Question
f a person working in a lab gets sprayed with concentrated sulfuric acid over a large area of their body, they should almost certainly wash IMMEDIATELY in a safety shower and call for help. Conversely, if a person spills 2 drops of 0.001 molar NaCl in water solution on the back of their hand, there is probably not an urgent need to drench the individual in a safety shower. Between these two extremes, there is an undefined "gray area" where an individual needs to decide the best course of action (i.e., should I use a safety shower, or will a brief rinse with water from the sink be sufficient?)
In a chemical accident situation, briefly describe what conditions you think would warrant the immediate use of a safety shower.
Explanation / Answer
The use of chemicals is very important to avoid dangerous situations like this in chemical laboratories. H2SO4 is a strong acid, so it will cause harmful effects by spraying or falling o body parts. So at that time itself pore more water or use a safety shower. A small sink cannot do anything, need to apply water flow for a longtime to avoid further injuries and to decrease the effect.
Salt is neutral solution, it will not cure the acid attack, always the better thing is use safety shower.
