Which action should be prioritized after confirming chemical exposure?

The priority after confirming chemical exposure is to administer first aid if trained. This action focuses on the immediate health and safety of the individual who has been exposed to the hazardous material. First aid can be critical in preventing further injury or health complications resulting from the exposure. Quick, effective first aid measures can stabilize a person's condition and may even save their life, as some chemical exposures can result in rapid deterioration of health.

Once first aid has been administered, additional steps like notifying local authorities, documenting the exposure details, or evacuating the area can be taken. However, the most pressing concern must always be the well-being of the individuals affected, which places administering first aid at the forefront of actions taken immediately following chemical exposure.
