The Real Tragedy Of The Chicago C O Alarm Fiasco Is That It Is Still Crippling & Killing People Today In 2016
” When Vested Interest & GREED get ahead of Technology, R & D & Training, ….. DIASTERS such as the Chicago FIASCO are Destined to follow !”
[The following Data is direct from Chicago Hazmat Chief, John Eversole, as presented and given to me at THE FIREHOUSE Conference in Baltimore, MD.] *** NOTE: Mandatory C O alarm became effective on October 01, 1994.
1. Between October 01, 1994 & March 01, 1995, Chicago, [Chicago proper, suburbs not included], received 17,182 reported C O Alarm Activations to the Fire Department.
2. Between December 22, 23 & 24th, 1994, within one 48 hour period of time they recorded 8,267 C O Alarm Activation calls.
3. Of the 3,465 actually investigated, LESS THAN 1%, only 32 actually had C O Levels of 100PPM or more, [at that time a UL2034 Listed C O Alarm was not required to sound its audible alarm until 100PPM exposure for 90 minutes.
It had become very obvious to Chief Eversole, the MEDIA, and virtually everyone else that 99% or more of the Alarms WERE FALSE ALARMS.
Chief Eversole and everyone knowing the extent of this data was put under a “GAG Order” by the Administration NOT to discuss them with the Media or anyone.
John had Retired before our Meeting in Baltimore.
The Chicago Story
The Chicago Story, actually started in 1988, in Bethesda, Maryland, when the CPSC decided to make Carbon Monoxide, [and Combustible Gases], “Priority Projects” for 1992-93. [It is the CPSC Policy to Select “Priority Projects” 4 or 5 Years in Advance.]
The First “Official” Announcement” of this decision was made in 1988. That is when I was contacted again by Don Switzer, who had been selected as the C O Project Director, and Don, Mark Goldstein, President of the Quantum Group and yours truly, started laying the “Groundwork” for the “Official” C O Project “Kick-Off” in 1992.
Our CPSC C O Project “Team” pushed the formation of a UL CO Committee to start working on a “C O Standard” for Detectors. At the same time we started working with the Canadian Gas Association, to also form a C O Technical Committee to develop a Compatible Canadian C O Standard Requirement.
With these efforts underway,…. THE STAGE HAD BEEN SET! ! !
In November, 1991, ….. FATE ….. STEPPED IN.
On Thursday, November, 07,1991, in Roseville, Minnesota, a Family of Ten, [ 10 ], the entire Family of Doctor Thomas & Ginny Lange were overcome by Carbon Monoxide, and RUSHED to the Hospital in nearby St. Paul, MN, where, … Fortunately, ALL were Saved. [ This incident was later “Featured” on a Rescue 911, TV Program on Tuesday, December 15, 1992].
The VERY NEXT DAY, Friday, November 08, 1991, another Family of Ten, [ 10 ], were FAR LESS Fortunate. The ENTIRE Jesus Orejel Family, were found DEAD in their Brick Home in Chicago.
These TWO, … “Back to Back”, … Carbon Monoxide Poisoning Cases, … were all that the “ASPIRING”, “POLITICALLY MINDED”, Chicago Alderman needed, … He SEIZED the Opportunity to Capture a HUGE amount of PRINT & TV Coverage by “Demanding” Daily, [not the Mayor],… Daily, … Day after Day, …. that Chicago ….. MUST, MUST, MUST ….. Pass a Mandatory CO Detector Ordinance ! ! !
Naturally, the CO Detector Manufacturers, Dealers, & Distributors; as well as the Major Retailers ….. ALL thought that he was a “Gift from Heaven”, ….. and “Backed” his “Play” to the MAX.
I was Contacted by Bob Rivkin, Chicago City Attorney, asking me to come to Chicago as a C O Expert to testify at a City Council Hearing concerning the implementation of the proposed City Ordinance. I accepted the invitation. When called to the Stand to testify, I told them that I probably wanted to see C O detectors in every home more than anyone in the World; however, NOT YET because the Sensor Technology, the Training of our First Responders and Heating Contractors, nor the right Standard had been achieved at that time. I tried to explain to them that I had been selling C O detectors for over 20 years and was all too aware of the nuisance & False Alarm problems and that very few Fire Departments or Heating Contractors even owned the proper equipment to check for C O in a home or structure.
I must say that I was NOT at all surprised to Learn that my “Warnings” , … [ that NEITHER the C O Standard, or the Sensor Technologies, being used in that “Generation” of CO Detectors would Prove to be an Acceptable Solution, due to the resulting, Excessive, “False / Nuisance” Alarms], ….. were Totally Ignored.
Every other witness I heard that day was urging “FULL SPEED AHEAD.”
The Chicago C O Ordinance WAS PASSED, and became Effective, Oct 01, 1994.
