Procedure For Handling Vented Cells - JLG X430AJ Operation And Safety Manual

SECTION 6 - GENERAL SPECIFICATIONS AND OPERATOR MAINTENANCE
Start Procedure;
1. Evacuate the area as soon as abnormal cell tem-
perature has been established.
2. Periodically check 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
3. If the cell starts cooling, check the temperature
every hour until ambient temperature has been
reached.
4. If a temperature sensor is not available, do not
handle the cell for a minimum of 24 hours.
5. Remove cell from the work area when ambient
temperature has been reached and return to nor-
mal operations.
6. Dispose of the cell in accordance with existing leg-
islation (in the country in question) on hazardous
materials.
Procedures in cases of venting or explosion are examined in the
following paragraphs.

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
may behave as a projectile.
Electrolyte inside the cell may cause very serious irritation to
the respiratory tract, eyes and skin. In addition, venting may
cause emission of highly corrosive vapors in the work envi-
ronment. In this case, all protective equipment suited to
limit exposure to toxic fumes must be available.
Minimum Equipment Required;
• Class D fire extinguisher
• Eye protection or face shield
• Respirator with filter for hydrochloric acid and sulphur
dioxide
• Neoprene gloves
• Acid.resistant lab coats
• Baking soda, calcium oxide or acid absorbent in kit form
• Vermiculite
• Plastic bags
