Near miss and accident ??
Are you sure you know the difference between

Let us first agree;
it is your company's policy that determines this point] But know the right thing In short, a factor working on a height - whatever the level (above or at ground level) - and occurred without any signs of any apparent injuries, is this calculated / recorded
! The definitions of any reference to safety, such as , and for this part, are almost all the same, (resulting in injury / damage),
loss - not imminent - (almost resulting in injury / damage) !! With experience, we still know what
mean? The previous example, the worker fell and did not show any signs of any need - no injury - it remains for sure that this classification is an imminent accident, where is the problem left 😒? The problem is that you don't really know if there was harm or not!! Damage or injury is not a condition that appears on time, on the contrary, it can appear an hour after the occurrence of the event or after two hours or after 24 hours normal!! How come this talk? The factor when the occurred in his body increased, which reduced the feeling of the effect of

impact, even if it shows no signs of visible injuries, is considered damage/injury ... Thus the previous case is classified as an accident. When do I consider it an imminent accident? It was about to happen, but it didn't happen 😅, but the incident doesn't have the word "was" in its dictionary - even if ostensibly the man is healthy and 🌹 healthy __________________ People who studied
IG1 said what?? The only thing that separates accidents from imminent accidents is the outcome of this event... And take it from me; the impact is a damage whose severity varies according to the event
🔥 Reflecting on Lessons
Learned from a Major Accident-Ammonia Plant Syngas compressor oil tank
explosion 🔥
ACCIDENT DESCRIPTION 💥
On the 24th of April 2017, at 2:43 am, a trip occurred in an ammonia plant due
to an external power supply fluctuation. The dip lasted 0.4 seconds. This
fluctuation caused an automatic shutdown of the plant, and a normal shutdown
operation was performed. Flammable content flared off. After stabilizing the
process, the production shift was preparing the plant for restart. Everything
seemed normal, restart procedures were followed, but at 03:15, an explosion
occurred, followed by an intense oil fire in the compressor hall. Two operators
were present and evacuated without physical injuries. Internal and external
fire services arrived shortly after, and 45 minutes later, the fire was
extinguished. They could see that the main syngas oil tank (lubricant oil) had
"torn," and the fire could be localized to this tank. Immediate
consequences on people were limited to psychological impact (one employee on
long sick leave). In terms of the environment, there was a limited oil release
into the fjord that was rapidly addressed. Extensive damage was observed in the
electrical/instrumentation systems and in the compressor hall.
SUBSTANCE INVOLVED DESCRIPTION
The vapor phase of the oil tank normally contains a mixture of lube oil vapor
and syngas released by the seal oil circuit. Gas analysis has been conducted on
a similar system, and it was observed that the Hydrogen concentration ranged
between 0.1 to 2%. The quantity is difficult to estimate.
CAUSES DESCRIPTION
The root cause lay in an uncontrolled Management Of Change (MOC) affecting the
air separation unit trip system that allowed enriched air to be sent into the
nitrogen grid. The nitrogen grid was supposed to be a safety barrier in the
syngas compressor oil tank explosion scenario. A low suction pressure trip had
been removed some years back (2011) but was still mentioned in both P&ID
and standard operating procedures. Contributing factors included a lack of Process
Hazard Analysis that generated inadequate standard operating procedures and
inadequate training. There was also a lack of a proper alarm management program
and a poor human-machine interface.
EMERGENCY RESPONSE 🚒
Emergency response teams acted swiftly and effectively. The on-site water mist
system played a crucial role, although a minor issue with foam leakage arose
due to an open door.
LESSONS LEARNT 📚
This incident underscores the critical need for robust safety measures:
1. Management Of Change (MOC)
2. Process Hazard Analysis
3. Training
4. Alarm Management:
5. Human-Machine Interface
he Factories Act, 1948 is an
important piece of labor legislation in India that aims to regulate and ensure
the safety, health, and welfare of workers employed in factories. The Act
applies to factories engaged in various industries and manufacturing processes.
It provides guidelines for the working conditions, hours of work, leave, health
and safety measures, and other aspects related to the well-being of factory
workers.
