Safety concerns:

The oven should not be left unattended when the pieces of wood are left to dry in the oven for 24 hours. There is a possibility of the wood catching fire (although it is unlikely, if a proper temperature setting is used). Have fire safety equipment on standby. Be careful when removing the hot wooden blocks from the oven. Use gloves for protection.
