3. Hydraulic Energy: Fluids under pressure in hydraulic systems, like those in presses and other machinery, can cause serious injury if released without warning.
4. Pneumatic Energy: Compressed air or gas can result in injuries, such as flying debris or pressurized components being released unexpectedly.
5. Thermal Energy: Hot surfaces or steam systems can cause burns or fires if energy is not properly isolated.
6. Chemical Energy: Hazardous chemicals or vapors can pose significant risks, such as exposure to toxic substances, fires, or explosions if control systems fail.

Common Lockout/Tagout Devices

The effectiveness of a Lockout/Tagout program depends largely on the proper use of devices that can prevent hazardous energy from being released. Common lockout and tagout devices include:

• Lockout Devices: These devices physically prevent the operation of energy-isolating devices such as switches, valves, and circuit breakers. The lock is applied to the device to keep it in the “off” position, making it impossible for anyone to activate the equipment while work is being performed.
• Tagout Devices: Tagout devices are warning signs that are attached to energy-isolating devices. These tags should clearly indicate that the equipment is under maintenance and should not be operated. While tagout devices do not physically prevent energy flow, they serve as a visual warning to other workers.
• Padlocks: Used as part of lockout devices, padlocks are commonly used to secure energy-isolating devices, ensuring that unauthorized personnel cannot access or start equipment during servicing.
• Valve Lockout Devices: These are used to lock valves in the closed position, preventing the accidental release of fluids or gases during maintenance.
• Circuit Breaker Lockouts: These devices prevent electrical breakers from being turned on while maintenance is being performed, protecting workers from electrical hazards.
• Hasps: Used for situations where multiple workers are involved in maintenance. A hasp allows more than one worker to place their individual locks on the same energy-isolating device.
