Introduction : In any laboratory dealing with biological experiments, hazards can occur mainly due to chemicals and biological materials. In the previous exercise you have done the activity of classifying hazardous chemicals and you also learnt the skill of handling such chemicals. In this exercise you will carry out the activities related to the disposal of biological materials after the experimental work with such materials is over. Disposal activities are related to microorganisms and dead animals. Since these materials cause contamination and infections very rapidly, more care is required in their disposal. Disposal of plant materials is comparatively simpler. Put all the used plant materials in a disposable bag, seal or tie the bag and put it in the waste collecting bins.
