temperatures.
5.7.3.2 Indicate the type and thickness of insulation to be applied to the walls, floor, and ceiling
of the refrigerated spaces. Also describe the space conditions under which the insulation can
be applied and discuss any special requirements (e.g., ventilation) that must be met with regard
to safety and health of the installing personnel.
5.7.3.3 Identify the type and capacity of the refrigeration equipment to be used.
