You won't get anyone answering "yes" on here (ooh I can feel the liability monsters biting as I speak) but your RA should ask the following questions:-

1) What are the gas(es) that may be present and does the detector detect them?
2) Does the detecting process cover the space adequately (i.e. are there dead spaces, corners etc that may still contain gases)?
3) Is there a policy on who must perform the test (from an insurer, etc)? The Confined Space Regulations simply require 'competence' but often companies impose stricter internal rules.


I would assume that for a sealed barge your primary concern is oxygen depletion from corrosion of the metal surfaces, in which case any detector with an O2 sensor would measure it - but if there are other issues such as residual chemicals, fumes from internal combustion engines, etc. you'll have to also sense for those. I presume the chemist that usually issues the certificate can explain what they'd test for.

There is a small flaw with your plan to lower the crowcon into the space. You need to be able to record the levels present. If you lower the crowcon in you will not be able to see the readings on screen. The crowcon will only alarm at set thresholds to meet the requirements of a suitable gas test you need to be able to record exact readings. There is a special pump tube you can get that fits onto the crowcon and then is lowered into the space, they are available in different lengths.

I Work offshore on an FPSO where we regularly have to enter balast tanks etc. drop me an email if you would like a copy of a gas testing procedure or indeed any other info on working in these spaces.
