What is the difference between sections 700 and 701?  700 says 'required facilities' and 701 says 'legally required'.  I think 702 applies to us (warehouse and small manufacturing space), but I want to be sure I don't miss something.

The fire's cause is believed to be… (Show more)

In  the 101 life safety code , specifically the section for hazardous areas ( 7.11.6)  it is mentioned  that exit devices may be allowed for emergency exit doors, and I understood that  specifically panic devices where required as a must  for emergency exit doors.  Is it appropriate to leave the door open, just with a pull handle and push plate or… (Show more)

NFPA 13 and omission of sprinkler system: We are in the process of building a pyrolysis plant where pyrolysis gas and carbon black are by product.  The fire from both cannot be extinguished by water, and in addition the use of water directly on the fire will cause additional hazards.  A foam system is needed for dealing with the fires.… (Show more)

I work as an outsourced IT HelpDesk position in a school district that wants us to install wire molding to conceal extension cords and Ethernet cables. Ethernet cables yeah sure that's fine they are under 50 volts, but as I understand extension cords are not supposed to be used in place of a permanent outlet especially if it is in the ceiling. The… (Show more)

Hi  I have a question regarding the distance from the hsw sprinkler to a ventilation outlet that is placed about 25mm from the sprinkler head. The sprinkler deflector is not obstructed by the ventilation. But my concern is that the air will cool the sprinkler so much that the sprinkler activation will be delayed. Is this ok? I can't find anything… (Show more)

Little has been done from a regulatory standpoint to ensure that the kind of catastrophic disaster that rocked the town of West, Texas, five years ago doesn’t happen again. That’s the assessment of at least one expert on the fifth anniversary of a fire and explosion at the West Fertilizer plant that killed 15 people and damaged or destroyed… (Show more)

I am an electrical novice.   In and industrial setting, is it required by NFPA 70/70E to lockout a 120v standard breaker (like a household breaker), where the breaker has not been designed to take a lock? Is a tagout device acceptable for standard 120v breakers? Does it matter if the equipment was designed pre- or post-1990?

See attached sketch for fire pump controller neutral. Fire pump controller has the service disconnecting means and transfer switch. The phase conductors on the normal side will be tapped in a separate section at the main switchboard. Since this is a service, per 250.24(c) the grounded conductor (neutral) needs to terminate at the service switch… (Show more)

Just last week the NFPA Fire & Life Safety Policy Institute released a report on Wide Variations in State Adoption of the NEC® Reveal Neglect of Electrical Safety. Rather than “neglect” though, perhaps “actively opposing” would be a better way to state it. Or, at least, this might better capture the statements and actions of some in the Kentucky… (Show more)

I am a apprentice and recently we ran 2-2-2 AL wire from a main panel on a grain bin under ground in schedule 80 PVC to a cow barn but we did not run a ground conducter with the current carrying wire. I asked if this was correct and my employer advised. Grounded neutral conductors serving another building from a main building: Sec. 250-32(b)(2).… (Show more)
