Another pump accident
'On Monday, January 28, 2002, a clean coal filter drain pump exploded due
to steam build up within the pump, inflicting fatal injuries to the
fine coal operator at a preparation plant of an underground mine. The
victim was standing approximately 8 feet away at the on/off switch when
the pump cover struck him. The pump overheated after almost all liquids
had been pumped from the filter drain tank causing the remaining fines
to solidify, thus preventing flow. The inlet and discharge lines then
became clogged with coal fines causing the pump to become a closed
pressure vessel".Read about the accident in this link.

Incomaptibile chemicals cost you!
A radiation leak from a drum containing radioactive waste at an underground nuclear waste dump in New Mexico was caused by “chemically incompatible” contents, including cat litter, that reacted inside a barrel of waste and caused it to rupture. It is reported that cat litter containing silicates is purposely used as a stabilizing agent in nuclear storage for stabilizing radioactive nitrate salts. A scientist inadvertently used an organic brand of cat
litter which does not contain silicates. After some days, the nitrate salts in the barrel heated up, releasing hot gases, pressurised the drum and ruptured it.
The damage caused a radiation leak that will cost approx. USD 240 million to clean up!

This is not an April Fools day joke!!!!!

Access and Accidents
The German wings plane that crashed in the Alps on Tuesday killing all onboard is being attributed to the co pilot intentionally crashing the plane, when the pilot went out of the cockpit. The pilot was not able to regain access to the cockpit as the copilot is alleged to have locked the door from inside. There is an interesting video from popular science about how the cockpit door locking arrangement works.
Coming back to our industry, more and more electronic access systems are being installed in chemical plant control rooms and hazardous chemical storages to prevent unauthorized access. But have you thought about everything including emergency response or evacuation requirements in case of malfunction of these access control systems?
See the video about how the cockpit door locking arrangement works in this link.

Thermal expansion accident
Thermal expansion inside a valve caused the bonnet of the valve to fail. The safety alert mentions the following:
Pressure build-up occurs in the gate valve cavity from thermal expansion of fluids. Extreme pressure build-up from fluid expansion can occur if the valve body is completely full of fluids (e.g., a grease/oil/water mixture) and heated to elevated temperatures. Such pressure can exceed the rated working pressure of the valve.
A valve with the ability to isolate the body cavity from the flow line may be at risk.
Presence of grease or compounds designed to enhance sealing ability may exacerbate the condition.
Grease or a grease/oil/water mixture when heated in a sealed enclosure can exceed 7000 psi (48.5 MPa) at 250 °F (121 °C).
Gate valve body cavities that are not 100% full of fluids do not experience excessive pressure as the vessel was heated. Trapped air or gas allows room for thermal expansion.
