<p>The invention relates to a hydrant security device for use with a hydrant (1 figure 1) having an outlet 3 and an actuator 4 for operating a valve to control the flow of liquid from the outlet 3. The security device comprises a first anti-tamper cap 6 which is engageable over the actuator 4 so as to prevent access. The first cap 6 has an arm 6b extending therefrom which has an opening (6c figure 3c) sized and positioned to engage over the outlet 3 with the outlet protruding through the opening (6c figure 3c) when the first cap 6 is located on the actuator 4. A second outlet cap 7 is engageable over the outlet 3 and arm 6b so as to prevent access to the actuator 4 and prevents removal of the opening (6c figure 3c) from the around the outlet 3. The second outlet cap 7 is then securable to the outlet 3, over the arm of the first cap 6, thereby preventing unauthorised access to both the outlet and the actuator. Later embodiment relates to a method of securing a hydrant using said security device.</p> |
