there is an external short‑circuit and resolve it as soon as possible. After the 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 infrared sensor. If the
cell remains hot the following actions must be assessed.

• Minimum equipment required:

Infrared 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 temperature
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 reached 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 para‑
graphs.

7.26.3.2 Procedure for handling vented cells

In normal conditions a cell does not show leaks or venting, however a cell may vent or relea‑
se 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 may
behave as a projectile.
The electrolyte inside the cell may cause very serious irritation to the respiratory tract, eyes
and skin. In addition, venting may cause the emission of highly corrosive vapours in the
work environment. In this case, all protective equipment suited to limit exposure to toxic
fumes must be available.
