Whether buying for yourself, or as a corporate buyer, there is always a decision to be made when buying workwear. Do you choose price as your determining factor or quality? These decisions are particularly appropriate in the financial situation that we all face at this time.
In fact you really need to research the market, you can find reasonably priced garments that are of appropriate quality, and you can also too often find expensive fashion orientated garments that whilst looking good in fact do not have a durable life in actual use.

In fact you really need to research the market, you can find reasonably priced garments that are of appropriate quality, and you can also too often find expensive fashion orientated garments that whilst looking good in fact do not have a durable life in actual use.
Make sure that you know exactly what it is you are looking for and how you want it to perform.
If you need a garment to last a long time with many washes, then normally a slightly higher priced item will have a longer service life, mainly because the material quality, which in fact makes up over 70% of the cost of a garment, will be better able to withstand wear and tear and high temperature washing. Check the detail on the care instructions is always a good tip.
It is important that you know exactly what it is you need. In some cases the articles must comply with regulatory standards as is the case particularly in High Vis and other PPE items. Even then you have to be sure that the claims made by the supplier or manufacturer are fact; the items should be marked clearly as to their compliance to the Standards and the supplier should be willing to supply any data ./ certification required to show that is the case.
At Granite Workwear, we take great pride that we offer a good value workwear product at a sensible price, have passed extensive wearer trials and statutory tests with the proof of this available, are totally fit for purpose and most importantly offer good value for money.
In the 19th Century, John Ruskin made a statement that is as true today as it was 150 years ago. Think of this when you look at our workwear, safety and PPE products.
‘There is hardly anything in the world that someone cannot make a little worse and sell a little cheaper, and the people who consider price alone are that person’s lawful prey. It is unwise to pay too much, but it is also unwise to pay too little. When you pay too much, you lose a little money, that is all. When you pay too little, you sometimes lose everything because the thing you bought is incapable of doing the thing you bought it to do.The common law of business balance prohibits paying a little and getting a lot. It can’t, be done.If you deal with the lowest bidder it is well to add something for the risk you run.And if you can do that you would have enough to pay for something better.’

Employers responsibility for High Vis Clothing.
The following advice is provided by the Health and Safety Executive to Employers regarding their responsibilities in regard to the supply and use of High Vis clothing:-
Storage Facilities must be provided for the clothing when not in use.
Adequate information must be provided along with training and instruction to ensure that employees use High Vis clothing correctly – This should include the explanation of why it is needed, what the risks are and how and when it should be worn.
Employees should be supervised to ensure that the clothing is actually worn and used correctly – whenever it is needed.
The employer must ensure that the High Vis clothing is maintained in a clean state and be in working order. Dirty, oily or greasy high vis garments may give the wearer a false impression of how well they can be seen and in itself could lead to accidents.
If an employee may be exposed to significant risks to their safety whilst at work then it is the employers responsibility to provide clothing free of charge to that employee. Some businesses provide funding to the employee to purchase their own High Vis garments. You must ensure, however, that the correct garments are purchased that comply with the relevant EN or GO/RT3279 standard. If you are unsure that they comply then request to view the garment test report from the supplier. Testing is expensive and suppliers / manufacturers are usually only too pleased to prove that they have jumped through all of the hoops to provice a correctly certified garment. There are garments on the market that do not comply – be aware.

Maintenance of chainsaw clothing
The wearing of chainsaw protective clothing is a legal requirement in many instances.
A report published in the Journal of Forest Engineering in New Zealand concluded that "chainsaw garments which were exposed to even the smallest amount of oil, comprehensively failed cut tests".
Chainsaw clothing must be washed regularly to maintain their protective properties.
Check the label first to see if they can be machine washed and follow the HLCC (wash instructions) to the letter. Remove as much oil and dirt as possible from the surface your trousers or jacket with a light washing detergent. The hotter the wash the better the result you will get but check the label, some garments can only be washed at 40 degrees and some can be washed at 60. After washing, can you spin dry? Check the label, this may affect the blocking material.
Heat has a detrimental effect to the blocking fibres ability to stop a saw chain. If you have burned your trousers, throw them away, they will not give you adequate protection.
Exhaust gasses from chainsaws occasionally burn, scorch or melt the outer fabric and this can have a significant effect on the blocking fibres beneath. Do not take unnecessary risks they will not give you the protection you require.
Should you tear the outer fabric on your garment you are allowed to repair it but you must ensure that you do not interfere with the protective blocking material. Do not sew a patch onto the garment with the thread holding the blocking fibres. Patches should be hand stitched to the outer fabric only. If you stitch in the blocking material you can significantly affect its ability to stop the saw.
The CE standard states that:-
"No personal protective equipment can ensure 100% protection against cutting from a hand-held chain saw".
In the majority of accidents, well-maintained garments will stop the saw. If there is a cut through the garment there will be a significant reduction in the injury. Occasionally when a kick back occurs, the garment stops the rotation of the saw, but the impact forces the teeth through the blocking material giving puncture wounds. No garment can protect from this.
It would be wise to keep a couple of packets of Celox material – one in the trouser and one in the truck to ensure that any deep cuts can be treated effectively.

