The Health Risks of Asbestos Poisoning

Strictly speaking, asbestos poisoning is not a medical term but it does broadly describe the range of potentially life threatening diseases someone can contract if exposed to asbestos fibres. Although the different types of asbestos have varying levels of danger, all have the potential to cause disease if mishandled. SafeWorkPro has more information on how to identify asbestos and manage it through an asbestos risk assessment. Regardless of this, the best safe operating procedures begin with a basic understanding of the health risks surrounding asbestos.

Asbestosis

What is it?

Asbestosis is an incurable lung disease characterised by the scarring of lung tissue caused by the inhalation of asbestos fibres. Unlike lung cancer or mesothelioma, people with asbestosis can live for decades after diagnosis but as time passes, the individual’s condition will deteriorate and require more treatment.

Symptoms:

Asbestosis is caused by sharp, minuscule asbestos fibres becoming lodged in the lung tissue. Over the period of 20 to 30 years, the fibres cause inflammation and eventually scarring as the body attempts to heal. The severity of the symptoms depends of the length of an individual’s exposure to asbestos and include:

  • Swelling in the face and neck
  • Shortness of breath and coughing
  • Chest pain
  • Loss of appetite and weight loss
  • Swallowing difficulties
  • Blood in the lung mucus (sputum)
  • Crackling noise in breathing
  • High blood pressure/hyper tension
  • Deformed fingers

Treatment:

Due to the fact that no cure currently exists for asbestosis, the treatment methods commonly offered are designed to manage the symptoms rather than treat the cause. Along with healthier lifestyle and diet changes, supplemental oxygen and antibiotics, several treatment options are available for sufferers of asbestosis.

  • Pulmonary rehabilitation: a long-term treatment that teaches better breathing methods, exercise techniques and stress relief.
  • Prescription medications that ease pain and dilute secretions.
  • Respiratory physiotherapy to remove lung secretions

For more information on asbestosis, check out the Australian Asbestos Network.

Benign Pleural Disease

This is the most common form of disease found in people that have been exposed to asbestos. Benign pleural diseases are usually not life threatening but can cause extreme discomfort and pain, and can be symptomatic of late stage mesothelioma. The four main types of asbestos related pleural disease include:

  • Pleural plaques: these are patches of fibrous thickening that develop between the rib bones and the lining of the lung. Plaques are generally not viewed as a serious health issue but can cause painful and difficult breathing patterns.
  • Pleural effusions: this occurs when fluid is leaked into the space between the lung and the membrane that lines it. Although not life threatening on its own, pleural effusions cause extreme chest pain can reoccur even after treatment.
  • Pleural thickening: this is when the lining of the lung tissue becomes irritated resulting in lesions and swelling. In unusual cases, pleural thickening can be life threatening as it severely disrupts breathing patterns.
  • Pleuritis: this occurs after the lining of the lung tissue (pleura) becomes inflamed causing significant chest and shoulder pain.

In most cases the best treatment for pleural disease is lifestyle changes (ie quitting smoking) and appropriate exercise. If you are experiencing any of these symptoms you should contact your doctor immediately as it may be indicative of lung cancer.

Mesothelioma

What is it?

Mesothelioma is a form of cancer that can take anywhere between 20 and 50 years to display symptoms. It is caused by asbestos fibres that become lodged in the tissue surrounding the lungs, resulting in cellular damage that eventually leads to tumour growth. This is known as pleural malignant

mesothelioma and represents the most common form of this disease. However asbestos inhalation can also cause this cancer to occur in the lining of the abdominal cavity (peritoneal) and the heart (pericardial).

Symptoms:

The different forms of mesothelioma have varying symptoms of which more information can be found out about here. Symptoms, even those displayed in the later stages of the disease’s progression, can be subtle and unnoticeable. Early signs can be so insignificant that even doctors can misinterpret them as a simple ache or illness. The most common symptoms for mesothelioma include:

  • Constant fatigue
  • Loss of appetite and weight loss
  • Chest pain
  • Breathing difficulties
  • Dry coughing
  • Shortness of breath

Current medical research is aimed at finding earlier diagnosis systems but there are several more symptoms that indicate mesothelioma has spread to other parts of the body. These symptoms include:

  • Difficulty swallowing
  • Obstruction of the superior vena cava (a vessel that carries blood into the heart) leading to shortness of breath and facial swelling
  • Low blood sugar levels (hypoglycaemia)
  • Damage to nerves attached to voice box (laryngeal) leading to harsh breathing and speaking

Treatment:

Currently no cure for mesothelioma exists but there several treatment options available that can alleviate symptoms and extend life expectancy.

