Co poisoning

[4th ski-doo]

How much did I suck back in the day when we was bare footing off the platform?

Cats hide the nauseous fuel odor, CO is odorless, colorless, and tasteless. Bonds to hemoglobin 200 times stronger than oxygen.

We got more numbers today. Once we get the data I will pass it along. I do own a FAE so we will do the test again with FAE. We are also testing a fishing boat with outboard motor and a I/o just to see if co is a risk on different vessels. Anyway I will pass data along as we get it. The alarms where ringing on the monitor at surf speeds so it should be interesting.

You can send that monitor over to Saskatoon afterwards and we can make this a multicentered study

[ffmedic74]

Is your wife running the data through spss and doing all the fun statistics?

[Live to surf]

What kind of residency is she doing where she would do this kind research? Neurology? Public Health? Just trying to guess.

I hope Larry from fresh air does not does not jeopardize the legitimacy of your research, I have no reason to think other wise, but when you have someone that can profit from the out come, one will always wounder if data has been tainted .

I have seen results from one study on the internet, about a large lake in Europe, that had one marina, in a narrow inlet. All the boat traffic had to go through the inlet, to go into the main lake.
They tested the water in the inlet, in the lake where there was average boat traffic, and remote places of the lake.
The inlet was one of the least polluted areas of the lake. The conclusion, the boats add pollution, but the turbulance in the water, and mixing of the air with the water, by the boats, caused the water to be cleaner, because tof the additional air mixed in the water.

The test is determine co levels in different Types of boats, ie fishing , I/o's, inboards etc. It is not to determine if Larry's test is right or wrong.
But for fun we are going to test it with and with out FAE at the end.


Last night we we tested the boat with ballast @ 10 mph and with out ballast at 10 mph. The ballast numbers will not be part of it, but we I will post the numbers on here after. FYI the numbers running with ballast on the back sun deck, well the alarm was on almost the whole time. I will get people the time weighted average once we get all the numbers in.
As well I just finish doing a fishing boat with a 20 h/p at 5 mph wow those numbers where very high.

[CMW]

is there anyway for your test to monitor at 65 -75 ft @ 21-23 mph with and without FAE? curious if FAE would limit CO while wakeboarding....

So just so I'm clear the premise of this study is measuring the levels of CO to those in the boat, on the sun pad, or on the transom while underway or stationary with the boat running. It looks like some here are trying to extrapolate your data as meaningful to people who are surfing behind the boat. As I read in your first post you are placing the equipment on the transom near the sun pad and measuring levels there, NOT where a typical surfer would be behind the boat by about 10-20ft. A study like that would be interesting but again just confirming that isn't the point of your research currently?

[Shockthis]

Correct, we are studding co at the back of the boat vs front of the boats at different speeds on different types of boats. This was more of a heads up for those sitting on the transome while someone is surfing, to let them know they are getting exposed to some serious co, or apperantly in a small fishing boat at 5mph. Maybe that is why I always hated fishing lol

[ddipert]

Was the outboard a 2 stroke or 4 stroke? It doesn't surprise me in the lease that an OB would give high CO readings at 5MPH. At that speed they the exhaust isn't going to flow any different than 5MPH behind an inboard.

Would suggest that you start to include the CO readings you are recording as it will help those following the thread. Even though you are referencing an alarm it does not suggest that there is a condition where CO poising exists. It simply is telling you that CO is present and the monitoring/ sampling device you are using is alarming at a preset and verified calibration level. For those reading this please understand the following:
The current OSHA Permissible Exposure Limit for CO is 50 parts per million in air (ppm) based on an 8 hour time weighted average.
This means that a person can be safely exposed to <50 ppm environment over and 8 hour period without the need for further engineering controls or respiratory protection.
In addition OSHA regulates and adopts exposure values from other sources like ACGIH TLVs.
The Short Term Exposure Limit (STEL) set by OSHA is currently at 200 ppm which is for exposures to CO for approximately 15 minutes or less.
The current Immediate Danger to Life and Health PEL is 1500 ppm CO. The IDLH suggest that CO enriched environment poses an immediate threat and the ability to succumb to death or other debilitating illness.
It would also be interesting to have you tell us what type of sampling device you are using to detect and quantify your research.

Paxdad, Great info! Answered a couple of my questions about exposure limits. Thanks!

Shockthis, I too am wondering which type of CO device you are using? Thanks for doing this field work.

Muskiedoo... You are spot on. Need to know the dose at the time to see how long (duration) your exposure can be.
