Carbon monoxide exposure and poisoning
High risk occupations

Occupations at high risk of carbon monoxide exposure and poisoning include:

  • Diesel engine operators

  • Forklift operators

  • Mechanics

  • Welders

  • Firefighters

  • Toll booth tunnel attendants are at especially high risk of chronic carbon monoxide exposure

  • Longshoremen / stevedores

  • Marine terminal workers

  • Customs inspectors

  • Police officers

  • Taxi drivers

  • Industrial painters

  • Traffic control workers

  • Some gas company workers are at especially high risk of carbon monoxide exposure

  • Tunnel workers

  • Warehouse workers

  • Sewer workers

  • Miners

  • Industry workers in specialized manufacturing or production processes

  • Workers in enclosed and semi-enclosed areas have an increased risk of carbon monoxide exposure

  • Hair dressers that worked in the 1970's and 80's when methylene chloride was used as a propellent for hair spray

Any of these occupations can easily be exposed to higher than normal levels of carbon monoxide in the work environment.

Carbon monoxide exposure results in higher than normal levels of carbon monoxide entering the body/blood stream and unsafe levels staying in the body/blood stream.

High co long term 50-250 co
Mr green
we have just had a co meter put in a room where gas is controller for furnaces, the reading shows co goes upto 250 ppm have may have been in the room 3 or more hours per day 7 days a week, what damage will we have had done, this may have been upto 10 years everyday.

There are several things to consider when answering to your question:
1) Just because a CO reading shows xxx ppm at one point in TIME does not mean that the CO has consistently been at that level. It can vary very significantly over time.

2) Just because a CO reading shows xxx ppm at one point in a BUILDING OR AREA does not mean the CO is at that level in all areas. It can vary quite significantly, even in the same room.

3) Being exposed to CO is definitely NOT good however, people respond very differently to the same level of exposure and have very different health effects from it.

4) Question: have you been experiencing symptoms of low level exposure?

5) Carbon monoxide poisoning places a strain on cells throughout the body. It can injure and damage them affecting the functioning of cells and the organs/systems they are part of. So it is possible additional health effects show up down the road but almost always the connection back to CO poisoning as the underlying cause is missed.
6) Recommendations:
a) Learn more about it. Our website is a good resource, the best one we know of for CO survivors.
b) Make changes to your lifestyle to support and strengthen your body.

Please let us know how you are doing. We care.

I've been working at a place for over 3 years, we just installed CO alarm about a month ago. Carbon monoxide levels showed 50-100 ppm.

My question is: how will this affect my health in future and for how long?

Iam from UK
I was exposed to methylene chloride at work - it is well reported in the medical papers to break down to CO in the body, but was missed by doctors on numerous visits. A fellow employee who was exposed the prior week (whilst I was on holiday) had immediate heart related hospital admission. I developed mental health issues that were missed and mis-diagnosed.

Since I recovered from the acute effects (a 10 month recovery), I have been researching the health effects as my initial report of the poisoning was met with great skepticism. I have also had an MRI scan which shows many features that match medical journal reports.

Keep up the excellent work.
