  1. 1

    Administrative controls

    This type of control involves changing work practices and policies. A question to consider:

    • Can patients with TB be isolated from other patients (e.g., in a negative-pressure isolation room)?
  2. 2

    Personal protective equipment (PPE)

    This is the least effective type of control. When used, there must always be at least one other control in place as well. Some questions to consider:

    • Are workers using respirators as required by the exposure control plan?
    • Are workers using protective clothing, gloves and goggles as required by the exposure control plan?
