Understanding gas concentration units is vital for workplace safety and accurate hazard assessment.
🔹 Percentage (%) – Used to express higher gas concentrations, such as oxygen levels during confined space assessments.
🔸 Parts Per Million (PPM) – Used to measure low concentrations of gases like CO, H₂S, and SO₂, which may pose health risks even at low levels.
📌 Knowing how to interpret gas readings helps HSE professionals identify hazards and take appropriate safety measures.
