Health AND Safety

Workplace health and safety. Occupational health and safety. Or in the current legislative framework,  work health and safety.

So many people think of physical risks when it comes to health and safety at work . Slips,  trips and falls.  But the elements of health and safety that are seen in the public eye are about health.

Silicosis? Health.  Asbestosis, mesothelioma. Health.  Lead poisoning.  Health.

Too often, mental health is only considered as a secondary injury. This is typically when an injured worker has been off work for several week. They may develop a secondary condition, such as depression as a side effect of their injury.

Bullying and harassment can cause mental injury. It is one of many psychosocial risks present in a workplace. Violence, whether from colleagues or members of the public. Employers have obligations about all risks to health safety, physical and mental.

Psychosocial risks, those risks to mental health can include such things as:

  • Job demands that are too high or too low – unreasonably busy and exceeding an employee’s capacity, or monotonous work.
  • Low job control – micromanaging, not allowing employees any input, or little input, into how the work is done, or scheduled, and little input into objectives and targets.
  • Poor support – no or inadequate training and supervision, day to day support and leadership, inadequate tools, resources and information to do the job.
  • Low role clarity – frequently changing work assignments and procedures, conflicts in scheduling and expectations.
  • Poor organisational change management – where change is poorly planned, communicated, managed or supported.
  • Low reward and recognition – where the employee may perceive an imbalance in effort vs recognition, either formally or informally.
  • Poor organisational justice – little or no transparency about how are issues are managed, investigated and communicatdd, and little consideration for dignity or respect.
  • Poor workplace relationships and conflict – from rudeness to disagreements and to ostracism and exclusion.
  • Remote or isolated work – this could be location, time or nature of the work, such as night shift workers or surveyors on remote sites.
  • Poor environmental conditions – when workplace conditions are unpleasant, in poor condition, physically hazardous, of hazardous nature, and could trigger a stress response.
  • Traumatic events – experiencing, investigating, reading, witnessing or hearing about, for example, armed robberies, assaults, fatal vehicle accidents. This could also include intentional cruelty.
  • Violence and aggression- where an employee could be abused, threatened or assaulted, and could be instigated by co-workers, customers, patients, clients or visitors.
  • Bullying
  • Harassment, including sexual harassment.
  • Fatigue.

The “Managing the risk of psychosocial hazards at work Code of Practice 2022” is the “gold standard” guide on how to prevent harm from psychosocial risks.

So how might that look?

Imagine that you manage a team of accountants at head office. One of those accountants is newly diagnosed, and requests supports and accommodations. Refusing those supports and accommodations, other team members making disparaging remarks, and the person suddenly being excluded from team lunches or outings, and a reduction in workload complexity without consultation could well cause psychosocial harm to that team member.

Or, say you have an internal auditor visiting a branch office. No desk space has been provided,  documents are not available and the auditor’s requests are ignored. The auditor is then threatened about making a complaint.

Or, say a female worker has just had a miscarriage, and she is ordered to work from home when she is ready to come back to work, because management don’t want her grief upsetting morale at the office. She then hears a snide remark about “keeping her legs closed” after a Teams meeting was not quite disconnected.

Why care about these things? Because the law says so. Persons in control of a business or undertaking (PCBUs) directors, designers of structures, officers and individuals all have obligations under health and safety legislation.

So once again, the call is to be kind, fair, transparent, and act with integrity. Know your obligations under law as an employer, and comply with obligations under the Work Health and Safety Act 2011 (Qld) or the relevant legislation in your jurisdiction.

Occupational health and safety – a blast from the past

Some people hear the words “health and safety”, roll their eyes and mutter about “fun police”.

In my 22 years in occupational health and safety, that was never my intent. But from call centre workers to fuel truck drivers, each role does hold inherent risks, and those risks need to managed. That is what occupational health and safety is – minimising the risk of harm for workers.

Something else from the past is driveway service at the servo (that’s Australian for service station, or gas station).

At one point in my career, I had to do a risk assessment for benzene exposure for a service station that still did driveway service.

Names have been changed or blanked to protect the innocent (or, not so innocent).


