Providing safety measures for workers and external environments are indispensable in R&D activities of the iodine sulfur water-splitting hydrogen production process, since this process uses toxic chemicals as sulfur dioxide, sulfuric acid, iodine and hydriodic acid. One of the R&D subjects is proof of manufacturability of chemical reactors made of practical structural materials and confirmation of the reactors' sound performance in the harsh process conditions. In order to examine the task, test apparatuses of the process are being constructed; the apparatus for a Bunsen reactor has been built and assembled. Capacities of vessels of the apparatus are about 50-150 liter; normal operating pressure will be 0.5 MPa [abs], and that of temperature will be 90 degrees centigrade. Safety measures for the test apparatus, operations, and in abnormal situations were considered prior to the start of the operation. This report summarizes the results of the considerations.
