Heat Illness Prevention for Outdoor Crews

Heat Illness Prevention

Landscaping crews work in direct sun during peak heat hours. Heat stroke is a medical emergency; heat exhaustion can sideline a worker for days.

Prevention Steps

• Drink 1 cup (8 oz) of water every 15 to 20 minutes during heavy work, not just when thirsty
• Take shade breaks during the hottest part of the day (10 AM to 2 PM) when possible
• Schedule the hardest physical work (digging, hauling) for early morning
• Wear light-colored, loose-fitting moisture-wicking clothing
• Never work alone on extremely hot days; buddy checks can catch early symptoms

Warning Signs

Heat exhaustion: Heavy sweating, pale skin, nausea, dizziness, muscle cramps. Move to shade, cool with water, rest.

Heat stroke: No sweating, hot red skin, confusion, loss of consciousness. This is a 911 emergency.

OSHA Requirement

OSHA requires employers to provide water, shade, and rest under the Heat Illness Prevention standard. New workers must have acclimatization time over their first 7 to 14 days.
