CO2 fire extinguisher.<\/p>\n<p>Water is a good conductor of electricity, so it can flow through the water and reach the electrical source, which can cause a shock or electrocution. Carbon tetrachloride is a toxic gas that can be harmful to breathe in. Foam type fire extinguishers are not effective for electrical fires. CO2 fire extinguishers are non-conductive and do not produce harmful gases, so they are the safest option for extinguishing electrical fires.<\/p>\n<p>Here is a more detailed explanation of each option:<\/p>\n<ul>\n<li>Water: Water is a good conductor of electricity, so it can flow through the water and reach the electrical source, which can cause a shock or electrocution. Additionally, water can create steam when it comes into contact with a hot electrical fire, which can spread the fire.<\/li>\n<li>Carbon tetrachloride: Carbon tetrachloride is a toxic gas that can be harmful to breathe in. It can also damage the ozone layer.<\/li>\n<li>Foam type fire extinguishers: Foam type fire extinguishers are not effective for electrical fires because the foam can conduct electricity.<\/li>\n<li>CO2 fire extinguishers: CO2 fire extinguishers are non-conductive and do not produce harmful gases, so they are the safest option for extinguishing electrical fires. CO2 fire extinguishers work by displacing the oxygen in the air, which suffocates the fire.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Water&#8221; option2=&#8221;Carbon tetrachloride fire extinguisher&#8221;
