Safety topics for manufacturing: 10 talks for the plant floor

Short answer

Good safety topics for manufacturing are the ones tied to the machines on your floor: grinder gaps, guards, lockout at shift change, crane paths, sling checks, container labels and platform edges. Each of the 10 talks below gives the hazard, what to say, one question and the OSHA rule.

Why these ten

OSHA publishes its ten most frequently cited standards each year. On the preliminary list for fiscal year 2026, three of them are lockout/tagout, hazard communication and machine guarding. Six of the ten talks on this page sit inside those three standards.

The other four cover overhead cranes, slings and fall protection around platforms, which the plant floor meets every day.

We left out the angles already covered by the 52 safety moments, so the two pages can be used together without repeating a talk. For the procedure behind the lockout talks, see the lockout/tagout guide. The rest of the library is on the safety topics hub.

The 10 talks

Give each one at the machine it is about. Your own written procedures come first where they say more than the talk does.

  1. The two gaps on a bench grinder

    The hazard
    The wheel on the bench grinder has worn down since the rests were last set. Both gaps are wider than they were, and nobody has measured them.
    What to say
    • Two gaps get checked before you grind. The work rest is set to within 1/8 inch of the wheel.
    • The tongue guard at the top is set to within 1/4 inch of the wheel.
    • As the wheel wears, both gaps open. Someone has to close them again, and that someone needs a name.
    • A wheel is inspected and ring tested before it is mounted. A cracked wheel is not used.
    Ask the crew
    When was the work rest on our grinder last adjusted, and by whom?
    The rule

  2. Hand tools do not replace the guard

    The hazard
    The press came with a magnet stick for placing parts. Over time the stick became the protection, and the guard stayed open because it slowed the job.
    What to say
    • The point of operation is where the machine does its work on the material.
    • It is guarded so that no part of your body is in the danger zone during the operating cycle.
    • A hand tool for placing and removing parts keeps your hand out of the danger zone. It adds to the guard. It does not replace it.
    • If the guard makes the job hard to do, tell me. We change the guard or the job. We do not run without it.
    Ask the crew
    On which machine here is a hand tool doing the work a guard should be doing?
    The rule

  3. Shift change in the middle of a lockout

    The hazard
    A repair runs past the end of the shift. The mechanic who locked out takes the lock off on the way home, and for ten minutes the machine is protected by nothing.
    What to say
    • A lock is taken off by the person who put it on.
    • At shift change there is a set procedure so protection does not lapse between the person leaving and the person arriving. Many plants do it this way: the oncoming person puts their lock on before the off-going person takes theirs off. Follow what our own procedure says.
    • Nobody cuts a lock because its owner went home. Someone else can remove it only under the employer's direction, after confirming the owner is not at the facility and making reasonable efforts to reach them. The owner is told before they start work again.
    • The person leaving tells the person arriving what has been done and what is still open.
    Ask the crew
    The last time a repair ran over the shift change here, what happened to the locks?
    The rule

  4. Every person, their own lock

    The hazard
    Five people work on one line during a shutdown. One lock, the lead's, is on the main disconnect. Four people are relying on someone else's memory.
    What to say
    • In a group lockout, every authorized person puts on their own lock when they start work and takes it off when they stop.
    • One authorized person has overall responsibility for the group.
    • Your lock identifies you and is used for lockout only. It does not go on your toolbox or your locker.
    • If there is no room for your lock, stop and ask. Do not work under someone else's.
    Ask the crew
    On our last shutdown, how many people worked on the line, and how many locks were on it?
    The rule

  5. Before the machine starts again

    The hazard
    The repair is finished and production is waiting. The lock comes off and the start button is pressed while a wrench is still on the conveyor and one person is still behind the machine.
    What to say
    • Before any lock comes off, look over the work area. Tools and spare parts are out. Guards and covers are back on.
    • Check where everyone is. Nobody is in or behind the machine.
    • After the locks are off and before the start, tell the people who work on that machine that it is coming back on.
    • Then start it.
    Ask the crew
    Who do you tell before you restart this machine, and how do you know they heard you?
    The rule

  6. Crane loads do not travel over people

    The hazard
    The straight line from the rack to the machine runs over the assembly bench. The operator takes it because it is quicker.
    What to say
    • The operator avoids carrying loads over people. Plan the path around them, or ask them to move first.
    • Only people designated to run the crane run it.
    • The rated load is marked on the crane where you can read it from the floor. Know the weight of what you are lifting before you hook it.
    • No side pulls unless a responsible person has specifically authorized it. Nobody rides the hook or the load.
    • At the start of your shift, try the upper limit switch with no load on the hook.
    Ask the crew
    On our usual lift, whose workstation does the load pass over or close to?
    The rule

