Occupational and Process Safety Engineering

Upstream facilities must implement both Occupational Safety (personal-level) and Process Safety (system-level) measures to prevent incidents and minimize consequences. Key elements include:

Personal Protective Equipment (PPE)

  • Compliance with ANSI/ISEA Z87.1 (eye protection)

  • Z89.1 (head protection)

  • ASTM F1506 (FR clothing)

  • EN ISO 20345 (safety footwear)

Fall Protection and Work-at-Height (OSHA 1910.28/29)

  • Fall arrest systems, ladder safety training, and regular inspection of anchor points.

Permit-to-Work (PTW) Systems

  • Controls for hot work, confined space entry, working at height, Lock Out Tag Out (LOTO), electrical isolation, and simultaneous operations (SIMOPS).

Lockout/Tagout (LOTO)

  • Implementation of OSHA 1910.147, ensuring isolation of mechanical, hydraulic, pneumatic, and electrical energy sources.

Fire and Explosion Prevention

  • Use of intrinsically safe equipment, fire-resistant barriers, and fire detection/suppression systems per NFPA 72, API RP 2001, and IEC 60079 for explosive atmospheres.

Emergency Response Preparedness

  • On-site emergency response teams (ERT), muster drills, spill kits, firewater systems, and mutual aid agreements.

Well Control and Blowout Prevention

  • IWCF/IADC well control certification, regular BOP function tests, and compliance with API STD 53.
