Final answer:
Firefighters or fire safety professionals are responsible for servicing and testing fire extinguishers on a regular basis to ensure they are in proper working condition.
Step-by-step explanation:
In terms of servicing and testing fire extinguishers, this responsibility typically falls under the domain of firefighters or fire safety professionals. They are trained in the maintenance, inspection, and testing of fire extinguishers to ensure they are in proper working condition.
Firefighters and fire safety professionals regularly inspect fire extinguishers to check for any signs of damage, corrosion, or expired components. They also conduct routine testing to verify that the extinguishers are working effectively. If any issues are identified during these inspections or tests, the necessary steps are taken to repair or replace the fire extinguisher.
It is important to note that while fire extinguishers are typically serviced and tested by firefighters or fire safety professionals, it is the responsibility of individuals and organizations to ensure that their fire extinguishers are properly maintained and regularly inspected.
