What should you do if you're in a confined space and your gas detector alarms with a high toxic level?

If you're in a confined space and your gas detector alarms with a high toxic level, the priority is to ensure safety by evacuating the area immediately. Toxic gases can pose serious health risks, including unconsciousness or even death, depending on the concentration and duration of exposure. Immediate evacuation helps to remove personnel from a dangerous situation and allows for proper assessment and response to the gas leak without risking anyone's health or safety.

Continuing to work despite the alarm puts individuals at risk of exposure to harmful gases, while checking for leaks could further delay necessary action and worsen the situation. Investigating the cause of the alarm is also not advisable in this context, as the priority should be to ensure that all personnel are safe from potential toxicity before any investigation or remediation is carried out. Therefore, evacuating the confined space immediately is the correct and most responsible action to take in response to an alarming situation with high toxic levels.
