Action against N.S.W. Mine Contractor

A contractor at the Mount Arthur coal mine near Muswellbrook has committed to spending nearly $500,000 in undertakings after a worker was injured in a fire.

The worker received burns to his head and upper body when a fire started while he was refuelling a diesel-powered tyre handler vehicle. Due to a series of failings, diesel fuel leaked and caught fire.
Following regulatory action, the NSW Resources Regulator has accepted an enforceable undertaking from tyre contractor Otraco International Pty Ltd after the incident on 10 August 2017.

NSW Resources Regulator Acting Chief Investigator Andrew Tull said the company will pay at least $458,219 including the funding and delivery of safety and community projects at a minimum cost of $385,570.

Chemical Spill at NSW Sewerage Plant

Lithgow's hazardous materials team was called to a chemical spill at Wallerawang Sewerage Plant. Wallerawang Fire and Rescue NSW was alerted to the spill, which was believed to be caustic soda, as part of a general emergency response.

Deputy captain Luke Curran said patches of dead grass and puddles of chemicals were found in a dirt drain at the site. Absorbents were used to mop up the spill, which had pooled in the drain. It was then covered in sand.

‘Explosive’ Gas Level at Narooma Flat Pumping Station

About 100 people were evacuated from Narooma Easts Caravan Park after an ''explosive'' gas level was found in the sewer system. The Batemans Bay Fire and Rescue Hazmat were at the scene and a NSW Ambulance crew was on standby.

Eurobodalla Shire Council workers were doing a routine check of the pumping station at Narooma Flat when they detected an "explosive" gas level in the sewer system, a spokesman said.
"We have found fuel which has potentially been dumped in the sewer system, so we called triple-zero to get the Hazmat crews here and now it is in their hands," the spokesman said.

NSW Regulatory Update: New Safety requirement for Electric, Hybrid and Hydrogen Vehicles 

A new safety initiative has been introduced to help Emergency Services staff and first responders protect themselves and the public in the event of an incident. All electric, hybrid and hydrogen vehicles manufactured or modified after 1 January 2019 are now legally required to have a small identifying label fixed to the front and rear number plates. This includes light vehicles, and vehicles over 4.5 tonnes. 

The registered operators of all affected vehicles will soon receive a letter from Transport for NSW, along with the mandatory, self-adhesive labels and instructions on how to affix them to their vehicle. The labels will allow vehicles to be quickly identified as having an electric or hydrogen component, so that specific procedures can be followed in the event of a crash, to make it safer for all present. 

The new safety regulation came into effect on 1 September 2019 and fines may apply for failing to display the labels from 1 January 2020. The labels are required following an update to the Australian Light Vehicle Standards and Schedule 2 of the Road Transport (Vehicle Registration) Regulation 2017. Vehicles in NSW over 4.5 tonnes must also display the labels from 1 September 2019 under 108A and 108B of Schedule 2 of the Heavy Vehicle (Vehicle Standards) National Regulation (NSW).

Qld Resources Sector could get new Health and Safety Body 

Queensland’s resources sector could get a dedicated, independent health and safety body if a new Bill is successful. The Bill, introduced by Queensland Mines Minister Dr Anthony Lynham, 4 September, would see a newly formed statutory body take over the Department of Natural Resources, Mines and Energy’s health and safety functions — freeing the department to focus on growing mining and exploration projects and the resources sector as a whole.

Under the legislation, the proposed body, ‘Resources Safety and Health Queensland’, would absorb Queensland’s mines, explosives and petroleum and gas inspectors, the Redbank Safety in Mine Testing Station and the coalmine workers’ health scheme which covers mine dust lung diseases, such as black lung. It would report directly to the Minister, instead of through a department, and be subject to monitoring and review by an independent commissioner for mining and quarrying, petroleum and gas and explosives.

3 Parties fined in NSW Police/EPA Investigation 

A driver, transport company and recycling facility have been penalised by NSW authorities after a dangerous goods violation, while an adhesives company is also on notice, the state’s police force reports. NSW Police reports Hawkesbury Highway Patrol detected a Victorian-registered B-double travelling in an area it was not authorised to travel in Mulgrave (Windsor). "An inspection of the combination established it was carrying dangerous goods consisting of 24.4 tonnes of used lead acid batteries and 1,080 litres of flammable liquid adhesives," it continues.

"Issues were identified relevant to the vehicle and load, which were rectified before the vehicle could continue. "As a result of an investigation with the assistance of the NSW Environment Protection Authority, Police issued penalty notices to a number of parties involved in the transport of the dangerous goods." The Victorian-based transport company was penalised $10,000 for failing to ensure dangerous goods are transported safely. A Wollongong-based industrial recycling facility was issued a $4,000 penalty notice for the offence of ‘employ[ing] a person for task without appropriate supervision’.

