What is the best material available to man to use in fire protection systems? Oxidane, Hydrogen oxide, Dihydrogen monoxide, Hydrogen Hydroxide, Hydroxylic acid, Hydroxic acid H2O or just plain old WATER? Actually all the items listed are just water!
We are in the business of putting water on fires. Either as a fire sprinkler contractor or fire fighter. We both employ specialized equipment whose only purpose is to get water on the fire in many different ways.
What makes water such a great fire fighting medium? Both as liquid water and as vaporized steam, water has properties that make it good for firefighting. Water has a high capacity for holding heat. Thus when applied to a fire, water carries the heat away and reduces the fuel’s temperature. When water absorbs enough heat it turns to steam which is effective in displacing oxygen and starving the fire.
What is the pressure rating of a Class 125 fitting? What is the pressure rating of a Class 250 fitting? The answer to both of those questions is the same. It depends!
One thing that’s been a problem over the years in dealing with fittings is the nomenclature used. For years we called our cast iron fittings 175 pound fittings. And then when we needed higher pressures we called for 300 pound fittings. I’ve had plenty of discussions with engineers over what fittings to use due to a general misunderstanding of how fittings are rated. I learned to start by trying to educate people about this subject.
I’m sure everyone is familiar with glass bulb fire sprinklers. So much so in fact that they may not be familiar with fusible link sprinklers. The glass bulb is considered the standard type of sprinkler operation today. But, us older folks in the sprinkler community remember a time when the fusible link sprinklers were the standard. But did you know that the glass bulb sprinkler has been around over 80 years!
New North Carolina Laws in Effect February, 2010
What You Need to Know Right Now!
July 4th fireworks are just around the corner and many jurisdictions have special events between now and then that may involve pyrotechnics. As a result of last year’s tragic event in NC with a fireworks display, the 2009 legislature enacted requirements (NCGS 14-410) that anyone who discharges or operates outdoor pyrotechnics or proximate (indoor) pyrotechnics must attend a training course and earn a pyrotechnics operator permit from the Office of State Fire Marshal before conducting a display in NC. The last thing you need is to get to the day of the event and learn that there are new laws that affect your ability to issue a permit for the event and no time left for compliance.
It is important to note that these new laws work in conjunction with existing laws that involve additional requirements:
– Permits for use of Pyrotechnics can only be issued by a NC Certified Level III Fire Prevention Code Inspector.
– In addition to the permit for code compliance, the event must be approved in writing by the county commissioners or city board as detailed in NCGS 14-413.
For your convenience and preparation for pyrotechnic events in your jurisdiction, checklists has been provided on our website at: Go Here.
