The Importance of Safety in Engineering Works: Safety Management and Risk Prevention

Introduction

Safety engineering is dedicated to advancing science and related engineering concepts, as well as developing strategies for the complete elimination and minimization of catastrophic or accidental hazards. This field of engineering covers topics such as fundamental principles in welfare management, system safety in engineering, foundational aspects of science, methods of welfare analysis, system safety, hazard control strategies, and health management. Throughout history, individuals have sought to protect themselves from risks. As human life and well-being gained immense value in society, the importance of safety in engineering works became imperative. Modern engineers not only have the responsibility to create or invent products, but also to ensure safety. In industrial settings, managers also hold the responsibility to provide a healthy and safe environment for their employees. Safety engineering encompasses the mathematical and physical aspects of preventing damages and injuries. On the other hand, safety management pertains to the organizational and managerial aspects of prevention. Safety management involves various safety solution activities, strategies, and processes to execute safety measures. Safety engineering is a subset of safety management. Safety engineers view accidents as events influenced by multiple factors. These causal factors are categorized into two types: unsafe conditions and unsafe acts. However, relying solely on addressing unsafe acts is an inadequate approach to accident prevention. Some believe that unsafe acts play the most significant role in accident prevention. Incidents resulting in system or personal injury within a certain timeframe are considered accidental occurrences within safety management and safety engineering systems.

Safety engineering entails designing controlled working environments to prevent accidents. Engineering safety principles provide fundamental concepts and methods for reducing accidents by implementing risk management procedures. Industries and workplaces involving engineering processes, such as those using chemicals and machinery, are susceptible to accidents. This framework allows industrial designers and safety engineers to enhance essential procedures, systems, and safe equipment. Engineers provide insight, while individuals equipped with design facilities and equipment contribute to the planning process. Safety engineering not only delivers safe designs for users but also offers operational safety concepts for potential incidents related to both industrial and non-industrial settings, thereby minimizing their impact. Safety engineering is an integral part of hazard mitigation, which can be achieved through administrative controls or personal protective measures. The foundation of safety engineering relies on basic principles and rules, encompassing hazard identification, analysis, and management within human and machinery systems.

Professional safety engineers undergo specialized training, including industrial health, ergonomics, engineering hazard systems, system safety, deployment, construction and product safety, and health management. Safety engineers or safety professionals often specialize in fields such as mining engineering or industrial management, but their expertise lies in system planning and processes to protect personnel and users from harm, as well as safeguarding industrial assets from damage.

One fundamental aspect of safety engineering is hazard identification. Reliable techniques in system safety are employed to identify potential hazardous systems. These hazards relate to various physical systems and their operations, where the term 'hazard' is interchangeable with 'energy.' The exchange of energy is a primary factor leading to accidents or system damage. Hazard identification's main objective is to determine the key factors contributing to accidents. When developing a prospective hazard system, all forms of energy must be considered. The initial step in the hazard management process involves compiling potential hazards. During this step, no actions are taken to mitigate these potential hazards. In the hazard identification phase, hazards are listed, including energy hazards, voltage hazards, kinetic or impact energy hazards, potential or stored energy hazards, thermal energy hazards, acoustic energy hazards, atmospheric or geological or oceanographic energy hazards, and biological energy hazards.

Hazard Identification and Analysis

The initial step in safety engineering is the identification of hazards, where hazards are defined as factors that have the potential to cause harmful effects. Various safety techniques are employed to identify potential system hazards. Hazard identification can also be termed as energy identification. Potential hazards are associated with different physical components and their related operations. Hazards identification encompasses various types of energy-related hazards, including:

• Energy Hazards: Involves the system's hardware components.
• Voltage Hazards: Categorized as low voltage electrical hazards and high voltage electrical hazards.
• Chemical Energy Hazards: Relates to substances that are deadly, reactive, ignitable, or corrosive and used in chemical explosions.
• Kinetic or Impact Energy Hazards: Relates to the impact of objects in relative motion, such as collisions and flying objects.
• Potential or Stored Energy Hazards: Involves strain, compression, attraction, repulsion, and primarily gravity-related potential falling.
• Thermal Energy Hazards: Relates to excessive cold or heat.
• Acoustic Energy Hazards: Relates to vibrations and noise.
• Electromagnetic Energy Hazards: Relates to harmful wavelengths like microwaves, infrared, visible, ultraviolet, and x-rays.
• Atmospheric, Geologic, or Oceanographic Hazards: Relates to weather, geological events, oceanic phenomena, and wave motions.
• Biological Hazards: Relates to toxic plants, insects, and animals.

These hazards can be classified based on different engineering fields, and safety engineering principles are developed to minimize them. For instance, engineers in the construction field, such as civil engineers, face specific risks, including:

• Falls from high elevations or ladders at project work sites.
• Building collapse risks.
• Vehicle and machinery-related injuries.
• Electrical circuit leaks or heat exposure dangers.

The next step in safety engineering involves hazard analysis. During this stage, more emphasis is placed on creating a list of potential system states. To analyze dangers specific to a hazard, the risks must be identified. Three main factors are commonly used to measure risk: the severity of injury or damage, the number of people unprotected from a hazard, and the likelihood of injury or damage during a hazard event. Determining the facts about prospective risks is often contingent on the frequency of harm or damage occurrence. Accidents can be categorized into two types: predictable accidents and unpredictable accidents. In the first type, unexpected events lead to system loss, but these can be predicted and prevented through hazard identification, management, and analysis. In the second type, unexpected events also result in system loss, but they cannot be anticipated or prevented using the aforementioned strategies.

