Answer :
Final answer:
A walk-in refrigerator or freezer must include an inside safety release and needs to maintain certain temperatures for food safety. They are not truly airtight as they need some level of air circulation to maintain temperature.
Explanation:
A walk-in refrigerator or freezer unit typically must include an inside safety release. This release allows individuals to open the door from the inside, even if it has been locked or shut tightly. This is vital to prevent accidentally trapping someone inside.
As for being air-tight, while these units need to have a good seal to preserve the cold temperature, they are not truly 'airtight' as this would prevent any air circulation, which is needed to maintain an even temperature.
The phrase 'must be within 98.5' is unclear. However, if we‘re considering Fahrenheit temperature, this is incorrect as the advised temperature for a refrigerator is below 4C (40F) and a freezer is below -18C (0F). These temperatures inhibit pathogens' multiplication, keeping food safe. Over 40F, food safety may be compromised.
