Attention must also be paid to the area surrounding the tank because it may present other hazards or complicate a rescue should one become necessary.
Floating roof tanks safety.
Floating roof tank is which the roof floats directly on top of the product with no vapour space and eliminating the possibility of flammable atmosphere.
Floating roof tanks are commonly protected against lightning ignition by bonding the floating roof to the seal shoes at no less than 3m 10ft intervals use of insulating sections in the hanging linkages covering sharp points on hangers with insulating materials and installation of electrical bond straps across each pinned hanger joint.
Internal floating roof tank can be used to store gasoline jet fuel and other volatile oil and liquid chemicals like aldehydes alcohols methanol ethanol ketones acetone benzene benzene toluene xylene styrene.

This safety notice describes the potential hazards relating to the specification inspection and maintenance of external floating roofs for storage tanks built to bs 2654 1 bs en 14015 2 and api 650 3 there has been a recent incident along with findings from further investigation that suggest the examination and maintenance of floating roofs is not given sufficiently priority.
After all failure of a roof can lead to a loss of containment peeling back the layers of protection and unlocking the door to a major accident.

So let s break down the safety notice.
This is important as heavy rainfall with low roof levels could lead to slow.
For this presentation michael focused on fixed roof tanks.
