17、trolled Copy, (c) BSI 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 is to immediately deliver flushing fluid in sufficient volume to flush the
18、 eyes following exposure to injurious substances or heat. With this accomplished the injured person can proceed to medical care.

19、s document is a product specification, giving performance requirements 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 uni
20、ts, as well as installation, operation and maintenance instructions 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 f
21、or the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

22、s in workplaces and public areas 3 Terms and definitions For the 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 co
23、ntaminants or to dilute them, rendering them harmless 3.2 plumbed-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 ra
24、te of minimum 6 l/min at a flow pressure to be specified by the manufacturer 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-injurio
25、us to the user. Nozzle(s) shall be protected from airborne contaminants. 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
26、 height of 100 mm and may spray at a maximum height of 300 mm both measured from the nozzle centre, before tipping over or collapsing.

27、ater 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 affect the water quality or contaminate the water supply. 4.4 Water temperature Information on wate
28、r 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 requirements for installation The outlet nozzle(s) on plumbed-in eye wash units mounted in fixed position
29、s, 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 valve shall be opened in a single operation by turning or moving a valve actuator to maximum 90 or m
30、aximum 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 valve shall be fully open within 1 s and shall be fail-safe at the open position if operated electri
31、cally. 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 to be easily located and operated by the user even when wearing protective gloves. 7 Outlet Nozzle
32、(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 the direction of spray of the outlet nozzle(s). The outlet nozzle(s) shall be removable for mainte
33、nance 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 and frequency of routine testing. NOTE Attention is drawn to national regulations that might apply
34、for installation, maintenance and routine testing.

35、for minimum and maximum flow pressure and 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 supplie
36、d with each emergency eye wash unit.

37、e recommended irrigation period are the principal factors in providing first aid treatment. Providing water at temperatures conducive to use for the recommended irrigation period is considered an integral part of providing suitable facilities. Medical recommendations suggest water at tepid temperatu
38、res 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 and skin. While cold water temperatures provide immediate cooling after burns or chemical contact, prolonged exposure to co
39、ld 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. A.2 Filter To avoid a build-up of water-borne contaminants, the water supply pipe can be fitted with a fine mesh filter.
