LungsBreathing is the most common way for contaminants to enter the human body. When working in the lab, you should be aware of aerosol-producing procedures such as:
  1. Accidental spills
  2. Centrifugation
  3. Pipetting
  4. Weighing
  5. Injections using syringes and needles
  6. Removing caps and stoppers
  7. Clean-up procedures, dry sweeping
which introduce contaminants to the air and make them easier to inhale.

Mechanisms to control exposures can be achieved through safe work practices, administrative controls (i.e. substitution of a less hazardous chemical), and personal protective equipment.
