What device physically keeps the switch valve or lever in the off position?
Lockout Device: A device is a lock, block, or chain that keeps a valve or lever in the off position.
What is a lockout device?
Lockout device: Any device that uses positive means, such as a lock, blank flanges and bolted slip blinds, to hold an energy-isolating device in a safe position, thereby preventing the energizing of machinery or equipment.
Which of the following is a mechanical device such as a valve that physically prevents the transmission or release of energy?
Energy Isolating Device – any mechanical device that physically prevents the transmission or release of energy . These include electrical circuit breakers, disconnect switches, line valves, and blocks. Energy Source – any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal or other energy.
What is an energy control device?
Energy isolating control or device A mechanical device that physically prevents the transmission or release of energy. This includes, but is not limited to: Manually operated electrical circuit breakers. Disconnect switches.
Who can remove a lockout/tagout device?
The Lockout Tagout devices are finally removed from an energy isolating device, only by the worker who applied it. The removal of employees lock without his knowledge can be dangerous, as a general rule, the Lockout Tagout device should be removed by the employee himself/herself. 5.
Which is example of isolation device?
Examples of energy-isolating devices include: A manually operated electrical circuit breaker; a disconnect switch; a manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors and, in addition, no pole can be operated independently; a line valve; a block; and …
What are examples of 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.
What is a lock off procedure?
What is Lockout Tagout? Lockout Tagout (LOTO) procedures ensure that the hazardous energy sources are isolated and rendered inoperable before any maintenance work commences. A safety lock is used when the energy source is turned off to prevent it being switched on.
What is Loto system?
Lockout/tagout (LOTO) is a set of procedures that are used to ensure that equipment is shut down, inoperable, and (where relevant) de-energized. Any workplace scenario involving equipment that could lead to the inadvertent release of hazardous energy requires the use of lockout/tagout procedures.
What is a valvalve lockout device?
Valve Lockout Devices are used to close off many kinds of pressured valves to ensure that the machinery that is valve operated remains switched off while workers carry out the maintenance work. The Valve Lockout Device is attached over the operational part of the valve, before securing it in place with padlocks or hasps.
Where is the pressure relief valve on a pressure switch?
Pressure Switch Relief Valve The pressure switch relief valve, which is located on the base of the pressure switch, is plumbed into the top of the check valve with a copper or nylon tube. When the pressure switch contacts separate, a lever actuates this valve to relieve pressure that was trapped between the pump and check valve.
What are the different types of valve lockout devices?
Ball Valve Lockout Device – these lockout devices clamp over the valve lever, thereby preventing the valve from being moved. Butterfly Lockout Device – these lockout devices are similar to Ball Valve lockout devices.
What is Gategate valve lockout device?
Gate Valve Lockout Device – these lockout devices completely cover the valve thereby preventing access to the valve. They consist of 2 half moons, hinged at one side. They are placed over the valve, closed and then locked off using padlocks or hasps where more padlocks are required.
