The health hazards involved when dealing with heavy oils and lube oils
⇐ ПредыдущаяСтр 3 из 3
As a result of the deterioration in quality of fuel oils, the danger has arisen that the heavy oils used on board contain greater amounts of substances injurious to health. These include: - Polycyclic aromatic hydrocarbons - Lead compounds - Chemical residues An increased amount of polycyclic aromatic hydrocarbons is also present in used lube oils (waste oils). The health hazards for the engine room staff depend to a large - extent on the concentrations of the dangerous substances - the ambient air (inhalation of oil vapours/oil mist) - the intensity and duration of the contact with the skin or mucous membrane.

The following is compulsory for safe operation:
1. Never start up a separator before the bowl is completely assembled, and all fastenings securely tightened. 2. Never discharge a vibrating separator. Always stop with the emergency stop button. 3. Never begin to disassemble a separator before it has come to a complete standstill. 4. Always set the discharge intervals according to instructions in the instruction book. 5. Never ignore alarms. Always eliminate the cause before resuming operation. 6. Never use the separator for other liquids than those specified by Alfa Laval. 7. Never operate a separator with a different power supply frequency than stated on the machine plate. 8. Ensure that enough conditioning water is added before discharge, as described in the instruction book. 9. Clean the operating system regularly to avoid sludge discharge malfunction. 10. Ensure that personnel are fully trained and competent in installation, operation, maintenance, and emergency procedures. 11. Use only Alfa Laval genuine spare parts and the special tools supplied.

Maintenance Entrapment hazard Make sure that rotating parts have come to a complete standstill before starting any dismantling work. The rotation indicator lamp, where applicable, must be off. Disintegration hazards Inspect regularly for erosion damage. Inspect frequently if the process liquid is erosive. Disintegration hazard Pits and spots forming a line may indicate cracks beneath the surface. All forms of cracks are a potential danger and are totally unacceptable. Replace the part if corrosion can be suspected of affecting its strength or function. Disintegration hazard All forms of cracks are potentially dangerous as they reduce the strength and functional ability of components. Always replace a part if cracks are present. Disintegration hazard The assembly mark on the bowl hood must never pass the mark on the bowl body by more than 25°.
