARNING

During inspections, take precautions against electrical shock. You are
handling LIVE batteries.
