“Tools and Machine Controls” AND “Principle of Risk and Machine Guarding”

1. When using anthropometric facts to design tools and controls, what percentile data should be used in opposition to the following:

a. The opening in the treat of the of scissors or tin snips
50th
b. The height of ~y emergency stop button
5th
c. The manage of a large, heavy duty screwdriver
95th
d. An customary duty chair
50th
2. What is meant ~ means of control/display ratio?
It describes the relation between the tool or control and what it accomplishes
3. Why use the conversion to an act of a Phillips-head screw driver (or like) and matching type screw instead of a accustomed slotted screwdriver (and screw)?
It provides some improved fit between the tool and the fastner. Results in a depressed risk of injury from the tool slipping disclosed of the socket.
4. Design handles in the place of a bolt cutter that will not suffer the user’s fingers to subsist pinched or hit when the cutter is closed
Needs to have ~ing insulated with offset handles or gripping walls that allow the hand to have existence held in a natural position.
5. Define the denomination hazard.
A hazard is the nearness of a risky situation or a state that is a prerequisite for a misadventure.
6. What is the purpose of prefatory hazard analysis?
The goal is to identify and eliminate hazards before they be possible to become accidents, or losses, throughout the life period of the project or activity
7. Explain why experience and related expertise are in the same state important when conducting a preliminary chance analysis.

8. Why is cost-befriend analysis so critical as a portion of hazard analysis and prevention?

9. Briefly, set forth the character of the following detailed hazard analysis methodologies:
FMEA, HAZOP, HEA, FTA, TOR.

10. What is the greatest part fundamental weakness of both FMEA and HAZOP and in what way can it be overcome?

11. Name five widely applicable hazard prevention strategies.
Design for least quantity hazard (eliminate or reduce), provide preservation devices, provide warning devices, provide peculiar procedures, and terminate...
