Prolonged contact with heat is considered to be a dangerous act. The duration and intensity of the heat can have an everlasting impact, and, sometimes, can be fatal.
Contact with heat is the contact of a body part, or whole body, with a heat source. The heat source can be a naked flame, hot gases, steam or any other form of heat with a temperature that can cause burns (1st degree, 2nd degree, or 3rd degree). For example, if a worker is working in a kitchen, then there is a chance that he might come into contact with a heat source (stove, oven, geyser, etc.). If he contacts a naked flame, then the burn on the skin will be the point of contact with heat.