Health Surveillance – Exposure to benzene from driveway service


Executive Summary
This report looks at the need for health surveillance associated with exposure to benzene in fuel vapours while providing driveway service at unnamed service station. Driveway service was, in 2011, considered a unique selling point to drive sales at this outlet.
Based on mean and exposure levels quoted in the 1997 National Environmental Health Monograph on benzene, and average sales through this outlet, health surveillance was not required for unnamed service station.


Health hazards associated with benzene
Benzene, a constituent of unleaded petrol, is a Category 1 carcinogen, and by law is restricted to less than 1% by volume per litre of unleaded petrol. The primary route of exposure for the generalpopulation, including staff at retail fuel outlets, is via inhalation of vapours while refuelling cars, in exhaust and in cigarette smoke. This risk assessment looks exclusively at exposure from vapours while carrying out driveway service at unnamed service station.


Health effects
(From MSDS provided by supplier Mobil Exxon.)
ACUTE: Inhalation of this product’s vapours can cause headaches, nausea, dizziness, and drowsiness.
Severe inhalation overexposures may be fatal, due to asphyxiation.
CHRONIC: Chronic exposure to Benzene causes serious damage to the health by all routes of exposure. Chronic oral and inhalation exposure causes severe effects on the blood system (e.g. damage to the bone marrow). Effects can occur with an exposure level as low as 10 ppm for 24
weeks. Benzene also causes harmful changes to the immune system, decreasing the production of mature B- and T- white blood cells. Benzene is a confirmed human carcinogen, which can produce Hodgkin’s Disease, leukaemia and lymphomas by inhalation. Benzene is a potential reproductive toxin.


Existing data
There is no data currently available for atmospheric monitoring at unnamed service station.


Data has been obtained from the National Environmental Health Monograph for benzene, which quotes a 1993 study where benzene concentrations in air were measured in 83 samples from 11 service stations in major cities across Australia. 8-hour average samples were collected next to pumps. The mean concentration for these samples was 107 ppb (range 20 – 600 ppb). The monograph concluded that individuals will therefore be exposed briefly to relatively high concentrations of benzene.

Evaluating the potential exposure of employees
Australian fuel standards require that motor spirit contains no more benzene than 1% by volume.


Unnamed service station sells an average of 22,000 litres of unleaded petrol each week, and is a low volume site, with an average of 6 sales per hour and an average of 31 litres per sale.


The monograph for benzene produced by the National Environmental Health Forum in 1997 quotes a study carried out in 1993, where benzene concentration in air were measured in 83 samples from 11 service stations in major cities across Australia, with 8-hour average samples collected adjacent to pumps. This showed the mean concentration for these samples to be 107 ppb (range 20-600 ppb). Ppb means parts per billion.


The exposure limit, TWA is 1ppm. Converting the maximum measurement in the range of 600ppb to
0.6ppm, an employee conducting driveway service will receive less than the allowable exposure limit
during their occupational exposure.


Atmospheric monitoring
It is not industry practice to conduct atmospheric monitoring for the presence of benzene and other chemicals in the air around pumps and bowsers unless it is required by local authorities to support Development Applications of the retail site itself or neighbouring developments.
Environmental health initiatives to reduce public exposure to VOCs (volatile organic compounds) have seen the introduction of Stage 1 Vapour Recovery to manage vapours during the bulk loading process. Stage 1 Vapour Recovery is in place at this site. Stage 2 Vapour Recovery, to capture vapours during car refuelling, had not yet been implemented in 2011, but is in new service stations in 2024. The introduction of Stage 2 vapour recovery is estimated to reduce vapours in the atmosphere by approximately 95%.


Health surveillance
Health surveillance is mandated for petroleum industry workers, where atmospheric contamination is an ever-present hazard. Health surveillance is not mandated for retail fuel outlet workers.


Health Watch, the pre-eminent health surveillance study for the petroleum industry in Australia, specifically excludes retail service station workers as exposure at retail worksites is generally similar to that of the general community, i.e. the occupational exposure is very low. Employees who smoke are exposed to benzene in cigarette smoke at far greater rates than is possible through vapours from fuelling a vehicle.

Recommendation
Health surveillance is not required for our employees who provide driveway service at unnamed service station.
