When workers are transport hazardous chemicals, handling them or processing them accidents are sometimes likely to happen and when this happens some of these people are exposed to great danger, something has to be done about it. There have been reports that some workers have rushed to clean chemical spills without knowledge that some of these chemicals have really high toxic levels.
Some countries in an effort to protect their workers and environments from the hazards of these chemicals have come up with a system of classification to help put things in the clear. These classifications have not been developed in some countries which is still a big problem because they are not providing a safe environment for their workers to work in.
When purchasing these chemicals it is important that those selling them disclose the presence of toxins and clearly explain how hazardous they are so that those buying them can handle them accordingly. This trade was hindered by the fact that a lot of nations had their own classifications while others did not hence it is was hard to get them all to agree on one.
All countries realized that what they wanted to benefit from each other from this trade so a unified system of classification that identified chemicals and levels of hazards was developed. This was not an easy task however, it involved the development of GHS safety data sheets that relied on the research of all the classifications made by all individual countries then eliminating all the differences while still maintaining the protection that each country intended.
The safety data sheets took into account the hazardous properties of all single chemicals as well as their reactivity with water, other chemicals and air, it also documented the impacts caused when these chemicals are released into the environment. One problem that SDS had when documenting these hazardous chemicals is trying to exclude all the confidential information of protected formulas.
Since the GHS has done its job to set defined rules it is upon companies officials to ensure that all their workers are aware of them and that they are properly trained to deal with the chemicals. It is also a requirement for these companies to provide all the SDS in printed document so that workers or people dealing with them can access them when required.
For further convenience you can have the information in electronic forms so that you can send it to the portable devices that most workers have, this way they can have as much exposure to it as possible. More caution will be taken if you have all your chemicals well labelled as hazardous, so make a point to have your company do that for all the chemicals that you deal with.
