Here Is The Instruction For The The Homework And Please The Homework

Students. We have spent some time discussing engineering controls and JHA's. Your discussion board assignment is to identify two jobs, tasks, and the hazards associated with the task. Identify a piece of machinery you interact with and the engineering control provided by the manufacturer. You are to have two examples for full credit.

The first should be of an everyday item you use and one of industrial-grade engineering control. Industrial grade meaning something you would find in a warehouse or in general industry. Be creative. You are to take pictures of the items and describe how the controls work in detail. Be sure to address if the engineering control is adequate to eliminate the hazard completely AND what changes if any should be made.

You will be critiquing the other students' work as well. This assignment WILL BE GRADED (100 points) and MUST be submitted to the discussion board by Tuesday at noon.

Introduction

Engineering controls are essential elements in industrial safety, designed to eliminate or reduce hazards associated with various tasks and machinery. Understanding how these controls operate, and their effectiveness, is vital for ensuring safe work environments. This paper explores two specific examples: an everyday item with an engineering control and an industrial-grade machinery control, analyzing their safety features and discussing potential improvements.

Example 1: Everyday Item with Engineering Control

The first example is a common handheld electric drill used in household tasks. The hazard associated with this tool primarily involves electric shock, mechanical injury from rotating parts, and dust or debris inhalation. The manufacturer incorporates several engineering controls to mitigate these hazards. For instance, the drill features an insulated handle to reduce the risk of electric shock and a safety lock mechanism that prevents accidental activation. Additionally, some models include vibration dampening systems to minimize musculoskeletal strain.

Pictures of the electric drill display the insulated handle, safety lock switch, and a ventilation port for dust collection. The insulation acts as an engineering control by preventing electric current from reaching the user in case of internal wire faults. The safety lock prevents accidental activation, which can cause injury if triggered unexpectedly. However, while these controls significantly improve safety, they do not eliminate hazards completely. Electric shocks can still occur if insulation is damaged or if the user bypasses safety features. Therefore, additional measures like regular maintenance and user training are necessary to enhance safety further.

Example 2: Industrial-Grade Machinery with Engineering Control

The second example is a conveyor belt system used in warehouse logistics. This machinery presents hazards such as entanglement, crushing injuries, and caught-in or caught-between risks. The manufacturer implements engineering controls like emergency stop buttons, guarding enclosures around moving parts, and interlock systems that shut down the belt if panels are opened.

The pictures show a conveyor system with clearly marked emergency stop buttons and guards covering the rollers and drive mechanism. These controls serve to prevent accidental contact with hazardous moving components and provide quick shutdown capabilities during emergencies. The guards act as physical barriers, effectively reducing the risk of entanglement and crushing. The emergency stop buttons allow for immediate deactivation of the machinery, which is critical in preventing serious injuries.

While these controls are effective, their adequacy in eliminating hazards entirely is limited. Human oversight is still necessary, and there is always a risk of users not engaging safety features properly. To improve safety, additional measures such as light curtains or presence sensors could be integrated to halt the conveyor in case of accidental contact before injury occurs. Regular inspection and maintenance of safety devices also ensure their proper functioning, further reducing residual risks.

Critique and Analysis

Both examples highlight the importance of engineering controls in workplace safety. The everyday drill's insulation and safety lock provide basic protective measures suitable for home use but insufficient in industrial environments where higher risks exist. Conversely, the conveyor system's physical guards and emergency stops are more robust, addressing multiple hazards associated with industrial machinery.

However, neither example can guarantee hazard elimination completely. Human error, maintenance lapses, or equipment damage can compromise control effectiveness. Therefore, engineering controls should be part of a comprehensive safety program that includes training, administrative controls, and personal protective equipment (PPE). Continuous review and upgrades of safety features are necessary to adapt to evolving hazards and technological advancements.

Conclusion

Understanding the specific engineering controls associated with both everyday items and industrial machinery demonstrates the importance of designing safety features that are effective and reliable. While current controls significantly reduce hazards, they must be supplemented with proper maintenance, staff training, and safety procedures to ensure a safe working environment. Innovations such as automation and sensor technologies hold promise for further hazard elimination in the future.
