Hazards of aerosol cans

 "Two electricians suffered singeing burns when residue in an electrical switchgear cubicle was ignited shortly after an electrical contact cleaner aerosol had been used. In another case  solvent from a pressure can was ignited by a heat gun. A safety risk exists where any aerosol container with flammable contents is used in a confined space or near an ignition source, whether this is electrical switchgear or some other source of raised temperature.
As they are used so frequently, it is important to refer to information on the can itself or preferably to the appropriate material safety data sheet regarding the flammability of the contents or any other restrictions on usage. Some material safety data sheets state that the aerosol container must not be used in confined spaces or may burst if exposed to temperatures exceeding 50°C.Incorrectly used or stored aerosol containers may represent a safety risk. It is important that material safety data sheets are available" Courtesy Queensland Government - department of mines

Common sense is not so common

 I was chatting with a Plant Manager recently when he lamented the fact that his operators believed the instrumentation rather than common sense. A pump was not delivering the required flow, even though the current drawn by the motor was normal. The operators checked the position of the recirculation control valve in the DCS and it indicated close. They then requested maintenance to replace the pump twice but the problem remained. Finally they found out that the recirculation valve was open in the field though it was indicating close in the DCS.
I see similar things happen in complicated PSM systems where poeple loose sight of what is the objective of PSM. PSM is common sense applied to keep the hazardous chemicals where they belong.

Maintaining old assets

An interesting article has been published in Offshore Engineer, titled "Tackling the backlog".
It talks about how many assets in the UK oil exploration industry is more than 25 years old and  that critical maintenance backlogs have been going up since 2010. It mentions "Safety critical maintenance backlog has increased from just above 700 man hours per installation to more than 4000, as at Q3-4 2014, with the increase having started from 2010, and the greatest rises in 2013 and 2014. Meanwhile, unplanned losses account for the greatest increase in the lost production efficiency, with planned shutdown time also increasing” . The article is worth a read. Please google "Offshore Engineer Tackling the backlog"

Human error by a Pilot

On 08.08.2014, an Indian commercial passenger jet was involved in loss of altitude incident during cruise over Turkish Airspace. The incident occurred after the aircraft had flown for 04 hours 43 minutes from Mumbai. The aircraft was flying on westerly track which was between 230 and 300 degrees and was flying on auto pilot at a height of 32000 feet. The Pilot in command was undergoing controlled rest as per statutory requirements and the controls were with the First Officer.

The First Officer, while updating the direction heading 292 degree, instead turned the altitude knob to 292 FL (29000 feet) and pressed thereby causing the aircraft to descend as the auto pilot obeyed the order to descend to 29000 feet. The Turkish Air Traffic Controller noticed the aircraft descent and called through radio about the unauthorized descent. Subsequently, the First Officer pressed ALT HOLD and climbed back to FL320 (32000 feet). The First Officer then woke up the Captain who was undergoing controlled rest and informed him of the incident. (Source: DGCA incident report).

In our industry, there have been numerous incidents where wrong setpoints or outputs have been entered by the DCS operator, leading to plant upsets. Do you consider this in HAZOP's?
