High Temps, High Humidity Create Deadly Combination

OSHA will launch its Summer Safety Campaign for workers, “Water. Rest. Shade,” on the first day of summer, June 20. However, even if you have a 'cushy desk job' chances are you'll be spending some time outside in the next few days, and may feel inspired to get some work done around the house, and in the heat.

Given the hot spell that's now upon us, the timing couldn't be better. Here are a few resources for you to take advantage of, whether you're a roofer or a desk jockey, or are tempted to exercise your 'normal routine'.

• OSHA has released a free application for mobile devices that enables workers and supervisors to monitor the heat index at their work sites. The app displays a risk level for workers based on the heat index, as well as reminders about protective measures that should be taken at that risk level. Available for Android-based platforms and the iPhone, the app can be downloaded in both English and Spanish by visiting http://s.dol.gov/RI.

• Additionally, a Web page provides information and resources on heat illness ‒ including how to prevent it and what to do in case of an emergency ‒ for workers and employers. The page is available at http://www.osha.gov/SLTC/heatillness/index.html. This page includes artwork, videos and other resource material such as PSAs.

OSHA is also partnering with the National Oceanic and Atmospheric Administration (NOAA) on weather service alerts. NOAA’s Heat Watch page now includes worker safety precautions when extreme heat alerts are issued.

What happens when you're affected by the heat?

The body normally cools itself by sweating. During hot weather, especially with high humidity, sweating isn't enough. Body temperature can rise to dangerous levels if precautions are not taken. Heat illnesses range from heat rash and heat cramps to heat exhaustion and heat stroke. Heat stroke can result in death and requires immediate medical attention.

How can heat illness be prevented?

Remember three simple words: water, rest, shade. Drinking water often, taking breaks, and limiting time in the heat can help prevent heat illness. In addition:

1. Pace yourself — If you are not used to working in the heat, start slowly and increase the pace gradually. If exertion makes your heart pound and leaves you gasping for breath, STOP all activity. Get into a cool area or at least in the shade and rest, especially if you become lightheaded, confused, weak or faint.

2. Drink plenty of fluids — During heavy work, drink two to four glasses (16-32 ounces) of cool fluids each hour. A sports beverage, such as Squincher, can replace the salt and minerals you lose in sweat. Liquids that contain caffeine or large amounts of sugar can cause you to lose more body fluid. Also avoid very cold drinks, because they can cause stomach cramps.

3. Wear lightweight, light-colored, loose-fitting clothing — Protect yourself by wearing a wide-brimmed hat, sunglasses and by using sunscreen of SPF 15 or higher.

4. Limit outdoor activity to morning and evening hours — Take rest breaks often in shady areas so your body will have a chance to recover.

5. Use a buddy system — Heat-induced illness can cause people to become confused or lose consciousness. When working in the heat, monitor the condition of your co-workers and have someone do the same for you.