Safety Gloves for Mechanical and other Hazards
In a previous article we gave details of Safety Gloves for protecting against the risk of handling chemical and biological hazards, now we will give information on other types of safety gloves to protect against other hazards.
Safety Gloves should be issued and worn after undertaking a Risk Assessment for people who have to handle or come into contact with:
The types of materials most commonly in use are:
There is also a pictogram for gloves that have a particular resistance to impact cuts
At no time should protective gloves be used as an alternative to the fitting and proper use of guards on machinery or tools.
Thermal Hazards
Gloves that are resistant to thermal hazards either heat or cold can be manufactured using a variety of materials.
a. Resistance to convective cold 0 to 4
b. Resistance to contact cold 0 to 4
c. Permeability to water 0 to 1
The Pictogram used to show that gloves are resistant to cold is
In the standards for resistance to heat the following categories are used:
a. Resistance to flammability 0 to 4
b. Resistance to contact heat 0 to 4
c. Resistance to convection heat 0 to 3
d. Resistance to radiant heat 0 to 4
e. Resistance to small pieces of molten metal 0 to 4
f. Resistance to large splashes of molten metal
The pictogram used to show the gloves resistance to heat is
There also standards applicable particularly to chainsaw protective gloves that have been covered in previous articles on the Granite Workwear web site see A Guide to Chainsaw Protective Clothing and Equipment published 11th June 2010.
In our range of gloves we have products that cover all aspects of protection.
Safety Gloves should be issued and worn after undertaking a Risk Assessment for people who have to handle or come into contact with:
- Materials with sharp or rough edges
- Very hot or very cold materials
- Fire
- Electrical current
- EN 388 is for gloves designed to provide protection against mechanical risks. It specifies requirements for resistance to damage from abrasion, perforation, tearing and cutting.
- EN 407 is for gloves designed to provide protection against thermal hazards e.g. heat and or fire.
- EN 511 is for gloves designed to protect from cold conditions.
- EN 12477 is for gloves designed to give protection when using welding equipment.
The types of materials most commonly in use are:
- Latex natural rubber is a very elastic and flexible material depending on the formulation of a particular glove, natural rubber can offer abrasion, tear and cut resistance. However some people suffer allergic reactions to latex, so individual user requirements must be taken into account.
- Nitrile gives excellent abrasion and puncture resistance whilst retaining flexibility and comfort. It is also less likely to cause allergic reactions.
- Polyvinyl Chloride PVC can offer abrasion and puncture resistance, if thick enough it can afford some cut protection. Generally tear resistance is poor.
- Leather a natural material can be modified during the tanning process to give different properties. Leather gloves come in a large range of thickness and styles and vary widely in protection given, from specialised to very basic general purpose gloves.
- Kevlar™ brand fibre (Par Aramid fibre) a specialist artificial yarn from which gloves and sleeves can be knitted. These have excellent tear, abrasion and cut resistance.
There is also a pictogram for gloves that have a particular resistance to impact cuts
Thermal Hazards
Gloves that are resistant to thermal hazards either heat or cold can be manufactured using a variety of materials.
- Aluminised gloves help with the reflection of heat and are normally used where the main source of heat is radiant e.g. in a blast furnace. Materials often aluminised are Para Amid and leather.
- Leather is a good protective material against cold as long as it does not get wet and often they are treated with waterproofing agents. Leather is also a good material for welding gloves as it does not melt or burn unlike many synthetic fibres.
- Poly Viloft is a synthetic fibre that gives good thermal insulation properties against cold.
- Para Aramid e.g. Kevlar™ developed for aerospace to give heat resistance for the extreme temperatures during re-entry into the Earth’s atmosphere, is extremely good against flame, and convection heat.
- Cotton has only moderate resistance to heat and cold, the main problem is that to be effective the material has to be thick which limits dexterity.