  • Surgery: this treatment method can be used to remove tumours, alleviate pain for improved quality of life or to secure a biological sample for diagnosis.
  • Chemotherapy: a chemical infusion into the bloodstream that aims to kill cancer cells, reduce the size and spread of tumours and prolong survival. Unfortunately chemotherapy cannot cure mesothelioma and comes with significant side effects including hairs loss, nausea and weight loss.
  • Radiation therapy: this is used to stunt the growth of tumours and has been known to increase life expectancy and alleviate pain. Radiation therapy can be used at any stage of mesothelioma and includes the side effects of skin irritation, inflammation of the oesophagus, fatigue and nausea.

 

Beside mesothelioma and lung cancer, asbestos poisoning has been linked to the following cancers:

  • Prostate
  • Gallbladder
  • Hodgkin’s lymphoma
  • Non- Hodgkin’s lymphoma
  • Kidney
  • Leukemia
  • Gastrointestinal
  • Colorectal
  • Laryngeal
  • Breast
  • Ovarian

How To Identify Asbestos

A key aspect of a safe and complete asbestos risk assessment is the inclusion of a hazardous substance risk assessment form. This is not something that should be taken lightly as asbestos in homes is a real risk in any property built before 1990. Therefore knowing how to identify asbestos is a critical step in any type of asbestos training.

But this can be an expensive option. If you wish to test any material you suspect of containing asbestos, you can contact the National Association of testing Authorities for an independent evaluation. With over 3000 asbestos containing products used in construction prior to 1990, professional consultation and testing is the safest option for the identification of this highly hazardous material. But there are several common characteristics of asbestos containing materials.

Warning signs: look for any warning signs or labels that indicate the existence of asbestos.

Age: any property built before the late 1980’s could contain asbestos. Consult with local authorities, the structure’s builder, previous owners and neighbours.

Fasteners and joints:  check the battens used to to cover the joints between sheets of asbestos containing materials like AC sheeting. Any broken battens, gaps in joiners or loose nails, can indicate the presence of asbestos.

Close inspection: if you have a digital camera with a macro mode function, use it to take a close up photo of the material. Asbestos fibres are microscopic but the strands that are made up of these fibres can often be found clumped together (see left image for example). Note: never break the material apart to check as it could release asbestos fibres into the immediate area. 

It must be noted that these are initial steps and cannot guarantee the total identification of all asbestos materials. For that, an accredited asbestos specialist will need to be engaged.

Hazardous Substances Risk Assessment

Managing risk can be a complicated task especially when looking at a risk assessment for chemicals. This is a whole new ball game for risk management consultants and the harmonisation of regulatory frameworks don’t make this any clearer. The problem hazardous substances (or chemicals) have in high risk construction work is that the

ordinary worker won’t know how to identify the specific elements and compounds that make a substance hazardous, nor have an in depth understanding of the appropriate control measures.

To soften the inherent risks involved to the maximum degree possible, Safe Work Australia and the relevant state regulators require the importers and manufacturers of hazardous chemicals to provide a Safety Data Sheet (SDS) to the people or organisations using their product. The SDS provides the PCBU and workers with information on the dangers involved with a substance, the controls methods and forms of treatment should an incident occur. All this information is vital in the writing of a compliant hazardous substances risk assessment.

A hazardous substance risk assessment form differs from other risk assessment in construction in that it must include information such as the health effects, signal words, precautionary details, control measures and recommended protective equipment that are outlined in the SDS. An example of this in a risk assessment form is below.

That all being said, the underlying elements of a compliant risk assessment for construction, including the hierarchy of control measures, remains largely the same. Hazard and risk identification, the implementation of control measures, the duty of care and review process, all remain core components of a hazardous substance risk assessment.

For more information, read Safe Work Australia’s guide for the preparation of Safety Data Sheets.

