Summer is here and that means we can expect hot and humid weather soon. But for those who work in greenhouses and outdoors, it can make for long—even dangerous—days. That’s why we here at Hortica want to help you protect your workers.

According to the Occupational Safety and Health Administration (OSHA), in 2014, 2,630 workers had some kind of heat illness. 18 of them died from heat stroke and related causes on the job. But heat illnesses and deaths are preventable—if you know what to do. That’s where a prevention program comes in. OSHA recommends employers:

  • Provide workers with water, rest, and shade
  • Allow new or returning workers to gradually increase their workloads and take more frequent breaks until they’ve built a tolerance for working in the heat
  • Train workers how to avoid and identify heat illness
  • Observe workers for signs of trouble

Normally, the body sweats to cool off in hot and humid weather. But if it’s particularly humid, sweating may not be enough. That can cause the body’s internal temperature to rise to a dangerous level. That’s when heat exhaustion or heat stroke can strike. There are some things you can have your workers do to protect themselves:

  • Drink water every 15 minutes—even if you aren’t thirsty
  • Take a rest in the shade to cool down
  • Wear a hat and light-colored clothing

Working in full sunlight can increase heat index values by 15 degrees, so extra rest and water breaks are required. Tasks that require heavy protective clothing or equipment can also make a worker more susceptible to heat illnesses. Be sure to check on them at regular intervals, but realize all workers are at risk during a heat wave. Here’s what to look out for:

Heat exhaustion

Call a supervisor for help or 911 if they’re not available if you see signs of:

  • Dizziness
  • Headache
  • Cramps
  • Weakness
  • Sweaty skin
  • Nausea, vomiting
  • Fatigue

Heat stroke

Call 911 immediately and notify your supervisor if you see signs of:

  • Lack of sweating with red, hot, dry skin
  • High body temperature (only a medical professional can get an accurate reading)
  • Rapid pulse
  • Difficulty breathing
  • Confusion, strange behavior, agitation, hallucinations, disorientation
  • Convulsions/seizures
  • Fainting

If your worker shows signs of heat exhaustion or heat stroke, here are some basic first aid measures:

  • Have someone stay with the worker until help arrives
  • Start the cooling process immediately
    • Get the person into the shade or air-conditioning
    • Fan while misting the victim with water to promote evaporation and cooling
    • Give them fluids if they’re conscious and able to drink (do not give alcohol or caffeine)
    • Remove outer clothing if possible
    • Apply cool water to the victim using what’s available (garden hose, sponge, shower, etc.)
  • Place ice packs or cool towels on the back of their neck, under armpits, and groin
    • If the person stops breathing, perform CPR

It’s important to understand the dangers of heat illnesses and the things you can do to prevent your workers from getting hurt, or worse.
