Human hair and matches: The sulfur content in human hair is responsible for its characteristic smell when burned, which can mask unpleasant odors. The burning of a match is the primary factor in masking odors, not the match itself.
The characteristic smell of burning hair is due to its sulfur content, which is similar to the smell produced when lighting a match. This sulfur content can overpower other unpleasant smells in our olfactory recognition. The connection between matches and masking unpleasant smells, such as feces, was discussed, and it was clarified that the lighting of the match is the primary factor in masking the smell, not the burning of the match itself. Interestingly, some research on the flammability of human hair has been conducted in the context of space exploration, highlighting the importance of understanding the properties of human hair in various environments.
Spacecraft fires in oxygen-rich environments: Human skin and hair can ignite more easily in oxygen-enriched atmospheres, increasing the risk of fires in spacecraft or space exploration environments. Precautions like using inert gases or protective measures are necessary.
Elevated oxygen levels can significantly increase the risk of fires in spacecraft or space exploration environments. This was highlighted in a 1968 study that investigated the flammability of human skin and hair in oxygen-enriched atmospheres, likely referencing the Apollo 1 fire tragedy. The study found that while human skin and hair are not easily flammable due to their high water content, the outer layers can ignite more easily in such environments. The researchers suggested using inert gases like helium or protective measures like lotions and flame-resistant materials to mitigate this risk. More recently, a 2009 paper reiterated this concern, emphasizing that supplemental oxygen provided through masks can create localized environments with even higher oxygen concentrations, increasing the risk of fires. As space exploration continues to evolve, it's crucial to be aware of this risk and take appropriate precautions.
Spacecraft fires risk: To limit the risk of fire in spacecraft, control access of ignition sources to fuel by removing combustible materials or making them less combustible, such as keeping oxygen sources away from patients during defibrillation and trimming astronauts' hair using vacuum hoses.
The use of medical equipment and procedures, such as defibrillation and cauterization, in an oxygen-rich environment, like those found in spacecraft, can pose a risk of fire due to the presence of fuel in the form of potentially flammable clothing and hair. This risk is compounded by the fact that it's impossible to eliminate all ignition sources in a spacecraft environment. Therefore, the best way to limit the risk of fire is to control access of those ignition sources to fuel by removing combustible materials or making them less combustible. For example, during defibrillation, oxygen sources should be kept away from the patient's chest, and chest hair should be trimmed. In addition, astronauts may need to undergo space haircuts using vacuum hoses to contain the clippings in microgravity. It's important to consider these factors when planning future space missions, especially those involving the need for supplemental oxygen.
Human hair flammability in space: Increased oxygen concentrations lead to faster flame spread rates for human hair, increasing the risk of injuries for astronauts. Strategies like hair coverings, shaving, or using flame-resistant materials can help mitigate this risk.
Human hair becomes significantly more flammable in high oxygen environments, which is a potential safety concern for astronauts in future space exploration missions. The authors of a recent study found that increasing oxygen concentrations led to faster flame spread rates for human hair, with longer hair exhibiting continued bulk burning. This could result in serious injuries if an astronaut's head were engulfed in flames before they could be extinguished. To mitigate this risk, acceptable strategies such as hair coverings, shaving, or using flame-resistant materials have been suggested. The study's findings also sparked some creative thoughts about potential sci-fi ramifications, such as astronauts adopting special hair styles or using flame-retardant jellies. Overall, this research underscores the importance of considering various safety factors, even the seemingly mundane ones like human hair, in the planning and execution of space exploration missions.
Blackbeard's slow matches: The myth of Blackbeard using slow matches in his beard during boarding actions may not be true, as it's unlikely pirates would risk fire and smoke with matches burning in their beards.
The myth of Blackbeard the Pirate using slow matches in his beard during boarding actions may not be entirely true. While it's possible that pirates carried slow matches in their hats or near their grenades, the idea of having them burning in close proximity to a wild beard seems unlikely due to the risk of fire and smoke. Historians believe that the myth may have originated from fictional accounts, such as Captain Charles Johnson's "A General History of the Robberies and Murders of the Most Notorious Pirates," which may have mixed fact and fiction. Instead, pirates more commonly carried slow matches tied to their clothing or hat with a match case.
Pirate flares: Pirates may have used flame-resistant gels or jellies instead of lighting fuses in their beards during boarding actions due to the impracticality of carrying and keeping a long match in place
Pirates, such as Blackbeard, were known for their dramatic flair, including lighting fuses in their beards during boarding actions. However, the plausibility of this is questionable due to the potential weight and difficulty of keeping a long match in place in a beard. Alternatively, flame-resistant gels or jellies could have been a possibility in the 17th and 18th centuries. Pirates were resourceful individuals, and some may have had access to such information or figured out solutions themselves. Yet, the risks involved in such actions suggest that pirates were making questionable life choices. The idea of flaming hair and beards in mythology and folklore will be explored further in the next episode. Stuff to Blow Your Mind is a science and culture podcast with core episodes on Tuesdays and Thursdays, short-form episodes on Wednesdays, and a "Weird House Cinema" rerun on Fridays. Listeners are encouraged to share their thoughts on the experiment with the Monday listener mail episodes and other topics, including pirate lore and the use of flamethrowers in science fiction.
