Heat Kills! When I think of summer, I smile. It reminds me of good times, school is out, hanging with friends, Beach Boys music (oops showing my age), freedom and fun. But when you are working outside, heat is dangerous.
With this heat wave, companies and workers must do everything they can to keep safe.
Know the signs and symptoms of heat illnesses and what to do in an emergency situation.
Know what Federal OSHA will look for when they come out. California has an extensive heat regulation and requires companies to have a written program. See http://tinyurl.com/258fsrt for help in complying with California regulations..
Know how to protect yourself while working in heat.
SIGNS AND SYMPTOMS OF HEAT ILLNESS
Heat-related illnesses occur when a body is unable to cool itself. Older workers, workers in poor physical condition, workers with a poor diet or employees taking certain medications are more at risk. Some heat-related illnesses are: heat rash, heat cramps, fainting, heat exhaustion, and heatstroke. Heat stroke is the most serious and can result in death. However it is important to be able to recognize the symptoms of all heat-related disorders.
The following symptoms are commonly associated with the different heat illness medical conditions. Given the variability in recognition and reporting of heat illness symptoms, the information listed below should be used only as a general guideline.
Heat Rash (Prickly Heat) - Heat rash is a skin irritation caused by excessive sweating and clogged pores during hot, humid weather.
General Symptoms:
· Can cover large parts of the body
· Looks like a red cluster of pimples or small blisters
· Often occurs on the neck, chest, groin, under the breasts, or in elbow creases
· Uncomfortable so it can disrupt sleep and work performance
· Complicated by infections
Workers experiencing heat rash should:
· Try to work in a cooler, less humid environment when possible.
· Keep the affected area dry.
· Dusting powder may be used to increase comfort.
Heat Cramps - Heat cramps affect people who sweat a lot during strenuous work activity. Sweating makes the body loose salts and fluids and minerals. If only the fluids are replaced and not the salts and minerals painful muscles cramps may result.
General Symptoms:
· Painful muscle spasms in the stomach, arms, legs, and other body parts may occur after work or at night.
Workers with heat cramps should:
· Stop all activity, and sit in a cool place.
· Drink water.
· Do not return to strenuous work for a few hours after the cramps
subside because further exertion may lead to heat exhaustion or heat stroke.
· Seek medical attention if any of the following apply:
o The worker has heart problems.
o The worker is on a low-sodium diet.
o The cramps do not subside within one hour.
Fainting (Heat Syncope) - Employees who stand for long periods or suddenly get up from a sitting or lying position when working in the heat may experience sudden dizziness and fainting. In both cases, the fainting is caused by a lack of adequate blood supply to the brain. Dehydration and lack of acclimatization to work in warm or hot environments can increase the susceptibility to fainting. Victims normally recover consciousness rapidly after they faint.
General Symptoms:
· Sudden dizziness
· Light-headedness
· Unconsciousness
Workers with heat syncope should:
· Sit or lie down in a cool place when they begin to feel symptoms.
· Slowly drink water, clear juice, or a sports beverage.
· If they have or are fainting, call 911, notify their supervisor and make arrangement for transportation to medical facility.
Heat Exhaustion - Heat exhaustion is the body’s response to an excessive loss of the water and the salt contained in sweat. Older employees or those with high blood pressure are more susceptible to heat exhaustion. Cool temperature is not a valid indicator of a normal body temperature. Although the skin feels cool the internal body temperature may be dangerously high and a serious medical condition may exist.
General Symptoms:
· Heavy sweating
· Painful muscle cramps
· Extreme weakness and/or fatigue
· Nausea and/or vomiting
· Dizziness and/or headache
· Body temperature normal or slightly high
· Fainting
· Pulse fast and weak
· Breathing fast and shallow
· Clammy, pale, cool, and/or moist skin
Workers with heat exhaustion should:
· Move to cool area and replace fluids.
· If needed, call 9-1-1.
Heatstroke - Heatstroke is usually fatal unless emergency medical treatment is provided promptly.
General Symptoms:
· No sweating because the body cannot release heat or cool down
· Mental confusion, delirium, convulsions, dizziness
· Hot and dry skin (e.g., red, bluish, or mottled)
· Muscles may twitch uncontrollably
· Pulse can be rapid and weak
· Throbbing headache, shallow breathing, seizures and/or fits
· Unconsciousness and coma
· Body temperature may range from 102 - 104 °F or higher within 10-15 minutes
If the muscles begin to twitch uncontrollably, keep the person from self-injury. Do not place any objects in the mouth.
Monitor body temperature and continue cooling efforts until emergency medical treatment is provided to the victim.
Workers with heat stroke should:
· Get medical help immediately.
· Move employee to shady area and remove outer clothing.
· Wet skin and increase air movement around worker.
· Give fluids to drink.
NEVER leave a suspected heat stroke victim alone or let them go home.
Always seek medical help.
