Cathodic protection systems must be maintained

An incident of a full bore rupture of an oxygen transmission pipeline occurred in France. Prior to the rupture there were no indications of any leak
The investigation determined that the rupture was caused by the presence of an extended thinning zone of the pipe due to external corrosion. This corrosion was due to:

• The pipe was immersed under the groundwater table during a part of the year. Groundwater brings dissolved oxygen.
• Coating was disbanded, thus cathodic protection was inefficient in this zone (shielding effect).
• The groundwater was renewed by thermal convection in the disbanded area through coating faults, with draining of corrosion products. Thermal convection was due to temperature difference between soil and gas just after compressor discharge

CO2 can kill - Dont underestimate it

An accident occurred in a building where dry ice was produced and involved a CO2 storage tank.
A hissing noise was coming from the valve of a tank . This was a leak resulting from the power being switched off days earlier. The power switch off also unfortunately cut the power to the CO2 indicator in the room. A security guard who came to investigate the hissing noise,  died after exposure to high CO2 concentration.

Beware of CO!

On November 7, 2007 a Pipeline X-Ray Inspection Technician was fatally overexposed to carbon monoxide levels while he was working in a pick-up truck, bed mounted camper shell-type dark room. The deceased had been working earlier the same day x-raying pipe welds and developing the film on a large pipeline project. At the time of the incident, the employee was working inside of the dark room developing a series of x-ray films that had been taken earlier in the morning on the same day. The deceased was an experienced technician in the industrial x-ray field with many years of experience.
Significant Factors:
•Employee was working in a dark room mounted in the bed of a pick-up truck, developing x-ray film, when he was overcome by carbon monoxide gas.
•The investigation was able to determine that the source of the carbon monoxide was a gas powered portable generator that was being used to power the small camper-shell type truck mounted dark room. Air sample testing revealed that the levels of carbon monoxide exceeded 500 ppm when working conditions were re-created by investigators. Another contributing factor was the weather conditions, specifically the wind direction in regards to the location of the working location. The dark room was located down wind from the placement of the portable generator, on the truck tailgate. The wind speed on the date of the accident was estimated to be 25-40 mph.
Recommendations:
•Brief all employees on the facts and circumstances of this fatal mishap.
•Brief/retrain all employees on the danger of working around equipment that produce carbon monoxide.
•Require that all portable gas generators that produce carbon monoxide gas to be located a minimum distance of five feet from structures having combustible walls and/or other combustible material. Keep exhaust gas from entering an area through windows, door ventilation intakes or other openings. Remind employees to note the wind direction and always maintain good ventilation by keeping carbon monoxide producing equipment down wind from the working area.
•Install carbon monoxide alarms in the camper shell-type dark rooms.

Is your forklift properly rated for use in hazardous areas?

At 4:30 p.m. on August 7, 2018, Employee #1 was scooping up the waste from the tank that was on the floor and placing it into the trash can. Employee #2 was driving the forklift to bring in more containers of chemicals. Employee #3 was walking in the warehouse area. Employee #2 was driving a forklift that was not rated to be used in an area that had Class 1, Division 1 flammable chemicals. The employee was bringing additional containers of chemicals in to the mixing room. When he parked the forklift, the vapors that were present in the drain reacted with the hot engine parts and were ignited. Employee #1 received 3rd degree burns on multiple parts of body, which later resulted in death. Employee #2 was hospitalized.

Thermal Runaway of battery

The Boeing 777 was en route from Amsterdam Airport Schiphol to Kuala Lumpur International Airport in Malaysia. En route, above the Andaman Sea, to the west of continental Southeast Asia, a sleeping passenger in a business class seat dropped his mobile telephone. When the passenger woke up, and placed the seat in the upright position, the telephone shattered. This caused overheating leading to what is known as thermal runaway of the lithium ion battery in the telephone. A considerable volume of smoke was released, which was concentrated in a small section of the cabin sealed off by curtains.
The captain decided to divert to Phuket International Airport in Thailand. The reason for this decision was the large volume of extinguishing water used and the possibility that the seat was still smouldering. The aircraft made a safe landing.
The airline in question is considering reviewing the protective equipment and the equipment available on board to fight fires caused by lithium-iron batteries. The airline is also investigating the effectiveness of existing passenger instructions for the adjustment of seats in relation to electronic devices that may end up trapped in the seat.

Are you identifying human factors in HAZOP studies?

On 6.9.19, at Amsterdam airport, a Boeing 737, aircraft was taxiing in a northerly direction on taxiway Charlie to runway 18C when it received take-off clearance for that runway. The flight crew then drove on taxiway Delta in a southerly direction and commenced the take-off. Air traffic control noticed this and instructed the crew to stop immediately. The crew aborted the take-off run and taxied back to the start of runway 18C, after which the aircraft took off uneventfully.