Meanwhile, the driver of the heavy vehicle received about $2,000 worth of fines, including:
  • Drive without compliant emergency information holder - $260
  • Drive dangerous goods inappropriately placarded - $400
  • Drive class 2 heavy vehicle not in accordance with authorisation - $674
  • Not keep work diary as required - $674
NSW police also notes a Victorian-based adhesives company is also working with police and the EPA to implement changes to its dangerous goods procedures to ensure compliance. "NSW Police and the NSW Environment Protection Authority will continue to monitor the involved companies and take action where appropriate," it says.

Hazardous Chemicals dumped NSW South Coast

A two-day operation saw around 1000 litres of illegally-dumped hazardous waste safely removed from bush land, eight kilometres north west of Wyndham.

A concerned passer-by alerted Bega Valley Shire Council to the scene of five 200 litre gallon drums containing hazardous waste that were laying in a steep ravine at the foot of Mount Darragh.
NSW Fire and Rescue Eden spokesperson Zlatko Nemec said it was a lengthy operation including strategic planning and a large capacity crane being called in to carefully retrieve the potentially dangerous toxic waste, which lay out of reach from the Mount Darragh roadside.

"The safest way to remove the drums was to lift them out of the bush avoiding the risk of rupture," Mr Nemec said. Once retrieved the drums were transported under NSW Fire and Rescue escort to a Bega Valley Shire containment area. Bega Valley Shire Council confirmed the specific contents of the drums have not been conclusively determined and the matter is under investigation.

How the Law of Unintended Consequences complicates Occupational Health and Safety Compliance

The introduction of OHS-related legislation can sometimes lead to an overreaction on the part of some organisations, which inadvertently results in unnecessarily complex or rigid procedures – potentially increasing risks rather than decreasing them. If OHS-related legislation contains “scary” elements (such as industrial manslaughter), this is often an understandable flurry of activity to ensure that organisation are compliant and “protected” from the results of unforeseen events, said David Bentley, Leadership Specialist, Coach and Founder of consulting firm Just Leadership.

While the current model WHS laws are fairly “common sense friendly”, Bentley observed that there are more than a few historical examples of an overreaction to compliance fears and when the reaction is “too, well … reactive, it can result in a rush to introduce more complex or rigid procedures,” he said. “This common approach says that ‘if we restrict the actions of the workers by adding more steps, things won’t go wrong.’ “Unfortunately, this is where the ‘two-minute procedure that takes seven minutes to complete’ smacks head-on into the ‘real world’.” The unintended consequence is that complexity often increases risk rather than decreasing it, said Bentley, who recently spoke at the Tasmanian Safety Symposium & Trade Show 2019.

Former Executive of NSW Chemical Company to stand Trial 

When he was asked to pour large amounts of iodine from one container into another at the Sydney chemical company where he worked, Paul Flavell pushed back, worried about where it would end up. As a warehouse employee of Cyndan Chemicals, Mr Flavell knew the company never used iodine to make anything in its factory. He also knew the chemical was often used in the manufacture of drugs. “I asked ... why? It didn’t seem right, it didn’t seem lawful,” Mr Flavell told a Sydney court last week.

The former Cyndan Chemicals employee was one of multiple witnesses to appear at Central Local Court, where the company's former director Michael Snounou was committed to stand trial. Mr Snonou will stand trial for 32 offences, including importing hypophosphrous acid and gamma-butyrolactone (GBL) and possessing iodine, all suspected of being used in the manufacture of methylamphetamine, or ice. He is yet to enter a plea to any of the charges. Precursor chemicals can be legally imported in line with strict regulations however authorities are increasingly observing legitimate precursors being re-purposed to manufacture drugs like ice and ecstasy. Mr Snounou's arrest came four years after a lab explosion and fire at the Cyndan Chemicals factory premises in Warriewood in 2014.

The court heard the fire at the factory marked a change in operations for some members of staff. Mr Flavell gave evidence that iodine was among chemicals Cyndan "were not using in the factory to make anything," and that "after the fire it was my job" to repackage iodine into unmarked drums. When he asked why he was told "do your job, or else you won't get a job." Mr Flavell said this direction came from his immediate boss Caan Phillips, a current director of Chemlux Pty Ltd, trading as Cyndan Chemicals, and a witness during the committal hearing.

