Final answer:
Special masks, such as N95 or HEPA masks, may be required in situations where there is a risk of contact with respiratory droplets or airborne particles, as part of Contact, Airborne, and Droplet Precautions. HEPA filters are commonly used in hospitals to prevent contamination and remove airborne microbes.
Step-by-step explanation:
When it comes to preventing the spread of airborne microbes, special masks may be required. In situations where there is a risk of contact with respiratory droplets or airborne particles, precautions such as Contact, Airborne, and Droplet Precautions are used. These precautions may require the use of a special mask, such as an N95 or HEPA mask. HEPA filters, which are also commonly used in hospitals and surgical suites, are designed to remove airborne microbes and prevent contamination.
