What should you be careful of to prevent heat disorders in the workplace? In light of the growing incidence of heat disorders in recent years, Japan's Ministry of Health, Labor, and Welfare has set out specific guidelines. Let’s find out with Pocari!

Environmental management

Lower heat stress by using the WBGT (Wet Bulb Globe Temperature) heat index. The WBGT heat index takes into account temperature, humidity, radiation, and airflow. The incidence of heat disorders goes up as the WBGT rises. Measure the WBGT during work and compare it to the WBGT standard according to the physical work intensity. If the WBGT exceeds this standard, there is a high chance of heatstroke, and it is vital to take measures to lower the WBGT.

Ways to lower the WBGT of the environment

• Attempt to lower the WBGT at worksites using heat masking shields, ensuring sufficient ventilation, and using air conditioning
• Switch to work that is less intense physically.
• Change the worksite, etc.

Provide rest areas

When a worksite is hot and humid, set up a cool, air-conditioned rest area nearby. Provision of the rest area with ice in coolers, thermoses of cold beverages (0.1-0.2% saline, electrolyte beverages, oral rehydration solutions, etc.), and salty snacks to enable periodic replacement of fluid and salt (sodium). It is also a good idea to have cold damp towels, showers, and other facilities that allow for workers to cool down.

Establish periodic breaks and shorten continuous work times in hot and humid workplaces. Also, adjust the intensity of the physical work according to the weather and the health condition of the individuals.

Clothing

Try to wear moisture-permeable clothing with good ventilation properties. When working under direct sunlight, it is advisable to wear something that wards off the sun, such as a cap, or a cool helmet. Bright colors that reflect radiant heat are recommended, and the use of cold packs can be effective.

Supply of body fluids

Even if you are not thirsty, body fluids must be replaced periodically during work, as well as before and after work. Have 0.1-0.2% saline, electrolyte beverages, and oral rehydration solution on hand in convenient locations such as worksites and rest areas.

Drink POCARI ion supply drink

You can supplement POCARI after a heatstroke to promptly and accurately compensate for the amount of water and nutrients needed by the body. POCARI has a composition equivalent to the amount of body fluid lost every day and is absorbed into the body 2.2 times faster than water, helping to promote blood circulation and provide essential ions such as Na+, Cl-, Ca2+, Mg2+, K+… help restore the body's best state.

On the other hand, POCARI also has 5 "green criteria": NO GAZ, NO CAFFEINE, NO PRESERVATIVES, NO COLORANTS, NO SACCHARINE, will always be a great assistant in work every day.

First aid

• Prepare an emergency contact network and ensure others are aware of it
• Relevant people should be made aware of emergency manuals and the phone numbers and locations of hospitals and clinics.
• If someone develops the symptoms of heat disorders at a hot and humid work site, it is important to first move the person to a cool location, remove clothing, and cool the body. If the person cannot drink fluid on his or her own, take him or her to a medical institution immediately, even if the person remains conscious.
