- Keeping records of incidents on site.
- Investigating hazards and dangerous occurrences and conducting safety inspections.
Q: What is a Permit to Work (PTW) System?
A: The Permit to Work (PTW) system is a formal written procedure that uses a document to control work by identifying potential hazards and conducting risk assessments. It facilitates communication among supervisors, operation teams, maintenance teams, and contractors.
Q: Explain the Types of Work Permits in the Oil & Gas Industry.
- Hot Work Permit (Red): For work involving flames, sparks, or heat.
- Cold Work Permit (Green): For work that does not generate heat or sparks.
- Radiography Permit (Yellow): For work involving radiographic activities.
- Vehicle/Mobile Plant Entry Permit: For entry of vehicles or mobile plants into hazardous areas.
- Confined Space Entry Permit: For entry into spaces with limited access, not designed for continuous occupancy.
Q: What is Excavation and its Types?
A: Excavation is any man-made cut, cavity, trench, or depression formed by earth removal.
There are two types:
- Manual Excavation: Without using powered equipment.
- Mechanical Excavation: Using electrical or mechanical equipment.
Q: What are the Hazards Associated with Excavation?
- Soil collapse
- Risk from underground installations like pipelines and cables
- Drowning due to water seepage
- Vibration from nearby machinery
- Oxygen deficiency
- Accidental falls
- Dropped objects
- Fire and explosion
- Electrical shock
- Presence of explosive devices
Q: What are the Precautions for Safe Excavation?
- Obtain ground clearance if necessary.
- Maintain a safe distance from pipelines and cables.
- Use ladders for excavation deeper than 1 meter, with ladders placed every 7.5 meters.
- Place excavated material at least 1 meter from the edge.
- Keep heavy machinery away from the excavation edge.
- Use barriers and warning signs around trenches.
- Ensure emergency services access is not obstructed.
Q: What is Confined Space and What are its Hazards?
A: A confined space has limited entry and exit and is not designed for continuous occupancy.
Hazards include:
- Oxygen deficiency
- Flammable or toxic gases
- Poor illumination and ventilation
- High temperature and humidity
- Restricted movement
- Electrical and pressurized fluid hazards
Q: What is the Procedure for Entering a Confined Space?
- Obtain a permit ensuring complete isolation and cleaning of the space.
- Conduct gas tests to ensure no hazardous atmosphere.
- Conduct a pre-task meeting with all entrants.
- Assign a trained attendant at the entrance.
- Equip entrants with body harnesses and life lines.
- Use appropriate lighting and explosion-proof equipment.
- Keep a rescue team on standby if necessary.
- Barricade the area with warning signs.
Q: Explain Hydrogen Sulfide (H2S) and its Hazards.
A: H2S is a highly toxic, flammable gas produced by the decomposition of organic materials. It smells like rotten eggs at low concentrations and is undetectable at high concentrations. Exposure can cause irritation, dizziness, nausea, and can be fatal at high levels.
Q: What are the Safety Measures for H2S?
- Use escape masks in H2S-prone areas.
- Conduct immediate gas tests if H2S is suspected.
- Equip personnel with detectors and alarm devices.
- Evacuate to a designated assembly point if H2S is detected.
- Use breathing apparatus in contaminated areas.
- Post warning signs in H2S areas.
Q: Define TLV-TWA, STEL, and IDLH.
- TLV-TWA (Time Weighted Average): Average concentration over an 8-hour shift.
- STEL (Short Term Exposure Limit): Maximum concentration for a 15-minute period.
- IDLH (Immediately Dangerous to Life and Health): Minimum concentration that poses a threat to life and health.
