Ten Hot Weather Safety Tips:

1. Stay hydrated. Drink plenty of fluids; drink about 16 ounces before starting and 5 to 7 ounces every 15 or 20 minutes.
2. Avoid dehydrating liquids. Alcohol, coffee, tea and caffeinated soft drinks can hurt more than help.
3. Wear protective clothing. Lightweight, light-colored and loose-fitting clothing helps protect against heat. Change clothing if it gets
completely saturated.
4. Pace yourself. Slow down and work at an even pace. Know your own limits and ability to work safely in heat.
5. Schedule frequent breaks. Take time for rest periods and water breaks in a shaded or air conditioned area.
6. Use a damp rag. Wipe your face or put it around your neck.
7. Avoid getting sunburn. Use sunscreen and wear a hat if working outside.
8. Be alert to signs of heat-related illness. Know what to look for and check on other workers that might be at high risk.
9. Avoid direct sun. Find shade or block out the sun if possible.
10. Eat smaller meals. Eat fruits high in fiber and natural juice. Avoid high protein foods.
