In a computer room where ordinary combustibles are present, the most suitable type of extinguisher would be specifically one that does not conduct electricity and can effectively extinguish potential fires that could arise from electrical equipment or ordinary combustibles. CO2 extinguishers are particularly advantageous because they extinguish fires by displacing oxygen, which is vital for combustion, and they do not leave any residue that could damage sensitive electronic equipment, making them ideal for environments with computers.

While water extinguishers can effectively combat ordinary combustibles, they pose a risk of electrical shock in an area containing electronic equipment. Similarly, foam extinguishers are designed primarily for flammable liquids and can also leave residues that may harm electronic components. Dry chemical extinguishers are effective for a variety of fire classes but can create a mess and damage equipment, unlike CO2 extinguishers which maintain the integrity of the sensitive technology in a computer room. Thus, the choice of a CO2 extinguisher in this scenario is optimal for safety and equipment protection.
