Airborne dust awareness, where do I stand? - Mark Shepherd
Understanding what airborne dust is, its potential health effects and how to manage dust in all areas of the workplace is fundamental to ensure that the respiratory health of your workforce is protected.
Generating potentially harmful levels of respirable airborne dust is not confined to production-based tasks within an operation. Engineering and maintenance tasks also have the potential to expose tradesmen and operators to respirable dust that can cause lung disease. Many of these tasks are also often conducted without the need for respiratory protection being taken into consideration.
Occupational dust disease is 100% preventable, and the key to workers making smart choices about their health is education.
This presentation is a generic version of the Airborne Dust Awareness sessions that have been rolled out to thousands of mineworkers in the NSW coal industry recently and has resulted in positive behavioural change in and around the workplace.
As industry leaders, we all need to understand the risks before we can identify them, then eliminate or control them.

Crystalline silica exposure in the construction industry
Crystalline silica, also known as quartz, is a natural component of sand and granite that is commonly found in construction materials. Exposure to crystalline silica dust can cause silicosis, a lung disease where scar tissue forms and reduces lung function. Construction workers are at risk of exposure during activities like sandblasting, jackhammering, cutting concrete, and tunneling. OSHA has regulations to limit crystalline silica exposure and requires employers to provide protective equipment and engineering controls to prevent workers from breathing in harmful silica dust.
What is occupational hygiene?
Occupational hygiene aims to prevent illness caused by workplace hazards. It does this through recognizing, evaluating, and controlling hazardous agents via a multidisciplinary approach involving chemistry, toxicology, physics, biology, engineering, and law. Hazards include chemicals, physical agents like noise and vibration, biological agents, and ergonomic risks. Risk is determined by assessing the hazard and level of worker exposure. Controls follow a hierarchy starting with eliminating or substituting the hazard, then using engineering controls, administrative controls like safe work practices, and finally personal protective equipment. Occupational hygienists play a key role in anticipating hazards, conducting exposure assessments, and advising on prevention strategies to protect worker health.

Fires on mobile plant refuelling (Ross Stutchbury)
This document analyzes fire incident data on mobile plant from July 2014 to March 2019. It shows trends in fires by month, quarter, sector, and potential heat and fuel sources. Investigation findings identify failures to identify risks, implement safe work systems, properly supervise work, provide adequate training, and use fit-for-purpose equipment. Recommendations focus on risk assessment, supervision, training, equipment design, and procedures to prevent fires during refueling. Specific case studies on refueling truck and grader fires provide additional investigation findings and recommendations.
Mobile plant rollovers and collisions (Bill McGlynn)
This document discusses several incidents involving mobile plant rollovers and collisions at coal mines. It summarizes three cases where dozers preparing shot ground rolled over due to a lack of situational awareness. Common factors identified were inadequate risk assessments and operators continuing work when unable to maintain situational awareness. Four light vehicle rollovers are also examined, with the primary causes found to be operators not focusing on their task or being distracted. Finally, the document outlines planned assessments of roads, traffic management, and operator competency at mines to improve safety.
Metropolitan colliery gas (Dave Gordon)
Workers were evacuated from Metropolitan Colliery on March 21st 2019 after gas levels rose in the longwall return. At 6:00pm, high CO2 was detected at the longwall face, causing operations to stop. At 7:15pm, all underground workers began withdrawing as CH4 levels continued rising. By 8:45pm all workers had been withdrawn and accounted for on the surface. Gas levels in the longwall return reached 16.1% CH4 and 15.9% CO2, while levels in the main upcast shaft were 3.01% CH4 and 4.16% CO2. Workers remained out of the mine for seven days as 2.9 million cubic metres of 38% CH

Where do I stand for fire protection on mobile and transportable equipment an...NSW Environment and Planning
The death of a truck operator in the USA in 2018 at a Peabody mine as a result of a fire highlights the importance of installing fire suppression systems. Firestorm has been involved in the world's largest retrofit of fire supression systems on buses. While buses may be considered simple for fire protection versus a mining machine, buses can carry up to 100 passengers and typically there is a lack of mechanical protection with the majority of the body made of fibreglass, wood and plastics that burn very quickly and are highly toxic. The risk for multiple deaths is therefore a much higher factor compared with a mining machine with one operator. The risk assessment required in AS5062-2016 needs to consider the egress paths available for an operator/passenger to safely evacuate the machine and consideration for actuators and fire extinguishers along this path.
Changes to laws in 2016 required the removal of PFAS and PFOS in both Queensland and South Australia with penalties noe effective for non-compliance. Several NSW mines have been put on notice by the Environmental Protection Agency (EPA) to prevent further contamination of waterways. Firestorm is now moving away from exposing our own people to PFAS/PFOS systems to ensure we are providing best practice even though laws are not yet in place for NSW. This presentation looks at what it means if you choose to move away from PFAS/PFOS systems.The culture of hydraulic safety - Kyle Probert
The document discusses the culture of hydraulic safety. It notes that hydraulic systems are not supposed to leak but that some work conditions make leaks difficult to prevent. It acknowledges that in the past there was a tendency to just keep machines running despite leaks due to lack of time and resources to fix issues properly. However, it advocates moving to a safety culture where procedures are followed willingly through leadership, engagement, and providing workers with the tools and processes to work safely rather than just policing safety issues.
Demolition of a former mine site - Luke Egan and David Wood
Liberty Industrial was engaged by Glencore to complete the demolition of a former coal preparation plant on a redundant mine site in Teralba NSW. While the mine was non-operational and formerly underground, many of the mine systems, plant pass-in and permitting requirements were based on on the site being an operational underground mine. Both Liberty Industrial and Glencore worked together during the planning phase to ensure that both parties understood the work, the design-related aspects and aspects of the Glencore systems that were not appropriate for this type of work. The teams worked together to develop a risk-based approach that satisfied the Glencore internal systems while maintaining efficient execution processes.

