Mau uso da técnica - versão química

Pesquisando recentemente sobre a produção de sabão em pó, fiquei sabendo sobre a polêmica que existe sobre o lauril sulfato éter de sódio (vulgo sodium laureth sulfate), diversas pessoas dizem que ele poderia dar câncer mas os especialistas (incluindo o FDA) garantem que não pega nada.

Achei, no entanto, esta pérola:

"A LITTLE MORE NEWS.... if you think the ingredients in your personal products are safe, then why did this happen at a shampoo factory.. 7/14/99

*** 5,000 evacuated in Iowa due to spill

IOWA CITY, Iowa (AP) - About 5,000 people were evacuated Tuesday from the city's southeast side when a corrosive chemical spilled while being unloaded at a factory that makes shampoo and toothpaste. About a gallon of the chemical, called Chlorosulfonic Acid or CSA, spilled while being piped from a rail car into a storage tank at a Procter & Gamble Co. factory. The spilled acid formed a vaporous cloud, which began drifting on the wind. "They can harm you if you inhale them or just come into contact with your skin," said Iowa City Fire Marshal Roger Jensen. Two police officers exposed to the vapor were checked out at a hospital and released. There were no other injuries, Jensen said. P&G spokesman Mike McCleary said the spill occurred about 10 a.m. when a valve on the unloading equipment failed."

Hum, realmente eles têm um ponto. Se o xampu é seguro, por que esvaziaram a fábrica? Será que as fábricas de papel também são um perigo já que pode vazar soda cáustica a qualquer momento? Não devemos reduzir o consumo de papel sulfite antes que nossos dedos sejam corroídos e os cotocos caiam?

Ah, façam-me o favor...
