Hazardous Energy Control

Hazardous Energy Control
Hazardous Energy:
Any form of energy found around the worksite that poses a potential hazard.
Forms of Hazardous Energy:
The below mentioned forms of hazardous Energy could be present at worksites:
⦁ Electricity
⦁ Hydraulic Pressure,
⦁ Radiation,
⦁ Gravity
The modern machinery can utilize many types of energy, but when the machines are shut down for maintenance, that energy may not just go away, the workers can be injured when energy is released unusually, so to keep workers safe and secure, extra precaution must be taken when working with equipment. Such precaution is called Lockout Tag-out.
There are many types on LO/TO processes and programs, depending on the variety of hazardous energy present, but they all share four basic ideas that are addressed before work begins:
1. Identify potentially hazardous sources of energy.
2. Disconnect those energy sources from the equipment.
3. Apply lockout or tag-out devices to prevent temporarily re-connection.
4. Confirm that the system is safe.
LOTO systems must adhere to OSHA’s lockout Tag out and tag out rules as mentioned in 29 CFR section 1910.147. Logout tag out system is a critical initiative before any bin entry or before maintenance or other service work on unloading equipment. This OSHA (1910.147) standard is an industry’s best practice for forms to keep you safe and secure during bin entry and maintenance work activity. The grain system workforce should always analyse what controls required to be locked out before any work is done. This system of lockout tag-out reduces injuries and fatalities associated with grain handling. It's an easy and inexpensive way to avoid hazards associated with flowing grain entanglement. The electrocution lockout tag-out consists of a few simple steps to use a minimum amount of equipment and is financial. First prepare for the shutdown, identify the equipment that will be shut down and notify all affected employees everyone in the area of the equipment, and they need to understand that the equipment will be out of service for a time.
Next, disconnect all the power source and place a lock and tag on it. Do the following properly:
⦁ Also make sure that all stored energy has been dissipated in systems that are feeding into the area, bin or machinery where you are going to work.
⦁ You should also disable all energy or power sources including systems that might be dump grain or feed into a bin.
⦁ Always plan to enter after shutting off the discharged auger.
⦁ Shut off the leg that could dump grain into the bin locking out consists of placing a lock on the power source that is identified by owner recognized for lockout tag-out use only.
⦁ Don't be confused with a security lock or other common padlock tagging out involves placing a tag identified by the owner on the energy source to notify others that it is locked out and non-functional.
⦁ If multiple people are working on a piece of equipment or entering in ben, there should be one lock for each person, and one person should open for other persons.
When starting or resuming the equipment
Makes sure that you have successfully shut everything off into the area and complete all maintenance or work. Under no circumstances should anyone attempt to remove the locks and energize the equipment. Only the person performing the maintenance is to have total control over the energy source. When the work is completed, remove tools and equipment and make sure all personnel have exited. Whoever initiated the lockout tag out procedure should ensure that this task is completed and notify other workers in the area that work is completed and the equipment will once again be energized.
Caution people to remain out of the vicinity of any danger. After completing the task each worker must remove his or her padlock and tag from the energy source, and this is another way to verify that all workers have exited safely. Now start the machine and verify if it is working normally.
