Which of the following safety precautions should be adhered to for low pressure systems?

Adhering to safety precautions for low-pressure systems is essential to ensure both personal safety and the proper handling of refrigerants. The correct choice encompasses all mentioned safety measures because they address various risks associated with working with refrigerants.

Firstly, not siphoning refrigerant by mouth is crucial as refrigerants can be toxic and harmful to ingest. This practice prevents accidental poisoning or adverse health effects.

Secondly, avoiding the spillage of liquid refrigerant on the skin is important because refrigerants can cause frostbite or skin irritation due to their low temperatures. This protection is vital in maintaining skin health and preventing injuries while handling refrigerants.

Lastly, using gloves and safety goggles is a standard safety measure when working with any chemical or hazardous material, including refrigerants. Gloves provide a barrier against skin exposure, while safety goggles protect the eyes from splashes or vapors that may irritate or damage eyesight.

The combination of these precautions forms a comprehensive approach to safely managing low-pressure systems, reinforcing the necessity of adhering to all recommended safety practices.
