The purpose of moisture barriers in structural firefighting personal protective equipment is to protect firefighters from water, blood, bodily fluids, and other liquids. These barriers are impermeable to liquids, preventing them from soaking into the clothing and reaching the firefighter's skin. This helps to keep firefighters dry and minimize the risk of exposure to hazardous substances.
The moisture barrier found in firefighting gear acts to protect from the effects of steam. Firefighting introduces a massive amount of water into some very hot spaces and surfaces, and the resulting steam generated would quickly par - boil a firefighter if not for the gear we wear. Even with the gear, you can really feel it when the 300 degree floor level heat in a house fire changes instantly from dry heat to a sauna on steroids when you open that nozzle.
Personal protective equipment for eyes, face, head, and extremities, protective clothing, respiratory devices, and protective shields and barriers.
Time barriers, geographic barriers, cost barriers, structural barriers.
Personal Protective Equipment (PPE) is specialized clothing or equipment worn by a caregiver for protection against infectious materials. PPE Includes gloves, gowns, shoe covers, head covers, masks, respirators, eye protection, face shields, and goggles.

There are many forms of birth control out there, but if you're looking for physical barriers there's really only one of two things: condoms, or diaphragms. There are older forms of physical barriers, but many of them are not as protective. In addition to these barriers you can use some kind of spermicide, which comes in foam or lube form, but can be messy.
Three distinct types of barriers are:structural barriers,material barriers, andmental barriers.STRUCTURAL BARRIERS:A physical/structural barrier refers to an object or structure, such as a brick wall or boulder, which impedes and prevents the movement or progress of another object in its intended direction. Structural barriers may also often provide one or more objects protection from the dangerous and destructive force, influence or effect of another object. For example, The Great Barrier Reef, located in the Coral Sea, off the coast of Queensland in north-east Australia, is an expansive (133,000 sq. mi.) saltwater ecosystem built upon billions of nearly immobile living ocean organisms, known as coral polyps. Coral reefs are often referred to as "barrier reefs;" because, as living biological structures, they provide coastal land environments physical protection against strong ocean currents and waves by slowing down the flow of seawater before it reaches shore.MATERIAL BARRIERS:Likewise, a physical/material barrier refers to any substantial action, phenomenon, force, influence or object which impedes and prevents any other action, phenomenon, force, influence or object from proceeding toward, arriving at or achieving an intended result. In sharp contrast to protective structural barriers, many material barriers are often considered to have a detrimental effect on the otherwise beneficial forward direction of an object or action toward development, progress and positive change. For instance, "'trade barriers,' [...] a general term that describes any government policy or regulation that restricts international trade," are usually physical or material in nature. Such barriers may take numerous concrete & tangible forms, including tariffs, import/export licenses & quotas, subsidies, voluntary restraints, local content requirements, and embargo.Most trade barriers are founded on one common principle: an imposition of cost on trade which in turn increases the price of traded products. Barriers to international trade are often criticized for the negative impact they have on the developing world; where as, "in theory, free trade involves the removal of all such barriers, except perhaps those considered necessary for health and national security," and has often been touted a panacea for global economic crisis and poverty.MENTAL BARRIERS:In addition to structural and material barriers between objects and/or actions, one may often experience mental barriers; which, by contrast, are defined as immaterial, intangible and abstract psycho-ideological and/or spiritual impediments to the achievement of one's actions or to the construction and conclusion of one's thoughts. Such cerebral or emotional barriers may be either protective or detrimental in nature. More often than not, human thought and action may be either challenged or encouraged by both physical (i.e., structural & material) and mental barriers. Let us consider barriers to listening as an example. Physical barriers to effective listening "include hearing impairments, noisy surroundings, speaker's appearance, speaker's mannerisms, and lag time," while mental barriers that may impede, prevent or hamper successful listening may "include inattention, prejudgment, frame of reference, closed-mindedness, and pseudo-listening."A quick comparison of this dichotomous binary grouping of barriers to listening does indeed expose an obvious opposition between two distinct types of barriers: tangible vs. intangible, material vs. cerebral, and/or physical vs. mental. The barriers cataloged in this example, however, are not protective in nature; they are instead solely considered obstacles which negatively impact the listening process.There are also social barriers,which include religion, where and what you work at, where you live or plan to live, money, all of which should be immaterial to who you know or what you know
