Precautions against ships communication equipments - Chemical tankers safety guideline

Chemical tankers's radio transmission equipment: During medium and high frequency radio transmissions significant energy is radiated, which can create a danger of incendive sparking by inducing an electrical potential in unearthed steelwork. The use of medium or high frequency main radio transmission equipment should therefore be prohibited in port and during ship to ship cargo transfers. If it is necessary to operate the ship's radio in port for maintenance the agreement of the terminal and port authorities should be sought.

Low energy transmissions of one watt or less, such as are used for VHF/UHF radios or satellite equipment, are not considered a hazard. The repositioning of satellite aerials, however, may involve the running of non-approved drive motors within a shore hazardous zone, and consultation between the tanker and the terminal is advisable before the satellite terminal is operated.

Ships crew to aware the importance of restricting use of mobile phone in hazardous areas / outside accommodation spaces. Master to identify hazardous areas, discuss with safety officer and crew and display warning sign to alert all crew members on the restriction of use of Mobile phones. As agreed in Ship / Shore safety checklist duty officer should perform repetitive checks to ensure compliance towards same. Also mobile phones should never be used during working period especially when involved in watch keeping which may distract the person from his job task due to lack of concentration.

Personal radio items

Personal equipment such as mobile telephones and radio pagers, if switched on, can be activated remotely and a hazard can be generated by the alerting or calling mechanism and, in the case of mobile telephones, by the natural response to answer the call. In view of the widespread use of such equipment, appropriate measures should be taken to prevent its use within the cargo area. Visitors should be informed that such items should only be switched on in a safe area, such as within the ship's accommodation.

Small battery powered personal items such as watches and hearing aids are not significant ignition sources when correctly used. However, portable domestic radios, electronic calculators, tape recorders, cameras and other non-approved battery powered equipment should not be used in the cargo area or wherever flammable vapour may be encountered. When in port, local regulations may prohibit the use of any portable electrical equipement.

where use of mobile phones, pagers, cameras and other non-intrinsically safe electronic equipment is strictly prohibited in dangerous areas on tankers and other vessels carrying dangerous goods. In addition it requires Master to identify the areas inside the accommodation including hazardous areas where a warning sign is to be posted regarding restriction of use of Mobile phones.
