Mechanical Damage. The mechani- cal damage of batteries may result in internal short circuits and fires. The housing may be damaged by manufac- turing defects (e.g. improper assembly of individual battery components), me- chanical stress, or overpressure within the cell. Overpressure usually develops when a cell is overheated as a result of an overload, a short circuit, or an over- charge. Secondary thermal stress: Exterior thermal stress (caused by thermal radi- ation in case of fires, for example) may make components (e.g. separators) of lithium batteries melt, resulting in a short circuit, which, in turn, may easily cause a fire. External short circuit: When the two poles of a battery are connected to one another (e.g. by a metal object), this re- sults in an external short circuit. Internal short circuit caused by a cell failure or crash: Among the main reasons for internal short circuits are manufacturing defects arising in the course of the production of lithium cells. If metal particles or other conduc- tive impurities are enclosed between the separator and the electrode in the course of the manufacturing process, for example, this may result in a local defect of the separator film during op- eration and, thus, in an internal short circuit. The so-called “run effect” may result in microscopic separator defects developing into extensive cracks in the film material within days or weeks; the increase in temperature caused by the short circuit, which may seem insignifi- cant at first (because it is just local), may then develop exponentially, resulting in a thermal runaway. In everyday usage, internal short circuits often remain un- noticed until they suddenly cause fires after longer operation times. Overcharge: A cell or battery is charged to a level exceeding the end-of-charge voltage specified by the manufactur- er. The fully charged cell is not able to store the energy supplied from the socket; consequently, the overcharged cell or battery heats up. Inside the cell, the organic electrolyte fluid may start evaporating and the crystalline layered structure may start disintegrating; in combination with a strongly exother- mic reaction, this may lead to the re- lease of elemental oxygen (oxidizing!). The strong local temperature increase in the course of this process may start a fire and, under certain circumstances, may cause an “explosive” discharge reaction. In addition, a disposition of metallic lithium on the anode may oc- cur (so-called “lithium plating”). Con- seq...

Mechanical Damage. This applies to trees greater than 8 feet tall with a diameter less than 10 inches at DBH with one or more of the following injuries:

Mechanical Damage. Any damage caused to the vehicle during the hire is the responsibility of the Hirer as set out in the standard Terms and Conditions of Hire. For use at Festivals you should particularly note that if the vehicle becomes stuck in the camping fields or access roads you should obtain a tow out of the field, this would be at your own expense and is not covered through the breakdown cover which we have provided. Should you attempt to free the vehicle yourself and burn out the clutch or cause other damage to the vehicle in any way, you will be responsible for the entire cost of repairs and for the following hire periods and associated costs of cancelling hires that may have been booked while the vehicle is unable to be hired out due to repairs are being arranged and/or carried out. The cost could be significant, running into many thousands of pounds. The vehicle is not insured for mechanical damage and/or failure and associated costs and your deposit is unlikely to cover the costs We will seek to recover any and all costs from you, through the courts if necessary.
