Workplace safety: A guide to rules, hazards and best practices

In the modern workplace, where heavy, complex and automated machinery is often found alongside sensitive and potentially dangerous materials. Therefore, creating and maintaining a safe workplace has evolved from a reactionary function to a proactive discipline. 

Enforced by strict regulations—with penalties ranging from monetary fines to total shutdowns—workplace safety has matured to entail both general and specific safety protocols across all industries. These protocols aim to foster a culture of safety in which safety is encouraged and the transparent reporting of safety concerns and violations is not only tolerated, but facilitated and respected.

Cultivating a workplace climate where health and safety are prioritized over raw productive output is a foundational goal for establishing safe working environments and preventing injuries. 

Workplace safety is a major concern among all types of businesses. Therefore, it has grown into a major industry unto itself. The Liberty Mutual 2025 Workplace Safety Index found that US businesses spend more than USD 1 billion per week on workplace injuries. Over the course of a year, these costs exceed USD 58 billion. The top 10 causes cost US businesses USD 50.87 billion per year or 86.55% of the total.

In the United States, there are three main regulatory guidelines that impact workplace safety. These guidelines are the Fair Labor Standards Act (FLSA), the Mine Safety and Health Act (MSHA) and the Occupational Safety and Health Act (OSHA).

States also have their own statutes in place—OSHA-approved state plans like the New York Occupational Safety and Health Standard, the California Occupational Safety and Health Act (CAL/OSHA) and California Labor Code and the Indiana Division of Occupational Health Compliance (IOSHA).

A brief history of US labor laws follows:

• 1911 - The Factory Investigating Commission: Following the tragic—and preventable—Triangle Shirtwaist Factory fire, New York passed dozens of new labor laws between 1912 and 1914. The disaster killed 146 garment workers and exposed the dangerous conditions common in factories at the time. The new laws strengthened fire safety requirements, established sanitation standards and regulated working hours and conditions for women and children.
• 1938 - The Fair Labor Standards Act: President Roosevelt was inspired by his home state’s response to the Triangle Shirtwaist Factory and widespread exploitative labor practices common during the Great Depression. As a result, he enacted the Fair Labor Standards Act (FLSA) as part of his New Deal legislation. The FLSA established a federal minimum wage, maximum hours and prohibitions on oppressive child labor. Every private employer that engages in interstate commerce is subject to the FLSA.
• 1970 - The Occupational Safety and Health Act: After continually updating existing labor laws through amendments, the US eventually enacted the Occupational Safety and Health Administration Act (OSHA) under the Department of Labor. Employers must also comply with the General Duty Clause of the OSH Act, which requires them to keep their workplaces free of serious recognized hazards.

As an entity, OSHA is responsible for enforcing legally mandated workers’ rights: 

• The right to work in a safe place: Employers must keep the workplace free from known safety and health hazards, including toxic chemicals. Employees have the right to report safety concerns without being punished or treated unfairly.
• Workplace safety and health training: Employers must provide accessible safety training (in multiple languages where applicable). 
• The right to machine safety: Employers are responsible for maintaining the safe operable conditions of machinery related to business operations.
• The right to refuse to work in unsafe conditions: Employers cannot penalize, coerce or force employees to work in dangerous conditions. 
• The right to safety equipment: Employers are required to, where applicable, provide necessary personal protective equipment (PPE) and other safety tools such as gloves, harnesses and hard hats. 
• The right to report: Employees have the right to report unsafe conditions to OSHA and request an official jobsite inspection. 
• The right to transparency: Employees have the right to review records of previous work-related injuries and illnesses at a jobsite, as well as review the results of tests and inspections. 

Internationally, the International Labour Organization (ILO) was established as part of the Treaty of Versailles in 1919. It enacted a tripartite system (governments, employers, workers) to negotiate binding conventions on issues like hours of work, minimum age and maternity protection.

ILO’s 1944 Declaration of Philadelphia and later UN alignment in 1946 anchored labor rights in the broader human rights framework. Together, they expanded standards on freedom of association, equal pay and the abolition of forced and child labor.   

Promoting workplace safety offers several benefits. Specifically, investing in workplace safety has been proven to increase productivity and quality.

Writing in the MIT Sloan Management Review, former OSHA assistant secretary of labor and professor at the Milken Institute School of Public Health at George Washington University, David Michaels, Ph.D. attests, “I have seen very clearly that worker safety and operational excellence are inseparable, a conclusion supported by academic research.”

The EcoOnline’s North America 2026 Workplace Safety Report further supports this conclusion, reporting that 92% of workers said that a safer workplace makes them more productive. The report also found that 78% would consider leaving a job they felt was unsafe.

A report published in the journal Safety Science in February 2024 found that “Implementing OHS practices led to statistically significant improvements in employee productivity, alongside reduced hazard exposure and better workplace perceptions.”

Many studies have found that robust safety protocols deliver significant financial benefits. They reduce the direct costs of workplace injuries, including medical expenses, legal liabilities and workers’ compensation claims. They also help prevent indirect costs, such as operational downtime, equipment damage and reputational harm. Rather than simply reducing risk, strong safety policies improve operational profitability.

