I would have a confirmation to the following:

On board my LPG/LNG ships, at least the following type/number of gas detector instruments should be be available on board:

A) Two portable sets of gas detection equipment suitable for the products carried, B) Two instruments suitable for the testing of flammable vapors in an oxygen detective atmosphere, C) Two Oxygen detectors for personal use; D) Two gas detectors for personal use, E) Two H2s monitoring instruments for personal use, F) Two toxic gas detectors.

Are there any other instruments that i may forget ?

Answer:

G) There is a requirement to carry two instruments for checking Carbon Monoxide

Requirements in items C, D, E, G may be satisfied by the single multi-gas detector which measures O2, HC %LEL, H2S, CO. Additionally, more than two may be required. My current VLGC carries 3 multi-gas detectors for personal use.

H) Portable flammable vapors (%LEL) detectors in inerted atmosphere

There is a requirement to carry instruments capable of remote measuring gas content by extended tube:

I) Oxygen analyzer, 2 pcs

J) Hydro Carbon measuring meter, 2 pcs

K) Instrument for checking Carbon Monoxide

Requirements in A, B, H, I, J, K may be satisfied by the single portable multi gas detector, “tankscope”. In this case, two of them should be carried on board.

Toxic gas detectors should be carried by vessels with toxic cargo. The rest should carry instruments, capable of detecting Benzene.

Summary (real life example):

My current VLGC carries:

1) 3 multi-gas detectors for personal use

personal multi gas detector

2) 2 portable multi-gas detectors capable of remote measuring portable remote multi-gas detector

3) set of Draeger tubes for measuring Benzene content (during bunkering)