Between Oct. 01, 1994, and March 01, 1995, ….. the city OF CHICAGO, [the CHICAGO “AREA” ], ….. Fire Department, … actually “RESPONDED” to … 17,182 … Residential C O Detector Activations.
During a “Temperature Inversion”, on Dec. 21 & 22, 1994, … the CHICAGO Fire Dept. ACTUALLY RESPONDED TO ….. 3,465 ….. C O Detector Activations, [within 48 hours], ….. before saying, ….. Enough, ….. is Enough, ….. and started asking People “IF THEY FEEL SICK ENOUGH TO GO TO THE HOSPITAL, ….. IF NOT, … they were told to ….. “CALL the GAS COMPANY” ! ! ! [ These figures are from a Speech given by: Chief John Eversole, Chief of Hazmat, City of Chicago, at the “Firehouse Conference in Baltimore, MD, in 1995].
The WORST part of this “STORY”, ….. is that 90% of the C O Detectors / Alarms that are “Hanging on the Walls” of the Homes in NORTH AMERICA … TODAY, …… STILL Contain these SAME, … INFERIOR “TYPES” of SENSORS ! ! ! [ Virtually NONE of these SENSORS are MONITORED].
Let us HOPE that other “GOOD INTENTIONED PEOPLE,… DO NOT MAKE THIS SAME MISTAKE, …. ON AN EVEN LARGER SCALE” ! ! !
I would like to Point Out that “MOST” of the Claims being made by C O Alarm Manufacturers that they have Vastly IMPROVED their Products, which has Greatly Reduced the Number of False / Nuisance Alarms, ….. is a Big Bunch of B/S.
The reason that the Number of C O Alarm Responses made by Fire Departments and Utility Companies has DECREASED, ….. is Because, as the GRI Report reveals, ….. that 75.4% of the people answering their Survey said that when their C O Alarm Activates, ….. they call NO ONE !
They have “Heard” about ALL of the “Defective” C O Alarms, and “JUST ASSUME” that it is a
“FALSE ALARM”. …….. A SERIOUS PROBLEM ……….. BECAUSE when you IGNORE the Warning of an Alarm, ….. IT CAN KILL YOU …..
“FALSE ALARMS ………. DO KILL” if the cause you to ignore the REAL WARNING.
Part two _ Be Aware _ Let’s Talk Sense & Sensors
Be Aware/Sensor Info
Warning ! ! !
IF…. Your are involved in CONSIDERING writing a Carbon Monoxide Ordinance, By-Law, or any form of Mandatory Requirement for your City, County, State, Province, or Nation, … it is IMPERATIVE that you consider the LONG TERM IMPACT that such action can CREATE for your Citizens, … and your First Responder Teams.
Therefore, there are a number of VERY IMPORTANT FACTS that you NEED to KNOW that have been Very Successfully and Intentionally HIDDEN from the Public, the CPSC, the Fire/Rescue Responders; as well as the HVAC and Utility Company Investigators.
Let’s Talk Sensors, … and COMMON SENSE!!!
Like EVERYTHING in LIFE, there IS a “REASON” for EVERYTHING; however, it is Often VERY DIFFICULT for many of us to understand THE REAL REASON WHY.
“COME NOW LET US REASON TOGETHER”:
Up to October, 1998, … 99% of ALL CO “Detectors” in North America were either MOS (metal oxide or tin oxide, solid state, semi-conductor) Sensors, … or “Color-Metric”/Bio-Mimetic/Chemi-Optic type Sensors. Herein Lies the Problems!!!
EVERY MOS Sensor Type CO Alarm (or Detector) EVER Produced WILL go into FULL FALSE ALARM at the “END of LIFE”, unless it has become contaminated and KILLED … EVERY ONE … EVERY TIME!!!
(A former Exec VP of Marketing of American Sensors actually “Bragged that this made their detector Fail-Safe”, in a Fax sent to Distributors in May of 1999).
This means that EVENTUALLY AT LEAST ONE CO Alarm/Detector RESPONSE to EVERY HOME/DWELLING that contains such a Product is GUARANTEED!!!
Unfortunately, this FINAL “End of Life” Response is often ‘Preceded’ by Several Previous “Nuisance” ALARMS, due to the “Super-Sensitivity” caused by Sensor Aging. (At this point in Time, … these products WILL NOT Reset, or Silence, without removing the Power Source.) In addition, these Sensors are GREATLY EFFECTED by Changes in HUMIDITY. FAR MORE SENSITIVITY in HIGH HUMIDITY, … FAR LESS SENSITIVITY IN LOW HUMIDITY CONDITIONS.
GRI, [Gas Research Institute], collected and documented a large volume of Reports on CO Detector / Alarm “Responses” to C O Alarm activations over the years 1994-99. Among the many items covered in these Reports was the “TYPE” of Sensor Technology used in the CO Alarms that resulted in the CO Responders Investigation.
