OHS Health and Wellness in the Workplace: A Complete Guide

Let’s talk about lighting requirements in the workplace.
Proper workplace lighting is essential for safety and productivity, requiring adequate, consistent illumination to prevent accidents, eye strain, and fatigue. Key requirements include minimizing glare and shadows, ensuring appropriate standard units for measuring lighting levels, and conducting regular assessments to maintain safe environments.

Now consider this: poor lighting makes people cranky. Lighting influences mood, stress levels, attention span, and even interpersonal interactions. In one study, poorly lit environments correlated with higher reports of depression, eye strain, and absenteeism.

I’d like to turn your attention to compliance and care. From a compliance and care perspective, lighting is part of the Occupational Health and Safety, specifically addressed under the Environmental Regulations for Workplaces. Poor lighting is a hazard, not just an inconvenience.

Let’s examine the evidence. According to research cited by the International Labour Organization, workplaces with inadequate lighting have higher incidents of accidents, eye strain, headaches, and errors.

One of the most immediate benefits of good workplace lighting is improved safety. In environments like manufacturing plants, construction sites, and warehouses, where physical tasks are the norm, clear visibility is essential. Poorly lit areas can hide hazards like spills, uneven flooring, or moving machinery.

Thermal conditions in the workplace, including extreme heat and cold, pose significant health risks if not properly managed.

Heat-related illnesses such as heat exhaustion and heat stroke can occur, while exposure to cold can lead to hypothermia and frostbite.

Employers must address these risks through thorough assessments, providing rest breaks, ensuring access to suitable clothing, and promoting adequate hydration.

Working in extreme temperatures, whether hot or cold, can overwhelm the body’s internal temperature regulation system.

When the body is unable to cool or warm itself effectively, heat or cold stress may develop. Both conditions can lead to adverse health effects, ranging from mild discomfort to death.

Heat stress is typically caused by a combination of air temperature, radiant heat, airflow, and humidity. Controlling any one of these factors can reduce heat stress. Failure to monitor these conditions properly may expose employees to:

• Dehydration

• Heat stroke

• Fainting

• Poor concentration and fatigue

The quality of the air we breathe plays a crucial role in our overall health and well-being. Indoor and workplace air quality can be influenced by a range of factors.
Measurements are taken to assess workplace air quality and to determine whether any measures are necessary to meet occupational exposure limits.

Workplace environments, whether production facilities or office spaces, may be adversely affected by air pollution originating from manufacturing processes or nearby external sources. Such pollution can impact employees’ health, productivity, and job satisfaction.

Under Regulation of the Workplace, Health, Safety and Welfare, employers are required to ensure that every enclosed workplace is ventilated by a sufficient quantity of fresh or purified air.

Improving indoor air quality is essential for protecting employee health and reducing respiratory issues, fatigue, and headaches. Key strategies include upgrading Heating, Ventilation, and Air Conditioning systems, increasing ventilation, and installing air purification systems.

Let's begin by examining a critical, yet often overlooked, workplace health hazard, noise and vibration.

Excessive workplace noise and vibration can have serious and permanent health consequences. Prolonged exposure to noise above permissible limits can result in irreversible hearing loss, while exposure to vibration from power tools and machinery can damage nerves, blood vessels, muscles, and joints, leading to conditions such as Hand-Arm Vibration Syndrome.

Employers are responsible for assessing these risks, implementing appropriate control measures, and conducting regular exposure monitoring.

Workplace radiation includes ionizing which is X-rays and nuclear, and non-ionizing which is Ultraviolet and lasers sources. These pose risks like cancer or tissue damage if unregulated. Key industries include healthcare, mining, nuclear power and petrochemical in pipe welding certification. Radiation Safety requires minimizing exposure via time spent in radiation environment, distance from radioactive source, and shielding protection against harmful rays.

Notifiable substances are hazardous substances that employers and users of machinery must report to the relevant authorities if they are in possession of a quantity that exceeds a certain threshold.

Why is there a need to report them to the Chief Inspector of Factories?

Under the Occupational Health and Safety Act, certain substances must be reported to the authorities if they are used, stored, or handled in a workplace. These substances, known as notifiable substances, are outlined in the General Machinery Regulations and other relevant regulations. The notification process ensures that potentially hazardous substances are properly monitored and controlled.

The requirement for reporting notifiable substances under the Occupational Health and Safety Act is to safeguard the health and safety of workers and the public. By mandating the reporting of hazardous substances in the workplace, the Act enables proactive measures to manage risks and prevent potential harm.

