Does your site need better noise, air or fumes control?

Our Brisbane client came to us with a problem for a sensitive project at Greenslopes Private Hospital. They needed to demolish the existing outpatient reception area and required effective hazard control measures, such as RVT Group's dust control system to be put in place to protect air quality.

The reception was right next to the accident and emergency trauma area (which could not be interrupted from operating 24 hours 7 days a week). With only a thin temporary partition erected in between the two areas, maintaining a completely sterile and hospital grade air quality (whilst conducting a demolition next door), was always going to be a challenge.

RVT Group supplied a dust extraction system comprising a Ventex 300M fan and Dustex Wandafilta Plus (and associated ducting), to create a negative pressure system inside the demolition zone. What this method achieves is an air flow at every ingress point, moving to push the dust away from the sterile areas and back to the capture point.

The fan system creates this vacuum and pushes through the three stages of filtration to deliver clean healthy air. The system also protects against the spread of Crystalline Silica particles (the cause of Silicosis) and dangerous mould found in old buildings. Additionally, it filters out germs and microbes from infectious diseases.

Therefore, not only are the clinical workers and patients protected, but the construction workers and demolition crew are able to go home safely. With real time dust control monitoring in place, we were able to prove that our equipment prevented any dust ingress to the operating hospital area. Importantly, the demolition crew were looked after through the provision of clean air, which is a key component of workplace health and safety.

The QLD Gallery of Modern Art is a large art museum located within the South Bank precinct of Brisbane, Australia.

The installation of a new exhibition included extensive fibreglass welding works. Fibreglass welding fumes can be harmful if inhaled, and particles can permanently damage the eyes and lungs. An isolated area was constructed where the welding was to occur, and extraction of the fumes was needed.

The team at QAGOMA approached RVT Group for help. They were seeking control and efficient extraction of the fumes that would be produced during the welding - for the outcome of reducing the risk of fume exposure for the gallery workers.

If inhaled in sufficiently large quantities, exposure to fumes generated by fibreglass welding can be extremely harmful. It should be avoided as much as possible. as these fumes can damage lungs, eyes and even the nervous system.

The art gallery conducted welding in a sealed and isolated temporary enclosure. The gallery staff working on the art installation were close by, so keeping them safe was the major priority.

The RAVEX Carbon Fume Filtration Kit was commissioned to extract the fumes out of the area. This was very effective and brought the enclosure under negative pressure meaning that there was no risk of fume migration to other areas of the gallery.

RVT Group provided Raptor Pro for the client. The Raptor Pro is adaptable for all extraction needs and was adapted to suit fume extraction.

It uses a 2-stage filtration system, with the second stage being an activated Carbon filter. This kit is highly effective in filtering and extracting fumes, from over 30-meters away into a low traffic area outdoors. This provided the personnel onsite protection from fume exposure.

The team onsite was impressed with the ease of operation and effectiveness of the unit.

A large commercial builder in Melbourne approached RVT Group for help with the control and monitoring of diesel fume hazards inside a warehouse under construction.

The building under construction had reached the internal fit-out stage, where the workers were having to operate diesel machinery in a semi-enclosed area, creating the risk of diesel fume exposure. RVT Group provided two centrifugal fans to ventilate and supply fresh air to the work zones.

Exposure to diesel particulate fumes can be damaging to the health of workers on site due to the very high risk of carbon monoxide poisoning — This is especially a challenge if the machinery is being operated indoors.

This site was partially enclosed and so there was a risk of fume build up inside the work zone. Hence the requirement for forced ventilation. This ventilation would need to feed fresh air into the work zone to dilute the contaminated air and to protect the health of the workers inside the building.

The 450S is a powerful Centrifugal fan, capable of a 20,400m3/hr airflow, making it able to provide high airflow through long duct runs. This makes it ideal for forced ventilation or extraction from confined areas such as basements, shafts, tunnels, and sewers.

Two of the 450S fans were placed onsite to assist in the ventilation of the area, along with a RAVEX Portable Multi-Gas Detection Unit. This detection unit was being used to monitor the diesel fumes and would alarm if the exposure risk reaches a hazardous level for the workers in the area.

The client was impressed with the efficient service and consultancy provided by RVT, along with the complete solution and monitoring package to address the health hazards on site.

Our Client and business partner Trieste Global needed a solution for dust control for the cutting of tiles on multiple floors of the Mirvac Construction site at 80 Ann St, Brisbane. This is the new state of the art building which will become Suncorp's new home in Queensland. Their work involves cutting and moving tiles around, which creates a lot of dust and noise. As always we applied our ‘Capture, contain and control’ methodology.

Cutting tiles creates fine dust containing the deadly respirable silica, this cannot be left to spread on the site and harm contraction workers.

RVT Group recommended a Dustex Raptor unit coupled with duct and capture hood, installed in our Soundex Multi Purpose enclosure.

The capture hood and Raptor unit’s three stage HEPA filtration system ensures the complete capture of the dust. Whilst the Soundex enclosure ensures that we can contain dust in the area, and the multi adjustable fan system of the raptor ensures control of the negative pressure are to prevent any ingress and spread over the site. All in all RVT Group provided a complete solution.

Woolworths Group supply chain arm, Primary Connect, has commenced building works on its new $184M, 42,000 square metre Distribution Centre in Heathwood, southeast Queensland - This centre will distribute to over 200 stores across QLD and NSW.

Primary Connect was completing machinery fit out works in very close proximity to a meat processing environment. The use of the diesel tele-handler unit created the risk of fumes and particulate contaminating the neighbouring food/food processing equipment, which potentially could seriously jeopardise the health of consumers Australia wide.

The contractor approached RVT seeking controls for the diesel particulate that would be produced while the machine was operating in view of reducing the risk of fume contamination.

Proximity and direct exposure to diesel exhaust can irritate the eyes, nose, throat, and lungs and can be harmful to asthma sufferers. Extended exposure can cause light-headedness and nausea. Extreme levels of diesel exhaust exposure can lead to carbon monoxide poisoning.

In the circumstances of this project, the risk of food contamination was at the forefront of the contractor’s mind, hence the reason for the commissioning of the filtration system. Contaminated food would be detrimental to consumer health as well as the reputation of the brand.

The Client hired a RAVEX Diesel Filter M60 Twin Kit which is compatible with most small mobile plant with engine sizes up to 100kW. This kit is highly effective and can remove 95% of particulate from diesel engines. The personnel onsite were protected from diesel fume exposure, as well as the customer base of the food processing plant.
