Hazardous Chemicals are dangerous to humans, property, and the environment, and are commonly used across many industries (and workplaces) in Australia. We work with clients to assure safety, education, and strict management practices are carried out and maintained when dealing with hazardous elements. Chemicals enter the body principally through inhalation, skin absorption or ingestion. The toxic effect caused by exposure to hazardous chemicals may be acute, chronic or both. To start off, we’ve outlined a standard Hazchem Risk Management Process to provide a better idea of what to look out for if your employees handle chemicals on a regular basis.

A list of reactions and health effects as caused by hazardous chemicals can be attributed to a number of causes:

  • Corrosive chemicals (such as acids, and alkalis) cause destruction at the site of contact. Skin, eyes, and digestive systems are the most commonly affected parts of the body.
  • Irritants (chlorine) cause inflammation of tissues where they are deposited. Skin irritants may cause reactions like eczema or dermatitis. Severe respiratory irritants may cause shortness of breath, inflammatory responses, and oedema.
  • Allergic reactions (metals, oils) can be created by chemical allergens or sensitisers which cause skin or respiratory allergic reactions.
  • Asphyxiants (CO, H2S) exert their effects by interfering with the oxygenation of the tissues. Simple asphyxiants are inert gases that dilute the available atmospheric oxygen below the level required to support life. Oxygen-deficient atmospheres may occur in tanks, holds of ships, silos or mines. The oxygen concentration in the air should never be below 19.5% by volume.
  • Human carcinogens (benzene, vinyl chloride) are chemicals that have been clearly demonstrated to cause cancer in humans. Soot and coal tars were the first chemicals suspected to cause cancer.
  • Reproductive effects (manganese, mercury, lead) interfere with the reproductive or sexual functioning of an individual. Developmental toxicants are agents that may cause an adverse effect on offspring (such as birth defects) of exposed persons. Embryotoxic or foetotoxic chemicals can cause spontaneous abortions or miscarriages.
  • Systemic poisons (lead, mercury, cadmium) are agents that injure particular organs or body systems which cause long-term chronic illness.

Can you spot potential hazards lurking in the images below?

  GCG work with clients to promote practices in order to eliminate all forms of hazardous exposure to chemicals and maintain systems to ensure all practices are undertaken according to regulations and legislation outlined in the Dangerous Goods Standard and the NOHSC model. Adhering to the WHS system of chemical classification, and hazard communication on labels and Safety Data Sheets (SDS), we believe our clients have the ability to successfully control the well-being of their people who deal with hazardous chemicals in the workplace.

The real-time dust monitoring driving change

Real-time dust monitoring has really come into its own in the last few years. The ubiquity of real-time monitoring devices and the recent emergence of intelligent dust exposure control applications and platforms like GCG’s ‘Exposi’ system have taken monitoring and management of dust exposure to a new level. Hygienists and safety professionals now have the ability to make smarter, faster decisions around dust control management. Real-time hardware devices capture data…

The rise of fixed point real-time dust monitoring 

Increased awareness of silicosis and other occupational lung diseases caused by exposure to hazardous levels of respirable crystalline silica has prompted employers and workers to seek ways to reduce the potential for worker exposure to hazardous dust. This has driven a rise in the uptake of dust monitoring technologies including Remote Real-time Dust Monitoring (Fixed Point Monitoring) in workplaces across Australia. In Australia, silicosis has been known to cause…

How can a work health and safety management system help my business?

A work health safety management system (WHSMS) A WHSMS is a systems-based approach to help companies manage their work health and safety risks and maintain compliance with current legislative requirements. What is a work health and safety management system? A WHSMS is a collective set of procedures, plans, and associated documents that align with business operations and support the process of managing workplace health and safety.

Is your WA principal mining hazard management plan up to date?

The terms and definitions used in reference to ‘principal mining hazards’ vary across Australia. In Western Australia new Work Health and Safety (WHS) laws and accompanying regulations came into effect on 31 March 2022, introducing a meaning for, and a list of, principal mining hazards (PMHs). While it’s likely your risk management framework already identifies principal mining hazards, they may not be addressed as comprehensively as…

What’s next on the journey to eliminate silicosis?

The re-emergence of occupational lung diseases across Australia, such as silicosis and coal worker pneumoconiosis, has received significant focus from industry, regulators, and unions alike. Since 2016, a series of government reviews, task forces, and parliamentary inquiries have identified gaps in hazard awareness, compliance, and regulatory frameworks relating to airborne dust. These documents also identify that preventing occupational lung disease is a complex problem to solve. Occupational…
