Mechanical Power Presses and Forging · v1.0.0 · October 22, 2026

Course developed by Todd Jerome Jenkins, MS, CSP.

Learn to recognize press and forging hazards, use safeguards and report defects. Covers safe operation, die work, energy control, inspections and special PSDI duties. Fourteen audible lessons; allow about 45–60 minutes.

Online knowledge component only. Actual machine-specific instruction, supervised work, maintenance competence, energy-control training and employer verification remain separate. This course does not approve a machine design or provide PSDI certification, validation or blanket operator/maintenance qualification.

1. Identify the machine and applicable requirements

By the end: Identify the machine type, operation and applicable procedure before accepting an assignment.

A press can crush or amputate before a person can react. The point of operation is where the machine works on material. Other hazards include moving drives, feeding equipment, ejected parts, falling tooling and stored energy. Start with the actual machine, operation and worker role rather than its informal shop name.

OSHA 1910.217 addresses mechanical power presses. Its exclusions include press brakes, hydraulic and pneumatic power presses, bulldozers, hot bending and hot metal presses, forging presses and hammers, riveting machines and similar fastener applicators. Exclusion from this particular rule does not mean machinery may operate without safeguards.

Forging machines have specific requirements in 1910.218. Cold trimming presses are expressly directed to the point-of-operation safeguards in 1910.217(c), while hot trimming presses follow the specified mechanical-forging-press maintenance controls. General guarding and other applicable standards still need review for the actual equipment.

This course is general-industry safety knowledge for operators and supervisors. It does not qualify a person to design a safeguarding system, maintain every press, perform electrical work or approve a machine for production. The employer must determine applicable federal or state requirements and provide the actual manufacturer instructions, procedures and role-specific training.

Basis: 29 CFR 1910.217(a)(5); 1910.218; 1910.212

2. Train before work and maintain competence

By the end: Receive machine-specific instruction and remain within the employer’s verified task assignment.

Mechanical press operators must receive training and instruction in the safe method of work before starting a covered operation. The employer must use adequate supervision to ensure correct procedures are followed. Experience on a different press, or watching a coworker for a few minutes, does not establish understanding of this operation.

Learn the assigned mode, feeding method, safeguards, controls, safe stopping procedure, defect-reporting route and limits of your role. Explain the instructions in your own words and demonstrate the approved sequence in a controlled setting. Arrange language or access support when needed; a signature alone does not show understanding.

The employer must ensure the original and continuing competence of people who care for, inspect and maintain mechanical presses. Forging personnel must be trained for proper inspection and maintenance. These responsibilities are distinct from routine operator instruction. Do not adjust a brake, relocate a safety device or repair controls merely because you passed an operator knowledge test.

Provide further instruction when the job, tooling, machine or observed performance shows a gap. The general operator provision does not prescribe a universal annual course interval. PSDI operation has a separate at-least-annual training requirement covered later. Record the actual instruction and task limits; online completion documents only this knowledge component.

Basis: 29 CFR 1910.217(e)(3), (f)(2); 1910.218(a)(2)(iii)

3. Protect every route into the point of operation

By the end: Check that the approved guard protects every access route and report changes before operation.

The employer must provide and ensure use of point-of-operation guards or properly applied and adjusted devices for each mechanical press operation. The rule has a narrow exception where the point-of-operation opening is one-fourth inch or less. The employer must verify the actual condition; this is not a general exemption for small parts or short strokes.

A guard must prevent fingers or hands reaching through, over, under or around it. Openings must meet Table O-10, which relates opening size to distance from the danger line. The guard must not create its own pinch point, and its attachment must resist easy operator removal while allowing inspection and suitable visibility.

Fixed barriers, die enclosures and interlocked guards have different attachment and operating requirements. An interlock must prevent activation when the guard is not correctly positioned. Hinged or movable sections of an interlocked press barrier guard are not for manual feeding; permitted feeding devices are separately addressed in the rule.

Only authorized personnel with the required knowledge may adjust an adjustable barrier. If stock does not fit, a guard is loose, or an access gap appears, stop and request correction. Do not enlarge an opening, prop open a guard or tape an interlock. A machine that cycles successfully has not thereby demonstrated safe guarding.

Basis: 29 CFR 1910.217(c)(1)-(2), Table O-10

4. Match protective devices to press capability

By the end: Recognize device limitations and obtain authorized review of distance, adjustment and stopping performance.

A presence-sensing device must not be used as the point-of-operation safeguard on a full-revolution-clutch press. Such a press cannot be assumed to stop the hazardous stroke when someone interrupts a light curtain. Safeguard selection depends on the actual clutch, stopping capability, control system and operation.

Two-hand controls and two-hand trips are different. Proper two-hand controls on suitable presses require sustained actuation during the protected motion; releasing a hand stops the slide. A two-hand trip initiates a stroke and relies on its required location and cycle timing. Do not move either closer to the dies or defeat one button. Each operator needs the required separate controls or restraints.

