thrombotic thrombocytopenic purpura. Description. Thrombotic thrombocytopenic purpura is a rare disorder that causes blood clots (thrombi) to form in small blood vessels throughout the body. These clots can cause serious medical problems if they block vessels and restrict blood flow to organs such as the brain, kidneys, and heart.
âTHE MOST IMPORTANT DRIVING TECHNIQUE TO AVOID CRASHES WHEN DRIVING IN ICY OR SNOWY CONDITIONS IS REDUCING SPEED AND INCREASING FOLLOWING DISTANCEâ. When you are driving on ice, you have to keep in mind that your wheels don't have as much traction as they do when you are driving on dry pavement.
Salt has always been applied to roadways since it lowers the freezing point of any water it comes into contact with. Traditionally, this was accomplished by applying solid rock salt before and after snowfall to reduce ice and snow. However, this strategy is only effective when temperatures are above 15 degrees Fahrenheit. These actions would be considered de-icing, which is removing snow and ice after the weather event has occurred.
