About Hand Protection

A good subtitle

The Glove is the only protective layer between your hands and what you work with, so choose the right one!

Here you can read about the selection of proper gloves for your work and how they protect the skin. Follow these 3 easy steps so you know what to do (do not take more than 5 minutes).

Step 1. Considerations for glove selection

Before one can determine the type of gloves to be used must ask themselves two questions:

What should the Glove protect against?

  • Chemicals?

  • Cold or heat?

  • Cut and tear?

  • Wear and tear?

  • Used for food handling?

Which features should the Glove have?

  • A good and reliable grip on tools, equipment and the like?

  • Allergy friendly?

  • Anti Vibration?

  • Reduce the risk of electrostatic discharge (ESD)?

Step 2. Determine the glove type

Overall gloves are divided into work gloves, chemical gloves and food approved gloves.


Work gloves / assembly gloves

Work gloves, also called assembly gloves, protects against (depending on the glove) mechanical effects and can be:

  • Abrasion, puncture, vibration, heat and cold.

Work gloves are typically made of leather, fur or cotton, but can also be made of plastics such as PVC and Nitrile.


Important to note on work gloves!

  1. Work gloves normally does not protect against chemicals. However, although there are work gloves lined with rubber or plastic coating Arbejdshandsker beskytter normalt ikke mod kemikalier.

  2. It can provide a work glove some of the chemical glove properties, but protects most often not sufficiently well to chemicals.

  3. It has been generally known that gloves made of leather often has better abrasion resistance than gloves made of plastic, but in many cases today, there are gloves made of plastic which is as durable.

  4. Moreover, they often a lot of other good properties as anti-static, anti-vibration or extremely good gripping ability.

Chemical gloves

Chemical protective gloves are gloves that are able to withstand the chemicals (depending on the glove).

Some chemical gloves can withstand multiple chemicals in less time or longer (see breakthrough time), where the other gloves are only able to withstand a single chemical.

They are most often used in contexts where work with liquids or solids that can damage your skin and your health. Eg. if you work with acids and alkalis, oils, esters and ketones, chlorinated and aromatic hydrocarbons)


The material's impact

Chemical protective gloves are available in many different materials, and as a result of the material can cause glove some properties and has great influence on its influences from a chemical.

Eg. allergy friendly, good grip, better abrasion resistance than other chemical gloves made of other materials, etc.

The most common materials for chemical gloves are: natural latex (rubber), nitrile and PVC.

The slightly more rare, but also more expensive gloves in butyl rubber, Vitron and PVA. The glove material is very crucial to how well it resists impacts from a chemical.

Below you can read more about the usual glove materials and the chemical groups most frequently resist.

Chemical groupsGlove material
Chlorinated and aromatic hydrocarbons for example. dichloroethane, toluene, xylenePVA
Flourpolymer
Aliphatic hydrocarbons such. heptanePVA
Flourpolymer
Neoprene
Nitrile
Polyethylen
Alcohol and glycolsButyl
Natural rubber
Neoprene
Nitrile
Polyethylen

Important to note about chemical gloves!

  1. There is no glove that can resist all chemicals.

  2. There are gloves that can resist more chemicals at the same time, however, one must be aware that they often do not do it nearly as well as a glove that is designed to withstand a single chemical.

  3. Chemical protective gloves are unlike work gloves usually made to meet very specific needs (eg. Food grade gloves, disposable glove mm.) And should therefore also be used according to the directions and not for other purposes.

  4. It is most often seen that PVA gloves can be used for many organic solvents, but you must be careful for they do not tolerate water.

  5. If the item you are working with contains several substances (even small amounts of a substance) that can penetrate a particular glove material - it may seem like addictive substance and lead other substances through. Even if the gloves have good protection

Hands - an important tool

Your hands are an important tool in daily life so it goes unsaid that they are an important tool from the very precision mechanical and chemical to hard abrasive work. Not using the right glove, your skin can become irritated, you run the risk of developing eczema and in bad cases make your hands incapacitated.

"Gloves have over the last 20 - 30 years undergone a rapid development, and today there are gloves that protect against almost any risk. Producers are also used many resources to make the gloves more comfortable, so that the excuses for failing to protect his hands and arms gradually dwindle.

It attracted the attention of chemicals and how they can be absorbed through the skin with disastrous consequences, has driven the development of suitable gloves up. Prices are new materials in use, but most importantly in this context it is that producers can now inform much better about how long a glove provides protection against a specific chemical or other risks. Where previously spoke of a glove is resistance to a chemical that talk today about how long the glove protects the wearer, with the obvious difference that it is the person who will be using the glove, which is set in the center, and not the glove material physical nature. As for protection against a specific chemical, the consumer is necessarily continue to seek guidance from the supplier. Via our chemistry guide you well on your way.

