3. Employer Rights and Responsibilities
Instructor’s Notes
Employer Rights and Responsibilities
Employers have the responsibility to, at a minimum, comply with the OSH Act
Employers must perform their due diligence to find and correct safety and health hazards
New 2015 version
Employers must also:
Perform tests in the workplace, such as air sampling or noise monitoring, as required by some OSHA standards.
Provide hearing exams or other medical tests required by OSHA standards (if applicable).
Post injury/illness information so that employees can see them.
Prominently display the official OSHA "Job Safety and Health - It's the Law" poster that describes rights and responsibilities under the OSH Act; new poster issued in 2015, however, either poster is still acceptable.
AND employers MAY NOT retaliate or discriminate against workers for using their rights under the OSH Act to report hazards that could lead to or have caused a work-related injury or illness.
Graphic: This slide has a picture of the old OSHA poster and the 2015 version of the OSHA poster.

4. Worker Rights Workplace free of recognized hazards
Instructor’s Notes
Worker Rights
Workplace free of recognized hazards
Report safety and health concerns and/or injuries and illnesses without retaliation
File a discrimination complaint under Section 11 (c) of the OSH Act, which prohibits discharge or discrimination by “any person” against any employee for OSHA-related activity;
File a complaint if punished or discriminated against for acting as a “whistleblower” under the additional federal laws for which OSHA has jurisdiction.
Receive appropriate training in a language and vocabulary that workers understand
Employers have the responsibility to provide a safe workplace free from serious hazards and must follow all OSHA safety and health standards.
Employers must find and correct safety and health problems as their due diligence under the OSH Act. OSHA requires that employers first try to eliminate or reduce hazards by making feasible changes in working conditions rather than relying on personal protective equipment - a.k.a. PPE (e.g. masks, gloves, earplugs); and if an employer provides PPE, then the employer must train the employees on WHEN and HOW to use the PPE.
Any training given by the employer must be in a language that the employees can understand. An example is when an employer is giving training on procedures for how to de-energize or re-energize a piece of equipment by locking out or tagging out (LOTO) the various energy sources to prevent employee entrapment or other hazards from released energy.
Temporary workers are also entitled to the same protection against retaliation as full-time workers. Employers may not take action against employees for participating in protected workplace activities (i.e., filing a complaint, voicing concerns about workplace hazards to supervisors, etc.). Workers also can inform OSHA of other whistleblower items that OSHA enforces, which currently (2014) is 22 different whistleblower statutes covering a variety of workplaces. For more information visit whistleblowers.gov.
The whistleblower document is included in Resource Section.

5. Workers’ Rights (Continued)
Instructor’s Notes
Workers’ Rights (Continued)
Request an OSHA inspection at your facility (confidential)
Participate in an OSHA inspection
Speak to OSHA inspector in private
See OSHA citations
Request medical records, tests that measure hazards and injury/illness log
Workers can participate during an OSHA inspection. They may speak with an inspector in private without retaliation from an employer. Workers can see the OSHA citations and request medical records, tests that measure hazards and the OSHA log.
Section 11(c) of the OSH Act prohibits discharge or discrimination by any person against any employee for OSHA-related activity AND authorizes the Secretary to investigate and seek all appropriate relief against any such person. Retaliatory lay-offs or failure to refer a worker who engages in protected activity under OSHA would be grounds for the Secretary to seek remedial - including injunctive - relief in district court.
Employers may not take action against employees for participating in protected workplace activities (i.e. filing a complaint, voicing concerns about workplace hazards to supervisors, etc.). Workers also can inform OSHA of other whistleblower items that OSHA enforces, which currently (2014) is 22 different whistleblower statutes covering a variety of workplaces.

Graphic: clipart of sprockets/gears
Ask the class why they think machines aren’t guarded. Some answers you might receive are below:
No one would stick their arm, hand, finger, head, etc. in there.
No one is supposed to be back there, in there, around it while it is running.
The machine came that way; it never had a guard.
I’ve been doing it this way for twenty years without any problems.
The guard is in the way.
The inspector didn’t say anything.
It costs too much.

