It looks OK, it doesn't get used much, why should I spend my money?
The below incidents tells it all, All pressurised cylinders are dangerous!
During an inspection of a Company's vessels, the Surveyor showed the attached pictures which were taken after an incident took place on another Company's vessel (he didn't disclose name of the Company or the vessel's name).
As you can see, it occurred due to a gas bottle exploding in a lifeboat during the process of charging it up from the Breathing Apparatus Air Compressor.
The Master of the vessel was in proximity of the lifeboat and he was very seriously wounded. The vessel was 8 years old. The bottle was quite old with different numbers/dates.