Waterproofing Changes in Victoria
The Building Act 1993 remains, but the Building Regulation 2006 will be replaced by the Building Regulations 2017, expected to be legislated around September. Key changes affecting the waterproofing industry include Part 13, which mandates inspection prior to covering a waterproofing membrane in any wet area.
The regulations remain consistent in other areas affecting waterproofing, such as the adoption of the NCC and relevant Australian Standards, methods of assessment of compliance, material testing, and compliance certificates.
The VBA confirms that only a registered Building Practitioner can authorize compliance of waterproofing works. Subcontractors who are not registered cannot authorize compliance. Although they can state that they have complied with the relevant standards, liability lies primarily with the registered builder, now shared with the Building Inspector or Surveyor for wet areas.
QBCC Tradie Tours
Waterproofing is consistently one of the most common defects reported to the QBCC, with mistakes being costly. In June 2017, the QBCC presented ten waterproofing seminars throughout Queensland, dedicated to waterproofing and tiling issues with a focus on preventing waterproofing defects. Approximately 1000 builders, waterproofers, certifiers, and tilers attended these seminars.
Bayset’s Training & Quality Manager, Frank Moebus, provided in-depth information about avoiding installation problems. The Tradie Tour received positive feedback from the industry.

Comprehensive Guide to Balcony Waterproofing Repairs
Addressing Leaking Balconies, Roofs, and Rooftop Terraces
Leaking balconies, roofs, and rooftop terraces can cause catastrophic damage to structures below. Water leaks may cause not only aesthetic and superficial damage but can also compromise the structural integrity of the building envelope. If a failed waterproofing membrane is the cause, re-grouting or surface sealing is merely a temporary fix. Such band-aid methods will eventually fail, causing cracks in tiles, grout, and membranes as the balcony moves.
In many cases, failed membranes require a complete strip-off, structural repairs if needed, reinstallation of waterproofing, and a new finish surface. Key considerations in this process include the strength of the subfloor and screed, presence of substrate dips and hollows, correct balcony slope and fall, window and door frame installation, door threshold sealing, adequate drainage, and the potential for underlying pipe leaks. Existing tiling and expansion joints should also be assessed to determine their role in the balcony failure.
Waterproofing Preparation
Proper preparation is critical for any waterproofing membrane installation. The substrate must be clean, free of dirt and other contaminants. This involves vacuum cleaning and/or diamond grinding to ensure a smooth, dry, and debris-free surface. In some cases, washing the substrate may be necessary.
Waterproofing Detailing
Before installing a waterproofing system, construction features that interrupt the membrane layer must be adequately protected and sealed. This includes:
Perimeter Upturns: Attachment points for railings and balustrades, joints between horizontal and vertical surfaces, and structural and expansion joints. Sealant should be applied 15mm wide to all junctions, reinforced with polyester or fiberglass mat to a DFT of 1.2mm, 100mm above finished floor height, or 25mm above the water line. The membrane system should be installed 200mm onto balcony floor areas.
Door/Window Step Downs: Similar to perimeter upturns, apply sealant 15mm wide to all junctions, reinforced with fiberglass mat to a DFT of 1.2mm, ensuring the membrane system is installed 200mm onto balcony areas.
Drains & Floor Waste Details: All floor wastes should have a recessed leak control flange installed, primed with appropriate primer, and the membrane system installed as per specifications.
Waterproofing Installation: Australian Standards
The installation of a Class 2/3 waterproof membrane system to external concrete must comply with AS 4654.2. Key considerations for installation include:
Installation Conditions: Avoid installation in extreme temperatures (below 10°C or above 35°C) to prevent accelerated or decelerated cure times.
Type of Membrane: Use a flexible waterproofing membrane capable of withstanding normal cyclic fluctuations and ponding water.The Late Samuel Sekyere Safo-Ankoma Funeral Booklet

Advancing Waterproofing Expertise with AIW
Waterproofing Melbourne and beyond, the Australian Institute of Waterproofing (AIW) is proud to introduce an innovative commercial waterproofing course. Developed in collaboration with the Master Builders Association Vic, this course, led by Andrew Golle, is tailored for project managers overseeing balcony waterproofing, roof waterproofing, and concrete repair. Paul Evans emphasizes the critical nature of these roles in preventing costly post-construction issues. Private sessions for building supervisors are now available, addressing common mistakes due to poor applications and cost-cutting measures.
The course covers essential topics, including product selection, surface preparation, and the importance of basement waterproofing. Paul Evans highlights the recurring problems seen in the industry, where inadequate training and oversight lead to significant issues, from retaining wall waterproofing to lift pit waterproofing.
In response to these challenges, the AIW is developing a "Below Ground Waterproofing Standard" specific to Australia, inspired by UK standards. Paul Evans calls for industry-wide collaboration to ensure the standard encompasses diverse methods and materials, ultimately enhancing the quality and longevity of waterproofing work.
By equipping supervisors and builders with the right knowledge, AIW aims to improve the overall standard of waterproofing practices, reducing the risk of failures and the subsequent mental and financial stress on homeowners. This proactive approach is crucial for the sustainability and reliability of waterproofing in construction projects across Australia.sim owner details | +923099554040 | sim owner details pakistan
