Yes. EPA’s Risk Management Program requires a pre-startup review under 40 CFR 68.77 for covered Program 3 stationary sources.Continue Reading

A PSSR should be completed before highly hazardous chemicals are introduced into a new or significantly modified covered process. Under EPA’s Program 3 prevention program, a parallel pre-startup review is required before regulated substances are introduced.Continue Reading

MOC controls the change. PSSR confirms the changed or new process is ready for safe startup. OSHA enforcement guidance treats them as separate PSM elements.Continue Reading

A strong PSSR checklist includes design verification, current procedures, safeguard readiness, closure of hazard-review actions, completed operator training, and documented startup approval. OSHA’s required confirmation points are design conformance, adequate procedures, resolved or implemented PHA recommendations for new facilities, and completed employee training.Continue Reading

Yes. OSHA requires a PSSR under 29 CFR 1910.119(i) for new covered processes and for modified covered processes when the modification is significant enough to require a change in process safety information.Continue Reading

Avoid flames or electrical sparks. Evacuate the area immediately. Notify emergency responders and hydrogen safety personnel.Continue Reading

Notable hydrogen-related accidents include the Hindenburg disaster (1937), and the 2019 Norway hydrogen station explosion.Continue Reading

Always store and handle hydrogen in well-ventilated areas, avoid open flames or sparks, use proper leak detection systems, and follow safety regulations to prevent fire or explosion risks.Continue Reading

Hydrogen gas is generally non-toxic and safe to inhale in small amounts, but prolonged exposure in confined spaces can lead to asphyxiation by displacing oxygen.Continue Reading

Hydrogen is highly flammable, easily ignitable, can cause explosions when mixed with air, is colourless and odourless (making leaks hard to detect), and can displace oxygen in confined spaces, leading to asphyxiation.Continue Reading
