July is Heat Safety Month, and justifiably so. In the Summer of 2022, high temperatures wreaked havoc across the globe. The U.S., Europe, India, Pakistan, and other parts of the world experienced record-breaking heatwaves that were not only miserable—they were dangerous, killing thousands of people. Even worse, scientists predict these extreme heat events will become more frequent and more deadly in the future as human-caused climate change shifts weather patterns and makes them harder to predict.

What, then, is a company to do in the face of these dangerous conditions? What’s expected of them and, more importantly, how can they protect their people and operations? Here, we’ll discuss tips for working in the heat to keep your people safe and your organization chugging along despite the adverse conditions.

How to Implement Heat Safety Tips in the Workplace

As you evolve your heat safety procedures with the tips in this article, think about how they will fit into your overall safety strategies. These tips will be the most helpful when they are ingrained into the safety culture of your business and implemented consistently. Here’s how you can make the most of these heat safety recommendations.

Update workplace policies

Once you’ve identified a tip that applies to your employees or operations, it’s not enough to make a note of it. Make it a functional part of your existing workplace safety policies. For example, if you have a section in your safety code about proper working gear, be sure to include any new modifications related to heat, such as wearing UV-protective clothing that can keep workers cool. With all safety information organized together, you can manage regular policy updates and trainings effectively.

Train employees on heat precautions

It’s imperative that any changes to your safety procedures—including sections that manage the threat of hot weather—are accompanied by timely training for the entire workforce. Just as you train employees to know how to handle a fire drill, a natural disaster, or a cybersecurity breach, you need to conduct effective training sessions so all employees are aware of the dangers, warning signs, and action steps in cases of heat exposure and heat stress.

Repetition of trainings is key to ensure employees’ skills and knowledge stay fresh, especially during a particularly hot season. Include heat safety training in the onboarding process for all new workers too.

Solicit feedback and revisit policies

Once you’ve accounted for the dangers that hot weather can pose to your people and business, commit to continuous improvement. Regularly solicit feedback about policies and feelings of safety from employees who actually work in the heat. If they find current procedures and support sufficient, then you’re on the right track—as long as you make updates when needed.

However, if employees say they find the policies unhelpful or cumbersome, it’s time to review procedures, as well as employee engagement. When employees don’t understand or respect rules, they are more likely to ignore them—which in the case of extreme heat, can lead to dangerous consequences. Prioritize changes to make your policies more effective and easy to follow.

Here are five critical heat safety tips to implement today:

Workplace heat safety tips

1. Provide Adequate Hydration

As internal body temperature rises, the body tries to keep itself cool, and sweating is the primary way it does so. By releasing water through our skin, evaporation of that water into the ambient air has the side effect of also taking some of our unwanted body heat with it. However, sweating can easily lead to dehydration, a dangerous condition that can cause seizures, shock, brain swelling, and even death. The only way to prevent dehydration in sweaty conditions is to ensure workers drink enough water.

This is a no-brainer to most, but it’s so essential to keep top of mind, especially when providing enough drinking water can be difficult or inconvenient. Indoor environments and other places with running water make it easy to provide a continuous source of cool water to workers, and water fountains or coolers should be installed if they aren’t already.

Some work environments, however, make providing water not so simple. Construction crews, utility workers, and others who work in places without clean running water need to have easy access to sufficient drinking water. Plastic coolers are portable ways to dispense drinking water to entire crews and can hold many gallons of liquid to keep workers hydrated throughout the day. Ensure that if you use this solution, you have enough coolers for your entire job site and they are filled and refilled when running low. OSHA recommends that each worker drink one pint of water per hour.

2. Cool Down Your Worksite and Workers

Some workers are lucky enough to count on a comfortable work environment day in and day out, but for many, it’s an unavailable luxury. People who labor outdoors, in warehouses, in mines, and in other exposed environments are at the mercy of the elements. That is, unless their employers protect them from such hazards.

While it’s not possible to completely eliminate the sun’s heat from many worksites, there are accessible ways to minimize the discomfort and danger. These include:

  • Setting up shaded areas out of the direct sun for rest periods
  • Issuing light-colored and loose-fitting clothing/uniforms
  • Using fans to increase air movement
  • Installing tinted windows and reflective exterior surfaces
  • Use sunscreen and UV-blocking clothing to avoid sunburn

The modes of cooling available to organizations will vary depending on the nature of the jobs and locations, so be sure to consider your unique circumstances when setting up for work.

