Now we are going demonstrate how to use a gas monitor. Here we are in our working environment, and the very first thing I can do is just check around the gaps of this man-hole cover. Because if there is any leakage, then the gas monitor will pick it up and it would then detect and go off. It could be that if you have got a hatchway, you open the hatchway up a little bit and do the test again in that little gap. Once that has been completed, that is the initial test. Now I am going to open up the hatchway and do another test. To confirm, because we are now working height, got my harness on, got my full protection in place so I know that I am able to stay within this various zone that obviously is dangerous. Gas monitor, we are now going to lower it in, and we are going to do a three-point test. The top, and hold it there for about 10 seconds or so, and then we move down to the middle for approximately another 10 seconds, and then right to the very bottom. This is due to the fact that many gases are different weights. And therefore to make sure that we get the right test, give it a time in each of those levels. And the same on the way back up again. To the middle for a few seconds, all the way back to the top. And next I read the readings and I will start to scroll through in case any peak readings or anything that might be in there.

And that is how we test our confined space. Now the safety attendant, he is going to make a note of our readings. Very important we document the findings, and as and when we conduct testing, we continue to document those findings, particularly as part of both of the permit to work, and generally many would like to make sure that we are monitoring and proving that we are monitoring on a regular basis, and to confirm that the safety attendant also has a full protection in place. Because on this occasion we are going to be working away from our point of entry, each of the entrants, myself and Jim, we have got personal gas monitors on. As I go down into the confined space, he will monitor. Once I have detached, we send back the man-riding winch, he will attach and enter.

Now I am at the bottom of the confined space. I will be detaching, ready for the next person to come down and join me as we leave this point of entry and proceed inside the confined space. My personal gas monitor is on, so I am now able to leave the point of entry. It will continue to monitor as I continue to do the job.
