One of the exhibits at the 2002 Valve World Conference Safety is CEF Safety Systems BV new stainless steel version of its V-Safe valve cover. This highly visible device secures the regulation of liquids and gases by enclosing wheel-operated valves, protecting against inadvertent or unauthorised operation and ensuring that potentially hazardous maintenance can be carried out safely. Available with either a yellow polyester coat or a high polish, natural stainless steel finish, the tamper proof cover comes in four different sizes to fit wheel diameters from 100mm up to 350mm. It consists of two hinged half-moons with multi-hole padlocking facility. Perforations in the edges reduce weight and prevent the build up of fugitive emissions. When locked, the cover completely encloses a valve hand-wheel, making operation impossible, ensuring that authorised personnel can only carry out essential valve operation. When used as a maintenance lockout, up to seven padlocks can be fitted at one time and valve operation can only be restored once all personnel have completed their work and removed their padlocks.
