The document describes an experiment to determine the surface tensions of surfactant solutions using a surface tensiometer. Sodium lauryl sulfate (SLS) was used as the surfactant. Surface tension measurements were taken of distilled water and varying concentrations of SLS solution from 0-2500 ppm. The results showed that the surface tension decreased with increasing concentration until reaching the critical micelle concentration around 2000 ppm, at which point it remained constant. The experimental data was compared to literature values and showed good agreement within 5% difference. Future work will test other surfactants not yet reported in literature.

A report by Safe Work Australia found that casual workers had injury rates 50% higher than permanent workers between 2009-2012. It also found that female workers had higher injury rates than males, and that rates were increasing for females while declining for males. The most common causes of injury across all groups were sprains and strains. Younger workers between 15-24 had the highest rates of injury compared to other age groups. The report recommends tailoring workplace safety training and procedures based on the risks for different demographic groups in order to reduce injuries.
Workers who renovate old buildings are at risk of inhaling asbestos fibers, which can cause deadly diseases like mesothelioma, pleural disease, and asbestosis. Australia has high rates of these diseases. Mesothelioma is a cancer affecting the lining of the lungs that develops 20-40 years after exposure and has poor survival rates. Pleural disease causes scarring and fluid buildup in the lungs. Asbestosis results in scarred, stiff lungs that have difficulty absorbing oxygen.
WorkSafe will focus return to work inspections on the Dandenong area in Victoria this month. Over the past 5 years, the region has reported approximately 8,360 injuries costing $197 million. Inspectors will visit employers to ensure they are meeting return to work obligations for injured employees and providing guidance. Employers are encouraged to attend a free workshop on returning injured workers to their jobs successfully and lowering insurance costs.
Heavy construction equipment causes approximately 100 worker deaths per year due to various accidents. Workers are often struck when equipment changes direction or reverses, or are crushed by equipment rollovers or falling objects. To prevent injuries, workers must follow all safety guidelines and operate equipment with caution, maintaining visibility and reducing speeds, especially near pedestrians.
Three steps are outlined to manage fall hazards: 1) Distribute responsibilities among workers for fall prevention, equipment use, safety maintenance, and training. 2) Identify all tasks with potential falls over two meters such as construction and roof work. 3) Assess risks and situations considering workplace layout, work duration and height, employee training, and access to work areas. If risk can't be eliminated, precautions must be taken.
Scaffolding poses serious dangers to construction workers such as falls, being struck by falling objects, electrical shock, and scaffold failure. Safety measures like harnesses, guardrails, hard hats, and fall arrest systems can help reduce risks but should not replace proper scaffold setup and maintenance to prevent injuries and deaths from scaffolding accidents.
Numerous deaths occur each year from falls from scaffolding during construction. Even falls from low heights can be serious or fatal. Scaffolding is necessary for construction but presents fall risks that workers must be trained to manage properly. Safe work practices like progressive scaffold erection, installing guardrails and fall arrest systems, and using harnesses and other PPE can help prevent falls when working with scaffolding. Proper planning, supervision, and safety protocols are essential to reducing risks.
Trench and excavation safety is important to train construction workers on to prevent tragedy. Employers and employees should identify hazards associated with trench and excavation work before, during, and after work to assess and minimize risks, particularly the risk of collapse from instability. Workers should review if work in a trench or excavation is necessary and consider safer alternatives. If work must be done, proper permissions, PPE provided by the employer with training on use, and engineering controls to separate other workers from hazards are required to maintain safety.
Welding is a common but hazardous construction activity that can cause burns, electric shock, radiation exposure, and fires or explosions if not done safely. The risks are increased when welding in confined spaces due to dangers from fumes, gases, and heat that can damage organs or cause illness. Proper ventilation, personal protective equipment like clothing, eye protection and masks, and fire safety measures can minimize these risks, but controlling hazards is vital for welder safety.
Welding is a hazardous activity commonly used in construction that can cause injuries like burns, electric shock, and radiation exposure. When welding in confined spaces, there are additional risks such as metal fume fever from toxic fumes, welders' flash from ultraviolet light, and poisonous gas formation if welding near solvents. Proper safety precautions like ventilation, protective equipment, and fire extinguishers can minimize these risks.
Attention Construction Workers: Learn what to do in the Event of a Firewhitecardaustralia0
This document provides guidelines for construction workers in the event of a fire. It advises that the top priority is personal safety - workers should remove themselves from danger and not attempt to rescue others if it puts their own life at risk. Once safe, workers should try to isolate the fire if possible and call emergency services. All workers should gather at the designated meeting point so they can be accounted for.
OHS Update: The Importance of Hand Protection in Construction Safetywhitecardaustralia0
Construction workers' hands are susceptible to many hazards that can cause permanent damage due to their reliance on their hands for their livelihood. Once risks are assessed and identified, appropriate safety measures like personal protective equipment should be designed and implemented, including the use of gloves to prevent or lessen injury from physical hazards like sharp edges, vibration, heat, corrosive chemicals as identified by materials safety data sheets, and ultraviolet radiation which can cause skin diseases.
Workers who engage in renovation and construction are at risk of inhaling asbestos fibers from old building materials, which can lead to deadly diseases like mesothelioma, pleural disease, and asbestosis. Mesothelioma is a cancer of the lining of the lungs that occurs 20-40 years after exposure and has a very short survival time after diagnosis. Pleural disease causes scarring and fluid buildup in the lining of the lungs, restricting breathing. Asbestosis results in scarred, stiff lungs that cannot take in enough oxygen. Australia has high rates of these asbestos-related diseases.
Workers who engage in renovation and construction are at risk of inhaling asbestos fibers, which can lead to deadly diseases like mesothelioma, pleural disease, and asbestosis. Mesothelioma is a cancer of the lining of the lungs that typically occurs 20-40 years after exposure and has a very poor prognosis. Pleural disease causes scarring and thickening of the lining of the lungs, restricting breathing. Asbestosis results in scarring of the lungs themselves, making breathing difficult. Australia has high rates of these asbestos-related diseases.
WorkSafe Victoria issued an alert warning that November and December are the deadliest months for workplace deaths, with 7 workers dying in 12 days and 9 deaths in 24 days the previous year. Statistics over the past 5 years show this period has extremely high workplace fatality rates. While the exact cause is unclear, WorkSafe speculates safety practices may lapse as companies rush to finish jobs before the summer break and holidays. Most past incidents occurred during routine tasks, suggesting workers' attitudes or approaches change in a way that compromises safety.

