IMPORTANT INFORMATION ON PPE SAFETY CATEGORIES AND EN STANDARDS....
Posted By Stephanie Hancox on 2017-08-08 09:35
When searching for your PPE needs do you understand the difference between what each EN standard (EN....) refers to? If not then your not the only one, It is common for people to blindly purchase a product based of its description with no regards to the EN Standard which could mean the difference between a successful and an unsuccessful purchase. With our launch of our PPE online shop; We have tried to include variations in EN Standards on the products we offer to ensure the majority of your PPE needs are catered for.
Below we have gathered information around some of the most popular PPE equipment and clearly summarised the importance of each. We hope you find this information useful and helps in your search for the best range off PPE; Have a look at our online PPE shop.
PPE Equipment we have explained the EN Standards of include
Safety Helmets * Eye Protection * Hearing Protection * Respiratory Protection
"Under the Personal Protective Equipment at Work Regulations 1992 (and other related legislation such as COSHH, Noise at Work Regulations, Control of Asbestos Regulations etc) employers have a duty, inter alia, to ensure that any PPE they provide to their employees meets the requirements of the Personal Protective Equipment Regulations 2002."
Guide to choosing your safety helmet...
EN397 - The standard industrial safety helmet standard; This standard goes back over 50 years and testing is only carried out to the top of the helmet. A49J impact only to the crown of the helmet measures the shock absorption and a penetration test with side impact test in this standard only a lateral rigidity test which is a slow progressive force loading and is not an impact test.
EN14052- The standard for high performance industrial safety helmets;The specification includes the requirement for side impact protection. Tests require that the shell is subjected to a total of 150J of impact energy, 100J to the top of the helmet and 50J to the side (up to 60º from the crown) of the helmet.Penetration testing is also required with a blade striker being dropped from 2.5M to give an impact energy of 25J on to the top of the helmet and on to the side of the helmet with an impact energy of 20J from 2M.
EN50365 The standard for electrical insulation;An additional specification for helmets used for working live installations up to 1000V. Testing is carried out at voltages of 10,000V. Vented helmets meet this specification, although they cannot meet the electrical insulation requirements of EN397 and EN14052.
EN14052 the standard for mountaineers; A helmet complying to the mountaineering standard is impact tested with 2 5KG strikers. A hemispherical striker is dropped from 2M onto the crown of he helmet and a flat striker from 500M on to the front, rear or side by tilting the head form to 30º. In all cases, the transmitted force through the neck of the head form must not exceed 10KN. Two penetration tests with a 3KG pointed striker are also performed within 50mm radius of the helmet's crown without making contact with the head form.
EN812 the standard for industrial bump caps;The specification requires the cap being hit 4 times by a 5KG flat steel striker falling with 12J of energy. A bump cap is intended to provide protection against bumps and scrapes to he head, it should not be used where falling or thrown objects are likely and should not be used where falling or thrown objects are likely and should not be used where an industrial safety helmet is required.
Guide to choosing your Eye Protection...
EN166:2001; All safety eyewear has a series of numbers and letters on the frame and lens'. These markings will tell you that the product has been subjected to certain tests within EN166 and found to be suitable for the purpose. As an example a pair of safety spectacles carrying the marking EN166.1.F tells you refractive tolerance +0.06dio, low impact, field of use basic and no resistance to misting or surface damage.
EN170:2002; UV Rays Protection-European Standard for ultraviolet Filters. Requirements relating to the transmittance of filters for protection against ultraviolet radiation.
EN172:2002; Specification for sun glare filters used in personal eye protection for industrial use. Requirements relating to the transmittance of filters for protection against solar radiation.
Guide to choosing your Ear Protection...
The performance of the hearing protector (it's attenuation level) must be adapted to the risk assessment of the workplace. It should bring the noise level to a level that is not harmful to health, while avoiding over protection which would cut the operator off from his environment (warnings, communication, ect).
Exposure to noise is much more than a nuisance. It can be permanently damaging. In work conditions where the noise levels exceed 80db individuals must be provided with hearing protection if they request it. At 85db individuals must be informed and training provided in the use of hearing protection.
How to protect yourself? Firstly, identify the nature of the noise: stable, fluctuating, intermittent or pulse. Secondly, measure the noise at the working station: intensity (dB) and volume (Hz). Thirdly, determine the exposure time and lastly calculate the required reduction to return to a background level acceptable (see directive 2003/10/EC).
|8 hours exposure time at or above 85 db||8 hours exposure time at or above 80db||8 hours exposure time between 75db and 80db|
|Obligatory hearing protection||Hearing protectors available to the worker||Hearing protection recommended|
Guide To Noise Source Hazards
Harmful Area Risk Area Safe Area
Jet Engine 140 dBA Plate Fabrication, Chainsaw 100dBA Busy Traffic 80dBA
Rivetting Hammer 130 dBA Power Tools, Lawnmower 90 dBA Vaccum Cleaner 70dBA
Propeller Aircraft 120 dBA Normal Conversation 60dBA
Rock Drill 110 dBA
EN 352-1 : Hearing Protectors - Ear Muffs
EN 352-2 : Hearing Protectors - Ear Plugs
EN 352-3: Hearng Protectors - Helmet Mount Ear Muffs
Simplified Noise Level Reduction is a way of comparing different hearing protectors performance. The SNRis deducted from the overall sound level to calculate the sound level at the ear when wearing the hearing protector.
Guide to choosing Your Respiratory Protection...
EN 149:2001 + A1:2009; European standard tests to check the conformity with resistance to impacts, to cleansers and disinfectants, to temperature. A1:2009 amendment,filtering dust masks are now classified as either single use/single shift (NR) or reusable/more than 1 shift (R).
TIL; Total Inward Leakage; Leakage of the ambient atmosphere into the respiratory interface.
NRF;Normal Protection Factor- Nominal Level of Protection which can realistically be expected in the workplace conditions.
Dolomite Test (D); Optional Test under EN149 for clogging with dolomite dust. Respirators which pass the dolomite clogging test are proven to provide a more comfortable breathing level and longer lasting performances of filtration.
How to Protect Yourself? Guideline...
|Protects from non-toxic dust and/or water-based aerosols.||Protects from slightly toxic or irritating solid aerosols and/or liquids.||Protects from solid aerosols and/or liquids listed as toxic.|
Examples of Application
