Secondary Containment Trays — Controlling Damage by Containing Chemicals Before They can Escape

How do you control your chemicals when they leak? Few containers are truly leak proof, especially once they’re opened and you’re dispensing chemicals, so having a fall-back plan is a good idea. And secondary spill containment that is where supplementary containment trays can help.

So exactly what are supplementary containment trays?

Basically, they’re exactly what the name says: trays, i. e., flat containers, that have spills and water leaks as a supplementary barrier before they can escape and do damage.

Normally, you keep chemicals in their own containers. Those could trickle. However, where supplementary containment trays really shine are work areas where those chemicals are used for various purposes and perhaps combined with others. While being poured from container into another, they can easily leak.

But instead of running off the surface onto a floor, where they spread or are monitored by people stepping into any puddles they might form, they’re being within one place: in a supplementary containment tray.

Why supplementary and not primary?

Trays are not suitable as primary storage containers. For starters, they’re not closable, and in addition they themselves are highly leak prone. However, they’re great as a back-up. Since someone working with chemicals on a tray can see if there’s a leak, they can easily clean things up right as they happen, so a tray is perfectly sufficient for that purpose.

Also, if an open container on the tray should topple over, the tray will secure the liquid and allow it to be assimilated by suitable absorbents.

What types of absorbents should be used?

There are a number of options, but one of the easiest ones to go as well as one of the most cost-effective would be absorbent pads. They can be kept close by and can be quickly used to clean up any spills or water leaks before they can be a problem. Depending on your needs and the chemicals involved, you may also want to keep a suitable leak kit handy.

Are those trays really big enough to contain serious spills?

You should employ good judgment of course. Trays do have a capacity from 5 gallons up, depending on size. They’re perfect for smaller jobs.

If you have a more impressive job, you may want to use some of the larger pallets. Those are available in a range of sizes, and are suitable for storing of drums and other large containers. They are also available for dispensing units and can have a capacity all the way to 400 gallons, which will give you a great deal of protection.

High quality supplementary containment trays and larger pallets are made out of high solidity polyethylene and will be able to hold up to extensive use and a broad range of chemicals.
