Heat Stress Among Coastal Workers: Risks, Recognition, and Prevention

With temperatures regularly exceeding 30°C and humidity levels above 80%, the Kenyan coastal environment presents genuine heat stress risks for outdoor and industrial workers. Heat-related illness ranges from minor heat cramps to life-threatening heat stroke — and the transition can be rapid.

Who Is Most at Risk?

High-risk groups include: port and dockside workers, construction crews, agricultural workers, security personnel in heavy uniforms, and any employees working near heat-generating industrial equipment.

Clinical Signs to Watch For

• Heat cramps — muscle spasms after heavy work; first sign of salt/fluid depletion
• Heat exhaustion — heavy sweating, weakness, cold/pale/clammy skin, fast weak pulse, nausea
• Heat stroke — high body temperature (above 39.5°C), hot/red/dry skin, rapid strong pulse, possible unconsciousness — MEDICAL EMERGENCY

Engineering and Administrative Controls

• Schedule heavy work during early morning or late afternoon hours
• Ensure access to cool drinking water (250ml every 15–20 minutes during heavy exertion)
• Provide shaded rest areas and enforce regular rest breaks
• Implement acclimatisation programs for new workers
• Train supervisors to recognise early warning signs
