Refer to JHA for walking, hiking and foot travel Refer to JHA for plant, animal and insects Refer to JHA for hand tool use Proper PPE includes: hardhat, gloves, long pants, long shirt, 8" high leather boots with lug soles or calked boots, radio, pile jacket, compass and rain gear. Refer to JHA for communication A crosscut class approved by the Forest C-Certifier. Basic ppe, communications and LCES as it pertains to saw use. Must have first aid every 3 years and cpr every year. Must demonstrate sawing ability in functional areas. Sawers must learn the obligation of saying "NO" and walking away from any situation. Manage fatigue and hydration. Safe use of common hand tools. Must be able to deal with environmental extremes. A, B and C Trainee sawyers will be under the supervision of a certified C sawyer or a C-Certifier, until they have demonstrated the ability to handle the saw independantly and proficiently. A and B sawyers must be certified by a certified C sawyer. C sawyers must be certified by a C-Certifier. C-Certifiers must be certified by the Regional Saw Coordinator. Certification expires 3 years from the date of issue. Instructors have complete authority to limit the scope of the certification and can impose restrictions such as specific project, specific funtion, size limitations and species. Designated district saw instructors will work with the Forest Saw Coordinator pertaining to the certification process. The district saw instructors will work with the Forest Saw Coordinator to keep this data base updated. Eye protection, gloves, long sleeved shirts, hard hats, 8" high minimum leather boots w/ lug soles, optional for crosscut and first aid kit, (big enough to serve the amount of people on the project). General saw use: Equipment Crosscut saw Must have a proper covering sheath for all the cutting teeth. Must be sheathed when not in use. A crosscut saw must be at least three feet longer than the diameter of the tree or trees being cut. Must have good working handles, kerosene, wd-40 (or relevant lubricant) and appropriate files for the type of crosscut saw being used. Teeth must be sharp. All saws Must have wedges big enough for the tree or trees being cut. Single bit axe, with sheath, (3-5 lbs.) If a double bit axe is to be used, the sawyer must have a maul or single bit axe to drive wedges. Cross Cut Sawyer JHA - Page 1 of 5

2 Transport of saws Crosscut - walking Carry saw so teeth point away from body. Carry saw on the downhill side. Crosscut saw must have an appropriate sheath covering ALL the cutting teeth. When carrying the crosscut saw unsheathed, grip the back of the saw firmly with both hands. Keep the cutters pointed away from one's body and be cautious! All saws on packstock Saws must be properly sheathed. The crosscut saw should be bent in a horseshoe shape and adequately secured. Crosscut saws in a vehicle Saws must be properly sheathed. Do not transport the saws in the passenger compartment along with people. Do not lay other equipment on the crosscut saw. Saw must be secured in a way to keep it from coming unbound. Crosscut saw in aircraft Saws must be properly sheathed. Saws will not be transported in the same compartment with people. Saws will be properly secured to prevent movement. Saws will be adequately secured to some object as to prevent them from falling through a cargo net. Crosscut saw will be bound in a way to prevent opening. Proceedures: general Spacing Space employees so the activities of one will not create a hazard for another. Dangerous trees will generally be marked, and people will stay clear by 2 1/2 tree lengths. People not essential for the mission will keep outside the 2 1/2 tree length safety circle. Ensure adequate traffic control measures are taken on roads, trails and firelines. Have workers and felling crews working on the same contour rather than some working above others on steep hillsides. Leap frogging Communications Escape routes Weather / Darkness Overhead hazards Footing Cutting area control by the felling boss or saw operator is imperative. Must have a documented tailgate safety meeting to set forth proceedures for this method of saw team deployment. Must have established means of communcation, ie. yelling, radio, hand signals, etc. Communications must be clear, concise and understood by everyone involved. Refer to JHA for communications All bucking, limbing and felling operations require clean escape routes with a minimum 20 foot path before starting to cut. Escape routes are predetermined paths along which the sawyer proceeds once the tree is committed to fall or to the bucking cut. Choose an escape path that extends diagonally away from the expected felling line and always have an alternate retreat path to a safety zone. Do not saw during high winds, lightening/thunderstorms or other hazardous weather. Do not conduct felling operations if the tops or the 2 1/2 tree length safety circle is obscured by darkness, smoke, fog or any other condition. One must have secure footing to conduct any type of saw operation. Whether thinning, bucking, limbing or falling look up and around often without compromising your cutting activity. Watch for brushing of other obstacles. Ensure firm stable footing all the time. Bind Anticipate log tensions and compressions and plan mitigation. Use wedges and / or a pie cut or other types of bucking cuts as preventative measures. Continually observe the kerf. Cross Cut Sawyer JHA - Page 2 of 5

3 Proceedures general (continued) Proceedures: felling Bucking / Rolling logs Tension Size up Human factors Preparation Felling Always Use caution when cutting limbs supporting logs off the ground. Do not saw from downhill side. On steep ground prevent bucked sections from rolling or sliding. Do not buck logs on steep slopes with people below. Be aware of one's surroundings. Must have a good escape route. Watch for and carefully relieve tension on saplings and limbs with a series of small cuts to tensioned side. Must have a good escape route. Plan for where the tree or limb will end up after it is cut. Watch for brushing of other obstacles. Consider lean, limb distribution, wind, soundness of tree (rot, root problems, split, broken or burning top, lightning struck, loose bark), species (live or dead), topography, steepness of slope, obstructions (people, trees/snags, structures, powerlines, roads, travel in the cutting area, moisture in the form of rain, snow or ice), widowmakers, spiked/schoolmarm, burning, diameter, height, escape routes (primary and secondary), and safety zones. Wind direction and velocity such as steady versus gusting and / or changing directions. Consider one's physical capabilities of doing the job one is asked to do. Does one have the experience to do the job one is asked to do. While testing keep side conversations/noise to a minimum. After size up, clear escape routes and work area. Walk out and clear the intended lay. Bore the tree if necessary to determine soundess. With crosscut determine who handles the saw as tree falls. Identify the swamper and have communications understood. Saw from a safe standing height with eyes up. The undercut must be clean, no dutchman, and with an opening large enough to control the tree nearly to the ground. All trees over 5" dbh must be undercut before making backcut. Do not use corner or side cuts in hollow or heart rot trees, unless adequate holding / hinge wood can be maintained. Preposition wedges and felling axe before starting backcut. Give a shout before beginning backcut. Insert the wedges into the backcut as soon as possible. Give a shout as the kerf starts to open. In small diameter trees wedge into a corner cut or use rifled wedges. Do not cut off holding wood. As tree commits to the undercut, watch the top as one gets quickly away from the stump. A minimum of 20 feet. If the tree compromises the primary safety route, use the alternate. Watch for falling tops and limbs for at least 30 seconds. Do not leave a partially cut tree without marking the safety circle of 2 1/2 tree lengths and warning others. When using a chainsaw or crosscut saw and the situation is deemed unsafe, alternate methods shall be used, or the task cancelled. There is no shame in saying no. Cross Cut Sawyer JHA - Page 3 of 5
