Our company limits are good for keeping us out of trouble, no rotor start/stop at 45kts clean air or 35kts if gusty (max 10kts so 25G35kts).
That said when it gets closer to that having someone hold the blade on start its good for some reassurance. I haven't had to push the wind limits much out here but heard many stories from the guys out of Goose Bay having to turn around since they couldn't shut down on the pad due to winds. Even landing can be hard on some of the cliff sites, once they tried but have full collective down and were still climbing!
My worst wind story was actually in an R44. Doing a news patrol and saw a shimmer coming in from the west. Was a microburst kinda event, not sure what to really call it since it lasted longer and was basically a wave of high winds crashing out of the mountains. Shimmer was all the dust it was picking up on the way. Anyway managed to beat mostly it to the airport and touched down with winds of 53G58kts. Not really good time to shut down but also end of the shift so machine was on fumes and would be shutting off on it's own soon enough. Blades were sailing for a good 30min since the winds took a while to go back to normal (last report before I shut the radio off was 55G62). The R44 has these little plastic(?) cushion block things for mast bump stops, both of them were firmly indented but no actual damage done. Closest I've ever come to knocking off my own tail boom, probably just pure luck and the fact the gust spread never went over 10kts!
As far as drums go we don't use them on the NWS unless something bad happened to the fuel. The sites all run on Jet A so same fuel for the generators goes right into the helicopter if we need it. Did have to use some drums in the summer because a couple beach tanks had fuel unapproved for aviation use due to issues with the FSII not being up to spec. Silly cause we don't really need it with out oil-fuel heat exchanger.
