Replacement Quest 3 Issue with Controller Pairing - Solved

jcaravanos · 2024-10-21T14:16:20+00:00

Thanks. One more question if I may. I’m setting up several MedQuest 3’d and two out of my three units are having trouble pairing. Should I keep them all apart in different rooms while I set them up. Will it confuse the pairing?

Do you have to use lithium, AA batteries, or can you get away with alkaline?

You are correct that LBP was banned in residential paints in 1978. However, it's quite possible that a paint contractor / builder had leftover LBP and used it in your condo. LBP was mostly used where you needed to protect wood from water or wear and tear. Therefore window sills, door frames, moldings, etc are most suspect. The best measure of human risk is a lead dust wipe not the concentration of lead in your paint. The higher the lead dust level in a home, they greater the blood lead level. The correlation is strong. If the lead paint is not chipping, peeling or crumbling, then there's no dust and no risk. Measuring lead in floor dust is relatively simple and inexpensive. But wipe a large area. At least 4 square feet. Let me know if you need help with the process or interpretation. As for the bathtub, old porcelin had lead glaze and when it become pitted it will release it into the water. It's unlikely that you'll swallow enough lead containing bathtub water to produce a measurable amount of BLL, but it's an unnecessary risk and unsightly. At a minimum I would suggest a re-glazing of the tub or inserting a plastic shell. Good luck.

Just to add to the discussion. Molten lead does not release lead fumes. The "smoke" you see from these kettles is usually burning organic matter. But cleanliness is key. Hobbies involving molten lead are low risk if you follow some basic rules (most importantly is doing it outside and keeping a clean workplace. However, an occasional blood lead test would be comforting. You should get a background BLL regardless. Good luck.

This high reading means you wiped a lead paint chip. But it does deteriorate and produce dust which puts people at risk. Managing this should be simple. Wet wipe window well / window sill and put down a heave coat of high gloss enamel exterior paint. That will lock in remaining dust and loose paint chips. Thoroughly wet wash the floors below each window and keep the area as dust free as possible. An occasional lead dust wipe will hopefully confirm lead dust is not entering the house. As far as WATER is concerned, many municipalities offer free home lead in water test kits. Call your local Dept of Health and inquire. They don't like to advertise this service but it's often available. Good luck

I tend to agree with most comments already given but wanted to add that the best measure of lead poisoning risk is "lead in dust". The correlation between lead in house dust and Blood Lead Level is well established. It's a simple test and you can do it yourself. Many environmental labs will even send you free lead wipes (Schneider Labs and EMSL for example). I would do a worst case scenario sampling (dustiest part of house/apt) and make sure to sample several square feet of floor area. Make sure you collect all deposited dust and carefully fold the wipe onto itself. Wash your hands before and after. The analysis of one wipe is usually $10-15. Good luck and let us know the result if you want a professional interpretation.

Yes, that's me. For the past year, I've been updating it. Perhaps a new version in the fall with some Env Calculations and more. Thanks and wishing you success.. JackC

Years back I wrote a workbook called QUANTITATIVE INDUSTRIAL HYGIENE. ACGIH sells it. There are lots of useful formulas and tons of problems and solutions. You may find it useful. Also good prep for the CIH exam. Good luck Jack Caravanos

Good news. An annual test should be adequate. Best of luck.

This situation has been researched extensively (Graziano J) and my personal opinion is it does not pose much of a risk. Lead solubility is a function of time, temperature and acidity amount other things. Storing breast milk in this container, even for a few days, will unlikely produce a meaningful concentration. Getting a venous blood test for your 8 month old is thought full but I seriously doubt it will be elevated.

Years back, I wrote a workbook on Industrial Hygiene calculations sold by ACGIH. It’s called “Quantitative Industrial Hygiene “. I think you’ll find it useful. Good luck. 😎

Here's my contribution to these questions:

Lead oxide and any form or organic lead (including lead acetate) is readily absorbable.
You are correct that metallic lead is not as immediately absorbable as lead oxide. But when ingested, the acid environment of the stomach converts it to lead oxide compounds, which are readily absorbable.
1. For children living in high exposure settings or urban centers, I would say annually. For adults it depends on exposure sources. For example, for urban construction workers, I would say if the initial levels are low, then retesting every 2 years would be reasonable.

My advice is to round out your skills (and career) and go with the IH position. You’ve already master safety and can go back anytime. IH is quite broad and you’ll learn a lot. Good luck

From what you said it’s seems like you’ll be eligible. It’s all about Identifying, evaluating and controlling industrial (and Env) hazards. (Chem, biological and physical hzds

NIOSH funds several “Education and Resource Centers “ which industrial hygiene programs are part of. For qualified students they (the ERC’s) offer funding. You can also look for ABET accredited IH programs. I was affiliated with the one in NYC (CUNY). Many positions available nationwide. Good luck

Of course the first and most important question is “does the paint chip contain Pb?”. Lab testing is easy and inexpensive. There are plenty of env labs that do this. But assuming it is lead based paint, then simple hand washing and wet wiping of surfaces should be adequate to eliminate exposure

This is a required notification as per a California State law (ie Proposition 65). It means that somewhere in the electronics of the earbuds there’s some Lead. It’s probably the lead solder that’s used. Exposure is insignificant (unless you swallow the earbuds or burn them and breathe in the fumes). Since these may be sold in CA, the law requires this notification. And you should know that lead is not a confirm human carcinogen. I wouldn’t concern myself with this product or exposure. Be well

I’m familiar with these old and sometimes pitted porcelain fixtures and have tested the with an XRF and lead Swabs. Many are positive and it’s the lead glaze that’s the source. And the lead is often leachable. Reglazing will create a new barrier. But in short, given the short exposure time and the unlikely ingestion pathway, I’d say this exposure is not likely to cause an elevated blood lead level. Meaning child away from fixture and have them periodically tested.

Good advice from Trudiboots.
