Batteries, Bulbs and Wires Batteries - Hooked up correctly - Make sure it’s working! - If damaged, throw away (battery acid) Bulbs - Again, make sure it works! - Handle carefully, it’s made of glass! - If broken, dispose in necessary glass containers Wires - Ensure each wire is completely insulated before touching! - Have wires going to intended objects - If you don’t know what it’s for, DON’T TOUCH IT!!!

When Dealing With Electricity… DO NOT!!!!! Put metal objects in outlets or when using appliances (ex: toaster) Take devices like radios into the bathroom or near the bath Walk where there are fallen power lines Climb transmission towers, trees or fly kites near power lines or exposed wires Pull out plugs by the cord Take apart electrical appliances (some contain capacitors which store electrical charge even if unplugged

Devices Invented To Prevent Shocks!!! Fuses Breakers Three-Prong Plug - “Grounds” your circuit so you don’t get a shock Grounding Wires – Electricity travels to the ground in case insulation fails

Create a Safety Poster! Use Illustrations and/or text that: Identify electrical dangers at work and play Identify electrical safety devices and procedures which protect us from these dangers.