b. Resistance to contact cold 0 to 4
c. Permeability to water 0 to 1

Safety Gloves for Chemical and Biological Hazards
Safety Gloves should be issued and worn after undertaking a Risk Assessment for people who have to handle:
The use of protective gloves should be seen as a control measure of last resort and should always be used in conjunction with other measures. This is because:
There are various standards that have to be achieved for different risks.
EN 374 is for gloves designed to protect from chemicals and micro-organisms. This standard specifies the requirements of gloves for protection against chemicals and/or micro-organisms. Specific Requirements are that gloves need to be:
There are four factors to consider when deciding which glove is suitable for your work
(a) The type of hazard (chemical type, Bio-hazard)
(b) The task
(c) The user (size and fit, state of health, etc.)
(d) The workplace conditions (ergonomics, temperature, wet or dry, etc.),
They need to be considered together and not in isolation as it is the interaction of all these points that will determine the suitability of the glove.
In the Risk Assessment it is not enough to simply state that gloves are required, the type of glove must be specified along with any other control methods used to avoid or limit contact and also any special measures that must be taken to ensure that the protection of the glove is maintained, for example specifying when gloves should be changed.
Chemical Hazard
It is impossible for one glove material to offer complete protection from all substances/chemicals. All of them are liable to damage or failure by degradation or permeation by some chemicals. In most instances where there is need for protection against accidental contact, a nitrile glove will be the best choice.
Degradation is damage caused by changes in one or more of the physical properties after contact with the chemical, signs of degradation are normally visible with indications being swelling, loss of flexibility or areas of stickiness.
Permeation is where a chemical passes through the glove material by diffusion without damaging the actual glove, this is normally expressed as the ‘breakthrough time’, this is the measure of how quickly a chemical can permeate the glove and will be specific for the particular model of the glove.
Generally the thicker the glove, the longer the breakthrough time is. The breakthrough time is the maximum time that it can be used in contact with the hazard and must be changed at that time even if the task has not been completed. Breakthrough time can also be impacted adversely if the chemicals are warmer then the ambient temperature and also are of higher concentration.
If the task involves working with chemicals classed as toxic, harmful on skin contact or capable of absorption through the skin you should always consult the material safety data sheets for the chemicals used, or a chemical resistance chart to select the most suitable type of glove.
Whereas the thicker the material generally the more resistance the need for dexterity has to be taken into account in the selection of the glove. Also the cuff length must be taken into account; generally disposable gloves cover only a small area of the wrist, often leaving a gap between the glove and the sleeve of the protective clothing. There are longer gloves available to eliminate this.
Grip requirements also need to be taken into account, if working in wet and oily conditions gloves with a textured surface should be used.
Abrasion, puncture, tearing and snagging risks also have to be taken into account, generally disposable gloves do not offer good resistance to these hazards and therefore thicker re-usable gloves should be considered.
User requirements
Using the correct size of gloves is essential; gloves that are too small will restrict the hand and cause fatigue and rashes. Gloves that are too large are also uncomfortable, interfere with grip and can easily get snagged, a full range of sizes should be available.
Many people are allergic to latex and exposure can cause rashes, breathing problems and in very rare cases anaphylactic shock. In this case then nitrile gloves should be used.
Any cuts and abrasions on the hands should be covered with a waterproof dressing before donning the gloves.
If somebody has eczema they may need to use a cotton liner inside the gloves. Also they should use a moisturising cream after washing their hands after using the gloves.
Granite Workwear have a comprehensive range of safety gloves suitable for all uses on our website.
In a later article we will be looking at Safety Gloves for Mechanical and Other hazards.
- Hazardous materials
- Toxic chemicals
- Corrosive materials
The use of protective gloves should be seen as a control measure of last resort and should always be used in conjunction with other measures. This is because:
- Gloves only protect the wearer – they do not remove the contaminant from the workplace environment.
- If protective gloves are used incorrectly, or badly maintained, the wearer may not be protected - when gloves fail they fail completely which then exposes the user to the hazard.
- Gloves themselves can cause skin problems.
- Wearing gloves interferes with the wearer’s sense of touch.
- The extent of protection depends on good fit.
- Some types of glove are inconvenient and interfere with the way people work.
There are various standards that have to be achieved for different risks.
EN 374 is for gloves designed to protect from chemicals and micro-organisms. This standard specifies the requirements of gloves for protection against chemicals and/or micro-organisms. Specific Requirements are that gloves need to be:
- Sealed against penetration of liquids according to method in EN 374-2. This test is a pass/fail test.
- Permeation resistance to chemicals tested according to method EN 374-3. Each combination of glove/chemical is classified according to the time the glove resists to permeation of the chemical.
There are four factors to consider when deciding which glove is suitable for your work
(a) The type of hazard (chemical type, Bio-hazard)
(b) The task
(c) The user (size and fit, state of health, etc.)
(d) The workplace conditions (ergonomics, temperature, wet or dry, etc.),

