Removing a breaker

I have several Eaton Magnum DS breakers that I am removing. They are spare breakers and are already in the disconnect position. Would it be safe to remove the breakers while not wearing an arc flash suit? They are already disconnected from the bus and I don't see an arc flash hazard present to do so.
Please share your thoughts along with any supporting recommendations from manufacturers on this.
 
Go to Table 130.5(C) in NFPA 70E, Estimate of Likelihood of Occurrence of an Arc-Flash Incident, and you'll see the task you're doing and that there is a chance of an arc-flash incident, regardless of the condition, so I would be suited to the incident energy level that's available.

....unless it's arc-resistant switchgear!

NO.

Arc flash, and other, PPE is always required when working on or near exposed energized conductors.

The NEC is about installations.
Groups like OSHA and insurance company policies usually refer to NFPA 70E.
