Step 1
Why should the rated speed of the grinding wheel never exceed the maximum speed of the grinder?
Answer
The rated speed of the grinding wheel should never exceed the maximum speed of the grinder to avoid potential hazards, such as the wheel bursting or breaking. If it turns faster than its revolution range, it could lead to severe accidents. Additionally, exceeding this speed would compromise the effectiveness of the grinding process.
Step 2
State TWO safety precautions that should be observed while the vertical band saw is in operation.
Answer
-
Never leave the band saw unattended during operation to prevent accidents when no one is monitoring its use.
-
Always use a push stick when cutting to keep hands away from the blade and minimize the risk of injury.
Step 3
Identify the THREE stages in which first aid is applied.
Answer
-
Examination: Assessing the condition of the injured person to determine the necessary first aid measures.
-
Diagnosis: Identifying the nature of the injuries to provide appropriate treatment.
-
Treatment: Administering the necessary care to treat the injuries sustained.
Step 4
Name the TWO main categories into which the causes of accidents can be divided according to the Occupational Health and Safety Act.
Answer
-
Unsafe acts: Actions that can lead to accidents due to negligence or lack of proper procedures.
-
Unsafe conditions: Environmental or situational factors that may pose risks of accidents.
Step 5
State TWO advantages of the product workshop layout.
Answer
-
Handling of material is kept to a minimum, increasing efficiency in workflow and reducing the chance of accidents.
-
The production control process is almost automatic, which enhances productivity and minimizes the risk of human error.
