- Use Designated Ice Surfaces4: Many towns designate skating areas in city parks and trained personnel regularly check the ice, to reduce risk of accidents. You should still evaluate conditions before heading onto the ice as ice conditions vary from day to day and throughout the day and always heed “Thin Ice” / “Stay Off The Ice” warnings, if applicable.
- CHECK THE ICE – Wear a lifejacket while testing & keep a buddy nearby
- Ice color: Clear, blue, or green ice is the strongest. Stay off of brown or white ice – white ice has snow in it and is weak5; brown, spring ice is also weak even if it measures the right thickness.
- Ice thickness: Stay off of ice less than 4 inches thick!6 Thickness can vary over a water body, so check the ice in several spots before allowing others onto it. To accurately check, you must bore into the ice with an ice auger, ice chisel, or drill, then measure with a tape measure. For people up to 200 pounds, the minimum recommended ice thickness is 4 inches. Snowmobiles or ATVs require the ice to be at least 5 inches thick7.
- Ice Quality: Stay off the ice if it is thin, broken, cracked, or discolored (white or brown). Where fatalities occurred, “the most common ice condition was thin ice at 57%, followed by an open hole in the ice at 21%, cracked ice 8%, and ice floe 8%.”8
- Type of Water Body: NEVER GO ON ICE OVER MOVING WATER! Do not travel on ice on rivers, reservoirs, or lake inflow/outflows! “Reservoirs accounted for 19% of all ice drowning.”9
- Weather Conditions: Rapid cooling is just as dangerous as rapid warming. Rapid warming can cause melting, while rapid cooling can cause ice to crack10. Ice strength can change throughout the day, so always test the ice before allowing others onto it!
- Select shallow water. Staying near shore on ice over shallow water greatly reduces the risk of severe injury or death.
- Supervise children and keep them within arm’s reach: “None of the toddlers and only 10% of 5-14 year olds who drowned during activities on ice were accompanied by an adult.”11
- Go With a Friend: Most adults who died falling through ice were alone.12
- Stick to Daylight Hours: “Nearly all snowmobile drownings occurred late in the day or at night.”13 No matter what activity you are pursuing, better visibility allows for a better inspection of the ice, helps you keep tabs on members of your group, and will aid in rescue attempts if necessary.
- Stay Alert (& Stay Sober): “Alcohol was associated with at least 59% of snowmobile drownings.”14 When our judgement is impaired, we may take risks we ordinarily wouldn’t and endanger others who will come to our aid.
- Wear a PFD Over Your Coat15: It might look funny, but could save your life!
- Carry Ice Rescue Devices16: Not everyone has an ice pick or ice axe, but at the very least, a rope with a loop tied on the end could come in handy in the event you need to rescue someone. A flotation ring is also helpful if the victim is not wearing a lifejacket. Hiking poles may help if the victim is alert enough to hold on – in very cold water, hypothermia can set in rapidly.
- Take the same precautions whether you are in an urban or rural area: 36% of deaths occurred in urban areas17. It is easy to get a sense of false security in town, but ice conditions change constantly, so you need to pay attention.
- Know What to Do If You Fall Through the Ice: Try to stay calm, keep your head out of the water, kick to get yourself up onto solid ice closest to land, then stay low. Shout for help and try to pull as much of yourself onto the ice as you can. Crawl or roll away from the broken ice18.
