What should be the first action taken before using an aerosol product?

Before using an aerosol product, the first action should be to read the instructions and warning statements. This step is crucial as it provides essential information regarding the proper use of the product, safety precautions, and any hazards associated with its use. Understanding these instructions ensures that the product is used safely and effectively, minimizing the risk of accidents or injuries.

Additionally, reading the warnings can help identify necessary protective measures, such as whether gloves or goggles are needed, and can provide guidance on the correct method of application. This foundational knowledge is vital before proceeding with other actions, such as shaking the can or ensuring proper ventilation, as it prepares the user with the critical knowledge needed to handle the product safely.
