Thread Content

145. There are sudden reactions, but no measures or training to deal with them. 146. The amount of material fed in or its ratio is changed arbitrarily. 147. Process improvements or new processes are implemented without conducting safety assessments. 148. Process changes are not subjected to thorough review and approval. 149. The process operates within the explosion limits of flammable gases. 150. Open-air operations are used when highly toxic materials are handled. 151. No process operation procedures are established for pilot production. 152. No data on the physical properties of the materials used nor guidelines for their safe handling are available. 153. The heat generated when the materials used decompose is not carefully calculated. 154. There is a potential risk of dust explosions. 155. When certain raw materials cannot be supplied in time, there is a danger associated with storing the materials in the reactor. 156. Raw materials or intermediates may catch fire, polymerize, or decompose during storage. 157. Various process parameters (such as temperature and pressure) are close to dangerous levels. 158. In case of abnormal conditions, there are no measures to quickly remove the reactants. 159. There are no measures to prevent or stop rapid reactions
