How to Recognize and Avoid Them Working in a laboratory involves risks and dangers through a variety of hazardous substances or situations. The types of danger can be divided into four classes: chemical hazards, electrical hazards, biological hazards and physical hazards. To be prepared for the dangers and be able to prevent them, you must first…

TDI is produced through three main reactions: nitration, hydrogenation and phosgenation. The effluent from the third reactor is refined via distillation but not before remaining phosgene and hydrogen chloride are removed in a scrubber. As the reaction of phosgene with water is very slow, typically a caustic soda solution is chosen as a scrubbing agent…

Chemicals hazard symbols are not only found in the lab, they can also be found on some home products. Therefore it is necessary to know the meaning of each symbol. Some chemical hazard symbols are self-explanatory, some are not. The following overview covers common European hazard symbols and explains the dangers that they warn of.

Lean Laboratory aims to optimize productivity and efficiency, whilst eliminating any steps that do not add value. One aspect of Lean Laboratory is the systematic elimination of waste. The principle is to identify and then reduce or eliminate the time-wasting or unnecessary steps, in order to improve the efficiency and simplify the overall process. Lean…
