Looks like a certification of safety inspection sticker for a motor vehicle that is driven on public roadways.
When I'm wrong I go big or, go home.
Is it a sticker of certification of inspection for a
gasoline / petrol or diesel fuel pump?
A meter to measure the consumption of a utility ( electricity ).
Looks like a hoisting system of some sort.
It's the hydrostatic release unit on an inflatable life raft.This device automatically launches the life raft as the ship sinks,if it hasn't already been manually launched.
These devices are required under maritime law because,depending on the emergency,ships can sometimes sink so quickly that there is no time for the crew to launch the life rafts manually.
