OREANDA-NEWS. February 24, 2011. An emergency response drill was arranged at the plant under “fire” conventional complicated mode conditions. The drill was organized with a view of improving the personnel knowledge and prompt decision-taking and acting skills. Operative personnel of Krasnoyarsk CHP-2 and Crew No. 30 of the Federal Fire-Fighting Service participated in it.

According to the drill scenario, bearing seal failure of one of the turbo generators resulted in emission and subsequent ignition of hydrogen in the plant turbine shop. Heavy smoke formation occurred within the production premises which interfered with the personnel orientation in the situation. Amount of harmful substances emission within the production zone exceeded the allowed norms.

During the drill the personnel actions were well-adjusted and prompt. Upon receipt of information on the contingency situation the plant shift manager immediately notified the fire-fighting unit and the plant management, gave the command for the de-energized equipment switchover to stand-by supply and for increase of load on the other operating turbines. Simultaneously, fire fighting actions were taken. Members of the on-duty fire-fighting teams were provided with personal protective gear; the gates were opened for fire-engines ingress. One provided for chilling the machine hall girders and bearing structures using stationary and mobile fire-fighting monitors.

An important aspect of the drill was review of the personnel capability to prevent development of failure consequences and to eliminate them acting both independently and collectively. Supervision of the drill progress enabled the operational management of the plant to identify the need for organizational and technical measures aimed at improvement of the personnel work and equipment reliability enhancement.

The personnel was announced to have successfully coped with all the tasks set.
