3.1.8 wall wash test The procedure for washing selected areas, such as the interior bulkheads, tank bottoms, and sumps of cargo tanks, with designated reagent and, subsequently, testing the wash liquid for the presence of material that might contaminate cargo to be loaded. 3.1.9 wipe test The procedure of physically wiping any interior surface (bulkheads, steam coils, etc.) of the vessel’s tanks with absorbent white rags. This procedure is used to test the wiped surfaces for possible color contamination. 3.2 Acronyms and Abbreviations ACS American Chemical Society FOSFA Federation of Oils, Seeds and Fats Associations Ltd HDPE high-density polyethylene OBQ on board quantity SDS Safety Data Sheet 4 General Information The procedures in this guideline shall be performed only by properly trained, experienced personnel using appropriate equipment and methods. All procedures described and recommended in this publication shall be accomplished with strict adherence to the safety requirements that are specified in the International Safety Guide for Oil Tankers and Terminals (ISGOTT) or other specific requirements of vessel and terminal operators, and regulatory authorities. 5 Safety and Health Consideration 5.1 General Due consideration shall always be given to applicable safety and health procedures. Considerations should include—but are not limited to—possible electrostatic and other fire and explosion hazards, protection from potential dangers to personnel (e.g. various protective clothing and equipment requirements and work practices), and potential explosive, fire, toxic, and oxygen deficiency/enriched hazards associated with a cargo tank’s environment. The physical characteristics of the cargo and existing operating conditions should be evaluated carefully, and applicable international, federal, state, and local regulations should be strictly observed. Safety procedures designated by the employer, the vessel’s operator, and other concerned parties also shall be observed.
5.2 Physical Characteristics and Fire Considerations Information regarding particular materials should be obtained from the employer’s, manufacturer’s, or supplier’s Safety Data Sheet (SDS). Personnel who handle petroleum-related substances, as well as other chemical materials, should be familiar with their physical and chemical characteristics—including potential for fire, explosion, and reactivity—and with potential toxicity and health hazards and emergency procedures. Personnel should avoid potential sources of ignition and keep containers of materials closed, when not in use. 5.3 Special Safety Considerations—Entry into Confined Spaces It is the responsibility of vessel personnel to identify confined spaces and to ensure that established procedures for safe entry are followed. Inspectors shall consult the qualified person to determine whether entry into such confined spaces is permitted and shall be accompanied by a representative of the vessel at all times (ISGOTT). No one should enter a confined space unless an entry permit has been issued by a qualified person or certified marine chemist who has ascertained before entry that the tank atmosphere is in all respects safe for entry. Before issuing an entry permit, the qualified person shall at least ensure that: — the appropriate atmosphere checks have been carried out; — effective ventilation will be maintained continuously while personnel are in the confined space; — lifelines and harnesses are ready for immediate use; — approved and pre-tested breathing apparatus and resuscitation equipment are ready for use at the entry to the confined space; — personnel protective equipment shall be worn as appropriate for the task; — where possible, a separate means of access is available for use as an alternative means of escape in an emergency;
