Safety Topic Incident: Fall From Height
Location of Incident: Venezuela
Brief Account of Incident
During an Acid job a Halliburton operator climbed to the top of a tank truck to check the fluid level in the tank. He leaned against handrail and the handrail failed causing him to fall to the ground approximately 3 meters. He suffered a sprained ankle.
Lesson Learned
1. Pre job equipment checklist should be thorough and should cover all safety equipment to protect personnel when working at height.
2. JSA (Job Safety Analysis) should cover all at risk tasks when working at heights.
3. Handrail design can be changed to make it more stable and fool proof.
4. Review and inspect all safety equipment when working at height with pre job checklist and JSA’s.

Hidden Hazard Accidents
Safety Lesson Learned: Hidden Hazard Accidents
Location of Incident : Office, Workshop or even House
Have you ever bumped into another person or ever been hit by falling or flying object? In 1979 a total of 1,883 lost time claims were filed with the Industrial Commission Of Ohio by Ohio hospital employees. Of these claims, 211 were for injuries that happened when people were struck by moving objects. Lost work days because of these accidents in 1979 numbered 5,472. A few precautions will reduce your chances of becoming one of these statistics.
A door is another moving object that often strikes people. Never stand in front of such a door for an extended period of time. We shouldn’t use a ladder where a door opens toward it unless you can be sure by locking the door or propping it open.
People too can be safely hazards if they do not watch where there are going if they don’t notice threats to his safety that are right in front of him. When approaching a corner there is another possibility to hazards where you cannot see or be seen by those traveling in other directions. Think about how this type of accident can be avoided. The next person you bump into could be carrying hot coffee or sharp objects.
These are some ‘Hidden Hazards’ example which discussed and summarized by team members. There are many more things to think of to avoid this type of accidents from happened.

Ethanol Released
Safety Lesson Learned : Ethanol Released
Location of Incident : Des Moines Terminal
A connector on ½’ flush line of the loading rack alcohol pump broke off, allowing alcohol to spray from the pump whenever trucks were loading. A driver who was preparing to deliver a load of denatured alcohol to the terminal discovered the leak. Approximately 6,800 gallons of alcohol were released. The spill was totally contained, and there were no injuries or fire.
Incident Causes
1. Corrosion caused the pump thrust bearing to fail, creating excessive vibration in the pump and associated piping.
2. The flush line piping was stretched during installation, putting excessive stress on the connections.
Lessons Learned
1. Additional training may be required to assist operators in detecting pump problems before a leak developed.
2. Regular maintenance of pumps is critical to avoid bearing of shaft problems.
3. Pumps must be installed properly and with piping that is capable of withstanding the pressure and stresses of operation.

High Pressure Jet Cleaning
Safety Lesson Learned : High Pressure Jet Cleaning
Location of Incident : BP Chemical, Pahang Malaysia
Brief Account of Incident
The incident occurred at about 3.22 p.m. on Tuesday 15th May 2001 during high pressure (HP) water jet cleaning inside rotary vacuum filter (RVF) B ,BM702B. The contractor worker was doing cleaning for final inspection. The equipment was being overhauled.
During cleaning, the worker who was working alone inside the restricted & confined working area suddenly slipped and sprayed his right foot with the 3000 psi HP water jet stream. The water jet passed through his rubber boot and cut his right big toe. He received a deep lacerated wound measuring about 3 cm long on the lateral side of his right big toe. 7 stitches were administered. On the following day after the incident, he returned to work on restricted to light duty work.
Critical Factors
1. Lack of knowledge and compliance to the plant safety regulation
2. Lack of appropriate PPE – using non-steel toe shoes and no metal leg protectors.
3. Restricted/confined cleaning working area.
4. Improper communication/decision making by staff and contract staff.
5. Slippery condition inside the RVF drum.

Plastic Plant Explosion
Safety Lesson Learned: Plastic Plant Explosion
Location of Incident : Malaysia
Brief Account of Incident
The incident occurred during a maintenance operation. Workers were unbolting a five foot cover plate from a process vessel when the explosion occurred. The vessel was used to collect process wastes during process start ups and shutdowns. Preliminary evidence indicated the vessel may have contained process material from aborted start up that continued to react generating pressurized steam. Workers were unaware of the accumulated pressure when they began unbolting the cover plate. The incident resulted in 3 death.

High Pressure Incident
Safety Lesson Learned : High Pressure Incident
Location of Incident : USA
Brief Account of Incident
Contract personnel were installing a 3” flow line from a high pressure gas well to a compressor. Two roustabout crew, a backhoe operator and lease operator were present onsite. The flow line installation went uneventfully until the tie in to the compressor header. The flow line was laid in to the header, and a 90% connection was attached to the pipeline. The roustabouts began to thread the 3” pipe to make the connection. One employee went to the header and began to remove the victaulic clamp and blind so that the pipe line could be connected. He heard pressure, but assumed it would bleed off safely. He assured that his body position was not in front of the clamp and blind, and continued to release the bolts on the clamp one thread at a time, alternating between the left and right. Soon, the pressure inside the header trapped between the two valve caused the blind to exit the clamp forcefully, breaking two of the employees fingers and narrowly missing members of the roustabout crew who were in the line of fire.