Examples of Chemical Hazards
| Area | Example of Hazard |
|---|---|
| Engineering | Metalworking fluids, oils, solvents, degreasers, adhesives, cement, etc. |
| Laboratory | Acids, alkalis, oils, solvents, etc. |
| Maintenance | Solvents, oils, paint, epoxy resins, degreasers, cements, tar, etc. |
| Printing | Processing chemicals, inks, plate cleaning solvents, adhesives, etc. |
| Catering | Dishwasher liquids, oven cleaners, surface cleaning agents, water, etc. |
| Agriculture | Pesticides, weed-killers, oils, solvents, etc. |
| Cleaning | Bleaches, cleaning agents, detergents, water, etc. |

A Guide to Chainsaw Protective Clothing and Equipment
Chainsaws are potentially one of the most dangerous tools in general use, the saw is made to cut easily through large branches and tree trunks so any part of the human body will have no resistance at all to the cutting power in use.
Therefore there are recognised standards for the PPE required to minimise the risks in the case of clothing these are the standards EN 381. These standards specify levels of protection related to the speed of the chain and also the amount of coverage of the protected areas.
Class 0 resists chains up to the speed of 16 metres per second
Class 1 resists chains up to the speed of 20 metres per second
Class 2 resists chains up to the speed of 24 metres per second
Class 3 resists chains up to the speed of 28 metres per second
Class 4 resists chains up to the speed of 34 metres per second
There are also different parts to the standards each of which covers a specific part of the body:
EN 381-5 Leg protection
This is split into 3 different levels A, B and C and the minimum requirement is Class 1
A protects the front and ride side rear to both legs
B gives additional protection to rear left side of the right leg
C gives all round protection to both legs
EN 381-7 Chainsaw Gloves
This is split into 2 Different Levels A and B
A gives protection to the left hand
B gives protection to both hands
EN 381-9 Chainsaw protective Gaiters
These are recommended for occasional chainsaw users when working on even ground with little risk of tripping or snagging, worn in combination with steel toecap safety boots
EN381-11 Upper part of Body
These garments are normally Class 0 as to achieve higher levels would involve so many layers of material that the garment will be too heavy and unwieldy, leading to lack of mobility and the increased risk of heat exhaustion, both of these will have a negative impact on Safety.
There is a separate standard for Footwear EN 17249:2004
These items cannot be Class 0, they can be Class 1, Class 2 or Class 3 and are the only items that can achieve Class 4 status.
They must be marked with the Year and Quarter of manufacture.
How does chainsaw protection work?
There is no flexible material that can be worn as clothing, gloves or boots that can be totally impervious to cuts from chainsaw blades. Therefore a number of layers of protection are the only way forward.
The outer layer normally comprises of a material that is tough and slippery, this is mainly to ensure that outer surface is resistant to minor damage from thorns and other snagging mediums, which could expose the under protective layers. Beneath this, long, loose fibres of ballistic nylon or Kevlar are layered. When a saw contacts the trousers, the outer layer is immediately cut and the nylon or Kevlar is drawn out and wraps around the saw's drive sprocket, locking it solid and halting the chain, thereby limiting damage to the operator's limb.
Once the item has been cut it must be scrapped as the protection has been totally compromised. The saw must be stripped down and the fibres fully removed before using it again.
Marking
All Chainsaw protective clothing, boots and gloves sold in the EU must carry a pictogram depicting a chainsaw and information of the Class and Design it is rated to, this pictogram must be a minimum of 30mm x 30mm. For example:
Other items that must be used when using a chainsaw are:
Safety Helmet to the minimum standard EN 397 but recommended to EN 12492 if involved in tree climbing operations.
Hearing Protection to EN 352-1 (noise levels are typically 115 dB)
Eye Protection Mesh Visor to EN 1731
Safety Glasses to EN 166
As these are used for protection in other activities not just for chainsaw work they do not have to be marked with the pictogram.
Granite Workwear has always kept up to date with the latest developments in Chainsaw Protective Clothing and Equipment and indeed have a specialist Forestry section on the web site which is subdivided into Clothing, Footwear and Tools and Accessories. New items are added on a regular basis as they become available, we are very happy to answer any questions you may have on what is the best solution for your particular needs.

New items are added on a regular basis as they become available, we are very happy to answer any questions you may have on what is the best solution for your particular needs.