The following Chart indicates Very Clearly, that as the “Average Age” of the CO Alarms in our Nations Homes Increases, … so does the “Percentage” of these “Un-wanted / Nuisance” Alarms that are using a MOS, [Metal Oxide Semi-conductor], type of Sensor.
The scope of this Problem will continue to Increase EVERY DAY until these products are REMOVED from the homes in our Nation.
NFPA 720, Guidelines on the Installation and Maintenance of C O Alarms says that C O Sensors are to be Calibration Certified, [Checked], every three years. Since this is NOT practical in the case of “Residential Single Station C O Alarms”, it is the recommendation of C O – Experts that ALL Residential Detection / Alarm Products should be REQUIRED to have an Automatic “Kill Switch” installed to indicate the “End of Useful Life”, … WELL BEFORE this Excessive Nuisance Alarm age is reached.
EVERY Color-Metric/Bio-Mimetic/Chemi-Optic sensor type CO Alarm (or Detector), that has not become inoperative due to a Dead Battery, or some other cause of failure, WILL go into a FULL FALSE ALARM. (At this point and Time, … These products WILL NOT Reset, or Silence, without removing the Power Source.
The HUMIDITY EFFECTS are Very Similar to the MOS Sensors.
This Sensor Technology was Invented by the University of California, … the patent was acquired by Mark Goldstein, President of the Quantum Group, and shortly prior to the CO Detector UL-2034 “Introduction” on April 30, 1992, was Licensed EXCLUSIVELY to First Alert, for “Retail” Sales. This “Exclusive” was later revoked, and today this Sensor is being used by several Companies.
Because of this “Exclusive” Patent arrangement from ‘Prior’ 1992, to ‘about’ 1995, … EVERY OTHER CO Detector SOLD in North America during this Period, … HAD TO BE A MOS TYPE SENSOR PRODUCT!!
Also, because the MOS Sensors of that ERA required so much ‘Power’ to make the Sensors function Properly, they HAD to be 120v, ‘Plug-in’ Detectors. This FACT meant that First Alert had the ONLY ‘BATTERY POWERED’ CO Detector on the Market.
Unfortunately, this fact, resulted in the INCREASE OF ‘Mis-Information’ on CO Alarm installations by virtually EVERY OTHER Manufacturer throughout the Industry. The ‘Marketing Decision’ was made that since the MOS Products HAD to be ‘Plugged In’, and that meant EITHER a ‘Cord Hanging Down the Wall’ or the ‘Expense’ of Installing a ‘Recessed Clock Receptacle’, or a ‘Junction Box’ for a Direct ‘Hardwired’ Detector, … these ‘Factors’ resulted in a VERY BAD, and ‘DEADLY’ DECISION that was ‘MADE’, ‘Advertised’ and ‘Vigorously’ Promoted.
With the ‘SUCCESSFUL REVERSAL of FACTS’ that the CO Alarm Manufacturers had seen occur in the IONIZATION Sensor (for Smoke Detectors), and the ‘Residential Sprinkler’ Industry, … and in my Opinion with the ‘Blessing and Participation” of NFPA, … they TOO said: “We can make up a ‘STORY’ that sounds ‘Half-Way’ feasible, and it will fly”.
So, comes the ‘Story’ that since the ‘Specific Gravity’ of Carbon Monoxide (98.6 at 68 degrees F) is about the SAME as ‘Normal’ Air, … it is OK to ‘Mount’ the CO Alarm down by the floor, and because it will ‘MIX’ … (Eventually), with the Air in the ROOM, sufficiently to cause the Alarm/Detector to activate before the CO reaches a ‘Fatal’ Concentration for the ‘Average’ Healthy person.
While I can accept this to be true, in many cases, unfortunately, it CREATES another EXTREMELY Dangerous and LIKELY scenario that is as follows:
Mrs. Jones purchases a ‘Direct Plug-in’ CO Alarm, goes home to install it, and them has the Problem of Deciding WHERE to plug it in. The process of thought goes something like this: “No, I don’t want to put it there, because that is where I plug in the Vacuum Cleaner, … and not there, because that is where the Kids plug in their toys or record player, etc., … Where do we have a receptacle the is NOT being used, … Oh yea, there is one Behind the Couch, or Behind the Drapes,” … or … some other place WHERE IT DOES NOT BELONG for EARLY DETECTION, … and LIFE-SAFETY!!
PROPER PROTECTION REQUIRES PROPER PLACEMENT / INSTALLATION, THE ‘PROPER’ PLACE, … Not Always,….. “as per Manufacturer’s Instructions”.
