The price of the device has been steadily increasedâby 32 percent in the past year aloneâbut not because the cost of the raw materials was increasing (a typical dose of epinephrine still costs about a dollar). The profit margin of the EpiPen was 9 percent in 2008. Today itâs 55 percent.
Frost is a form of ice and can only survive at temperatures of 32 degrees Fahrenheit and below. But that doesnât mean the measured air temperature must be 32 or below for frost to form on a surface.
The chart below shows how long you can be exposed to certain temperatures before it will result in frost bite. For example, a temperature of 0Â°F and a wind speed of 15 mph creates a wind chill temperature of -19Â°F. Under these conditions frost bite can occur in just 30 minutes.
