What should be done to portable vacuum cleaners and shop-type vacuums not equipped with HEPA filtration?

Using portable vacuum cleaners and shop-type vacuums that are not equipped with HEPA filtration requires special consideration due to their potential to recirculate harmful particles into the air. Exhausting these vacuums out of the building is the most appropriate action, as it helps to ensure that any allergens, dust, or contaminants picked up during cleaning do not remain in the indoor environment. This is particularly crucial in trauma and crime scene cleanup situations, where the vacuum may siphon up biohazards that pose health risks.

By directing the exhaust outside, the harmful particles and contaminants are disposed of safely, reducing the chance of airborne exposure to individuals in the vicinity. This practice emphasizes the need for maintaining a safe and clear air environment when dealing with hazardous materials, making it an essential protocol in trauma and crime scene cleanup scenarios.
