Climatic hazards
Exposure to heat, frost and humidity (condensation) can occur if no climate controls are employed within warehouse or containers. High humidity can be the most serious hazard affecting compression strength of a corrugated box, even if it is well designed. Studies show cyclical temperatures and humidity changes can have dramatic effect on box compression strength.
There are several hazards associated with outside climate. These include exposure to precipitation (rain,snow or other variations of precipitation),temperature and humidity (prevailing, changing and cyclic) and exposure to light or solar radiation. Liquid water may present itself as rain,condensation or ship sweat (condensation on cold ship walls)
