The Case for Carbon Monoxide Protection Presented to the Code Technology Committee of the International Code Council Detroit, Michigan September 22, 2005
Wendy Gifford • Director, External Affairs, Invensys • Vice Chair, National Electrical Manufacturers Association Carbon Monoxide Section • Member, NFPA 720, Standard for the Installation of Household Carbon Monoxide Warning Equipment
Objective • To present the compelling evidence that will provide the Code Technology Committee the justification to mandate carbon monoxide protection in new and existing dwellings.
Committee Draft Recommendation • Not “sufficient justification” for mandating carbon monoxide protection. • Death and injury data • Cost/benefit calculation • Detector/standard questions
Injuries are significant;Alarms offer effective solution • Carbon monoxide poisoning causes 10,000 injuries a year. • Long term consequences • High societal costs. • Carbon monoxide alarms provide affordable, reliable protection appropriate to a building code.
Carbon Monoxide Causes Many Injuries • Carbon monoxide kills and injures more people than all other poisonings combined. • More than heroin
One third may go undiagnosed • “Significant under reporting of CO deaths.” • “Misdiagnosis commonly occurs.” • “Many non-lethal exposures go undetected”
Total injuries exceed 15,000; most in homes • 2001-2003 data Centers for Disease Control • Every year--- • 15,200 people treated • 480 deaths • Majority (64%) of non-fatal exposures occur in homes.
CPSC: Nearly 200 died • 2002: Estimated 188 carbon monoxide poisoning deaths associated with the use of a consumer product • Excludes those in which source is a vehicle, even if in home
Decline in deaths may be artifact of statistics • “Part of the decrease from the 1994-1998 average annual estimate of 200 . . . To an average of 141 in 1999-2002 may be the result of . . . A new methodology.”
Injuries vastly outnumber deaths • For every residential carbon monoxide death, there may be 51 injuries. • 9,728 annual injuries (CDC Data) • 188 deaths (CPSC Data) • 10,000 seek medical attention or miss work each year
Even these numbers may be underreported • Furnaces were the source in 46% of nonfatal CO poisonings • Only 10% of fatal poisonings. • “This suggests that the role of home heating appliances is prominent in the large group of underreported nonfatal exposures.”
CO poisoning affects the most vulnerable • Death rate highest among 65+ • Injury rate highest among children <4 • The fetus is particularly vulnerable. • Non-English speaking populations overrepresented
The effects are not always temporary or reversible • Significant after effects • Heart • Brain
Carbon monoxide injuries can affect the heart. • Nearly 40% of patients with moderate to severe carbon monoxide (CO) poisoning will have cardiovascular manifestations.
Neurological injuries can cause long term affects • Delayed neurological dysfunction (brain damage) occurs in 14% to 40% of serious cases. • Presents after patient appears “recovered” (2-40 days) • Cognitive defects, memory impairment, learning • Difficulty moving • Personality changes
Can impact ability to work • One third of CO poisoning victims may have subtle but lasting memory deficits or personality changes. • In a 3-year follow-up of 63 CO poisoning survivors, Smith and Brandon found that 33% showed evidence of personality deterioration and 43% reported memory impairment.
Significant nerve damage can occur. • Parkinson's Disease • Persistent vegetative state • Agnosia, • inability to recognize and identify objects or people • Apraxia • Voluntary movement impaired
Nerve damage, continued. • Mental deterioration, • Urinary or fecal incontinence • Gait disturbance • Visual impairment/Blindness • Amnestic/confabulatory state • Psychosis
Hefty societal costs • Lost work time, productivity • Temporary • Permanent • Long term treatment • Health care costs • CPSC estimates >$630 million societal costs annually
Not having protection can be expensive legally CARBON MONOXIDE CASE SETTLED FOR $30 MILLIONSouth Florida Sun-Sentinel; Fort Lauderdale, Fla.; May 26, 2001; Akilah Johnson Staff Writer Seven people who suffered brain damage after moving into or visiting the Terra Cotta Place Apartments will collect more than $30 million from complex owners and managers for failure to fix a water heater that was leaking carbon monoxide.
CO alarms are highly effective in reducing exposure. • American Journal of Emergency Medicine study of 911 calls: • “Persons with CO detectors were less likely to become symptomatic.” • Only 13% symptomatic vs. 64% of those without alarms.
Mecklenburg County requires in all homes. • Ice storm power outage: 161 people with confirmed CO exposure; 1 death • 88% of the cases of symptomatic CO poisonings occurred in homes with no reported functioning CO alarm. • Mecklenburg County changed ordinance to require battery back up; all homes
Alarms are already saving lives. • Any discussion of a decline in death rates should consider growth in home carbon monoxide alarm use since 1994. • Estimates 25-35% household penetration.
Current requirements • States • Alaska, Connecticut, New Jersey, New York, Rhode Island, Texas (group homes/day care), West Virginia, Utah, Vermont • Cities & other AHJs • Chicago, New York City, and 30 others
Cost of compliance lower than assumed • Significantly below committee estimate of $300-$500. • Typically one per home • NFPA 720: One outside each separate sleeping area
Smoke/CO combo units eliminate extra labor • New construction (AC/DC): • Combo alarm = $35-$52 • Incremental = $15 over smoke alone • No incremental labor • Annual $6.15 (annual battery + 5 year life) • Existing homes (battery) • CO alarm $20-$42 • Annual $11.40 (annual battery + 5 year life)
UL Testing confirms reliability • Over five years, in home samples regularly tested to UL 2034 requirements in lab • Alarms “have performed in an effective manor.” • 2 alarms alerted consumers to CO accumulations in homes • In lab checking, 1 late alarmed; 1 false positive.
CPSC Support • CPSC goal: additional 20% reduction in deaths by 2013 • CPSC continues to recommend CO alarms • Tested alarms did not “expose consumers to a significant health risk” with one exception
Centers for Disease Control highlights the role of alarms • “Yes, people can prevent carbon monoxide poisoning by taking some simple precautions, including making sure that: • “carbon monoxide detectors are properly installed and maintained in homes, houseboats, workplaces, and other appropriate places;”
Standards development for CO alarms similar to smoke alarms • ANSI UL 2034, carbon monoxide standard • Three major changes in first 12 years of standard. • UL 217, smoke alarm standard • Half a dozen changes in first 12 years after alarms were first required in residences. Meanwhile, lives were saved. • Don’t wait for the “perfect” standard.
CO protection is appropriate to a minimum standard • UL 2034 life safety standard, not health standard • Allows levels far in excess of agency recommendations for outdoor air and the workplace.
Comparative CO limits • Environmental Protection Agency • Outdoor air: 9 ppm/8 hours; 35 ppm/1 hour • ICC IMC • Parking garage: 25 ppm/1 hour requires ventilation • American Conference of Governmental Industrial Hygienists • 25 ppm/8 hours • National Institute for Occupational Safety and Health • 35 ppm/8 hours • Occupational Safety and Health Administration • 50 ppm/8 hours • UL 2034 = ignore 30 ppm/30 days; 70 ppm/1 hour
The least we can do is offer some protection in the home where the most vulnerable population spends the most time.
Not for profit organizational support • American Lung Association • Home Safety Council • National Safe Kids Campaign • Residential Fire Safety Institute
Evidence is compelling. • Residential carbon monoxide deaths and injuries are a major problem. • Long term implications and societal costs are significant. • We have the tool right now to protect lives.
Conclusion • The Code Technology Committee has the opportunity to lead. • We ask you to recommend carbon monoxide protection for dwelling units and start saving lives.
