HEALTH HAZARDS

Some catalysts apart from being toxic are also suspected of containing carcinogens which should never be ingested or inhaled.

Dust emission as shown above is an all too common sight in catalyst handling. (See Dialog Technivac video 1 showing drum filling without dust control.)

Dialog Technivac’s latest development in total containment ‘Zero’ dust emission drum filling.

As a result of COSHH and similar legislation catalyst data sheets now contain detailed information which previously was non existent.

The data sheets for various catalysts now indicate that many of them are suspected of containing carcinogenic compounds which are a potential hazard during bed loading but after use in a process their toxicity level can be increased even further and they become even more of a hazard during unloading.

There is therefore only one goal in relation to addressing the problem and that can only be total containment.

DUST EMISSION AND GROUND SPILLS

What looks like steam in the photograph opposite is in fact catalyst dust particles escaping to atmosphere during open top drum filling.

Unfortunately this is an all too common sight during catalyst bed unloads and because the person carrying out the drum filling operation has difficulty in seeing what is going on, ground spillage is also a common feature. Whilst the drum filling operator needs personal protection equipment what is often overlooked is the real hazard to innocent passers by.

COMPLETELY ELIMINATING THE PROBLEM

Dialog Technivac as a result of in-house innovation actually solved the problem of dust emission and ground spillage during bed unloading as early as 1987.

Since 1987 Dialog Technivac’s original drum filler has gone through several design changes and the latest version shown opposite also eliminates the man handling of drums during palletisation and all versions provide total containment.

The same total containment principles also apply to Dialog Technivac’s flexible IBC filling equipment.

Such is the containment efficiency of Dialog Technivac drum fillers that although our operators are provided with dust masks and disposable coveralls as a precautionary measure in practice they are not really necessary.
