I'm afraid that is like asking, "Does a car have a tape player?" It depends on the make and model. Personally, I have a Colt .22 Model 3 derringer and it does NOT have a safety. But, I cannot speak to the many other makes and models.
To load a .22 caliber short derringer, first ensure the firearm is pointed in a safe direction and the safety is engaged. Open the barrel hinge to expose the chambers. Insert a .22 short cartridge into each chamber, ensuring they are seated properly. Once loaded, close the barrel securely, disengage the safety, and the derringer is ready to fire.
The maker of your Derringer is no longer in business. Sorry-
