Heat and Safety

Heat can be a dangerous thing for a farmer. It can cause direct harm if you get so hot that your body can't handle it. It can also add to your overall stress load. Stress can be a big contributor to accidents, and that's even more true when you can hardly see because of the sweat dripping into your eyes.

How can you stay safe and keep your help safe during hot weather? By doing what you can to keep cool, and by being extra aware of the hazards around you. Here are some ideas.

  • Get set for safety. When you're stressed by heat, you don't always think about safety basics. Before you head into the hot, busy summer, make sure you're set for safety (see box).
  • Drink plenty of water. To stay healthy in hot weather, drink lots of water -- at least eight large glasses a day, more if you're really working up a sweat. To tell if you're drinking enough, check the color of your urine. If it's dark, drink more water.
  • Wear cool clothes. Light-colored, loose-fitting clothing made of natural fibers such as cotton will help you stay cool. Socks made of materials such as Polypropylene™ and Thermax™ will help your feet stay cool and dry. A wide-brimmed hat can help you stay comfortable, too.
  • Take time to cool off. Splash yourself with water occasionally. Take breaks in the shade. Five minutes spent cooling off may be five minutes you're not getting stuff done. But it's a lot less time off than a run into the emergency room -- or a lifetime in a wheelchair if you suffer from an accident related to being stressed by heat.
  • Watch for heat exhaustion and heatstroke. Heatstroke is a life-threatening condition in which your body loses its ability to control its own temperature. Your pulse races, you stop sweating, you may get dizzy, your body temperature soars. To give first aid to a person with heatstroke, cool them down with a cold water bath until their temperature drops to 101°F (oral) and massage their body to keep blood circulating. Get to a doctor immediately. If distant from a hospital, wrap the person in a cold, wet sheet or wet the person's clothing with cool water.
  • Plan around the heat. You already plan your day around the rain forecast. Think about the heat forecast, too. Avoid strenuous work if it's super hot. The term for doing hard physical labor in extreme heat when you could save it for a cooler day is not "macho." It's "stupid."
  • Watch the sweat factor. Sweat is good because as it evaporates it helps cool your skin. But it can also make your hands slippery and impede your vision. Be alert to these possibilities and be extra careful when performing everyday tasks when you're sweaty.
  • Quit while you're ahead. Heat exhaustion occurs when you are low on water and electrolytes. Symptoms are cold, clammy skin and a slowed pulse. If you think you might have heat exhaustion, stop working. If you start feeling dizzy or sick to your stomach, get out of the sun, drink lots of fluids, and take it easy the rest of the day. You've had too much.
  • Watch your workers. Your help, whether hired hands or family members, may hesitate to slow down for the heat because they don't want you to think they're wimps. Give them permission to take care of their health and safety by adjusting their (and your) expectations in hot weather.

Watch Those Rays

Summer not only brings heat, it also brings plentiful sun. To people who work outdoors, that also means increased risk of skin cancer. Farmers are three times as likely to get skin cancer as the general population. Skin cancer can kill you. It's worth your while to try to prevent it. How? Extension textiles and apparel specialist Sherri Gahring offers the following tips:

  • Avoid the sun if possible between 10 a.m. and 3 p.m.
  • Wear a wide-brimmed hat or a hat with a backflap, long-sleeved shirt, and long pants when in the sun. A baseball cap does not provide adequate protection!
  • Apply sunscreen with SPF 15 or higher 30 minutes before you go outside. Reapply every three hours. Use sunscreen even on cloudy days, since cancer-causing rays aren't stopped by clouds.
  • Use lip balm with sunscreen. The lower lip is one of the most common sites for skin cancer.
  • Wear sunglasses that filter out UVA and UVB radiation.
  • Avoid the sun if you're taking medicine, such as antibiotics, that make you more sensitive to light. Check with your doctor if you're not sure.
  • Ask your doctor to check you for skin cancer at your regular annual physical. Be sure he or she knows you have an outdoor occupation.