10. Where Machine Hazards Occur:
Point of operation
Mechanical power transmission
Other moving parts
Three of the main places machine hazards occur on equipment are at the point of operation, mechanical power transmission apparatus and other moving parts.
Point of operation – “means that point at which cutting, shaping, boring, or forming is accomplished upon the stock”
Mechanical power transmission apparatus – “all components of the mechanical system which transmit energy to the part of the machine performing the work. These components include flywheels, pulleys, belts, connecting rods, couplings, cams, spindles, chains, cranks, and gears.”
Other moving parts – any other moving parts on the equipment that cause a hazard and can cause an injury.

11. Machine Guarding Requirements
Prevent contact
Be secure
Protect from falling objects
Create no new hazards
No interference
Maintainability and accessibility
Machine guards must prevent contact, be secure, protect from falling objects, create no new hazards and not create interference for the production of the equipment. Machine Guards should also be set up to allow for easy maintenance and accessibility to the equipment. For example: install guards so that the equipment can be maintained (oiled, greased, adjusted, etc.) without removing the guards.

12. Machine Guarding Requirements Continued
Must NOT be able to reach under, through, over or around the guards or otherwise access the hazard!
It is very important that the guards once installed do not allow access to the hazardous parts by reaching under, through, over or around the guards.

13. Any Hazards?
This slide shows a picture of a rotating shaft, a rotating shaft and coupling, gears, chain and sprocket, belt and pulley, fan, bench grinder, rotating auger, punch press, shear and reciprocating piece of equipment with a person standing between the equipment that is reciprocating and a wall. These pictures all show parts of equipment that need guarding. The rotating shafts, rotating shaft and coupling, gears, chain and sprocket, belt and pulley, rotating auger, punch press and shear all need to have guarding to eliminate access. The fan has to have a guard with openings no less than ¼ inch. The grinder must have side guards, tongue guards adjusted to ¼ inch and tool rests adjusted to 1/8 inch. Access to the reciprocating machine must be eliminated through barrier guards or other means so employees can not be struck by the equipment.

14. Methods of machine safeguarding
Physical guards
Devices
Location/Distance
The three methods of safeguarding are physical guards, devices and location/distance. Physical guards provide a barrier and are a permanent part of the machine. Devices are may stop the machine if a part of the body is placed in the danger area, restrain or withdraw the operator’s hands from the danger area, require the use of both hands to control the machine to keep them out of the danger area, or provide a barrier that is synchronized with the operating cycle of the machine to prevent entry into the danger area during the hazardous part of the cycle. Location or distance is locating the machine so that employees can not enter the hazardous area and setting up the operators at a safe distance from the equipment.

15. Guards vs. Safeguarding Devices
Fixed
Interlocked
Adjustable
Self-adjusting
Presence sensing
Pullback
Restraint
Safety controls and trips
Gates
The differences between guards and safeguarding devices:
Guards are fixed, interlocked, adjustable, self-adjusting.
Devices are presence sensing, pullback, restraint, safety controls and trips and gates.

16. Fixed Guard
Provides a barrier - a permanent part of the machine, preferable to all other types of guards.
(a)(2)
As a general rule, power-transmission apparatus is best protected by fixed guards that enclose the danger area. For hazards at the point of operation, where moving parts actually perform work on stock, several kinds of safeguarding are possible.
Fixed guards provide a barrier and are a permanent part of the machine.
This shows a picture of a flywheel with a fixed guard (left). The second picture (right) shows a belt and pulley that is fully guarded with a fixed guard that is secured in place.

17. Interlocked Guard
When this type of guard is opened or removed, the tripping mechanism and/or power automatically shuts off or disengages, and the machine cannot cycle or be started until the guard is back in place.
Interlocked guard on revolving drum
An interlocked guard may use electrical, mechanical, hydraulic, or pneumatic power or any combination of these. Interlocks should not prevent “inching” by remote control, if required. Replacing the guard should not automatically restart the machine. When the interlocked guard is opened or removed, the equipment will shut down and can’t be started again until it is closed again.
This slide shows a picture of a revolving drum (equipment) with an interlocked guard that is in the opened position.

18. Adjustable Guard
Provides a barrier which may be adjusted to facilitate a variety of production operations.
Bandsaw blade adjustable guard
Adjustable guards are useful because they allow flexibility in accommodating various sizes of stock, but, because they require adjusting, they are subject to human error.
This slide shows a picture of a vertical band saw with an adjustable guard in place.

