1、Designation: F 2230 02Standard Guide forIn-situ Burning of Oil Spills on Water: Ice Conditions1This standard is issued under the fixed designation F 2230; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A

2、 number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide addresses in-situ burning as a response toolfor oil spills occurring on waters with ice present.1.2 There are several meth

3、ods of control or cleanup ofspilled oil. In-situ burning, mechanical recovery, dispersantapplication or natural recovery are the usual options available.1.3 The purpose of this guide is to provide the user withgeneral information on in-situ burning in ice conditions as ameans of controlling and remo

4、ving spilled oil. It is intended asa reference to plan an in-situ burn of spilled oil.1.4 This guide outlines procedures and describes someequipment that can be used to accomplish an in-situ burn in iceconditions. The guide includes a description of typical icesituations where in-situ burning of oil

5、 has been found to beeffective.1.5 In making in-situ burn decisions, appropriate govern-ment authorities should be consulted as required by law.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standa

6、rd to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use. Specific precau-tionary information is given in Section 8.

Significance and Use4.1 This guide is meant to aid local and regional spillresponse teams

12、 during spill response planning and spill events.5. General Considerations for Making In-situ BurnDecisions5.1 For marine spills of oil in ice conditions, in-situ burningshould be given equal consideration with other spill counter-measures and may be the best available technology for iceconditions.5

13、.2 The decision of whether or not to use in-situ burning ina given spill situation is always one involving trade-offs, thatis, smoke plume and residue.5.3 One of the limitations of recovery techniques for float-ing oil is effective containment of the slick. In-situ burning issubject to this constrai

14、nt as a minimum thickness of about 2mm is required for ignition and sustained burning of the slick.1This guide is under the jurisdiction of ASTM Committee F20 on HazardousSubstances and Oil Spill Response and is the direct responsibility of SubcommitteeF20.15 on In-Situ Burning.Current edition appro

16、ternational, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, United States.Natural containment of spilled oil can occur in some iceconditions. The presence of ice can inhibit the spreading andweathering of the oil slick. At higher ice concentrations, oilwill spread more slowly

17、than it would in open water. When iceconcentrations are lower, spreading can still be reduced by theeffect of wind herding. Oil herded by wind can concentrateagainst ice floes and can accumulate to thicknesses capable ofsupporting combustion.5.4 In this guide, environments suitable for in-situ burni

18、ngwill be discussed. The matrix in Table 1 is provided to assistusers of this guide.6. Marine Environments6.1 For the purpose of this guide, in-situ burning in iceconditions refers to marine coastal waters, rivers and lakeswhere oil spills may occur in ice infested waters.7. Background7.1 In-situ bu

19、rning protects the marine environment fromthe effects of an oil spill by consuming the oil by fire leavingas little as 1 to 10 % oil residue on the surface of the water. Byremoving the oil from the water and ice, the impacts on thesurface and sub-surface biota are reduced. Oil released bymelting ice

20、 may ultimately impact shorelines, including criticalhabitats such as marshes and bird rookeries. Oil floating on thesurface has the potential to contact marine life. Stranding of oilin these environments may result in adverse impacts fromcontact with oil. Fresh oil burns most efficiently. The amoun

21、t ofoil spilled, the degree of ice cover and weather conditions arefactors that determine the impact of a spill and the burnabilityof the oil.7.2 In-situ burning of an oil spill requires an ignition sourcewith the ability to provide multiple ignitions. The helicoptersling-mounted drum filled with ge

22、lled gasoline or dieseldeveloped for lighting backfires during forest fire fighting, is aneffective system for igniting oil in ice conditions. Individualigniters dropped from aircraft may be used to ignite oilcontained by ice. Since burning is most efficient when the oilis relatively fresh and unemu

23、lsified, sources of ignition shouldbe identified by response planners in their pre-spill contingencyplanning.8. Recommendations8.1 Use of helicopter-mounted ignition systems or indi-vidual igniters is a hazardous operation and all applicablesafety instructions for their use should be followed. Hazar

24、dousmaterials may have to be handled as part of the ignitionequipment. Appropriate MSDS sheets should be available andfollowed during use of this equipment.8.2 The in-situ burning of spilled oil can be accomplishedunder certain conditions:8.2.1 When oil is contained in close pack ice conditions(pack

25、 ice of 7/10 coverage or greater).8.2.2 When oil contained in drift ice conditions is sufficientthickness to sustain a burn (drift ice of 2/10 to 6/10).8.2.3 When oil is contained in fire-resistant boom (generallyopen water up to 1/10 ice coverage).8.2.4 When oil is trapped along an ice floe or herd

26、ed bywind and has sufficient thickness to support a burn.8.2.5 When oil is contained in melt pools on top of icesheets.8.2.6 When oil is contained in open fractures or leads in ice.8.2.7 When oil is flowing under ice in a stream and ice canbe slotted to bring oil to surface to burn.8.2.8 When oil is

27、 spilled on surface of ice and has sufficientthickness to support a burn.8.3 In-situ burning of oil may require certain regulatoryapprovals.8.4 Although in-situ burns are efficient, there always willremain some residue and provisions for the recovery of thatresidue should be included in in-situ burn
