Learning Event 1:
OPERATE CAMERAS AND LABORATORY EQUIPMENT IN TROPICAL CLIMATES
1.
Excessive heat and humidity can cause a very high incidence of failure in photographic equipment.
There is no known way to eliminate these failures completely. Failures can be reduced by proper preventive
procedures. When you are working in tropical climates, you must know what to look for and how to protect your
equipment from the excessive heat and humidity found in this environment.
2.
There are two primary causes of equipment failure in tropical climates, corrosion and fungus.
a. Corrosion is a chemical action that eats away metal. Corrosion can attack and destroy metal and
electrical contacts very quickly. This action increases with a rise in temperature. For each increase of 18F or
