These fluids fall under category HFDR of ISO 6743-41.This document is intended to: assist the power equipment operator to maintain the fluid
33、 in a condition that will ensure the safe and reliable operation of the turbine while maximizing fluid life; recommend procedures for examining consignments of new fluid and monitoring the fluid in use; provide information on the safe handling, storage and disposal of the fluid; offer background inf

37、vailable at http:/www.electropedia.org/4 Description of triaryl phosphate ester fluidsTriaryl phosphates are complex mixtures of products produced from the reaction of phosphorus oxychloride with substituted phenols, for example xylenol or tertiarybutylphenol, and have been used as fire-resistant fl
38、uids in power generation applications for over 55 years. While the early fluids were INTERNATIONAL STANDARD ISO 11365:2017(E) ISO 2017 All rights reserved 1BS ISO 11365:2017ISO 11365:2017(E)neurotoxic as a result of the presence of tri-o-cresyl phosphate, the products in commercial use for about the
39、 past 35 years have been free from this component and have very low levels of neurotoxicity. Modern phosphate esters are manufactured to meet the stringent health and safety requirements of CEN/TR 144892. However, such requirements are subject to change and the fluid manufacturers should be contacte
40、d for the latest information. As with all chemicals, triaryl phosphates should be handled responsibly. The health and safety recommendations given in this document are intended to minimize exposure and to provide a margin of safety for workers handling these fluids.Triaryl phosphate ester fluids nor
41、mally have good resistance to oxidation, moderate to good air release and low foaming properties. However, they are sensitive to hydrolysis. These properties will, of course, slowly deteriorate during the life of the fluid. While some degradation can be tolerated without adverse effects on system pe
42、rformance, good monitoring procedures are necessary to determine when the properties have changed sufficiently to require action.ISO 100503is the standard for new triaryl phosphate ester hydraulic fluids when used in power generation applications.For further information on the composition and techni
43、cal performance of these fluids, the relevant technical literature available from the fluid manufacturers or suppliers should be consulted.5 Health and safety precautions5.1 Fluid handlingTriaryl phosphate ester fluids have extremely low vapour pressures and excellent stability, and under normal ope
44、rating conditions give off no harmful vapours. There have been no reports of toxic effects through continued exposure, where sensible handling precautions have been taken. However, when handling phosphate esters all personnel should be aware of the nature of the material they are handling and consid
45、er the recommendations set out below. Accidental swallowing of the fluid or inhalation of vapours at elevated temperatures, which are the main potential sources of entry into the body, can be harmful and should be avoided. In event of ingestion, medical attention should be sought immediately. Goggle
46、s should be worn at all times when the fluid is being handled or when working on hydraulic control or other systems containing the fluid. Eye splashes may cause severe irritation. If any fluid gets into the eyes, they should be irrigated with water as soon as possible and medical attention sought. W
47、hile the fluid is being handled, eating, drinking and smoking should be prohibited to prevent contamination of the lips and mouth. After handling the fluid, and before eating, drinking or smoking, the hands shall be thoroughly washed. Exposure to the skin normally represents minimal hazard and stand
48、ard sanitary practices will prevent any adverse health effects. No ill effects have been reported from short-term skin exposure. However, continuous exposure to degraded fluid, which is acidic, should be avoided. This can be achieved using suitable impermeable protective gloves or barrier creams. Pa
49、rticular attention should be paid to the thorough cleaning of the skin and removal of any soiled clothing if extensive and prolonged contact with the fluid occurs. If the fluid leaks on to hot pipework, white fumes may be emitted. If these are inhaled, they can cause irritation of the throat and lungs. Therefore, when working in an environment where fumes are being emitted, breathing apparatus should be worn.If required, further handling and safety information can be obtained from the fluid ma
