Health risks in laboratories - HSE

The choice of control measures in laboratories is largely based on the hazard group of the biological agent that is being used (or that may be present). Biological agents are classified into one of four hazard groups from 1 (the lowest) to 4 (highest, eg Ebola) based on their ability to infect healthy adults. The classification is set out in the Approved List of Biological Agents. …

The Proteases in biological washing powder break Hb molecules into smaller molecules, which are not coloured and which dissolve in water and can be washed away. This makes the washing powder more effective than detergent alone, especially at lower temperatures. This save energy (no need to boil water), but if the temperature is too high, the enzyme will be denatured.
