Management of acute exposure to toxic gases in the oil & gas industry -a practical approach

The objective of this work is to present the key elements in the design of emergency management and response plans in scenarios where there has been loss of containment of chemical agents of acute effect focused in the protection of not routinely exposed in a determined occupational environment. To this purpose, a validation of the current criteria for the management of accidental releases is carried out, taking into account hypothetical risk scenarios. The essential elements of the emergency management system are stated, from a systemic perspective and the corresponding risk control actions; recommendations for their implementation are showed, taking as prototype hydrogen sulfide, a highly toxic gas. Non controlled emissions of toxic gases of acute effect from an occupational standpoint represents a priority because of their human and financial high toll. Design and implementation of an appropriate emergency plan for uncontrollable emissions of toxics chemical agents must be addressed.
