Safety sheets

The vapour pressure of a liquid provides an essential safety parameter and it is mandatory that safety sheets contain these values (when they are known). This parameter is taken into account in some classification methods of inflammability risk. It enables one to determine the equilibrium vapour concentration of a liquid in air. This concentration can then be used to ascertain whether a working environment presents an inflammability risk (by reference to the inflammability limits) or a toxicity hazard (by comparison with the exposure values).

LEL is the most important of the two limits. It is mostly useful when inflammable substances are handled in confined spaces (reservoirs, painting cabins, ovens etc). Detaiis of limits of inflammability are kept by chemical substance manufacturers who are required to mention them on safety sheets that have to be put at clients disposal. When compared with the equilibrium concentration determined as indicated before, LEL aiiows determination of whether a working environment presents a risk of explosion in the presence of a source of ignition. 

Safety and risk factors evaluate approximately the speed at which a toxic substance reaches a toxic vapour concentration in air. An accurate way to do this would be to know the vapourisation speed for this substance and the air renewal rate of the room in which it is handled. This is why regulations recommend measurement of the vapourisation speed for a particular substance and include it in safety sheets. One can hardly use this figure since it is rarely mentioned. The only substances which were subjected to such measurements are the most commonly used although these figures only are remotely linked to the real conditions. So it was decided to suggest a method derived from the vapour pressure of the substance, which is a factor the vapourisation speed depends on precisely. 

Health and Safety Data Sheet This document is required to provide anyone who comes into contact with the material with sufficient information needed to react to a spillage or breakage. The labelling and health and safety sheet regulations are not yet consistent through out the world and at the time of writing there is no way to label a product so that it conforms to US, Canadian, European and Australian requirements The Safety data sheet issue is less confused, the U S OSHA and EU forms of the so called material safety data sheet are moving to conform with an I SO Standard.

Safety precautions Before the experiment is carried out, Sect. 2.2.5 must be read as well as the material safety sheets (MSDS) for all chemicals and products used. Due to the high temperature of the oil bath needed in this experiment, special care has to be taken and one has to work in a closed hood. In addition, a safety shield is required when working under high vacuum. 

Most biocide products continue to be sold under some form of brand name, which often does not properly describe the active materials contained (although the precise active chemicals are normally listed in the health and safety sheets). However, increasingly around the world, it is becoming necessary to provide all relevant information on the product label, in an approved manner, and for the company whose name appears on the label to be properly subregistered with the relevant authorities. (This has been required in the United States for many years.) This original registration and... 

Laboratory safety, as discussed below. Consult the Material Data Safety Sheets (MDSS) for information regarding hazards - carcinogens, flammability, corrosiveness, etc. - associated with chemicals used in the experiments. 

However, this is an example of an essential oil in which the minor components are of great significance it contains a furocoumarin called bergaptene (0.2-0.5%), which is a phototoxic compound and needs to be used with caution. Many oils have it removed and are called FCF (furocoumarin-free) oils, even though this is technically a rectification of the whole oil. This is discussed under safety in Chapter 8. The odour of this oil is also influenced by the presence of trace components guaienol, spathulenol, nerolidol, farnesol and (i-sinensal. Box 7.8 shows safety data for bergamot oil and Box 7.9 shows a material data safety sheet.

A gas data and safety sheet for carbonyl difluoride has been produced by the British Compressed Gases Association [277] and the compound is described in the Matheson publication, "Guide to safe handling of compressed gases [1347], and the ACGIH Documentation of the Threshold Limit Values for Substances in Workroom Air [38,39]. 

RSDL. In 1995, the Canadian Defense Research Establishment at Ottawa and Suffield developed and patented a liquid skin decontaminant for CWA exposure named RSDL. RSDL is a formulation of potassium 2,3-butanedione monoxime (as free oxime and potassium salt) in a solvent of polyethylene glycol monomethylether (MPEG) of 550 nominal molecular weight with 10% w/w water (pH 10.6) (Sabourin et al., 2001 Bide et al., 2005 Material Data Safety Sheet, 2006). 

Diphoterine. Diphoterine is a French decontamination product inaniifactLired by Prevor Laboratory (Vlamondois, France) (Material Data and Safety Sheet, 2007). Unlike the other decontaminating systems discussed, Diphoterine was also designed to be used in decontaminating the eyes. It is supplied as an odorless, colorless, sterile solution in water (pH 7.4). It is classified as a slight dermal irritant (Jones et al., 1987) but a nonirritant in the eye as tested in the rabbit model (Clouzeau and Read 1990).