  7. Check the sling before the lift

    The hazard
    The web sling on the hook has been there for years. Its tag is gone, and there is a cut near one eye that everyone has seen.
    What to say
    • Slings are inspected each day before use by a competent person the company has designated. Today that is [name].
    • A sling with no legible identification marking is not used. No tag, no lift.
    • On a web sling, look for acid or caustic burns, melting or charring, snags, punctures, tears or cuts, broken or worn stitches, and distorted fittings. Any one of them takes the sling out of service.
    • Slings are not shortened with knots or bolts. Pad them where they bear on a sharp edge.
    Ask the crew
    Where does a bad sling go here so that nobody picks it up again?
    The rule

  8. Machines that walk and fans without guards

    The hazard
    A pedestal drill was moved for a floor repair and never bolted back down. Beside it a cooling fan sits at chest height with its guard off because the guard rattled.
    What to say
    • A machine designed for a fixed location is anchored so it cannot walk or move.
    • A fan with blades less than 7 feet above the floor or working level has a guard.
    • The openings in that guard are no larger than half an inch.
    • If a machine has been moved or a guard taken off, tell me before it runs again.
    Ask the crew
    Which machine or fan in this area was moved or changed in the last year, and who checked it afterwards?
    The rule

  9. Which containers need a label

    The hazard
    The day tank beside the line is topped up from drums. It has never had a label because everyone knows what is in it. The contractor who cleans it on Saturday does not.
    What to say
    • Every container of a hazardous chemical in the workplace is labelled, either with the information from the shipped label or with the product name plus words, pictures or symbols that tell you the hazards.
    • For a fixed process container, a sign, placard, process sheet or batch ticket can stand in for a label.
    • One case needs no label: a portable container you fill yourself and use yourself, right away. Immediate use means it stays under your control, only you use it, and it is used within your shift.
    • If you hand it to someone else or leave it for the next shift, it needs a label.
    Ask the crew
    Which tank, tote or jug in this area has no label because everybody knows what is in it?
    The rule

  10. Platforms above dangerous equipment

    The hazard
    The maintenance platform over the mixer is only waist high, so nobody thinks of it as a fall. The fall is into the mixer.
    What to say
    • An open side or edge 4 feet or more above the level below needs a guardrail, a safety net or personal fall protection.
    • Above dangerous equipment the 4 feet does not apply. Even on a lower platform, you are protected from falling into or onto the equipment.
    • If a rail section was lifted out to load material, it goes back before anyone else steps up.
    • A missing rail is reported the day it is seen.
    Ask the crew
    Where in this plant could someone fall onto or into a machine from a low platform?
    The rule

Numbers worth knowing by heart

Each of these is a figure from the standard, not a rule of thumb.

AB
  • Gap A: Work rest: 1/8 inch at mostA wider gap lets the work jam between the wheel and the rest, and a jammed wheel can break.
  • Gap B: Tongue guard: 1/4 inch at mostIt sits at the top of the opening and is moved in as the wheel wears down.
The two gaps from the bench grinder talk. Both open as the wheel wears, so both get reset. Drawing not to scale.

A spindle repair across the shift change

Illustrative example

This example is made up to show the shift change talk in use. A machining plant has a spindle repair that will not finish before the day shift ends.

13:10. Dana, the day shift mechanic, locks out the machine and verifies it is isolated. 14:50. Luis arrives for the afternoon shift. 14:55. Luis puts his own lock on and verifies zero energy himself. 14:58. Dana briefs him on what is done and what is still open, then takes her lock off. At no point was the machine without a lock.

18:20. Luis finishes. Tools out. Guard back on. He tells the operator the machine is coming back. His lock comes off, and then he starts it.

  1. 13:10Dana locks out the machine and verifies it is isolated.Dana lock onLuis lock off1 lock on
  2. 14:50Luis arrives for the afternoon shift.Dana lock onLuis lock off1 lock on
  3. 14:55Luis puts his own lock on and verifies zero energy himself.Dana lock onLuis lock on2 locks on

  5. 18:20Repair finished, tools out, guard on, operator told. Luis takes his lock off.Dana lock offLuis lock off0 locks on
The locks in the example, step by step. The count only reaches zero when the work is finished.

Where the action goes after the talk

A talk ends with a hazard someone has to fix. In LeanSuite that hazard gets an owner and stays open until it is closed.

FAQ

Safety topics for manufacturing: common questions

  1. Start with the hazards your machines create: guarding at the point of operation, lockout during repairs, grinder adjustment, crane and sling use, chemical labels and open edges on platforms. Then add what your own near-miss and first aid records show.

  2. On OSHA's preliminary list for fiscal year 2026, the general industry standards in the top ten are hazard communication, lockout/tagout, respiratory protection, powered industrial trucks and machine guarding. The other five are construction standards. The list covers all industries, not manufacturing alone.

  3. At least once a year. The periodic inspection is done by an authorized employee other than the ones using the procedure being inspected.

  4. The person who applied it. The standard allows removal by someone else only under the employer's direction, after verifying that the person is not at the facility and making reasonable efforts to contact them, and the person must be told before they resume work.

  5. No. A talk reminds people of one point. The lockout standard has its own training and retraining requirements, and only designated people may operate an overhead crane.
