AGENDA
• Dust Exposure Collect it – Deal with it – Manage it
• Conclusion A Safe jobsite is a productive jobsite – Hilti Solutions
9
• According to the HSE, there are in excess of 5 million users of hand-held power tools exposed to HAVS in the workplace in the UK alone
• Around 1 million workers are exposed to levels of vibration above the
Exposure Limit Value (ELV) The absolute maximum level allowed. • Over 300,000 are suffering from advanced symptoms of HAVS • Each year, HAV accounts for approximately 3,000 new claims for Industrial
Injury Disability Benefit, the greatest number being in the construction industry
Relevance of HAV to the construction industry

• Vibration transmitted to the hands and arms through use of hand-held powered work equipment
• Too much exposure can lead to Hand-arm Vibration Syndrome (HAVS) and Carpal Tunnel Syndrome
• Those most at risk are regular operatives of high-vibration tools over extended periods of time
• For some it may take only months of exposure for symptoms to appear, for others it may take years
Hand-arm Vibration (HAV)
• HAVS or “dead hand” affects the nerves, blood vessels, muscles and joints of the hand, wrist and arm • It includes “vibration white finger”, which can cause severe pain in the affected fingers • Progressive disease, categorised into three stages, believed that the first can be reversible, but after that it is for life, severely affecting quality of life through pain and lack of grip strength
Hand-arm Vibration Syndrome
Carpal Tunnel Syndrome • Carpal Tunnel Syndrome is a nerve disorder which may involve pain, tingling, numbness and weakness in parts of the hand

WHAT CAN YOU DO TO REDUCE THE RISK?
• Keep warm, especially hands – wear gloves and extra clothing when it’s cold
• Don’t smoke or at least cut down first before and whilst at work – smoking affects blood flow
• Exercise your fingers and hands to improve good blood flow
• Do not use more force than is necessary when using tools or machines
• Try to avoid long periods of using equipment without a break – short bursts are better
• Keep your equipment in good working order - ask your Supervisor to make sure it’s properly serviced
• Do not use worn or damaged inserts (points, chisels, drill bits etc)
• Just because it doesn’t shake, it doesn’t mean that it won’t work • Let the tool do the work
• Hold tool in a stance which allows good balance • Hold tool below shoulder level where possible • Restrict the contact pressure to a level where the tool function most effectively • Always grip both handles and restrict grip force just sufficient to hold tool securely
TOOL HANDLING – DRILLING AND BREAKING
• Always use low vibration side handle
• Ensure that you have been trained to use grinders and you have a valid certificate
• Reciprocating Saw - an alternative method to grinding
• Clamp adaptor reduces vibration
TOOL HANDLING – CUTTING & GRINDING
Self re-sharpening: • Constant high performance • Polygon: Less sticking
Wear marks: • Control inserts sharpness • Maintains drilling time / performance
MONITORING AND MEASURING HAVS
EAV
‘Exposure Action Value’
The ‘Exposure action value’ (EAV) of 2.5m/s2 the safer limit that can be worked to without any additional controls in place.
EAV allows a total of 100 points a day
ELV
‘Exposure limit Value’
The ‘Exposure Limit Value’ (ELV) of 5 m/s2 is the absolute maximum level allowed and only where additional controls are in place.
ELV allows a total of 400 points a day

REDUCING THE RISK OF SILICA DUST ON –TOOL DUST EXTRACTION SYSTEMS
Awareness Presentation
RELEVANCE OF DUST TO CONSTRUCTION INDUSTRY • Over 500 construction workers are believed to die from exposure to silica dust
every year • Dust could be ‘the next asbestos’ for the construction industry. • The fee payable by duty holders found to be in material breach of the law is £124
per hour • Silica dust can be extremely hazardous when inhaled over long periods of time or
in large quantities.
SILICA DUST Silica is one of the most common naturally occurring elements on the planet. Silica, the mineral compound silicon dioxide (SiO2), is found in two forms -- crystalline or noncrystalline (also referred to as amorphous). Sand and quartz are common examples of crystalline silica. (Silica-safe, 2015) The hazard arises when the elements are disturbed – by drilling, cutting, grinding and chipping. These processes break up the material and allow the crystalline particles can then enter the respiratory system. This is commonly called respiratory crystalline silica (RCS)
WHY IS DUST A PROBLEM IN CONSTRUCTION? • Produced by many construction processes (e.g. drilling, chiseling, slitting, sanding, grinding…)
• Many base materials contain hazardous material (e.g. silica/quartz in concrete, mortar, bricks & blocks, wood dust in hardwood, softwood, MDF and chipboard)
• All EU countries have legal workplace exposure limits (WEL) for different dust types: Inhalable
Dust Respirable Dust
Silica (quartz) in Respirable Dust
UK COSHH Regulations 2002 10 mg/m3 4 mg/m3 0.1 mg/m3
HOW MUCH DUST ?
To give an example this image shows the maximum amount of silica you can inhale safely over a normal working day.
THE DANGERS OF DUST EXPOSURE

