Free safety facts, no purchase needed: carbon monoxide, cold, heat and who to call
You do not need to buy anything to read this. It is the same guidance the book gives in Entries 35, 50 and 55 and Appendix C, from the agencies named.
Carbon monoxide. You cannot see or smell it, and a sleeping person can die before having any symptom (CDC). Never sleep with the engine running. Never use a fuel-burning heater, grill, camp stove, charcoal or generator where people sleep; a cracked window does not make it safe (CDC, CPSC). Keep a battery carbon monoxide alarm switched on and tested. Symptoms include headache, dizziness, weakness, upset stomach, vomiting, chest pain and confusion. If an alarm sounds or anyone has symptoms: get everyone out into fresh air first, then call 911, and do not go back in.
Cold. Hypothermia can happen even above 40 °F when you are chilled by rain, sweat or cold water (CDC). Warning signs in adults: shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech, drowsiness. In babies: bright red, cold skin and very low energy. Someone who was shivering and has gone quiet, sleepy and clumsy is getting worse. Call 911 right away (National Institute on Aging). Change out of wet clothes before you sleep.
Heat. Heat stroke is a medical emergency: a body temperature of 103 °F or higher, hot red skin that is dry or damp, a fast strong pulse, headache, dizziness, nausea, confusion or passing out. Call 911, move the person somewhere cooler, cool them with cool cloths, and give them nothing to drink (CDC). Never leave a child, a disabled person or a pet in a parked vehicle, even in winter (National Weather Service).
Who to call. 911 for danger to life now. 988, call or text, for a suicidal, mental health or substance use crisis, 24 hours a day. 211, call or text, or 211.org, for local shelter, safe parking, food, and warming or cooling centers. Poison Help: 1-800-222-1222. National Domestic Violence Hotline: 1-800-799-7233.
