Understanding noise exposure terms

Noise exposure terminology – Take a look at our explanatory video below and check below that for our glossary:

Exposure action values (EAV): Levels of noise exposure to noise at which certain actions need to be taken. The values are:

  • Lower exposure action values (LEAV):
  • daily or weekly exposure of 80 dB:
  • peak sound pressure of 135 dB;
  • Upper exposure action values (UEAV):
  • daily or weekly exposure of 85 dB;
  • peak sound pressure of 137 dB.
Exposure action values and noise exposure limit values
Daily or weekly personal average noise exposurePeak sound levelActions
Below lower exposure action valuesLess than 80 dB
(A-weighted)
Less than 135 dB
(C-weighted)
Reduce noise levels as far as reasonably practicable.
Lower exposure action values80 dB

(C-weighted)
or aboveCannot take the effect of hearing protection into account
Undertake risk assessment. If any employees are identified as being particularly susceptible to noise, health surveillance should be implemented.

Make suitable hearing protection available.

Establish a maintenance programme for equipment supplied to reduce noise risk such as noise limiters and hearing protection.

Provide training.

Upper exposure action values85 dB
(A-weighted)
or aboveCannot take the effect of hearing protection into account
137 dB
(C-weighted)
or aboveCannot take the effect of hearing protection into account
Implement the actions required by lower exposure action values (above).

Establish and implement a programme of control measures.

If these measures are not sufficient to reduce exposure below 85 dB then:

  • suitable hearing protection must be worn; and
  • a health surveillance programme implemented.
Exposure limit values87 dB
(A-weighted)

Allowed to take hearing protection into account
140 dB
(C-weighted)
Allowed to take hearing protection into account
Must reduce to below limit values.

LAeq: The ‘equivalent’ continuous noise level that would deliver the same noise dose as a varying level over a given period, and is a good way of describing the average level of noise.

LEP,d: Daily personal noise exposure level. It is averaged over an 8-hour period rather than the actual time in the work environment.

LEP,w: Weekly personal noise exposure level. It is averaged over a period of 5 days (40 hours) by measuring the noise exposure on each of 7 days, then dividing the result by 5.
Limit values: See ‘Exposure limit values’.

Noise dose: See ‘Noise exposure’.

Noise exposure: ‘The noise dose’, which can be calculated, takes account of the actual volume of sound and how long it continues. Noise exposure is not the same as sound level, which is the level of noise measured at a particular moment.

Noise limiters: Sometimes known as volume regulatory device (VRD), controls noise exposure from amplified music. Modern noise limiters can be fitted with anti-tamper relays connected to external switches to improve system security.

Noise measurements: Decibels (dB) are used for measuring noise. A-weighting is used to approximate to the frequency response of the human ear. C-weighting is used to measure peak, impact or explosive noise.

Occlusion effect: Occurs when an object (like an unvented earplug) completely fills the outer portion of the ear canal. This changes the way sounds are produced in the ear canal, especially noises produced by the body (for example breathing, swallowing and noise travelling through bone and tissue.) The result is these noises appear louder.

Simple listening checks: An easy way of establishing whether there might be a noise problem. Where it is difficult to hold a normal conversation without shouting or where there is live amplified music (as in a pub, club or pop concert) it is probable that the noise is above the lower exposure action value.

Single number rating (SNR) value: Method of indicating the degree of protection offered by a hearing protector.

Sound restoration: Device in earmuffs that reduces ambient noise levels to allow relayed communication or other signals at a reduced level.

Three-decibel rule: The sound intensity doubles with every three dB increase. Thus sounds at 88 dB are actually twice as intense as they are at 85 dB and 115 dB is 1000 times as intense as 85 dB.

Tinnitus: Buzzing, ringing or tone in the ear. Temporary tinnitus is a warning; a sign that ‘you got away with it that time.’

VRD: Volume regulatory device (see noise limiter).

Fire Safety – Assessing the means of escape

Fire risk assessment – assessing the means of escape

The range of workplaces covered by these regulations is huge and so the following information is intended as a guide to get you started on an assessment.  Our advice is to get expert help from one of our experienced safety consultants conducting a fire risk assessment at your premises, please call us on 01453 800100 or contact us for more information on our safety consultancy and fire risk assessment / fire risk audit services.

