There is a degree of false equivalence here - while HM armed forces have certainly had their share of dockyard accidents and fires, the Russian safety record is of a different order of magnitude, especially their nuclear safety record for submarines when compared to that of the RN or USN.
Anyone remember the submarine reactor that was minutes away from a meltdown because the naval base hadn’t paid their electric bill and had the supply cut off disabling the reactor’s coolant system ? That was only resolved when the base commander sent an armed detachment of soldiers to politely ask if they would turn the power back on. Imagine that happening in Rosyth.
There still seems to be this mindset that the Russians are really “just like us” - when in fact they are nothing like us.
