P.A.S.S. stands for squeeze, sweep, press, and aim. This abbreviation is frequently used to help recall how to use a fire extinguisher. "Press" means to push the handle to start the extinguisher; "aim" means to aim the nozzle at the fire's base; "squeeze" means to squeeze the handle to release the extinguishing chemical; and "sweep" means to move the nozzle side to side to cover the whole area of the fire.
Paper, wood, and other common combustible items are involved in class A fires. Class B fires are caused by combustible gases and liquids, such as propane and gasoline. Electrical equipment is involved in class C fires. The components used in Class A, B, and C fires are accurately identified by the response "trash, flammable liquid, electrical".
Because gasoline is a flammable liquid, it is categorized as a Class B fire. Class B fires are caused by combustible liquids or gases, like natural gas, propane, oil, and gasoline. Fire extinguishers made especially for flammable liquid flames, including foam or carbon dioxide extinguishers, can be used to put out these fires.
According to the statement, Fireguards should routinely check every section of the work site every hour from 4 p.m. to midnight every day. This is crucial for maintaining the job site's safety and security since it enables the Fireguard to quickly detect and handle any possible fire risks or hazards. Frequent inspections also aid in the detection of any illegal activity or safety protocol infractions. For this reason, it is essential that Fireguard spend the allotted time walking the whole job site every hour.
A fireguard never approaches a fire from the downwind side since doing so may potentially cause them to be consumed by smoke and flames. They would be exposed to the full force of the fire if they approached it from the downwind side, which would make it more difficult to successfully control or put out the fire. Consequently, a fireguard is less likely to be trapped in the path of the fire if they approach a fire upwind, when the wind is blowing away from the fire.
Since cloth is a common combustible material that ignites and sustains fires easily, it is classified as a Class A fire. Commonly combustible materials like wood, paper, cloth, and plastics are involved in class A fires. After burning, these fires usually leave ash and char behind. Fires that are classed as electrical, metal, or flammable liquids are categorized under Class C, Class D, and Class B, respectively.
Class C fires involve electrified electrical equipment, while Class B fires involve combustible liquids including gasoline, oil, and grease. Since wood and metal are not stated in the question specifically, it cannot be deduced that they are involved in Class B and C fires. Thus, "No" is the appropriate response.
