Clear pipes are used for transporting solid objects, while conventional pipelines are used for fluids
Hospitals use a variety of different piping systems for various purposes. Some of the most common types include medical gas systems, pneumatic tube systems, and drainage systems.
Medical gas systems are an essential part of hospitals, providing life-sustaining gases such as oxygen and anesthesia gases to patients during surgery or in their rooms. These gases are piped at regulated pressures into the hospital building, with the oxygen measured and its pressure regulated before distribution. Medical gas systems are heavily scrutinized due to safety concerns, with hospitals hiring third-party inspectors to ensure they meet strict standards.
Pneumatic tube systems, on the other hand, are used for transporting solid objects and small packages quickly and conveniently within a local environment. In hospitals, these systems are often computer-controlled and used to deliver drugs, documents, specimens, blood samples, X-rays, and test results to and from laboratories and nurses' stations. They are particularly useful for time-sensitive packages that need to be analyzed or processed promptly.
Drainage systems in hospitals often utilize glass tubing due to its non-reactive nature to human "discharge" and the ease of retrieving accidentally fallen items without contamination. While glass tubing is expensive and heavy, it is suitable for drainage systems as an alternative to conventional plastic or metal piping, which can be corroded by certain chemicals.
Clear pipes are indeed used in hospitals, particularly in pneumatic tube systems for transporting solid objects, while conventional pipelines are typically used for fluid transport. These clear pipes offer advantages such as convenience, speed, and the ability to monitor the transported items. However, they may not always be practical for complex plumbing systems or in instances where exposure to sunlight or unpleasant visuals may be a concern. Overall, the choice of piping material and type depends on the specific application, regulations, and safety considerations within the hospital environment.

Glass pipes are used in drainage systems as they are non-reactive to human discharge
Glass pipes are used in hospital drainage systems as they are non-reactive to human discharge. While glass pipes are not a strict requirement in hospital drainage systems, the Canadian building code states that pipe materials must be non-reactive. Glass is an excellent choice for this application because it meets the non-reactivity requirement, but it is also expensive, heavy, fragile, and increasingly difficult for contractors to source. As a result, many healthcare facilities and laboratories now use fibre-reinforced polypropylene pipes, which are available in various colours, including light green or turquoise.
Glass is often used in acid waste lines in hospitals due to its non-reactivity. These pipes can be identified by the presence of purple dye from chemicals used in the lab. In addition to glass, plastics such as fibre-reinforced polypropylene are also used in acid waste lines. "Sapphire glass" is another type of glass used in labs for its transparency to visible and ultraviolet light, allowing for the recording of the absorbance spectrum of a chemical in solution.
The use of glass pipes in hospitals is not limited to drainage systems. Glass tubing is also used in pneumatic tube systems, which are used to transport small, time-sensitive packages, such as blood samples, drugs, documents, and specimens, within hospitals. These systems are computer-controlled and offer convenience and speed in local environments.
While glass pipes have their advantages in specific applications, other materials are considered for general plumbing in hospitals. For example, PVC pipes are used in some hospitals, but they must meet certain fire safety standards to prevent the release of toxic fumes in the event of a fire. OSHPD-regulated healthcare buildings in California, for instance, have specific requirements for the types of pipes that can be used.
In summary, glass pipes are used in hospital drainage systems because they are non-reactive to human discharge, making them ideal for acid waste lines. However, glass pipes have drawbacks, including cost and fragility, leading to the adoption of alternative materials, such as fibre-reinforced polypropylene, in many healthcare facilities.

