1.PERSONAL PROTECTIVE EQUIPMENT
CSA or ANSI equivalent personal protective equipment must beworn
2 EMERGENCY
In case of an emergency, stop the equipment by pressing the red emergency stop button.
All employees should be familiar with the location of the emergency stop buttons on the equipment they operate, as their
exact location can differ from location to location (branch to branch)
LOTO (Lock Out Tag Out) Reference LOTO STD
DIFFERENT POWER RATING DISCONNECTS
ON POSITION
OFF POSITION
If any of these DISCONNECTS are in the “ON” position notify your supervisor.
ONLY THOSE WHO ARE TRAINED CAN LOCK OUT/TAGOUT
TRAINING:
Only those who have been trained on Lock Out/Tag out (LOTO) should perform LOTO.
Inform Supervisor and/or Safety Manager if any locks are missing or out of place
Please read the Corrosion Service Lock Out Tag Out Policy for more details, including disciplinary process

Lock Out Tag Out Procedure
1. Prepare For Shutdown
Everyone in the area must be informed that Lockout/Tagout will be performed and on whichmachines.
2. Identify Sources of Hazardous Energy on the machine/equipment
Assess equipment and identify the hazardous energy sources (figure 1.0), either potential or kineticand
determine the most effective method to achieve a “ZERO ENERGY STATE”. ContactManufacturing
Engineer (Julian Kalac) to help identify system shutdownprocedures.
3. Shutdown
Follow proprietary equipment and system shutdown procedures normally used to stopping the
equipment and return equipment to a “ZERO ENERGY STATE” by methods described under“General
Lockout Guidelines” in Figure 1.0. This will likely mean turning or pressing the “stop”button
4. Apply Lock and Tag Information.
Locks
— Each worker will shall obtain his/her own individually keyed lock. This is the workers ownsafety
equipment is not to be loaned. (No duplicate or master keys).
— When more than one person use a multi-hinged hasp lockout device.
Tags
Lockout tags should include the followinginformation:
— Date, Time. Workers Name(s), Department(s).
— Reason why equipment has been disconnected
5. Verify Effectiveness of Lockout
Ensure that all equipment energy sources are re-tested and a “ZERO ENERGY STATE” has ben achieved.
Use equipment specified testing devices for system shutdown confirmation such as Volt Meters, pressure
gauges, blocks, bleeding devices or cycling systemsprocedures.
6. Release From Lockout/Tagout
Before locks/tags are removed and energy is restored to the machine/equipment, inspect the work area
to ensure components are operationally intact. Each lock and tag should be removed from eachenergy-
isolating device by the worker who applied the lock andtag.

Second Person – 'Safety Monitor'
Where a worker is either working on live equipment; or
where a worker is near exposed live electrical equipment a second worker who is not engaged in the work
must be appointed by the supervisor as a 'safety monitor'.
The function of the 'safety monitor' is to:
1) warn other people in the area of the hazard; and
2) ensure that all safety precautions and procedures are complied with.
A 'safety monitor' must be:
1) informed of the duties of a 'safety monitor' and of the hazards involved in the work;
2) trained and instructed in the procedures to follow in the event of an emergency;
3) authorized to immediately stop any part of the work that the monitor considers dangerous; and
4) not have any other duties or interruptions that might interfere with the duties as 'safety
monitor'.

ENERGY FORM ENERGY SOURCE GENERAL LOCKOUT GUIDELINE
Electricity
power transmission lines;
machine power cords;
motors;
solenoids;
capacitors (stored
electrical energy)
Turn off power at machine first (i.e., at point of operation
switch), and then at the main disconnect switch for the
machine; lock and tag main disconnect switch (or remove
fuses from box, and then lock and tag box).
Fully discharge all capacitive systems (e.g., cycle machine to
drain power from capacitors) according to manufacturer’s
instructions.
Fluid pressure
hydraulic systems (e.g.,
hydraulic presses, rams,
cylinders, hammers)
Shut off, lock (with chains, built-in lockout devices, or
lockout attachments) and tag valves; bleed off and blank
lines as necessary.
Air pressure
pneumaticsystems(e.g.,
lines, pressure reservoirs,
accumulators, air surge
tanks, rams, cylinders)
Shut off, lock (with chains, built-in lockout devices, or
lockout attachments) and tag valves; bleed off excess air;
if pressure cannot be relieved, block any possible
movement of machinery.
Kinetic energy
blades;
flywheels;
materials in supply lines of
bins or silos
Stop and block machine parts (e.g., stop flywheels and
ensure that they do not recycle); review entire cycle of
mechanical motion, ensure that all motions are stopped.
Block material from moving into area of work;
Potential energy
springs (e.g., in air brake cylinders);
actuators; counter weights;
raised loads;
top or movable part of a
press or lifting device
If possible, lower all suspended parts and loads to the
lowers (rest) position, block parts that might be moved
by gravity; release or block spring energy.
Pressurized liquids
and gases
supply lines;
storage tanks and vessels
Shut off, lock (with chains, built-in lockout devices, or
lockout attachments) and tag valves; bleed off excess
liquids or gases; blank lines as necessary.
