Work gloves expert information, Number 5: Indicator System

 
Providing workers and managers with a quick, simple and effective visual guide to ensure they have the right level of cut protection for the hazards encountered in the workplace is the focus of a new initiative launched by hand and arm protection (HAP) specialists Marigold® Industrial.
 
The company has launched a 3 colour coded large indicator ‘dot’ on the back of its highly acclaimed Puretough™ P Series with each colour signifying a level of cut protection - Green (Cut level 1-2), Amber (Cut level 3-4), Red (Cut level 5).
 
The new Indicator System enables the user to know instantly what level of cut protection is being provided by the gloves and ensure that it is the right level to protect against the hazards being encountered. The Indicator System uses a 3 colour coded system that relates to the level of protection provided by the glove.
 
Colour code 1 – Green (Caution)
Gloves with a large green ‘dot’ on the back of the hand have lower protection (cut levels 1 - 2) and should therefore be used in work areas of minimal cut hazard, e.g. general handling.
 
Colour Code 2 – Amber (Warning)
Gloves with a large amber ‘dot’ have mid-level protection (cut levels 3 - 4) and should therefore be used in work areas where a medium cut hazard is present, e.g. sharp component handling.
 
Colour Code 3 – Red (Danger)
Gloves with a red ‘dot’ have the highest level of protection (cut level 5) and should therefore be used in work areas where a high risk of cut injury is present, e.g. glass & sheet metal handling.

Work gloves expert information, Number 4: Oeko-Tex

 Oeko-Tex 

 Products showing this label respect non-toxicity to humans for direct contact with the skin. It guarantees that:
• Textiles are azoic colorant (carcinogenic) free
• Textiles tested against pesticides and phenol chlorine
• Textiles contain no heavy metals
• Textile with little or no formaldehyde
• Textiles with skin neutral pH
• Textiles are Accelerator free
• Textiles contain no added biocide

When the Oeko-Tex Standard 100 logo appears on our packaging it verifies the protective glove is free from harmful materials, we have recently achieved it for the new Nitrotough™ N1200/N1300/N1500/N1700 range.

Work gloves expert information, Number 3:  Rubber glove chlorination explained...
 
Chlorination is a process which takes place during the manufacture of certain gloves. It involves washing in water containing dissolved chlorine, followed by neutralisation through rinsing to eliminate any residue. The chlorine modifies the chemical structure of the glove´s surface. Chlorination is permanent and irreversible. Chlorination is also sometimes referred to as halogenation.
Our manufacturing plant in Malaysia (MIM) is fully equipped with a water treatment system to filter and clean the water used in the process of chlorination (ISO 14001).
 
ADVANTAGES OF CHLORINATION:
1.      Chlorination makes the glove’s surface slippery thus making it easier to put on (don). Indeed, rubber does not slip particularly natural rubber latex. It is therefore an essential process for rubber gloves without flocking or where there is no powder to help easy donning.
2.      The rubber glove is “cleaner” (no powder, no fibres), thus it can be worn in specific environments such as the food industry.
3.      Chlorination also eliminates the extractible and soluble substances such as proteins or other residuals like accelerators; which considerably reduce the risk of skin allergies.
4.      The chlorination adjusts the pH to neutral providing excellent skin tolerance as our skin is pH neutral too.
 
To summarise, chlorination is a manufacturing process which improves the easy donning and the overall level of comfort of the rubber glove. Chlorination also cleans the glove removing residual proteins and accelerators. The chlorination process results in soft and smooth rubber gloves ensuring consistent wet and dry grip.

Work gloves expert information, Number 2: Traceability system for high cut resistant gloves

In order to offer our customers an additional quality service, we have developed a unique system of traceability on our highest levels of cut resistant gloves (level 5). This new system is  in most of the critical points similar to the quality system used for CE3 gloves (irreversible effects or mortal danger).

 
This system allows the identification of key parameters in order to trace and to identify at all the stages of the manufacturing process, the source and the yarn batch number used for cut resistant glove production:
* delivery date of the yarn batch
* technical specifications attached to this specific yarn lot
* date of first and last production made with this lot of yarn
* internal lab test results on gloves knitted with the yarn lot identified previously

In practice, this traceability system appears at the bottom of each textile tag sawn on the cut resistant glove (see the image).

Below the CE information including pictograms and scores, you’ll find a line ‘Batch no.’ followed by a series of both letters and numbers. All the reports related to the batch number written in the textile tag are preciously kept in MIP plant records.

Work gloves expert information, Number 1: Coatings for chemical gloves
 
Within its wide range of products, CMIG offers 5 different coating materials for chemical gloves to protect the user against chemical risks. The following is a summary about their possible applications:
 
Polyvinylchloride (PVC): This thermoplastic offers high protection against alkalis, salt solutions and a lot of concentrated acids. Many PVC gloves of our range are suitable for HF (hydrofluoric acid). Because of their cost-effectiveness and their robustness high quality PVC gloves are still very popular in the chemical industry, predominately for splash protection. 
production of PVC:

monomer
vinylchloride
activated monomer
polymer, PVC


Natural rubber (NR): This cost-effective "natural product" offers protection against water based chemical solutions like (non-concentrated) acids, alkalis and salt solutions. Furthermore, concerning splash protection NR can be used in a wide range of applications for different chemicals.
 
Nitrile butadiene rubber (“nitrile”, NBR): This elastomer is best used with oil based chemicals such as solvents, oils and greases, except for many halogenated or aromatic hydrocarbons (in many cases only splash protection). Furthermore, nitrile gloves are suitable for alkaline solutions and not high concentrated acids.
 
Butyl rubber (IIR): This synthetic elastomer is nearly impermeable to gas (used as NBC gloves for military). Gloves made of "butyl" are suited for operations with high concentrated acids (hydrofluoric acid) and alkalis as well as alcohols, saturated salt solutions, glycol ethers, glycerol, hydrogen peroxide and so on. Furthermore, the resistance of "butyl" against solvents like aldehydes, ketones (acetone) and esters is excellent.
 
Viton® or fluor carbon elastomer (FKM): This fluoropolymer elastomer or synthetic rubber shows best protection against the following chemicals: aliphatic (like Pentane), aromatic (like toluene) and halogenated hydrocarbons (like chloroform). Furthermore Viton® offers protection against toxic agents like aniline, PCBs (polychlorinated biphenyls), polychlorinated triphenylene and so on.
 
For more information please have a look at the products in our website. If you need help concerning chemical protection our expert team is happy to help with your query.