Please note that in some cases, it may be necessary to provide additional means of escape or to improve the fire protection of existing escape routes. At this point you should consult the fire authority and, where necessary, your local building control officer before carrying out any alterations.  The distances given below should ensure that people are able to escape within the appropriate period of time. You can of course use actual calculated escape times but should do so only after consulting a fire safety consultant with appropriate training and expertise in this field.

Fire risk categories for assessing the means of escape

In general, most workplaces can be categorised as high, normal or low risk. Examples of the type of workplace or areas within workplaces likely to fall within these categories are:

High

  • Where highly flammable or explosive materials are stored or used (other than in small quantities).
  • Where unsatisfactory structural features are present such as:
  • lack of fire-resisting separation;
  • vertical or horizontal openings through which fire, heat and smoke can spread;
  • long and complex escape routes created by extensive subdivision of large floor areas by partitions, or the distribution of display units in shops or machinery in factories; and
  • large areas of flammable or smoke-producing surfaces on either walls or ceilings.
  • Where permanent or temporary work activities are carried out which have the potential for fires to start and spread such as:
  • workshops in which highly flammable materials are used, e.g. paint spraying;
  • areas where the processes involve the use of naked flame, or produce excessive heat;
  • large kitchens in works canteens and restaurants;
  • refuse and waste disposal areas; and
  • areas where foamed plastics or upholstered furniture are stored.

or, where there is a significant risk to life in case of fire, such as where:

  • sleeping accommodation is provided for staff, the public or other visitors in significant numbers;
  • treatment or care is provided where the occupants have to rely upon the actions of limited numbers of staff for their safe evacuation;
  • there is a high proportion of elderly or infirm people, or people with temporary or permanent physical or mental disabilities, who need assistance to escape;
  • groups of people are working in isolated parts of the premises such as basements, roof spaces, cable ducts and service tunnels etc; and
  • large numbers of people are present relative to the size of the premises (e.g. sales at department stores) or in other circumstances where only a low level of assistance may be available in an emergency (e.g. places of entertainment and sports events).

Normal

  • Where any outbreak of fire is likely to remain confined or only spread slowly, allowing people to escape to a place of safety.
  • Where the number of people present is small and the layout of the workplace means they are likely to be able to escape to a place of safety without assistance.
  • Where the workplace has an effective automatic warning system, or an effective automatic fire-extinguishing, -suppression or -containment system, which may reduce the risk classification from high risk.

Low

  • Where there is minimal risk to people’s lives and where the risk of fire occurring is low, or the potential for fire, heat and smoke spreading is negligible.
  • The work you have done on assessing the risks and reducing the risk of fire occurring, together with the knowledge you have gained about the location of people at risk, should generally provide you with the information you need to establish the risk category or categories of your workplace.

General principles for escape routes

Other than in small workplaces, or from some rooms of low or normal fire risk, there should normally be alternative means of escape from all parts of the workplace. Routes which provide means of escape in one direction only (dead-end) should be avoided wherever possible as this could mean that people have to move towards a fire in order to make their escape. Escape routes should be independent of one another and arranged so that people can move away from a fire in order to make their escape and should always lead to a place of safety. Remember that they should also be wide enough for the number of occupants and should not normally reduce in width and be kept clear of obstruction at all times.

Evacuation times and length of escape routes

The aim is, from the time the fire alarm is raised, for everyone to be able to reach a place of relative safety, i.e. a storey exit (see ‘Technical terms relating to means of escape’), within the time available for escape.The time for people to reach a place of relative safety should include the time it takes them to react to a fire warning.

This will depend on a number of factors including:

  • what they are likely to be doing when the alarm is raised, e.g. sleeping, having a meal etc;
  • what they may have had to do before starting to escape, e.g. turn off machinery, help other people etc; and
  • their knowledge of the building and the training they have received about the routine to be followed in the event of fire.
  • Where necessary, you can check these by carrying out a practice drill.

