Identify three correct statements about the effects of weather and wind on spotting:
When operating during high wind conditions, spot the apparatus in a manner that requires the aerial device to me raised to the minimum extension needed
The primary spotting concern associated with hot weather is that extreme heat may tend to weaken firm paved surfaces
In sub-freezing temperatures, avoid parking the apparatus in a position where the raised aerial device will be subject to accidental contact with fire streams or overspray
Operating at a low angle of elevation and at a long extension is when aerial devices are at their weakest operational position. To minimize this effect, aerial apparatus D/O's should spot the apparatus:
As close to the intended target as safely as possible
As a D/O, if you must position your apparatus in an alley with dead end access, then you should:
Back to apparatus into the alley for a faster way out
True or false:
You should frequently check the stabilizers to ensure that they are in solid contact with the stabilizer pads and the ground at a highway incident.
True
