What is a Pre-Startup Safety Review (PSSR)?
Prepared and arranged by: Dr. Amin Padash, HSEQ Coach, President of the Iranian Scientific Association of Health, Safety and Environmental Management and Engineering (HSEME)
A PSSR is a systematic process performed before the startup of any new, modified, or repaired facility, equipment, or system to ensure operational safety and compliance. It acts as a final verification step, confirming that all elements—both physical (hardware) and procedural (training, documentation, safety systems)—are in place and functioning properly to prevent incidents.
PSSR is often mandated by industry standards, such as:
- OSHA's Process Safety Management (PSM) Standard (29 CFR 1910.119)
- API RP 75 for offshore drilling and production.
- ISO 45001 for occupational health and safety management.

Introduction to ESG (Environmental, Social, and Corporate Governance) and its importance (Part One)
What is ESG? Definition and general concept
ESG is an acronym for three words: Environmental, Social, and Corporate Governance. This concept refers to a set of criteria and principles that evaluate the performance of organizations in the field of sustainability, social responsibility, and management transparency. ESG helps companies improve their environmental impacts, social impacts, and management structures and move towards sustainable development.
These criteria cover a variety of topics, including reducing greenhouse gas emissions, promoting diversity and inclusion in the workplace, transparency in management decisions, and combating corruption. In short, ESG is a tool that allows companies to manage and evaluate their performance from a social and environmental responsibility perspective.

Problem-solving with the fishbone technique and the 6M and 5W methods
- Fishbone Diagram Overview
The Fishbone Diagram is a tool used to identify and analyze the root causes of a specific problem. It helps visualize how various factors contribute to the outcome. The diagram is structured like a fish, with a central spine representing the problem, and the "bones" representing multiple categories of causes.
In the context of problem-solving:
- Categories (bones) help break down complex issues.
- Root causes are identified by systematically analyzing different factors.
- 6M Method: Categories of Causes
The 6M is widespread in manufacturing and industrial environments but can also be adapted to other fields. These six categories help analyze the potential causes of a problem.
