Bromine is a chemical element that is one of 118 elements that appear on the periodic table. Bromine’s appearance in liquid form (in an ambient temperature) is a deep-red, oily liquid. As it evaporates from an ambient state into a gas, a similar-coloured gas is produced. Bromine is toxic to humans and hazardous to health. If you experience a spill or accident we strongly recommend you hire a professional bromine cleanup service immediately.

Bromine Poisoning

The vapours are harmful in both a liquid state and vapor state; especially if the element has been inhaled or exposed to the skin. The element irritates the skin and tissues that it comes into direct contact with.

You can assess whether bromine poisoning depending on how much bromine the individual has been exposed to and the duration of time they have been exposed for. Certain factors should also be considered for the individual who has been exposed including any existing medical health issues alongside considering their age.
