Extra Margin Emergency Escape Mask

The Extra Margin Emergency Escape Mask was a portable safety device for both adults and children.  It could be put on in seconds, providing immediate protection from hazards usually encountered in a fire.  The mask's built-in filter was shown to be effective for up to 20 minutes.  This example was made by a Japanese company called Emergency Devices in 1981.
