61. Physical hazards in the workplace – industrial microclimate.

What is meant by "industrial microclimate"?

The specific thermal, humidity, and air movement conditions in a workplace environment that can affect worker health and efficiency.

What are the main physical hazards related to industrial microclimate?

• Heat exposure

• Cold exposure

• Atmospheric pressure changes (hyperbaric and hypobaric)

What are common health conditions caused by hot microclimate?

• Heatstroke

• Heat exhaustion

• Heat syncope

• Heat cramps

• Burns

What is thermal stress vs. thermal strain?

• Thermal stress: Combined external heat + internal metabolic heat

• Thermal strain: Body’s physiological response (e.g., increased HR, sweating)

Which workers are at higher risk from heat exposure?

• People with diabetes, hypertension, heart/skin diseases, thyroid disorders, anemia

• Those taking medications affecting thermoregulation

What are common cold-related conditions?

• Trench foot

• Chilblains

• Frostbite

• Hypothermia

What general effects does cold have on the body?

• Shivering

• Bradycardia

• Hypotension

What contributes to cold injuries in the workplace?

• Humidity

• Wind

• Contact with cold surfaces

• Inadequate clothing

• Poor health

How can workers be protected from cold microclimates?

• Proper clothing

• Windshields

• Acclimatization

• Heated environments
