| ENERGY FORMS, ENERGY SOURCES, AND GENERAL LOCKOUT TAGOUT GUIDELINES |
Some technical points for Energy Forms, Energy Sources, And General Lockout Tagout Guidelines uploaded by HSE Documents.
1. ENERGY FORM
1.1. Electricity
2. ENERGY SOURCE
2.1. Power transmission lines
2.2. Machine power cords
2.3. Motors
2.4. Solenoids
2.5. Capacitors (stored electrical energy)
2.6. Generators
2.7. Batteries
2.8. Photovoltaic arrays
3. GENERAL LOCKOUT GUIDELINE
Turn off power at the machine first (point of operation switch), and then at the main disconnect switch for the machine; lock and tag the main disconnect switch (or remove fuses from the box, and then lock and tag the box).
3.1. Fully discharge all capacitive systems e.g. cycle machine to drain power from capacitors as per the manufacturer’s instructions.
3.2. Install grounds where necessary.
3.3. Voltage removed, and absence of voltage verified.
3.4. Electrical Safety Program for more information.
4. ENERGY FORM
4.1. Fluid Pressure
5. ENERGY SOURCE
5.1. Hydraulic systems
5.2. Hydraulic presses
5.3. Rams
5.4. Cylinders
5.5. Hammers
6. GENERAL LOCKOUT GUIDELINE
6.1. Shut off, lock (with chains, built-in lockout devices, or lockout attachments), and tag valves; bleed off and blank lines as necessary.
6.2. Block any possible movement of machinery.
7. ENERGY FORM
7.1. Air Pressure
8. ENERGY SOURCE
Pneumatic systems:
8.1. Lines
8.2. Pressure reservoirs
8.3. Accumulators
8.4. Air surge tanks
8.5. Rams
8.6. Cylinders
9. GENERAL LOCKOUT GUIDELINE
9.1. Shut off, lock (with chains, built-in lockout devices, or lockout attachments), and tag valves; bleed off excess air.
9.2. If pressure cannot be relieved, block any possible movement of machinery.
10. ENERGY FORM
10.1. Kinetic Energy (energy of a moving object or materials - moving object may be powered or coasting)
11. ENERGY SOURCE
11.1. Blades
11.2. Flywheels
11.3. Materials in supply lines of bins or silos
12. GENERAL LOCKOUT GUIDELINE
12.1. Stop and block machine parts, and ensure that they do not recycle.
12.2. Review the entire cycle of mechanical motion
12.3. Ensure that all motions are stopped.
12.4. Block material from moving into the area of work and blank as required.
13. ENERGY FORM
13.1. Potential Energy (energy stored in an object with the potential for release due to its position)
14. ENERGY SOURCE
14.1. Springs
14.2. Actuators
14.3. Counterweights
14.4. Raised loads
14.5. Top or movable part of a press or lifting device
15. GENERAL LOCKOUT GUIDELINE
15.1. If possible, lower all suspended parts and loads to the lowest (rest) position, block parts that might move due to gravity; release or block stored spring energy.
16. ENERGY FORM
16.1. Pressurized liquids and gases (including steam, chemicals)
17. ENERGY SOURCE
17.1. Supply lines
17.2. Storage tanks and vessels
18. GENERAL LOCKOUT GUIDELINE
18.1. 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.