Where the employer has assessed the individual workplace and must provide suitable gloves available where the risk has been unable to be eliminated, there are now a more objective selection basis. The same is of course applicable in the other glove categories such. protection against mechanical stress, heat, cold, etc. "

Storage of gloves

Gloves must be kept clean, dry, like dark and protected from sunlight. Avoid temperatures above 30 ° C. Sterile gloves must also be kept low dust in storage for sterile articles.

Gloves should be placed at a good distance from washbasin facilities. Gloves should not be stored, so they are exposed to spray or splash with blood, secretions and excretions. Opened packaging must be handled and stored so that the contents do not become contaminated.

General guidelines for the use of gloves

To be able to work most safely, there are some general procedures that must be followed.

  • Chemical protective gloves must be frequently changed between each object / patient and after each procedure / task at the same workplace / patient.

  • Gloves should not be washed or disinfected and used through to the second procedure.

  • Watches, rings, bracelets and other jewelry may not be worn on the hands or forearms, even when using gloves.

  • Cream or lotion should not be used immediately before gloves made of. When using hand alcohol skin must be completely dry before gloves made of.

  • The gloves must be replaced immediately when there is a hole on the glove.

  • The skin's ability to repair damage is reduced if the skin is trapped for a long time in a dense glove. To prevent injuries, gloves be used only as long as necessary.

  • By moist skin you can use cotton gloves under the gloves.

  • For recurring skin problems, eczema or suspected allergy can contact your local health nurses.

  • After using discarded glove in accordance with applicable regulations for waste management. Pay attention to special rules for working with carcinogens.

  • Hand wash or disinfection must always be performed by use of gloves, though the gloves looks intact out because the hands can be contaminated despite that use gloves.

  • There is an amplification of the normal flora of the skin in the warm humid environment under the gloves.

  • There are microscopic holes (pinholes) in a certain percentage of the gloves.

  • Gloves, the expiry date shall not be used. Therefore, old deliveries used before new is used.

Glove Allergy

Use of gloves can for some cause allergies, and here are 2 different forms:

  1. Latex Allergy with immediate response.

  2. Contact allergy with delayed reaction.

Diagnosis, treatment and counseling of possible latex or contact allergy requires dermatological specialist examination. Seek medical attention!


Latex gloves

Latex Gloves made of latex sap that is tapped from rubber trees and containing 1-2% latex proteins. Some of these proteins have allergenic properties. During the manufacturing process the gloves are rinsed, so that most latex allergens are washed out, but some may remain in the finished product.

In the case of latex allergy symptoms occur within minutes after contact with the latex rubber. Symptoms include hives, edema and intense itching on the skin that have been in contact with latex glove. Symptoms usually fades within a few hours. In very rare cases there may be a risk of generalized symptoms (anaphylactic reactions).

If you've been diagnosed latex allergy, for some persons, performing cross-reactions with proteins in certain foods, that is, that by consuming a variety of fruits and vegetables (banana, avocado, kiwi, sweet chestnut tree, papaya, figs, potatoes and tomatoes) may have symptoms, especially from the oral cavity. Risk of developing latex allergies are reduced by using the powder-free gloves and latex gloves with documented low levels of latex allergens.


Contact allergy

(allergy to rubber chemicals)

During the manufacturing of gloves regardless of material (latex, nitrile, neoprene, etc.) are used adjuvants (chemicals - Accelerators and antioxidants), which can cause allergies. The majority of the excipients will be used during the production process. After production takes a rinse, where much of the remaining chemicals flushed away, but there may still be small residue remains. The better producer wash the gloves after production the less likely you are to develop contact allergy.

Symptoms in mild cases, itching and slight redness at the back of the hand. Subsequently, there may be small red bumps, possibly. with blisters. Symptoms come six months to days of exposure and fades after several days to weeks.

For prolonged exposure developed chronic eczema with itchy, red, scaly patches of thickened skin. Such chronic eczema heal until several weeks after cessation of exposure.

The choice between sterile gloves vs. non sterile

Sterile gloves

Sterile gloves should be used where contamination of the area involved is a risk that must be eliminated. There are standards for disposable medical gloves and standards for protective gloves.


What are sterile examination gloves and when they are used?

A sterile examination glove is a medical glove, designed for medical examination and treatment of shorter duration. Sterile examination gloves are usually cheaper than surgical gloves.

