This story may be longer than necessary, but the incident happened 70 years ago, so I felt I needed to explain some things first. The mid-to-late 1950s was a completely different world when it comes to personal safety. It was a lot like the Wild West as nobody wore seatbelts in cars and kids never wore helmets. Parents in the mid-to-late 1950s were deeply concerned with child safety, but their anxieties focused on different threats than those that worry parents today. Children enjoyed greater freedom to roam outside unsupervised, while parents faced massive, uncontrollable public health crises and emerging social anxieties. The greatest terror for mid-century parents was the poliovirus. Every summer, rising temperatures brought panic, leading parents to keep children away from public swimming pools, movie theaters, and neighborhood crowds out of fear of paralysis or death. This widespread fear largely subsided only after Jonas Salk’s vaccine became widely available in 1955. At this time, society was deeply worried about the moral safety and behavior of youth. Most parents were not worried about their children being safe when they were playing in the neighborhood and many families didn’t lock their doors. The mid-1950s saw congressional hearings investigating comic books and television as corrupting influences that supposedly incited violence and juvenile delinquency.
Products started featuring safety caps in 1967 following the invention of the first child-resistant closure, with widespread mandatory use beginning after the passage of the Poison Prevention Packaging Act in 1970. Canadian pediatrician Dr. Henri Breault invented the “Palm ‘n Turn” cap, which was the first modern push-and-turn child-resistant closure, after he saw high rates of accidental child poisonings from medications. The United States Congress passed the Poison Prevention Packaging Act (PPPA), signed by President Richard Nixon in 1970, requiring special child-safe packaging for prescription drugs, over-the-counter medications, and hazardous household chemicals. The newly formed Consumer Product Safety Commission (CPSC) took over enforcing these rules, making safety caps standard and dropping child poisoning rates dramatically. Child safety locks for cabinets were invented and patented as early as the late 1950s (such as a 1959 patent filing), but they did not become widely used or mass-marketed until the broader child safety movement took off in the 1970s and 1980s.
Household ammonia was extremely common in mid-to-late 1950s homes, serving as one of the primary go-to options for heavy-duty household cleaning. During this post-World War II era, the cleaning landscape was shifting toward commercialized, chemically formulated products. In the 1950s households utilized ammonia as a glass cleaner, because it evaporates incredibly fast without leaving streaks behind, it was the absolute standard for washing windows, mirrors, and glass surfaces. It was also used on linoleum floors, vinyl tiles, and Formica countertops, as a grease cleaner. Housekeepers regularly relied on diluted jugs of pure household ammonia to strip old floor wax and cut through stubborn kitchen grease.
When my younger brother was an infant, he was crying on the kitchen floor next to a spilt bottle of ammonia after he got into the cabinet where my mom stored her cleaning supplies. You can’t ask an infant what happened, so you need to assume the worst. He was laying on the floor crying and my parents took him to the emergency room where his stomach was pumped out in case he swallowed any of it and his eyes were also washed out. Ammonia reacts with moisture in the eye to form ammonium hydroxide. This chemical destroys cell membranes quickly through a process called liquefactive necrosis. Alkali chemicals penetrate eye tissues in seconds. The limbus holds the stem cells that repair the surface of the eye, his cornea. The limbus is the border area where the cornea (the clear front window of the eye) meets the white sclera (the outer wall of the eye). He did heal completely because he got immediate treatment and proper medical care that included antibiotic drops, and lubricants and if he did have a chemical burn on his eyes, it was moderate not severe. He was lucky that his limbus contained vital stem cells that repaired the surface of.
My brother developed a deep, lasting fear of going anywhere near ammonia as an adult, due to his distressing childhood injury. Ammonia has become an everyday annoyance and a persistent problem that ruins my brother’s peace of mind and frustrates him on a regular basis. The brain is highly efficient at linking intense physical pain or panic with the specific environmental triggers present at the time. When a child experiences an ammonia spill like my brother did, their brain registers the distinctive, sharp scent and sight of the chemical bottle as an immediate threat to survival. As an adult, encountering that same smell can instantly trigger an automatic, involuntary “fight-or-flight” survival response.
