Chemical Reactivity Worksheet

The Chemical Reactivity Worksheet (CRW) is a free software program you can use to find out about the chemical reactivity of thousands of common hazardous chemicals, compatibility of absorbents, and suitability of materials of construction in chemical processes.

Golden Rules

CCPS Golden Rules are designed to arm process safety professionals with information to deal with process safety hazards. These rules / tenets are based on absolute statements to address the inherent hazards associated with process technologies including FCC operations, the chlorine chemistry, nitration chemistry, peroxides, combustible dust, and others.

Golden Rules

LOPA Data

Layer of Protection analysis (LOPA) is a simplified quantitative tool for analyzing and assessing risk. LOPA was developed by user organizations during the 1990s as a streamlined risk assessment tool, using conservative rules and order of magnitude estimates of frequency probability and consequence severity. This Database is a benefit for employees of CCPS member companies. Full access requires login.

Process Safety Incident Evaluation (PSIE) Tool 

The app for the updated Process Safety Incident Evaluation Tool has been released. The updates include changes to the threshold quantities and calculations to match the CCPS Process Safety Metrics Guide for Leading and Lagging Indicators, Ver 4.1 (“CCPS Metrics Guide”), and API RP 754, Process Safety Performance Indicators for the Refining and Petrochemical Industries, Ver 3.

Download the PSIE Tool at the Apple Store. (Coming soon on Google Play Store)

The PSIE app has three main features: 1) a Chemicals Database; 2) a Process Safety Incident Evaluation (PSIE) questionnaire, and 3) a Tier 1 Incident Severity Weighting calculation.

  1. The chemicals database contains a list of more than 2,000 chemicals. The database includes the chemical’s UN Code, its Hazard type, and its Tier 1 and Tier 2 Threshold Quantities for both outdoor and indoor releases. In addition, the user can add, edit, and remove custom chemicals or mixtures in the database.
  2. The Process Safety Incident Evaluation (PSIE) feature lets the user determine whether the incident is a Tier 1 or a Tier 2 release or not. The step-by-step questionnaire in the app is based on the decision tree published in the CCPS Metrics Guide.
  3. The Severity Weighting calculation feature lets the user determine the severity rating of a Tier 1 incident. This questionnaire is based on the criteria shown in Table 1 of the CCPS Metrics Guide.

Last but not least, the app enables users to save, e-mail, or print their final evaluation report afterward.

Process Safety Incident Database

The Center for Chemical Process Safety (CCPS) developed the Process Safety Incident Database to collect, track and share important process safety incidents and experiences among project participants.

Process Safety Metrics

Companies continuously improving their process safety performance must select, implement, and monitor company-specific process safety metrics for leading and lagging indicators. In 2021, CCPS member companies reviewed and updated the CCPS process safety metrics guidance. View the updated metrics guidance and other important metrics information in one place.

Process Safety Beacon

The Process Safety Beacon is a resource aimed at delivering process safety messages to plant operators and other manufacturing personnel. The monthly one-page newsletter covers the breadth of process safety topics.

Process Safety Beacon

Process Safety Moments

The purpose of these presentations is to use past incidents to raise the hazard awareness of the broader chemical industry, to bring more detail than the Process Safety Beacon alone can provide and to allow discussion of the potential hazards, controls and safeguards at your facility.

Process Safety Glossary

A glossary of process safety terms.

RBPS Resources Web Tool

This project aims to create a easily accessible web-based tool for each of the 20 Risk Based Process Safety elements. A central “hub” of free information of Process Safety information, tools, and resources. 

RBPS Web Tool 

Risk Analysis Screening Tool (RAST) and Chemical Hazard Engineering Fundamentals (CHEF) 

The RAST software and its associated CHEF documentation were developed through the collaborative efforts of volunteers from member companies of the Center for Chemical Process Safety (CCPS) and the European Process Safety Centre (EPSC). Special appreciation is extended to The Dow Chemical Company for donating RAST/CHEF for global use and for providing the resources to help modify the software and documentation such that companies can tailor the RAST software to meet their company-specific risk tolerance levels. It is sincerely hoped that companies using RAST and CHEF during their hazards evaluations and risks assessments will be able to improve their process safety performance.

Safe Work Practices (SWP)

Work place fatalities and injuries continue to occur with hot work incidents, nitrogen asphyxiations, confined space, line opening and other activities because of unsafe work practices. We need to make them more “human failure” resistant’.  This effort will likely save lives somewhere. This tool is designed to reach, and provide value to, a very broad audience including operations, maintenance and engineering personnel in the process industries (Chemical, petrochemical, electronics, natural gas and others). In addition to appealing to larger, more established member companies, this information has been tailored to also reach both large and small, domestic and international.

Vision 20/20

Vision 20/20, developed by the Center for Chemical Process Safety (CCPS), looks into the not-too-distant future to demonstrate what perfect process safety will look like when it is championed by industry; driven by five tenets of culture, standards, competency, management systems and lessons learned; and enhanced by community passion and four global societal themes.
