Heat Illness
Participants learn to recognize the risk factors, signs, and symptoms of heat-related illnesses—
including heat rash, cramps, exhaustion, and life-threatening heat stroke—and understand
procedures for immediate response and emergency medical care.
This course delivers required training on preventing heat illness in compliance with Cal/OSHA
standards: Title 8, Section 3395 (Heat Illness Prevention in Outdoor Places of Employment) and
Title 8, Section 3396 (Heat Illness Prevention in Indoor Places of Employment, effective July
2024).
Participants learn to recognize the risk factors, signs, and symptoms of heat-related illnesses—
including heat rash, cramps, exhaustion, and life-threatening heat stroke—and understand
procedures for immediate response and emergency medical care. Key topics include:
• Personal risk factors (e.g., acclimatization, health conditions, clothing/PPE) and employer
responsibilities under Cal/OSHA.
• Preventive measures: importance of frequent hydration (cool drinking water always
available), access to shade (outdoor: required at ≥80°F) or cool-down areas (indoor:
maintained <82°F), adequate rest breaks, and high-heat/high-radiant-heat procedures.
• Acclimatization protocols, especially for new or returning workers.
• Supervisor-specific duties: monitoring workers, enforcing breaks, and ensuring effective
communication.
• Emergency response: how to report symptoms, call for help, and provide first aid.
The training covers both outdoor environments (e.g., agriculture, construction, landscaping)
where shade and high-heat triggers (≥95°F) apply, and indoor settings (e.g., warehouses,
manufacturing, restaurants) triggered at ≥82°F (with enhanced controls at ≥87°F or in highradiant-
heat areas/clothing restrictions).
