What are the mandatory requirements for confined space entry:

Permit to Work (PTW): Must be issued before entry.
Risk Assessment: Identify hazards (toxic gases, oxygen levels, etc.).
Oxygen Levels: Should be between 19.5% and 23.5%.
Atmospheric Testing: Continuous monitoring for harmful gases.
Ventilation: Ensure proper airflow to remove harmful gases.
Isolation & LOTO: Isolate hazardous energy sources.
Rescue Plan: A rescue plan must be in place.
Supervisor: A competent supervisor oversees the entry.
Safety Equipment: Proper PPE (harness, respirators, etc.) required.
Communication: Continuous communication with the outside.
Entry & Exit Procedures: Clear procedures for safe entry/exit.
Time Limits: Restrict time spent inside the space.
Training: Workers must be trained in confined space entry.
Signage & Barricades: Clearly marked and barricaded areas to prevent unauthorized entry.
What is Zero energy? when is zero energy demonstration required?
Zero Energy:
Zero energy means completely isolating all potential energy sources (e.g., electrical,
mechanical, chemical) to ensure the work area is safe and free from hazards.
When is Zero Energy Demonstration Required?
Before work starts: To ensure no energy sources are active.
Before permit issuance: As part of the PTW process.
During permit revalidation: To confirm isolation remains effective.
For IDC-linked work: When equipment is isolated or de-energized.
Give 5 responsibilities of Permit Receiver to verify at site before starting job?
Verify Worksite Safety: Ensure the site is safe with proper barricades and signage.
Check Permit Conditions: Confirm the permit details match the job and safety measures.
Confirm Isolation: Ensure all hazardous energy sources are isolated and zero energy is
achieved.
Inspect Safety Equipment: Ensure necessary PPE and safety tools are available and in good
condition.
Review Communication/Emergency Procedures: Verify communication systems and
emergency plans are in place.
Explain 5 Live Saving Rules related to Permits and Associated Certificates?
Work Authorization: Work with a valid work permit when required.
Energy Isolation: Verify isolation and zero energy before work begins.
Confined Space: No confined space certificate no entry into confined space.
Verify gas tests are conducted as per permit.
By Passing Safety Controls: Obtain authorization before overriding any safety system.
Working at Height: Protect yourself against a fall when working at Height.
