This ebook raises operators' expertise, in the chemical and strategy industries, to the dangers of nitrogen and capability dangers of utilizing catalysts. It starts off by way of describing nitrogen and using catalysts, its makes use of and houses, sooner than mentioning the capability risks. utilizing case reviews of tangible injuries to focus on the capability threats and clarify the potential reasons, it increases the information and wisdom of operators to the hazards of nitrogen and of utilizing catalysts, permitting them to identify risks prior to injuries happen. The publication concludes with a self-test part permitting readers to check their realizing of the data offered. this can be a very good advent to the subject for college kids.

Lethal human exposures have been estimated as 30 ppm for 30 minutes inhalation, and 50 to 500 mg/kg if ingested. Initial symptoms include headache, dizziness, nausea and vomiting, which disappear when exposure ends. Vapour also irritates the eyes, nose and throat. ’ It is also a suspected carcinogen (cancer-causing agent). Carry out an occupational health risk assessment before undertaking any work associated with the handling of catalysts. 6 Crushing hazards When digging through catalyst, specialist contractors must take care that no high ‘wall’ of catalyst is left in place, ready to cave in if disturbed.

ACCIDENT Two men were found dead inside the CO converter in an ammonia plant during the removal of catalyst from the converter under nitrogen cover. One operator was working inside the CO converter which was under a nitrogen blanket wearing conventional compressed air breathing apparatus; the air was supplied from bottles situated outside the vessel.
This equipment and the expertise that goes with it is only available from outside specialist contractors. 12 Catalyst specialist contractors for inert gas/nitrogen reactors Management must thoroughly scrutinize the management systems and associated procedures employed by inert gas ‘specialist’ contractors prior to the award of contract. In view of the restricted space inside reactors and the limited time available to save an ‘unprotected’ operative inside an nitrogen atmosphere, ‘specialist’ contractors must prove that they have the required back-up respiratory and other emergency/rescue equipment to handle the range of potential failures.
