A complaint filed with the agency shows that on Oct. 23, the inflator on a 2014 X3 exploded, shooting a large gold-colored metal disc that a surgeon had to remove from the driver''s lung. Takata used volatile ammonium nitrate to create a small explosion to inflate air bags in a crash.
The Safety Dangers of Hydraulic Accumulators
An accumulator is a storage device in a hydraulic circuit. It is the hydraulic equivalent of a capacitor in an electrical circuit. The two most common kinds of accumulators are the bladder and piston types. The bladder (Figure 1) is nothing more than a rubber balloon that separates the hydraulic oil from the dry nitrogen.

Back to Basics: Accumulators | Power & Motion
The nitrogen charge in this case is usually kept 5% below the working pressure to ensure the accumulator is out of the circuit except during pressure spikes. Bladder-type accumulators work best at this because of their fast responses to pressure changes, so long as the maximum spike pressure doesn''t exceed four times the