Occupational hazardous materials include toxic chemicals, dusts, heavy metals, and gases that enter the body through inhalation, ingestion, or skin absorption.

Common workplace hazards like asbestos, lead, benzene, and silica cause severe short-term irritation and long-term chronic illnesses such as lung disease, organ failure, and cancer.

Many occupational hazards can cause occupational diseases that develop over months or years.

Let's look at some of these in more detail.

Lifting heavy items is one of the leading causes of workplace injuries. According to the Bureau of Labor Statistics, over 36% of injuries involving missed workdays resulted from shoulder and back injuries. Manual handling strain is a major contributing factor to these injuries. Bending, followed by twisting and turning, are the most commonly cited movements leading to back injuries.

When employees use smart lifting practices, they are less likely to suffer from back sprains, muscle pulls, and wrist injuries.

Employers have a legal and moral responsibility to protect the health, safety, dignity, and rights of all employees.

However, viruses such as COVID-19 require very different workplace management approaches.

Managing viruses and Other Respiratory Viruses.

Unlike HIV, which is a blood-borne virus, viruses and other respiratory viruses such as influenza spread primarily through respiratory droplets and tiny airborne particles released when infected individuals cough, sneeze, speak, sing, or even breathe.

These viruses can spread rapidly in workplaces where employees work in close proximity or share enclosed spaces.

Employers therefore have a responsibility to reduce the risk of transmission by implementing effective infection prevention and control measures that protect employees, contractors, visitors, and customers.

Employers have a legal and moral responsibility to protect the health, safety, dignity, and rights of all employees.

However, Human Immunodeficiency Virus (HIV) require very different workplace management approaches because spread in different ways.

Managing Employees Living with HIV.

Managing HIV in the workplace is not about isolating employees living with HIV, but about creating a safe, respectful, and inclusive work environment.

Since HIV is not spread through normal workplace contact, employers should protect the rights and dignity of employees living with HIV.

Standard safety precautions should be applied whenever there is a possibility of exposure to blood or other potentially infectious body fluids.

Occupational Disease. The Silent Threat.

An occupational disease is any disease caused primarily by exposure at work to chemical or biological risk factor. The recognition of an occupational disease may be linked to compensation.

Illness caused by exposure to hazards in the work environment can have devastating long-term consequences.

‍What is Occupational Illness?

Common Types of Occupational Illness.

Here are some of the most common categories.

‍Respiratory Diseases‍.

Exposure to dusts, fumes, gases, and vapours can lead to conditions like occupational asthma, and lung cancer.

Skin Diseases.

Contact with irritants or allergens can cause various skin problems, including dermatitis, eczema, and skin cancer.

‍

Cancer.

Exposure to asbestos, arsenic, benzene, and radon, among others, can increase the risk of various cancers.

‍

Cardiovascular Diseases.

Exposure to carbon monoxide, lead, and some organic solvents has been linked to increased risk of heart disease.

‍

Musculoskeletal Disorders.

These disorders affect muscles, tendons, ligaments, and nerves.

‍

Hearing Loss.

Prolonged exposure to loud noise and specific chemicals can cause irreversible hearing damage.

Mental health and psychosocial wellbeing have become critical workplace priorities because of their direct impact on employee performance, safety, engagement, and productivity. It is estimated that approximately 15% of working-age adults are living with a mental health disorder, highlighting the significant challenge faced by employers worldwide.

So, what do we mean by psychosocial wellbeing?

Psychosocial wellbeing refers to an employee's overall psychological, emotional, social, and mental state in the workplace. It reflects how people experience their work environment, interact with colleagues, manage workplace demands, and maintain a healthy work-life balance.

Factors such as excessive workloads, limited job control, poor supervisory support, workplace harassment, and job insecurity can significantly increase psychological risks and negatively affect employees' wellbeing.

Every employee has the right to a safe and healthy working environment where both physical and mental health are protected, supported, and promoted.

Incapacity refers to an employee's inability to perform their duties to the required standard due to factors beyond their control.

These factors typically include poor work performance, ill health, injury, unsuitability, or incompatibility.

It is important to distinguish incapacity from misconduct.

Misconduct involves intentional wrongdoing or negligence, whereas incapacity arises because an employee lacks the ability, competence, or physical or mental capacity to perform the job.

