| BOILER
COVERAGE |
| A boiler coverage policy will pay for a loss caused by, or resulting from, an explosion of any steam boiler, electric steam generator, steam piping, steam turbine, steam engine, gas turbine, or moving/rotating machinery caused by centrifugal force or mechanical breakdown.
The boiler and machinery policy provides coverage for the same premises as a property policy. However, the cause of a loss is what makes boiler and machinery coverage unique and necessary...it covers causes that standard property policies do not.
To trigger coverage under a boiler and machinery policy, there must be an accident to an object while the object is in use or connected and ready for use. An accident is defined, basically, as a sudden and accidental breakdown of an “object” which results in physical damage to the object and necessitates repair or replacement.
“Objects” can be defined either by specific types, such as boilers, unfired vessels, air conditioning units, mechanical objects, electrical equipment, turbines, etc. Or, they can be defined using a comprehensive definition. Which picks up virtually all types of equipment defined by the specific object groups, but under a single broad definition.
