What the CPSC Data Shows
School Laboratory Chemicals (CPSC product code 982, in the Home Workshop Tools & Equipment category) generate an estimated 364 emergency-room visits every year in the United States, adding up to roughly 7,284 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 30/100 for this category (low risk), combining raw injury volume, demographic reach, severity of outcome, and multi-year trend. The five-year trajectory shows that injury counts are roughly flat over the last five years, with the busiest year on record being 2024 (666 estimated ER visits) and the quietest 2013 (122 estimated visits).
The single most common ER diagnosis for school laboratory chemicals is poisoning to the all parts body, accounting for approximately 2,360 visits across the 20-year NEISS window, followed by derma/conjunct to the eyeball (818 cases). The 15-24 age group absorbs the largest share of injuries, about 4,962 cases over the NEISS window, and females appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 3.8% of ER visits involving this product end in hospital admission or transfer.
Beyond the hospital-sampled NEISS projections, this page also aggregates 2 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how school laboratory chemicals fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

Hello, my name is [REDACTED]. Mother of a [REDACTED]. She attends [REDACTED] Elementary, at [REDACTED], MI. My daughter and half her class had a severe chemical reaction to your product. It was used by Ferris State Univeristy in Michigan to teach the kids about hand-washing . It occurred on . 11-10-17. The teachers called us parents inside for a special meeting. Half the class had ice bags on I their bright red, itching faces, necks and hands. The school said it may have been contact dermatitis and ---to-ke p-an -eye-Gn-th&--kids They-saiEl-te-see-a-ElGGter--if/when-needed.,- I--teelr[REDACTED]-te-the-ER-that-day. - The ER doctor said it looked like a chemical burn and it was not a contagious illness. They prescribed medication. My daughter's face hurt to even touch it for 5 days. It itched severely, even after the redness left it (after meds were given) . [REDACTED] has a scar from the burn :m her face, now. It slowly healed. [REDACTED] told me that other kids told her, that it burned their hands when they touched the glow-in-the dark lotion. [REDACTED] said that wherever they touched their hands, it burned and itched severely. I saw half her class with ice bags on their faces. They all had a severe reaction. It occurred at the same time, after they used the lotion. I found out that that batch was used at [REDACTED]. The school nurse ([REDACTED]) said that they disposed of that batch and that batch wont be used again. The principal called me last week and told me: the school wont use that lotion again and not on my daughter. I am still very concerned, that it may not have been just that batch. It may have been the product in general. It affected half the children in her class and my daughter, severely. My daughter and others sought medical care. I am concerned about anyone using this product, esp those with chemical allergies (like my daughter and -her class). I pray that this email gets noticed . I don 't see the school calling the
I experienced long-term chemical exposure from an unused chemistry lab kit made by Science Interactive. It was stored in its original box in a shared bedroom up on a shelf in the closet. Without my knowledge, the liquid chemicals were evaporating and forming gases, causing me respiratory issues for months starting around February 2023. I had it for a year and a half when the respiratory issues started because of the kit. I experienced coughing if I had been near where the kit was stored, such as sitting at my desk, and I would also get a burning sensation in my lungs. During these months the burning feeling would last around half an hour after leaving the area and would become a lighter irritation after more time passed. I noticed that the symptoms would only start when I was in my room around that area. Not knowing the cause, I got an air purifier for the desk, which didn't help. I also searched for mold, and I contacted a testing company. I suspected a chemical was causing the symptoms, but I didn't suspect the kit at that point because nothing inside had been opened. I was concerned and tried to avoid the area while also trying to figure out the cause. I then started to clean out the room. In May I emailed Science Interactive asking how to dispose of the unused lab kit. On May 31st I opened the box and saw that the chemicals had been evaporating because there was little liquid in the bottles. I was scared but quickly took a few pictures to show a professor and then closed the box. Minutes later I started coughing and experiencing the familiar burning sensation, so I then knew this was what had been causing my respiratory issues. I messaged a professor and brought the kit to campus with the help of her instructions. Even after removing it, I continued to experience the burning sensation for many days. I emailed Science Interactive explaining the situation and asked to speak with someone about their product's safety or a chemistry expert. There were so many liqu