Pipes in hospitals are regulated by fire codes to prevent the release of toxic fumes
Hospitals have a wide range of piping systems, from medical gas pipes to plumbing pipes and pneumatic tube transport systems. Medical gas systems are used to pump gases such as oxygen and anaesthesia gases to patients in surgery or their rooms. These systems are heavily regulated to ensure patient safety and prevent incidents like the medical gas cross-connection deaths that occurred in 1973 at a hospital in Canada. The regulations include requirements for shut-off valves, pressure-sensing alarms, and monitoring of supply and pressure levels.
Plumbing pipes in hospitals are subject to fire codes to prevent the release of toxic fumes in the event of a fire. For example, in Canada, plumbing pipes must meet specific flame spread and smoke development ratings. While some older hospitals may use glass pipes due to their non-reactivity, modern hospitals often use fibre-reinforced polypropylene or other non-reactive materials that meet fire safety standards.
To comply with fire codes, hospitals use a variety of pipe materials that are non-combustible or have low flame spread and smoke development ratings. For example, copper pipes are preferred in OSHPD-regulated buildings in California. Additionally, pipes made of plastic or polyvinyl chloride (PVC) must be wrapped if exposed in ceilings or open walls to prevent them from burning.
The fire codes that regulate pipes in hospitals are an essential aspect of ensuring patient and staff safety. By preventing the release of toxic fumes, these regulations help protect people's health and well-being in the event of a fire. While some question the effectiveness of these measures, considering the potential consequences of a fire in a healthcare setting, it is crucial to adhere to these fire safety standards.

Plastic pipes are wrapped to prevent them from burning
Hospitals use a variety of piping materials, including glass, copper, and plastic. Plastic pipes in hospitals are often wrapped to prevent them from burning and releasing toxic fumes in the event of a fire. This is a requirement in fire codes for hospitals, which differ from those for other commercial buildings.
While plastic pipes are convenient and widely used, they can catch fire and melt relatively easily, releasing toxic fumes. To mitigate this risk, hospitals employ various strategies, including using alternative materials like glass or copper pipes, which are non-reactive and less flammable, or wrapping plastic pipes with fire-resistant materials.
One common method to prevent plastic pipes from burning is to wrap them with fire-rated pipe wrap. This wrap consists of a graphite-based reactive intumescent strip that reacts to heat, closing any openings created by softening or melting plastic pipes. This type of wrap can be installed around the pipes and secured with self-adhesive tabs, providing an additional layer of protection.
Additionally, fire sleeves, pipe collars, and other fire-stopping materials are designed to expand when exposed to heat, sealing gaps and preventing the spread of fire. These solutions are crucial for maintaining the integrity of compartments within a building, ensuring that fire and smoke are contained. It is important to note that the choice of fire-stopping components depends on the specific building materials and circumstances.
In some cases, pipes may be installed in a way that meets building codes and engineered designs, ensuring safety without the need for additional wrapping. However, wrapping plastic pipes with insulation or fire-resistant materials provides an extra layer of protection, helping to prevent the spread of fire and keeping occupants safe.

Medical gas systems are used to pump gases such as oxygen to patients
Medical gas systems are subject to multiple layers of restrictions and instructions to ensure their proper, safe, and legal usage. The scrutiny surrounding medicinal gas systems means that hospitals often hire third-party inspectors annually to check every element of their system. These inspectors confirm that the systems are functional and meet the required standards, ensuring the safety of patients and staff.
In addition to oxygen, medical gas systems may also include anesthesia gases used in surgery. These gases are carefully monitored to prevent medical gas-related deaths, which have occurred in the past. Codes have been implemented to prevent such incidents, requiring third-party verification and system installation certification.
While not part of a regular inspection, the sensors on the pipeline can and should be tested. This testing is done by certified experts with advance warning, as it may interrupt the gas flow. The alarms in the system are crucial, as they alert staff if the supply drops. Modern hospital rooms typically have duplicate sets of oxygen outlets and vacuum inlets to ensure a constant supply of medical gases.
Hospitals also utilize pneumatic tube systems, or capsule pipelines, to transport small, time-sensitive packages, such as blood samples, drugs, documents, and specimens to and from laboratories and nurses' stations. These systems use compressed air or partial vacuum to propel cylindrical containers through a network of tubes, providing convenience and speed in local environments.
