What is a permit ?

​

• It’s a part of safe system of work to control high risk activities, such as hot work, confined spaces, excavation, work on electrical equipment.

​

• It ensures that all risk have been identified, all the precautions have been put in place before, during and after the work, also it ensures that appropriate information has been communicated to all relevant parties.

PERMIT TO WORK

Permit Operation & Application:

​

PTW is a formal documents specifying the work to be done, hazards, and the precautions to be taken. The permits provides a clear written record, signed by a responsible person, supervisor, that all foreseeable hazards have been considered and all the necessary actions have been taken. It must be in the possession of the person in charge of the work before work can commence.

General Instructions

​

​

Lock Out and Tag Out

Six Steps

Step 1: Preparation for LOTO

The first step of the locking and tagging out is the preparation phase. The SAP & AP must investigate and obtain a complete understanding of all kinds of hazardous energy that needs to be controlled. It is important to identify the particular hazards and of course, intends for the controlling or monitoring that energy. CP can also request for certain isolations pertaining to the nature of the job.

Step 2: Shut Down the equipment

With the planning complete, the actual or exact process of powering down and shutting off machines starts.

Shutting off command is initiated by a Control Person. An AP can also do the same if the equipment to be isolated is running on local state and if SAP nominates him.

Step 3: Isolate the Equipment

The next step of the Lockout/Tagout procedure is to isolate the machine and or the equipment from any source of energy. It starts with isolation from Electrical source of the equipment and draining / earthing of the power source if deemed necessary as per SAP instructions/IC certificate. Afterwards, Hydraulic, pneumatic, mechanical etc. energy sources are isolated and purging / venting carried out as per isolation certificate.

​

​

Lock Out and Tag Out

Six Steps

Step 4: Lockout/Tagout

With the machine or equipment separated or isolated from its energy source, the next step or the level of LOTO system is to lock and tag out the machine or device. Proper filling of the tags with name, sign and contact number is required.

During this step, the approved or the authorized employee will attach the lockout and Tagout devices to every energy-isolating device like motor breakers, valves, emergency push buttons etc.

Step 5: Stored Energy Check – Lockout/Tagout

Even after the energy source has been separated or disconnected, in step 3 (three) of the lockout safety process, and the machine has locked & secured out.

In step 4, that doesn’t fully guarantee that there’s no hazardous energy still stored or saved within the machine or that it’s safe to perform maintenance.

At this time, it’s important to look for any hazardous energy that’s been “stored” within the machine, or any “residual” energy. During this phase, any potentially hazardous stored or residual energy must be relieved, disconnected, restrained, or made non-hazardous in some other way. For example, Again opening of purge/vent valves can address the cause effectively.

​

​

Lock Out and Tag Out

Six Steps

Step 6: Isolation Verification – Lockout/Tagout

This last step of the Lockout/Tagout safety is all about making sure. Yes, shut down or turned off the machines are done, isolated them from their root of the power, locked them out, and inspected for hazardous stored energy.

At this point, an authorized person verifies the machine or devices have been suitably isolated and de energized.

A competent person (CP) is also required to check that all desired isolations have been performed in true spirit before the commencement of work at site.

Lock Out and Tag Out

LOTO System

​

​

Lock Out and Tag Out

LOTO Sequence

1. For the application of Isolation Lock (Pad Lock) by the SAP designated person, designated person shall apply the tags & locks where applicable at the relevant isolated equipment or breaker or plant/ apparatus.
2. The keys of the Isolation Locks (Isolation Keys) are put into any selected Key Safe box.
3. Then Control Lock Key from the Key Safe box needed taken off and put into the Key Safe Cabinet and secured by the SAP.
4. One Key Safe box Lock key from the Key Safe box representing the single work section and it is to be handed over to the Competent person at the acceptance of the permit. If more than one work sections have to work on the same isolated equipment/ system then more Key Safe box Locks shall be applied one for each section at the same key safe box.

​

​

Lock Out and Tag Out

LOTO Sequence

5. The keys applied Key Safe Locks (Key Safe box Keys) shall be handed over to each competent person of each work section with the work permit having Key Safe Key # on it and shall be kept till the issuance of the permit.

 6. After the completion of the job Key Safe Keys submitted one by one to SAP by the competent person of each work section while clearing the subject permit.

7. SAP removes the Key Safe Locks and opens the Key Safe as soon as he receives Key Safe Keys with the clearance of the permits.

8. After removal of Key Safe Locks, the isolation keys can be released for de-isolation by removing the control lock at the end.

Risk Assessment

Risk

The likelihood that a hazard will cause harm in combination with the severity of injury, damage or loss that

might foreseeably occur.

Hazard

A formalized process of identifying hazards, assessing the risk that they generate and then either eliminating

or controlling the risk.

A hazard is something that can cause harm, e.g. electricity, chemicals

Risk Assessment

Risk Assessment

Objectives of Risk Assessment

The aim of risk assessment is to ensure that hazards are eliminated, or risks minimized by the correct

application of relevant standards.

​

The objectives of risk assessment are to prevent:

• Death and personal injury.

• Other types of loss incident.

• Breaches of statute law, which might lead to enforcement action and/or prosecution.

• The direct and indirect costs that follow on from accidents.

Risk Assessment

Five Steps of Risk Assessment

Risk assessment can be described as a five-step process:

​

​

​

1. Identify the hazards.

2. Identify the people who might be harmed and how.

3. Evaluate the risk and decide on precautions.

4. Record the significant findings and implement them.

5. Review and update as necessary.

Risk Assessment

Hazard Identification Methods

There are various methods that might be used to identify hazards in a workplace as part of a risk assessment process:

​

1. Inspection.
2. Task Analysis (SREDIM)

• Select the task.

• Record the steps or stages of the task.

• Evaluate the risks associated with each step.

• Develop the safe working method.

• Implement the safe working method.

• Monitor to ensure it is effective.

3. Legislation
4. Manufacture Information
5. Incident Data

Risk Assessment

Identifying the Population at Risk

When identifying people at risk, think not only of those carrying out particular activities but also of those who may be affected by those activities.

• Workers/operators
• Maintenance Staff
• Cleaners
• Contractors
• Visitors
