You can get taken to the cleaners in civil court if you deny workers comp or disability to someone with a dumb workstation configuration. In that way, its actually more effective than OSHA fines which can't even keep furniture companies from feeding carpenters to sofas.

I love how the dude says "and I know the safety guys are already jumping out of their seats" while waving the pipette he just used to transfer HF around, wearing the wrong gloves, still having exposed skin and not working under a fume hood.
Seriously: HF hates you and wants to eat your bones. It's not something you want to screw around with like this guy appeared to do.

A fatal accident occurred in a palynological laboratory in Australia, resulting in the death of a technician. This article looks at the factors that may have contributed to its occurrence.

A standard geology technique, which involved the dissolving of sedimentary rock with mineral acids (hydrochloric and hydrofluoric acid), was being undertaken in a fume cupboard. The technician involved was believed to be seated when he knocked over a small quantity (between 100 - 230ml) of hydrofluoric acid (HF) onto his lap, splashing both thighs. The only personal protective equipment worn was two pairs of wrist length rubber gloves and a pair of polyvinyl chloride sleeve protectors. As a result of the fact that the technician was working alone, it is unclear whether the spill was from the digestion cup or the 2-1 bulk acid container. The technician sustained burns to 9% of his body surface area, despite washing his legs with water from a makeshift plumbing arrangement that supplied water at 6 litres/min. No calcium gluconate gel was applied to the affected area and contaminated clothing was not removed during the flushing with water. Following flushing, the technician, who appeared to be in severe pain and shock, immersed himself in a chlorinated swimming pool at the rear of the workplace, where he remained for approximately 35-40 minutes before ambulance help arrived.

The injured man was hypothermic and hypocalcaemic on admission to an intensive care unit at a nearby hospital, and soon became unconscious. His condition continued to deteriorate despite, subcutaneous injections of calcium gluconate and administration of intravenous calcium and magnesium. His right leg was amputated 7 days after the incident.

He subsequently died from multi-organ failure 15 days after the hydrofluoric acid spill.

Points from accident investigation

Investigation showed that this death could have been prevented if adequate personal protective equipment had been worn during the handling of concentrated hydrofluoric acid.

Full length PVC coveralls with sleeves to the wrist or a full-length PVC apron with sleeve protectors, a face shield, rubber boots, safety goggles and mid-arm length PVC gloves should have been worn by the deceased when HF was being used in the fume cupboard.

The deceased did not have access to an emergency shower to remove the HF, instead the skin was washed from a hose that provided water at a very low flow rate. Because of the low flow rate, the volume of water may have spread the HF onto other parts of the skin.

No calcium gluconate gel was applied following dermal exposure. Inhalation may also have been another route of exposure due to the relatively high vapour pressure of HF acid.

Ergonomics

An ergonomic assessment of the work station indicated the following: (i) The working height of the fume cupboard was too low (by between II 0 and 160mm) for the technician to work comfortably in a standing position. Sitting increased the body surface area. (ii) Instability of the digestion cups due to lightweight construction (height 75mm, diameter of base 59mm, diameter at top 78mm), made of 2mm polyethylene. (iii) Lack of available space in the fume cupboard, entrance of the fume cupboard was 470mm wide and 410 mm high. (iv) As a result of the design of the container, decanting from the 2-1 hydrofluoric acid container was awkward, involving the pronation of the forearm.

The laboratory personnel could have minimised the likelihood of a spill through the introduction of cup supports for the digestion cups. Other ergonomic factors which may have reduced the likelihood of a spill include:

1. Provision of a fume cupboard that had more working space;

2. Use of smaller sized bottles or better designed 2-1 70%w/w hydrofluoric acid containers (to minimize awkward pouring postures) or introduction of a graduated dispensing unit to negate pouring the acid;

3.Provision of an appropriate bench height for the operator.

Overall, it was noted that the laboratory did not comply with requirements of national standards in the areas of emergency procedures, safe handling and disposal of the chemical and laboratory design.

ACUTE: Skin, eyes, respiratory system.
CHRONIC: Skin, respiratory system, bones.
EYE CONTACT: may cause severe irritation with possible corneal burns.
SKIN CONTACT: causes severe burns and fluoride-like burns which may not be immediately evident. Skin contact may cause hypocalcemia by skin absorption. The fluoride components of this product can penetrate the skin and destroy the deep tissue layers, including bone tissue. This damage to the body's tissues may continue for days, as the fluoride ion reacts with the calcium in the skin and bone. Severe skin-contact exposures (especially when the skin contamination exceeds 160 cm2) can cause hypocalcemia, a life-threatening lowering of serum calcium in the body.
INHALATION: may cause irritation to the respiratory tract and lung damage if exposure is excessive.
Inhalation may lead to hypercalcemia, due to absorption of the fluoride components. Chronic, low-level inhalation exposure may cause bronchitis, dental erosion and perforation of the nasal septum. Chronic, lowlevel inhalation may also cause baritosis, which is benign form of pneumoconiosis, due to the Barium Sulfate component. There are several reports of death due to acute hypersensitivity reaction and acute inflammation of the bronchi and peripheral airways after accidental inhalation of barium sulfate.
INGESTION: can cause very serious damage to the mouth, esophagus, stomach, and other tissues with which contact is made. Reported symptoms of ingestion of fluoride salts, such as in this product include salivation, nausea. Repeated small doses may produce no other symptoms, but polyuria and polydipsia have also been reported. Large doses lead promptly to burning or crampy abdominal pain, intense vomiting and diarrhea, often with hematemesis and melena, dehydration and thirst, muscle weakness, tremors, and rarely transient epileptiform convulsions, preceded or followed by progressive central nervous depression (lethargy, coma and respiratory arrest, even in the absence of circulatory failure), shock characterized by pallor, weak and thready pulse (sometimes irregular), shallow unlabored respiration, weak heart sounds, wet cold skin, cyanosis, anuria, dilated pupils, followed almost invariably by death in 2 to 4 hours. Even in the absence of shock, arrhythmias may occur, especially multiple episodes of ventricular fibrillation leading eventually to cardiac arrest. If the victim survives a few hours, paralysis of the muscles of deglutition, carpopedal spasm, and painful spasms of the extremities, occasionally localized or generalized urticaria. The above signs and symptoms are related to a variety of metabolic disorders that may occur in acute fluoride poisoning, including hypocalcemia, hypomagnesaemia, metabolic and/or respiratory acidosis and sometimes hyperkalemia. Ingestion may be fatal.

wikipedia posted:

Polymer fume fever or fluoropolymer fever, also informally called Teflon flu, is an inhalation fever caused by the fumes released when polytetrafluoroethylene (PTFE, known under the trade name Teflon) is heated to between 300 °F (149 °C) and 450 °F (232 °C). When PTFE is heated above 450 °F (232 °C) the pyrolysis products are different and inhalation may cause acute lung injury. Symptoms are flu-like (chills, headaches and fevers) with chest tightness and mild cough. Onset occurs about 4 to 8 hours after exposure to the pyrolysis products of PTFE. A high white blood cell count may be seen and chest x-ray findings are usually minimal.

The polymer fumes are especially harmful to certain birds whose breathing, optimized for rapidity, allows toxins which are excluded by human lungs. Fumes from Teflon in very high heat are fatal to parrots,[1] as well as some other birds (PTFE Toxicosis).[2]

It is, of course, extremely toxic, but that's the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.
