Abstract
A combined solution is presented for minimising the safety hazards associated with closed cycle cryostats described in Swainson & Cranswick (2010) J. Appl. Cryst. 43, 206-210. The initial solution is to install a vent tube witn one open end deep inside the sample space and a pressure relief valve at the top. This solution works for either a cryogen or cryogen free (closed cycle) system. The second approach that can be combined with the first and is applicable to cryogen free cryostats involves electrically interlocking the closed cycle refrigerator compressor to the sample space, so that the system cannot be cooled in the presence of a leak path to air.Citation
