  1. March 2010Safety Meeting Lt Col Larry Brockshus

  2. Overview • Safety on lake and river ice • Texting and driving • Aircraft icing • February mishap • No March Sentinel as of 1 March

  3. Ice Safe • There are several sports you can enjoy on the ice • Ice Skating • Cross county skiing • Ice fishing • Snowmobiling • Hunting • Falling through ice is a real hazard

  4. Danger: Thin Ice!! • Ice thickness is difficult to judge • Can vary from thick to dangerously thin in a few feet • Ice around submerged items • Ice under snow • Ice over moving water • Thick ice can be weak • Ice that has frozen and thawed repeatedly • After a sudden extreme cold

  5. Read the Signs • Signs of Thin ice • Slushy areas • Dark areas • White or cloudy • Strongest ice • Clear with a blue tint • At least four inches thick

  6. Use the buddy system • Don’t go out alone • Walk on different areas about 10 feet apart • Avoid night time • Let someone know when you will be back and where you are going

  7. Pack it up • Carry a survival kit • Lighter or waterproof matches • Fire starter • Pocket knife • Compass • Ice picks or spikes • Rope • Cell phone in water proof bag (broadcast GPS) • Consider life jacket or floater suit • Carry a 10 ft pole or 2x4 when Ice fishing

  8. After the Plunge • Take off snow mobile helmet • Keep head above water (swimming skills do not help much) • Have friend call 911 • Turn toward the direction you came from • Put hands or Ice picks on unbroken surface and pull top of body onto the ice • Kick feet and work body out of the water • Let water drain off • Stay flat, crawl/roll back to strong ice • Fight hypothermia

  9. How to help • Call 911 • Reassure the victim • Don’t go near the edge • From a safe location, extend an object to help pull them out • If pulled toward the hole, let go and start over

  10. How to help with hypothermia • Call 911 • Remove person from the cold • Remove wet clothing • Keep victim dry • Wrap victim in blankets/sleeping bag • Build a fire to warm victim • Give warm fluids (no alcohol) • Seat victim in warm shower or bath

  11. Symptoms of Hypothermia • Absentmindedness or confusion • Lack of coordination and weakness • Difficulty speaking • Semi-conscious or unconscious • Uncontrolled shivering

  12. How thin is safe • 4 inches - person • 6 inches – snow mobile • 8-12 inches – car • 12 -15 inches – large pickup

  13. Home Made Ice Picks • Two 4 inch wooden dowels (material that will float) • Drive stout nail into one end of dowel • Sharpen the nail • Drill hole into opposite end for a cord to connect claws • (Consider drilling a hole along side the nail so the nail can point of the other pick can nest in the hole to keep the points covered)

  14. Texting While Driving OMG! Think I’m bout 2 die!

  15. TextingA message to die for: • Common factor: all operators were texting • 17 year old driver swerves into oncoming traffic and hit truck head on, killing herself and four passengers • California train engineer involved in collision that killed 25 and hurt 130 • 27 year old man crashes into another car killing the other car’s driver, driver charged with negligent homicide

  16. Texting facts • Driver inattention is involved in 80% of crashes • 46% of teenagers text while driving • Drivers using their cell phone are: • 18% slower to brake for a hazard • Impaired on par with a driver with an alcohol level of .08- above the legal limit

  17. Aircraft Icing 101 • Why the concern?? • Disrupt air flow affecting lift and drag • Reduce lift by 30% • Increase drag by 40% • Increase stall speed • Adds weight and balance problems • Decreases fuel efficiency • Decrease control • Can cause vibration • Interfere with gear, brakes, radio signals • Bad instrument readings • Visibility

  18. Structural • Clear Icing • Probably the most hazardous • Clear and Shinny • Heavy and difficult to remove • Liquid water hits, then spreads out on a freezing surface (below -20 degrees C water will be crystals not droplets) • Rime • Grainy and opaque, rough texture • Small drops hit the aircraft • Lighter than clear ice • Frost • Thin layer of ice crystals

  19. Test from NASA Glenn Research Center • Exposure to clear ice for two minutes • Double drag • Reduce lift by 25-30 percent • Reduce critical angle of attack 8 degrees

  20. January Incident • Member found paint missing on wing tip after it may rubbed along the top of another wing while being pushed out of the hanger. No structural damage found.

  21. Stay safe • Why attention to detail and check list discipline is important. • Caution: Do not put scissors into mouth.
