I would expect it is proper to have a latch AND a good seal. The
whole purpose of a propane locker is to send vapour (leak) overboard.
If a large leak escapes through an improper seal then you have a
potential path to the interior via the companionway. Not good.
As Chuck points out, a propane tank explodes due to overheating
beyond the capacity of a relief valve. They don't just blow up like
an Atomic 4 might. <TIC> <VBG> <insert other Wally type qualifications>

No latch on the propane locker?
This sounds good at first, until you question what would cause a
propane tank to explode. The tank has a pressure relief plug and
relief valve built into the valve. I think a tank explosion would
need direct flame, or a spark near a leak near the tank, direct
flame for a period of time, or a hot bullet.
I was curious so checked Defender cataloge and see their five
models, all have latches. Maybe it's safer to protect the tank from
exposure to flames than to worry about directing the force up?
My tank sits in a compartment w a lid without a latch. I won't be
adding a latch. But I wouldn't require latches be removed
either. Best prevention is to perform a leak test when you connect
the tank and soap joints.

NEVER lock or latch a propane locker! Repeat, NEVER. If the tank
explodes you want the force to blow upwards through the freely
opening hatch. If it is latched or locked, the force will blow
downward through the bottom of your boat. I don't think legal
propane lockers even have a latch. That is probably a code violation.

Jon,
If people used the same due dilligence with their gas engines that
you do with propane this would not be an issue.
I have all the propane equipment you do and still turn off the gas
at the tank when I'm done cooking. My propane locker has a pad lock
on it, rule on the boat is; Lock open, gas on, lock closed, gas
off. When I shut down the stove I step outside and shut the valve
at the tank and close the pad lock.
