Health & Safety

EPA refrigerant regulations are changing quickly, and for many facility owners, plant managers, and HVAC/R contractors, keeping up with the details can feel overwhelming. Between the AIM Act’s HFC phasedown, updated safety standards, and new handling requirements, it’s easy to wonder whether your equipment, and your team, are truly prepared.

In industrial and commercial refrigeration systems, safety is non-negotiable. These systems often operate under high pressures and involve refrigerants that can be hazardous if released unintentionally. One of the most critical components that ensures system safety, and protects both people and property, is the pressure relief valve (PRV). Pressure relief valves are often the unsung heroes of refrigeration safety, silently standing guard to prevent catastrophic overpressure events. Let’s take a deeper look at their importance, how they work, and what best practices facility owners should follow to keep them functioning as intended.

When it comes to workplace performance, most employers focus on training, technology, and culture. But there’s one powerful factor that often goes unnoticed: indoor air quality (IAQ).

Allergens like pollen, dust mites, mold spores, and pet dander don't just exist outside: they circulate through your indoor air, impacting occupant comfort, productivity, and health. For commercial and industrial facilities, controlling allergens isn't just about comfort: it’s about creating healthier indoor environments, reducing employee sick days, and maintaining efficient system operation.

Ammonia (R-717) has long been a leading refrigerant in industrial refrigeration systems thanks to its high energy efficiency, zero global warming potential (GWP), and low cost. But as beneficial as ammonia is, it also comes with unique safety risks, most notably its toxicity and potential for serious harm if leaked.

In the world of commercial and industrial refrigeration, safety and compliance are non-negotiable. As systems grow more complex, and the consequences of a leak or failure grow more severe, adhering to industry standards is essential for protecting your people, property, and operations.

In today’s commercial and industrial spaces,air quality and energy efficiency are more critical than ever. While HVAC systems are essential for maintaining comfortable indoor temperatures, their ability to deliver clean, healthy airis equally important. At the heart of this process is proper air filtration.Whether you manage an office building, manufacturing facility, hospital, or school, understanding the role of air filtration in your HVAC system can help improve occupant health, system performance, and energy savings.

Air filters are the first line of defense for your HVAC system. They trap dust, dirt, allergens, and other particles from the air before it enters the system.

Ammonia refrigeration systems are widely recognized for their efficiency and environmental benefits, but they are not without challenges. One of the common issues that can arise over time is water contamination in closed-circuit systems. While this might not sound like a major concern, the accumulation of water in ammonia refrigeration systems can lead to significant operational problems and efficiency losses if not properly addressed.

Ammonia refrigeration systems are highly efficient and widely used in industrial settings such as food processing, cold storage, and manufacturing. However, while ammonia offers many advantages as a refrigerant, including cost efficiency and environmental benefits, it also poses potential safety hazards due to its toxicity and flammability. Therefore, it is critical to have proper ventilation and detection systems in place to ensure safe operation and protect both employees and the surrounding community.

Cooling towers are a vital component of many industrial and commercial facilities, playing a key role in regulating temperature and maintaining efficient operations. However, these systems also pose significant health risks if not properly maintained, as evidenced by the recent Legionnaire’s disease outbreak linked to cooling tower water systems. Proper water treatment is essential to ensure the safety, efficiency, and longevity of your cooling towers.

At the IIAR Conference and Heavy Equipment Expo in Long Beach, California, Travis Townsend from Northstar Refrigeration and Mark Malagon, P.E., from Nexus Refrigeration, presented an important discussion on the dangers of over-pressurization in secondary cooling systems, particularly relating to ammonia leaks. This presentation was inspired by a HAZWOPER refresher training video on the Fernie BC incident by WorkSafeBC, highlighting the dire consequences of inadequate maintenance and emergency procedures.
