Lockout/Tagout

• Using correct lockout/tagout procedures is
  essential to construction safety.
• Locking or tagging equipment and machinery is one
  of the easiest accident prevention measures to be
  taken, yet the failure to do so results in
  thousands of accidents per year.

3
LOTO Accidents

• Estimated 50,000 injuries and 120 fatalities each
  year
• Average of 24 lost workdays per accident

4
LOTO Fatalities

• Several Electricians were working on lighting for
  a new taxiway at an international airport. The
  daily airport lighting test was conducted, but no
  lockout or tagout for the circuit where the
  electricians were working had been conducted.
  One worker was fatally electrocuted.

5
Prevention

• The previous situation may have been avoided had
  proper lockout procedures been taken. A circuit
  lock, warning tag, or both could have been used
  to warn of work being done on the circuit.

6
LOTO Fatalities (cont.)

• An electrician was troubleshooting new wiring in
  a false ceiling. No lockout or tagout procedures
  were used, and the wiring was energized.
  Employee was electrocuted when his forehead came
  in contact with an energized conductor.

7
Prevention

• This was a similar situation as the previous one,
  and many lockout/tagout fatalities come from
  electrocutions.
• It was the responsibility of this employee to
  lock or tag out the circuit he was working on.
• Had this been done, responsibility would have
  been shifted to the workers around him to not
  energize the circuit until the tag had been
  removed.

Preventing Accidents

• Key terms for lockout/tagout
• Affected Person Employee whose job requires him
  or her to use equipment or machinery which has
  been locked or tagged
• Authorized Employee Person who locks out or
  tags out machines or equipment on which servicing
  or maintenance is to be performed
• Energy Isolating Device Mechanical device that
  physically prevents the transmission or release
  of energy, such as switches, circuit breakers,
  valves, push buttons, etc. These are capable of
  being locked out if they have a hasp or other
  means of attachment to which a lock can be
  attached, or if they have a self-locking
  mechanism.

Preventing Accidents (cont.)

• Have a LOTO procedure in place, and ensure that
  all management, supervisors, and employees
  implement it.
• This procedure should be standardized by either
  color, shape or size to prevent confusion among
  employees.
• Periodic inspections should be performed (reqd
  annually by OSHA) to ensure that procedure and
  standard requirements are met.
• Training by the employer includes choosing
  authorized employees who are to be trained to
  recognize potential hazards and how to lock and
  tag them, as well as ensuring that all employees
  are aware of the procedure and the prohibition of
  using locked or tagged equipment.

10
Preventing Accidents (cont.)

• Always make sure that all locks and tags are
  readily available to jobsite personnel.

11
OSHA Regulations

• Any equipment or machinery that is capable of
  being locked out, may only be tagged out if the
  employer can prove that an equal level of safety
  will be provided to employees had the lock been
  used.
• As of January 2, 1990, whenever replacement or
  major repair is performed, energy isolating
  devices must be designed to accept a lockout
  device.
• Locks or tags may not be tampered with or removed
  without authorization, and the use of locked or
  tagged equipment or machinery is prohibited until
  the lock or tag is removed by an authorized
  employee.

12
Removal

• The removal of a lock or tag may come only after
  the affected equipment or machinery has been
  inspected and verified to be in working order.
• If the lock must be removed in order to test the
  machine, remove all tools and materials from the
  area, ensure that all other employees are clear
  of the area, then remove the lock and proceed
  with testing or positioning.
• Once removed, all affected employees must be
  notified that the machine or equipment is no
  longer locked or tagged out.
