Is it hazardous to operate the Emerson MW8626W 600 Watts Microwave Oven without anything in it? Either to the oven or to the operator? If so, what is a recommended load to prevent accidental damage or hazard?

Re: Operating a microwave oven without a load
In principle no it is not hazardous.
In practice however, unless the machine is clean to the point of sterile, small items in the microwave can absorb more energy than they would if a large item was in the machine also. This can produce some damage to the machine.
manufacturers generally recommend not running microwaves empty.
Why would you want to?
If in doubt, just a cup of water would be more than adequate.
it is not a good idea to modify a microwave oven in any way.
Hope this helps :)

Take a look at the oven's electric rating information. It should be on the label with the model and serial number, and it will tell you how many amps the oven needs. Power in watts is volts times amps, so a 1000-watt inverter is good for about 8 amps at 120 volts output. Some inverters also use a peak rating, meaning power than can be delivered for a short time. The continuous power may be less than that; you'll need to look at the inverter. As long as the power needed by the oven is within the inverter's ratings then you'll be able to use it. Otherwise you'll need to shop for one with more output power.
There are two or three switches operated by the door latches in a microwave oven. When the door is slammed, they can be damaged or knocked out of adjustment. If the control board thinks the door is open, it won't allow the oven to operate. It's best to let a professional check the oven and adjust or replace the affected parts. Microwaves are hazardous devices, with lethal voltages exposed when the cover is off. Also, repairs involving door repairs can cause microwave leakage if they aren't done properly. But once the switches are operating properly your oven should be fine.
Look at the rating sticker on the oven and use the AC power rating as your guide. The cooking power of the oven is not important, but the power it needs from the AC supply is. Voltage times current is the supply power needed (watts), and you want an oven that will draw less than the inverter's continuous rating, less any power being used by other appliances.
For instance, a microwave rated for 120 volts AC at 10 amps needs 1200 watts. Your inverter would be OK with this as long as other devices aren't using more than another 1000 watts. You can't use the inverter's peak rating. That's only for brief bursts, like when the microwave first kicks on and draws some extra current.
Any mid-power (600 watts or so) oven should be OK.
