The self-closing doors are commonly fitted with a chain and fusible link that can be used to safely hold the doors open while moving bottles in and out, but I have been amazed at how many folks don't realize that it's there and what it's for. The self-closing doors are essentially the same principle as a spring return valve for flammable dispensing, i.e., if there is a spill or fire during movement of materials, then the cabinet will get isolated (with the intent in a fire scenario that the rest of the material in the cabinet does not become part of the fire and/or that the fire is inside the cabinet gets starved of air). As for the self-closing requirement, look at your locally applicable fire code or check with your "Authority Having Jurisdiction" -- in California, the 2007 Fire Code requires self-closing doors at section 3404.3.2.1.3. And it has been very controversial just as we have seen in this forum's exchange!

People find it inconvenient to hold the spring-loaded doors open to the flammable cabinet while placing or retrieving gallon sized bottles of liquids - especially since the bottom of the door is slightly higher than you can hold with your foot. Lots of work-arounds were discussed. At this point all I can add to the discussion is that MaryAnn's not the only one who's noticed that unintended negative consequence resulting from a safety regulation.

In trying to keep the door open, or not realizing how close the door is people have bumped the door pulling out the chemical and dropped the bottle. Our older cabinets are not self closing and we don't have a problem with the doors being left open. I prefer those that are not self closing.

For example, it is my understanding that California requires self-closing doors. The major US manufacturers sell both manual and automatic door models, so there is obviously no federal requirement. Given the obvious safety advantages of automatic door closers, the question should be why one would wish to defeat a safety feature that is, at best, a trivial annoyance. I strongly endorse their use whenever feasible.
