EN 15154-2:2006 (E) 4 Introduction Plumbed-in eye wash units are designed and intended to be installed in close range of persons working in a potentially hazardous area. The main purpose of these devices i
16、s to immediately deliver flushing fluid in sufficient volume to flush the eyes following exposure to injurious substances or heat. With this accomplished the injured person can proceed to medical care. EN 15154-2:2006 (E) 5 1 Scope This document is a product specification, giving performance require
17、ments for emergency safety eye wash units connected to the water supply. It is applicable to plumbed-in eye wash units only. Requirements are given in respect of the performance, installation, adjustment and marking of the eye wash units, as well as installation, operation and maintenance instructio
18、ns to be given by the manufacturer. NOTE Attention is drawn to national regulations which may apply in respect of the installation and use of eye wash units. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only t
19、he edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 3864-1, Graphical symbols Safety colours and safety signs Part 1: Design principles for safety signs in workplaces and public areas 3 Terms and definitions For the
20、purposes of this document, the following terms and definitions apply. 3.1 emergency safety eye wash unit device specially designed and intended to deliver a flushing fluid to irrigate and flush the eyes and to sufficiently wash away contaminants or to dilute them, rendering them harmless 3.2 plumbed
21、-in emergency safety eye wash unit emergency safety eye wash unit that is permanently connected to a continuous water supply 4 Performance 4.1 Flow rate of water Plumbed-in eye wash units shall be designed to deliver a constant flow rate of minimum 6 l/min at a flow pressure to be specified by the m
22、anufacturer and to be measured where the eye wash unit is connected to the water system. Eye wash units shall be capable of delivering this supply for a minimum of 15 min. The velocity of the water shall be low enough to be non-injurious to the user. Nozzle(s) shall be protected from airborne contam
23、inants. Whatever means is used to afford such protection, its removal shall not require a separate motion by the user when activating the eye wash unit. 4.2 Jet height The jet of water supplied by the nozzle(s) shall spray at a minimum height of 100 mm and may spray at a maximum height of 300 mm bot
24、h measured from the nozzle centre, before tipping over or collapsing. EN 15154-2:2006 (E) 6 4.3 Water quality Potable water or water of a similar quality complying with European or national standards is required for eye wash units. Materials used in the construction of the eye wash unit shall not af
25、fect the water quality or contaminate the water supply. 4.4 Water temperature Information on water temperatures is given in Annex A (informative). NOTE Attention is drawn to national regulations which may apply in some European countries, e. g. in Sweden (see Bibliography 1 and 2). 5 Design requirem
26、ents for installation The outlet nozzle(s) on plumbed-in eye wash units mounted in fixed positions, shall be designed to be installed at a height of (1 000 200) mm above the level on which the user stands and at least 150 mm from the nearest wall or obstruction. 6 Valve For manual operation, the val
27、ve shall be opened in a single operation by turning or moving a valve actuator to maximum 90 or maximum 200 mm stroke. The maximum force for the operation shall be 100 N or the maximum torque 7 Nm. By using this force/torque, the valve shall be fully open within 1 s. For automatic operation, the val
28、ve shall be fully open within 1 s and shall be fail-safe at the open position if operated electrically. The valve shall not close automatically once it has been opened. The direction of operating the valve actuator shall be clearly visible and unmistakable. The valve actuator shall be large enough t
29、o be easily located and operated by the user even when wearing protective gloves. 7 Outlet Nozzle(s) The unit shall be designed to provide enough room to allow both eyelids to be held open while the eyes are in the water flushing stream. It shall only be possible to make adjustments with a tool to t
30、he direction of spray of the outlet nozzle(s). The outlet nozzle(s) shall be removable for maintenance but only by use of a tool. 8 Manufacturers information The manufacturer shall supply with the emergency eye wash unit information on installation, operation and maintenance as well as the method an
31、d frequency of routine testing. NOTE Attention is drawn to national regulations that might apply for installation, maintenance and routine testing. EN 15154-2:2006 (E) 7 9 Marking The eye wash unit shall be clearly and permanently marked showing requirements for minimum and maximum flow pressure and
32、 the maximum static pressure. Marking shall be performed by the manufacturer and shall show the name of the manufacturer and the model/article number. In addition, a safety sign in accordance with ISO 3864-1 displayable near the eye wash unit shall be supplied with each emergency eye wash unit. EN 1
33、5154-2:2006 (E) 8 Annex A (informative) A.1 Water temperature Continuous and timely irrigation of affected tissues for the recommended irrigation period are the principal factors in providing first aid treatment. Providing water at temperatures conducive to use for the recommended irrigation period
34、is considered an integral part of providing suitable facilities. Medical recommendations suggest water at tepid temperatures be delivered to affected chemically injured eyes. Temperatures in an excess of 37 C have proven to be harmful to the eyes and can enhance chemical interaction with the eyes an
35、d skin. While cold water temperatures provide immediate cooling after burns or chemical contact, prolonged exposure to cold water can result in the premature cessation of first aid treatment. Recent information indicates that a temperature of 15 C is suitable for the lower parameter for tepid water.
36、 A.2 Filter To avoid a build-up of water-borne contaminants, the water supply pipe can be fitted with a fine mesh filter.
