2. General Health and safety advise

Asbestos is a class 1 carcinogenic and must be handled

with care.

Being exposed to asbestos can cause asbestosis,

mesothelioma and lung cancer.

It is imperative that the correct training has been give

prior to any individual working with asbestos.

Approved breathing apparatus must be used at all times

whilst you are working with asbestos.

2.1 Health and Safety Executive.

For health and safety guidance relating to asbestos, please use the HSE

website http://www.hse.gov.uk/asbestos/

3. Calculating Airflow Required for Adequate Air Changes in Enclosure

Prior to removing any asbestos, a secure enclosure must be constructed and

smoke tested to ensure there are no leaks in the structure.

Whilst asbestos removal is taking place, the polythene enclosure has to be

under negative pressure to ensure no contamination can escape into the

external atmosphere.

In order to maintain a constant negative pressure within the enclosure,

sufficient airflow must be maintained to keep the enclosure pressure at -8Pa.

To calculate the enclosure volume, multiply the width x length x height.

If the enclosure is an awkward shape, it may be easier to break it down to

smaller areas and add the total together.

Once you have the volume of the enclosure you must multiply this by the

number of required air changes to give you the airflow required.

Example: Enclosure size Width 9mtr x Length 8mtr x Height 3mtr = 216m3

Volume 216 x (Number of air changes) 8 = 1,728m3/h required.

For reference and information regarding airflow and enclosure calculations,

please follow the link below.

4. Transportation

Negative pressure units are designed to be portable and as light as possible.

The NPU is a machine containing electrical and mechanical moving

components, care must be taken during transportation to ensure no damage

is incurred.

When the NPU is being transported in a vehicle, it is essential that the

machine is secured properly and does not move around the vehicle

uncontrollably potentially causing internal damage to the machine.

When the machine is being loaded and unloaded onto vehicles, it is critical

that the machine is not dropped.

If any damage is incurred during use or handling, Beacon recommends that

you return the machine to your distributor for re-testing.

4.1 Manual Handling

When you are loading NPU’s on and off of vehicles, please ensure you lift

using the correct technique, keep your back straight and bend your legs.

Please the diagram below for recommended lifting values at various heights.

Page 4


4.2 Storage

When storing your negative pressure units, the following instructions must be

adhered to:

a. Always store NPU’s in a dry storage area, wet or damp environments

will have a detrimental effect on the HEPA filter and internal electrical

components.

b. Never leave NPU’s outside in the rain, if ever the equipment does get

wet, you must dry off any water immediately.

c. Always store NPU’s upright on their feet or wheels, storing them on

their sides will potentially cause damage to the HEPA filters and under

certain circumstances could lead to HEPA filters failing or even

bursting.

d. Make sure that all NPU’s placed into storage are sealed and that no

unauthorised persons can accidentally gain access to this equipment

and subsequently contaminate themselves.

5. NPU Operation and Controls

Beacon International have been manufacturing NPU’s for almost 25 years,

the company philosophy has always been to produce high quality easy to

operate equipment consistently.

5.1 On Site safety and pre use checks.

Prior to using any NPU on a work site, always check that the machine has no

obvious signs of external damage, if you are unsure or suspect the machine

may not be fit for purpose, contact your supervisor as soon as possible.

5.2 Attaching Negative Pressure Unit to an Enclosure

NPU’s are designed to create and maintain a negative pressure within an

asbestos removal enclosure. These machines are not designed to be used

inside an enclosure as this may cause internal electrical components to

become contaminated. This will in turn create a risk of transferring

contamination to maintenance work areas where unprotected personnel will

be at risk of asbestos exposure.

NPU’s should be attached to an enclosure with the main body of the machine

outside the work area, see photograph for example.


5.3 Connecting to a Suitable Power Supply

For the NPU to function at its optimum output, it is vital that it is connected to

the correct power supply.

