Understanding Construction Heat Illness
Heat illness is a spectrum of conditions caused when the body cannot adequately cool itself. In construction, workers face extreme heat exposure from high temperatures, physical exertion, and work environments that trap heat.
Types of Heat-Related Illness
**Heat stroke** is the most severe and life-threatening heat illness: - Body temperature rises to 104 degrees F or higher - Confusion, altered mental status, loss of consciousness - Hot, dry skin (sweating may stop) - Rapid heartbeat and breathing - Seizures may occur - Without immediate treatment, death or permanent brain damage can result
Heat stroke is a medical emergency requiring immediate cooling and 911 activation.
**Heat exhaustion** is the precursor to heat stroke: - Heavy sweating - Weakness and fatigue - Cold, pale, clammy skin - Fast, weak pulse - Nausea or vomiting - Muscle cramps - Headache and dizziness
If not addressed, heat exhaustion can progress to heat stroke.
**Heat cramps** are painful muscle spasms: - Usually affect legs, arms, or abdomen - Caused by loss of electrolytes through sweating - May occur during or after strenuous work - Warning sign that the body is overheating
**Heat syncope** is fainting or near-fainting: - Caused by blood pooling in the legs - Often occurs when standing for long periods - More common in workers not yet acclimated - Risk of secondary injuries from falling
**Heat rash** is skin irritation from excessive sweating: - Red clusters of small blisters - Usually on neck, chest, groin - Can become infected - Impairs sweating, worsening heat regulation
All of these conditions can develop in New York construction workers during hot weather, particularly when proper precautions are not taken by employers and site owners.
