If a solvent used to clean electrical equipment spills on your arm and begins to burn, what is the best source for first aid information?

The best source for first aid information in the case of a solvent spill is the material safety data sheet (MSDS). The MSDS provides crucial details specific to the chemical involved, including information on its properties, health effects, and appropriate first aid measures. It is tailored to the specific solvent and contains the manufacturer’s recommendations on how to handle various emergency situations that may arise from exposure.

Using the MSDS is vital because it delivers accurate, scientifically-backed guidelines that are specifically relevant to the solvent in question. This ensures that the first aid response is appropriate and effective for that specific chemical's properties and potential hazards.

While resources such as the American Red Cross handbook can be beneficial for general first aid information, they may not have the specific details needed for a particular solvent. An internet search engine could lead to unreliable or non-specific information, and relying on a coworker may provide anecdotal advice that may not reflect correct or safe practices. Thus, for a precise and safe response in the event of exposure to harmful substances, the MSDS is the most reliable source for immediate first aid guidance.
