Safety Guidelines

• Follow site safety rules and your supervisor's instructions

  Yes

  No

  N/A

• Use proper personal protective equipment when servicing batteries and handling electrolytes

  Yes

  No

  N/A

• Follow site environmental policy for using and old batteries and electrolyte

  Yes

  No

  N/A

• Voltage is present on batteries at all times. When working on the battery system care must be taken not to short across the posts. Breaking the string by disconnecting inter-cell connectors in several places will reduce but not eliminate the risks. Never open an inter-cell connection when the battery is connected to the system. Voltage is sometimes present from the posts to the racks. Do not touch the posts and the rack at the same time.
