The question presents three blanks asking for immediate first aid steps after a burn or chemical spill on the skin, followed by a prompt for whom to inform. I will address each part in turn, noting the given answer and context.

First blank – what should you do first? Options (as implied by the typical safety guidance you’d encounter): immediate actions include washing with running water, avoiding wiping with towels, and not delaying until advice is sought. The most appropriate immediate action is to immediately wash the skin under running water. This aligns with standard first-aid protocols for chemical exposures and burns, where prompt irrigation helps to dilute and remove irritants and cool the skin. Alternatives like cleaning up the spill and then washing, or using a sodium bicarbonate solution, or washing with cold or hot water, are not correct as described: wiping with paper towels can spread contamination; a chemical-specific solution (like sodium bicarbonate) is not universally appropriate and can delay proper irrigation; water at extreme temperatures (cold or hot) can cause further tissue damage or be less effective than running cool or tepid water.

Second blank – how long should you wash your skin for? Options include 30 seconds, 1 minute, 5–6 minutes, 10–20 minutes, 1 hour, or don’t wash your skin. The standard guidance is a prolonged rinse, typically around 10–20 minutes, to ensure ample removal of irritants and cooling of the burn. Short durations like 30 seconds or 1 minute are not sufficient, and very long durations such as 1 hour are impractical and unnecessary in most cases. Not washing at all would be dangerous in chemical exposure scenarios.

Third blank – whom should you inform? The provided answer indicates Lab Demonstrator. In a laboratory or classroom setting, it is appropriate to inform the lab supervisor, lab demonstrator, instructor, or designated safety officer about the incident so that the proper documentation and additional steps can be taken. While other roles like a supervisor or safety officer could also be valid depending on the setting, the specific provided answer points to the Lab Demonstrator as the immediate point of contact or authority in this context.

Putting it together, the reasoning highlights: (a) start with immediate rinsing under running water, (b) continue rinsing for about 10–20 minutes, and (c) inform the Lab Demonstrator for proper management and reporting. Note that this analysis is based on standard first-aid practices for skin exposure to burns and chemicals and reflects typical classroom or lab protocol; if your specific course or workplace has different procedures, you should follow those. If any of the given options differ in your material, use the closest principles—rapid irrigation, adequate rinsing time, and alerting the appropriate authority—to guide your actions.
