Certain types of leak from pressurised piping (including valves) may be effectively contained by on-line sealing methods involving the use of elastomeric compounds. These (essentially temporary) repair methods were originally developed for application to leaking steam and condensate systems. However with additional safety precautions, they may be applied to process piping systems containing flammable, corrosive and/or toxic fluids. EEMUA 199 gives guidance on the limits of application of the technique, the factors to be considered when evaluating the feasibility of its use, the preparation and execution of the procedure and the type of risk assessment required.