3. Create a Heat Safety Plan

The dangers that come with working in hot climates may be severe, but they are also generally predictable. Just as you would create a risk management plan for other disruptive events, like a natural disaster, so too can you plan for heat exposure.

The exact plan that you devise will be specific to your business, location, and the work, but there are some commonalities. Here are the things you should consider including in your workplace heat safety plan:

  • Designate a “heat safety officer” who provides daily oversight during hot working conditions
  • Assess worksite hazards that might contribute to heat danger
  • Develop a heat safety training curriculum
  • Create work schedules that distribute hot-weather work among multiple employees
  • Allow for adequate cooling breaks
  • Devise a method for measuring heat stress among employees
  • Plot out what you will do in the case of a National Weather Service heat advisory
  • Use the NIOSH heat safety app (or similar tool) to determine the heat risk of the job site
  • Create a response plan in case someone is in need of medical attention

Once you have a plan in place and can see it in action, it’s critical that you continuously reflect and improve upon it. After each heat safety incident, the heat safety officer and their colleagues should look back on what went well and what can be improved for next time.

Why protecting workers from heat stress matters

The effects of heat on human bodies can vary among people and episodes, but it’s vital that all workers and supervisors know the potential dangers and how to spot them. If left untreated, high body temperature can cause heat illnesses, including heat stroke, heat rash, and heat cramps. It can also reduce one’s ability to function and can result in fatigue, dizziness, muscle spasms, and even brain damage and death.

4. Look Out for One Another

Working in the heat is often so dangerous because the symptoms of heat exhaustion can sneak up on you quickly. Unless you keep a thermometer on you at all times, you can’t check your internal body temperature at will. That’s why it’s important to look out for each other.

Heat stroke, one of the most common heat-related illnesses, counts confusion and a loss of consciousness among its symptoms. By their nature, these symptoms are very hard—or even impossible—to notice in yourself. That’s why implementing a “buddy system” can be crucial: it makes it much more likely that someone will notice the signs of heat stroke in their work buddy. Workers on their own are much less likely to notice this in themselves due to the symptoms of heat stroke, such as impaired cognition and awareness. Training your employees on situational awareness can also help them spot signs of danger earlier before more serious symptoms kick in.

Train all of your workers in proper heat-related first aid procedures. If they notice a coworker suffering from heat illness, they should know how to take care of them. Cooling heat-stroked workers down should be priority number one, and the fastest way to do so is with cold water or an ice bath. If that’s not available, move the worker to a cooler, shaded area and use wet towels to cool them down as much as possible while you call 911 for help.

You might also consider adding more workers to tasks that usually require fewer. The multiple advantages include increasing the number of people who can spot heat illness in their coworkers and spreading the physical stress of the work across more people, decreasing the chance that one person over-exerts themself.

5. Ease into Strenuous Work

Humans are capable of adapting to just about any climate on earth, but that doesn’t mean that we can casually begin working during a sudden heat wave with no ill effect. Rather, we have to slowly ramp up to working in the heat to allow our bodies to adjust.

The CDC recommends giving workers one to two weeks to acclimate to excessive heat fully. On the first work day of a high-heat event, schedule workers to labor for only 20% of their usual workday. If a worker is able to perform well and safely on that day, then increase by another 20% to a total of 40% of their usual workload on the following day. Continue this trend until you reach the normal workload for your employees.

Acclimatization is an important part of adjusting to hot-weather work, but it won’t be a uniform process across all of your employees. Some people are simply more apt to adjust to hot climates quickly, and others aren’t. Workers with certain disabilities or low levels of physical fitness are more likely to have a harder time adjusting to hot environments.

Monitor employees closely for signs of heat illness during this period of acclimatization. If workers are finding it difficult to keep up with the gradual increase in work from day to day, allow them more time to adjust. Allow for frequent breaks in shade or air-conditioning. Even during the acclimatization process, people need occasional relief from the heat—do not deprioritize cooling rest breaks.

In short, make sure to individualize your approach to hot weather adjustment.

Prioritize Employee Safety

No matter what environmental conditions your business contends with—be it inclement weather or other natural disasters—it’s imperative that you put employee safety on the highest pedestal. Not only is it your duty of care and the moral thing to do, but it will also ensure your operations aren’t hamstrung by unexpected heatwaves. By preparing for work in high temperatures, you’re protecting your people and your organization.
