The background color used from the source to the outlets of a nitrous oxide medical gas system is blue. This is the standard color coding for nitrous oxide cylinders and pipelines in medical gas pipeline systems12. The color coding helps to identify the gas type and prevent accidental misconnections or cross-contamination3. The color coding also indicates the pressure and flow characteristics of the gas system4. References:

Hazardous waste

The correct answer is C. Environmental Protection Agency (EPA) standards require solid waste be treated as hazardous if it is a listed waste and/or meets the characteristics prescribed by the standard for toxicity, reactivity, corrosivity, andignitability.A listed waste is a waste that appears on one of the four lists of hazardous wastes in the Code ofFederal Regulations (CFR) part 261 subpart D1.A characteristic waste is a waste that exhibits one or more of the following traits: toxicity, reactivity, corrosivity, or ignitability2. Toxicity is the ability of a waste to leach harmful chemicals into the environment. Reactivity is the tendency of a waste to undergo violent chemical reactions or generate toxic gases. Corrosivity is the property of a waste to corrode metals or damage living tissues.Ignitability is the capacity of a waste to catch fire under certain conditions2.These characteristics are defined by specific tests and criteria in the CFR part 261 subpart C3.The EPA standards for hazardous waste are based on the Resource Conservation and Recovery Act (RCRA), which is the federal law that regulates the management of solid and hazardous waste in the United States4.

Fire pump

Explore

A multistage centrifugal fire pump is defined as having two or more impellers on one shaft as a single unit. A multistage centrifugal pump is a type of centrifugal pump that uses multiple impellers to increase the pressure and flow of water.Each impeller acts like a single-stage pump within a chain of pumps, and the water passes through each impeller in series, gaining pressure and velocity at each stage1.A multistage centrifugal fire pump is used to provide high-pressure water for fire protection systems, especially in high-rise buildings or large industrial facilities2.A multistage centrifugal fire pump can be driven by an electric motor, a diesel engine, or a steam turbine3.References:
