Confined space fatality

One person died when entry was made into a decommissioned submarine without proper atmospheric monitoring. Most probable cause of the accident was oxygen depletion due to rusting inside the decommissioned sub. Many times, we feel that a decommissioned equipment is safer than an equipment that is in service. We let our guard down and then a fatality occurs. Sometimes, new equipment are brought to the site before a turnaround and placed near the unit. They may be nitrogen blanketed and have to be treated just like any vessel in service. Make sure your maintenance personnel understand this.

The importance of containment

An incident is being reported in the US where a storage tank storing Crude MCHM, consisting mostly of 4-methylcyclohexane methanol developed a hole and started leaking. The secondary containment (dykes) also failed and the chemical entered a river which is the main source of drinking water. 
Maintain your primary and secondary containments.....read about the incident in this link.

Online leak sealing incident

An incident in a refinery in Belgium in which a bonnet of a steam valve flew open killing two contractors during sealant injection highlights the dangers. Many engineers take on line leak sealing for granted and a quick fix to arrest leaks. Remember on line leak sealing is an inherently unsafe method unless properly engineered. In India a plethora of on line leak sealing agencies have mushroomed offering leak sealing at low cost. Cost should not be the deciding factor while choosing the agency. Check their engineering expertise.