Sterile examination gloves used in aseptic procedures in bed and study departments, for example sterile intermittent catheterization (SIK) and handling of centralvenekatetre.


What is surgical gloves?

A surgical glove is a sterile, anatomically shaped medical glove that is intended for surgery.

Surgical gloves used in all operations and interventions as well as in clean areas where specific dress code applies.

Surgical gloves are used to an antimicrobial barrier between the hands of the personnel and the patient's tissue. Handskeperforationer will occur more or less frequently depending on the type and duration as well as the user's function during the procedure.

Surgical gloves are also available as double gloves and indicator gloves. It is the type and duration as well as the user function that determines whether to use single or double gloves. The use of two pairs of gloves, that is, Double gloves, will reduce perforationsrisikoen. It is recommended that the inner glove is half a size larger than the outer glove.

There is a double glove system, light glove with a colored inner glove, where the perforations in the outer glove is clearly apparent. The system utilizes the light refraction changes when there is fluid between the two gloves.


The use of sterile protective gloves

Sterile gloves are used where there is a need for a sterile glove, which also protects against chemicals / drugs, for example, in the preparation of cytotoxic drugs or for the handling of the bone cement.


Requirements for sterility

Sterile medical devices must be CE marked and comply with the standard EN 556-1. For a product to be called sterile, it must undergo documented sterilization process. It follows that in practice there may exist revivifiable microorganisms, ie for every 1 million products may only be a propagation skilled microorganism. The requirements for validation and routine control of processes for sterilizing medical equipment is defined in EN 550, EN 552, EN 554th


Non-sterile gloves

(clean gloves)

Non-sterile gloves are also called clean gloves. A non-sterile gloves are used, which are not required. There are standards for disposable medical gloves and standards for protective gloves.


The use of sterile medical gloves

Non-sterile medical gloves used in the study, treatment and care, where there is a risk of contact with contaminated materials:

  • blood or secretions

  • saliva and vomiting

  • urine and feces

Moreover, by:

  • pouring medicine

  • food handling

  • by nicks, cuts or eczema on the hands

The use of non-sterile gloves

Non-sterile gloves are used where there is a risk of contact with chemicals, for example in laboratories, or certain drugs such as cancer chemotherapeutic agents and steroids.

Permeation times for gloves

Test for permeation times must be done according to the standard DS / EN 374-3.

In contact with chemicals, drugs, steroid creams, etc. hands should be protected well. Therefore, it is important to find the glove that is best suited for the purpose. This is done by examining whether there is a glove that is tested for just the chemical / product, there is a chance to get in touch with. If there is no breakthrough or chemical / the product passes quickly through the glove, the gloves should be generally changed by contact with the chemical / product and discarded after use.

It is very different how many chemicals, the individual gloves are tested for. When the supplier can get an overview of the chemicals / mixtures / products glove is tested for and what breakthrough time. The higher the penetration, the longer it takes before the chemical penetrates the glove. Test for the breakthrough time (374-3) is carried out at 23 ° C, but in practice, use gloves at a higher temperature (about 35 ° C). This means that the breakthrough time is reduced by about a factor of 3, i.e. actually penetrates the chemical quickly through the glove than the specified breakthrough.

Be aware that when working with spreads so true breakthrough times for the substances not necessarily. Example: A glove is tested for 3 chemicals as well as a mix of these three chemicals:

Chemical/productPermeation time in minutes
Acetonitril 100%3
Methanol 30%5-10
Ammoniak 25%53
Acetonitril 73,3% + Methanol 24,5% + Ammoniak 2,2%2,2

Test of products

What products can be tested for permeation times? This depends on what form the product are:

  • Liquid

  • Solid (powder, crystals, tablets)

  • Creams and ointments (including steroid creams)


Liquids

The vast majority of fluids can be tested for breakthrough times for either the DS / EN 374-3 or ASTM, F739. Unfortunately, it is far from all liquids tested, partly because used many different and partly because it is expensive to conduct these tests.


Solids (powder, crystals, tablets)

Can not yet tested according to the standards, but it is known that solids are generally very slow to penetrate the gloves. However, it is possible that some of the solids, which is also corrosive, can damage the gloves.


Creams and ointments (including steroid creams)

Can not yet tested according to the standards. All creams and ointments containing oils, making the latex and vinyl gloves are not suitable for working with these products. It is recommended to use nitrile or neoprene. A review of the theoretically calculated breakthrough times at selected steroid creams for nitrile Touch N 'Tuff gives times of 120-240 minutes.

By topical application of steroid creams recommended to immediately discard the gloves if it determines that needs something through the gauntlet and after use.
