The action to lift the red cover and activate the emergency valve on the EOT must be repeated until the HEU shows vented pressure. In an emergency venting scenario, you need to actively trigger the emergency valve so pressure is released step by step. The HEU indicator provides the confirmation that venting has occurred; you keep performing the valve activation cycles until that reading confirms vented pressure. Merely checking the HEU, watching the venting, or notifying someone does not accomplish venting by itself, though those steps may accompany the process. The key is repeatedly engaging the emergency valve under the red cover until the system indicates it is fully vented.
