<br /> <br /> <br />and hauling crews will have received a copy of the scope of work, accident prevention plan, safety indoctrination, <br />and assigned a crew foreman. All crews and foremen will be instructed by the Load and Haul Supervisor that they <br />are to work in areas designated by a Government Debris Manager and are not to relocate or move from one area <br />to another without prior approval. No employees or subcontractors of TFR will be allowed to work for private or <br />other public entities while employed or contracted under this project. <br /> <br />Hazardous Tree Removal <br />Unstable and leaning trees along a public ROW or within a naturalized area, such as public parks or golf courses, <br />are eligible for removal. The Sub-Grantee may choose to attempt to save the tree through straightening and <br />bracing if the cost of repair is less than the removal and disposal. A tree is deemed hazardous and eligible for <br />removal if: <br /> The tree is an immediate threat to public health and safety or improved property <br /> It has a DBH of 6” or greater <br /> AND one or more of these criteria: <br />- 50% or more of the crown is damaged or destroyed <br />- A split trunk or broken branches that expose the heartwood <br />- Fallen or uprooted within a public use area <br />- Leaning at an angle greater than 30 degrees <br />After a tree has been deemed eligible and scheduled for removal, TFR tree crews will discuss a tree-specific <br />removal plan to ensure a safe, proper felling operation, considering: <br /> Surrounding area for anything that may cause trouble when the tree falls <br /> The shape of the tree, the lean of the tree, and decayed or weak spots <br /> Wind force and direction <br /> Location of other people <br /> Electrical hazards <br /> <br />Once the tree crew has identified a tree-specific removal plan, the following procedures shall take place: <br />1. The employee shall work from the uphill side whenever possible. <br />2. Before felling operations, the work area shall be cleared to permit safe working conditions and an escape <br />route shall be planned. <br />3. Each worker shall be instructed as to exactly what he/she is to do. All workers not directly involved in <br />the operation shall be kept clear of the work area. <br />4. Before starting to cut, the operator shall be sure of his/her footing and must clear away brush, fallen trees, <br />and other materials that might interfere with cutting operations. <br />5. A notch and back cut shall be used in felling trees over 5 inches in diameter measured at breast height <br />(DBH). No tree shall be felled by “slicing” or “ripping” cuts. <br />6. The depth of penetration of the notch shall be about one-third the diameter of the tree. The opening or <br />height of the notch shall be about 2.5 inches for each 1 ft. of the tree’s diameter. The back cut shall be <br />made higher (approximately 2 inches) than the base of the notch to prevent kickback. <br />7. The resulting notch shall be flush cut to the ground. <br /> <br />Hazardous Limb Removal <br />Hazardous limb removal work shall consist of the removal and disposal of storm-damaged limbs that are: <br /> Imminent and impending peril to the general public <br /> Greater than 2” in diameter at the point of breakage <br /> Broken and still attached to the tree <br /> <br />The resulting debris will be collected from the grounds and hauled by normal debris collection standards. <br />ITB No. 23-04-01 <br />Disaster Debris Management and Disposal Services <br />87
