Extremes of Cold: Temperature sufficiently low to cause marked bodily discomfort unless the worker is provided with exceptional protection.
Temperature Changes: Variations in temperature which are sufficiently marked and abrupt to cause noticeable bodily reactions.
3 - Extremes of Heat Plus Temperature Changes
Extremes of Heat: Temperature sufficiently high to cause marked bodily discomfort unless the worker is provided with exceptional protection.
Temperature Changes: Variations in temperature which are sufficiently marked and abrupt to cause noticeable bodily reactions.
4 - Wet and/or Humid Conditions
Wet: Contact with water or other liquids.
Humid: Atmospheric condition with moisture content sufficiently high to cause marked bodily discomfort.
5 - Exposure to Noise and Vibrations
