short‐circuit has been resolved, the cell will start to cool down. However, the area
has to remain isolated until the cell reaches ambient temperature and is removed
from the area. The temperature of the cell has to be checked periodically using a
remote sensor such as an infra‐red sensor. If the cell remains hot the following
actions must be assessed.
MINIMUM EQUIPMENT REQUIRED:
• Infra‐red temperature probe
• Safety glasses
• Hard hat with impact resistant face visor
• Non‐conductive pliers
• Hand, arm and body protection
PROCEDURE:
• Evacuate the area as soon as abnormal cell temperature has been established.
• Periodically check the temperature of the cell using a remote sensor for the
first two hours or until one of the following cases occur:
– The cell starts to cool down
– The cell vents
– The cell explodes
• If the cell starts cooling, check the temperature every hour until ambient tem‐
perature has been reached.
• If a temperature sensor is not available, do not handle the cell for a minimum
of 24 hours.
• Remove the cell from the work area when ambient temperature has been rea‐
ched and return to normal operations.
• Dispose of the cell in accordance with existing legislation (in the country in
question) on hazardous goods.
• The procedures in cases of venting or explosion are examined in the following
paragraphs.
12.18.1.3.Procedure for handling vented cells
In normal conditions a cell does not show leaks or venting, however a cell may
vent or release substances if the critical temperature is reached or if the protective
glass‐metal seal breaks due to severe mechanical conditions. The severity of the
leak consequent to venting ranges from slight leak around the seal to a violent
leak of substances through the vent. In some cases, if the cell is not plugged, it
