High-voltage battery
Storage of high-voltage batteries which are
safe for transport in storage facilities
without sprinkler protection
Due to fire protection requirements, if no sprin-
kler protection system is installed, high-voltage
batteries should wherever possible always be
stored in specially partitioned fire-resistant
rooms of category F90. Alternatively, individual
batteries can be stored in fire-resistant
hazardous goods cabinets of category F90 as long
as no other materials are stored in them. If there
is no appropriate facility in the building, the
batteries must be stored outside of the building at
a distance of more than 5 m from other buildings
or combustible materials. The following points
must also be observed for storage outside the
building:
• Presence of weather protection (roof) to
protect against wet weather or direct sunlight
• Liquid-resistant ground surface or collecting
pan
• Protection from access by unauthorised
persons

Handling and storage of high-voltage
batteries which are not safe for transport
High-voltage batteries which are damaged during
operation or an accident may represent a hazard
to their surroundings depending on the level of
damage. In the event of fire or smoke formation,
the fire department must be informed immediately
and a safe distance must be maintained. If the risk
of acute danger can be ruled out, a high-voltage
battery which has been diagnosed as not safe for
transport may only be removed from a vehicle
after consultation with the relevant MPC/general
distributor and after provision of a special
container.
Until removal is carried out, the vehicle must,
where possible, be parked outside by a qualified
employee of the technical field service (TAD) or a
qualified mechanic. It is important to ensure that
any electrolyte which escapes cannot enter the
soil by parking the vehicle over an impermeable
floor/ground surface or a collecting pan.
High-voltage batteries which are not safe for
transport are stored in a leakproof metal
container which is half-filled with vermiculite
(non-combustible, absorbs escaping electrolyte).
