- (b) Each facility must have a means, which may be the communications system itself, that enables a person on board a vessel or on the facility to effectively indicate the desire to use the means of communication required by [paragraph (a)](#a) of this section.
- (c) The means required by [paragraph (a)](#a) of this section must be usable and effective in all phases of the transfer operation and all conditions of weather at the facility.
- (d) A facility may use the system in [§ 154.550(a)(2)](/cfr/33/154.550.md?p=a-2) to meet the requirement of [paragraph (a)](#a) of this section.
- (e) Portable radio devices used to comply with [paragraph (a)](#a) of this section during the transfer of flammable or combustible liquids must be marked as intrinsically safe by the manufacturer of the device and certified as intrinsically safe by a national testing laboratory or other certification organization approved by the Commandant as defined in [46 CFR 111.105-11](/cfr/46/111.105-11.md).
