Alberta Boilers Safety Association (ABSA) Practice Test

All maintenance work done on portable fire extinguishers is required to be:

1. Completed on all extinguishers in the plant at the same time

2. Performed at the worksite in case they are required for emergency service

3. Contracted out to a certified service company

4. Supervised by national fire protection Association employee

The correct answer is: Contracted out to a certified service company

Maintenance work on portable fire extinguishers must be performed by a qualified and certified service company to ensure compliance with safety regulations and standards. This requirement is in place to guarantee that all maintenance activities are conducted by individuals who have the necessary training, expertise, and technical knowledge to inspect, test, and service the extinguishers properly. Certified service companies are familiar with the latest codes and practices, which helps to ensure that the extinguishers are functioning correctly and are safe for use in an emergency. Regular maintenance can include checking for mechanical parts, ensuring the extinguishers are fully charged, conducting proper inspections, and replacing any faulty components. The other options do not provide the same level of assurance regarding the quality and safety of maintenance work. For instance, performing maintenance all at the same time does not account for individual extinguisher condition or availability. Conducting maintenance at the worksite may not allow for proper testing or repair. Supervision by employees from the National Fire Protection Association is not a standard requirement and does not imply the hands-on expertise necessary for maintenance tasks. Thus, contracting the work to a certified service company ensures adherence to safety standards and regulations.
