Final answer:
Yes, air monitoring is necessary when working in a confined space to ensure the air is free from harmful pollutants and has safe oxygen levels. Adequate ventilation, continuous monitoring, and the use of protective suits with their own air supply are crucial precautions.
Step-by-step explanation:
When performing work within a confined space, it is indeed necessary to conduct air monitoring. This is because the air in such environments can potentially contain harmful pollutants or be deficient in oxygen, posing serious health risks. Before entry, it's important to assess the air for toxic gases, flammable or explosive compounds, and to ensure that oxygen levels are safe. Continuous air monitoring may also be required, depending on the nature of the space and the work being done.
Examples of guidelines for maintaining safety in confined spaces include always ventilating the area adequately and following the manufacturer's instructions for tools and equipment to avoid the buildup of pollutants. Using protection like a suit with its own air supply, as seen in BSL-4 laboratories, is another precaution. To further mitigate risks, suggestions like using less toxic chemicals, having proper ventilation, and owning detectors for radon and carbon monoxide can be applied both in confined spaces and in homes to improve indoor air quality.
