Girl Scouts version is Safety-Wise
Need a "leader experienced in cold weather camping ... with strong common sense." Know everyone's capabiltiies and set limits. Do a gear shakedown.
Extra batteries, cold specific stuff. li-ion batteries perform best in the cold. Hi vis clothing.
Participants need to be fit. Take rests, prevent overheating!
snowshoeing is "no more than 5 mi/day" lol?
buddy system: monitor for hypothermia, etc.
Use a winter camping checklist and trip plan
Lakes are safer than rivers (moving water)
Not just snow, but also tornados and hurricanes (Buffalo, NY is a "low risk zone": 8 recorded since 1930)
Leaders need to have taken Hazardous Weather Training
Check the National Weather Service forecast, have a Go/No Go decision
Understand warning vs watch vs advisory, wind chill
No flames in tents, even hot tents
Review everything before leaving for camp.
