Tagout Systems Toolbox Talk

Tagout systems warn workers that equipment, panels, valves, switches, or other energy sources must not be used. A tag tells the crew who placed it, why it is there, and what work is being done. But a tag does not physically stop someone from turning equipment back on, so it must be treated seriously and used the right way.

This talk focuses on how tagout systems support lock out tag out work. The crew needs to understand when tags are used, what information belongs on them, why they must stay in place, and why no one should remove or ignore a tag that they did not place.

Why This Matters

• Tags warn workers that equipment or an energy source is not safe to operate.
• A clear tag helps prevent someone from starting equipment during service, repair, cleaning, or adjustment.
• Tags identify who is responsible for the lock out tag out and how to contact them.
• Missing or unclear tags can lead to confusion between trades, shifts, or crews.
• Tagout systems help control hazards when used with the correct lockout devices and procedures.

Common Hazards

• Using a tag without a lock when a physical lockout device is required.
• Placing a tag on the wrong breaker, valve, disconnect, plug, switch, or control point.
• Writing incomplete information, such as no name, date, reason, or contact details.
• Using damaged, faded, wet, torn, or unreadable tags.
• Removing or moving a tag placed by another worker.
• Ignoring a tag because the equipment appears shut down or the area looks clear.
• Failing to update tags when the job changes, the crew changes, or work continues into another shift.
• A tag getting covered by dust, overspray, weather protection, insulation, or stored materials so workers cannot see it.

Safety Checklist

Before Work Begins

• Confirm whether the job requires lockout, tagout, or both.
• Use only approved tags that are durable, readable, and made for lock out tag out work.
• Place tags at the correct energy-isolating point, such as the breaker, valve, disconnect, plug, or switch.
• Write the authorized worker’s name, date, reason for tagout, and contact information on the tag.
• Make sure the tag clearly says the equipment must not be operated or energized.
• Attach the tag securely so it will not fall off, blow away, or get moved by normal jobsite activity.
• Notify affected workers and nearby trades before placing tags on equipment or energy sources.
• Check that the tag matches the lockout device, procedure, and equipment being controlled.

During Work

• Keep tags visible and readable for the full length of the work.
• Do not bypass, cover, remove, or ignore any tagout warning.
• Do not operate equipment, open valves, reset breakers, or plug in cords with a tag attached.
• Check tags during the shift if weather, dust, traffic, or material storage could damage or hide them.
• Update the tag or procedure if the task, equipment, crew, or energy source changes.
• Remove only the tag you placed unless the approved removal procedure is followed.
• Communicate clearly during shift changes so tags are not misunderstood or left without control.

Crew Talking Points

• Where will tags be placed for the equipment or energy sources involved today?
• Does every tag clearly show who placed it and why it is there?
• Are tags being used with locks where physical lockout is required?
• Can all affected workers see and understand the tagout warning?
• What is the plan if work continues into another shift or another crew takes over?
• Does anyone have a question or concern about a tag, lock, control point, or energy source before work starts?

Stop Work If

• A tag is missing, unreadable, damaged, or not securely attached.
• The tag does not identify who placed it or why the equipment is tagged out.
• A tag is being used by itself when a lockout device is required.
• Someone tries to operate, energize, move, or test equipment with a tag attached.
• A tag appears to be on the wrong energy-isolating point.
• There is confusion about who owns the tag or whether the work is complete.

Final Reminder

A tag is a warning that must be respected every time. Read it, follow it, keep it visible, and never remove a tag unless you placed it or the proper procedure is followed.
