Significance and Use3.1 Carbon monoxide poisoning is responsible for approxi-mately 300 deaths annually in the United States, (excluding firedeaths) and carbon monoxide poisoning causes thousands ofindividuals to seek medica
8、l attention.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 Electr
9、onic Carbon 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 reachingdanger
10、ous concentrations.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
11、.4.3 Ventilation 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
12、cannot beobtained any other way. Testing equipment that may haveinjured individuals; however, is a potentially dangerousundertaking, 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 u
13、tmost importance.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.1This practice is under the jurisdiction of ASTM Committee E5

17、n 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 that individual from thespace.5.5 All testing shall be discussed in detail with all
18、individu-als involved in the testing, prior to the beginning of any test.6. Procedure6.1 Scene SecurityThe first 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 l
19、evels invarious locations around the scene should be taken.6.1.2 The fuel supply to the scene should be turned off. 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 poiso
20、ning event, including emergency phone linerecordings, and medical records, particularly those that de-scribe the blood gas analysis of the victims. Obtain statementsas early as feasible from all individuals associated with theincident.6.3 Identify all fuel-burning equipment in the site.6.3.1 A parti
21、al list of equipment that might be a potentialsource of carbon monoxide includes gas appliances (furnaces,ranges, 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 On
22、ce all of the fuel-burning equipment has beenidentified, establish and document the condition of the valvesand/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 equipme
23、nt is located inan enclosure that can be defined as a “confined space.”6.5.1.1 Confined spaces are defined in 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 th
24、e equipment has an adequatesupply of air for combustion and ventilation as specified inNFPA 54, chapter 5.6.5.3 Determine whether the equipment, if venting isrequired, is vented to safely carry the products of combustionoutside, as required by NFPA 54, chapter 7.6.5.4 Determine whether any temporary
25、 obstructions of theequipment ventilation, including obstructions of the return airvents have been moved.6.6 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
26、 be carried out. Refer to Practice E678 inplanning any tests.6.6.1 This plan will typically include the turning 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 th
27、e safety officer.6.6.3 Identify any individuals who may have an interest inthe outcome of the testing.6.6.3.1 Such individuals may include the property owner,representatives of the victim(s), equipment manufacturers,equipment service personnel, law enforcement officers, codeenforcement officers, and
28、 the insurance carrier for any of theparties listed above.6.7 Notify individuals who have been identified as possiblyhaving an interest in the testing of the time that the tests aregoing to take place. For additional guidance on notification, seePractice E860.6.7.1 Keep a record of individuals who h
29、ave been notified ofthe proposed testing.6.7.2 Notification of other interested parties may not benecessary 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 identifieda
30、s a potential source of carbon monoxide in the manner inwhich it is designed to be operated, and, using the 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 chimn
