A commercial supermarket rack system contains more than 50 pounds of refrigerant and develops a leak. Once the owner exceeds the applicable annual leak rate, the leak generally must be repaired within:
a.24 hours
b.7 days
c.90 days
d.30 days
Giải thích
For appliances containing 50 or more pounds of refrigerant, leaks that exceed the applicable annual leak rate threshold must generally be repaired within 30 days of discovery. A 24-hour or 7-day deadline is stricter than the rule requires, and 90 days is too long. If repairs cannot be completed in time, the owner may need a retrofit or retirement plan.