Chemical Drums dumped in Victorian Bush 

Drums of "extremely toxic" chemical waste have been dumped in bushland near a popular Melbourne walking track, requiring complex and lengthy clean-up operations. Authorities were first made aware of dumped chemicals and they found nine drums rolled down a gully just off Mount Dandenong Tourist Road near Upper Ferntree Gully. A Facebook post from the Upper Ferntree Gully CFA crew said it quickly became apparent when they found the drums that they were likely to contain "extremely toxic substances". "A large HAZMAT operation ensued which lasted nearly seven hours," they said. More drums were found at another two sites.

GHS or Dangerous Goods Label? 

AIDGC have identified that many people are confused about the difference between GHS and dangerous goods labels, where they do not understand when and where to place these labels.
ChemSafetyPro have published a 'Comparison of GHS and dangerous goods labels' article that offers a detailed comparison BUT MAY NOT APPLY IN AUSTRALIA 


AIDGC Consultant Richard Greenwood has recommended the 'GHS - What You need To Know' fact sheet from Safework NSW with the proviso that on page 5, the GHS environment pictogram is used twice instead of the TDG EHS marking. Richard also added that Placarding of Stores must use the relevant Dangerous Goods Label.

Dangerous Chemicals still remain in rubble of burnt Victorian Warehouse 

A massive stockpile of highly toxic chemicals has been discovered inside the rubble of a West Footscray warehouse more than a year after it burnt down during one of Melbourne’s worst industrial fires. Regulators are scrambling to contain the risk to public safety and potential environmental damage from up to 10 million litres of toxic waste contained in steel drums and other containers that survived the blaze in August 2018.

The EPA estimates there are 7 to 10 million litres of chemicals still inside the burnt-out and partially collapsed warehouse on Somerville Road, part of 7 to 15 million cubic metres of contaminated soil and building debris that must be remediated. However, the discovery - nearly 14 months after the fire - raises serious concerns about the EPA’s handling of the investigation and its decision to wait more than a year to conduct a survey of the site wreckage. The revelation that a sizeable stockpile of liquid chemicals were not incinerated in the blaze has led authorities to now post 24-hour guards at the property and revise emergency plans in the event contamination spreads to nearby properties and waterways.

The EPA’s failure to detect the massive supply of chemicals left behind after the West Footscray fire is the latest in a series of significant failings in investigating and stopping the syndicate behind the massive dumping operation. In 2016, the agency failed to investigate intelligence provided by Victoria Police that identified White was amassing chemicals in two factories in Epping. The EPA also belatedly discovered that one Campbellfield property controlled by White it had deemed as safe in early 2019 was later found to contain up to 1.6 million litres of chemicals hidden under bales of plastic. The revelation that a sizeable stockpile of liquid chemicals were not incinerated in the blaze has led authorities to now post 24-hour guards at the property and revise emergency plans in the event contamination spreads to nearby properties and waterways.

Another leak at Geelong Refinery

Emergency services have been called to Geelong’s oil refinery at least 12 times in 2019, again rushing to a leak at the Corio plant on October 14. The CFA was called to the Viva Refinery responding to a reported leak in a crude oil production line.

A spokesman for Viva Energy confirmed “Viva Energy can advise that the minor alarm has sounded at the Geelong Refinery due to a small leak,” the spokesman said. “As per procedure, the CFA are on site. Work is underway to isolate the leak”. The latest leak comes after an eventful year for the refinery, including explosions, raining chemicals and foul smelling odours wafting from the site.

In May, Viva Energy’s general manager Thys Heyns confirmed a “combustion event” temporarily shut down operations at the refinery — with a build-up of excess gas causing a metal pipe to combust.

In March, droplets of a “black grease-like” chemical showered nearby properties, with testing done by Viva Energy finding a chemical used to refine petrol had been released into the air from its flare stack.

In June a foul-smelling chemical odour wafted from the refinery, leaving nearby residents reporting dizziness, headaches and nausea. Viva Energy confirmed the strong stink came from the maintenance to sulphur recovery units at the plant.

Dodgy Operators Storing Dangerous Goods On Notice

Victorians are being asked to keep a look out for dodgy operators storing or handling dangerous goods in a way that might put the community at risk. An Andrews Labor Government awareness campaign has been launched urging members of the public to call WorkSafe if they suspect dangerous goods – such as drums or containers of flammable liquids – are being stored, handled or disposed of in a way which might be unsafe.

The campaign comes after legislation was introduced creating tough new penalties for the illegal storage and handling of dangerous goods, which could see individuals face up to 10 years in jail and body corporates fined more than $6.4 million for the most serious offences.

