[whats-in-a-sentence]

As shown in figure 13.58, this is an enormous chemical reactor in which heating, reduction and purification occur together.

i have once more Read a Book !

the book was jim morris' cancer factory: industrial chemicals, corporate deception, & the hidden deaths of american workers. this book! is very good! it is primarily about the bladder cancer outbreak associated with the goodyear plant in niagara falls, new york, & which was caused by a chemical called orthotoluedine. goodyear itself is shielded by new york's workers' comp law from any real liability for these exposures & occupational illnesses; instead, a lot of the information that morris relies on comes from suits against dupont, which manufactured the orthotoluedine that goodyear used, & despite clear internal awareness of its carcinogenicity, did not inform its clients, who then failed to protect their workers. fuck dupont! morris also points out that goodyear manufactured polyvinyl chloride (PVC) at that plant, and, along with other PVC manufacturers, colluded to hide the cancer-causing effects of vinyl chloride, a primary ingredient in PVC & the chemical spilled in east palestine, ohio in 2023. the book also discusses other chemical threats to american workers, including, and this was exciting for me personally, silica; it mentions the hawks nest tunnel disaster (widely forgotten now despite being influential in the 30s, and, by some measures, the deadliest industrial disaster in US history) & spends some time on the outbreak of severe silicosis among southern california countertop fabricators, associated with high-silica 'engineered stone' or 'quartz' countertops. i shrieked about that, the coverage is really good although the treatment of hawks nest was very brief & neglected the racial dynamic at play (the workers exposed to silica at hawks nest were primarily migrant black workers from the deep south).

cancer factory spends a lot of time on the regulatory apparatus in place to respond to chemical threats in the workplace, & thoroughly lays out how inadequate they are. OSHA is responsible for setting exposure standards for workplace chemicals, but they have standards for only a tiny fraction—less than one percent!—of chemicals used in american industry, and issue standards extremely slowly. the two major issues it faces, outside of its pathetically tiny budget, are 1) the standard for demonstrating harm for workers is higher than it is for the general public, a problem substantially worsened during the reagan administration but not created by it, and 2) OSHA is obliged to regulate each individual chemical separately, rather than by functional groups, which, if you know anything at all about organic chemistry, is nonsensical on its face. morris spends a good amount of time on the tenure of eula bingham as the head of OSHA during the carter administration; she was the first woman to head the organization & made a lot of reasonable reforms (a cotton dust standard for textile workers!), but could not get a general chemical standard, allowing OSHA to regulate chemicals in blocks instead of individually, through, & then of course much of her good work was undone by reagan appointees.

the part of the book that made me most uncomfortable was morris' attempt to include birth defects in his analysis. i don't especially love the term 'birth defect'—it feels cruel & seems to me to openly devalue disabled people's lives, no?—but i did appreciate attention to women's experiences in the workplace, and i think workplace chemical exposure is an underdiscussed part of reproductive justice. cancer factory mentions women lead workers who were forced to undergo tubal ligations to retain their employment, supposedly because lead is a teratogen. morris points at workers in silicon valley's electronics industry; workers, most of them women, who made those early transistors were exposed to horrifying amounts of lead, benzene, and dangerous solvents, often with disabling effects for their children.

morris points out again & again that we only know that there was an outbreak of bladder cancer & that it should be associated with o-toluedine because the goodyear plant workers were organized with the oil, chemical, & atomic workers (OCAW; now part of united steelworkers), and the union pursued NIOSH investigation and advocated for improved safety and monitoring for employees, present & former. even so, 78 workers got bladder cancer, 3 died of angiosarcoma, and goodyear workers' families experienced bladder cancer and miscarriage as a result of secondary exposure. i kept thinking about unorganized workers in the deep south, cancer alley in louisiana, miners & refinery workers; we don't have meaningful safety enforcement or monitoring for many of these workers. we simply do not know how many of them have been sickened & killed by their employers. there is no political will among people with power to count & prevent these deaths. labor protections for workers are better under the biden administration than the trump administration, but biden's last proposed budget leaves OSHA with a functional budget cut after inflation, and there is no federal heat safety standard for indoor workers. the best we get is marginal improvement, & workers die. i know you know! but it's too big to hold all the same.

anyway it's a good book, it's wide-ranging & interested in a lot of experiences of work in america, & morris presents an intimate (sometimes painfully so!) portrait of workers who were harmed by goodyear & dupont. would recommend

#if anyone knows about scholarship that addresses workplace chemical exposure #& children born with disabilities through a disability justice lens please recommend it to me! #booksbooksbooks #have reached the point in my Being Weird About Occupational Safety era where i cheered when familiar names came up #yay irving j. selikoff champion of workers exposed to asbestos! yay labor historians alan derickson & gerald markowitz! #morris points out the tension between workers - who want engineering controls of hazards (eg enclosed reactors) #& employers who want workers to wear cumbersome PPE #the PPE approach is cheaper & makes it even easier to lean on the old 'the worker was careless' canard when occupational disease occurs #i just cannot stop thinking about it in relation to covid. my florida library system declined to enforce masks for political reasons #& reassured us that PPE is much less important than safety improvements at the operational & engineering level #but they didn't do those things either! we opened no windows; upgraded no HVACs; we put plexi on the service desks & stickers on the floors #& just as we have seen covid dangers downplayed or misrepresented workers still do not receive useful information about chemical hazard #a bunch of those MSDS handouts leave out carcinogen status & workers had to fight like hell to even be told what they're handling #a bunch of them still do not know—consider agricultural workers & pesticide exposures. to choose an obvious & egregious example.

Shit like that thing I just reblogged literally terrifies me so much I'm shaking and tearing up rn. I'm weirdly drawn to art about it though like I hope that if I can expose myself to people who describe the beauty in it like that post maybe I'll get like, desensitized but instead I just end up making myself really upset

#it's not just molten metal it's also mines and chemicals and big mechanical machines and elevators and nuclear reactors #and basically any kind of heavy industry #it's like legitimately a phobia but I can't find a name for it or other people who have it

i understand its very very important but how they capitalize here reminds me of when im being goofy and over the top enthusiastic about stuff

edit: gathering the screenshots of me for these examples started a thing where me and sluggo (Laplace’s Angel) here read out the cesium excerpt. both of our attempts were pinned bc they were hilarious XD

these are examples of me being silly after getting out of a shower, spending a few extra mins to reply to smthn before i leave, sobbing over side profiles and old attempts at such, and a reply to a perch perkins + squillium fanart that was pinned earlier in the 🌀hyperfix-hyperfix channel. good times :3.

profile picture is a silly frame from @neon-catarina ‘s Chonny’s Inferno anination thing!! sorry for the ping 👀💧 this def doesnt relate to cj in any way lmao. my username is a playon-words of ‘chonny doll’ but idk why theres and extra L like its ‘lol.’ originally was ‘clog’ but that was odd. the chonny toothpick puppet doll thing in that animation was my favorite,,
