NIOSH/CDC  does not appear to have established an IDLH (30 minute escape) value for germane.  Does anyone have a working IDLH value for germane?  I am looking for an IDLH value for germane (GeH4)- defined by OSHA as

An atmospheric concentration of any toxic, corrosive or asphyxiant substance that poses an immediate threat to life or would cause irreversible or delayed adverse health effects or would interfere with an individual's ability to escape from a dangerous atmosphere. [29 CFR* 1910.120]. 

with regards,
