What compound can be used to raise free available chlorine levels quickly in emergencies?

calcium hypochlorite
dichlor
sodium bicarb
trichlor

The correct answer is: calcium hypochlorite

Calcium hypochlorite is the best option for raising free available chlorine levels quickly in emergencies because it is a powerful and fast-acting compound that can increase chlorine levels within minutes. Sodium bicarbonate, also known as baking soda, is not an effective choice for increasing chlorine levels as it is used to raise alkalinity levels. Dichlor and trichlor are slow-dissolving forms of chlorine and are not suitable for emergency situations where rapid increase in chlorine levels is needed.