To ensure that the time available for escape is reasonable, the length of the escape route from any occupied part of the workplace to the storey exit should not exceed:

Where more than one route is provided

  • 25 metres – high-fire-risk area;
  • 45 metres – normal-fire-risk area;
  • 60 metres – low-fire-risk area.

Where only a single escape route is provided

  • 12 metres – high-fire-risk area;
  • 18 metres – normal-fire-risk area (except production areas in factories);
  • 25 metres -low-fire-risk area.

Where the route leading to a storey exit starts in a corridor with a dead-end, then continues via a route which has an alternative, the total distance should not exceed that given above for ‘Where more than one route is provided’. However, the distances within the ‘dead-end portion’ should not exceed those given for ‘Where only a single escape route is provided’.

People with disabilities

You may need to make special arrangements for staff with disabilities, which should be developed in consultation with the staff themselves. British Standard 5588: Part 8 gives guidance and provides full information.

Premises providing residential care and/or treatment

The distances shown in the paragraphs above may not be suitable for workplaces providing residential care – you should seek specialist advice from your fire safety consultant in this situation.

Number and width of exits

There should be enough available exits, of adequate width, from every room, storey or building. The adequacy of the escape routes and doors can be assessed on the basis that:

  • a doorway of no less than 750 millimetres in width is suitable for up to 40 people per minute (where doors are likely to be used by wheelchair users the doorway should be at least 800 millimetres wide); and
  • a doorway of no less than 1 metre in width is suitable for up to 80 people per minute.
  • Where more than 80 people per minute are expected to use a door, the minimum doorway width should be increased by 75 millimetres for each additional group of 15 people.

For the purposes of calculating whether the existing exit doorways are suitable for the numbers using them, you should assume that the largest exit door from any part of the workplace may be unavailable for use. This means that the remaining doorways should be capable of providing a satisfactory means of escape for everyone present.

Inner rooms

You should avoid situations where the only escape route for people in an inner room is through one other room (the access room). The exception to this is where the people in the inner room can be quickly made aware of a fire in the outer one and this is not an area of high fire risk. Where there is no automatic fire detection system, it may be reasonable to provide a self-contained smoke alarm which is solely within the access room, as long as it is clearly audible within the inner room.

Corridors

Corridors should generally be a minimum of 1 metre wide (although wheelchair users will need a width of 1.2 metres and a width of 1.5 metres is preferable). The doors should be aligned with the walls of the rooms so that the floor area is effectively divided into two or more parts. To avoid having to travel long distances in corridors affected by smoke, those corridors which are more than 30 metres long (45 metres in offices and factories) should be subdivided into approximately equal parts by providing, close-fitting, self-closing fire doors.

Where a corridor only leads in one direction, or serves sleeping accommodation, it should be constructed of fire-resisting partitions and self-closing fire doors (this does not apply to toilets).

If you would like assistance with any aspect of fire risk assessment please call one of our expert fire safety consultants on 01453 800100.  We can complete a comprehensive fire risk assessment / fire risk audit for your workplace, just contact us to find out more.

Storage of petrol and diesel fuel in the workplace


Important: Please note that we do not provide advice on this issue unless you are a retained client under our Safety~net support scheme. if you’d like to explore the benefits of membership please contact us or request a callback.


Guidance on Storage of petrol

Many businesses store quantities of petrol fuel within the workplace.  They could be for plant and equipment used on site such as lift trucks, or for maintenance needs, strimmers, lawnmowers and the like.  However, you are storing a highly flammable substance and certain precautions are required but what are they?

Since the introduction of DSEAR (Dangerous Substances and Explosive Atmospheres Regulations), there are no longer any specific controls over the storage of petrol at workplace sites other than at petrol filling stations. However, you will need to follow the requirements of DSEAR as petrol is classified as a ‘dangerous substance.’

Key requirements for the safe storage of petrol

If the petrol is being stored in a place which is also a workroom then no more than 50 litres of highly flammable liquids should be stored – this is a general requirement which applies as much to thinners or any other highly flammable liquids as it does to petrol.

