                                        In addition to fire hose reels for water extinguishing of Class A type fires
                                        involving combustible materials, such as wood, paper and fabrics, all
                                        tankers are provided with a range of portable fire extinguishers. Table 8.1
                                        provides an overview of the types of extinguisher likely to be found on
                                        board a tanker and their uses. Class D type fires are included mainly for
                                        completeness. (See Section 5.2 for information on the Classification of
                                        Fires.)

                                   This Section provides operational guidance on the use of the gas measuring
                                   instruments described in Section 2.4.

                                   The safe management of operations on board tankers is often dependent upon
                                   the crew’s ability to determine the composition of the ambient atmosphere or
                                   the atmosphere in an enclosed space.

                                   Tanker crews need to measure the oxygen, hydrocarbon and toxic gas
                                   concentrations in an atmosphere. This will enable them to detect the presence
                                   of any explosive mixtures, toxic vapours or oxygen deficiency that may present
                                   a risk of explosion or hazard to personnel.


                                   On tankers fitted with an inert gas system, there is the additional need to
                                   measure the oxygen content of inert gas as part of the safe management of
                                   cargo tank atmospheres.
