Seems like a cleanroom is no place for a ladder: a dirty, dusty, paint-smeared structure used by the contractor who does the termite repair on your house. But in fact, cleanrooms are perfectly-suited to ladders, if they are Terra’s BioSafe brand. Cleanroom and lab ladders are used to access out-of-reach filters, lighting, or equipment. For example, taking particle measurements and airflow readings below the filter face in preparation for an ISO inspection may require a ladder. And what about changing light bulbs and making small repairs? Terra’s shelf platform can be attached to ladders, providing a convenient surface for tools and small instruments.
生物防护折叠室梯子具有许多独特的功能，使其非常适合无菌环境。
Ultra-Clean Electropolished Steel
BioSafe ladders are manufactured from 304 stainless steel that has gone through a purifying electropolishing treatment. First, all seams are welded and the steel is mechanically buffed to smooth-out burrs and crevices. The steel is then immersed in an electrified chemical bath which removes surface impurities, resulting in metal with a nickel- and chromium-rich surface that forms a protective layer. Traces of corrosion-prone iron are removed, as well as fine directional lines common with mechanical finishing. The ultra-smooth finish is easier to clean; wipes won’t snag.
OSHA安全标准
符合OSHA的梯子，带有扶手和可折叠的架子。
Terra’s ladders also meet OSHA Part 1926-1053 safety requirements. Medium-duty ladders are Type II with a 225-pound rating, and special-duty ladders are Type IAA for loads up to 375 pounds. Rungs have raised cut-outs that help maintain firm footing while stepping up and down. These cut-outs also reduce overall surface area where particles can accumulate. Non-slip polyurethane leveling feet ensure that the ladder will stay securely in place while you complete your service tasks. Some ladders are also designed with handrails to help maintain balance.
存储和运输
Fold the ladders to store them away from work-in-progress areas. They can be collapsed and hung on walls with hooks, or placed in out-of-the-way locations away from foot traffic. Steel can be heavy to lift and move, so wheels are built into every ladder: simply fold the ladder, tilt it, and roll it like a suitcase to the desired location. When it’s unfolded in place, the non-slip feet make sure the ladder doesn’t move.
Shelf extender adds height and work surface to hold tools or supplies
Removable Work Surface
The optional shelf extension holds a tool chest, meters and gauges, hardware components and other supplies used in cleanroom service and monitoring tasks. The removable shelf hooks to brackets on the top of ladders, and folds down flat when the ladder is placed in storage. It is also made of ultra-clean electropolished 304 stainless steel.