Job Safety Analysis (JSA) is a tool used to prevent accidents and injuries in the workplace. It focuses on predicting hazards and ensuring worker safety. Safety engineering is dedicated to understanding the origins and prevention of accidents, with safety professionals overseeing its major functions. Presently, safety engineering places special emphasis on prediction-based prevention of hazards.

Safety Engineering and Risk Management

Safety engineering is a practical science closely related to system engineering and is a subset thereof. The term 'safety engineering' refers to the prevention of accidents by qualified professionals in this field. The collaboration of various disciplines within safety engineering involves a diverse array of skilled personnel working to prevent accidents. Safety engineers are tasked with ensuring the safety of employees in their day-to-day activities within a business. These professionals oversee a wide range of operational processes. System failures often result from deficiencies in executing necessary functions. Faults at lower levels caused by basic component failures can lead to system-wide failures. Safety engineers employ various methods to ensure operational safety, including system design to detect faults and issues. System safety, recognized as a standard approach, is endorsed by multiple government bodies as a proactive and proven procedure. Organized safety systems and techniques underpinning system safety, backed by evidence, aim to prevent, minimize, and control risks and hazards. Safety system and software safety concepts constitute integral components of system software. Emerging industries now incorporate modern safety concepts as a key focus. In industrial settings, hazards such as heat, noise pollution, fumes, dust, mists, and radiation pose challenges. As industrial activities expand, safety engineering becomes more crucial in mitigating these hazards. Robust safety engineering practices have been established, with large industries providing specialized training to their engineers to ensure safety proficiency. Stringent regulations and protocols govern safety operations in engineering and industrial sectors, falling under the purview of safety engineering. Developing effective staff safety programs and imparting specialized safety knowledge are imperative for promoting safety awareness and understanding among employees. Often, employees perceive safety as a management responsibility. Management plays a pivotal role in assessing risk levels, forging a symbiotic relationship between system safety management and program managers.

Risk Analysis Methodology in Engineering

Risk analysis methodology in engineering hinges on probability and system analysis. This approach is typically designed based on failure statistics. While extensively applicable in engineering domains such as satellite technology and medical devices, risk management methodology is also relevant for detecting threats and malfunctions within systems. Risk management is a three-step process involving identification, evaluation, and determining the relative significance of risks. Risks manifest in various forms, including accidents, credit risk, failure in projects, natural disasters, and other unforeseen events.

Hazard Management and Risk Response

Risk management involves the assessment, examination, and decision-making process pertaining to identified risks within a given context. In engineering, risk management aids construction and development engineers in recognizing and addressing potential risks during project development. Risks embody potential issues that introduce uncertainty. Delivering high-quality projects within budget constraints exposes projects to a multitude of risks. Risk management is an integral aspect of construction management, with risk identification being a systematic effort to identify potential threats to the project plan. Professionals predict and mitigate risks by taking proactive measures. Risks can be classified into two categories: product-specific risks and generic risks. Generic risks apply universally to all projects, while product-specific risks are contingent on the technological understanding and project-specific environment. Safeguarding against risks in large-scale engineering projects can be achieved through safety education and adherence to proper engineering procedures. Safety precautions play a critical role in preventing accidents and ensuring worker well-being:

Adequate installation and secure enclosure of work sites and cavities to prevent collapse and rupture.

• Use of non-slip, electrically and thermally insulated safety shoes.
• Implementation of protective gear such as helmets, safety shoes, and glasses to ensure full-body safety.
• Clearing work surfaces and footpaths of protruding nails, binding wires, and other obstacles.
• Utilization of appropriate protective clothing based on climate conditions to prevent dehydration and ensure worker comfort.

Conclusion

We can determine that the economic processes in safety development and risk management have taken place over the last thirty years.

In the past decades, the field of security engineering has undergone various changes worldwide. The prevalence of new damages or hazards in industrial settings or workplaces is due to modern technological advancements. Traditional engineering systems focused on organized product development. However, systematic safety engineering specifically develops safety systems to address hazards or harm, even after they have occurred. This development aims to reduce assessed risks and provides an efficient way to ensure safety.

Proper training of employees in an industrial setting necessitates essential safety strategies and procedures to effectively prevent accidents, injuries, or damages during their work. Establishing a safety system, conveying safety messages, and providing professional training for that safety system are common practices to avoid dangers. Nevertheless, human errors and potential variations make this process more intricate. Risky hardware components are often easier to predict, with more accurate collapse rate measurements related to hardware system failures than estimating the likelihood of potential human errors or deviation from the authorized safety system.

Considering an industrial perspective, engineering holds the primary responsibility to ensure safety in the workplace, including pre-planned actions in the event of injuries or accidents. To establish safety in engineering as a regulating and hazard-reducing procedure, workers are commonly equipped with personal protective equipment such as gloves for hand protection, earmuffs and earplugs to prevent hearing damage from loud machinery noises, and safety glasses to shield eyes from intense light and toxic gas respirators.

For instance, when examining workplace safety in the construction sector, civil engineers and company management bear the primary responsibility for safeguarding employees' well-being amidst hazardous conditions. During construction projects, essential equipment for workers and construction instruments are thoroughly tested to minimize potential hazards.

Safety in engineering holds great significance in preventing injuries and reducing risks. To promote safety engineering, governments have introduced schemes and enforced penalties for workplaces that fail to adhere to safety measures. Undoubtedly, the advancement of technology has contributed to the enhancement of safety engineering standards.
