The Respirator fit testing is a necessary procedure to make sure that the respiratory protection is working as intended. Even the best respirator will not protect appropriately when it is not fitted correctly. Fit testing requires some proper preparation to not only get the right results but also to comply the workplace health and safety […]
Indoor Air Quality (IAQ) plays a crucial role in the health, comfort, and productivity of building occupants. Poor indoor air quality can contribute to a wide range of issues, including respiratory problems, allergies, headaches, fatigue, and long-term health risks. Whether in a home, office, school, or commercial facility, IAQ testing helps identify hidden pollutants and […]
Important Definitions for Understanding Mould Reports Understanding mould reports requires familiarity with several key definitions and concepts. This section provides clear explanations of the different conditions of mould growth, as well as the term “environmental mould growth”, to assist readers in interpreting assessment and restoration documents. Condition 1 Mould Growth Condition 1 mould growth, as […]
Testing for fire smoke and soot damage is an essential step after any fire event in a property. While some damage is easy to see, tiny particles and toxic chemicals can linger unseen, settling deep within HVAC systems, wall cavities, and porous materials. These hidden contaminants can pose lasting health and safety risks long after […]
The Growing Importance of Clandestine Drug Testing The increase in illicit drug manufacturing, especially methamphetamine, has made clandestine drug testing an essential focus for property owners, tenants, and local authorities. So-called “clan labs” are makeshift setups for producing illegal drugs and often leave behind hazardous chemical residues. The IOHC occupational hygiene team specialises in testing […]
Mould is more than just an unpleasant stain on a bathroom wall—it’s a warning sign of a much bigger problem. Hidden moisture, structural issues, and poor indoor air quality often lie beneath the surface of what we can see. And while some mould is obvious, much of it grows silently behind walls, under floors, inside […]
Many workers are exposed to various hazards, including dust, fumes, fibres, chemicals, vapours, gases, biological hazards, and noise, during their daily work activities. The risks posed by those hazards depend on the severity of the hazards and how much time the worker is exposed to the hazard. Occupational hygienists specialise in carrying out risk assessments […]
An Indoor Air Quality (IAQ) survey is a comprehensive assessment used to evaluate the air quality within indoor environments such as homes and offices. These surveys are often mistaken for industrial occupational hygiene assessments, which focus on evaluating exposure to hazards like welding fumes, chemicals, and other airborne contaminants in industrial settings. At IOHC, we […]
What does a respirator fit test consist of? Respirator fit testing includes training participants on the proper use and maintenance of respirators, as well as conducting fit checks to ensure the respirator fits correctly, and finally, quantitative respirator fit testing to verify that the respirator provides adequate protection. It is common for the tester to […]
Why is there mould in my house? The most common question we face is why there is mould in my house. We call those mould assessments a causation survey, which aims to identify root causes contributing to mould growth in the property. Mould can be caused by one of the following four reasons or a […]
When are Audiometry assessments required? Audiometry assessments are required for workers in high-noise environments where their exposure exceeds the workplace exposure standards. Workplaces should carry out noise surveys of the areas to estimate the workers’ exposure and use the outcome of the assessment to identify at-risk employees. The results of the noise surveys and risk […]
Yes, we have moved to a new location and here is information on how to find us. IOHC respirator fit testing is now located at 17/2962 Logan Road, Underwood. We are located in the Underwood, which is approximately 15- 20 minutes (approximately 20 km) from Brisbane.
There is no single answer to this question. The answer depends on what you need protection against. The respirator must be selected based on several factors, including the operator’s comfort, contaminants, required protection factor, task factors, and compliance with PPE.
Our trained fit testing operators ensure that each participant receives training in the proper wearing, maintenance, and disposal of respirators, which is also a requirement under the respiratory protection program.
Noise area surveys are carried out to determine the noise levels in different areas of the workplace. The class 1 integrating sound level meter is usually used to measure…
Occupational hygienists recommend the type of air monitoring depending on the workplace, dust exposures and the purpose of the assessment. There are three main types of air monitoring used for silica dust exposure assessments.
The fit test is a test to ensure that the selected respirator can adequately seal around the wearer’s face and provide the required level of protection. Respirator fit testing also includes providing workers with training…
A new code of practice on silica exposure in construction came into effect on 1st May 2023, all workers working in the construction industry where they can be exposed to respirable crystalline silica need to be fit-tested…