The Codes of a Chemical Risk Assessment

Chemistry is complicated stuff and a risk assessment for chemicals is no different. The range of hazardous chemicals used in the Australian construction industry is only overshadowed by the number of risks associated with them. A chemical risk assessment must take all of these inherent dangers into account but understanding every substance or chemical, along with the

associated risks and hazards, is not a reasonably practicable option for most construction businesses.

Therefore the Safe Work Australia provides list of codes used in Safety Data Sheets to explain the various hazards and risks associated with hazardous chemicals. This resource is provides both construction workers and managers with quick and easy to understand explanations of each chemical code and the related hazard.

Your hazardous substances risk assessment should then include these codes in the risk identification process when applicable. The benefit of including this in your chemical risk assessment form is that it not only improves how workers understand the risk involved with hazardous chemical but it also displays an attempt on behalf of the PCBU to ensure a safe working environment.

To improve your chemical risk assessments along with your workplace health and safety, you can access a full list of the codes here.

Working in Confined Spaces Risk Assessment

Whether you work in an office or under the sun, sometimes everyone feels like they’re working in a tiny, unescapable box. When it comes to high risk construction work however, there is a specific meaning for working in confined spaces. This affects the many different factors a confined spaces risk assessment must take into account when conducting hazard management.

Regulation 5 of Australia’s Work Health and Safety Regulation defines a confined space based on to the hazards associated with it. Under this definition and under the codes of practice outlined by Safe Work Australia, a confined space means an enclosed or partially enclosed space that:

o is not designed or intended primarily to be occupied by a person; and

o is, or is designed or intended to be, at normal atmospheric pressure while any person is in the space; and

o is or is likely to be a risk to health and safety from:

  • an atmosphere that does not have a safe oxygen level, or contains contaminants, including airborne gases, vapours and dusts, that may cause injury
  • fire or explosion, or harmful contaminants
  • engulfment.
  • examples may include vats, tanks, pits, pipes, ducts, flues, chimneys, silos, containers, pressure vessels, underground sewers, wet or dry wells, shafts, trenches, tunnels

Many of the generic risks involved with working in confined spaces include:

o loss of consciousness, impairment, injury or death due to the immediate effects of:

  • airborne contaminants
  • fire or explosion from the ignition of flammable contaminants
  • difficulty rescuing and treating an injured or unconscious person

o asphyxiation resulting from oxygen deficiency or immersion in a free-flowing material such as grain, sand, fertiliser, water or other liquids.

An effective and compliant confined space risk assessment example will take notice of these generic but identifiable hazards:

  • Restricted entry or exit
  • Presence of harmful airborne contaminants
  • Unsafe oxygen levels caused when oxygen in the atmosphere is:
  • Fire and explosion
  • Unstable substances that risk engulfment
  • Uncontrolled introduction of substances
  • Contact with biological agents
  • Exposure to mechanical hazards
  • Contact with electrical hazards
  • Skin contact with hazardous substances (this will require a hazardous substances risk assessment)
  • Noise
  • Manual tasks
  • Radiation
  • Environmental hazards

For more details on these hazards and the related risk control measures, read the SafeWorkPro Blog.

Control Measures for Confined Space Safe Work Procedure

In previous articles on the SafeWorkPro Blog, we’ve looked at the risks and hazards of working in confined spaces. But what good is a risk if there no control measures?

Below is an extensive list taken the codes of practiceby Safe Work Australia, that outline the various control measures available to construction workers and PCBU’s involved in high risk construction workBefore conducting work in a confined space, it is strongly recommended that all duty holders consult this list, and more importantly, the relevant codes of practice.  The control measures outlined by Safe Work Australia include:

Entry permit: A PCBU must not allow or direct a worker to enter a confined space to carry out work unless the person has issued a confined space entry permit for the work. A space entry permit must be completed (in writing) by a competent person and specify:

  • specify the confined space to which the permit relates record the names of persons permitted to enter the confined space and the period of time that the work will be carried out
  • set out risk control measures based on the risk assessment, and contain space for an acknowledgement that work in the confined space has been completed and all persons have left the space.

 

Isolation: All potentially hazardous services should be isolated prior to any person entering the confined space. These services may include piping, vents, drains, conveyors, service pipes, machinery, plant, electrical equipment or fire protection equipment.