Safety distances must be established using the applicable rule and actual machine measurements. Presence sensing and two-hand controls use stopping-time requirements; trips use different closure-time criteria. Qualified technical review must address brake monitoring and control reliability where required by 1910.217(c)(5). This lesson is not a calculation or design approval.

Pull-out devices need visual inspection and adjustment checks at each operator shift, after a new die setup and when operators change. Holdouts must prevent reaching the hazard. Sweep devices are prohibited as point-of-operation safeguards. Hand-feeding tools help place parts but never replace required guards or devices; unprotected access outside a sensing field must also be guarded.

Basis: 29 CFR 1910.217(b)(13)-(14), (c)(3)-(5)

5. Use the approved mode and protect coworkers

By the end: Confirm the approved setup, work area and controls before beginning or resuming production.

Before production, confirm the machine, die, feed method, operating mode and safeguards match the approved setup. Complete assigned pre-use checks from a safe position. Know the stop controls and reporting route. Do not start if a required safeguard, single-stroke function or other critical control has an unresolved defect.

Pedals and other foot-operated devices must be protected against unintended operation under the applicable press or forging provisions. Keep material, scrap and other people from actuating controls. Never tie down a two-hand button or use continuous cycling as an improvised answer to a troublesome single-stroke operation.

Provide enough space between machines so one operator’s movement does not interfere with another. Allow room for material, workpieces, scrap and cleaning. Floors around mechanical presses must be in good condition and clear of obstructions, grease, oil and water. Coordinate multi-person work so every exposed person has the required protection.

Operate within the manufacturer’s tonnage and attachment-weight ratings. A press that can force a part through may still be overloaded. Changes in tooling, material or feed conditions require review before continued use. Report unusual motion, repeated strokes, noise or loose parts; do not adjust or troubleshoot beyond the assigned role.

Basis: 29 CFR 1910.217(b), (f)(2)-(4); 1910.218(b)(2), (c)

6. Control die setting, scrap and lubrication

By the end: Use the approved die-setting and jam-clearing procedures without reaching into uncontrolled hazards.

The employer must establish a die-setting procedure that maintains the required safeguarding. Use dies and methods that control hazards. Die changes can introduce heavy suspended loads, falling tooling, crush points and unexpected motion. Only people assigned and trained for setup should carry out the work.

Provide suitable handling equipment and secure the dies under the actual manufacturer procedure. Use die stops or equivalent means to prevent loss of control when setting or removing dies in inclined presses. Where the press is designed for turnover bars, provide spring-loaded bars as required. Do not improvise lifting attachments or reach under unsecured tooling.

The employer must provide and enforce safety blocks whenever dies are adjusted or repaired in a mechanical press. Blocking must be suitable for the machine and task and used with the applicable energy-control procedure. A block is not permission to cycle the press against it; a makeshift support can be expelled or fail.

Provide and use hand tools for freeing stuck work or scrap so employees need not reach into the point of operation. Provide scrap-handling arrangements and lubrication tools such as brushes, swabs, rolls or pressure guns to avoid reaching into hazards. Tools do not create a blanket lockout exception. If a jam cannot be cleared within the approved protected method, stop and use the authorized servicing procedure.

Basis: 29 CFR 1910.217(d)

7. Separate stopping from hazardous-energy control

By the end: Recognize stored energy and use only the employer’s authorized isolation and restoration procedure.

A stopped machine may still contain energy. Flywheels can coast; rams can fall; springs and counterbalances can move; hydraulic, pneumatic or steam systems can retain pressure. Identify the actual energy sources and the movements they can produce before servicing or maintenance begins.

A push button, selector switch, emergency stop or ordinary control-circuit interlock is not an energy-isolating device. Authorized employees must follow the employer’s machine-specific energy-control procedure: prepare and shut down, isolate, apply the required locks or tags, control stored energy and verify isolation before work. Apply suitable blocking without exposing anyone while it is installed.

The minor-servicing exception is narrow. During normal production the activity must be routine, repetitive and integral, and effective alternative protection must be provided. Calling a jam small or quick does not satisfy those conditions. The employer must establish the applicable protected method; an operator must not invent an exception at the machine.

Restoration also needs controlled steps: inspect the work area, account for people, remove devices only through the authorized procedure and notify affected workers before restart. Group work, shift changes and temporary testing require their specific arrangements. This course does not replace authorized-employee lockout training or the separate forging-machine lockout and ram-blocking requirements.

Basis: 29 CFR 1910.147; 1910.217(d)(9)(iv); 1910.218(a)(3), (d)(2), (f), (h)

8. Keep the two press-inspection duties distinct

By the end: Distinguish general inspection records, directed weekly checks and their limited exception.