From an Occupational Health and Safety perspective, incapacity is often linked to workplace hazards, occupational exposures, and working conditions that affect an employee's health and ability to work safely.

What Are Periodic and Annual Medical Examinations?

Periodic and annual medical examinations are scheduled health assessments for employees working in safety-sensitive or regulated roles. They help confirm that workers remain medically fit to perform their duties safely over time.

The frequency and scope of these examinations are determined by the employee's job requirements and occupational risks.

Under occupational health and safety legislation, periodic and annual medical examinations are a legal requirement where workplace risk assessments identify employee exposure to specific health hazards, such as excessive noise, dust, lead, asbestos, or hazardous chemical substances.

Lockout and Tagout is a safety procedure requiring that machines be fully shut down, isolated from all energy sources, and physically locked before maintenance or servicing begins. It covers electrical, hydraulic, pneumatic, thermal, gravitational, and stored energy.

Lockout and Tagout failures typically occur when procedures are incomplete, training is informal, contractors are poorly coordinated, or production pressure overrides safe behaviour.

Lockout and Tagout practices are essential for ensuring the safety of maintenance artisans and frontline workers. Several high-profile incidents have shown that neglecting Lockout and Tagout protocols can lead to severe injuries and substantial financial penalties.

How a Permit-to-Work System Protects Employee Health, Mental Well-being, and Reduces Stress and Anxiety by Preventing Workplace Incidents.

A Permit-to-Work system plays a vital role in protecting employee health, safety, and overall well-being. It is a formal process used to authorize work performed under non-routine or potentially hazardous conditions. The process includes hazard identification, risk assessment, the implementation of safety controls, effective communication, and ongoing supervision to minimize Environment, Health, Safety, and Sustainability risks.

Industrial workplaces contain numerous hazards, including welding sparks, corrosive chemicals, energized electrical equipment, confined spaces, loose valve fittings, hazardous gases, and many others. If these hazards are not properly identified and controlled, seemingly minor incidents can escalate into Major Accident Hazards, resulting in serious consequences for employee safety, health, and well-being.

Occupational Incidents and Diseases refer to harmful events or health conditions that occur as a direct result of work-related activities or environments. These can significantly impact the health, safety, and well-being of employees and must be carefully managed in any workplace.

Occupational Incidents are unplanned or unexpected events that occur during work, which lead to injuries, damage, or even fatalities. These can include accidents such as slips and falls, being struck by machinery, electrical shocks, burns, exposure to hazardous substances, or explosions. These incidents are typically caused by unsafe working conditions, human error, equipment failure, poor supervision, lack of training, or a combination of these factors. While some incidents result in minor injuries, others can be severe or even fatal, especially if proper safety measures are not in place.

Let’s talk about why it’s important to report occupational incidents and diseases, and the reasons behind this process.

Preventing workplace accidents and diseases starts with putting effective preventive measures in place. These measures rely on accurate information about past incidents such as occupational accidents, diseases, commuting accidents, and other dangerous events. That’s why it’s so important to report these issues to your supervisor as soon as they occur. Workers also play a role in supporting the development and implementation of safety improvements.

Emergency Equipment refers to any tools, apparatus, or devices that are available in the workplace.

These are used to address immediate needs in the event of an emergency. .

This includes firefighting equipment, first-aid kits, safety showers, eyewash stations, emergency lighting, and alarms.

These items are critical for mitigating the effects of accidents or unforeseen incidents until further medical or emergency assistance arrives.

First Aid is the immediate assistance provided to a person who is injured or suddenly unwell.

It is intended to prevent the condition from worsening and to preserve life.

First aid equipment typically includes bandages, gauze, antiseptics, splints, scissors, gloves, and other essential items.

These are used to handle minor injuries and to stabilize more serious conditions until professional medical help arrives.

Compensation for Occupational Injuries and Diseases.

According to the Compensation for Occupational Injuries and Diseases, employers have obligations to ensure employees are covered for work-related injuries and occupational diseases.

What is an injury on duty?

An injury on duty is any personal injury, disease or death arising out of and in the course of an employee's employment. Whether it happens in the office, on a construction site, or while travelling for work. The definition covers sudden accidents as well as occupational diseases that develop over time such as silicosis in miners.

Who is covered?

All employees who work more than 24 hours a month for an employer are covered.

The objectives of Compensation for Occupational Injuries and Diseases is to

compensate employees for work-related injuries and occupational diseases.
