Legal Requirement for PTW

5. OSHA
• It shall be the duty of every employer to
– Provide and maintain the plant and a
systems of work that are as far as practical,
safe and without risk to health.

6. Who Is Employer ?
• Employer means the principal employer
or the immediate employer or both.

7. Principal Employer
• Principal Employer
– Owner of business or process

decision has impact on the employees.

8. Immediate Employer
• A person representing the principal
employer in discharging his management
duties.
• The lowest level of management is the
supervisor
• Supervisors, superintendent, heads of
dept, managers, senior managers and
above are all immediate employers.

9. Supervisor As Employer
• A supervisor is an immediate employer as
he is directly responsible for the safety
and health of those who work under his
supervision.
• As far as is practical, the supervisor
makes sure that the plant and the system
of work are safe and without risks of
health to all his workers as well as others.

10. Safe Plant
• Equipment used for work
• Equipment where work is performed
• Area of a plant
• Unit of a plant
• Electrical equipment

11. Safe System of Work
• A system to ensure people work safely
– JSA
– PTW
– SOP
– LOTO
– Lift plan

– Tool box talk etc etc
• Safety and health for the people, the plant and
the environment are taken into consideration.

12. Safe Work Documents
• SOP
– This Safe Operating Procedure is established under the
company procedure for a specific activity that is carried
out on a regular basis. Requirements are clearly stated
for safe work.
• JSA
– This document is prepared and approved as a pre-
requisite to obtain a permit to work. It contains details
of job steps, their associated hazards as well as
corresponding control measures for each hazard, in
order to perform the work without any accident.

13. Company Procedure
• Company procedures should be an instruction
to meet regulations and legislations