For the UK a 110 volt power supply is needed and for Europe a 230 volt

supply is required.

When using extension leads, check that the cable diameter is capable of

delivering the required voltage to the machine, excessive extension cables

will ultimately lead to a voltage drop.

If you are unsure if you have the correct voltage available, consult with a

qualified on site technician who will be able to test the power supply for you.

Please see the specification information in section 7 of this document for

more detailed information, amperage and watts etc.

5.4 Fan Switch Operation and Variable Speed Control

The NPU fan is operated by an On/Off Switch and the speed of the fan can be

controlled with the variable speed control which is fitted as standard to all

Beacon Negative Pressure Units.

The switches will illuminate when activated to confirm power is present.

Variable speed controller is operated by turn the control knob in a clockwise

direction for greater fan speed or in an anti-clockwise direction to lower fan

speed. See photograph below.

5.5 Manometer Gauge


A manometer gauge is fitted to all Beacon NPU’s.

This device measures pressure inside the machine in comparison to external

atmospheric pressure outside, the gauge reading is used to determine the

condition of and will indicate to users when the filters are blocked.

5.6 Changing Pre Filters

The chart on manometer readings in the previous section (5.5) can be used to

determine when to replace pre-filters in the NPU.

Always use G4 pre filters to ensure that adequate protection is given to the

HEPA filter, using poor quality pre filters will dramatically reduce the life of

the HEPA filter.

When replacing a pre filter in an NPU, always make sure that the filter pleats

run vertically and not horizontally, see photograph.

5.7 Airflow Loss (Ducting & Roving Heads)

NPU MODEL GAUGE READING – CHANGE FILTERS NPU500 650PA

NPU1200 950-1000PA

NPU2000 750-800PA

NPU5000 700-750PA


Airflow capacity of NPU’s is classified in M3/h (cubic metres per hour).

When using NPU’s on an enclosure, there are factors that may reduce airflow

and must be taken into consideration.

Using exhaust ducting and or roving heads and inlet ducting will have a

significant influence on airflow.

Experiments were carried out in the UK by the HSE, see table below for data.




6. NPU Service and Maintenance

Negative pressure units need to be tested at intervals laid out in current

legislation by either the manufacturer or a company qualified to carry out

testing correctly.

6.1 Daily Checks

NPU’s in operation on site must be visually inspected on a daily basis to

ensure they are running without any problems, mechanical issues etc.

Any problem or failures must be reported immediately to the site supervisor

or foreman.

6.2 Weekly Inspections

Decontamination units, vacuum cleaners and negative pressure units must

be inspection on a weekly basis, these inspections need to be recorded into a

maintenance log record. The information collected on these forms is to be

noted, any problems are to be resolved by trained personnel.

For any major faults found, equipment will have to be returned to the

manufacturer or a suitably qualified company to carry out the necessary

repairs.

All data collected, including faults found, repairs carried out must be entered

into the service log which will be used as evidence that any issues have been

dealt with correctly for inspection or audit purposes.

Please see example maintenance log on the following page.

6.3 Service and Testing

Service and DOP (dispersed oil particulate) testing must be carried by a

qualified company, it is a legal requirement that companies carrying out

servicing and testing of asbestos removal equipment hold a HSE Ancillary

Licence.

Testing intervals can vary from one country to another.

UK – 6 Months

France – 12 Months

Nederland – 12 Months

Italy – 12 Months

Greece – 12 Months

Turkey 12 Months

Australia – 6 Months

New Zealand – 6 Months

When NPU’s have been DOP and electrically tested, a test certificate must be

supplied by the testing company, this certificate must be kept on record by

both the owner of the NPU and by the company carrying the testing.

Testing must be carried out by trained personnel using only calibrated test

equipment.

As the manufacturer, Beacon International automatically issue service

reminders in the UK when your NPU is due for service and testing.

If you have purchased your machine through a distributor, they will notify you

when your equipment is due for its periodic test.