19. Self-Adjusting Guard
Provides a barrier which moves according to the size of the stock entering the danger area.
Circular table saw self-adjusting guard
Self-adjusting guards avoid the potential for human error associated with adjustable guards. They adjust on their own staying in contact with the stock.
This slide shows a picture of a circular table saw with an adjustable guard in place that raises and lowers as the piece of wood is run over the saw blade.

20. Safeguarding devices Presence sensing Pullback Restraint
Safety controls and trips
Gates
Safeguarding devices can include presence sensing, pullback, restraint, safety controls and trips and gates.

21. Presence Sensing Device
This slide shows a picture of a press with a light curtain (left) and a machine with a bump guard (right). When you hit the bump guard the equipment stops running.

22. Presence Sensing Device – Light Curtains
This slide shows a picture of an employee working on a piece of equipment with moving parts. The equipment has light curtains installed which are presence sensing devices. The picture shows red lines indicating the optical sensors between the two light curtains that will shut off the equipment when they are broken by an employers body part, tools, etc. so that the employee can not access the point of operation while it is operating.
The small graphic in the right corner shows an hand breaking the optical sensors field on light curtains. This should shut the machine down.

23. Pullbacks and Restraints
The left photo shows an employee operating a press with pullbacks installed as a safeguarding device.
The graphic on the right show restraints installed on a press brake. This graphic shows two operators so there are two restraints installed for each operator.

24. Two Hand Controls
This slide show two versions of two hand controls. One is a two hand control with rings around the controls so that employees have to push down with both hands at the same time to start the cycle. The other picture is a picture of a two hand control where the employee is putting his hands pinky side down into the two hand control slots to start the cycle.

25. Safety Tripwire Cables
Device located around the perimeter of or near the danger area
Operator must be able to reach the cable to stop the machine
Tripwire cables must be manually reset to restart the machine. These are a device (cord) that is located around the perimeter or near the danger area. When the trip wire is pulled, the equipment will stop. The operator must be able to reach the cable to stop the machine and the machine must be able to stop fast enough for this to be sufficient.
Photo shows a tripwire cable on a machine with large rollers.

26. Other Methods
Presence Sensing mats. When employees step on the mats, the equipment will stop. This shows two picture of employees feet stepping on the mat to stop the equipment. These must be set up properly and maintained.

27. Gate
Movable barrier device which protects the operator at the point of operation before the machine cycle can be started
If the gate does not fully close, machine will not function
Another potential application of this type of device is where the gate is a component of a perimeter safeguarding system. Here the gate may provide protection not only to the operator but to pedestrian traffic as well. The machine will not operate when the gate is open. When the cycle is started, the gate will close and then the machine will operate.
This shows a picture of a press with a gate guard. The first picture shows the gate open and the point of operation accessible and the second picture shows a press with the gate closed and the point of operation not accessible.
Gate Open
Gate Closed

28. Safeguarding by Location/Distance
Locate the machine or its dangerous moving parts so that they are not accessible or do not present a hazard to a worker during normal operation
Maintain a safe distance from the danger area
One approach to safeguarding by location is shown in this photo. Operator controls may be located at a safe distance from the machine if there is no reason for the operator to tend it. In this picture the person is located away from the point of operation and hazardous parts at the controller. The point of operation and hazardous parts are covered by a large guard.
Another approach is to locate the machine so that a plant design feature, such as a wall, protects the worker and other personnel. Enclosure walls or fences can also restrict access to machines. Another possible solution is to have dangerous parts located high enough to be out of the normal reach of any worker.

29. Protective Shields
These do not give complete protection from machine hazards, but do provide some protection from flying particles, splashing cutting oils, or coolants.
Miscellaneous aids, such as these, do not give complete protection from machine hazards, but may provide the operator with an extra margin of safety. Protective shields are used in two pictures here. One is on a drill press and one is on a lathe.

30. Robot Safety – ANSI/RIA R15.06 2012
Follow ANSI/RIA R for Robot Safety. You have to protect the workers from the robot parts. Employees can be struck by the robot if they enter the hazardous area. This slide shows a picture of a robot that has a gate all around the robot so no one can enter and be struck by the robot.

