What are the three basic means of safeguarding machinery?

What are the three basic means of safeguarding machinery?

They are:

• Guards – these are physical barriers that prevent contact.
• Devices – these limit or prevent access to the hazardous area.
• Automated Feeding and Ejection Mechanisms – These eliminate the operator’s exposure to the point of operation while handling stock (materials).

What are some types of machine safeguarding?

The most common types of machine guards are:

• Fixed guards.
• Interlocking guards.
• Adjustable guards.
• Self-adjusting guards.

What is safeguarding of machinery?

The CSA standard Z432 Safeguarding of machinery defines safeguarding as: “… protective measures consisting of the use of specific technical means, called safeguards (guards, protective-devices), to protect workers from hazards that cannot be reasonably removed or sufficiently limited by design.”

What are the four basic principles of machine safeguarding?

Requirements For Safeguards 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.

What are the two 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 are some basic safeguarding methods?

Methods of Machine Safeguarding

• Guards. Guards are barriers which prevent access to danger areas.
• Devices. Aside from guards, another common safeguarding method is that of safety devices, a few of which include:
• Safeguarding By Location Or Distance.
• Feeding And Ejection Methods.
• Miscellaneous Aids.

What is an example of a safeguarding device?

Safeguarding devices include a number of alternatives to guards, such as interlocks, two-hand controls, and electronic presence- sensing devices, such as light curtains and pressure-sensitive mats.

What do safeguarding devices do to protect worker?

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.

What are the two types of primary safeguarding methods?

Why it is not safe to use a machine with a guard not in place?

They must be firmly secured to the machine. The guard should ensure that no objects can fall into moving parts. A guard cannot create a hazard such as a shear point, a jagged edge, or an unfinished surface that could cause a laceration.
