New Bill Defining Mold Signed in California

New bill defining mold signed in California

By Nicole Tormey

Mold sampling may see an increase in California due to a new law adding conditions to the definition of substandard housing. Senate Bill No. 655, which amends Sections 17920 and 17920.3 of the Health and Safety Code, adds mold as part of enforceable substandard conditions in California housing law.

Mold is now defined as “microscopic organisms or fungi that can grow in damp conditions in the interior of a building.” Health and code enforcement officers can now cite visible mold growth as a type of inadequate sanitation and thus substandard, as defined by the bill. Exceptions include minor mold and mold found on surfaces that can accumulate moisture as part of their proper and intended uses such as mold in a shower.  

By expanding the definition of a mold crime, the bill imposes a state-mandated local program requiring that code enforcement officers be trained in mold inspection practices. These officers have the authority to address mold complaints and require that mold be removed and sources of the moisture be remediated.  

Through our West Coast office in Irvine, CA, we provide a full range of air sampling and analysis services including comprehensive mold testing. As questions arise on the new California mold law, call us at 888-432-5227, email clientservices@galsonlabs.comor use our IH Live Chat, now available on tablets and mobile phones. We’ll be pleased to help in any way we can.

SGS Galson Laboratories’ FreePumpLoan™ program puts quality air sampling pumps at your disposal easily, quickly and, of course, free. To optimize the experience, we provide instructions with each pump and have an excellent client service team available 24/7/365 to help resolve any problems. If you are using the pumps, no doubt, you are technically savvy; and because time is money, we thought it would be useful to provide a reminder of the most common problems that can be easily diagnosed and fixed by you in the field on the GilAIr and AirCheck 52 pumps. 

If you experience a fault while sampling and the pump shuts itself off, denote the time

the pump has run from the LCD, found  on the side of GilAir pump or top of the AirCheck 2 pump. Address the fault cause with the troubleshooting instructions below and restart sampling.

The Aircheck 52 and GilAir have some common troubleshooting issues, and some are different, which we indicate below. For both air pumps, two basic faults can occur:

●     Air flow being restricted or cut off. The AirCheck 52 will show a broken arrow on the LCD display next to the timer indicating a flow fault.


●     An insufficiently charged battery.

When troubleshooting a flow fault, look for these issues, with reasonably easy fixes:

1.    When you encounter kinked or restricted tubing, re-route tubing to ensure unrestricted flow. Using an SGS Galson Personal Exposure Vest with built in tubing channels can eliminate this issue completely!

2.    When your pump inlet filter is clogged or dirty, the filter can be cleaned manually with tap water. If a new filter is needed:

o     On the Aircheck 52 pump, replace the filter with the spare filter provided in your pack.

o     On the GilAir pump, return to SGS Galson Laboratories for service.

3.    When the pump hose connector is loose on the AirCheck 52 -- the hose connector may occasionally loosen in transit -- make sure that the hose connector is hand tight.

4.    When the hose connector gasket is worn or missing or the hose connector is cracked or broken -- the SKC hose connector will occasionally break or become cracked if handled roughly during shipping -- check the hose connector and replace the pump hose connector and gasket with the spare ones provided in your pack, if necessary.

5.    When media is overloaded, replace the media. If additional media is not available it is best to end the sampling with the air volume collected or contact SGS Galson for additional media.

Battery fault

On the Aircheck 52 pump a battery with empty cells displayed next to the timer indicates a battery fault. 

●     When the battery is low:

o     You may have animproperly charged battery. If so, re-charge the battery.

o     You may have a loose connection between the pump and battery. If the pump stops when the battery is moved, remove the battery by unscrewing the two screws on the bottom of the pump. Depress the two détentes on the side of the battery and remove the battery. Reattach the battery and tighten the screws on the bottom again, then turn the pump on.

On the Gilair pump, if the battery is insufficiently charged, simply recharge the battery. 


If the pump still will not start, please contact SGS Galson Laboratories at 1-888-432-5227 or Chatlive online with a client service representative.  You can save yourself time and money by knowing these quick fixes, so keep this blog on hand and look for the instructions that come with the pump. And please let us know if you have questions or are experiencing other issues when using SGS Galson pumps.  We’re always available to help with a 24/7 on call service representative – at (315) 569-9027.

No Madness to Our Methods

From the founding of Galson Laboratories to joining SGS, we’ve worked hard at anticipating the needs of our clients. Positioning the right experts in place to meet your needs, while striving for innovation and simplicity has been a cornerstone of our culture. We do this is by adding methods for compounds that are of interest and importance to you. Most recently we added two new methods to our interactive Sampling and Analysis Guide(SAG):

·         Methyl Benzoate on 2um GFF by HPLC in-house method LC-SOP-61

·         Azodicarbonamide on 2um GFF by HPLC  in-house LC-SOP-60

We’ll continue to identify methods that will make your job easier and the workplace safer. Meanwhile, if you are faced with a difficult or non-routine compound to monitor, reach out to us. We can help! Now that we are SGS Galson Laboratories, we are part of an expanded global network, where it’s possible a method for your specific compound already exists; and if not, we will use our resources to identify the best solution for you.

It’s not madness to think we can find that missing method for you. Just ask.

New LOQ's in updated Sampling + Analysis Guide

The online Sampling + Analysis Guidehas been recently updated to reflect some changes in Quantitation Limits (LOQs) related to a few gravimetric analyses and we’ve added a new gravimetric analysis.

Lowered LOQs:

–        Asphalt fume (benzene soluble fraction) by method NIOSH 5042changed from 0.10 mg to 0.050 mg.

–        Cotton dust by method NIOSH 0500using Accu-Cap PVC PW changed from 0.25 mg to 0.10 mg.  

The new addition to the Sampling + Analysis Guide is:

–       Inhalable asphalt fume (benzene soluble fraction) by gravimetric analysis method NIOSH 5042collected with 25PTFE 2.0 PW IOM sampler.

At SGS Galson Laboratories, we are consistently seeking the highest quality data for our clients, and this means understanding the latest methods for sensitivity, accuracy and repeatability. It also means keeping our clients informed. Please contact us with any questions. You can use our IH Live Chat, now available on tablets and mobile phones. We look forward to hearing from you.
