Can an e STOP be used for lockout?
Can an e STOP be used for lockout?
Control system devices such as stop buttons and emergency stop devices are not accepted as energy isolating devices and cannot be used for this purpose, although they may be used as part of the HECP shutdown procedure leading up to the physical isolation of the hazardous energy sources.
What devices can be used for lockout tagout?
Here are some of the types of devices available to help meet OSHA lockout/tagout standards:
- Padlocks.
- Safety tags.
- Devices.
- Lockout hasps.
- Group lockout boxes.
Is an e stop an energy isolating device?
Some common forms of energy isolation include electrical circuit breakers, disconnect switches, ball or gate valves, blind flanges, and blocks. Push buttons, e-stops, selector switches and control panels are not considered proper points for energy isolation.

What is an energy isolating device?
Energy Isolating Device: A mechanical device that physically prevents the transmission or release of energy. This includes: Valves, Breakers, Switches; Blank Flanges for piping systems; Restraining Devices to prevent movement of parts; etc.
Can interlocks be used for Loto?
By using standard safety-rated devices – such as interlock gates and e-stop buttons – a plant manager can achieve safe, reliable machine access that replaces standard LOTO procedures without violating OSHA requirements.
What is a Loto device?
Answer — LOTO (Lock Out Tag Out) is the physical restraint of all hazardous energy sources that supply power to a piece of equipment, machinery or system. Most equipment and machinery has an Energy Isolation Device. These devices are usually put into the off position to shut down the hazardous energy source.
Is an e stop a safety device?
They are not considered machine safe-guarding devices because an Emergency Stop neither detects nor prevents employee exposure to machine hazards; rather they initiate an action to stop hazardous motion when an employee recognizes a hazard and activates the Emergency Stop.
What are examples of energy isolating devices?
What do tagout devices do?
Tagout devices are warning tags attached to energy-isolating devices to warn employees not to turn on or re-energize the machine. Tagout devices are easier to remove and provide less protection. It’s best practice to use the two together.
What happens if a machine is not equipped to accommodate a lockout device?
It is the policy of the FAA that before any employee performs any servicing, modification, alteration, or maintenance on a machine or equipment where the unexpected energizing, startup, or release of stored energy could occur and cause injury, the machine or equipment shall be isolated and rendered inoperative through …
What is a push button lockout device?
Push button lockout devices prohibit access to switches and protect against accidental engagement of a machine during maintenance or repair.
Can we use the emergency stop circuits for lockout?
One of the questions I often get when helping clients with developing HECPs for their equipment is, “Can we use the emergency stop circuit for lockout?” As usual, there is a short answer and a long answer to that simple question! The short answer to this question is NO.
How do I lock out the on/off buttons on my machinery?
Lock out the on/off or emergency-stop buttons on machinery to prevent accidental or unauthorized startups, such as during maintenance. Thread the free end of the cable through the looped end and into the lockout clamping hole; pull tight and close handle to pinch the cable for a secure fit. After locking, pull the cable tight for a secure fit.
How can I prevent lockouts on my Machines?
Lock out a machine with fewer padlocks when a team is working. Carry these boxes from job to job and mount them near valves or electrical controls to save time when organizing group lockouts.
