10. Isolating electrical and pneumatic tools (Sample Toolbox Talk) Background Information (DO NOT READ): If you are done with an air tool, disconnect the hose at the source. This is type of isolation is a good practice. The danger of not doing this is if the air source were turned on inadvertently it could whip the hose around and could quite possibly cause an injury. The same applies to electrical tools. When you are done with a tool, disconnect it from the source of power. When changing grinding wheels for example, ensure that you have unplugged the grinder to isolate it. This will ensure that you don't inadvertently turn it on with your hand within close proximity to the disk. Talking Points: How do we isolate a pneumatic hand tool prior to making adjustments or changing parts? What other considerations should we take when dealing with air tools and hoses? How do we isolate an electrical hand tool prior to making adjustments or changing parts? When might you need to wear a face shield? TAKE THE TIME FOR SAFETY. REMEMBER NO JOB IS SO IMPORTANT THAT IT CANNOT BE DONE SAFELY.
