GENERAL SAFETY

1. PERSONAL PROTECTIVE EQUIPMENT CSA or ANSI equivalent personal protective equipment must be worn

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

If any of these DISCONNECTS are in the “ON” position notify your supervisor.

ONLY THOSE WHO ARE TRAINED CAN LOCK OUT/TAG OUT

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 which machines.

2. Identify Sources of Hazardous Energy on the machine/equipment Assess equipment and identify the hazardous energy sources (figure 1.0), either potential or kinetic and

determine the most effective method to achieve a “ZERO ENERGY STATE”. Contact Manufacturing

Engineer (Julian Kalac) to help identify system shutdown procedures.

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 own safety 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 following information: — 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 systems procedures.

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 each energy-

isolating device by the worker who applied the lock and tag.

FIGURE 1

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

pneumatic systems (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.
