It can be difficult to manage samples in a laboratory. The management of samples can be complicated depending on their identity.
I.Biological samples refers to biological samples that were collected from biological sources both human (e.g. Blood, urine, saliva, and other non-human sources (e.g., fungal, bacterial or mammalian). .
II. Chemical samples refer to chemical samples that are made up of chemicals. These samples can be light-sensitive or sensitive to moisture, air, and light, or any combination thereof.
III. Samples that fit into more than one of the categories listed above, or samples that do not fit into any of the above categories.
Understanding how to manage these samples starts with identifying their categories. This will help you to understand the areas that are most important for you to work with them. This guide to sample management is divided according to the type of sample. If samples fall into multiple categories, it is important to review and follow all applicable procedures.

(a) A safety clearance from the institution for handling biological samples. When biological samples are contaminated, or could be contaminated with pathogens, individuals who work with them can be exposed to toxicants.
To limit the potential exposure of individuals to biological pathogens, many institutions have created required training. This training adds to the standard training for chemical sample workers. It includes instruction on how to properly dispose of biological samples and decontaminate surfaces before and afterwards.
II. Environmental Samples
(a) Security clearance from the institution to work with environmental samples. The potential for environmental samples (or those collected from multiple sites) to contain toxic chemicals, biological pathogens and other harmful substances is high. All individuals must receive institution-specific safety training in order to handle these samples.
(b) Collecting samples using equipment and methods that won’t introduce any exogenous contamination. As with biological samples, improper handling can lead to unwanted contamination. Environmental samples can also be affected by improper handling.
(c) Proper storage of samples. It is well-known that many compounds found in environmental samples have high sensitivity to light, temperature, and humidity. It is crucial to ensure that samples are stable and accurate during analysis.
III. Chemical Samples
(a) A safety clearance from the institution to work with chemical samples. Chemical samples may contain carcinogenic compounds, which can be inhaled, touched, or handled.
(b) Personal and engineering controls to reduce the safety risk for sample handlers. Chemical samples can be handled by individuals who have not been trained to handle them.
(c) Specialized procedures to handle sensitive samples. Chemical samples that are sensitive or affected by moisture and air need to be protected from these elements.
(a) Safety clearance. Radioactive materials are substances that emit or give off radioactivity. Heavy metals such as uranium emit radioactivity when it is degraded. Radioactivity is also produced by other heavy atoms like cesium and Iodine.
(b) Personal and engineering controls. Personal controls reduce radioactivity exposure of radioactive sample handlers. These controls include the use of specialized safety equipment such as safety goggles and safety suits while handling radioactive samples.
Conclusions and General Summary
It is a part of being a researcher. This is true for a wide range of disciplines and can be used to support a wider range of research projects. To properly handle such samples, you need to be familiar with their nature and trained to conduct experiments. You also need to know how to dispose of chemicals safely and reduce risks from the waste stream.
