External Payload of Helicopter | Minimum Required Bucket Size |
780 | pounds and below | 50 | gallons |
781 | pounds - 1600 pounds | 100 | gallons |
1601 | pounds - 3900 pounds | 200 | gallons |
3901 | pounds and larger | 300 | gallons |
(c) A water source of sufficient capacity readily accessible to allow the bucket to be filled three times without refilling the source. The water source must be located within five minutes round-trip flying time of every part of the operation;
(d) The following sized fire tool kit packaged for ready attachment to the cargo hook and located at the heliport serving the operation:
(i) Two axes or pulaskis;
(ii) Three shovels;
(iii) Three adze eye hoes.
(e) Two fire extinguishers of at least 20 B C rating shall be kept with refueling equipment. They shall be appropriately mounted, suitably marked and available for immediate use.
(11) Railroad track installation and maintenance:
(a) Crews - ten people or less:
(i) A pump truck or pump trailer as defined in WAC
332-24-005(24); however the water capacity of the pump truck or pump trailer may be less than three hundred gallons, but greater than one hundred fifty gallons when the unit is capable of producing department-approved high expansion foam;
(ii) One serviceable five gallon backpack pump can;
(iii) Communications between the crew and dispatcher for reporting fires to the responsible protection agency.
(b) Crews - greater than ten people:
(i) A pump truck or pump trailer as defined in WAC
332-24-005(24) that is also capable of producing department-approved high expansion foam;
(ii) A fire tool box containing a minimum of:
(A) Six pulaskis;
(B) Six adze eye hoes;
(C) Six shovels.
(iii) Communications between the crew and dispatchers for reporting fires to the responsible protection agency.
(c) Track welding, cutting and grinding shall be curtained by not less than a four foot high canvas type curtain, which completely encloses the operation and prevents the escapement of sparks from welding, cutting or grinding.
(12) Prior to beginning operations, all snags, stubs and dead trees over fifteen feet in height shall be cut within fifty feet of each fixed-position machine which will operate for two consecutive days or more in one position.
The ground shall be initially cleared of all flammable debris under four inches in diameter beneath and within ten feet of each fixed-position machine which will operate for two consecutive days or more in one position.
(13) The area around the tail, corner and haul back blocks must be kept clean of all flammable debris under four inches in diameter for a distance of six feet in all directions. Suitable flame-resistant blanket devices may be substituted for the clearing requirement when the six foot diameter area is covered. Each block must be equipped with one serviceable five gallon backpack pump can filled with water, one shovel and one pulaski. Operations with multiple blocks must have this complement of tools and water within one hundred feet of each block.
(14) It shall be the operator's responsibility to identify points of line rub on cable logging operations during the closed season. If line rub occurs, the operator shall do what is necessary to stop, alleviate or control the line rub in order to prevent fires at these points. Satisfactory means include, but are not limited to:
(a) Removal of the object which the line is rubbing on;
(b) Changing the logging system;
(c) Moving the cable location.
(15) The department may designate certain areas which are known to have rapid fluctuations of extreme fire weather and/or concentrations of additional hazards. Operators in such areas may be required to monitor the humidity and/or wind speed and maintain a daily log of such readings. Relative humidity readings and wind speed must be determined and recorded by instruments and methods approved by the department.
The department may further require the operator in such areas to restrict operations when, in the opinion of the department, the recorded readings or current conditions are such that if a fire starts in that area it would probably spread to conflagration proportions regardless of personnel and equipment available for initial fire suppression.
