Precautions for Dismantling
Dismantling the Altima Hybrid may be performed like conventional Nissan vehicles, except as noted in these
guidelines.
Spills
The Altima Hybrid contains the same common automotive fluids used in other non-hybrid Nissan vehicles, with
the exception of the Ni-MH electrolyte used in the high voltage battery. The Ni-MH battery electrolyte is a
caustic alkaline (pH 13.5) that is damaging to human tissues. The electrolyte, however, is absorbed in the cell
plates and should not normally spill or leak out even if a battery module is cracked. Both the metal battery case
and the plastic battery modules could be breached if a catastrophic crash occurred.
A diluted boric acid solution or vinegar can be used to neutralize a Ni-MH battery electrolyte spill, similar to the
use of baking soda to neutralize a lead-acid battery electrolyte spill.
NOTE:
Electrolyte leakage from the high voltage battery is unlikely due to the battery construction and the amount of
available electrolyte contained within the Ni-MH modules. Any spillage would not warrant a declaration as a
hazardous material incident. The technician should follow the recommendations as outlined in this dismantling
guide.
In an emergency, Nissan Material Safety Data Sheets (MSDS) are available by contacting:
United States: CHEMTREC at 1-800-424-9300
Canada: CANUTEC at *666 or 1-613-996-6666 (collect)
•
Handle Ni-MH electrolyte spills using the following personal protective equipment:
¾ Splash shield or safety goggles (fold down helmet shields are not acceptable for acid or alkaline
electrolyte spills)
¾ Insulated rubber gloves
¾ Acid-resistant apron
¾ Insulated rubber boots
¾ Insulated rubber mats (for connect/disconnect of high voltage battery)
DANGER:
•
Failure to disable the high voltage electrical system before emergency response procedures are
performed may result in serious injury or death from electrical shock.
•
Failure to disable the low and high voltage electrical systems before emergency response procedures are
performed may result in serious injury or death from the unintentional deployment of the SRS.
•
The Ni-MH battery electrolyte is a caustic alkaline (pH 13.5) that is damaging to human tissues. To avoid
injury by coming in contact with the electrolyte, wear proper personal protective equipment.
WARNING:
•
Never assume that the Altima Hybrid is shut off simply because it is quiet.
•
Always observe the instrument cluster for the READY operation indicator light (green) status to verify
whether the vehicle is on or shut off. The vehicle is shut off when the READY operation indicator light
(green) is off.
•
The use of personal protective equipment (PPE) such as insulated rubber gloves, insulated rubber boots,
and insulated rubber mats must be used when disabling the high voltage electrical system.
DANGER:
•
The Ni-MH battery electrolyte is a caustic alkaline (pH 13.5) that is damaging to human tissues. To
avoid injury by coming in contact with the electrolyte, wear proper personal protective equipment.
