Final answer:
When splashed with an acid, immediately (b) wash the exposed skin thoroughly to prevent further injury, then inform your supervisor and refer to the Safety Data Sheets (SDS) for further instructions.
Step-by-step explanation:
If you are accidentally splashed with an acid, the best thing to do first is b) Wash exposed skin thoroughly. Immediate action is required to prevent injury. Under an emergency situation where acid comes into contact with your skin, time is of the essence. Quickly washing off the acid can limit the amount of damage to your skin. Following this, it is crucial to inform your supervisor about the incident, and depending on the severity, you may need to visit the emergency room.
According to safety guidelines, knowing where specific safety equipment like the eyewash station is located is essential (2. Know where specific safety equipment is located). This equipment is designed to provide immediate decontamination of the skin and eyes in the case of accidental exposure to hazardous substances. After immediate decontamination, referring to the Safety Data Sheet (SDS) for further instructions could be necessary, but this comes only after you have washed the area and mitigated immediate danger to health.
Remember, the Safety Data Sheets contain important information on handling spills, exposures, and other accidents and can be very helpful, but should not take precedence over immediate decontamination.
