Quiz 5: Safety and First Aid


There is no answer for this question

Many chemicals are required in the health care amenities, mainly in the departments of the clinical laboratory. As chemicals may exhibit physical or health threats, the Hazard Communication Standard (HCS) has been revised in the health care facilities. Principles for hazardous reagents and chemicals are being changed for the purpose of global harmonization. This signifies the global development of the dangerous classification of constituents, and transportation guidelines, which are constant among all the nations. The CDC (Centers for Disease Control and Prevention) is a federal agency of the United States, under the Department of Human and Health Services. Its prime aim is to safeguard public safety and health, by prevention and control of injury, disease, and disability in the United States and globally. The USFDA (United States Food and Drug Administration) is the federal agency, under the Department of Human and Health Services. It supervises and controls tobacco products, food safety, vaccines, dietary supplements, biopharmaceuticals, medical devices, and veterinary products. The CLSI (Clinical and Laboratory Standards Institute) is a membership-supported, volunteer driven, not for profit, organization of standards development. CLSI encourages the application and development of voluntary laboratory guidelines and consensus standards within the health care communal. Its aim is to develop laboratory and clinical methods, and encourage their global use. Hence, the options a, b and d are incorrect. The NFPA (National Fire Protection Association) is a trade association of the United States, even though with some international members, which maintains and creates copyrighted and private standards, and codes for adoption and usage, by local governments. The NFPA developed a marking scheme for dangerous chemicals, which is constantly used in health care amenities. Hence, the correct answer is option img .

The constituents of fire are oxygen, fuel, and heat, plus the essential chain reaction. Three general categorizations of fires have been adopted by the NFPA (National Fire Protection Association). Class A fires need a pressurized water extinguisher, or an ABC extinguisher for paper, wood, trash, and clothing. Class B fires require a carbon dioxide extinguisher or an ABC extinguisher for grease, liquid, and chemical fires. A class C fire refers to electrical fires, in which a halon, carbon dioxide, or ABC extinguisher can be used. The ABC extinguisher is the one used in most of the health care amenities. PASS refers to a technique, which is used to discharge the extinguisher within its efficient array. It stands for pull, aim, squeeze, and sweep. Most of the fire extinguishers functions, by using the following PASS technique: 1. Pull: The pin is pulled, which also breakdowns the tamper seal. 2. Aim: One should aim low, by directing the nozzle of the extinguisher towards the fire base. 3. Squeeze: The handle of the extinguisher is squeezed to discharge the extinguishing material. 4. Sweep: The last step is to sweep from side to side at the fire base until it seems to be out. If the fire starts again, then replication of steps 2 to 4 is done.
