This is a starting list, not legal advice. What a building needs, and how often, depends on its use, size, risk category and equipment, and rules change. Check with your qualified people and current official sources.
What catches people out.
- Under DPR 462/01 the default earthing interval is 5 years, not 2. Two years applies only to building sites, medical rooms, higher fire risk and explosive atmospheres.
- A verifica periodica is done by a third-party body; a controllo periodico by your maintenance company. Track them separately.
- Since UNI 9994-1:2024, extinguisher checks are due by the end of the month.