  • Physically tag, lock, close or blank hazardous service
  • Removal of valve, spool piece or expansion joint in piping that leads to confined space
  • Remove energy source to any agitator, fans or other moving parts in a confined space (if energy source cannot be removed consider choking, wedging, chaining or removing any moving parts)
  • Reduce any device with stored energy including hydraulic, pneumatic, electrical, chemical, mechanical, thermal or other types of energy, to a condition of zero energy

 

Atmosphere conditionsa safe atmosphere has a safe oxygen level, is free of airborne contaminants o has concentrations below their allowable exposure standard, has concentrations of flammable gas or vapour below 5% of its LEL. Control methods include:

  • Purging: use an inert gas, such as nitrogen, to clear flammable gases or vapours out of the confined space. Following purging, the space should be ventilated with sufficiently fresh air and any removed contaminants should be expelled to a location that presents no further risk. Before conducting work in the confined space, atmospheric testing should be carried out
  • Ventilation: may be necessary to establish and maintain a safe atmosphere and temperature for as long as work is conducted in the confined space
  • Natural ventilation: only if the confined space has sufficient openings and the source of fresh is not contaminated by any exhaust or other pollutants
  • Mechanical ventilation: use local exhaust ventilation (LEV) for localised contaminant generation (eg extraction of welding fumes). LEV should be monitored during operation and have controls clearly identified, tagged and protected
  • Dilution ventilation: air must be introduced in way that ensures effective circulation through the confined space with openings, contamination level and area layout put into consideration

Respiratory protective equipment (RPE)if it is not reasonably practicable to ensure a safe oxygen level, remove the confined space of contaminants or when there is an unknown concentration of a hazardous substance is present, then respiratory protective equipment must be worn.

  • AS/NZS 1715: Selection, use and maintenance of RPE

 

Safety monitoring: a standby person must be assigned to the vicinity before a worker enters a confined space to continuously monitor the wellbeing of those inside the space.

  • The standby person should be aware and understand the risks inside the confined space and be able to recognise signs and symptoms of distress that workers in confined space may experience (reg 69)
  • The standby person should remain outside the confined space and do not other work that impedes their monitoring duties
  • A required rescue and safety equipment should be available to standby person
  • The standby person should have the authority to order an evacuation and never enter the space to attempt a rescue
The SafeWorkPro Blog has more information on confined spaces including how to manage the related hazards and how to define what constitutes a defined space.

What is Job Safety Analysis?

Did you know that panthers and leopards are the same animal? No jokes. Only their fur coats are different, everything else is the same. Believe it or not, job safety analysis forms are similar (minus the claws, teeth, agility and general awesomeness).

Otherwise known as a risk assessment or a job task analysis, job safety analyses (JSA for short) aim to identify hazards and implement measures that will control or at least minimise the risk involved in construction work. Job safety analysis forms come in a variety of types but all share the common traits. The below job safety analysis template comes from the Victorian WorkCover Authority and gives you an idea of correct layout.

As you can see from the above job safety analysis worksheet, there are four parts to a good JSA template.

1: Classify the tasks: along with everyone involved in the high risk construction work, write down each of the steps that make up the job.

2: Hazard and risk identification: besides each step, write down what injuries or health threats are involved.

3: Document the control measures: next to each hazard assessment, specify what control measures will be used to eliminate or reduce the risk of injury or ill health.

4: Distribute responsibility: outline who is responsible for the implementation of each control measure.

One more point that you’ll need to remember. If an incident does occur in the workplace that results in injury or ill health, your job safety analysis could very well be used in court proceedings. This means every duty holder must sign off and review the job safety analysis worksheet should safety conditions change.

So it’s all pretty similar stuff. Panther or leopard? Risk assessment or job safety analysis? Same things, different names.

Construction Safety Software: a saviour in disguise?

The internet has fundamentally changed the way we do business. Files can be instantly transferred across the world, entire encyclopaedias of information are just a click away and social media gives your target market a voice. We live in a brave new world that is both deeply interconnected and highly competitive but there is one area where recent leaps in technology are yet to touch.

