Safety Standards

At evanssafety we are dedicated to providing up to date information in the 'Safety' industry. To find out more click on the following options.

Hearing Protection

Levels of Protection
Physical Agents (Noise) Directive – 2003/10/EC

This directive is now in place and has taken two years to implement, and became law in early 2006. It requires that any persons working in noise levels between 80dBA (lower action level) & 85dBA must be provided with suitable hearing protection on request.

Where noise levels are at or above 85dBA then suitable hearing protection must be worn.

In addition the new “exposure limit value” requires that no worker may be exposed to more than “87 dBA 8 hour equivalent” under any circumstances, taking into account any hearing protection worn, (the 87dBA level is that INSIDE the hearing protector). There are also new “Action Values” for IMPACT NOISE and the requirement for risk assessments in the workplace is reinforced by article 4 of the new directive.

evans safety can organize complete noise assessments of your workplace and suggest the type of hearing protector that would most suit your workforce.

SNR (STANDARD NOISE REDUCTION)

SNR is only a general means of comparing different ear protectors. Generally higher the SNR number, the better the performance of the ear protector across a range of noise frequencies.

HML Method

The HML method gives a comparable accuracy to the octave waveband system. The HML methods refer to the specific hearing protector at High, medium and low frequencies.

Ear plugs EN352 part 2
Helmet Mounted ear muffs EN352 part 3
Active noise reduction ear muffs EN352 part 5

Introduction to Safety Footwear

Evans safety offers a truly fantastic range of safety footwear, we cover everything from the basic chukka to designer brands, all meet the newest standard EN 20345

To choose the right footwear you need to recognize the risks involved in the day to day activities

  1. Impact resistant toe caps
  2. Pierce resistant midsoles
  3. Anti static soles
  4. Sole resistant to heat
  5. Sole resistant to cold
  6. Water resistant
  7. Resistance to fuel oil
  8. Resistance to chemicals
  9. Slip resistant sole

Checkout the “U” Power range its one of the most advanced technological footwear ranges in Europe. For “U” power the future is now! Just look at the technology this footwear has got to offer, plus most of the technology is patented

  1. Airtoe – Actual breathable toecaps, available in composite 50gr, Aluminium 54gr and Titanium 52gr, a normal steel toecap weighs 95gr
  2. Stress out system – an innovative tongue system to help the instep and allow comfort when walking. This exclusive technology comes from extended studies on the ergonomics of the feet
  3. Save & Flex – the exclusive pierce resistant “No Metal” midsole in comparison to the classic steel midsole is far lighter, more flexible and safer since it is stitched directly into the upper therefore protecting the entire sole area, steel protects roughly 85% of the sole
  4. Insoles – five types of insoles available, Naural Confort 11, ergo Dry, Dual action gel, Relax gel and leather gel – ask for more information!
  5. Wingtex – a revolutionary air tunnel lining for the utmost breathability, special microcells have fantastic absorbance and deabsorbance features

ESD Footwear

There are three standard levels of conductivity:

  1. Antistatic 1 – 1000 Mega Ohms
  2. ESD 0 – 35 Mega Ohms
  3. Conductive 0 – 0.1 Mega Ohms
  • The antistatic standard offers dissipation levels approved by the petro chemical industries as defence against flash point problems. This standard has a 1 Mega Ohm bottom end resistance to guard against mains voltage.
  • The ESD (Electrostatic dissipation) standard EN61340-5-1 and EN100015
  •  The conductive standard offers no protection from mains voltage at all and can therefore prove dangerous if used in general industry. This standard is only used in munitions manufacturing and the MOD

 

Respiratory Introduction

Legislation states employees are responsible for providing suitable respiratory protection to employees who require it, training will be needed in its use, plus maintenance of the product is required and records of maintenance kept. Check out Evans safety services for unrivalled expertise!

The main hazards found in most workplaces are as follows

  1. Dusts – When solid materials are broken down, fine particles are produced into airborne particles
  2. Mists – Tiny liquid droplets formed by atomization and condensation processes like spraying
  3. Meal fumes – occur when metals are vaporized under high heat
  4. Gases – often odourless and invisible , can travel freely and quickly
  5. Vapours – gases formed when solids or liquids evaporate at room temperature

Choosing the right RPE

  1. Identify the hazard – dust, metal fume, gas or vapour
  2. Assess the hazard and the concentration of the contaminant. Never underestimate!
  3. Measure what the likely exposure levels are
  4. Select the correct form of RPE – half mask, full facemask, disposable, powered air or airline
  5. Training – all respiratory users should be trained in the correct fitting, usage and maintanance

European Standards for Respiratory equipment

Respirators are tested to the relevant EN standard and CE marked. All respirators carry the CE mark plus the European standard and performance category markings.

European Standards for Gloves

CE means the gloves comply to a basic requirement laid down by the EEC directive for Personal Protective equipment.

Simple Design (Category 1)

For areas of minimal risk where the effects of not wearing a glove are easily reversible or superficial – such products are self certified.

Intermediate Design (Category 2)

For areas of specific risk ie: mechanical risks, such products will have been EC Type tested against European test methods and certified by a notified body.

Complex Design (Category 3)

For areas/applications that can seriously or irreversibly harm their health. Such products, in addition to CE type test, will also have to be either produced under an approved quality system Or be type tested on an annual basis.

Hi-Visibility

Being struck by a moving vehicle is the second most common cause of death in the workplace today and accounted for 17% of all fatal injuries in 2002/3

In order to comply with all UK and European legislation, you need to ensure that the high visibility garments comply with EN471:2003 table 1, class 2 or 3 which must be worn at all times.

There are 3 classes of high visibility garments based on the levels of visibility they provide, in all cases the bands of reflective material shall not be less than 50mm wide, and the standard specifies minimum areas of banding and background material which is generally fluorescent in colour.

Class Description
Class 1 Lowest protection level – mostly Hi Viz trousers
Class 2 Mid level visibility typically a vest with 1 or 2 bands and braces
Class 3 Highest level of visibility and constructed as a jacket with sleeves and a range of reflective material as 2 bands on the sleeve, and 1 band with braces, 2 bands with braces or 2 bands only. Class 3 garments must be worn on dual carriageways with a speed limit of 50mph and above.
