Answer :
(a) An environmental aspect and impact assessment on the activities in the case study reveals potential environmental impacts associated with semi automatic machining, manual handling processes, and waste management practices. (b) The case study can be evaluated using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) approach to identify potential hazards, assess risks, and implement appropriate controls for a safer and more sustainable operation.
(a) Environmental Aspect and Impact Assessment:
Semiautomatic Machining:
The use of machines and tools in semiautomatic machining may lead to energy consumption and noise pollution. Although it is a semi-automated process, it still requires electricity, which could have implications on carbon emissions if the energy source is not renewable. Noise pollution may affect the workers' health and the surrounding environment.
Manual Handling Processes:
Manual handling of automotive components can lead to ergonomic issues and potential injuries for workers. Improper lifting and handling techniques can result in musculoskeletal disorders, impacting the workforce's well-being and productivity.
Waste Management:
Properly managing wastes such as oil, chemicals, and other materials is essential to prevent environmental contamination. Inadequate waste disposal practices could lead to soil and water pollution, affecting ecosystems and human health.
(b) Hazard Identification, Risk Assessment, and Determining Control (HIRADC):
Hazard Identification:
Identify potential hazards associated with semiautomatic machining, manual handling processes, and waste management. These may include electric hazards, noise hazards, ergonomic hazards, chemical hazards, and environmental hazards related to waste handling.
Risk Assessment:
Assess the likelihood and severity of each identified hazard. For instance, the risk of electric shock may be higher for certain machinery, while the risk of musculoskeletal injuries can be associated with specific manual handling tasks.
Determining Control:
Implement appropriate controls to mitigate the identified risks. This may involve providing personal protective equipment (PPE) to workers, using engineering controls to reduce noise levels, promoting proper lifting techniques, ensuring proper waste segregation and disposal, and adopting eco-friendly materials wherever possible.
In conclusion, the environmental aspect and impact assessment revealed potential risks associated with semiautomatic machining, manual handling processes, and waste management.

By conducting the HIRADC process, the company can identify and address potential risks in the production process, ensuring a safer working environment for its employees and reducing the environmental impact of its operations.
(a) Environmental Aspect and Impact Assessment:
Environmental aspect and impact assessment is a process that identifies and evaluates the potential environmental impacts associated with the activities of a company. In this case study, the company assembles automotive components using semiautomatic machining processes. Let's conduct an environmental aspect and impact assessment for the activities mentioned:
Environmental Aspects:
Energy consumption: The semiautomatic machining process requires electricity, which may lead to greenhouse gas emissions and air pollution if derived from fossil fuels.
Waste generation: The production process may generate waste materials, such as metal shavings, cutting fluids, and chemicals, which need proper management to prevent pollution.
Water usage: The production process might require water for cooling and cleaning, leading to potential water consumption and discharge.
Environmental Impacts:
Air pollution: Energy consumption from electricity and potential emissions from the machining process may contribute to air pollution and greenhouse gas emissions.
Water pollution: Improper management of waste materials and chemical usage might lead to water pollution if not treated and disposed of properly.
Resource depletion: High energy consumption and water usage might lead to resource depletion, affecting the environment and natural ecosystems.
Noise pollution: The semiautomatic machining process may generate noise, which could impact the surrounding environment and workers' health.
(b) Hazard Identification, Risk Assessment, and Determining Control (HIRADC):
HIRADC is a risk management process that involves identifying hazards, assessing risks associated with those hazards, and determining control measures to mitigate or eliminate the identified risks. Let's evaluate the case study using HIRADC:
Hazard Identification:
Physical hazards: Potential hazards include the operation of semiautomatic machinery, handling heavy components, and exposure to noise and vibration.
Chemical hazards: The use of cutting fluids, oils, and chemicals in the machining process may pose chemical hazards if not handled properly.
Ergonomic hazards: Manual handling and repetitive tasks in the production process may lead to ergonomic hazards and musculoskeletal disorders for workers.
Environmental hazards: The generation and improper management of waste materials may cause environmental hazards like pollution.
Risk Assessment:
Assess the likelihood and severity of each identified hazard to determine the level of risk associated with each hazard. Consider factors like frequency, exposure, and potential consequences.
Determining Control Measures:
Implement engineering controls, such as noise-reducing measures, to minimize the exposure to hazards.
Provide personal protective equipment (PPE) to workers to protect them from physical and chemical hazards.
Implement proper waste management procedures to ensure the safe handling and disposal of waste materials.
Train workers on ergonomic practices and provide ergonomic workstations to reduce ergonomic hazards.
