For those short term applications we have starting carrying the SafeAir Ozone Badge for ozone detection.
These ozone badges are used for worker safety in environments that may have elevated ozone levels. Time weighted badges are used for intervals between 15 minutes and 48 hours (depending upon ozone levels). As Osha regulates ozone exposure based on a a TWA (time weighted average) these badges are the perfect solution for short term worker safety.
The SafeAir ozone badge is a monitoring system designed to indicate the presence of ozone at concentrations at the permissible exposure limit. The SafeAir ozone badge detects the presence of ozone by forming a color change in the shape of an triangle with an exclamation mark inside. This indication is produced by a color-forming reaction which occurs when ozone reacts with a flat indicator layer.
We have found many interesting applications for these badges. Should you have an issue with other gasses that are cross-sensitive causing your HMOS, or electrochemical ozone sensor to provide inaccurate readings of ozone, the ozone badge can verify or at least ensure your workers are indeed safe.
We used these badges on a groundwater remediation site where in-situ ozone sparge wells were installed on the property of a personal residence. The owner of the residence was concerned with ozone levels above ground. At no time on-site was the operators of the ozone system able to detect ozone. Placing an ozone badge on the front door of the residence daily proved that ozone levels were not unsafe, and were not occurring during evening hours. This was a low cost way of ensuring human safety and resolving a PR issue.
Carbon Monoxide (CO), is often called the “Silent Killer” because of its ability to take lives quickly and quietly when its victims never even knew they were at risk. It is indetectable to humans, being both tasteless and odorless, and in high enough concentrations it can kill within minutes. But CO is not so silent if you read about its victims in the news. It already claims hundreds of lives each year, and survivors of CO poisoning can be left with psychological and neurological symptoms. Sadly, this toxic gas takes lives that could be saved through education, awareness, and simple protection. Read this article to make yourself aware of the risks that CO poses, and how to stay CO safe!
CO is a poisonous gas produced by the incomplete burning of carbon based fuels. When inhaled it deprives the blood stream of oxygen, suffocating its victim. No one is immune to the effects of CO, though children 14 and under are more likely to sustain poisoning than adults at lower levels. CO can cause immediate health problems, and even death, in high concentrations, and some suspect it can also cause long-term health problems in low concentrations if a person experiences regular exposure (such as at home, or in the workplace). Significant exposure to CO can also reduce life expectancy, as reported in arecent articleof the Journal of the American Medicine Association.
Any gas or propane based engine will produce CO, meaning thatboaters, truckers, and small aircraft pilots are at risk from CO fumes as soon as they start their vehicle. Homeowners suffer the most from CO poisoning, and are in danger from sources like gas-powered furnaces and water heaters, clogged fireplaces and chimneys, cars running in an attached garage, and burning of fuels indoors (such as a gas or charcoal grill).Travelersstaying in hotels are in danger of CO poisoning as well, which can be leaked into a hotel room from nearby faulty heaters and boilers. To see examples of recent CO poisonings in all of these areas, and others, take a look at our newsheadlinespage.