The mechanical press inspection program has general and directed components. General inspections are periodic and regular and cover the press, auxiliary equipment and safeguards, including the clutch/brake, antirepeat feature and single-stroke mechanism. Complete needed maintenance or repairs before operation.

For the general component, keep a certification record for each inspection and each maintenance or repair task. It must identify the date, the person’s signature and the press serial number or other identifier. An uncompleted checklist or a machine’s purchase record does not show the required work occurred.

The directed component requires regular inspection and testing at least weekly of the clutch/brake, antirepeat and single-stroke mechanisms, with needed work completed before operation. Its maintenance tasks require certification records. The directed inspections themselves are exempt from that certification-record requirement; the same checks performed under the general component are not exempt. Presses complying with both 1910.217(b)(13) and (b)(14) are excluded from the directed component under (e)(1)(iii), not from all inspection duties.

The employer must maintain the competence of inspection and maintenance personnel. A person modifying a press must supply instructions establishing changed use and care guidelines. Record and resolve defects, update procedures and communicate changes before restart. Do not use a weekly checkbox to excuse an unsafe condition found today.

Basis: 29 CFR 1910.217(e)(1)-(3)

9. Recognize the special PSDI requirements

By the end: Keep PSDI disabled unless its complete technical, validation and training requirements are satisfied.

Presence sensing device initiation, or PSDI, uses the sensing system to initiate a press cycle. It is different from ordinary presence-sensing safeguarding. Full-revolution presses and configurations allowing a person to pass through and remain clear of the sensing field in the hazard area cannot use PSDI. Do not enable this mode just because a light curtain is installed.

Before initial use, the safety-system design and installation need the required certification and OSHA-recognized third-party validation. At least annual employer recertification and third-party revalidation follow; without them within the preceding 12 months, remove the press from PSDI service. This course neither provides that validation nor establishes that a validator is available for a proposed installation.

PSDI operators need training before first use, as needed for competence and at least annually. Cover the manufacturer’s test procedure and specified test rod, safety distance, mode function and performance, hand-tool requirements and severe consequences of bypassing safeguards. Certify the trainee identity, trainer or employer signature and completion date; retain the training certification for the employee’s employment. Maintenance personnel need initial and periodic training.

Perform required checks at each shift start and die change, including test-rod operation, safety distance and the applicable supplemental safeguards and settings. Correct failures before use. PSDI is not a die-setting or setup mode; authorized personnel must verify the post-change safeguards and adjustments. Detailed engineering, installation, checks and device-specific training under the complete paragraph remain separate from this awareness lesson.

Basis: 29 CFR 1910.217(h)(1), (9)-(13), Appendices A-C

10. Control forging-machine access and handling

By the end: Verify forging guards, tools, controls and documented inspection readiness for the actual machine.

Forging equipment can expose workers to heavy moving rams, hot metal, flying scale and tool kickback. Hammers and presses must be installed so they remain in position or on suitable supporting foundations as specified. Overhead parts must be secured or protected against falling or flying off if they fail.

Provide the means to disconnect power and lock out or make cycling controls inoperable under the specific machine provisions and applicable energy-control program. Protect foot-operated devices against unintended use. Manually operated press valves and switches must be clearly identified and readily accessible; unclear labels are a defect to resolve before relying on them.

Tongs must be long enough to clear the worker’s body during kickback and must not have sharp handle ends. Scale-removal devices must reach the full die length without putting a hand or arm between dies. Substantial rear scale guards are required on every hammer and press. Tools and PPE do not replace the required guards or safe machine condition.

Use handling equipment strong and suitably sized for die-setting operations. Train personnel for proper forging inspection and maintenance. Schedule periodic regular maintenance safety checks and frequent regular guard/protection-device inspections, retaining certification dates, inspector signatures and machine identifiers. Do not apply the mechanical-press directed-inspection record exemption to forging inspections.

Basis: 29 CFR 1910.218(a)(2)-(3), (b)-(c)

11. Apply the hammer-specific protections

By the end: Identify the hammer’s shutoff, pressure, falling-part and ram-blocking controls before assigned work.

Power-driven and gravity hammers have different failure modes. Steam and air hammers require a safety cylinder head to cushion a broken or detached rod. Steam hammers require a conveniently located quick-closing emergency valve in the admission line. It must be closed and locked off during adjustment, repair, service or die changes.

Steam cylinders need the required draining means. Air-lift hammers have corresponding safety-head and shutoff provisions, plus drain cocks on the main head and clamp cylinders. Steam and air piping must meet the incorporated requirements. Operators should report leaks, drainage problems or damaged fittings; pressure-system design and repair belong to appropriately trained personnel.

Board drop hammers need a securely fastened enclosure to stop detached or damaged boards from falling. Assemblies and fittings that can loosen and fall must be secured. Die keys and shims must use material that does not unduly crack or splinter. Do not substitute unknown scrap or continue after a retaining component becomes loose.

