Abstract:
A method and safety device for use in accessing confined spaces that incorporates atmospheric safety monitoring and alarm annunciation into a physical access device/mechanism for the purpose of preventing the human confined space entrant from entering a confined space containing a hazardous atmosphere.

Claim (Index 1):
A confined space failsafe access system comprising:\n said confined space having an entrance port; apparatus to facilitate entry of a worker into said confined space extending through said entrance port into said confined space; a first gas detecting sensor within said confined space for detecting a dangerous condition, said sensor mounted on a lower portion of said entry apparatus; an alarm status annunciator module outside of said confined space communicating with said sensor for broadcasting whether environment within said confined space is safe or unsafe for entry by said worker; and, a second active dormant sensor with feedback to monitor active access by an individual into said confined space.
