About Your Presenter…



Why Innovate?

An Unrivaled Legacy - Based on Trust…1880 Factory Mutual specify sprinklers in mills

1883 Stock Insurance discounts sprinklered risks

1886 New England Insurance Exchange special committee meets to prescribe performance requirements & approve devices

1887 Mutual Fire Insurance Corporation of Manchester create first sprinkler rules

1888 Insurance rates of $0.30 per $100 of risk drop to $0.05 per $100 if sprinklered

1897 First edition of NFPA13


A Proud History of Innovation…

& hydrogen sulfide

• Impingement / Lodgment

• Spray Pattern

• Spray Endurance

• Actual Delivered Density

• Crib Testing

• Full Scale Fire Testing




Innovation:Is It Always Progress?..


New Innovation? - Questions We Should Ask:


New Innovation? - Questions We Should Ask:

Innovate

Don’t

Innovate• Is there a problem here?

• Who benefits?

• Who says it works?

• Technical Support?

• Failure Modes?


Not Innovating? – Questions We Should Ask:

Don’t

Innovate

Innovate

• Are we aware of the latest research?

• Will existing still work with new hazard / risk?

• Are we sure existing reliability is superior?

• Can we still accept current failure modes?

• Will we become more vulnerable?


Evaluating Innovations:

• What problem does it solve?




• Is it better than an existing solution?




• Is it better than an existing solution?

• Who says it will work?


What Problem Does it Solve? Is it better than an existing solution?

Who says it works?

Logistics Industry increasingly favouring Larger & Higher warehouses

• Quick Response

• Commonly used for the protection of hotelbedrooms. Overcomes the need forsprinklers and exposed pipework in thecentre of the room

• 1974 - Testing standards for EC sprinklers were proposed by Underwriters Laboratories

• 1987 EC confirmed in NFPA13 as suitable for Ordinary Hazard

• 1994 EC Sprinklers approved by Factory Mutual

• 2009 CEA 4001EC may be used in LH and OH1 hazards

• 2016 SBF120:8 EC Sprinklers used for Light or Ordinary Hazard according to NFPA classification

• 39 sprinklers per wing

• x3 wings per floor = 117 sprinklers per floor

• X20 floors = 2340 sprinklers total



Why Use EC Sprinklers?

“Sprinkler system or firefighters - neither one is quick enough…”

“In densely packed warehouses, the extinguishing water can get ‘lost’ amid the racks…”

“Fire in the home is a real problem.

Today’s fire sprinkler systems are not designed for domestic use…”



PERCEPTION

REALITY

Some Reasons Given Not to Innovate…


• Existing technology has proven to be effective

• We are already successful doing what we do

• If it’s not broke don’t fix it

• Innovation requires investment = £££

• Why risk our legacy?