Scaffolding is vital for construction but also dangerous, as falls are a leading cause of death in the industry. Proper planning, supervision, training, and fall protection equipment can help reduce risks when erecting or dismantling scaffolding. Scaffolds should be built sequentially with railings and safe access between levels to prevent falls, and safety harnesses alone are not sufficient—they must be properly anchored.
Construction workers face serious safety risks when working with scaffolding, including falls, being struck by falling objects, and scaffold or component failure. Proper safety equipment like harnesses and hard hats, guardrails, screens, and fall arrest systems can help reduce risks but should not replace following safe scaffolding setup and dismantling practices. Workers must take precautions to safely assemble, use, and take down scaffolding.
Distribute responsibilities to identify and assess fall hazards. Workers must be trained to comply with regulations to prevent falls over two meters, for tasks like construction and maintenance. Employers should consider workplace conditions, work duration and height, training, and how workers access areas to manage risks where eliminating them is not possible.

How to combat bullying in on the construction site

Bullying in the construction industry
Workplace bullying is a problem that has been plaguing a number of worksites and schools in
Oz. There are no industries that are immune to workplace bullying, even the construction
industry has workers who complain of this unacceptable behaviour directed towards them. This
incident was highlighted by a victim on the Bullyonline.org website anddescribes an example of
workplace bullying masked under the guise of management. The worker was treated differently
from others and discriminated against.
This is what the post had to say:
After a couple of weeks of starting we were
in the Architect’s office, which was full of their staff listening to the discussion, when I
pulled the PM aside making a few suggestions how to go forward on an issue. This lead
to a tirade of abuse from him, who seemed to be holding me liable for all the mistakes
on the job, even those prior to my arrival. This left me devastated and I then had to sit in
a meeting with the PM until 8pm that night when all I wanted to do was get away from
him.
The following morning I arrived at work at 7am when it started again, an absolute tirade
of abuse and being blamed for all sorts. Things went from bad to worse, although he
didn’t verbally abuse me (he did others but they just got on with it) but it upset me
greatly to think his behaviour was not corrected by his (the PM’s) boss.
I was meant to be in charge of a department but my ideas of what my priorities were
never coincided with that of the PM, who had me continually updating his schedules.
When I complained to my manager in head office I was told not to worry just keep the
PM happy.
Other staff went on courses, including staff from my own department, but I wasn’t
allowed to. I found out that mine had been cancelled by the PM and the few I did get
manage to get on I would receive a call at the training centre telling me to get back to

This illustrates just one type of bullying that occurs daily in workplaces, bullying of staff by
superiors. It is as equally unacceptable as any other type of bullying. Bullying can be in the
form of verbal, physical, social or psychological abuse. Like in the post above it can be from
your employer, supervisor, another person or group of people at work and occurs in all types of
workplaces and industries.
Many of the workplace woes we see as a result of bullying include reduced productivity,
increased absenteeism, physical stress such as headaches, backaches, insomnia. These side
effects ultimately affect a person’s ability to do their job and so employers should take these
incidents more seriously. It is important that workers feel that their complaints will be taken
seriously, unlike in the case above. Superiors should not be given absolute power to make
employees lives miserable so accusations of victimisation should be taken seriously regardless
of their rank or position.
Some of the most common examples of workplace bullying include making repeated hurtful
remarks, sexual harassment, playing mind games, shoving, pushing, tripping or any uninvited
and harmful physical contact, intimidation, threatening and ganging up on a worker.
Employers are allowed to transfer you, demote, discipline, counsel, retrench or fire you for valid
reasons. However if it is preceded by intimidating or bullying behaviour then it is unacceptable.
Workers who are being bullied often suffer from severe depression, which has led to suicide in
the past. But there is recourse that workers can follow.
Most workplaces should have workplace bullying policy and complaints procedures in place and
if they do, workers should follow it. However if not, workers should contact their immediate
supervisor. If the supervisor is the cause of the bullying, speak to someone above him/her. If
your company is not doing anything and the bullying continues, you can approach your union,
discuss the situation and seek advice from them.
Also ensure that all your complaints are written down and you keep a track record of all the
cases of bullying, when and where they occurred.
You can talk to your supervisor/manager, a harassment contact officer, or a health and safety
representative. It is important that workers are aware of the help available to them so that they
do not feel hopeless and depressed which can lead to tragic consequences such as suicide.