32. 1910.212 General Requirements for all Machines
29 CFR covers general requirements for all machines

33. (a)(1)
One or more methods of machine guarding shall be provided to protect the operator and other employees in the machine area from hazards such as those created by the point of operation, in-going nip points, rotating parts, flying chips and sparks.
29 CFR (a)(1) states employers must guard equipment that has hazards. Shows a picture of gears

34. (a)(3)(ii)
The point of operation of machines whose operation exposes an employee to injury, shall be guarded.
29 CFR (a)(3)(ii) – point of operation must be guarded.

35. (a)(5)
When the periphery of the blades of a fan is less than seven (7) feet above the floor or working level, the blades shall be guarded. The guard shall have openings no larger than 1/2 inch.
Fans less than 7 feet from the floor must be guarded. The guard must have openings no larger than ½ inch. If still accessible at or above 7 feet then they must also be guarded.
Slide shows picture of a fan.

36. (b)
Machines designed for a fixed location shall be securely anchored to prevent walking or moving.
29 CFR (b) – securely anchor equipment

37. 1910.215 Abrasive-Wheel Machinery
29 CFR covers abrasive wheel machinery

38. (a)(4)
Work rests shall be adjusted closely to the wheel with a maximum opening of one-eighth inch to prevent the work from being jammed between the wheel and the rest, which may cause wheel breakage.
Picture shows a bench grinder which has work rests in place that are within 1/8 inch of the wheel. Grinder does not have a tongue guard.

39. (b)(9)
The distance between the wheel periphery and the adjustable tongue or the end of the peripheral member at the top shall never exceed one-fourth inch.
Tongue Guard
Picture shows a bench grinder with a tongue guard and a tool rest in place. Discuss how these become out of adjustment as the grinder is used because the wheel is being ground smaller. Have to have administrative controls and disciplinary system in place to ensure the tongue guard and tool rest stay adjusted properly.
Tool Rest

40. (d)(1)
Immediately before mounting, all wheels shall be closely inspected and sounded by the user (ring test) to make sure they have not been damaged.
Discuss what ring test is. To test, wheels should be tapped gently with a light, non-metallic instrument. If the wheels sound cracked or dead, they must not be used because they could fly apart in operation. A stable and undamaged wheel, when tapped, will give a clear metallic tone or "ring.”
Illustration: Graphic shows the wheel divided into four quadrants and arrows point to where the wheel should be struck with non-metallic tool. (Source: Idaho State University. Office of Workforce Training)

41. 1910.217 Mechanical Power Presses
29 CFR addresses mechanical power presses
This will be covered in more detail for ones that pick this as an optional topic.

42. Mechanical Power Press
Picture of a mechanical power press. Notice the flywheel, point of operation and light curtains.

43. Mechanical Power Presses
Mechanical Full Revolution Clutch
Can not be disengaged during full stroke
Mechanical Part Revolution Clutch
Can be disengaged at any time during a full stroke
Guarding is dependent on which type of press
Example – Presence sensing devices or two hand controls can’t guard a full revolution – the stroke can’t be disengaged when device is activated
Discuss the differences between a full revolution and a part revolution press. A full revolution will go one full cycle regardless of guarding, controls, etc. A part revolution can be stopped during the cycle.
Discuss what guarding can be used with full revolution versus part revolution presses. Presence sensing devices will not stop a full revolution press, but will stop a part revolution press. Physical guards are used on full revolution presses.

44. Mechanical Power Presses
Periodic and regular inspections
Foot pedal protected to prevent unintended operation
Machine Guarding power transmission apparatus same as other equipment
The employer must report all point-of- operation injuries within 30 days of occurrence

(b)
Compressed air not used for cleaning except where reduced to less than 30 p.s.i. and only when effective chip guarding and PPE.
It is the employers responsibility to ensure portable power tools are in safe condition including personal tools that employees are allowed to bring in to work.
Compressed air that is used for cleaning has to be reduced to 30 pounds per square inch gauge. Compressed air used for cleaning must have chip guarding. Employees must wear the proper PPE to protect from the compressed air and flying debris.

52. Wooden Hammer
Shows a picture of a hammer with a broken wooden handle. The hammer head and part of the handle have also been painted blue. Ask the class what is the hazard with this?
This hammer could break causing flying parts to hit someone or something. Do not tape up hammers or paint them because you will not know if it is cracked or has other problems.

53. Power Tools 1910.243 (a)(1) – Portable Circular Saws Upper blade guard
Lower blade guard
Automatically returns to starting position
Portable circular saws must have an upper blade guard and a lower self adjusting blade guard.
Slide shows picture of a portable circular saw.

