Daily Discussion question submitted from a member:
Small bathrooms can omit a sprinkler under NFPA 13 in some instances where bathroom walls and ceilings (including behind the shower and tub) are non-combustible or limited combustible with a 15-minute thermal barrier rating (NFPA 13 2002 814.8.1.1, 2007-2016 8.15.8.1.1). If the bathroom has a window to the exterior, would it need a sprinkler? Discuss this here. Daily Discussion question submitted from a member:
I wanted to see if you have heard of any great programs, apps, databases, etc. that are appropriate for creating and maintaining panel schedules. We currently use Microsoft Access to collect data and turn it into easy to understand panel schedules for the other fire protection engineers and the maintenance team. Our panel schedules contain info such as how to impair a building (which switch’s to enable/disable), building contact info, a list of all devices and modules, info on all NACs and Power Supplies, sprinkler components and their corresponding alarm device. Microsoft Access is becoming increasingly difficult to maintain and it appears that this program has been put on the back burner for Microsoft. Have you heard about programs that other sites/companies are using? With iPad integration? With the ability to limit who can actually edit the data? Thanks for the help. Discuss this topic here. |