One absolute FACT that never changes is:
“NO DETECTOR IN THE WORLD, MINE OR ANYONE ELSE’S, CAN GO INTO ITS WARNING MODE, UNTIL WHATEVER IT IS DESIGNED TO DETECT REACHES ITS SENSOR.” GEK
Important GRI Testing Conclusions:
One of the Most Important and Revealing Charts in the GRI, Topical Report Issued in March, 2000, Titled: “Carbon Monoxide Response Survey Analyses: FINAL Supplement 1994-99, was a Chart depicting the Percentage of Very Low, or Zero, CO Concentrations actually found during CO Alarm / Detector Responses between October, 1998, and April, 1999.
I believe that this is a DIRECT reflection of the Increased percentage of CO Alarms utilizing MOS type Sensors, following the Chicago “Nightmare”, [which was generally blamed on “Color-Metric” Technology problems].
The combination of these Growing Numbers, as well as the “Aging” of the MOS Detectors sold in the 1992-98 years, and the fact that once the “Filters” in these Sensors get soiled, they react to many, many different gases, [thereby causing “Truly False” Alarms], these factors combined to result in the following HIGH Percentages of 0 to 9 ppm CO discovered during First Responder Investigations.
1. First Alert ………………………….. 84.2 %
2. Nighthawk …………………………. 52.5 %
3. American Sensor ……………….. 43.3 %
Maybe this is WHY that by 1997-98, the MAJORITY of the people surveyed said that when their CO Alarm Activated,….. THEY CALLED NO ONE….. to “Check-Out” the Potential Problem ! ! !
The Complete GRI Conclusions found on page 57 follows:
“The volume of CO alarm activations investigated by utilities participating in this project has fallen in each of the last two years. The decrease in demand for investigations following activations is surely a welcome development for responders, reducing their costs as well as the strain on their resources. However, the question of why this demand is diminishing is an important one that is as of yet unanswered.
Assumptions that this trend is due to an improvement in alarm performance are not supported by the data from this project since no increase was recorded in CO levels measured following activations (as would be expected if there were fewer nuisance activations). With alarms activating at roughly the same CO levels measured in previous seasons the obvious question becomes “What is causing the drop in investigations volume?” One possible scenario is that residents are not calling utilities for help following activations as often as then did in earlier years (Kramer and Tikalsky, 1999), found that a majority of July 1997 through June 1998 alarm activations in four North American Cities were not reported to responders). If this is indeed happening, it would call into question the contribution alarms are making to resident safety.
The new gradually emerging CO detection technologies (i.e., electrochemical and infra-red) may show different activation characteristics. These technologies have yet to see the kind of widespread exposure to residential conditions experienced by the two more-commonly available technologies.”
In 1995, a THIRD SENSOR TECHNOLOGY was introduced into the Residential CO Alarm Market by George E. Kerr & AIM Safety. The ELECTROCHEMICAL SENSOR has been Successfully used for Industrial/Commercial Gas Detection/Investigation for 20 years or more.
This Technology was considered far too expensive to be used in the Residential Market back in 1991 – 92, when Earlier Versions of C O Alarms/Detectors were being Developed.
While a Good Electrochemical Sensor is FAR MORE ACCURATE, RELIABLE and REPEATABLE than other Sensors now available, … Contrary to the two previously discussed Technologies, this type of Sensor will Decrease in Sensitivity to C O as it ages, … and eventually will FAIL to DETECT C O at a Level necessary to Guarantee Life-Safety. Unfortunately, Most C O Alarms WILL NOT go into a ‘Fault or Error’ Warning when the Sensor has Drifted BELOW SAFE LEVELS!!!
(Extensive testing prior to the 1999 Recall of a Million Kidde-Nighthawk and LifeSaver CO Alarms / Detectors revealed that NONE, ZERO, had provided a ‘Warning’ that the Sensor had Failed Totally !
The ‘DRIFT’ Characteristics of all three of the Commonly used Sensors Reveals very clearly, the Urgent need C O Alarms to be required to have “Monitored Sensors.”
The 1992, 1995, and 1997 (Effective Oct.’ 1998), … ALL three contained a statement indicating that “Every Primary Component that’s Failure could cause the Alarm/Detector to FAIL to Alarm, … MUST be Monitored … EXCEPT the SENSOR!!!
The CURRENT PROPOSAL, STILL DOES NOT REQUIRE THAT THE SENSOR, … MUST BE MONITORED!!!
It is my personal and professional recommendation is that any & all C O Alarms mandated by Building Codes or By-Laws must specify that only C O Alarms, Detectors or Monitors must provide protection from Chronic Low Level C O Poisoning by sounding a minimum 85db Audible Alarm at 10PPM or less, must monitor Sensor activity; as well as having an automatic “Kill Switches” at or prior to 7.5 years from “Date of manufacture be considered accepted as in full compliance with required specifications.
