Single- and Dual-Wire Monitors--Which Performs Better Under the Big TopHave you ever compared electronics assembly to tightrope walking? While some days you may feel as though you’ve joined the circus, the common denominator here is—or should be—the beloved safety net. Without it, one misstep and your tightrope performance may fall flat.

What about in the workplace? What happens if an operator’s wrist strap malfunctions? Will your single-wire monitor catch you? With the dual-wire continuous monitor, even if one conductor is severed, you can always fall back on a reliable path-to-ground with the other one.

Single-wire continuous monitors, also known as impedance monitors, are also easily fooled. Great for your tightrope-turned-magic act, but not so great for safeguarding sensitive components. Single-wire monitors send a signal down the wire to the wrist strap expecting to find a mass (a person) at the end of the coil; they cannot determine if a person is actually electrically connected.

Dual-wire continuous monitors or resistance monitors, on the other hand, measure the resistance of the wrist strap in combination with the person, and signal an alarm if the product exceeds preset levels.

For the performance of a lifetime, shop All-Spec. We carry a broad selection of foolproof, dual-wire continuous monitors, so you can rest assured a reliable path-to-ground in just about every situation.

10 Quick Tips for Tackling Cleanroom Wet SpillsWet spills are often embarrassing. Lingering mystery smudges? They’re just plain tacky. Depending on your environment, these are the least of your concerns.

Chemical spills in your cleanroom can be costly and dangerous. Consider the following guidelines for wiping contaminants and spills quickly, effectively and safely:

  1. Always identify spilled liquids as soon as possible.
  2. Follow the liquid’s Material Safety Data Sheet (MSDS).
  3. Select durable wipers for the task at hand.
  4. Select gloves that will not deteriorate with use.
  5. For hazardous spills, wear two pairs of gloves.
  6. If possible, keep gloves dry during cleanup of hazardous spills.
  7. Wear all essential protective gear during cleanup of hazardous spills.
  8. Use dry wipers to absorb liquid immediately.
  9. Clean all affected surfaces according to your site’s protocols.
  10. Dispose of wipers according to your site’s established procedures.

Don’t be caught unawares. Comply with your facility’s SOPs, and stock plenty of cleaning and protective supplies in case of minor or major chemical spills in your cleanroom. With All-Spec’s selection of wipers, gloves and other PPE garments, you’ll make quick work of all of your cleanroom spills. As for those other wet spills? Can we recommend a good drycleaner?

5 Steps to Combat Cleanroom Static

by Kathy S. on July 24, 2015

5 Steps to Combat Cleanroom StaticIt’s no secret your low humidity cleanroom is ideal for keeping it clean, but did you know it’s ideal for creating static charge? Wiping down objects before they enter proves staticy, too.

Why should you control ESD in your cleanroom? Static charge causes microcontamination, physical damage and interference with automation systems, all of which can interfere with your bottom line.

Consider budgeting for “unforeseen” issues and follow these five steps to corral your cleanroom static:

  1. Ground electrical conductors wherever possible.
  2. Avoid the use of insulators whenever possible.
  3. Opt for dissipative materials, and remember to ground them.
  4. Use an air ionizer to neutralize static on nonconductors.
  5. Establish a comprehensive ESD control program that includes all of the above.

All-Spec stocks a large selection of personal grounding and ionization equipment for your unique cleanroom environment, so you can quickly and easily implement a program that dissipates static and not your profit.
