What the CPSC Data Shows
Drain Cleaners (CPSC product code 929, in the Home Workshop Tools & Equipment category) generate an estimated 2,002 emergency-room visits every year in the United States, adding up to roughly 40,048 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 38/100 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 2008 (3,055 estimated ER visits) and the quietest 2005 (1,364 estimated visits).
The single most common ER diagnosis for drain cleaners is poisoning to the all parts body, accounting for approximately 15,544 visits across the 20-year NEISS window, followed by burn, chemical to the eyeball (4,260 cases). The 45-54 age group absorbs the largest share of injuries, about 7,598 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 10.2% of ER visits involving this product end in hospital admission or transfer.
Beyond the hospital-sampled NEISS projections, this page also aggregates 20 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how drain cleaners 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.

Consumer Incident Reports
Reports filed by consumers on SaferProducts.gov.
I suffered chemical burns to the face lips and eyes. The powder had an explosive reaction to the boiling water in the pipe and lacked and warnings or cautions. In addition when searching online onfound alternative directions not calling for the use of boiling water.
The consumer stated that the drain cleaner he was using has an insecure packaging. The consumer was hold the 64 oz. container trying to open it when the plastic film surrounding the top allowed the bottle to slip out of his grasp. The bottle fell vertically to the floor about 3 feet below breaking, resulting in the drain cleaner to spill on to the consumer's legs and feet. The consumer suffered some burns and injuries. The consumer cannot fathom as to why the plastic bottle was not more durable to sustain that fall without breaking. The consumer called the company in March 7, 2011. The consumer was asked for an account of what happened. The consumer went to the doctor that he had first degree burns on his lower legs and feet with second degree on both of his calves. The consumer went to his physician and dressed his legs in medical gauze and left the same day. The consumer went to [redacted]. There was no follow up treatment. The consumer called the firm within the week (date unknown). The consumer mentioned the visit and the firm asked him to send the bottle of the product. The consumer sent the bottle in to the firm in May 2011 at his own expense. The consumer called back the firm a week or two later (date unknown). The firm concluded that their product was just fine and there was no issue. The consumer has yet to call the firm. The product has not caused damage to his house. The product did destroy his shorts and footwear. The Consumer Added: I purchased a bottle of Rooto Corp drain cleaner, named "Professional Drain Opener", from Ace Hardware in Piedmont, CA on Feb 28, 2011. On March 6th, as I have done dozens of times, I was holding the bottle of drain cleaner, which has a plastic outer covering (picture attached), and opening the plastic packaging at the same time. I put a hole in the top of the outer plastic packaging to pull the bottle of drain cleaner out. When I put a hole in the outer plastic packaging the bottle of drain cleaner leaned on th
Unused and never opened bottle of Pro-Strength Liquid Plumr Urgent Clear leaked out of the red cap, solution has run down the back of the bottle and left damage on the shelf floor. The bottle was leaning back in in an under-counter cabinet. The back of the cap is covered with crust, one side of the back label has disappeared. The UPC code is illegible because of the damage on the bottle. I called the recall number for Liquid Plumr and was told that this lot was not part of the current recall. The only visible numbers on the back are: JS15313 and DH-2 22:44.
The consumer received the 2lbs. container of drain cleaner (sodium hydroxide) in a cardboard box. This cleaner is sold in the form of flakes and some of them leaked from the container and damaged the packaging. The packaging got wet somewhere in transport and the consumer noted that water can cause the contents to activate and heat up during the process. This also causes the drain cleaner to combustible. The product was delivered to a work location and fortunately, no one was injured. NOTE: The product was not sealed in child-resistant packaging, and there were no warning labels on the packaging. The consumer believes that JB Tools got hold of a bulk quantity of this product and did not include warning labels when the product was shipped. Therefore, other people who purchase this product could be exposed to a similar risk. (09/30/2024): This complaint concerns my order of a 2 lb size of Thrift Drift Drain Cleaner on Amazon, which was however shipped to me directly from JB Tools. Upon recieving and opening the package, I realized, to my alarm, that the cleaning agent - sodium hydroxide (aka lye, caustic soda), a powerful and extremely toxic, fume-producing substance whose dormant form here is small flakes that get activated by hot water- was only loosely packaged inside a cardboard box. The sodium hydroxide flakes in this package somehow had become exposed to moisture and had started to combust inside the package. Not only that, they were spilling out into the cardboard box, potentially to be touched by and unsuspecting customer, in this case me. They got on my hands but fortunately I was not injured. But such injury could easily happen to other future unsuspecting customers. Finally, there was no warning label on the package, as there is on the 1lb bottle. This is in violation of OSHA regulations. After I conveyed all of this information to the JB Tools customer service representative on August 10, I heard nothing from them beyond a minimal and
After sitting unopened on my garage shelf for three months, this bottle self-imploded. I came home to find the bottle completely mis-shaped, having sucked itself inward, and the contents had spewed out all around where the bottle was sitting.
I bought Nice! drain cleaner from Walgreens and I dropped my shopping bag on a table when I came home and went to the bathroom. While in the bathroom, I heard a leaking sound. I ran out to discover the "child-proof cap" had come off when I dropped the bag and it had leaked everywhere. I immediately opened my windows and proceeded to clean the spill with a baking soda solution and then an ammonia solution. I still came into contact with the corrosive liquid at times which caused me to have to flush my skin with large amounts of cold water and then wash my hands thoroughly. My concern is that a child-proof cap should not be able to come off the way it did, from such a normal activity as dropping a shopping bag on a table. It could happen to anyone and while I have no children or pets, this product presents a real danger to anyone who does. All I suffered was property damage and bouts of lightheadedness easily fixed by breathing closer to a window. What others could suffer is unnecessary harm to children and pets. Upon going to the store to buy ammonia, I discovered that the ammonia I had purchased had a pressure or tamper-proof seal that could have prevented a spill like this. It is my belief that Walgreens should have to package corrosive liquids more securely, whether that means improving on their lid design or adding a seal to the bottle. Either way, the Poison Prevention Packaging Act should address this problem. Thank you for your time and I hope Walgreens Co. is held to full account.
Just after purchasing Liquid Plumr, I placed the Liquid Plumr bottle on the front passenger seat. After making several other stops, I noticed the damage to the passenger seat. The product had leaked out and there is a six inch long, one inch wide hole along the stitching in the seat. I got a pair of work gloves and threw the container in the garbage so no one would touch the leaking container.
Last night I suffered second degree burns on my chest when Comstar Pure Lye Bead Size Drain Opener ejected from my kitchen drain while I was using the product as a drain cleaner. I suffered these injuries despite reading and following the use instructions before using the product to clean my drain. After pouring hot water into the drain, I, after about a minute, poured one cup of the product into the drain. Lye almost immediately ejected from the drain, hitting my chest. I immediately jumped into the shower to rinse myself off, but I still suffered second degree burns.
