Safety when Working with Refrigeration Equipment

What you need to know about refrigerants, electrical systems, and work processes

World Day for Safety and Health at Work (April 28) is an excellent opportunity to remind everyone about the importance of complying with safety standards, especially in high-risk areas such as industrial refrigeration equipment and HVAC systems.
Proper operation, refrigerant control, regular maintenance, and strict compliance with safety norms not only ensure safe working conditions but also extend the lifespan of your equipment.

When it comes to chillers for your production needs, choosing reliable equipment is not just a task — it’s a commitment to the safety of your employees and the efficiency of your business.
A faulty chiller can lead to various accidents and serious injuries, including mechanical damage, electric shocks, or the harmful effects of refrigerants on personnel health.
All these risks can be avoided by choosing a verified and high-quality unit.

In this article, we highlight the main risks professionals face when working with chillers and refrigerants, and what measures are necessary for safe and efficient operation of refrigeration systems.

Risks When Working with Refrigerants

Working with refrigerants (whether freons, ammonia, or alternative refrigerants) involves several specific risks that must be taken into account:

Toxic vapors during refrigerant decomposition

At high temperatures, refrigerants can break down, releasing toxic vapors that are hazardous to health.
This is particularly relevant for older refrigerants such as R-22 and R-134A, which, upon decomposition, release hydrogen chloride and hydrogen fluoride.
These vapors can cause irritation to the mucous membranes of the nose and throat and lead to severe headaches.

Risks of refrigerant leaks

A refrigerant leak can not only lower system efficiency but also pose a health hazard.
Vapors from refrigerants like R-32 or R-454B can displace oxygen, leading to asphyxiation.
To minimize this risk, all cooling systems, including chillers, must be equipped with leak detection devices.

Frostbite from contact with liquid refrigerant

Direct contact with liquid refrigerant can cause frostbite injuries to the skin and eyes.
It is critical that all personnel working with refrigerants are equipped with protective clothing and personal protective equipment (PPE), such as gloves and safety goggles.

Heart rhythm disorders

Prolonged exposure to refrigerant vapors can cause heart rhythm disturbances.
At very high concentrations, this can even lead to loss of consciousness.
It is essential to maintain recommended refrigerant concentration levels and regularly monitor air quality in working areas.

Safety measures for working with refrigeration equipment

To minimize risks and ensure safe operation, several key safety measures must be observed:

Personnel training

At EVROPROM, we provide comprehensive safety training for all specialists working with refrigeration equipment.
Each employee is certified for safe equipment operation, and certifications are regularly updated to keep pace with new standards and regulations.

Use of personal protective equipment (PPE)

Protective clothing, gloves, goggles, and respirators are mandatory for all personnel handling refrigerants.
Following PPE protocols helps prevent injuries from refrigerant exposure.

Refrigerant leak control

All refrigeration units must undergo regular leak testing.
At EVROPROM, we rigorously test every chiller before delivery to ensure system tightness and operational safety.

Monitoring and adjusting system parameters

Maintenance and pressure control

All systems, including compressors, must operate within safe pressure ranges.
Regular pressure checks are crucial to prevent emergency situations.

Refrigerant pressure monitoring

Electrical safety

Poor-quality electrical work or faults in chiller connection systems can cause short circuits and electric shocks.
All electrical work should be performed exclusively by qualified specialists with higher education in electrical engineering.

Wiring repairs

Quality control: reliability and safety

Before chillers are added to our inventory, they undergo a multi-stage testing process.
Each unit is checked for:

• System tightness — leak elimination.

• Pressure compliance — verifying operating pressures.

• Compressor performance — ensuring reliability.

• Temperature accuracy — confirming system performance.
