The CSB issues safety recommendations to prevent the recurrence or reduce the likelihood or consequences of similar incidents or hazards in the future. Recommendations are issued to a variety of parties, including government entities, safety organizations, trade unions, trade associations, corporations, emergency response organizations, educational institutions, and public interest groups. Recommendations are published in CSB reports and are closed only by vote of the Board. The CSB tracks all recommendations and communicates regularly with recommendations recipients to ensure that the recommended corrective actions are implemented.

Update the Chemical Reactivity Hazards website (https://www.osha.gov/chemical-reactivity) to include various reactivity assessment tools developed since the 2002 Index-Based Method for Assessing Exothermic Runaway Risk and the 2004 Preliminary Screening Method. Mathematical methods, thermal analysis methods (e.g., Accelerating Rate Calorimeter (ARC) testing), ASTM E1231-19 Standard Practice for Calculation of Hazard Potential Figures of Merit for Thermally Unstable Materials, Stoessel Criticality, and the O.R.E.O.S. Method (an assessment that combines Oxygen balance calculations, the Rule of 6, and the Explosive functional group list with Onset decomposition and scale) are tools that could be considered for the update. The “Additional Resources” section of the website should also be evaluated for necessary changes and updates.

Amend the Process Safety Management (PSM) Standard, 29 CFR 1910.119, to achieve more comprehensive control of reactive hazards that could have catastrophic consequences.

  • Broaden the application to cover reactive hazards resulting from process-specific conditions and combinations of chemicals. Additionally, broaden coverage of hazards from self-reactive chemicals. In expanding PSM coverage, use objective criteria. Consider criteria such as the North American Industry Classification System (NAICS), a reactive hazard classification system (e.g., based on heat of reaction or hazardous gas evolution), incident history, or catastrophic potential.
  • In the compilation of process safety information, require that multiple sources of information be sufficiently consulted to understand and control potential reactive hazards. Useful sources include but are not limited to:

- Literature surveys (e.g., Bretherick’s Handbook of Reactive Chemical Hazards, Sax’s Dangerous Properties of Industrial Materials, CAS SciFinder).

- Information developed from computerized tools (e.g., ASTM’s CHETAH, CCPS’s Chemical Reactivity Worksheet).

- Chemical property data compiled in PubChem and the REACH (Registration, Evaluation, and Authorization of Chemicals) dossiers maintained by the European Chemicals Agency (ECHA).

- Chemical reactivity test data produced by employers or obtained from other sources following established standards such as:

- ASTM E537-20, Standard Test Method for Chemicals by Differential Scanning Calorimetry;

- ASTM E1981-22, Standard Guide for Assessing Thermal Stability of Materials by Methods of Accelerating Rate Calorimetry;

- ASTM E2550-21, Standard Test Method for Thermal Stability by Thermogravity; and

- ASTM E1231-19, Standard Practice for Calculation of Hazard Potential Figures of Merit for Thermally Unstable Materials.

- Relevant incident data from the plant, the corporation, industry, and government.

  • Augment the process hazard analysis (PHA) element to explicitly require an evaluation of reactive hazards. In revising this element, evaluate the need to consider relevant factors, such as:

- Rate and quantity of heat or gas generated.

- Maximum operating temperature to avoid a runaway reaction from decomposition.

- Time to Maximum Rate under Adiabatic Conditions (TMRad).

- Thermal stability of reactants, reaction mixtures, byproducts, waste streams, and products.

- Effect of variables such as charging rates, catalyst addition, and possible contaminants.

- Understanding the consequences of runaway reactions or hazardous gas evolution.

For existing facilities, establish a phase-in requirement for the replacement of wooden bins with bins made of noncombustible materials of construction within a reasonable time period (e.g., 3 to 5 years from the date standard revisions are enacted), based on feedback from the fertilizer industry.

ii. Require automatic fire sprinkler systems and fire detection systems for indoor FGAN storage areas.

iii. Define adequate ventilation for FGAN for indoor storage areas.