Members of the public are being asked to speak up if they see something that they think doesn’t look, sound or smell right. The six-week campaign features print, digital, radio, social media and outdoor advertising targeting high risk locations. The message will be translated into 10 different languages to raise awareness among the high number of migrant workers employed in the storage and handling of dangerous goods as they are particularly vulnerable to working in unsafe conditions.

Transport drivers and more than 25,000 workplaces associated with the storage and handling of dangerous goods are also targeted, to make sure they report unsafe practices and to increase their awareness of their obligations under the Dangerous Goods Act.

Chemical Fire at N.Z. Factory 

One person has been hospitalised and multiple people have been treated following a chemical-related fire at Fonterra's Whangarei factory. Fire and Emergency New Zealand (FENZ) spokesperson and shift manager Craig Dally said the fire was caused by an electric pump motor. Three fire crews initially responded to the incident, seven attending the scene in total. Dally said a small fire was extinguished before the arrival of Fire and Emergency crews. "Several unidentified chemicals were involved," he said. 

"The fire was possibly caused by an electric pump motor." Second Hazmat Incident at two different Fonterra Plants Firefighters attended a chlorine leak at Fonterra's Edendale plant in Southland, just eight-and-a-half hours after crew in Whangarei were called to a chemical spill and fire at a different Fonterra plant. Fire and Emergency New Zealand told 1 NEWS they were called to the Edendale incident just before 4am. Three fire crews wearing hazmat gear attended. Fonterra told 1 NEWS there was chlorine gas detected in a small shed.

New Zealand plans to phase out PFAS in Firefighting Foams 

New Zealand’s EPA is consulting on plans to phase out the use of perfluoroalkyl and polyfluoroalkyl substances (PFASs) in firefighting foam. The EPA considers that "these types of foams can be phased out as there are fluorine-free alternatives to PFAS firefighting foams now available that are already being used worldwide," it said.

Firefighting foams are regulated under New Zealand's Fire Fighting Chemicals Group Standard 2017. The proposed amendments are being treated as an application under the Hazardous Substances and New Organisms Act. They would phase out legacy fluorotelomer C8 aqueous film forming foams (AFFFs) as well as "modern" fluorotelomer C6 foams. The EPA proposes a raft of changes to the group standard.

The Importance of Chemical Storage Ventilation – U.K. White Paper 

Hazardous chemicals are an unavoidable part of day to day maintenance, manufacturing, cleaning, sterilisation, testing and operating applications. The storage of these chemicals involves a number of considerations. Find out what you need for the safe ventilation of corrosive chemicals. Many industries require a number of potentially hazardous chemicals in day to day maintenance, manufacturing, cleaning, sterilisation, testing and operating applications.

The safe storage of these chemicals involves a number of considerations in terms of temperature, ignition control, ventilation and segregation. The ventilation of chemical storage areas is of paramount importance to ensure clean air and a safe working factory environment. Ventilation is needed for chemicals and their containers as they have the potential to release dangerous quantities of vapours or gases that are damaging, flammable, corrosive, irritating or toxic. These vapours quickly accumulate and present a considerable hazard if left unventilated. Well ventilated storage is particularly key for those substances classed as fuming or highly volatile. It is recommended that such ventilation be by air extraction from the storage room or cupboard to an external exhaust at a safe distance from any openings (windows or doors) back into the building.

The fume extraction system needs to be suitable for handling air that is potentially corrosive, given the nature of the chemical vapours to be carried from the storage area. In such chemical fume extraction systems, it is best practice to site the fan at the end of the ductwork system. The reasoning behind this is to keep the ductwork under negative pressure which means, in the event of a leak, the system would draw in clean air rather than blowing out fumes into the building.

This would limit any damage caused by the leak before it was identified. In order to accurately specify a fan, there are two key pieces of information required; the airflow rate and the system resistance. Airflow rate is be based on the number of air changes per hour needed in the storage area. From the airflow rate, the size the ductwork is determined and so the system resistance is calculated. There may be a requirement to control the fan with a sensor to switch the fan on and off. This can be achieved with the use of an inverter. The sensor sends a signal to the inverter, which in turn controls the power source to the fan.

Crops harvesting banned after French Chemical Plant Fire

The huge blaze erupted in a storage facility owned by Lubrizol, a manufacturer of industrial lubricants and fuel additives. The soot spewed out by the blaze over some agricultural areas was “liable to present a public health risk that requires us to take immediate measures on a precautionary basis”, the regional administration said. It added in decrees published that in the absence of food safety guarantees from producers, anything likely to have been exposed to contamination would have to be destroyed. Around 100 districts in the area surrounding Rouen are expected to have been affected.
