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.

It seems that I must have missed something in the 23 years I've been in Code Enforcement. Since when has it been required for a smoke detector to be in the pit of the elevator? This is absolutely insane. We've had more nuisance alarms recently in new buildings. One is a 4 story nursing home, that the alarm has gone off 4 times. The alarm company changed the detector and it been good now. However there is still dirt, moisture, humidity, etc. All the things that smoke detectors don’t like. I've looked and Googled it and have only come up with a heat detector within 24" of the sprinkler head, which I understand. I know smoke rises so why isn't the top of the shaft sufficient? I feel we are going backwards. Discuss this topic here. |
