Be informed: make sure you know the rules and access conditions, be courteous to site owners and managers. Follow the signs for parking and avoid sensitive areas.
Limit crowds: climb in small groups to limit the impact on the environment and overcrowding on the routes.
Share the ice: be aware of other climbers around you while keeping a safe distance. Communicate courteously and share the space equitably.
Warn in case of danger: inform your rope partners or any other climber if pieces of ice fall.
Have a way to communicate: Make sure you can communicate with your group. A person remaining at base camp should be able to communicate with each of the climbers during the ascent. Use the guardian angel principle by making sure someone knows your exit plan.
