Easily Accessing Hazardous-Event Logs
Monday, November 23rd, 2009
One of the gas detectors near a storage tank sends an alert that a leaking flange has burped out some methane gas. The event must be verified and the possible hazardous condition corrected. Quick access to event logs stored in the gas detector’s memory or in the safety system’s database can provide the information necessary to better understand the event and thereby ensure proper repairs.
A data log stored in a safety system, accessible by local or remote PC, provides critical information such as timestamp and location for all events. Similar information is available directly from many field devices. To retrieve the information, a HART Handheld device can be used. But that is not necessary. (more…)
Under day-to-day conditions, people cannot see, smell, or taste the presence of hydrogen gas. Hydrogen, however, is very flammable and requires only a small amount of energy to ignite. In fact, if leaking from a pipe at a high enough pressure, hydrogen gas can self ignite without the aid of an external energy source.
