insurance company in the world What makes FM Global unique? What makes FM Global unique?
– Philosophy – Majority of loss is preventable– Single Focus – Highly Protected Risk (HPR)– Research & Engineeringg g
Supporting Property Loss PreventionSupporting Property Loss Prevention
Mission StatementMission StatementFM Approvals approves and certifies products pp pp pand services with unique focus on:
Objectively testing property loss preventionproducts and services and certifying those that meet rigorous loss prevention standards;
Encouraging the development and use of Approved products and services that improve and
d t l ti tiadvance property loss prevention practices.
Hi tHistory
1897 1940s 1999 2006
1897 - Approved Electrical Fittings published by Inspection Department of the Associated Factory Mutual Fire Insurance CompaniesFactory Mutual Fire Insurance Companies. Dated June 1897.
We offer Product Certification in 3 key areas Fire Protection Equipment

We offer Product Certification in 3 key areas
−Sprinklers−Traditional fire protection equipment−Fire pumps and related equipmentFire pumps and related equipment−Special-protection extinguishing systems
Electrical Equipment q p−Equipment for hazardous locations−Fire alarm and signaling systems
Building Materials−Roofing products
Fi t ti d fi t d b ildi t i l−Fire-protective and fire-rated building materials−Other property loss prevention products
H d L ti C tifi tiHazardous Location Certification There are many types of protection that can There are many types of protection that can
make a product suitable for use in a specific area classification:area classification: – Explosionproof

Ignition In Hazardous Locations
H d l ti t d d f th Hazardous location standards focus on the prevention of an ignition by eliminating one or more of the three elementsmore of the three elements
Methods to eliminate an element:
Oxidizer = Purging with Inert Gas Fuel = Encapsulation Fuel = Encapsulation Ignition = Intrinsic Safety
There are many others

FM Approvals’ Recommendations
1. Require the same margin of safety for all ESE used in the same area.
2. Require suitability for a specific area q y pclassification rather than a specific protection method.