When implementing safety policies to mitigate risk, it is important to first define what constitutes a hazard. Hazards can be categorized into three main groups: physical, chemical and mental. 

Physical hazards result in the most common types of preventable workplace accidents. They include falls and accidents related to moving machinery, extreme temperatures, high noise levels and radiation. Mitigating physical hazards requires constant vigilance, the installation of physical barriers and guardrails and the clear demarcation of danger zones.

Physical hazards might also include risks related to ergonomic factors, such as injuries related to the performance of repetitive tasks, poorly designed workstations or prolonged sedentary activity. 

Chemical and biological hazards require specialized management strategies. These types of hazards might be invisible to the naked eye and have delayed adverse effects. Workplace hazards include biological hazards, such as viruses, bacteria, fungi and chemical hazards, such as flammable, corrosive and toxic substances.

Managing chemical hazards relies on maintaining advanced ventilation systems, strict enforcement of decontamination protocols and robust process safety management (PSM) to prevent the release of hazardous chemicals.  

Mental or psychosocial hazards result from psychosocial risk factors, including excessive workloads, poor management and toxic workplace cultures that contribute to burnout and harassment. Mental hazards are increasingly being recognized as significant contributors to chronic stress and mental fatigue, with measurable impacts on employee productivity.

Addressing mental hazards requires a holistic approach that integrates human-centric design with psychological support systems to ensure a sustainable working environment.

The following checklist provides a simple framework for improving safety in the workplace:

• Conduct and respond to regular safety inspections

• Verify the accessibility and integrity of safety equipment

• Standardize protocols 

• Leverage technology 

• Comprehensive risk assessments: Comprehensive risk assessments (CRAs) involve the systemic examination of all workplace tasks to identify potential hazards. This process involves evaluating the likelihood of an accident, the potential severity of the outcome and the adequacy of existing controls to prevent workplace accidents. When an accident is not preventable, CRAs can also assess emergency preparedness and the ability of emergency procedures to respond.   
• Pathway inspections: Ensure that all walkways are free of debris, liquid spills or tripping hazards. This practice is especially important for emergency evacuation routes and fire exits. 
• Proper lighting: Ensure that all work areas, egress routes and exits are well lit to established standards. 
• Storage safety: Regularly confirm that all onsite materials are stored and secured, especially potentially volatile chemicals or heavy equipment at risk of falling.
• Active maintenance: Safety inspections reveal equipment maintenance needs in addition to any planned maintenance. The degree of maintenance required or the potential impact of delayed maintenance, influence maintenance strategy selection. Depending on these factors, proactive maintenance strategies are preferred to reactive corrective maintenance strategies that respond to failures only after they have occurred.

• Fire prevention: Regularly confirm that fire extinguishers, smoke detectors and sprinkler systems are filled, powered, tagged, operational and accessible. Even unused fire prevention devices might need to be replaced regularly. 
• First aid stations: Ensure that medical treatment materials and supplies are fully stocked, unexpired and readily accessible. 
• Decontamination stations: When dealing with volatile chemicals, compounds and other materials, it is essential to provide easily accessible emergency irrigation systems, such as eyewash stations and showers. These health and safety measures must be regularly tested to ensure readiness and cleanliness. 
• Personal protective equipment (PPE) Personal protective equipment (PPE), such as masks, gloves, goggles and suits, must be made available and worn when handling dangerous materials. While some worksites might allow workers to provide their own PPE, all PPE must comply with regulations and undergo regular checks for efficacy, integrity and proper use.  

• Lockout/tagout: Lockout/tagout (LOTO) safety protocols dictate that machinery is isolated from all hazardous energy sources and physically locked in the off position before performing any maintenance or service. To prevent accidental startups or unexpected energy release, workers performing the lockout must attach identification tags to equipment controls. These tags identify who carried out lockout procedures and warn other workers against unwittingly starting machinery or equipment that might not be safe to operate. 
• Proper signage: Where applicable, instructional warning signs must be displayed. Any signs that are faded or out-of-date must be regularly replaced, with standardized high-visibility iconography.  
• Safety briefings: Conduct regular and mandatory briefings to ensure that all relevant staff are familiar with safety protocols and any ongoing or unique safety risks.

• Real-time monitoring: Using Internet of Things (IoT) sensors enables real-time monitoring of environmental conditions and asset health. These devices can detect hazardous gas concentrations, monitor temperature fluctuations in sensitive equipment or track the location of personnel in high-risk zones. By providing a continuous stream of data, IoT technology allows safety managers to recognize and respond to potential hazards immediately.
• Predictive analytics: By analyzing historical safety data, real-time data from monitoring devices and insights from artificial intelligence (AI) and machine learning algorithms, predictive analytics systems can identify potential hazards before they occur. By tracking variables like time of day, equipment age and staffing levels, predictive analytics shift from reactive accident mitigation to proactive accident prevention.
• Digital safety management systems: A digital safety management system (DSMS) provides a centralized repository for all safety-related documentation, including audit reports, training records and incident reporting. Through digitalization, a DSMS streamlines safety processes, ensures version control for safety manuals, automates auditing and provides leadership with a high-level dashboard of the organization’s safety performance.
