What are the steps for isolation?
The following lock-out process is the most effective isolation procedure:
- shut down the machinery and equipment.
- identify all energy sources and other hazards.
- identify all isolation points.
- isolate all energy sources.
- control or de-energise all stored energy.
How many steps are there in a single phase safe isolation procedure?
Step 1 – Check it is safe to isolate with user. Step 2 – Prove your voltage indicator using your proving unit. Step 3 – Test the circuit you wish to isolate is powered off by checking line-neutral, line-earth and neutral-earth. Step 4 – Re-test your voltage indicator using your proving unit.
Which regulation is relevant to safe isolation?
The Electricity at Work Regulations 1989 definition of ‘isolation’ is given in regulation 12 and means the disconnection and separation of the electrical equipment from every source of electrical energy in such a way that this disconnection and separation is secure.
How do you isolate an electrical circuit?
Isolate electricity to a particular electrical appliance by turning the switch on the wall socket to the “Off” position. By doing so you won’t need to trip the switch or remove the fuse that connects the circuit to all the wall sockets.
Why are procedures for the removal of locks important?
An effective lockout/tag out program will help prevent: Contact with a hazard while performing tasks that require the removal, by-passing, or deactivation of safeguarding devices. The unintended release of hazardous energy (including stored energy).
What is isolation in safety?
PROCEDURE The primary objective of energy isolation is to ensure all energy sources are properly isolated before starting of any maintenance or servicing job on the equipment so that the work shall be done without any injury to personnel or equipment damage.
How many tests are in 3 phase safe isolation?
3 Phase = 10 tests 1 Phase = 3 tests Re-check the approved voltage indicator device is still functional • On the same proving system as Step 5. Circuit/equipment should be safe to carry out the work.
Why do we carry out safe isolation?
Safe isolation procedures are in place to ensure that workers on site are not exposed to danger when working on or near live electrical systems. They help to standardise safer working practices throughout the industry.
Why is safe isolation important?
What are the main requirements of the Management of Health and Safety at Work Regulations?
1 Management of Health and Safety at Work Regulations 1999: require employers to carry out risk assessments, make arrangements to implement necessary measures, appoint competent people and arrange for appropriate information and training.
Why do we do safe isolation?
Safe isolation refers to the process of disconnecting an electrical installation from the rest of the circuit and testing that no current is flowing through it. The purpose of isolating an installation is to ensure the safety of the people who are working on it, preventing them from receiving an electric shock.
How do you isolate supply?
The three commonly used methods for isolation are:
- Physical power supply isolation using a media such as insulation, a dielectric medium, air gap or any other non-conductive path between conductor surfaces.
- Transformers which provide isolation through magnetically coupling the primary side to the secondary winding.
