Hot Weather Safety Basics Extreme heat, like that often experienced during the summer months, can be hazardous for those who work, or spend an extended amount of time, outdoors. It is not only the heat that poses the threat, but also what weather forecasters refer to as the “heat index.” The heat index is the combination of high temperatures, humidity and direct sun exposure that contributes to heat stress. Anyone who spends time working or playing outside on a hot day should take basic precautions to guard against the heat, sun exposure and other hazards.

Top Off FluidsExperts recommend that those working outdoors in elevated temperatures drink about five to eight ounces of water every 15 to 20 minutes to stay sufficiently hydrated and maintain a safe core body temperature. Studies show that a person’s alertness and endurance are compromised after only one hour in extreme heat conditions.

After two hours, the effects of heat stress—which include cramps, fatigue, decreased strength and reduced coordination—may set in. To keep maintain proper hydration, it is important to drink before, during and after exercise to replace body fluids. By the time you’re thirsty, you’re already dehydrated. Water is best for hydration, but sports drinks, which contain electrolytes lost in perspiration, are an alternative.

Cool water is more quickly absorbed by the body than warm or very cold fluids. Avoid coffee, tea and alcoholic beverages, all of which act to dehydrate the body.

Sun SafetySunlight contains ultraviolet (UV) radiation that causes premature aging of the skin, wrinkles and skin cancer. The amount of damage from UV exposure depends on the strength of the light, the length of exposure and whether the skin is protected. To block the sun’s

harmful rays, cover up. Wear a wide brimmed hat and tightly woven clothing — preferably a long sleeved shirt and long pants. To gauge the protection offered by your clothing, see if you can see your hand through the fabric. If you can the garment offers minimal protection.

Eye protection is important, too. Wear UV-absorbent shades. Some studies have shown a greater incidence of cataracts among those who do not wear sunglasses in bright sunlight.

Use sunscreen with a sun protection factor (SPF) of at least 30, and limit your exposure. UV rays are most intense between 10 a.m. and 4 p.m. and are present even on cloudy days.

Prolonged Heat Events U.S. summers commonly produce heat waves—several consecutive days of excessively high temperatures in a given geographical area of the country. Because of the health hazards posed by excessive heat, the National Weather Service (NWS) developed the following heat-related alerts:

An excessive HEAT WATCH is issued when an excessive heat event is likely to occur in the next 24 to 72 hours. A watch provides enough lead time to prepare for a potential extreme heat event.

An excessive HEAT WARNING or HEAT ADVISORY means an excessive heat event is in progress, imminent or expected. Either of these is issued within 12 hours of the onset of extremely dangerous heat conditions. A warning is used for conditions posing a threat to life or property. An advisory is issued for less serious conditions that cause significant discomfort or inconvenience, which, if caution is not taken, could lead to a threat to life or property.

Get the AppOSHA and NIOSH have developed an app available through the App Store or on Google Play. The Heat Safety Tool can be used for planning outdoor work activities based on how hot it feels throughout the day.

Staying Safe in the Heat

Who’s at risk?Those working directly in the sun in high temperatures or high heat are at risk for heat-related illness. The risk increases with heavy physical labor or inadequate �uid consumption.

Those who are unaccustomed to high heat or who wear waterproof clothing have a higher risk of heat sickness.

Headache, dizziness, or fainting; lethargy and clammy skin; irritability or confusion; and thirst, nausea or vomiting are all signs of heat exhaustion. Provide assistance to keep the situation from escalating.

Confusion, passing out and seizures as well as an inability to sweat may indicate that a person has heat stroke. This is a serious condition. SEEK HELP IMMEDIATELY.

Preventative StepsDrink often, at least 16 oz. �uid each hour (If you feel thirsty, it’s too late!)

Wear sunscreen and protective clothing

Avoid alcohol and ca�eine

Take breaks, if possible

Know the Signs

Heat-related illnesses can be very serious. Be familiar with the risks and signs. If someone becomes ill from the heat, move the person to a cooler area and contact a supervisor. Do not leave them alone.

If a person is not alert or seems confused, he or she might have heat stroke. Contact a supervisor and CALL 911 IMMEDIATELY. Administer �rst aid and apply ice as soon as possible.
