A quality sprinkler system is critical in safeguarding a business or residential building from the devastation that a fire can cause.
In the UK, the British Automatic Fire Sprinkler Association, known as BAFSA, is responsible for over 85% of all sprinkler installations in the United Kingdom. Their goal is to keep people informed about the benefits of having a sprinkler system, as well as being a significant stakeholder in fire safely legislation and standards.
Sprinklers in the UK must be installed to a certain standard. Domestic and residential buildings currently must comply with standard BS 9251: 2005, whilst the commercial and industrial building equivalent is standard BS EN12845: 2004. These safety and security legislations are scheduled to be revised in the near future as part of an on-going review of fire safety guidelines in the UK.

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 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.
