end NOTES
Today we are going to talk about basic concepts in lockout and tagout. The shorthand for lockout/tagout is LOTO.
You will NOT be trained in performing a lockout/tagout procedure. ▼

2. Lockout/Tagout = LOTO OSHA-required program
Safeguards you from: During:
unexpected energization ∙ service and maintenance
unexpected startup ∙ installation and set-up
release of hazardous energy ∙ other activities
Training is required
LOTO is an OSHA-required program for all business where risk of injury exists during machine service and maintenance, installation and set-up, adjustment and other activities. ▼
LOTO was created to ensure that machine operators and maintenance personnel are protected from:
unexpected energization
unexpected startup of equipment
as well as unexpected release of hazardous energy. ▼
The LOTO standard has specific training requirements for all employees in a machine shop. Records of training must be kept.▼

3. LOTO hardware The lock – only 1 key The tag – employee-specific
The locking device
This is an example of a lockout kit:
The lock – it should be easily recognizable and has only 1 key issued to the owner of the lock ▼
The tag – is specific to the employee trained and authorized to use it ▼
The locking device – this is just one example of the locking devices available ▼

4. Any type of energy is potentially hazardous!
Hazardous Energy
Any type of energy is potentially hazardous!
Common forms of energy:
Electrical
Gravitational
Hydraulic
Kinetic - residual movement in rotating parts
Hazardous energy refers to energy that is released unexpectedly from a machine. This is the energy that we control through LOTO.
Any type of energy is potentially hazardous! ▼
Common forms of hazardous energy include:
Electrical
Gravitational
Hydraulic
and Kinetic – such as residual movement in moving parts. ▼

5. Importance of LOTO
Anyone working on machinery may be exposed to injuries from energy surges, machine startup, or release of energy that is stored in the equipment
In metal fabrication:
10% of fatalities due to failure to use LOTO procedures
15% of serious trauma cases are LOTO-related
Anyone working on machinery may be exposed to injuries from energy surges, machine startup, or release of energy stored in the equipment. ▼
Based on national data, in metal fabrication:
10% of fatalities are due to failure to use LOTO procedures
and 15% of serious trauma cases are also LOTO-related. ▼

6. Authorized? “Authorized” employee:
Specially trained in LOTO procedures
Allowed to lockout a piece of equipment
Allowed to restart a locked out machine
Has a LOTO lock with only 1 key
Has a LOTO tag with their picture & name on it
The LOTO standard designates two classes of employees: “authorized” and “affected”
An “authorized” employee:
must receive special training in LOTO procedures ▼
is allowed to lock out a piece of equipment ▼
is allowed to restart a locked out machine ▼
has a LOTO lock with only one key ▼
has a LOTO tag with their picture and name on it
Tell students who is authorized in LOTO at your school. ▼

7. Affected? “Affected” employee:
No LOTO responsibilities
Must recognize when LOTO is in progress
Not allowed to remove locks and tags
Not allowed to bypass locks and tags
An “affected” employee has:
No LOTO responsibilities ▼
Must recognize when LOTO is in progress ▼
Not allowed to remove locks and tags ▼
Not allowed to bypass locks and tags ▼
YOU will be an “affected” employee unless trained in LOTO ▼
YOU will be an “affected” employee unless trained in LOTO

8. Training Required for “authorized” and “affected” employees
Must be provided by the employer
Re-training must be provided when there is a change in:
Job assignment
Machinery or processes - a new hazard is present
Energy-control or LOTO procedures
OSHA standard requires that all “authorized” and “affected” employees receive training. ▼
Employers must provide this training. ▼
Re-training must be provided when there is a change in:
Job assignment
Machinery or processes that present a new hazard
Or Energy-control or LOTO procedures. ▼

9. LOTO Shut-down You - the “affected” employee - will be notified that:
LOTO is about to occur
You cannot use that machine until the person who locked it says it is safe to do so
When a LOTO procedure is about to be implemented on a piece of equipment you operate, you - the affected employee - will be notified that:
LOTO is about to occur
You cannot use that machine until the person who locked it says it is safe to do so ▼

10. Don’t Use a Machine
From the time you are told a machine is being shut down until you are told it is safe to use
If you see a lock or a tag:
Do NOT bypass it
Do not try to remove it
Do not use a machine from the time you are told it is being shut down until you are told it is safe to use. ▼
If you see a lock or a tag:
Do not bypass it
Do not try to remove it. ▼

11. When in Doubt: ASK! A life is on the line!
If you are not sure whether a piece of equipment is locked or tagged, be sure to ASK. ▼

12. Lockable Disconnects In plain view from your workstation
One for each energy source
If you notice that a disconnect was missed during machine lockout – speak up!
This is an example of a lockable disconnect. You will notice this on almost all the newer machines in the shop.
Lockable disconnects should be:
In plain view from your workstation. ▼
Present for each source of energy powering the machine ▼
If you notice that a disconnect was missed while a LOTO procedure is set-up or in progress, speak up! ▼

13. LOTO: Start-up You - the “affected” employee - will be notified that:
Equipment will be restarted – stay away!
All LOTO devices have been removed
The “authorized” employee must test the equipment to be sure it is safe, before YOU can use it.
When the LOTO procedure is completed, you – the “affected” employee will be notified that:
The equipment will be restarted. You must be safely positioned out of harm's way during reactivation.
All LOTO devices have been removed. ▼
The “authorized employee” must test the equipment to be sure it is safe, before YOU can use it. ▼

14. Posted LOTO Procedure
Ideally LOTO procedures should be posted on or near each piece of machinery. ▼

15. ? Lockout and Blocking This photo shows a press blocked open.
DISCUSSION: Do you have any concerns about the way this was done?
------ ▼
This photo shows a dangerous practice, because the block of wood can be crushed unexpectedly. ▼
So what is the proper way to block the press open? ▼
Tell students what is an appropriate way to block the press open (such as using a steel block).
Remember, never attempt to do maintenance work or change dies on a press without checking that the all energy sources have been locked and bled (if needed). ▼

16. Summary
Businesses must have a written LOTO program with step-by-step procedures for each machine
LOTO training must be provided to all employees
Only “authorized” employees can implement LOTO
YOU will be an “affected” employee
Never remove or bypass locks or tags
In summary: ▼
A shop must have a written LOTO program with step-by-step LOTO procedures for each machine. ▼
LOTO training must be provided to all employees. ▼
Only “authorized” employees can implement LOTO procedures. ▼
YOU will be an “affected” employee – unless you receive specific LOTO training. ▼
Never remove or bypass locks or tags! ▼
