2020-05-21: € 9 Billion Lufthansa Bailout by German Government

"The two seats on the Supervisory Board should now be filled with experts who are aiming for Lufthansa's economic recovery and not pursuing a political agenda." (Handelsblatt quoting a politician.)
If this is the deal - even with that much of government money - Lufthansa (and the rest of the aviation industry) will again not be forced to adhere to the law when it comes to aircraft cabin air.

Far too often there is a CACE (Cabin Air Contamination Event) somewhere in the world to allow me to offer here an exhaustive list of such events. I have added here just a few quite extreme events once I came accross them and found time to look into them a little. In most cases, I just refer to Aviation Herald. Only occasionally, I have added something on my own. Aviation Herald is a good source, but also at times struggles to report about all CACEs. As I said, CACEs are just far too often. We need to change that!

EasyJet to go for Cabin Air Filtration in the Recirculation Path

Pall had announced already on 2016-12-05 (Web.Archive) that EasyJet would retrofit their fleet of A320 family aircraft with the latest Pall Aerospace PUREair Advanced Cabin Air Filters [in the recirculation].

 

Action

CO Detectors

Sensors have been demanded by pilots and cabin crew for years, but they are still not introduced on board. There may be good reasons for NOT introducing air quality sensors on passenger aircraft. However, every individual on an aircraft may decide to get informed and this can not be denied. Therefore, immediate action could be taken without waiting for the ultimate industry solution of the problem - which may never come. This is especially important in failure cases like fume events. Failures compromising cabin air quality may alert people on board, but it may need some kind of objective confirmation before action can be taken. Situations with cabin air quality problems could also pass unnoticed without sensing. If cabin air is contaminated, it will show a mixture of many substances. Carbon monoxide (CO) will most probably be one of these substances. Simple logic tells us that it is sufficient to trace one bad gas in an abnormal quantity to conclude that the cabin air is not ok. CO is taken from the cocktail to be measured, because inexpensive and small CO detectors are available on the market. Pilots (cabin crew, passengers) should read the carbon monoxide (CO) concentration from a personal CO detector as an objective indicator in addition to the observations from their senses (nose and eyes). It is known from CO measurements on the BAe 146 that the CO concentration will be low even in a fume event [1]. For this reason, the CO concentration should not be compared against the limit value of 50 ppm (CS 25.831), but rather against values obtained under normal conditions (e.g. 2 ppm; as a frequent flyer you will find out for yourself soon).

[1] Global Cabin Air Quality Executive: Carbon Monoxide Database Collated on 345 BAe 146 Flights in UK, 2003-2004, 2006 (access difficult, but contact GCAQE for more information if you are desperate)

Feel free to report/share your findings. E.g. take a picture of your CO detector with its reading (maybe with a fume filled cabin in the background) and report about what happened to people during that flight. We may all learn from this collected information.

I have expressed the above view in my presentations and have been asked where inexpensive(!) CO detectors can be bought. Looking on the Internet myself, I discovered these links:

Inexpensive Instant CO Sensors:
UYIGAO UA6070 CO Detector (identical to KXL-801) --- Features: loud alarm
KXL-801 CO Detector (identical to UYIGAO UA6070) --- Video Test
KKmoon GM8805 CO Detector --- Features: data hold, alarm threshold can be set. Video Test. Manual (PDF)
AS8700A CO Detector --- Features: data hold
HT-530 CO Detector --- Features: clip to attach to clothes
KXL-601 Mini CO Detector (low budget device) --- User report: "very inaccurate", "not recommended"

Remark:

Affordable CO Datalogger:
Lascar Electronics EL-USB-CO300 Carbon Monoxide Datalogger

Remark:

 

Breathing Masks

Each member of the cockpit crew is protected by one onboard oxygen mask. Oxygen comes from a bottle and is available for the rest of the flight. Cabin crew have (at best) a smoke hood for their protection. The chemical oxygen supply in the smoke hood is intended only for short duration. A private breathing mask can protect people in the cabin in the very rare event of air contamination. A breathing mask filters the air and will do so for the rest of the flight. Inexpensive are the army standard breathing masks. Buy only new masks. Germany: "Bundeswehr Schutzmaske M65" (by Dräger). Better suited is a civil mask like the "Dräger X-plore 6300 Full Mask". It has a standardized 40 mm threaded filter connection. A suitable filter would be the "Dräger X-plore A2B2E2K2HGP3". This is a "combined filter" for "organic gases and vapours" (A), "inorganic gases and vapours" (B), and other substances.

Also this information is provided here; because I have been ask for it. Cabin crew members are increasingly concerned. Some already have a personal breathing mask in their carry-on baggage or intend to do so. By asking cabin crew members to consider to carry a breathing mask (in order to be prepared for a very unlikely event), I do NOT state that cabin air can be compared to the air after an attack with chemical weapons. What I argue is only this: A breathing mask (with a suitable filter) will protect people in "harsh environments". I do NOT consider the aircraft cabin such a "harsh environment". Therefore, a breathing mask will give sufficient protection in such cases where people have (claimed to) become ill in the aircraft cabin due to (potentially) contaminated cabin air. Employers have a legal duty to protect their employees. If employers do not act accordingly, cabin crew have the right to take measures themselves as deemed necessary.
