The four emergencies an office should be equipped to handle are: Sudden Cardiac Arrest, Seizures, asthma attacks and allergic reactions.
Natural emergencies are emergencies such as symptoms of a disease or sickness, whereas a man-made one is something like trauma such as a car accident or burns.
the main reason why restraunts have seperate areas for smokers is because they dont want others getting lung cancer, or someone with asthma getting an asthma attack
