Abstract

Sealable plastic bags containing fluorochemical fluids are suggested as one-way transportation covers for mobile devices in explosion endangered areas. The steam pressure of evaporating fluorochemical fluid replaces the air molecules before closing the plastic bag and an explosive gas mixture is prohibited. The fluorochemical fluid is provided by a small reservoir inside the bag and can be released by crushing the reservoir with the fingers.

Explosion Protection Cover for Mobile Electronic Devices Sealable plastic bags containing fluorochemical fluids are suggested as one-way transportation covers for mobile devices in explosion endangered areas. The steam pressure of evaporating fluorochemical fluid replaces the air molecules before closing the plastic bag and an explosive gas mixture is prohibited. The fluorochemical fluid is provided by a small reservoir inside the bag and can be released by crushing the reservoir with the fingers.

Background Existing explosion protection systems for electronic devices fulfill two functions: to prohibit explosion induced by electronic activity inside the device and to exclude exterior sparks when the device is dropped in explosive environment. In both cases a spark starts the ignition of an explosive atmosphere. Typically only special equipment is allowed inside explosion endangered surroundings. The devices are e.g. operated at over pressure of special gas which replaces the oxygen containing air inside and have soft covers to protect sparks. The explosion protection system described herein solves these problems, and is appropriate for all electronic equipment (e.g. mobile phones) that are transported and operated inside explosion endangered environments.

Description This paper describes a cheap and easy-to-use protection cover for all electronic devices and makes special equipment superfluous. The device, e.g. a smart phone, is put into a soft resealable plastic bag (Figs. 1 and 2). The air is squeezed out of the bag (Fig. 3) and a reservoir with fluorochemical fluid is compressed and burst by pressing two fingers on it (Fig. 4). The fluid is...
