Final answer:
Gross decontamination's advantage is the immediate reduction of contaminants in the field. It effectively reduces the risk of secondary contamination but may require follow-up processes for complete cleansing.
Step-by-step explanation:
The advantage of gross decontamination is that it is conducted in the field, so the reduction of contaminants is immediate. One of the main purposes of decontamination is to eliminate or reduce the presence of harmful substances, which can include biological contaminants such as bacteria and viruses, as well as chemical substances. In the case of gross decontamination, the immediate reduction of contaminants is crucial to minimize further exposure and spread of these harmful substances.
Gross decontamination works effectively in the field by removing a large quantity of contaminants from people, equipment, or environments, thereby significantly reducing the risk of secondary contamination. However, it is important to note that gross decontamination may not remove all contaminants and, in most cases, will require follow-up decontamination processes to ensure a thorough cleansing.
