Being trained in the use and knowing you have a clean air source are two biggies. I know when we blew dust from PC's at work you had to be conscious of DC charge build from prolonged use. For sensor cleaning you do not blow directly at the sensors. Think you essentially use the air wave to pull things away in its wake.
Air and water at increasing force within reason, alcohol/chemical treatments are the final resort as a general rule. Short of a medical supply I wouldn't trust compressed air to be particle free.