If the storage area is not a workroom, then DSEAR also requires, as far as is reasonably practicable, risks from ‘dangerous substances’ are controlled and to mitigate against the effects of any fire or explosion arising from these dangerous substances. This means conducting a risk assessment and recording its findings then acting on them. Identifying how you can reduce risks to a minimum – look at the storage area to ensure that:

  • It does not have any sources of ignition and none should be bought into the area (compressors, electrical switching)
  • It should be properly ventilated (large vents in doors and on one outside wall would be good practice)
  • It should be secure (padlocked and not able to be accessed except by authorised persons – consider arson risks also)
  • Refilling of equipment should preferably take place in the open air and away from sources of ignition (you could refill on hard standing outside and clear of the building – something your insurers will appreciate as well as the environment)
  • Care is taken to avoid spills and the consequences of a leak or spill is assessed(could a spillage leak to surface water drains – the consequences could be serious for the environment and your business)
  • Containers should be kept closed when not in use.

Storing diesel

There are no specific legal requirements on how to store diesel or the quantity allowed either in workplaces or domestic premises. It is not, from a health and safety point of view, a particularly hazardous substance within the meaning of the Dangerous Substances and Explosive Atmospheres Regulations 2002 – its vapour flash point is too high. This means that its vapour will not ignite at normal room temperatures.

That said, there are some general issues you’ll need to take into account:

  • no ‘hotwork’ should be performed on the vessel unless it is emptied and purged of any remaining vapour.
  • the drum should be positioned away from any source of direct heat.
  • the drum should be located in an area where there is no risk of collision with vehicles, fork-lift trucks etc. (diesel splashing onto a hot engine will probably ignite).
  • leaks and spills should be contained to the vicinity of the drum and mopped up quickly, to lessen the risk of slipping.
  • refilling and dispensing activities need to take account of manual handling issues etc.

While diesel is not a particularly dangerous substance from a health and safety point of view, it is an environmental hazard, with considerable clean-up costs if it should leak into a drain, watercourse or the soil. You may, therefore, wish to contact the Environment Agency for further information.

More good advice on safe storage of petrol

Cans and drums can provide an adequate means of storing petrol. When considering this method of storage remember to take into account the method by which the petrol will be used or disposed of and whether the use of small containers increases the overall risks and handling problems during their filling and emptying (think about manual handling). Where you need to store larger quantities than 300litres you should consider installing tanks and referring to the more detailed advice in HS(G)51. You should not store more than 50 litres of petrol within a workroom and then only when it is kept in a properly labelled metal cabinet or bin with adequate spillage retention.

Containers should, where reasonably practicable, be stored in the open air at ground level (singularly or in stacks). This enables leaks to be quickly seen and any vapours to be easily dispersed. They should not be stored on the roof of a building. Where the best option of storing containers outside is not reasonably practicable they should be kept in suitable storerooms, preferably separate buildings, specifically designed for the purpose.

Finally, remember that other activities, including filling and emptying containers, must not be carried out in the designated storage area. This is to prevent other activities that are a higher risk causing a fire, which then spreads to involve the larger quantities in storage.

Notes on application

Information should be incorporated into your Risk Assessments, Health and Safety Policy or Construction Phase Health and Safety Plan (CDM Regulations).  If you have questions please post below, more information can also be found from manufacturers safety data sheet (MSDS).  Don’t confuse this with COSHH Risk Assessment but you can refer to section 16 – Storage Requirements.

HSE Fee For Intervention has been served on an individual worker

HSEWith almost 12 months elapsed since the introduction of Fee For Intervention (FFI) we have heard for the first time of an individual being fined under the scheme.

The individual was employed as a scaffolder working on a Carey Housing project.  The HSE Inspector was driving by the site when he noticed the scaffolder working without edge protection, or any other method that might prevent him from failing.

The Inspector spoke directly to the scaffolder and explaining what he had observed regarding the material breach which the scaffolder had made. The result was that the scaffolder was personally issued with an Enforcement Notice and fined £400.

The Project Manager was next to be interviewed and discussions took place with regard to the role of the Principle Contractor under CDM, training requirements, competency, safe systems ofwork (including review of the sub-contractor’s method statements and risk assessments).

