OSHA HEAT REGULATIONS OVERVIEW

2024 OSHA heat stress standards: How to automate compliance

With new OSHA heat stress regulations on the horizon, it is important to know how they can affect your organization. Perry Weather monitors heat stress on-site and sends an alert when the heat exceeds OSHA’s recomendations, keeping your team safe from the heat.

Current OSHA Guidelines for Heat Stress

Heat exposure in the workplace endangers millions of U.S. workers annually, causing thousands of illnesses with several cases ending in fatality. OHSA provides the following recommendations to combat the heat and stay safe in indoor and outdoor settings.

Prevention & Response Plans

OSHA recommends employers implement a comprehensive heat illness prevention plan,  educating workers on the risks, symptoms, and preventive measures of heat stress. Employers should also be prepared to respond to an incident, developing procedures to recognize symptoms of heat stress, apply first aid, and  contact emergency medical services.

Develop Work/Rest Schedules

Implement work/rest schedules based on the temperature, amount of PPE worn during certain tasks and amount of exposure. More strenuous tasks should be scheduled during cooler parts of the day and consistent hydration or rest breaks should be given during hotter hours.

Implement engineering controls

The implementation of engineering controls can lead to reduced heat exposure. Adding air conditioning or ventilation systems, shaded or cool rest areas, and reflective or heat-dissipating clothing can each be an effect approach.

Monitor heat conditions

OSHA recommends a few measurement methods for monitoring heat stress including heat index and wet bulb globe temperature (WBGT.) Although there is not yet a policy mandating the use of WBGT, OSHA prefers WBGT when monitoring heat stress and accounts for temperature, humidity, wind speed, and solar radiation.

Monitor, notify, and record with Perry Weather

Monitor conditions accurately

Perry Weather uses a 3.5-inch black globe sensor to measure WBGT, unlike handheld Wet Bulb Globe Temperature (WBGT) devices which use a smaller black globe. This leads to fluctuating measurements which are often higher, reducing the amount of time that workers can continue their labor.

Alert your team of hazardous conditions

Once Perry Weather determines that heat conditions have broke OSHA guidelines, it sends an alert to your team with a custom message letting them know exactly what they need to do. Depending on conditions this could mean taking a hydration break at predetermined intervals or a longer rest break in a climate controlled area.

Record historical data

Perry Weather records historical weather data allowing you to determine weather incidents were caused by heat stress from the on-site conditions and prove to stakeholders that conditions prevented your team from working during a given time.

How the upcoming OSHA heat stress ruling affects businesses

OSHA is aggressively developing additional regulations and initiatives to comprehensively address heat stress. The proposed standard would apply to all employers in the general industry, construction, maritime, and agriculture sectors conducting both outdoor and indoor work under OSHA’s jurisdiction.

Heat Injury and Illness Prevention Plan (HIIPP)

Employers would be required to develop a plan to handle heat risks. This plan should include safety rules, a heat safety leader, input from workers, and yearly reviews.

Identifying Heat Hazards

Employers must check for heat risks both outside and inside. This involves monitoring weather forecasts, measuring heat levels, and creating a plan with worker feedback.

Heat Illness and Emergency Response and Planning

Employers must have procedures in place for responding to heat-related illnesses and emergencies. This includes immediate actions and emergency response planning to protect employees from severe heat exposure.

Proposed Training and Recordkeeping Requirements

The proposed rule mandates initial and annual refresher training for supervisors, heat safety coordinators, and employees. Additionally, employers must maintain records of on-site measurements at indoor work areas for six months, ensuring compliance and safety.

When to take action to prevent heat illness

OSHA’s proposed rule includes an initial heat trigger and a high heat trigger that each requires certain actions be taken. The initial heat trigger is a heat index of 80°F or WBGT equal to NIOSH’s recommended alert limit, while the high heat trigger is a heat index of 90°F or WBGT equal to NIOSH’s Recommended Exposure Limit.

  • Easily access historical WBGT values in the Perry Weather dashboard

Get more work time with Perry Weather

Handheld WBGT devices often read higher than Perry Weather, leading to less time working even when conditions might not be hazardous. This is due to the smaller size of the black globe sensor on handheld devices. Here’s how Perry Weather is different:

  • Equipped with a Large 3.5 inch Black Globe Sensor for accurate measurments
  • Sends you alerts when the WBGT gets to high, keeping your team safe
  • Stationary system that doesn’t need to warm up to give you an accurate measurment

Frequently Asked Questions

Find answers to the most common questions we get from prospective customers, or connect with our team to learn more.

How much does it cost?

We’ll build a quote for your organization. Quotes can vary based on a variety of factors like number of units, number of users, and other optional hardware options. You can rest assured that we’ll design a solution that fits your budget. Talk with our team to learn more.

We use free/cheap weather apps. What’s the difference?

Free weather apps are great for everyday personal use, but extremely limited for use in industries like solar, gas, and construction.

You can’t build weather safety policies that notify your organization about what actions need to be taken in a weather safety situation. The data can be up to an hour old and coming from the nearest airport miles away, often painting a dramatically different picture than the true conditions at your site. Learn more by talking with our team.

Can I switch if I already have another system in place?

Many of our customers came from using other systems and haven’t looked back.  Let us tell you why.

I use a handheld device to monitor Wet Bulb Globe Temperature (WBGT). Isn’t that good enough?

Handheld devices certainly have a place, but instructions must be followed closely, and those instructions are prone to human error (versus standalone, permanent devices). Additionally, handhelds only address one problem in the bigger picture of weather safety.

Perry Weather gives you a complete weather safety toolkit to monitor a wide spectrum of weather conditions from lightning to wind chill, keep your team on the same page through policy-driven alerts, and automatically log historical on-site conditions for simple reporting.

Why would I want on-site hardware?

Our platform includes outdoor warning system(s) and an on-site weather station. Without an outdoor warning system, you’re depending on your staff to always be on-site and constantly checking their phones for notifications, which may not be possible at all times. Without an on-site weather station, conditions will be pulled from the nearest government weather station, typically located at an airport. This data can be up to an hour old and miles away from your location. Talk with our team to find out whether on-site hardware makes sense for your organization.

What if I want a custom forecast for my team?

We have your back. Our team of full-time meteorologists are on-call and ready to answer your questions over text message, phone, or email. Whether you’re trying to make a go/no-go decision based on weather, need a custom forecast, or simply need to know when a lightning delay will end, we’re ready to help.
