What could be a potential risk if a service engineer encounters acid burns while handling refrigerants?

When a service engineer encounters acid burns while handling refrigerants, the primary concern is skin damage. Refrigerants can sometimes break down and form acidic byproducts, especially if they are exposed to moisture or high temperatures. These acidic substances can cause significant harm to the skin, leading to burns, irritation, or more severe injuries.

In addition to immediate physical injury, skin damage may require medical attention and can lead to complications such as infections or long-term sensitivity. The risk emphasizes the necessity of appropriate safety equipment, such as gloves and protective clothing, when handling refrigerants to prevent direct contact and exposure.

While acid burns could potentially lead to other issues, such as inhalation of harmful fumes or interactions with other materials that could cause fire hazards, the most direct and immediate consequence in this scenario is the damage to the skin itself. Proper awareness and safety measures can mitigate these risks effectively.