Perhaps not surprisingly the Inspector’s opinion was that the method statement submitted needed to be made more site specific. The detail which was omitted was the method of protection the scaffolder would be using — this should not be “generic” or left entirely to the scaffolder to decide upon but specified in writing.

No action taken against Careys, as the Principal Contractor, on this occasion, as the Inspector was, in general, pleased with what he had seen at site. However, the Inspector warned that individuals are being targeted and will continue to receive fines and an Enforcement Notice from the HSE if they break the law.

Examples of material breaches could include but are not limited to; failing to wear PPE, operating plant and equipment without the relevant training, failing to adhere to the method statement and risk assessments (RAMs), or for altering scaffolds if you are not trained.

The lesson?  Use your RAMS as working documents – this is how our documents have always been produced.  If you need help updating your own please call us for a clear and competitive cost.

Lyme disease and the risk to landscapers and construction workers

In May 2013 a petition was handed to the Department of Health demanding better diagnosis and treatment of Lyme disease.  You may be aware of its existence but many are not but it can present an occupational risk which affects a range of professions and trades with up to 3,000 new cases being reported each year in the UK.  Lyme disease has no vaccination and can be very damaging if left untreated severe fatigue, heart problems, nerve damage and headaches.

  2. Landscapers
  3. Landscape architects
  4. Environmental professionals
  5. Highways specialists
  6. Structural engineers
  7. Ground workers
  8. Arboriculture workers
  9. Forestry workers
  10. Farm workers
  11. plus foragers, hikers, mountain bikers and so on

Lyme disease is spread to humans via ticks with heathland, rough grassland and woodland being the primary sources but you can still catch ticks whilst being in a garden – I removed one from my 4 year old boy just last week!

As we said, a vaccine doesn’t exist but you can reduce your chances of being bitten;

  1. wear long sleeved trousers and shirts – even in warm weather;
  2. If clothes are light in colour ticks can be more easily spotted and removed before they bite;
  3. Give workers information so they can identify ticks, before they’ve fed they can be no bigger than poppy seeds, they don’t fly but they do crawl quickly after jumping onto you from a nearby branch or plant;
  4. Get workers to check themselves after working in known tick zones (even in the harder to reach areas!);
  5. If you are working in a known tick zone then clothes can be treated with permethrin based repellents which can kill ticks on contact.  But, check first with staff and give them a choice allowing them to refer to their GP or pharmacist if required.

Tick removal

To minimize tick exposure, wear rubber boots and tuck pant legs into the boots so ticks have a hard time grabbing on, advise Mississippi State University experts. (Photo courtesy of Jerome Goddard. Used with permission.)

Perhaps the most important element of protecting your self is removing a tick correctly, we’ve summarised this below but you can also see this link for more information and to purchase a specialist tool if your staff are working in high risk areas; http://www.bada-uk.org/defence/removal/indextickremoval.php

  1. Grasp the tick as close to the  skin as possible and pull upwards with steady, even pressure. Do not twist or jerk the tick as this may leave the mouth parts embedded or cause the tick to regurgitate infective fluids.
  2. Remove any embedded mouth parts with tweezers or a sterilised needle.
  3. Do not squeeze or crush the body of the tick, because its fluids (saliva and gut contents) may contain infective organisms.
  4. Do not handle the tick with bare hands, because infective agents may enter through breaks in the skin, or through mucous membranes (if you touch eyes, nostrils or mouth).
  5. After removing the tick, disinfect the bite site and wash hands with soap and water.
  6. Save the tick for identification in case you become ill within several weeks. Write the date of the bite in pencil on a piece of paper and put it with the tick in a sealed plastic bag and store it in a freezer.
    1. DO NOT use petroleum jelly, any liquid solutions, or freeze / burn the tick, as this will stimulate it to regurgitate its stomach contents, increasing the chance of infection.tick-bite-lyme-disease-risk-assessment

Ensure that your staff are aware of the potential risk and know what to do.  Not all ticks will carry the disease but these simple precautions (and a pair of special tweezers) will protect your staff from harm.
