Narrative:
In climb out; my captain was lowering his sun visor in anticipation of climbing through clouds and mistakenly turned off our inertial reference 1 (IR1) just like what was described in [a recent company] newsletter. QRH procedures were followed; and we arrested the climb and requested FL280 as final to avoid rvsm airspace. Options were discussed using great CRM and dispatch was informed. We were flying to [a destination] where the weather was VFR and we kept a constant plan in case of emergency descent since we lost egpws. This is mostly an informational report since it is a known problem so that these incidents can be tracked and a fix may be found to this known risk.
