Mezzanine Floors and Fire Protection

What is mezzanine floor fire protection and why is it necessary?

So called ‘fire protection’ is effectively insulation of the mezzanine floor steelwork to prevent it from heating up quickly in a fire. Unprotected steelwork heats up quickly and can suddenly collapse. Fire protection is specified for a certain period of time such as ‘half hour’, ‘1 hour’, ‘2 hour’ or ‘4 hour’. The time period refers to the time that the protected elements remain structurally sound in the event of a fire. The fire protection required for different parts of buildings is specified within the Building Regulations part B.

Fire protecting building elements in accordance with the regulations is a statutory requirement, protecting lives and property and enabling the fire brigade to assess how long they can safely fight a fire before a risk of collapse.

Providing fire protection to mezzanine floors is also referred to as ‘fire rating’ them, and a mezzanine floor fitted with fire protection may be referred to as ‘fire rated’.

What is the best material used to extinguish fires?

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.

Class vs Pounds The Rating of fittings

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.

Residential Fire Sprinkler System Advantages

This is a guest post by Ryan J Smith. If you want to Guest Post, check out the Guidelines here.

Fire sprinklers have been used in the protection of many business establishments. But lately these fire protection systems have also gained popularity among home builders and home buyers alike. So what leads people to install fire sprinklers in their residences even if they have already installed smoke alarms? It is because smoke alarms merely alert occupants to a spreading fire in the house, but these devices cannot suppress it. Fire sprinklers on the other hand have proven to be very effective in controlling a fire and protecting people from its associated dangers.

According to the National Fire Protection Association, there were about 396,000 residential fires during 2005 in the United States. These fires had caused 3,055 civilian fire fatalities, 13, 825 civilian fire physical injuries, and $6.9 billion in property losses.

Studies conducted by the Federal Emergency Management Agency’s United States Fire Administration show that thousands of lives could have been saved if residential fire sprinklers had been installed in those burned homes. The installation of a fire sprinkler system could have also prevented most of the fire related injuries and substantially reduced property damage.

Residential fire sprinklers are therefore very beneficial to both people’s lives and properties. The advantages of these fire protection systems are further detailed below:
