Before starting work, disconnect the power source, remove the ignition key or battery, and verify that the engine cannot restart. Apply a clearly visible lock and tag to the power switch or disconnect, documenting the servicing activity, date, and technician identity. When devices operate with stored energy, such as capacitors or springs, take additional steps to dissipate stored energy according to the manufacturer’s guidelines. Only authorized personnel should remove locks, restore power, or re-energize the equipment, and all steps should be logged to maintain traceability and accountability throughout the maintenance process.

Emission and environmental considerations must be addressed to minimize the ecological impact of lawn equipment maintenance. Proper handling and disposal of used oil, fuel, refrigerants, and solvents are essential to prevent soil and water contamination. Use approved containers for waste fluids and ensure they are properly labeled and stored in a designated containment area until disposal through licensed recycling or waste services. When performing tasks that generate exhaust or vapors, ensure adequate ventilation and consider using an exhaust capture method if available. Comply with local, state, and federal regulations regarding emissions controls, waste management, and chemical use to support a safe, compliant workspace and reduce environmental risk.

Appendix and references
