Worked Solution & Example Answer:2.1 Name TWO vital functions of an injured person that must be checked when first aid is applied - NSC Mechanical Technology Fitting and Machining - Question 2 - 2022 - Paper 1
Step 1
Name TWO vital functions of an injured person that must be checked when first aid is applied.
Answer
When providing first aid, it is essential to check the following two vital functions of an injured person:
- Breathing: Ensure that the person is breathing adequately. If they are not, commence CPR or rescue breathing as necessary.
- Pulse: Check for a pulse to assess circulation. If there is no pulse, immediate action is required to initiate cardiopulmonary resuscitation (CPR).
Step 2
Give a reason why safety goggles must be worn when working with an angle grinder.
Answer
Safety goggles must be worn when working with an angle grinder to protect the eyes from flying debris and sparks. The high-speed operation of angle grinders can generate hazardous particles that can cause serious eye injuries.
Step 3
Name TWO types of safety guards that are used where the opening at the guillotine shears is greater than 10 mm.
Answer
When the opening at the guillotine shears exceeds 10 mm, the following two types of safety guards are commonly used:
- Fixed Guards: These are permanent barriers that prevent access to dangerous areas of the shearing mechanism.
- Interlocking Guards: These guards are designed to automatically shut off the machine if they are opened or removed, ensuring that operators cannot be exposed to the blades during operation.
Step 4
State THREE safety precautions that must be adhered to before gas welding is undertaken.
Answer
Before starting gas welding, the following three safety precautions should be strictly adhered to:
- Check Equipment: Inspect all gas cylinders, hoses, and torches for leaks or defects. Ensure that all connections are secure and functioning properly.
- Use Proper Attire: Wear appropriate protective clothing, including flame-resistant gloves, goggles, and a welding mask to protect against sparks and heat.
- Clear Workspace: Ensure that the work area is free from flammable materials and that there is adequate ventilation to prevent the accumulation of harmful gases.
Step 5
State TWO disadvantages of the product layout of machines.
Answer
The product layout of machines has several disadvantages, including:
- Inflexibility: Product layouts are often rigid and can be challenging to adapt for different products, limiting responsiveness to changing demand or product variations.
- High Initial Costs: Setting up a product layout can be expensive due to the need for specialized equipment and the maintenance of specific workflows, potentially increasing overall production costs.
