Whether or not we are at home or at work, chemicals are around us every where. 本次會議目的是強調(diào)我們?nèi)粘９ぷ髦卸紩龅降臐撛趩栴}。無論我們在家還是在工作，化學(xué)物質(zhì)都與我們息息相關(guān)。 How we prevent contact with them and subsequent harm can be very simple. 預(yù)防與化學(xué)物質(zhì)的接觸及其危害后果是非常簡單的。 Hopefully at the end of the session we will be more aware of the potential problems posed by them and also we just may be able to apply what is needed to be a little safer today than we were when we came into the room. 希望在會議結(jié)束的時候，我們能夠比開始的時候更加了解化學(xué)物質(zhì)的潛在危害，同時在今后的工作中也能夠更加安全的操作。 Fine Chemicals Page 2 Date StandardPresentationengl The Fine Art of Fine Chemicals174。 FCFEA / Preventing Exposure to Chemicals What is it that is a poison ? 什么是有毒物質(zhì)？ All things are poison and none without poison. Only the dose determines that a thing is poison. 任何物質(zhì)都是有毒的，沒有什么是無毒的。只有不同的劑量來確定一種物質(zhì)是有毒物質(zhì)。 Paracelsus 1538.

Example, a solid block of hardwood timber is hardly going to cause a problem. However the same block being planed or sanded creates a much greater hazard. The creation of wood dust poses a serious health hazard. 危害 一種物質(zhì)的固有屬性。例如，一塊實心硬木料很少會導(dǎo)致任何問題。然而同樣的木塊，經(jīng)過刨平或者鋪沙，就會產(chǎn)生很大的危害。木料灰塵的產(chǎn)生可導(dǎo)致嚴(yán)重的健康危害。 Risk The form of a material is important in determining the risk to health from that material. No matter how toxic a substance is, if it cannot gain entry or onto the body it cannot have a toxic effect. The result in toxic effect is zero. 危險 一種物質(zhì)的組成對于確定它對于健康的危險是非常重要的。無論一種物質(zhì)的毒性有多大，如果它不能進入人體或與人體接觸，那么它就不能構(gòu)成毒害。毒性作用為零。 Fine Chemicals Page 4 Date StandardPresentationengl The Fine Art of Fine Chemicals174。 FCFEA / Preventing exposure to chemicals預(yù)防化學(xué)物質(zhì)暴露 Contaminants污染物 Gas Nitrogen, Cyanide, Carbon Dioxide, Chlorine. 氣體 氮氣，氰化物，二氧化碳，氯 Vapour Solvent vapour, process vapour. 蒸汽 溶劑蒸汽，工藝蒸汽 Dust Wood dust, household dust.
