Germanium (GeH4) properties

germanium tetrahydride ( GeH4 ) – most commonly germane known as – is the most commonly used form of germanium in industries. Many industrial processes have been created to produce this gas. It is mostly used to produce high-performance integrated circuits in the semiconductor industry, photovoltaic sensor technologies and space applications.

Significant effects on health

At normal temperature and pressure, germane (GeH4) It is colorless, heavier than air and to a strong odor has . This is extremely flammable The gas (H220) may explode when heated (H280). very much when inhaled toxic And it is fatal (H330) and is irritating to eyes, skin and respiratory tract. It can even affect the blood and can damage blood cells .

Germane gas detector – GeH4 or Germanium tetrahydride

Despite its pungent odor, it is only a germane gas detector can accurately measure concentrations of this gas. Even if it were a flammable gas and could explode, an explosiveness (LEL) monitoring would be pointless as this gas is highly toxic. Therefore, ppm or ppb for optimum security germane gas detection devices or complete systems recommended to use

GeH4 respiratory protection – Germane

Since Germane is highly irritating to the eyes, use it only for short interventions. full face mask or B-P3 combined filter A much more comfortable one equipped with powered air breathing apparatus It is recommended to use . In case of high concentration levels exceeding 60 times the OEL, use of a self-contained breathing apparatus (SCBA) or an airway system is required.
