A business or industry should not only have a first aid kit because they are required to do so by law, but rather because they believe how important it is to take care of their employees.
In the event of an injury, someone trained to administer it should carry out first aid. Items in the first aid kit such as bandages or gauze dressings can be used over cuts.
A first aid kit is also useful in the event of a foreign object or chemical entering the eyes. They will usually contain an eye wash bottle to rinse the eyes.
The third reason why it is important to have a first aid kit is because they enable someone who is injured, to be quickly treated with basic first aid, before they can be properly treated at the local hospital. Therefore in an emergency situation, it is recommended someone knows where the nearest first aid kit is located and how to use the contents within it.