Risk assessments are as much a part of high risk construction work as hard hats and steel cap boots. But whereas other industries have embraced the advantages offered by technology, safe operating procedures in Australia are still stuck in the past. Doing a risk assessment online seems like something that would have become industry standard by now, but in reality the paper-based method, although out dated and inefficient, is still the main method of handling risk and compliance in Australia. This is a problem because as OHS legislation Australia tightens and regulations intensify, the risk management process becomes far more time consuming and more costly. This is bad news for your competitiveness.

Construction risk assessment software is the solution but what it is and how it should be used properly, remains unresolved.

Until now.

Current examples of construction safety software merely provide you with a digital copy of safe work method statements and other risk assessment forms. This doesn’t do much in terms of streamlining the risk assessment process and reducing these costly drawbacks. The paperwork, even in a digital form, still needs to be completed, copied, printed, signed and stored for future compliance requests. The Risk assessment software SafeWorkPro has developed puts this entire process into one easy to use tool available on any smart phone or tablet device.

Check out how SafeWorkPro can take your construction business into the future.

The Perfect Mix: Risk Assessment Documents and Push Notifications

On a safe work site, the core ingredient will always be good communication between workers and employers. However, while almost one third of construction workers agree that conditions in their workplace stopped them from working safely, the figure reported by their employers was much lower. This gap in communication can be pinned down on two major issues; not being able to be in 101 places at once, and an inefficiency in the traditional system of paper risk assessments. In response, SafeWorkPro is bringing you much needed change for high risk construction work. We want to communicate with you how our way to resolve these issues with our epic new push notification feature!

1: Not being able to be in 101 places at once

Particularly on huge sites with numerous trades, monitoring risk assessments for any high risk assessment risk ratings can seem like a job of epic proportions. While you are likely already managing this task as fast as humanly possible, there is only so much you are physically capable of completing and you cannot be in 100 places at once. Technology is therefore the most practical solution to your efficiency problem, and no we don’t mean cloning yourself.

SafeWorkPro is bringing a much more reasonable and cost-effective answer in the form of push notifications for our mobile applications! This feature brings a whole new level of simplicity for you to the risk assessment process. Push notifications immediately display on all admin devices with the name and place of a worker who has submitted a risk asessment containing a risk rating above 15. Not only is this saving you the time and effort of individually scanning all safety documents for the warning signs of danger, but it is also improving your emergency response rates. The immediacy of the notification allows you to prioritise your duties, and attend to potential work safety emergencies as they appear.

2: Traditional methods being inefficient

Our key to solving your second dilemma lies in our computerisation of your safety documents. A major perk of this is the softwares ability to scan your workers documents for things such as a high risk assessment rating over 15. Seeing this figure would be enough to trigger your safety alarm bells, but spotting it amongst a stack of paperwork over a mile high poses a greater challenge. Allow our technology to sift through the paperwork for you!

So instead of feeling overwhelmed by safety procedures and paperwork, try turning to SafeWorkPro to improve communication of safety issues on your worksite.

What is Meant by Risk Assessment Software?

Keeping up with technological advancements in the field of hazard and risk management is tiresome and at times just too much of a hassle. But turning a blind eye to developments in the risk analysis process will come at cost to business productivity and even worker safety.

Risk assessment software is one such development and it comes in many forms with some being more useful than others.

This is all good and well but what is meant by risk assessment software? Or in other words, what is risk assessment software?

Otherwise known as construction safety software or safety compliance software, this digital tool is an alternative to the traditional, paper-based risk management process. Compliance with OHS laws and regulations is a requirement that no construction business can afford to neglect but it doesn’t need to come at the cost of productivity. This is the purpose of risk assessment software – to streamline the risk management process and reduce just how much time is spent on software-based risk assessments.

The Benefits of Software

Software like SafeWorkPro automates the risk management process through an intuitive digital form. This form organises risk assessments into a step-by-step process that can be completed within two minutes. Quicker than the paper-based method, this approach also saves previous risk assessments for future audits and allows managers to monitor their workforce’s safe operating procedures.

Successful risk assessment software basically digitalises the involved paperwork in a way that anyone, regardless of technological know-how, can use easily. Now there’s obviously a lot more too risk assessment software than that but hopefully this article gives you a basic understanding of what the technology actually is. If you would like to learn more about the benefits the SafeWorkPro software can offer your business, read our case study – the savings will surprise you.
