The background to the treaty was the extensive medical problems such as phossy jaw facing workers in match production.

White phosphorus was poisonous to match makers, causing Phossy jaw.

Young girls worked at match factories, where phosphorus fumes would cause many to develop phossy jaw.

Those with phossy jaw would begin suffering painful toothaches and swelling of the gums.

Chronic white phosphorus poisoning leads to necrosis of the jaw called "phossy jaw".

They were also prey to industrial illnesses, like the bone-rotting Phossy jaw, which was caused by the chemicals used in match manufacture.

Breathing in phosphorus in its gaseous form can cause an industrial disease called "phossy jaw", which eats away the jawbone.

Nissen was especially concerned about the danger of contracting phossy jaw, and famously spoke at a public meeting together with Bjørnstjerne Bjørnson.

This is derived from the 19th-century term phossy jaw, given its name after workers in match factories working with white phosphorus developed osteonecrosis of the jaw.

After some years of exposure they could get infected from the poisonous phosphorus and get a disease called "Phossy jaw" and could lose their teeth.

In addition, exposure to the vapours gave match workers a severe necrosis of the bones of the jaw, the infamous "phossy jaw".

The condition is similar to phossy jaw, an osteoporitic and osteonecrotic illness of matchgirls, brought on by phosphorus ingestion and absorption.

They were influential in fighting against the dreadful disease known as Phossy jaw which was caused by white phosphorus used in the manufacture of the early matches.

This practice resulted in the ingestion of radium, which caused serious jaw-bone degeneration and malignancy and other dental diseases reminiscent of phossy jaw.

This had been a long time goal for chemical investigators in the industrial world, white phosphorus' necessity in match-making being the cause of the industrial disease called "phossy jaw."

Phossy jaw, formally phosphorus necrosis of the jaw, is an occupational disease of those who work with white phosphorus, also known as yellow phosphorus, without proper safeguards.

Unfortunately, those involved in the manufacture of the new phosphorus matches were afflicted with phossy jaw and other bone disorders, and there was enough white phosphorus in one pack to kill a person.

The strike was prompted by the poor working conditions in the match factory, including fourteen hour work days, poor pay, excessive fines, and the severe health complications of working with yellow (or white) phosphorus, such as phossy jaw.

Compare me with one of those rascals who disseminate phossy jaw and lead poisons, compare me with a millionaire who runs a music hall with an eye to feminine talent, or an underwriter, or the common stockbroker.

He is clothed in the lives of bent and thwarted weavers, his Way is lit by phossy jaw, he eats from lead-glazed crockery--all his ways are paved with the lives of men.... Think of the chubby, comfortable creature!

Concern over phossy jaw contributed to the London matchgirls strike of 1888, and although this strike did not end the use of white phosphorus, William Booth and the Salvation Army opened a match-making factory in 1891 which used the much safer, though more expensive, red phosphorus.

The low wages that were reported at the meetings, the phossy jaw which was described and occasionally exhibited, the appearance of the girls themselves I did not, curiously enough, in any wise connect with what was called the labor movement, nor did I understand the efforts of the London trades-unionists, concerning whom I held the vaguest notions.
