Sonicu has extensive experience in this area, having successfully implemented similar solutions for several clients in California, where CALOSHA has been a pioneer in these regulations.

Sonicu is a trusted partner for organizations that prioritize compliance, and we are well-equipped to meet your regulatory needs.


We offer more than a year of data storage for your logs and
our sensors are completely wireless, cost-effective, and easy to deploy.


Our alerting system is highly customizable, providing notifications via text, email, phone calls, and push notifications.

These alerts can be configured to repeat and escalate, ensuring that the appropriate personnel are promptly informed and can take necessary action.

Our sensors are compact, resembling hockey pucks in size and shape, and are IP67-rated for durability.  They measure both ambient temperature and humidity, with our cloud-based software automatically calculating the heat index.


Our software also offers sophisticated multi-site management features, enabling you to efficiently oversee multiple divisions. Site managers can be granted access only to their specific areas, while corporate managers can monitor all locations and divisions from a centralized dashboard.


An additional feature that has been particularly popular with our manufacturing and warehouse clients is the ability to display heat index scores on large screens.

 

This provides frontline workers with real-time visibility of their work environment's conditions.

Furthermore, we offer a variety of reports that can be delivered to you via email at your preferred frequency.  These reports range from detailed regulatory documents suitable for audits to managerial summaries that help identify areas requiring further training.

Cal/OSHA's Heat Illness Prevention in Indoor Places of Employment regulation applies to most indoor workplaces, such as restaurants, warehouses, and manufacturing facilities where temperatures can get high.

For indoor workplaces where the temperature reaches 82 degrees Fahrenheit, employers must take steps to protect workers from heat illness. Some of the requirements include providing water, rest, cool-down areas, methods for cooling down the work areas under certain conditions, and training.

Employers may be covered under both the indoor and outdoor regulations if they have both indoor and outdoor workplaces

Why Has OSHA Issued A New Mandate?

The Occupational Safety and Health Administration, OSHA, is now working on new heat standards that target indoor workers without climate-controlled environments. 

It is particularly for workers employed for labor in warehouses, manufacturing facilities, and distribution centers. 

If you’re in a leadership position at any of these types of facilities, please don’t take this new mandate lightly. 

Sonicu was alerted to this new practice when two warehouse operators became customers AFTER they were cited by OSHA. 

Back in June 2021, the Acting Assistant Secretary of Labor for Occupational Safety and Health Administration, Jim Frederick, announced that the agency was working on a new set of guidelines. 

These new guidelines were linked to reported climate change trends detected over the last 18 years, some of the hottest years on record. 

The increased intensity of heat waves has put the lives of many people at risk and the federal government is following the lead of a handful of states and municipalities which are taking this threat to employees very seriously. 

From 2001 to 2019, rising temperatures in California alone resulted in approximately 20,000 workplace injuries, indoors and outdoors including. 

Similarly in 2019, 43 workers died from heat illnesses while over 2400 suffered injuries from heat hazards at work. However, this number rose to 61 in 2021.

New heat waves are potentially damaging the productivity and output of businesses, alarming administrators and waking up regulators to a growing threat of heat stress at work, both indoors and outdoors. 

According to the Atlantic Council’s Adrienne Arsht-Rockefeller Foundation Resilience Center, heat-related illnesses from the workspace have cost businesses at least $100 billion per year.

This rate is set to double by 2030.

It’s also important to note that while OSHA didn’t have any rulings on temperature and humidity in office settings.

Now with over 111 safety and labor groups, including the Public Citizen, legislators have been urged to create new federal standard guidelines that protect indoor (and outdoor) workers from heat-related illnesses.

Definitions.
“Acclimatization” means temporary adaptation of the body to work in the heat that occurs gradually when a person is exposed to it. Acclimatization peaks in most people within four to fourteen days of regular work for at least two hours per day in the heat.

“Heat Illness” means a serious medical condition resulting from the body's inability to cope with a particular heat load, and includes heat cramps, heat exhaustion, heat syncope, and heat stroke.

“Environmental risk factors for heat illness” means working conditions that create the possibility that heat illness could occur, including air temperature, relative humidity, radiant heat from the sun and other sources, conductive heat sources such as the ground, air movement,  workload severity and duration, protective clothing and personal protective equipment worn by employees.

“Landscaping” means providing landscape care and maintenance services and/or installing trees, shrubs, plants, lawns, or gardens, or providing these services in conjunction with the design of landscape plans and/or the construction (i.e., installation) of walkways, retaining walls, decks, fences, ponds, and similar structures, except for employment by an employer who operates a fixed establishment where the work is to be performed and where drinking water is plumbed.

“Oil and gas extraction” means operating and/or developing oil and gas field properties, exploring crude petroleum or natural gas, mining or extracting oil or gas, or recovering liquid hydrocarbons from oil or gas field gases.
“Personal risk factors for heat illness” means factors such as an individual's age, degree of acclimatization, health, water consumption, alcohol consumption, caffeine consumption, and use of prescription medications that affect the body's water retention or other physiological responses to heat.

“Shade” means blockage of direct sunlight. One indicator that blockage is sufficient is when objects do not cast a shadow in the area of blocked sunlight. Shade is not adequate when heat in the area of shade defeats the purpose of shade, which is to allow the body to cool. For example, a car sitting in the sun does not provide acceptable shade to a person inside it, unless the car is running with air conditioning. Shade may be provided by any natural or artificial means that does not expose employees to unsafe or unhealthy conditions and that does not deter or discourage access or use.

“Temperature” means the dry bulb temperature in degrees Fahrenheit obtainable by using a thermometer to measure the outdoor temperature in an area where there is no shade. While the temperature measurement must be taken in an area with full sunlight, the bulb or sensor of the thermometer should be shielded while taking the measurement, e.g., with the hand or some other object, from direct contact with sunlight.
