Performance Objective Students will be able to describe the safety applications involved in working with small engines

Enabling Objectives – Explain the importance of a well organized work area – Describe the handling of flammable material – Explain proper work ethic of small engines

Lawnmower Accidents 9 percent of these accidents were caused by mechanical failure 91 percent of these accidents were caused by human error

Protecting your health Keep your feet, hands, hair and clothing away from moving parts of equipment Always use eye protection Wear hearing protection Wear specially designed gloves Wear safety shoes Use proper lifting techniques

Lawnmower Maintenance Safety Work Space Environment Correct tools for the job Keep an approved fire extinguisher in a familiar location Learn engine shutoff procedures Disengage cutting blade Disconnect the spark plug wire Disconnect the negative battery cable Avoid contact with hot engine parts Never strike the flywheel with a hammer Make sure all guards are in place Remove any fuel and oil from the engine Keep engine speed settings within manufactures specification

Gasoline Safety Be aware that fuel vapors may be present Allow the engine to cool before refueling Replace leaky fuel lines or fittings Keep gasoline, solvent and other flammable materials in an approved storage cabinet Never smoke while using, servicing or refueling a small engine

Small Engine Certification Did you know that a certified small engine mechanic $30.00 an hour! All it takes is a couple of tests and that could be you!

Clean & Organized Work Place A well organized work area includes: Clean floor and table Hazardous material stored properly Tools and supplies are easily located All tools are in good working order Within reasonable reach Correct tools for the job

Flammable Materials Gasoline –Is easily ignited –Should never be used for cleaning –Stored in well ventilated area, spark free area

Flammable Materials Small engine Batteries –Contain Hydrogen and sulfuric gases –Should be kept away from sparks –Handle with care

Flammable Materials Oil solvent waste –Anything saturated with petroleum –Stored in proper ventilated, spark free container

Small Engine Work Ethic Lift heavy objects with knees, not back Always pull wrenches etc; toward your body Have proper ventilation when working and operating small engines because of CO levels Acquire help if needed and use common sense

Key Points Organization of small engine work area Importance of handling of flammable material Safe work progress with small engines
