Hydrofluoric acid fatality

A recent accident in Perth highlighted just how hazardous this acid can be and it is worth recounting for the benefit of any hygienists whose work may involve advising others who use this substance.
On November 12, a 37 year old man died in the Intensive Care Unit of Fremantle Hospital after who accidentally splashed about 100 ml of a 70% solution on his right leg on October 28. It was estimated that the extent of the spill covered about 10% of his total body area. The individual was working as a technician in a small palynology laboratory, which was attached to a private residence. HF is used in the industry to digest silicates in ore samples. The victim attempted to remove the spill from his clothing at the time by hosing himself down with a hose attached to a sink in the laboratory; he then ran from the laboratory to the swimming pool in the garden, and he remained in the pool until the ambulance arrived within the hour. At the time he appeared confused, possibly as a result of shock.
The following week his right leg was amputated, however despite this, the individual eventually succumbed to the toxic effects of the hydrofluoric acid 2 weeks after the initial spill. There are a number of points that need to be emphasised as a result of this, which are relevant to all users of HF:
First, always ensure that the users are aware of just how hazardous this substance is. I have been surprised at how many people including hygienists, appeared surprised by the consequence of this accident. Always make sure a Material Safety Data Sheet is available.
Second, always ensure that adequate precautions are taken. In this context, "adequate" means full protective clothing, including gloves, visor, apron, boots as an absolute minimum; it means also purpose built handling facilities, such as fume cupboards and it also means providing calcium gluconate as a treatment agent, to be available at hand. There is at least one case history documented of an individual surviving a splash to 22% of his body surface area, as a consequence of immediate treatment with calcium gluconate.
Further details on the above incident will be available as a Significant Incident Summary from the Department of Occupational Health, Safety and Welfare of Australia, tel. (08) 9327-8777.

In addition to the recommendations above and overleaf, the following recommendations are made:

• The storage and location of hydrofluoric acid solutions should be secure to prevent usage by untrained personnel
• Calcium carbonate chips should be available for clean up of spillages. Contaminated chips should then be placed into a container for disposal by a chemical waste contractor
• In cases of exposure where medical attention is sought, the treating doctor must be informed that hydrofluoric acid is involved in the corrosive burn
• Personnel using dilute hydrofluoric acid solutions should be made aware that there may be no initial burning sensation or pain associated with contact, but that serious delayed burns can still occur. Therefore, treatment must still be given immediately after contact

Dear Iggle,

We've got some good news to share.

One year ago today we released The Story of Cosmetics to build support for national legislation to regulate personal care product ingredients.

For years, the multi-billion dollar cosmetics industry had been largely left alone to decide what was safe to put in their products. You know, things like lead in lipstick, neurotoxins in body spray and carcinogens in baby wash.

Now, one year later our partners at the Campaign for Safe Cosmetics are making significant progress.

One big reason the Campaign is more hopeful than ever about our chances for getting this serious public health threat addressed is the increasing support for reform coming from this country's community of small personal care product companies.

We've posted a blog today about the incredible work the Campaign has done to incorporate the concerns of this community-among the best actors in the market already-into the newly introduced Safe Cosmetics Act of 2011.

This groundbreaking bill would eliminate the most harmful chemicals from cosmetics (as Europe already does!), and ensure that personal care products are reviewed for safety before they end up on store shelves.

If that sounds reasonable to you, why not help us celebrate The Story of Cosmetics' first birthday by sharing The Story of Cosmetics with your friends and family and then letting your elected officials know that you support the Safe Cosmetics Act.

You can watch and share the movie on our site. Let's get that viewcount up to 1 million!

Then make sure to visit the Campaign for Safe Cosmetics site to send a message to Congress.

Thanks for your support and for all you do to make this a better world.

Onward!

hydrogen oxygen tax

Due to the amount of added water in general food stuffs by the major stores in Australia the government will introduce a excess water tax for the major supermarkets. I just cooked eggs and bacon and had to boil off the water before it would give that nice crispy flovor of the bacon adding an extra fuel bill, to boil off the water. We Australians need a pay rise to also pay for the water we do not drink from the water supply. The water authorities have to increase the price of water to cover the costs of the low water consuption. It is good that I was a commercial diver as wearing a snorkel and goggles when going to the meat section brings back old memories. When will it ever end.....

slaughter of animals

I worked as a slaughter man here in Australia. One day a sheep was not killed and was sent up the chain and was being skinned alive and when it got to me. I stopped the chain and killed the animal. To this day I still have nightmares because of the brutality and cruelty that was inflicted on this animal and me. Mine only being emotional. Don't throw stones at other countries when it is done here....Nuff said.