The beginning symptoms of CO poisoning are sometimes compared to the symptoms of food poisoning. Depending on the level of CO, and length of exposure, you may experience any one or more of the following symptoms:
weakness and clumsiness
nausea and vomiting
quick irregular heartbeat
disorientation or confusion seizures
Most people have experienced some of these symptoms at one time or another, which doesn’t necessarily mean that CO poisoning caused them. However, regular occurence of any of these symptoms might be an indication of CO poisoning. For example, do you suffer from any of these symptoms on a regular basis, or always in the same place? For example, do you regularly get headaches after entering your home, or when operating your vehicle. Do your symptoms go away when you leave the house or your vehicle? Have several members in your house been complaining of the same symptoms? If the answer to any of these questions is ‘yes’, then you might be suffering from the effects of CO exposure. But symptoms and problems don’t just appear when a person is exposed to high levels of CO. Even low-level CO concentrations can cause health problems if a person is exposed to them for long periods of time on a regular basis. This excerpt from an article published by the EPA explains why:
The health threat from lower levels of CO is most serious for those who suffer from heart disease, like angina, clogged arteries, or congestive heart failure. For a person with heart disease, a single exposure to CO at low levels may cause chest pain and reduce that person’s ability to exercise; repeated exposures may contribute to other cardiovascular effects. http://www.epa.gov/air/urbanair/co/hlth1.html
Ultimately, the best way to determine if you are being exposed to CO in your environment, particulary in low-levels, is with a CO detector. Large, wall-socket CO detectors sold in hardware and drug stores may protect you from a high-level leak of CO in your home. Generally though, these detectors do not alarm at low-levels of CO, and also offer no way to measure the actual concentration. Also, to avoid false alarms, such detectors require several continuous minutes of exposure at high-levels before alarming. But by this time, you may already be suffering from the effects of CO poisoning – disoriented, sick, and wondering what is going on. Such home detectors also give you no way to test that they are still working. Don’t be fooled by the “Push to Test” buttons on these detectors.This button tests the audible alarm, but typically doesn’t check if the actual CO sensing element is still functioning. A better way to stay safe, both at home and when away, is with a portable CO monitor that has a digital readout. This allows you to monitor levels anywhere in your environment, no matter where you are. It also gives you the ability to routinely test the detector with a small source of CO (like a blown-out paper match, or CO bump kit).Learn moreabout the Pocket CO portable detector/dosimeter, a way to keep you and your family CO safe!
The level of CO concentration is measured using a system called Parts Per Million (PPM). For example, 100 PPM CO means that for every 999,900 molecules of air, there are 100 molecules of CO. CO effects people differently depending on the concentration. In addition to measuring the current level of CO concentration, another measurement used is the Time-Weighted Average (TWA). This measures your average exposure to CO over time, and is also measured in PPM. For example, if you were exposed to a large dose of CO in the begining of the day, but none afterwards, your TWA for the day would be low, since for most of the day you had no exposure. If, however, you are continually exposed to 20 PPM CO throughout the day, your TWA for the day will be 20 PPM.
The table below summarizes some health effects due to prolonged exposure to various concentrations of CO, as well as some government recommended limits, and Pocket CO alarm levels. It has been compiled from various sources, including the NFPA:
Level of CO
Health Effects, and Other Information
Normal, fresh air.
Maximum recommended indoor CO level (ASHRAE).
Possible health effects with long-term exposure.
Max TWA Exposure for 8 hour work-day (ACGIH). Pocket CO TWA warning sounds each hour.
Maximum permissible exposure in workplace (OSHA). First Pocket CO ALARM starts (optional, every 20 seconds).
Slight headache after 1-2 hours.
Second Pocket CO ALARM starts (every 10 seconds).
Dizziness, naseau, fagitue, headache after 2-3 hours of exposure.

Headache, nausea, and dizziness after 45 minutes; collapse and unconsciousness after 1 hour of exposure.
Death within 2-3 hours.
Loss of consciousness after 1 hour of exposure.
Headache, nausea, and dizziness after 20 minutes of exposure.
Death within 1-2 hours.
Headache, nausea, and dizziness after 5-10 minutes; collapse and unconsciousness after 30 minutes of exposure.
Death within 1 hour.
Death within 30 minutes.
Immediate physiological effects, unconsciousness.
Death within 1-3 minutes of exposure.
There are many CO exposure limits set by government organizations. For a detailed listing, clickhere. The American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) lists a maximum allowable short term limit of 9 PPM. And the EPA has set two national health protection standards for CO: a one-hour TWA of 35 PPM, and an eight-hour TWA of 9 PPM. These standards make it clear that any carbon monoxide reading over 9 PPM should be investigated and acted upon.
Motorboats can release CO at very high concentrations. The CO can accumulate in and around the boat when idling, and can even be dragged behind the boat in what’s known as the “station wagon effect”. Learn more aboutCO safe boating.
CO on houseboats can be released not only by the motor, but also by the onboard generator. Many deaths have occured on houseboats due to CO accumulating in cabins, and in areas around (and under) the boat where children often swim. Learn more aboutCO safe boating.
Small aircraft pilots are susceptible to CO leaking into the cabin from the engine. Such leaks could be at low concentrations, but over long periods of exposure they could cause heath problems.
Because of their long drives and therefore long exposure periods, truckers are especially vulnerable to low-level CO leaks in the cab. Such leaks can put their lives at risk, as well as the lives of others on the road.
