Question 1

Sensitized doors and gates should never be used in conjunction with industrial robots.

Accepted Answer

Sensitized doors and gates can be used in conjunction with industrial robots to ensure safety measures are in place to protect workers.

Question 2

Safeguarding involves regulations and guidelines that minimize the risk of accidents.

Accepted Answer

Safeguarding primarily involves protecting individuals from harm, abuse, or neglect, rather than focusing solely on minimizing the risk of accidents.

Question 3

All feeding and ejection systems are semiautomatic to allow the operator to intervene when necessary.

Accepted Answer

Feeding and ejection systems can be manual, semiautomatic, or fully automatic, depending on the design and purpose of the machinery. The level of operator intervention varies accordingly.

Question 4

The most common mechanical injuries include cutting, tearing, shearing, and breaking.

Accepted Answer

Cutting, tearing, shearing, and breaking are indeed the most common types of mechanical injuries.

Question 5

Choosing a machine guard or device that provides minimal protection against inadvertent contact with the hazard and is moveable by the operator provides what level of risk reduction?
A)Low level
B)Intermediate level
C)High level
D)No risk reduction

Accepted Answer

A moveable machine guard or device that provides minimal protection against inadvertent contact with the hazard is not an effective risk reduction measure. It only provides a low level of risk reduction and might not be able to prevent accidents or injuries. Therefore, choosing such a guard or device is not recommended.

Question 6

An emerging technology for improving the safety or lockout/tagout programs is known as:
A)Energy absorption systems
B)Deadbolt lockout systems
C)Permanent Electrical Safety Devices (PESDs)
D)Voltage detector systems

Accepted Answer

Permanent Electrical Safety Devices (PESDs) are an emerging technology designed to improve the safety of lockout/tagout programs. PESDs are installed directly on electrical equipment and provide continuous monitoring of circuit conditions, allowing for real-time detection and isolation of faults. This technology can help to prevent electrical accidents and improve overall workplace safety. Energy absorption systems, deadbolt lockout systems, and voltage detector systems are also technologies used in lockout/tagout programs but they are not specifically designed for improving the safety of these programs.

Question 7

Key concepts in 29 CFR 1910.147 include which of the following?
A)Safety trip device
B)Automatic ejection device
C)Lockout, lockout device, tagout, and tagout device
D)Energy control procedures

Accepted Answer

The answer of Key concepts in 29 CFR 1910.147 include...

Question 8

The best safeguard for a robot is a barrier around the perimeter of its work envelope.

Accepted Answer

This is because a physical barrier can prevent humans from entering the robot's work area, therefore reducing the risk of injury or harm caused by the robot. Other safety measures and sensors can also be implemented, but a physical barrier is considered the most effective safeguard.

Question 9

Point-of-operation devices come in a variety of types including photoelectric and radio frequency.

Accepted Answer

This statement is true. Point-of-operation devices can indeed come in different types such as photoelectric and radio frequency.

Question 10

Machine guards for all industries must meet the following minimum requirements: prevent contact, be secure, protect from falling objects, create no interference, and allows safe lubrication.

Accepted Answer

These are the basic requirements for all machine guards in order to ensure worker safety.

Question 11

Which of the following is NOT part of a company's safeguarding program?
A)Machine hazard analysis
B)Guiding principles in the company's strategic plan
C)Employee training
D)Periodic safeguarding audits

Accepted Answer

Guiding principles in a company's strategic plan may not necessarily be directly related to its safeguarding program. However, the other options (machine hazard analysis, employee training, and periodic safeguarding audits) are all common components of a safeguarding program.

Question 12

Which of the following is NOT a type of point-of-operation device?
A)Two-hand controls
B)Pneumatic
C)Safety trip
D)Electromechanical

Accepted Answer

Pneumatic refers to a type of power source, not a type of point-of-operation device. The other three choices are all types of point-of-operation devices used to ensure worker safety around machinery.

Question 13

Machine-operator contact includes flying metal chips, stock kickbacks, and chemical splashes.

Accepted Answer

Machine-operation can involve flying metal chips, stock kickbacks, and chemical splashes which can pose a physical threat to the operator.

Question 14

General requirements of 29 CFR 1910.212 include:
A)Types of machine guarding
B)Guarding the point of operation
C)Both A and B
D)Neither A nor B

Accepted Answer

29 CFR 1910.212 requires both the types of machine guarding and guarding the point of operation. Therefore, choice C (Both A and B) is the best answer.

Question 15

Entrapment is a major concern when working with robots.

Accepted Answer

Entrapment occurs when a person becomes trapped or stuck by a robot, which can cause serious injury or even death. It is important to implement safety measures to prevent entrapment when working with robots.

Question 16

The OSHA standard containing general requirements for machine guarding is 29 CFR 1935.602.

Accepted Answer

The correct OSHA standard containing general requirements for machine guarding is 29 CFR 1910.212.

Question 17

All safeguards should protect against falling objects.

Accepted Answer

Falling objects can be a serious hazard in many workplaces, so it is important to have safeguards in place to protect workers from this danger. Such safeguards may include things like hard hats, safety nets, guardrails, or personal protective equipment. By implementing these protections, employers can help prevent injuries or fatalities that might result from falling objects.

Question 18

Wireless devices are being used increasingly for risk reduction in machine operation.

Accepted Answer

Wireless devices such as sensors and monitors are being used to collect data on machine performance and identify potential risks, allowing for proactive measures to be taken to reduce the likelihood of accidents or equipment failure.

Question 19

Which of the following is NOT a characteristic of a safeguard?
A)Initiate semiautomatic ejection
B)Allow safe maintenance
C)Prevent contact
D)Create no new hazards

Accepted Answer

Initiating semiautomatic ejection is not a characteristic of a safeguard. Safeguards are meant to prevent accidents and injuries by allowing safe operation, maintenance, and preventing contact with hazardous areas. They should create no new hazards and should not include features that could cause further harm. Semiautomatic ejection is not related to any of these safeguard characteristics.