54. Power Tools (cont.) 1910.243(a)(3) Portable belt sanding machines
Guard nip point where belt runs onto pulley
Guard unused run of belt
Guard portable belt sanding machines at the in-running nip points where the belt runs onto the pulley. Also guard all unused portions of the belt.

55. Lockout/Tagout What is covered?
Servicing and maintenance
Normal production operations where:
Employees by-pass guard(s)
Employees place any part of their body in a hazardous area
LOTO is covered during maintenance and service activities when an employee removes a guard and puts any part of their body in a hazardous area. Discuss the difference between machine guarding (needed during normal production operations), lockout/tagout (needed for service and maintenance) and electrical safe work practices (needed for work on electrical equipment 50V or more among other situations).

56. Servicing and maintenance includes:
Setting up
Adjusting
Inspecting
Modifying
Installing
The standard applies to the control of hazardous energy when employees are involved in service or maintenance activities such as constructing, installing, setting up, adjusting, inspecting, modifying, and maintaining or servicing machines or equipment. These activities include lubricating, cleaning or unjamming machines, and making adjustments or tool changes, where the employees may be exposed to hazardous energy. Set up usually occurs before manufacturing on a machine.
The clip are reveals a mechanical device, such as a valve.

57. Energy types Electrical Mechanical Hydraulic Pneumatic Chemical
Thermal
Other
Machines run on all kinds of power, some machines may have more than one power source. There are primary sources (electrical, hydraulic, and pneumatic) and secondary sources (thermal, chemical, and gravity.
Photos and graphics: A a cluster of the various types of energy sources, such as mechanical (gears), electrical (receptacle, battery, and atom), and heat (fire).

58. Lockout/tagout requirements
Written program which includes specific written procedures
Training of employees (not just maintenance!)
Periodic review of procedures
There are three vital components of a lock out tag out program (Hazardous Energy Control Program). A written program outlines the scope, activities, and accountability for controlling the energy. Training includes many more people than maintenance. Others in the plant need at least awareness training. Periodic reviews are necessary to determine if there is a problem with the procedure and execution of the procedure.
Clip Art: Indicates a pin in the hand to write procedures for LOTO.

59. Training and re-training
Authorized employees
Recognition of hazardous energy
Type and magnitude of hazardous energy
Methods of isolating energy
How to verify isolation
Affected – Purpose and use of procedure
Other – Procedure and Prohibition from tampering
Tagout provisions
Re-training
Change in job assignment
Change in machine or process
Change in lockout/tagout procedure
Inadequacies revealed in periodic review
Employees need to be trained to ensure that they know, understand, and follow the applicable provisions of the hazardous energy control procedures. The training must cover at least three areas: aspects of the energy control program; elements of the energy control procedure relevant to the employee’s duties or assignment; and the various requirements of the OSHA standards related to lockout/tagout.
Affected employees must receive training in the purpose and use of energy-control procedures. They also need to be able to do the following: Recognize when the energy-control procedure is being used Understand the purpose of the procedure, and Understand the importance of not tampering with lockout or tagout devices and not starting or using equipment that has been locked or tagged out.
All other employees whose work operations are or may be in an area where energy-control procedures are used must receive instruction regarding the energy-control procedure and the prohibition against removing a lockout or tagout device and attempting to restart, reenergize, or operate the machinery.
Retraining is vital to LOTO program, especially if there are changes in the procedures or equipment. Retraining is also needed when the results of the audit indicate a worker has problems with the execution of the procedure.
Clip art shows the information as thoughts from an employee.

60. Other requirements Contractors? Personnel or shift changes?
The clip art reveals a worker reading the plans. It is intended to get people in the class to think about what needs to be done when contractors are working at the facility.
Ask the class what are the requirements for contractors and personnel or shift changes?
Answer: Contractors have to be protected the same as employers employees. They must either follow their own program or follow the company’s program or some combination of both. During personnel or shift changes, each employee has to be protected as they would be if they initially locked the equipment out themselves. The oncoming employee will apply their lock, then the outgoing employee can remove their lock. The oncoming employee should still check the machinery and verify isolation of all energy sources.

61. Hazardous Equipment/Machines Lockout/Tagout