Block the hammer ram during die changes or other work on the hammer. The standard addresses block or wedge material, strength and construction through Table O-11. Qualified selection must consider the actual load and dimensions; the table is not permission to choose any nominal lumber size. Isolation, pressure control and suitable blocking work together and must be established without exposing a person beneath an unsupported ram.

Basis: 29 CFR 1910.218(a)(3)(iv), (b), (d)-(e), Table O-11

12. Isolate forging presses, trimmers and upsetters

By the end: Verify each machine’s required lockout, flywheel and blocking conditions before die work or maintenance.

For die changes or maintenance on a mechanical forging press, lock out the power, bring the flywheel to rest and block the ram with material meeting or exceeding the specified Table O-11 strength or dimensions. These are separate conditions. An electrically isolated motor can leave a moving flywheel or an unsupported ram hazardous.

For hydraulic forging presses, lock out the hydraulic pumps and power apparatus and block the ram with suitable material meeting the stated requirement. Follow the full energy-control procedure for residual pressure and any additional energy sources. A closed control valve or pressure gauge reading alone is not a substitute for the required isolation and blocking.

Hot trimming presses follow the mechanical-forging-press requirements in paragraph (f)(1). Cold trimming presses must be safeguarded under 1910.217(c). Identify the actual operation; do not assume all equipment called a trimming press follows one identical rule or is safe because it handles a cooler workpiece.

Upsetters need stable installation, a means to lock out power at entry and disable cycling controls, identified accessible manual controls and suitable tongs. For die changes, maintenance or other work on the machine, lock out power and ensure the flywheel is at rest. Boltheading and rivet-making equipment are referred to these upsetter provisions. Actual procedures must identify the machine-specific safe state and who may verify it.

Basis: 29 CFR 1910.218(f)-(i), Table O-11

13. Control lead, scale and supporting equipment

By the end: Identify supporting-equipment safeguards and arrange the separate exposure and task training that applies.

Forge-shop safety includes equipment around the hammer or press. Billet shears require a positive lockout device to disconnect power. Saws need the specified spark guard, at least one-eighth-inch sheet metal, positioned to stop flying sparks. Conveyor drives need the applicable guarding, and shot-blast chambers need doors or guards protecting operators.

Grinding requires PPE and compliance with the applicable abrasive-wheel requirements, including 1910.215 and the incorporated standard. Do not assume this awareness lesson qualifies someone to mount or inspect every grinding wheel. Use the actual equipment instructions and specialized training for the assigned task.

Where lead is used in forge or die shops, 1910.218 requires thermostatic heating control, exhaust for fixed lead-pot installations, good general room ventilation for portable units, appropriate PPE, covered dross containers and clean equipment, particularly control of yellow lead-oxide buildup. These provisions do not replace the separate lead-exposure standard or its monitoring, hygiene and training duties where applicable.

Assess flying scale, heat, sharp material, noise and airborne contaminants for the actual process. Use the employer’s controls, exposure evaluation and PPE selection. Keep PPE clear of entanglement hazards and do not assume gloves protect against crushing. Report failed ventilation or damaged guards before continuing the affected work; this course is not complete lead, respiratory, hearing or abrasive-wheel qualification.

Basis: 29 CFR 1910.218(a)(1), (j); related PPE, exposure and machine standards

14. Report injuries and verify workplace readiness

By the end: Demonstrate actual workplace understanding and use the correct emergency and employer reporting routes.

For an injury or dangerous malfunction, stop safely, summon the workplace emergency response and keep others clear. Do not improvise a rescue by reaching into uncontrolled machinery. Trained responders need controlled access and energy isolation. Report near misses and defects promptly so the cause can be corrected before restart.

Under 1910.217(g), employers must report all point-of-operation injuries to operators or other employees within 30 days through the specified federal or state-plan route. The report covers employer and employee details, injury and task, clutch, safeguards, cause, feeding, actuation and operator protection. PSDI also requires notification to the recognized validator within five days of a point-of-operation injury while used in that mode.

The 30-day press report does not replace faster 1904.39 reporting: eight hours for a reportable work-related fatality and 24 hours for a reportable inpatient hospitalization, amputation or eye loss. That rule has event windows and knowledge-based timing provisions; the employer must apply them promptly, not wait for a complete investigation. Report emergencies internally immediately.

Before assignment, verify actual machine instruction, approved safeguards, safe operating sequence, stopping/reporting, and the employee’s task limits. Record observations, corrections and restrictions, separate from the online score. Keep operator training, maintenance competence, inspection certification and PSDI training/system validation evidence distinct. This course awards no blanket authorization to operate, set up, repair or validate a press.

Basis: 29 CFR 1910.217(f)-(h); 1910.218(a)(2); 1904.39
