Abstract: The present invention relates to a method for producing polyurethane foams by reacting an isocyanate component with an isocyanate-reactive component comprising at least one polyethercarbonate polyol, the reaction taking place in the presence of a component K selected from one or more compounds from the group consisting of K1 esters of mono- or polybasic carboxylic acids whose (first) dissociation has a pKa of 0.5 to 4.0, K2 mono-, di- and polysulfonates of mono- and polyfunctional alcohols, and K3 one or more compounds from the group consisting of K 3.1 esters of phosphoric acid, phosphonic acid, phosphorous acid, phosphinic acid, phosphonous acid and phosphinous acid, these esters each containing no P—OH group, K3.

Abstract: A computer-implemented method of performing a risk analysis for a project is described. The computer-implemented method includes, generating, in a hierarchical database, a plurality of area checklists in the form of documents, wherein each area checklist has at least one input field into which data is input. Next, the data from the hierarchical database is exported to a relational database. After completion of the exporting step, the relational database is accessed, and the risk analysis is performed on the data that has been exported into the relational database. The risk analysis results of the project are then outputted.
