  28. 44% of “forgotten” children were to have been dropped off childcare/preschool . 52% 29% 18%

  29. Average Age = 21 months

  30. More states have laws against leaving pets in vehicles Current Laws

  31. Child’s body less capable of cooling itself • A child’s body temperature rises 3 to 5 • times faster than an adult’s • Heat Stroke (i.e., Hyperthermia) • Cooling system is overwhelmed at 104 ° F • Symptoms • Stops perspiring, red dry skin, faintness, staggering, strong and rapid pulse; possible delirium or coma • Death at 107 ° F What is Heatstroke?

  32. Summer 2002 observational study • 16 study days • Outside air temperatures from 72 ° - 96° F • On two days, measurements were also made with the windows “cracked” 1.5 inches How Hot? How Fast?

  33. Incoming Shortwave Solar Radiation Warms Interior Objects How Do Cars Get Hot? Outgoing Longwave Radiation Heats the Air Air and Windows are Transparent to Sunlight

  34. How Hot? How Fast?

  35. How Hot? How Fast?

  43. Nearly half of temperature rise in 10 minutes • 80% in first 30 minutes • Temperatures plateau 45-50° above ambient • “Cracking” windows has minimal effect • Dark cars NOT necessarily worse than white cars • Published: Pediatrics, 2005 • Updated on the Internet Vehicle Heating Summary

  44. SAFETY RECOMMENDATIONS

  45. SAFETY RECOMMENDATIONS • NEVER LEAVE A CHILD UNATTENDED IN A VEHICLE.  NOT EVEN FOR A MINUTE! • IF YOU SEE A CHILD UNATTENDED IN A HOT VEHICLE CALL 9-1-1. • Be sure that all occupants leave the vehicle when unloading. • Teach your children that vehicles are never to be used as a play area. • Have a plan that your childcare provider will call you if your child does not show up for school.
