Job Safety Analysis – JSA

Job Safety Analysis


Procedure for Job Safety Analysis (JSA)

What is JSA?


It is a tool intended to analyze each step of a task for hazard assessment followed by recommendations of actions/procedure (s) that will eliminate or reduce the workplace hazards including the risk of injury, illness, fire & explosion.

Job Safety Analysis is a safety management tool for identification and control of hazards associated with a particular job by

Systematic/safely approach to start any activity

  • Drilling down the job into simple steps.
  • Identifying the hazard associated with each step and
  • Suggesting the control measure for each hazard.


Many workers are injured or killed at the workplace every day. Ensuring the safety and health of employees is very critical to jobs and businesses. You can prevent workplace injuries and illnesses by looking at your workplace operations, establishing proper job procedures, and ensuring that all employees are trained properly.

Job Safety Analysis (JSA) is a basic tool for safety planning which is another way of preventing workplace injuries. This technique allows us to observe the job, think through the steps involved and discuss how to complete the job safely.


What Jobs are Appropriate for a JSA?

Job Safety Analysis shall be performed for all critical tasks, irrespective of nature i.e. routine or non-routine.

Priority for the jobs to be covered by JSA can be as follows.

  1. Job Safety Analysis shall be performed for all kind of jobs/ tasks, irrespective of nature i.e. routine or non-routine that has a potential to cause injury or fatality. If Standard Operating Procedures (SOP) of routine jobs are available, JSA may be avoided, however copy of Standard Operating Procedures to be attached along with the work permit copy. All the clearances to be issued ensuring SOPs and the same to be signed by permittee and issuer at site. GSI to mention clearly in permit, whether JSA is required or not.
  2. Jobs with the highest injury / illness rates / Near miss/ Fire / Explosion incidents reported.
  3. Jobs with the potential to cause severe or disabling injuries or illness or fire or explosion.
  4. Jobs in which one simple human error could lead to a severe accident, injury, fire or explosion.
  5. Jobs that are new to operation or have undergone changes in processes and procedures.
  6. Jobs complex enough to require written instructions.
  7. Infrequent jobs –complex in nature such as erection of equipment / facilities with use of cranes / hot work / work at height / entry into confined space/ excavation etc., Hydro-testing / hydro-jetting etc.
  8. Hot works inside battery area of running units.

Who is Responsible for doing JSA?

Plant Engineers/ Managers / Sectional Head / Area in-charge will be responsible to carry out Job Safety Analysis of all activities in respective units/areas involving engineers from Mechanical, Electrical, Inspection, Process, ES, F&S, HS&E, Project, Instrumentation & Civil maintenance departments, in a multidisciplinary approach, as applicable and record the observations in standard format at least one day in advance.

Engineering assistance may also be involved in JSA. The contractor supervisor may also be involved, if required. All JSA sheets are to be signed by the multidisciplinary team members and follow the recommended safety measures while executing the jobs.

The team should comprise of maximum six persons, however, it may increase occasionally. Completed JSA sheets shall be preserved by respective plant/area managers for future reference.

Plant in-charge to obtain a nomination from section heads of concerned dept. for the formation of the JSA team.

The contractor person may be involved for carrying out JSA if required. In the case of specific jobs, they have a better experience of work and they can contribute to JSA.


Team carrying out JSA should comprise of :

  • Supervisors-Frontline Personnel responsible for the job.
  • Employee/Person most familiar with job.
  • Safety Professional and/or Engineers/Technical Advisor.

Details about Job Safety Analysis Procedure

HOD of Operation Department & HOD of Concerned Maintenance Department will review and sign the JSA observation sheets for all critical jobs and ensure compliance with recommended safety measures. Compliance of the points emerged out of JSA to be noted in the JSA sheet at site signing on the extreme right column “Complied status”. Respective DGMs/ Fire & Safety will carry out random checking of JSA system compliance, take corrective action, and discuss non-compliances, deviations if any, in weekly RSM / CSM meetings/ MSCM.

JSA must be completed at least one day before the commencement of job.

The recommended safety measures from JSA shall be strictly followed by executing group while executing the jobs.

JSA after assessment, if not done for any job, the reasons for the same (say ” JSA not required”) shall be mentioned on the Work Permit Sheet.

The responsibility for implementing JSA recommendations shall be with the executing department and the Engineers-in Charge (EIC) of the respective jobs. During the course of execution of the job, if new or unforeseen hazards/risks crops up, the job shall be stopped immediately and JSA shall be revised by the JSA team afresh and shall be reviewed by the HOD of the operation department and HOD of the concerned Maintenance Department.


Completed JSA sheets shall be preserved by the respective Plant In-charge, where they were created for future reference and a copy of same will be sent to the Fire & Safety Department for the record. Also, maintain an inventory list of JSA that have been developed in respective areas. The JSA index should include the name of the task, the date the JSA was completed & the date the JSA was last revised.

Before the issue of work permit Job Safety analysis must be carried out and signed copy of JSA format to be attached along with work permit. In the work permit, the relevant JSA number shall be mentioned. During the work in progress, periodic/surprise visit by Plant Engineer/ In-Charge as per need should be ensured and status will be recorded in JSA format.

In case, job is to be carried out in Construction/Project area segregated from the Operations area or Greenfield Project/Construction, JSA shall be prepared by the team of contractor comprising of:

  • Site Supervisor/ Engineer of the contract agency.
  • RCM responsible for the execution of the job.
  • Safety Supervisor/Safety Officer deployed by consultant/ contractor for the job. (Additional person(s) familiar with the job may be included).
  • JSA procedure shall be reviewed by the concerned Client engineer & approved by concerned Engineer In-charge from Project / Engineer.

JSA Training

Team members should have undergone training on Job Safety Analysis. To train the members training shall be organized time to time at Training Dept. with help of in-house faculty as well as an external agency.

JSA Audit

Fire & Safety department shall carry out an audit of JSA System compliance in all areas on a quarterly basis and bring out non-compliances, deficiencies, if any, to the notice of higher management. Such observations shall also be presented in monthly Safety meetings in a structured manner for discussion and improvement. This is in addition to a system audit.


Involvement of Employees in JSA

  • Employees of a given working area, performing the said job, shall be involved in all phases of the JSA, i.e. from reviewing the job steps / procedures to discussing potential hazards and recommended solutions.
  • Among these employees a(or a group) willing & experienced employee(s) should be selected for observation of the task.
  • Once an experienced and willing employee(s) has been selected for observation of the said task, the procedure of JSA shall be discussed with the said employee, performing the job.
  • Preferably, the job safety analysis team should take field round of the area, where the job is actually to be performed.
  • Employees of other working area, who have performed the same task / job, should also be consulted for cross checking of the action steps associated with the Job / task.
  • All the outcome of the analysis should be documented in the prescribed format for Job Safety Analysis.

Stages involved in JOB SAFETY ANALYSIS (JSA)

Stage I: Select the Job for JSA.

Stage II: Accident history should be referred, if available. Review the worksite’s history of accidents/ near-misses etc. with the employees or past records. These events are indicators that the existing hazard controls (if any) may not be adequate and deserve more scrutiny.

Stage III: Write sequential procedure/Steps involved in performing a specific job.

Stage– IV: Assessment of potential safety and health hazards associated with each step.[Hazard Analysis]

Stage–V: The recommendation/identification of action(s) / procedures(s) against each step that will eliminate or reduce the risk of a workplace with respect to injury or illness, property, and environment.

Stage VI: JSA review and sign by HOD of operation department and HOD of concerned Maintenance Department

Stage VII: Checking compliance status at the site

Steps and Activities
