Last summer was a season of record-breaking heat in and we have no reason to expect a break from heat and humidity this summer. AIM members are always looking for information about how to help employees cope with the warmth of the sun.

Before we discuss some of the issues associated with heat, we want to make sure you’re aware of a new OSHA initiative that may impact your company beginning this summer and for the next three years.

New OSHA Initiative

The Occupational Safety and Health Administration (OSHA) recently announced a new heat in the workplace initiative.

The new National Emphasis Program (NEP) turns OSHA’s focus on more than 70 high-risk industries in indoor and outdoor work settings when the National Weather Service has issued a heat warning or advisory for a local area.

On days when the heat index is 80° F or higher, OSHA inspectors and compliance assistance specialists will engage in outreach and technical assistance to help stakeholders keep workers safe on the job. Inspectors will look for and address heat hazards during inspections, regardless of whether the industry is targeted in the NEP. More information is available on the program through this link.

Is your company on the list?

The complete directive is available at this link.  Once you open the link, please go to Appendix A for a list (by 4-digit industry code) of the industries the new initiative is targeting.

Back to Summer

Heat can present significant health challenges for your workforce. Some of those challenges include:

• How hot is too hot at work?
• What should an employer do when it gets too hot for employees at work?
• What resources are available to help employers assist employees dealing with excessive heat?

Hot enough for you?

Although Massachusetts has guidelines defining what is too cold in the workplace in winter, it has none defining too hot in the summer. Many employers are left to their own common sense and experience to determine what to do during summer’s heat waves.

According to the National Weather Service heat is the number-one weather-related killer of people in the United States. Excessive heat has caused the death of an average of more than 100 people per year over the past decade. Most years, more people die per year from heat-related illness than from tornadoes, hurricanes, floods and lightning combined.

Heat waves are usually predicted in advance by the National Weather Service, giving employers an opportunity to prepare.  Relying on information from the National Weather Service (www.weather.gov) web site allows employers and employees to prepare for the impact of sky-high temperatures.

Hot Town, Summer in the City

If a company has a workplace that is open to the weather, such as a loading dock, an outdoor warehouse, a construction site, an outdoor deck or patio for food service or even an outdoor exercise area or some other non-air conditioned site, the company needs to be alert to heat-related disorders.

Heat disorders generally occur when the body is unable to remove heat by sweating, or from excessive sweating. When heat gain exceeds what the body can deal with, or when the body cannot compensate for fluids and salt lost through perspiration, the body’s inner core temperature begins to rise, and heat-related illness may develop.

Heat stroke is the most serious form of heat-related illness. It happens when the body is unable to regulate its core temperature. Sweating stops and the body can no longer rid itself of excess heat. Signs include confusion, loss of consciousness, red hot dry skin, and seizures. Heat stroke is a medical emergency that may result in death.   If a person exhibits these symptoms, call 911 immediately.

The following additional steps may save a worker’s life:

• place worker in a shady, cool area,
• loosen clothing,
• remove outer clothing,
• fan air on worker,
• place cold packs in armpits,
• wet worker with cool water,
• apply ice packs, cool compresses, or ice if available,
• provide fluids (preferably water) as soon as possible, and
• stay with the worker until help arrives.

Heat exhaustion is the body’s response to loss of water and salt from heavy sweating. Signs include headache, nausea, dizziness, weakness, irritability, thirst, light headedness and heavy sweating.

In response to heat exhaustion have the worker sit or lie down in a cool, shady area, drink plenty of water or other cool beverages, apply cold compresses/ice packs, take the employee to a clinic or emergency room for medical evaluation or treatment if signs or symptoms worsen or do not improve within 60 minutes and do not have the worker return to work that day.

Heat cramps are caused by the loss of body salts and fluid during sweating. Low salt levels in muscles cause painful cramps. Tired muscles—those used for performing work—are usually the ones most affected by cramps. Cramps may occur during or after working hours. In response to heat cramps, have the worker rest in a shady, cool area, and drink water or other cool beverages. Wait a few hours before allowing worker to return to strenuous work, and have the worker seek medical attention if the cramps don’t go away.

Heat rash, also known as prickly heat, is skin irritation caused by sweat that does not evaporate from the skin. Heat rash is the most common problem in hot work environments. If an employee develops heat rash, try to have the worker work in a cooler, less humid environment when possible and keep the affected area dry.

Apps can help

OSHA has developed an app to help. The app contains information and ideas on dealing with summer heat. The App’s information is also accessible in Spanish by clicking on the en Español link.

The App allows employers to calculate the heat index for their worksites, and, based on the heat index, advise workers what the risk level is.  Then, with a simple click, they can get reminders about the protective measures that should be taken at that risk level to avoid heat-related illness –reminders about drinking enough fluids, scheduling rest breaks, planning for and knowing what to do in an emergency, adjusting work operations, gradually building up the workload for new workers, training on heat illness signs and symptoms, and monitoring others for signs and symptoms of heat-related illness.

OSHA also has a fact sheet on working outdoors in hot conditions employers may find helpful.

Additionally, OSHA is partnering with the National Oceanic and Atmospheric Administration to incorporate worker safety precautions when heat alerts are issued across the nation. NOAA also includes worker safety information on its heat watch web page.

Call OSHA at 1-800-321-OSHA (6742) or visit www.osha.gov to learn more about its resources for dealing with the heat.

What can an employer do to reduce the risk of heat danger?

Encourage employees to adopt some of the following health tips to manage their possible reaction to the heat.  Education, planning and properly reacting to the conditions will assure safety during the hot events of summer.

• Workplace schedules – Find ways to allow your employees to slow down. If possible, limit strenuous activities to the coolest time of the day, perhaps first thing in the morning or when the sun is not directly shining on your worksite.  Consider extending break periods or adding a break period to ease the heat risk during certain days. Or if possible, adjust the work schedule to avoid the hot hours of the day.
• Clothing – Dress appropriately for summer. Lightweight light-colored clothing reflects heat and sunlight, and helps a body maintain its normal temperature.
• Fluids – Encourage employees to drink plenty of water or other fluids even if they may not feel thirsty – the body needs water to keep cool. Consider providing bottles of water and sports drinks to ensure hydration.
• Be cool – Allow employees to spend as much time as possible in air-conditioned places. If air conditioning is unavailable, consider using fans to keep air circulating, and encourage employees to work in the shade if possible.
• Healthy eating – Remind employees that diet matters. The heavier the meal, the more a body works to digest it and the greater the water loss, causing a greater risk of heat related problems.
• Teamwork – make sure your employees watch out for one another. Train them to recognize the symptoms of a co-worker suffering from heat-related illness, and to seek help from their supervisor, the company safety offices, human resources, or by dialing 911 if the symptoms are severe.

If you have other strategies that have worked at your company and would like to share them with other AIM members, please forward the idea to Tom at tjones@aimhrsolutions.com;  Terry  at tcook@aimhrsolutions.com or Sarah at spiscatelli@aimhrsolutions.com for inclusion in a future HR Edge issue. Or if you are a season’s pass member for the roundtable you could access our slack channel to share your ideas there.

AIM members with questions about this or any other human-resources issue may contact the Employer Hotline at 1-800-470-6277.
