NASA's Hazardous Material Summary Tables: A Crucial Tool for Safe Space Travel
To ensure the safety of astronauts on space missions, NASA has developed a crucial tool called Hazardous Materials Summary Tables (HMSTs). These tables compile information on the chemical, biological, and flammability hazards associated with materials used on specific flights or missions.
The Johnson Space Center (JSC) plays a pivotal role in evaluating the toxic hazard level of liquids, gases, particles, or gels that will be flown on or to any manned U.S. spacecraft. JSC's toxicologists assess this hazard and assign a BioSafety Level (BSL), which indicates the potential biological risks associated with a material. Additionally, materials experts evaluate flammability levels, assigning a Flammability Hazard Level (FHL) that determines the risk of fire.
The HMSTs are an essential component of NASA's Safety for all Programs, including the International Space Station (ISS), Commercial Crew Program, Multi Purpose Crew Vehicle (MPCV), and Gateway missions. These tables are used in conjunction with a computerized database called HazMat to document hazardous materials flown on or to spacecraft.
To ensure accurate data submission, NASA has established specific requirements, outlined in JSC 27472. This document defines the terms "chemicals" and "biological materials" and specifies who must provide information to JSC toxicologists about the materials to be flown on U.S. spacecraft.
For all ISS flights and Artemis missions (Orion, Gateway, and Human Lander System), NASA recommends using the electronic hazardous materials summary table (eHMST) tool for data submission. However, if you don't have access to this tool, you can submit a request for access through the NAMS system.
Additionally, NASA encourages payload providers to submit biological and chemical data to the Russian Institute for Biomedical Problems for experimental payloads planned for launch on Russian vehicles or operated in the Russian Segment of ISS.
Toxicological hazard assessments are conducted according to JSC 26895 guidelines. The resulting Toxicity Hazard Level (THL) is combined with the BioSafety Level (BSL) and Flammability Hazard Level (FHL) to determine the combined Hazard Response Level (HRL). This HRL serves as a critical factor in labeling and operational response for each flight, following rule B20-16.
In summary, HMSTs are an indispensable tool for ensuring the safety of astronauts on space missions. NASA's stringent requirements and guidelines underscore the importance of accurate data submission to prevent potential hazards associated with hazardous materials flown on or to spacecraft.

THE FACT THAT THEY HAVE THESE HAZARDOUS MATERIALS SUMMARY TABLES AND TOXICOLOGICAL HAZARD ASSESSMENTS IS JUST MIND-BLOWING. IT'S LIKE, WE'RE NOT JUST TALKING ABOUT SPACE TRAVEL, WE'RE TALKING ABOUT PREVENTING ACCIDENTS THAT COULD KILL PEOPLE! 
. I mean, can you even imagine being on a mission without knowing what kind of hazardous materials are in your suit? It's crazy that NASA has developed these tables to help us prepare for those kinds of situations. But at the same time, I'm also thinking about all the astronauts who have been affected by toxic exposure before... it's like, we're making progress but there's still so much work to be done 
. I just hope that one day we can send people on missions without worrying about their safety as much 
! I mean, think about it, astronauts are literally venturing into space and who knows what kinda crazy stuff they're gonna encounter out there? It's gotta be super important to have a plan in place for all the weird chemicals and biological materials they might come across. And from what I'm reading, these tables are like a game-changer for safety. I love that NASA is being so proactive about it too - they've got all these guidelines and requirements in place to make sure people know what's safe and what's not. It's awesome that they're working with the Russian Institute for Biomedical Problems too! Now, I'm no rocket scientist or anything 
but even I can see that this is a big deal. Let's hope it helps keep our astronauts safe on those epic space missions 
. Like, what took us so long?!? We need to make sure our astronauts are safe out there, and if we can't even get this right on our own missions, then we can't trust ourselves to partner with other countries like Russia for certain experiments 
.
. I feel like NASA needs to streamline their process and make it easier for people to access the information they need 
. It seems like a lot of hoops to jump through (literally, who comes up with this stuff? 
.
. It's all about weighing the pros and cons, being thorough, and making sure everyone involved knows what they're getting themselves into. And honestly, I think that's a valuable lesson for us all - we can learn from their attention to detail and commitment to safety 
this is so lit! I'm literally hyped that NASA has created these Hazardous Materials Summary Tables 
. And I love how NASA is being super transparent about who needs to submit data and where, it's all so organized and easy to follow 
. This is literally a dream come true for any space enthusiast like me 
, but I gotta say, I think HMSTs are a total game-changer for space travel safety. Like, can you imagine if there was an accident and nobody knew which materials were toxic or flammable? It's crazy to think about the risks involved. NASA is definitely being super proactive about this stuff. The fact that they have these tables and databases in place to document hazardous materials is just mind-blowing to me. And it makes total sense that they're making it easy for payload providers to submit data to ensure everything is safe. I'm gonna start following NASA's updates on this now, seems like a really important topic
