According to Section 5(a)(1) of the Occupational Safety and Health Act of 1970, every employee is entitled to a safe workplace, free of known hazards. However, there has been no federal standard on heat stress that prescribed how companies were required to protect employees from a high-temperature work environment.

Until now.

On September 20, 2021, OSHA announced it would be exploring new standards to protect workers from heat hazards, both indoors and out.

In their release, OSHA stated that “43 workers died from heat illness in 2019, and at least 2,410 others suffered serious injuries and illnesses.” The Atlantic Council’s Adrienne Arsht-Rockefeller Foundation Resilience Center, estimates “the economic loss from heat to be at least $100 billion annually – a number that could double by 2030 and quintuple by 2050 under a higher emissions scenario.”

With these figures in mind, OSHA is hosting a virtual Stakeholder Meeting on OSHA Initiatives to Protect Workers from Heat-Related Hazards on May 3, 2022.

What We Know Right Now

If your company has kept up on training and OSHA regulations, you know that federal heat stress standards aren’t clearly defined. Rather than explicit regulations regarding heat stress, more generic “guidelines” have been somewhat open to interpretation. As Industrial Hygiene in the Workplace noted in their April newsletter, “employers have a duty to protect workers from recognized serious hazards in the workplace, including heat-related hazards.” However, without a clear standard, companies can currently choose what that duty requires of them.

Additionally, OSHA’s regional divisions have developed standards for those residing in areas with higher temperatures, but adopting a national standard has been overlooked until now. With the alarming rate of heat-related injuries nationwide, OSHA is taking a closer look at measures to address this issue.

What To Expect in OSHA’s New Heat Standards?

The standards will change, and regulations will very likely become more difficult for employers to manage. Although we can’t predict the outcome with certainty, we can take a page from OSHA’s regional directives for higher temperature regions and expect similar policies to emerge.
The OSHA Regional Emphasis Program for Heat Illnesses for Arkansas, Louisiana, Oklahoma, New Mexico, and Texas requires daily analysis of the Heat Index and employers to take additional measures on days forecasted above 80°F. More training, additional first aid kits, drinking water, acclimation accommodations, and provisions for immediate care are all detailed within the program. It’s safe to assume that this will be used as a baseline for the federal standard, as well.

Experts are also weighing in on their expectations for this new standard. According to Courtney Malveaux, an employment attorney at the law firm Jackson Lewis in Richmond, VA, “There’s going to be more emphasis on indoor work, and heat standards are going to be a complex calculus—not just temperature.” OSHA did announce that in developing the standard, they plan to “gather diverse perspectives and expertise on topics, such as heat-stress thresholds, heat-acclimatization planning, and exposure monitoring.”

Malveaux goes on to say, “Almost all of them [heat-related deaths] are preventable. We understand how bodies heat up. And we understand the interventions. People don’t need to die in the heat. These are unnecessary deaths.”

Outside

There’s not much you can do about the outdoor temperatures. However, these new regulations will require you to change the way outdoor work gets done.

For outdoor/indoor combination environments, you can expect to:
- Allow more time for acclimation to hotter environments (the CDC currently recommends that employees gradually increase heat exposure over a 7-14 day window).
- Provide cooler environments indoors by offering air-conditioned areas as a reprieve.
For exclusively outdoor working environments, you may be required to:
- Hire additional workers to compensate for additional break times.
- Provide relief from the heat in the form of shelter, shade, water, and ventilation.

Inside

For traditional factory environments, you may be expected to:
- Purchase additional equipment to decrease your facility’s ambient temperature.
- Provide free, easily accessible water for employees to maintain hydration
- Offer more frequent breaks to allow employees to cool off.

For Class II Environments, (and more on those below) there will likely be more strict regulations:
- Expect factories with these environments to be hit harder than factories without.
- All the traditional regulations and then some.
- Mandated maximum working hours (overtime limitations).

Heat Standards in Class II Environments

According to NFPA 70, a Class II Environment is defined as a location where:

1) Ignitable concentrations of hazards exist under normal operating conditions and/or where the hazard is caused by frequent maintenance or repair work or frequent equipment failure; or

2) Ignitable concentrations of hazards exist under abnormal operating conditions.

If your facility is a Class II environment, (one in which combustible dust is an everyday battle, e.g., paper, feed, and corn mills, metal powder manufacturers, or coal plants), preventing or cleaning combustible dust buildup should already be part of your maintenance plan. However, you can expect much stricter enforcement on your implementation of their preventative heat measures as well.

This is not only because dust build-up creates a greater risk for combustion, but also because cleaning the rafters manually will put workers in one of the hottest places in your facility: overhead spaces. When your dust maintenance plan requires workers to enter these areas, they’re in more danger due to heat stress and lower air quality.

This is where SonicAire can help your employee’s safety and allow you to maintain constant compliance with OSHA’s regulations. Our dust control fans will keep your employees out of the rafters in extreme temperatures while also preventing the combustion risk that comes when you combine the fugitive dust with potential ignition sources.

Dust buildup doesn’t have to be an expected problem, even for Class II environments. With a SonicAire fan system, designed especially for your facility, you’ve prevented the problem from ever occurring and are averting the risk before OSHA cracks down on a federal heat standard.

What This Means for Your Company

As you well know, OSHA’s regulations nearly always have consequences for your facility’s operations. These regulation updates will undoubtedly impact all manufacturing companies to some degree. If you’re already in a region that enforces a heat standard, you may not see as dramatic of an impact, but federal regulations and enforcement can be different from regional.

Of course, you’ll have time to comply. OSHA doesn’t expect or require overnight changes to procedure and/or equipment. You can expect similar timeframes to other OSHA Standards Development. They will typically allow 30-60 days to comply with new rules and regulations.

It’s possible you may see an increase in OSHA inspections after that timeframe, though. As you likely know, OSHA requires no warning before they show up, and the reasoning behind the inspection can be anything from worker complaints to workplace injury. Even targeted inspections for increased heat in the area may put your facility on OSHA’s inspection radar.

Your facility will need to make every effort to show OSHA that you’re complying with these regulations. Inspectors will identify areas of concern for your operations. This will include direct sunlight, hot equipment, furnaces, boilers, ovens, etc.

You’ll also be required to maintain the preventative equipment and tools needed to minimize heat’s effect on your employees.

These changes may be genuinely detrimental to your company’s bottom line. But, being aware of them sooner rather than later may save you headaches in the long run.

Getting Ahead of New OSHA Heat Standards

The time to act isn’t when you’re on the clock. Don’t wait until the inspection occurs to start your heat standard compliance. Your company should be the trendsetter, the standard by which other companies are compared.

When your facility has a problem with fugitive dust, sending your staff into high-temperature environments creates additional dangers. You may already be taking the precautions that this initiative will regulate, but if not, you’ll want to get ahead of the curve.
