What is the Basic Classification of Clean Room Coveralls?

Clean Room Coveralls are majorly classified into six main categories, which are discussed below:

Gas Tight Class

Gas-tight classes, also known as Type 1 coveralls, provide maximum protection from workplace hazards.

These suits are fully packed, offering maximum protection to the wearer against contamination. They block the entry of all chemical contaminants regardless of their state. This includes preventing the entry of solid, liquid, and gaseous particles.

Non-Gas Tight Class

The non-gas tight class, also referred to as Type 2 coveralls, offers protection against particular contaminants. These suits are commonly used in applications involving high hazard risk.

They block the entry of all only limited contaminants. These include liquid, dust, and vapour particles.

Protection Against Liquid

This class protects against liquids and is called the type 3 coveralls. The unique property of this type is that it can withstand high-pressure strong liquid jets.

These suits are first tested by exposing them to strong liquid-blasted jets. Sensitive areas of the suit like zip fastenings and seam joints are kept the main target sites in this test.

Protection Against Liquid Spray

Protection against liquid spray class, also referred to as Type 4 coveralls, protects the wearer against liquids and liquid spray saturation.

These suits are also passed through a pressure strong liquid jet test, but the pressure is kept low with constant rotation. The suit is then allowed to saturate.

Protection Against Airborne Particles

Protection against airborne particles class known as Type 5 coveralls offers protection against dry and dust particles. These suits are tested by exposing them to a dust-filled spray cabin while having the wearer run on the treadmill.

The inward leakage is then counted by the particle counters present inside the coverall. The number of dust particles entering the suit is termed inward leakage.

Protection Against Liquid Chemical Splash

Protection against liquid chemical splash class, also called the Type 6 coveralls, offers protection against splashes and light spray.

These suits are tested by subjecting them to a light liquid spray without accumulating on the suit. During this test, the wearer is allowed to rotate constantly.

What are the Multiple Types of Clean Room Coveralls?

There are different types of Clean Room Coveralls available for multiple applications. Each type has its unique features making it suitable for a particular process. Some most common types are briefly discussed below:

Standard Protective Coveralls

This type of coverall consists of a basic protective layer that offers protection against various substances. These substances include dirt, stains, pollution as well as water splashes.

These coveralls have application in tasks where the essential purpose is to keep the clothes clean.

Fire Resistant Coveralls

Fire-resistant coveralls, also abbreviated as FR coveralls, have applications in tasks involving extreme heat. The best example is the work of firefighters.

The primary purpose of this coverall is to offer protection to the wearer against chemicals and potential burns. But what you must consider is that it is not entirely fireproof and may allow some heat to reach the wearer.

Waterproof Coveralls

As the name clearly says, waterproof coveralls have good water-resistant characteristics. It keeps the wearer dry by protecting him from water and moisture. Thus these coveralls are the best fit when wearing humid and wet conditions.

One-Time Use (Disposable) Coveralls

The safest type for Clean Room Coveralls is the one-time-use disposable Clean Room Coveralls type. It has no storage and maintenance demands.

You just have to use it once and discard it after that. This reduces the possibility of contamination by germs or bacteria. It is easily available and affordable also. Because of its overall hygiene and cleanliness, it is the highest safety rating.

Electric Resistant Coveralls

Workers working in electric companies usually use these electric-resistant coveralls. They are the people who have to deal with work-related electrical lines that are connected to telephone poles. Workers working with grids and electrical panels may also use these coveralls.

High Visibility

High visibility coverall is the perfect fit for construction and traffic control. Greater visibility is required to limit dangerous situations when working on the construction site. It has pre-installed light reflectors making them bright and shiny even in the dark.

What are the Necessary Features of the Synthetic Material Used in the Making Clean Room Coveralls?

The synthetic material used to make Clean Room Coveralls must possess the following necessary features to ensure maximum efficiency and guaranteed protection.

• The liquid shielding enables you to avoid any splashes of chemicals or reagents falling on your body directly. These splashes can be harmful and corrosive.
• These materials show minimum shedding so that there is no contamination from shredded particles from the coverall material itself.
• It shall be breathable and comfortable to wear. As it needs to be worn for long hours, any increase in temperature can lead to profuse sweating. It just not only makes it uncomfortable and wet but also compromises the efficiency of protection.
• The material used must be lightweight so that the user does not feel an additional burden.
• The selected material shall be appropriate for all classes of clean rooms.
• It shall be a non-linting material to avoid contamination of the environment.

What are the Different Materials Used in the Synthesis of Clean Room Coveralls?

A variety of various materials are used to manufacture coveralls. These materials possess some excellent shielding properties to keep safe from harm.

Any material that allows the harmful matter to enter into the coverall must not be used, and for instance, fabric has openings in it. That’s why knitted fabric must be avoided.

Fabric with no gaps is considered more appropriate because it is composed of closely packed material. Non-knitted fabric is preferred for this purpose.

Polypropylene

Although these coveralls are made from a non-knitted fabric, they can’t serve as a barrier against the harmful effects on the environment.

The reason is that their material structure is not closely packed enough to leave any gap in the fabric. Therefore the user is not protected from harmful environments.

Propylene coveralls are more desirable to be used in environments where the individual or its clothes are only exposed to non-harmful materials.

Spunbond-Meltblown-Spunbond (SMS)

This type of coverall is composed of 3 layers made up of polypropylene fabric. The outermost layer gives physical protection.

Then the second layer is known to have barrier properties because it’s manufactured by melting down polypropylene fibres to gain a denser structure.

The protective layer allows no harmful particles and solid material to pass through it. All such qualities make SMS suits quite useful and repairable with excellent protection.

Microporous Film Laminate (MPFL)

The third type of material used to manufacture coveralls is MPFL. This is a double-layered fabric.

The outer layer is composed of microporous polyethylene film attached to the inner layer of spun-bond polypropylene.

The outer layer is exposed to the physical environment, altering its properties. That is why the quality of protection can be decreased. Also, this layer consists of a film possessing non-constant potential, which makes it less reliable for the filtration process.

Microporous Film Laminate Clean Room Coveralls

What are the Steps to Keep in Mind While Wearing Clean Room Coveralls?

To remain protected from harmful working environments, it is necessary to wear the coverall properly.

You can’t keep yourself protected if it’s not worn correctly. To make sure complete efficiency of coverall following procedure must be followed:

• Carefully check the Clean Room Coveralls for any kind of flaws or physical damage, for example, rip ups or shredded parts. If you find any fault in the coverall, replace it instead of wearing it.
• If you are wearing any jewellery, remove it to contact the suit and tear it up.
• Take out the coverall from the clean room garment storage cabinet and wear it. Make sure it fits you properly, wrapping the wrists and ankles.
• If it consists of a headpiece, it must not be loose and cover the head entirely with a provided hood.
• Note that first, you try the coverall and practice the actions and motions you do after wearing it.
• It is necessary to correct any kind of fault in size if you aren’t comfortable moving in it.
• Select one size bigger to avoid any kind of inconvenience which may occur accidentally due to too many fit clothes.
• To avoid gaps between the arms cuff and gloves, use tape to cover the area adequately.
• In the same way, there must be no space left between leg cuffs and footwear.
• Carefully use the coverall in the workplace to avoid accidental damage to the suit because such damages can reduce the quality and working performance of the coverall, for example, hot liquids or shard surfaces.
