For safety, when is it critical to check for ignition sources during refrigerant work?

• A. During breaks
• B. After work is done
• C. Prior to starting work
• D. Only if a leak is suspected

Answer: (C)

Checking for ignition sources prior to starting work is crucial because it directly addresses safety concerns associated with handling refrigerants. A2L refrigerants, although considered to have lower global warming potential, can still be flammable under certain conditions. By identifying and mitigating potential ignition sources—such as open flames, sparks, or hot surfaces—before beginning work, one significantly reduces the risk of fire or explosion. This preventative step is essential in maintaining a safe working environment, as it allows workers to take necessary precautions, such as ensuring proper ventilation and removing any flammable materials, before they engage with refrigerants. Conducting this assessment at the start of the work effectively sets a safety-first mindset and ensures all necessary measures are in place to safeguard personnel and property throughout the job.
