ATV Drip Torch Introduction:  ATV Drip Torch Introduction The ATV drip torch firing device was developed to be mounted on an ATV and provides a method of igniting ground fuels, in a short time, on large acreages.:  The ATV drip torch firing device was developed to be mounted on an ATV and provides a method of igniting ground fuels, in a short time, on large acreages. The firing device uses the same standard mix used in hand-held drip torches.:  The firing device uses the same standard mix used in hand-held drip torches. The ATV Firing Operator (ATVF) can control the flow of drip torch fuel being applied to ground fuels from his/her driving position. The complete system is jettisonable by the ATVF in case of emergency.:  The ATV Firing Operator (ATVF) can control the flow of drip torch fuel being applied to ground fuels from his/her driving position. The complete system is jettisonable by the ATVF in case of emergency. ATV Drip Torch Operator (ATVF) Qualifications:  ATV Drip Torch Operator (ATVF) Qualifications Must be certified for ATV Driving and ATV Drip Torch operations. Must be a Firefighter Type 1 (FFT1) with previous RX Ignition experience. Must have had Fireline Safety Refresher Training for the current year. ATVF Training Requirements:  ATVF Training Requirements BLM ATV Basic and Advanced Training Documentation of ATV certification, as required by agency Familiar with operation of specific ATV drip torch unit (Operations Manual) Completion of BLM ATV Drip Torch Module and a minimum of one successful assignment Completion of the BLM ATV Drip Torch Operator Field Evaluation ATVF Currency Requirements:  ATVF Currency Requirements Performance in the position once within the last five (5) years. No other position assignments will maintain currency. Slide13:  PPE and Safety Equipment Job Hazards Analysis Components:  Job Hazards Analysis Components Header box All boxes in the header must be filled in. Basic Job Steps column Briefly describes various tasks in an ATV operation. Potential Hazards column Identifies potential hazard(s) when performing the task. Safe Job Procedures column Identifies safe job procedures to reduce or abate the hazard(s). ATV Drip Torch PPE :  ATV Drip Torch PPE 8-inch, lace-type work boots with non-slip (Vibram type), melt-resistant soles and heels Fire shelter Protective helmet (must be DOT approved). The standard wildland fire hardhat will not be worn while operating an ATV. (REDBOOK) some more thought needs to be done here regular driving versus fireline driving. Safety issue for not being able to hear. Goggles/safety glasses Hardhat ATV Drip Torch PPE (Continued):  Aramid shirt Aramid trouser Leather gloves FM Radio Additional PPE as identified by local conditions and Risk Assessment or JHA ATV Drip Torch PPE (Continued) Slide17:  Fire extinguisher not mounted on torch but easily accessible in event of a rollover, minimum size of 2A 10 B:C extinguisher Standard Individual Firefighter First Aid Kit Standard ATV Tool Kit Hand tool for shelter deployment or firefighting ATV Safety Items Slide18:  ATV drip torch tank will be empty prior to unloading or loading into pickup beds or trailers due to weight and balance issues. ATV Safety Items To be Considered Before Operations Safety Items . . . (Continued):  Whether a pickup or a trailer is used, the ATV must be securely tied down. Ratchet-type nylon straps are recommended. ATV brakes will be locked and the transmission should be in first gear or park during transportation. Safety Items . . . (Continued) Safety Items . . . (Continued):  The ATV Drip Torch will not be permanently affixed to the ATV. It will be mounted in a fashion that allows the operator to rapidly jettison the ATV drip torch during a malfunction. Safety Items . . . (Continued) Safety Items . . . (Continued):  Safety Items . . . (Continued) A completed JHA or Risk Assessment is required for operating an ATV drip torch. Supervisors and appropriate line managers must ensure that established JHA or Risk Assessment are reviewed and signed prior to any ATV Drip Torch Operation or at the beginning of the fire season. No smokejumper will operate the ATV Drip Torch because they only know how to fall from the sky. It is recommended that ATV drip torch ignition operations be performed with two ATV’s and operators, one ATV with drip torch and operator and a second ATV and operator for safety over site. Communications:  Communications The ATVF should have a direct communications link (portable radio) with the Ignition Specialist and/or Burn Boss. Helmet headsets attached to radios are ideal; however, the best alternative is a radio carried in a chest pack. The chest pack makes the radio more audible than when carried on a belt at the waist. ATV Firing Organization:  ATV Firing Organization Prescribed/Wildland fire positions that the ATVF may work for include: Prescribed Burn Boss (RXB1 or 2) Ignition Specialist (RXI1 or 2) Firing Boss (FIRB) The ATVF works directly for these positions. ATVF Duties and Responsibilities :  ATVF Duties and Responsibilities Perform a pre-burn inspection of ATV and torch – using checklists. Correctly install torch and safety equipment on ATV.
