What's the name of the test equipment?
What qualifications required to operate same?
In 1960-65 I couldn't see through the fog generated by ripsaws ripping it off all steam pipes, do these new regs mean I'm on borrowed time?
In my experience "Air Sampling" in a space is done with a specialized air pump with a very fine filter on it's suction. After the pump is run for up to an hour in a given area the filter is removed, placed in a sterile bag and sent to a lab for analysis.
The testing, location & condition recording of asbestos on the ships I was on since the requirement came into effect, was done by a company from Ontario certified by the province to do the required testing. Regular testing and inspections were done an annual basis and reports were retained on board and were reviewed by Class on behalf of Transport Canada. The particular Company that does the testing that I was dealing with, is also certified to and has all the specialized equipment and training to manage the removal and or encapsulation of Asbestos.
There doesn't seem to be any kind of guidance in the current or amended reg's as to where and when testing should be carried out that I can see. Leaving it up to the company owning the ship and the testing company to set the parameters for testing with respect to where and when testing is to be carried out. Allowing testing to be done when everything is shut down reducing the risk of atmospheric contamination by asbestos caused by vibration and other factors, caused a real problem for me a few years ago.
After reporting to the vessel's manager that there was an issue with Asbestos precipitation from the block insulation around the exhaust of the Main Engine due to vibration while working in ice. The Manager then ordered an "Air" test to be carried out at various points around the ship, while in port with the absolute minimum of equipment running. In effect stipulating conditions that would give more desirable results. The manager, with a extremely sharp eye on the "Budget", used the report, based on "Air" sampling results with little or no asbestos fibers in the local atmosphere to refute my concerns and as a justification to use what more commonly know as the "Handyman's Secret Weapon" here in Canada or Duct Tape to patch the leaks in the canvas cover over the insulation. This despite vibration was causing Asbestos to quite literally fall like snow out of every expansion joint and support bracket in the exhaust onto the deck in the engine room and being sucked into the engine turbo filters. It took a lot of fighting and arguing that almost cost people their jobs, on mine and few others parts, to get a serious health issue rectified but eventually the original exhaust insulation was properly sealed and encapsulated.
Finally Yes Merlyn, you like the rest of us are on borrowed time. If the Asbestos don't get us Cigarettes, Cigars and now Marijuana or Booze just might!