Many people have been sickened, and some have even died, due to CO poisoning at motels and hotels. CO can leak into a traveler’s room from nearby leaky furnaces and hot water heaters. Despite this risk, most hotels do not have CO detectors installed.
The largest group that suffers from CO poisonings are homeowners. CO can accumulate in a home from faulty gas-powered furnaces and water heaters, clogged fireplaces and chimneys, wood burning stoves, running cars in attached garages, and any burning of fuels indoors (such as a grill). Also, some homes or businesses located next to multi-lane, busy streets or highways, can have low-levels of CO present much of the time.
ThePocket CODetector/Dosimeter, can protect your and your family from dangerous levels of CO anywhere. Its loud alarm and bright red light will warn you of dangerously high levels. It is simple to use, weighs less than an ounce, and fits on a key chain. Also, Pocket CO’s digital readout allows you to monitor even low levels of CO.
A great case study on the use of the Aeroqual Series-500 was done by the University of Birmingham to evaluate No2 levels real-time in cities.
Due to the portability of the Series-500, and the low level accuracy of the NO2 sensor head, along with data logging the researchers were able to record data in various locations throughout the city quickly and efficiently to determine small areas of dangerous NO2 levels.
The Series-500 was invaluable as it portable, lightweight, and can record data quickly and for long periods of time.
Also available today is a dual sensor NO2 + O3 in the Series-500. This will allow for simultaneous data logging of NO2 and O3. If used with the optional temp and RH meter the Series-500 would be capable of logging data from the NO2, O3, Temp, and RH sensors showing a relationship between the gasses and ambient conditions.
The Aeroqual Series-500 has become a great monitor for portable gas detection, and accurate gas detection for toxic gas measurement. As the cost of GSS type sensors is much lower than traditional UV analyzers the industry has been slow to adopt the Series-500 and accept the use. However, case studies, and white papers show again and again that the Series-500 has a place in environmental monitoring.
Low-power, and relatively low-cost, gas sensors have potential to improve understanding of intra-urban air pollution variation by enabling data capture over wider networks than is possible with traditional reference analysers. We evaluated an Aeroqual Ltd. Series 500 semiconducting metal oxide O3 and an electrochemical NO2 sensor against UK national network reference analysers for more than 2 months at an urban background site in central Edinburgh. Hourly-average Aeroqual O3 sensor observations were highly correlated (R2 = 0.91) and of similar magnitude to observations from the UV-absorption reference O3 analyser. The Aeroqual NO2 sensor observations correlated poorly with the reference chem-iluminescence NO2 analyser (R2=0.02), but the deviations between Aeroqual and reference analyser values ([NO2] Aeroq [NO2] ref) were highly significantly correlated with concurrent Aeroqual O3 sensor observations [O3] Aeroq. This permitted effective linear calibration of the [NO2] Aeroq data, evaluated using hold out subsets of the data (R20.85). These field observations under temperate environmental conditions suggest that the Aeroqual Series 500 NO2 and O3 monitors have good potential to be useful ambient air monitoring instruments in urban environments provided that the O3 and NO2 gas sensors are calibrated against reference analysers and deployed in parallel
The Series-500 now is available with a dual NO2 and O3 sensor head to make measurement of NO2 and O3 simple. With the data logging features the Series-500 is a valuable tool in environmental monitoring.
Recent news articles have brought our attention to the potential hazards of CO Poisoning on boats. While this is something we know could happen we did not realize how prevalent and dangerous this could be until a customer called this week, concerned about the safety of the skiers on his boat.
A simple CO Monitor could have saved many, if not all of these lives and prevented injury.
There Are CO Monitors installed in the cabin of many larger boats. However, smaller vessels have none, and the outdoor ski area of boats is unprotected. This is where Sarah Pool, of Texas was when she was overcome with Carbon Monoxide. As she was watching other skiers and enjoying the summer on the ski platform of a smaller vessel, she was slowly and silently overcome with Carbon Monoxide. As she had no life-jacket on when she did pass out and fall in the water, she was unable to yell for help, or help herself.
A simple and low cost, handheld CO monitor may have saved her live. Using these portable, yet rugged CO monitors could alert of danger and be the difference between a catastrophic weekend and a great weekend out on the water.
