How it Works

CO-PRO is a quick and effective way to detect the presence of Carbon Monoxide (CO) in breathing air. If the air is contaminated by CO, the Capsule within the balloon will change color.

That's all there is to it.

Q: How many times can I use the CO-Pro?
A: It can be used multiple times or until carbon monoxide is detected.

Once the package is opened, the CO-Pro should not be exposed to atmospheric conditions longer than eight hours. Poor atmospheric conditions (carbon monoxide, moisture, etc..) can greatly decrease the sensor's ability to detect.

Q: At what ppm does the CO-Pro start to indicate?
A: The CO-Pro can indicate carbon monoxide as low as 5ppm.

Q: How long does it take for the CO-Pro to indicate carbon monoxide?
A: It all depends on the concentration level. The higher the concentration, the faster it will indicate.

Q: What is the shelf life of the CO-Pro?
A: Each package has an expiration date stamped on it. Approximately 2 years.

Dive Flag video Diving Equipment and Marketing Association (DEMA) and Diver's Alert Network (DAN) Release Public Service Announcement to Educate Boaters & Divers on Proper Use of a Dive Flag.     « - - click to view video

"Our goal in creating this important message is to remind divers and boaters that they share access to the same waters and thus need to adhere to safety precautions that will ensure an enjoyable experience for all," commented Tom Ingram, Executive Director of DEMA. "By increasing the awareness of the divers-down flag we hope to keep diving safe for everyone this summer."



The primary mission of the Ontario Underwater Council is to promote safety to the dive community. The OUC has implemented several initiatives to do this.

They are:

Aviva Barth Memorial Project (ABMP)

This project is to promote Boater Awareness of the two dive flags and what boaters should do when they see these flags.

On January 13, 2007, OUC kicked off its first initiative with the delivery of a Boater/Dive Flag Awareness flyer to four booths at the Toronto International Boat Show, in an effort to raise awareness of the dive flags within the boating communities.

Our message was embraced wholeheartedly and the offers to assist were quite encouraging. A number of people we talked to were also scuba divers and were very appreciative of the message being delivered.

You can see some of our initiatives here:

Diver access to this program is negotiated by the OUC.

Scuba Diver Safety Awareness Program (SDSAP)

This initiative is to reduce the number of fatalities which occur at Fathom Five National Underwater Marine Park. The program involves updated registration forms, shipwreck information and classification and other information.
