Significance and Use3.1 Carbon monoxide poisoning is responsible for approxi-mately 300 deaths annually in the U.S., (excluding fire deaths)and carbon monoxide poisoning causes thousands of individu-als to seek medical attention.

7、3.2 This practice is intended for use by individuals whoinvestigate incidents involving carbon monoxide poisoning. Ifthis procedure is followed, the cause for the carbon monoxidepoisoning incident may be determined, and steps can be takento prevent future incidents.4. Equipment4.1 Electronic Carbon

8、Monoxide MonitorA properly cali-brated direct reading electronic monitor having a range of 0 to1000 ppm is useful in that its output provides almost instanta-neous concentration data, and it therefore has the capability towarn the investigator if carbon monoxide levels are reachingdangerous concentr

9、ations.4.2 Reagent Tube IndicatorSeveral types of reagent tubeindicators are available for measuring carbon monoxide, car-bon dioxide, and fuel gases. Reagent tubes capable of respond-ing to concentrations of 0 to 100 ppm, 0 to 1000 ppm, and 0 to1 % carbon monoxide in air are recommended.4.3 Ventila

10、tion EquipmentA fan or similar device shouldbe available to allow flushing the air space around equipmentbetween tests.4.4 All equipment shall be calibrated at least annually.5. Safety5.1 Testing equipment suspected of causing carbon monox-ide poisoning can yield definitive results that cannot beobt

11、ained any other way. Testing equipment that may haveinjured individuals; however, is a potentially dangerous under-taking, in that the investigator runs the risk of becomingexposed to carbon monoxide being produced by improperlyfunctioning equipment.5.2 Safe testing procedures are of the utmost impo

12、rtance.Before any testing is planned, a safety officer shall be identi-fied. The safety officers responsibilities shall be to protect thesafety and health of the investigator and any individuals whomay be affected by the testing.5.3 Stable communications should be assured between thesite and emergen

13、cy service providers.5.4 Until its safe operation has been verified, only oneperson at a time should be allowed into any space where apiece of equipment is being tested for carbon monoxide output.That person should remain within sight of the safety officer oranother individual capable of rescuing th

14、at individual from thespace.1This practice is under the jurisdiction of ASTM Committee E30 on ForensicSciences and is the direct responsibility of Subcommittee E30.05 on Engineering.Current edition approved March 1, 2004.

16、, Boston, MA 02210.1Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, United States.5.5 All testing shall be discussed in detail with all individu-als involved in the testing, prior to the beginning of any test.6. Procedure6.1 Scene Securitythe first

17、 priority is to evacuate thescene and prevent further injuries or loss of life.6.1.1 After evacuation, the scene should be secured, and ifpossible, a field measurement of carbon monoxide levels invarious locations around the scene should be taken.6.1.2 The fuel supply to the scene should be turned o

18、ff. Thismay require the switching off of internal combustion engines,or the closing of valves for gaseous or liquid fuels.6.2 Documentary Informationcollect information relatedto the poisoning event, including emergency phone line record-ings, and medical records, particularly those that describe th

19、eblood gas analysis of the victims. Obtain statements as early asfeasible from all individuals associated with the incident.6.3 Identify all fuel-burning equipment in the site.6.3.1 A partial list of equipment that might be a potentialsource of carbon monoxide includes gas appliances (furnaces,range

20、s, ovens, water heaters, and clothes dryers), fireplaces,wood and coal stoves, space heaters, charcoal grills, campstoves, automobiles, gas-powered lawnmowers, and gas pow-ered tools.6.4 Once all of the fuel-burning equipment has been iden-tified, establish and document the condition of the valvesan

21、d/or switches on each piece of equipment at the time of theincident.6.5 Determine the source of fuel, air, and ventilation of eachpiece of equipment.6.5.1 Determine whether any of the equipment is located inan enclosure that can be defined as a “confined space.”6.5.1.1 Confined spaces are defined in

22、 NFPA 54 as, “a spacewhose volume is less than fifty cubic feet per 1000 btu per hour(4.8 m3per kW) of the aggregate input of all appliancesinstalled in that space.”6.5.2 Determine whether the equipment has an adequatesupply of air for combustion and ventilation as specified inNFPA 54, chapter 5.6.5

23、.3 Determine whether the equipment, if venting is re-quired, is vented to safely carry the products of combustionoutside, as required by NFPA 54, chapter 7.6.5.4 Determine whether any temporary obstructions of theequipment ventilation, including obstructions of the return airvents have been moved.6.

24、6 Planning the TestDevelop a plan for safely testing thepotential sources of carbon monoxide in the scene. In mostcases, this planning will involve preparation of a writtenprotocol for tests to be carried out. Refer to Practice E 678 inplanning any tests.6.6.1 This plan will typically include the tu

25、rning on ofequipment and observing its performance using the carbonmonoxide monitoring devices described in Section 5.6.6.2 Identify the individuals who will be conducting thetests, including the safety officer.6.6.3 Identify any individuals who may have an interest inthe outcome of the testing.6.6.

26、3.1 Such individuals may include the property owner,representatives of the victim(s), equipment manufacturers,equipment service personnel, law enforcement officers, codeenforcement officers, and the insurance carrier for any of theparties listed above.6.7 Notify individuals who have been identified

27、as possiblyhaving an interest in the testing of the time that the tests aregoing to take place. For additional guidance on notification, seePractice E 860.6.7.1 Keep a record of individuals who have been notified ofthe proposed testing.6.7.2 Notification of other interested parties may not benecessa

28、ry if the investigation is going to be limited to obser-vations that do not change the condition of any of the structuresor equipment.6.8 Operate each piece of equipment that has been identifiedas a potential source of carbon monoxide in the manner inwhich it is designed to be operated, and, using t

29、he equipmentdescribed in Section 5, measure the carbon monoxide output, ifany.6.8.1 Attempt to reconstruct temporary obstructions to thereturn air or combustion air vents or to the flues or chimneys.6.8.2 If abnormal operation of any piece of equipment issuspected, operate that equipment in the abno

30、rmal fashion, ifpossible, changing only one operating parameter at a time, andrecord the results.6.8.3 Operate equipment or appliances in combination, onlyif the combination of equipment is suspected of contributing tothe cause of the carbon monoxide buildup.7. Collection of Physical Evidence7.1 Onc

31、e all parties to the investigation are satisfied thatsufficient testing has been accomplished, items of physicalevidence pertinent to the conclusions may be secured.7.2 Label according to Practice E 1859.7.3 Frequently, the device that is identified as havingproduced the carbon monoxide can be resto

32、red to a safeoperating condition, and left in place after the condition thatled to the poisoning event has been sufficiently documented.8. Report8.1 The investigative report should include the followinginformation.8.1.1 Location, date and time of the incident.8.1.2 Extent of the victims injuries, in

33、cluding carboxyhe-moglobin (COHb) level in the victims blood.8.1.3 Identification of the source of the carbon monoxide.8.1.4 Identification of conditions that caused the source ofthe carbon monoxide to produce the carbon monoxide.8.1.5 Identification of a path of travel from the carbonmonoxide produ

34、cing device to the victim.8.1.6 A description of corrective actions needed to renderthe equipment safe.8.1.7 For additional guidance on reporting the incident,refer to Practice E 1020.E2292042ASTM International takes no position respecting the validity of any patent rights asserted in connection wit
