Concepts and their limits
Technicians keep certification evidence at the business through three years after ceasing technician operations; EPA does not generally require carrying the card at every service call. For disposal of appliances normally containing more than 5 andless than 50 lb, record company name, location, date and refrigerant type, monthly amounts recovered, and transfers for reclamation or destruction; keep records for three years. A leak inspection locates leaks; an initial verification checks repair success; follow-up verifies after normal operating conditions subject to the stated professional-judgment exception. Changes to the Section 608 leak-repair provision for substitute refrigerants did not remove other requirements such as certification, recovery, sales restrictions and reclamation.
Worked decisions
A certified technician is asked where EPA requires certification evidence to be kept. Which answer fits? The decision is At the place of business. Technicians keep certification evidence at the business through three years after ceasing technician operations; EPA does not generally require carrying the card at every service call. A technician disposes of a mid-sized stationary appliance. Which record directly identifies that recovery event? The decision is Company name, location, date and refrigerant type. For disposal of appliances normally containing more than 5 andless than 50 lb, record company name, location, date and refrigerant type, monthly amounts recovered, and transfers for reclamation or destruction; keep records for three years. An instrument test only shows that a sealed system loses pressure, without locating a leak. What is the limitation? The decision is It does not by itself satisfy a leak inspection that locates leaks. A leak inspection locates leaks; an initial verification checks repair success; follow-up verifies after normal operating conditions subject to the stated professional-judgment exception. A manager reads the 2020 change to substitute-refrigerant leak-repair requirements and concludes HFC service needs no technician certification. What is the error? The decision is The change did not remove the certification requirement. Changes to the Section 608 leak-repair provision for substitute refrigerants did not remove other requirements such as certification, recovery, sales restrictions and reclamation.
Contrasts that change the decision
A technician stops operating in the trade. How long must the certification copy remain after that point? Here the supported answer is Three years. Technicians keep certification evidence at the business through three years after ceasing technician operations; EPA does not generally require carrying the card at every service call. Several mid-sized appliances are disposed of in a month. Which quantity should be tracked by refrigerant type? Here the supported answer is The amount recovered during the month. For disposal of appliances normally containing more than 5 andless than 50 lb, record company name, location, date and refrigerant type, monthly amounts recovered, and transfers for reclamation or destruction; keep records for three years. After repairing an identified leak, a technician tests the repair before recharge. Which record category fits? Here the supported answer is Initial verification. A leak inspection locates leaks; an initial verification checks repair success; follow-up verifies after normal operating conditions subject to the stated professional-judgment exception. An HFC appliance is opened for service. Does the Section 608 leak-repair change by itself eliminate applicable evacuation requirements? Here the supported answer is No; evacuation requirements remain distinct. Changes to the Section 608 leak-repair provision for substitute refrigerants did not remove other requirements such as certification, recovery, sales restrictions and reclamation.
Transfer and self-check
A chiller pressure-decay test shows loss but locates no leak. What has it not established? It has not located the leak, so a qualifying locating method is still needed before calling it a complete leak inspection.
A certified technician is asked where EPA requires certification evidence to be kept. Which answer fits?
- The relevant stated condition is: A certified technician is asked where EPA requires certification evidence to be kept.
- Apply the relevant source rule. Technicians keep certification evidence at the business through three years after ceasing technician operations; EPA does not generally require carrying the card at every service call.
- This supports “At the place of business”. The alternative “Only in each customer's appliance manual” uses a different condition or conclusion;the applicable rule above explains why it does not answer this case.
Compare the other answer choices
This choice (Only in each customer's appliance manual) does not fit the stated conditions. Technicians keep certification evidence at the business through three years after ceasing technician operations; EPA does not generally require carrying the card at every service call.
This choice (Only in the recovery-machine maintenance log) does not fit the stated conditions. Technicians keep certification evidence at the business through three years after ceasing technician operations; EPA does not generally require carrying the card at every service call.
This choice (Only on the refrigerant cylinder label) does not fit the stated conditions. Technicians keep certification evidence at the business through three years after ceasing technician operations; EPA does not generally require carrying the card at every service call.
Try it, then explain it.
Complete a short set without looking at the example. After each answer, explain which evidence or rule supports your decision and why the alternatives do not fit.
