OSHA 30 Hour Construction Program Practice Test

Which of the following is NOT a characteristic of heat stress?

1. Dizziness

2. Weakness

3. Coughing

4. Nausea

The correct answer is: Coughing

Coughing is not a characteristic of heat stress. Heat stress is primarily related to the body's inability to regulate its temperature in hot environments, leading to a range of symptoms directly associated with heat exposure. Common signs of heat stress include dizziness due to reduced blood flow to the brain, weakness as a result of fatigue from sweating and exertion, and nausea which can occur from overheating and dehydration. Coughing, on the other hand, is usually connected to respiratory issues, allergies, or infections and does not indicate heat stress or heat-related illness. Recognizing the specific symptoms of heat stress is crucial for timely intervention and treatment to prevent more serious conditions like heat exhaustion or heat stroke.
