Well, sodium hydroxide is caustic soda....

Explanation:

And I have talked about the hazards of handling caustic and its aqueous solutions here.

And chlorine is an asphyxiating gas....the which at one stage was used as a war gas. And of course the use of ANY gas in the laboratory poses special hazards....not only are the gases dangerous, but the gas cylinders themselves constitute a real and present hazard....all gas cylinders must be securely chained to a wall, and properly regulated...

And liquid ammonia is a room temperature gas, the which pen and inks VERY badly...an ammonia cylinder is usually connected to a dry-ice acetone condenser the which condenses the ammonia into a liquid. The condenser is at a temperature of #-78# #""^@C#, the which is capable of condensing the ammonia, whose normal boiling point is #-33.3# #""^@C#.

Sodium Hydroxide is a strong base.
Chlorine gas is strong oxidizing agent.
liquid ammonia is concentrated medium base but as a gas or liquid is very penetrating.

Explanation:

Sodium Hydroxide is a very strong base. Skin contact can "dissolve" the skin, causing severe chemical burns. The liquid in the eyes can cause permeant blindness unless immediately treated.
Sodium Hydroxide is found in drain cleaners. The heat and gases produced by the chemical reactions with Sodium Hydroxide can cause the dangerous liquid to be "blown" back up into people's faces and eyes. Gloves and protective glasses should also be used when handling drain cleaners or other mixtures that contain Sodium Hydroxide.

Chlorine gas is a very strong oxidizing agent. The toxic Mustard gas outlawed after World War I was Chlorine gas. Breathing Chlorine gas will "dissolve" the alveoli in the lungs. The ruptured tissues will cause internal bleeding in the lungs, throat and nose.
Chlorine gas is used to control bacteria and algae growth in pools,
Care must be taken not to breath the gas.

Liquid chlorine such as bleach can also release chlorine gas. Bleach should never be used in a closed space. Also the chlorine in Bleach can also reach with ammonia to produce poisonous Ammonium Chloride gas. Do not use windex or other cleaners that contain ammonium with liquid chlorine bleach.
