What is the primary immediate action required in the event of an allergic reaction at work?

In the event of an allergic reaction at work, the primary immediate action required is to call 911. This is crucial because allergic reactions can escalate quickly and may lead to severe complications, including anaphylaxis, which can be life-threatening. Calling emergency services ensures that medical professionals can arrive promptly to provide the necessary treatment, such as administering epinephrine and additional care.

Notifying co-workers could be helpful in some situations, such as seeking assistance, but it does not address the immediate medical needs of the individual experiencing the allergic reaction. Providing a beverage or checking for a medical ID may offer some support or context, but neither substitutes for professional medical intervention when someone's health is at risk. The focus in an emergency should always be on securing immediate medical assistance.
