Primary Safeguarding Methods Two primary methods are used to safeguard machines: guards and some types of safeguarding devices. Guards provide physical barriers that prevent access to danger areas.
What is point of operation?
Point of operation is the area on a machine where work is actually performed upon the material being processed.

Which of the following is the definition of point of operation quizlet?
Question 2: The point of operation is the area on a machine where the work is performed. If a machine’s point of operation exposes an employee to injury, it must be guarded.
What are the primary types of machine related hazards?
- moving parts (e.g., risk of injuries from entanglement, friction, abrasion, cutting, severing, shearing, stabbing, puncturing, impact, crushing, drawing-in or trapping, etc.)
- energy (e.g., electrical, electromagnetic, magnetic, etc.)
- heat or cold.
- noise.
- vibration.
What is the nip point?
Woodworking » Nip Points In-running nip points (or pinch points) are a special danger arising from rotating or reciprocating parts. They occur whenever machine parts move toward each other or when one part moves past a stationary object.Which of the following is the definition of point of operation OSHA?
The point of operation is where work is performed on the material, such as cutting, shaping, boring, or forming of stock. The power transmission apparatus is all components of the mechanical system which transmit energy to the part of the machine performing the work.
What is the goal of machine guarding?The purpose of machine guarding is to protect the machine operator and other employees in the work area from hazards created during the machine’s normal operation. This would include hazards of concern such as: ingoing nip points, rotating parts, reciprocating, transversing, and/or flying chips & sparks.
Article first time published onWhat are the three types of in-running nip points?
- rotating (including in-running nip points)
- reciprocating.
- transversing.
What is the purpose of machine guarding?
Machine guarding is a safety feature on or around manufacturing or other engineering equipment consisting of a shield or device covering hazardous areas of a machine to prevent contact with body parts or to control hazards like chips or sparks from exiting the machine.
What are the types of safety guards?
- Fixed guards.
- Interlocking guards.
- Adjustable guards.
- Self-adjusting guards.
What is the basic principle of machine guarding?
Any machine part, function, or process which may cause injury must be safeguarded. Where the operation of a machine or accidental contact with it can injure the operator or others in the vicinity, the hazards must either be eliminated or controlled. If it moves, it merits your attention!
What are the different types of guards OSHA quizlet?
- Fixed guard. Provides a barrier – a permanent part of the machine, preferable to all other types of guards.
- Interlocked Guard. …
- Adjustable Guard. …
- Self-Adjusting Guard. …
- Pullback Device. …
- Restraint Device. …
- Safety Tripwire Cables. …
- Two-Hand Control.
What are the three basic areas of a machine that require safeguarding quizlet?
All machines consist of three fundamental areas – the point of operation, the power transmission device and the operating controls. Machine safeguarding helps protect workers from preventable injuries in all three areas.
Which of the following machines usually require point of operation guarding?
Some of the machines which usually require point of operation guarding are guillotine cutters, shears, alligator shears, power presses, milling machines, power saws, jointers, portable power tools, forming rolls and calenders.
What is the purpose of a safety guard quizlet?
Guards provide physical barriers that prevent access to danger areas. Safeguarding devices either prevent or detect operator contact with the point of operation or stop potentially hazardous machine motion if any part of an individual’s body is within the hazardous portion of the machine.
What are the three main areas of a machine quizlet?
- The point of operation.
- The power transmission device.
- The operating controls.
What is the purpose of the OSHA Bloodborne Pathogens Standard quizlet?
OSHA’S bloodborne pathogens standard protects employees who work in occupations where they are at risk of exposure to blood or other potentially infectious materials. OSHA’s hazard com- munication standard protects employees who may be exposed to hazardous chemicals.
Which of these describe a method in which a bloodborne pathogen may be transmitted quizlet?
According to Eugene School District, “Bloodborne Pathogens can be transmitted when blood or body fluid from an infected person enters another person’s body via needle-sticks, human bites, cuts, abrasions, or through mucous membranes.
What types of protection is an employer required to pay for?
With few exceptions, OSHA requires employers to pay for personal protective equipment when it is used to comply with OSHA standards. These typically include: hard hats, gloves, goggles, safety shoes, safety glasses, welding helmets and goggles, face shields, chemical protective equipment and fall protection equipment.
What is a pinch point?
A pinch point is any point at which it is possible for a person or part of a person’s body to be caught between moving parts of a machine, or between the moving and stationary parts of a machine, or between material and any part of the machine.
What is Line of Fire Safety?
The term “line of fire” in safety is very common when talking about the hazards of a work task. … What is line of fire? A simple definition is being in harm’s way. Line of fire injuries occur when the path of a moving object, or the release of hazardous energy, intersects with an individual’s body.
How do you control pinch point?
- • Never walk away from a machine that is turned on or coasting.
- • Discuss and point out pinch point hazards as part of your risk assessment and toolbox meetings.
- • Ensure workers use all necessary PPE.
- • Keep floors clean and free of debris to help prevent trips and falls.
What advantage do Guards have that are designed and built by the user?
Guards designed and installed by the builder offer two main advantages: They usually conform to the design and function of the machine. They can be designed to strengthen the machine in some way or to serve some additional functional purposes.
What are the 3 basic areas where safeguarding is required when dealing with mechanical hazards?
- Prevent contact – prevent worker’s body or clothing from contacting hazardous moving parts.
- Be secure – firmly secured to machine and not easily removed.
- Protect from falling objects – ensure that no objects can fall into moving parts.
Which of the following are in running nip points?
In-running nip points are frequent sites of injuries from machinery. Nip points exist where material enters a gradually narrowing opening, for example, pulling rolls, and the material is strong enough to pull body parts, such as fingers, hands, arms, and hair, into the pinch point.
Which of the following is an example of a nip point?
Nip points can occur between rotating and fixed parts which create a shearing, crushing, or abrading action. Examples are: spoked handwheels or flywheels, screw conveyors, or the periphery of an abrasive wheel and an incorrectly adjusted work rest and tongue.
What do safeguarding devices do to protect the worker OSHA?
Guards provide physical barriers that prevent access to dangerous areas. Safeguarding devices either prevent or detect operator contact with the point of operation or stop potentially hazardous machine motion if any part of a worker’s body is within the hazardous portion of the machine.
