The boat was a 6.5 m semi-rigid electric-powered inflatable canoe, mainly used for greeting and directing pleasure boaters in harbour.It exploded without a flame shortly when an employee of the harbour master's office turned on the ignition after unplugging the batteries. The back of the boat was projected into the air, together with the employee, which was hospitalised. The boat was completely destroyed. Purchased three months before, this boat was one of the three pre-series prototype boats in service in marinas.

An empty 100-m reservoir of sulfuric acid (H2SO4) exploded at 9:15 am at a chemical site. Installed directly above its retention basin at a height of several metres, this reservoir was projected and fell nearby, toppling the scaffolding set up for reservoir maintenance and causing 3 workers (2 subcontracted personnel) to fall. Two of the three were seriously hurt. The internal emergency plan was activated, bringing both internal and external responders to the site. The injured were taken to hospital. The operator notified the Prefecture, local city halls and the general public.

An explosion occurred around noon while conducting hot work (with a disc saw) on a 320-m fixed-roof tank at a pharmaceutical plant employing 240 personnel. The tank belongs to a waste treatment unit as part of an antibiotic production process. The tank cover was blasted 20 m away and the subcontractor performing cutting works was killed. Three other subcontractors and a plant employee were severely burnt and injured by the shock wave. Notified by neighbours and not by the operator, fire fighters arrived on the scene 15 min after the explosion and promptly extinguished the fire.

A hydrogen explosion caused burns contaminated with radioactive dust to a member of the plant's maintenance crew. Three other workers escaped injury.The accident occurred in the basement of the plants turbine building during work on an out-of-service recombiner (an equipment that combines hydrogen and oxygen to make water. A review team has found that a leak in a valve on the system allowed the hydrogen gas to build up in the pipe where the employee was working with a grinding wheel.

An isomerization unit of a refinery was affected. The release was caused by the mechanical failure of one of the two compressors working in parallel at a pressure of 20 bars, conveying the gas mixture needed for the isomerization process. The jet fire was the consequence of the release and ignition of a gas mixture containing hydrogen. The jet fire headed towards the adjacent benzene saturation section hitting the nearest equipment (a pressure vessel) located 14 m from the release point.

The incident took place in a calcium powdered wire manufactory of "Chepetsk Mechanical Plant". Some amount of water find it's way in a container where the mixing of different powders took place. As a result of chemical reaction active evolution of hydrogen occurs which results in accidental explosion from a spark. The explosion caused 5 injuries and 4 fatalities.
