Familiarize yourself with Hydrogen as a substance

1. Hydrogen is a toxic substance that should be avoided at all costs.
2. Hydrogen is given certain European threshold values that limit the time being in contact with hydrogen.
3. Hydrogen leakage is easy to detect with organoleptic evaluation measures.

Familiarize yourself with hydrogen legislation and standards. A good overview is given in this document by the European Hydrogen Safety Panel and then answer the below questions YES or NO.

1. There are uniform global regulations dedicated to the safe design, testing, construction, and deployment of fuel cell and hydrogen technologies and systems.
2. ATEX directives can be applied to hydrogen even if hydrogen is not mentioned in the text.
3. Standards are useful instruments for organizations. They are not always mandatory to be applied unless otherwise stated in the regulation.

Accident, incident, and near-miss analyses can provide valuable information for preventive actions. For instance, an (analysis on HIAD 2.0 database) provides essential information on accident analyses

1. Accident investigation provides information on how to prevent similar kinds of accidents in the future.
2. From the safety management perspective, minor events like near-misses seldom provide valuable information for accident prevention.

Incidents and accidents related to hydrogen usage are mainly related to industrial contexts.