Types of dust Inhalable dust Gets into the mouth and nose
Thoracic dust Reaches the upper respiratory area
Respirable dust Reaches the finest parts of the lungs (alveolar)
HSE GUIDANCE ON DUST
ASSESS THE RISK • The Task – the more high energy activity's e.g.
cutting breaking the more potential for dust creation
• Work area / Environment • Time to completion • Frequency of activity's
CONTROL THE RISK • Pre cut materials • Other methods of working e.g. direct fastening • Water suppression • On tool extraction - local exhaust ventilation (LEV) • Respiratory protective equipment (RPE)

REVIEW THE CONTROLS • Are controls sufficient and effective • Maintenance of control equipment • Review controls with workers
Areas we will look at
• Effective on tool extraction • Maintenance of on tool extraction system
• Alternative methods
CHOOSING ON-TOOL EXTRACTION On-tool Extraction is a system.
Think carefully about key parts when selecting: § Inserts / Consumables
§ Capture Hood
§ Extraction Unit / Vacuum
CHOOSING ON-TOOL EXTRACTION
Tool/Consumables Check that these allow effective removal of the dust
CHOOSING ON-TOOL EXTRACTION Capture Hood: Most important part. Can be designed in or retro-
fitted. Check it: § Is designed for the tool and the work being done. § Sits as close as possible to the work surface
when in use. § Is easy to use and does not interfere with the
work unnecessarily.
CHOOSING ON-TOOL EXTRACTION Hose: Check: • It is of the right diameter and length • for the work and the extraction unit. • It fits securely to both the hood and unit. No tape!

HSE RECOMMENDATIONS
• The most reliable solution for mineral dust
• Filter efficiency 99.9% plus
automatic cleaning function prevents filter clogging
• Easy to handle and maintain • Versatile - can also be used for
wood dusts
• Highest filter efficiency 99.995% • Mineral dust builds up quickly
and cannot be cleaned • Filter performance deteriorates
quickly and without warning • H-class filters must be changed
regularly and cannot be removed without specialist tools

DAILY CHECKS FOR ON TOOL EXTRACTION § Damage to parts of the system such as the hood or ducting. Repair or replace straight away.
§ Replacing worn cutting discs etc
§ Maintain the extraction unit’s flow of air.
§ Check the airflow indicator (audible alarm) and any built-in cleaning mechanism works properly.
§ Follow the manufactures instructions.
§ Replace filters when needed.
§ Clean the equipment regularly (e.g. wipe down). Do not let dust build up on working parts.
USING ON-TOOL EXTRACTION § Following the method of work and manufacturer’s instructions
§ Using the tool in the right way – e.g. move a grinder in the direction of the blade’s movement, not against it.
§ Ensuring the capture hood is as close as possible to the work surface § A good connection to both the capture hood and extraction unit. Use an adaptor if needed, not tape.
§ Emptying the extraction unit regularly. Use disposable waste bags. Seal and place in the right waste container. Do not empty these bags to recycle them.
§ Keeping the collected dust dry. Some extraction units are designed for both dry materials and liquids. Using them in this way when they are part of an on-tool extraction system can reduce the airflow needed for on-tool to work.
MAINTAINING ON-TOOL EXTRACTION • Daily checks are not enough to ensure that on-tool extraction remains effective over a long
period.
• A competent person should thoroughly examine and test all individual parts of the system(s) for damage, wear & tear at least every 14 months to ensure it meets the Manufacturer’s Technical Performance specifications.
• More frequent testing may be needed if regular wear and tear could limit the effectiveness of the system more quickly.
