The maximum temperature for holding cold potentially hazardous food is 41°F (5°C) or lower. This temperature helps inhibit the growth of harmful bacteria that can thrive in warmer conditions. It is essential to regularly monitor and maintain this temperature to ensure food safety.

135ºF or above.
Temperature class XX refers to a specific classification used in explosion protection standards, indicating the maximum surface temperature of equipment that can be safely operated in potentially explosive atmospheres. Each class is designated with a letter and number, where the letter represents the type of gas or dust, and the number signifies the maximum temperature limit. This classification helps ensure that equipment does not ignite hazardous substances in industrial environments. Understanding temperature classes is crucial for compliance with safety regulations and ensuring operational safety.
Since hard-cooked eggs are a potentially hazardous food, the maximum time they should be kept at room temperature is 2 hours.
When the air is saturated, it means that it holds the maximum amount of water vapor that it can at a given temperature and pressure. This often leads to humidity or potentially precipitation if the conditions are right.
If the relative humidity is 50 percent, the air is holding half of the maximum amount of water vapor it can hold at that temperature. This means the air is holding 50 percent of the water vapor it could potentially hold.
The temperature at which air reaches saturation is called the dew point temperature. At this temperature, the air is holding the maximum amount of water vapor it can hold at that specific temperature, leading to condensation or saturation.

You are pushing the envelope with 3 hours. Potentially hazardous food should not be left out of the refrigerator for more than 2 hours. If it is very warm - as at a summer picnic - then 1 hour is the maximum. At that point, it should be refrigerated or re-heated.

Relative humidity expresses the amount of water vapor present in the air as a percentage of the maximum amount of water vapor the air can hold at that temperature. For example, if the relative humidity is 50%, it means the air is holding half of the maximum water vapor it can hold at that temperature.
Relative humidity is a comparison of the amount of moisture that air is holding compared to the maximum amount it could hold at a given temperature. If it's holding all that it can, the relative humidity is 100%.
