An Understanding of Science Can Lead to a Better Understanding of Occupational Health and Safety.
An introduction to Occupational Health and Safety
In the first six months of 2012, the National Statistics Office reported that 1,482 workers suffered work related injuries in Malta, five of which resulted in death. (National Statistics Office, 2012) Occupational Health & Safety (OHS) aims at protecting the physical, social and psychological wellbeing of people from illness resulting from the materials, processes or procedures used in their work. (Coppеe, 2005). So how does an understanding of science lead to a better understanding of OHS?
What is Science?
According to Oxford’s dictionary, “science encompasses the systematic study of the structure and behaviour of the physical and natural world…” (Oxford Dictionaries, 2006) Everything we hear, see, smell, taste, and touch involves intricate series of chemical reactions and interactions in our body; not to mention that we owe our very existence to a multitude of chemical reactions. In a nutshell, chemistry is the scientific study of matter and the changes it can undergo. (Brady & Senese, 2007)
The Chemical Aspect
Although there are countless types of matter all around us, this complexity is composed of various combinations of 118 elements, systematically organised in what is called a periodic table depending on common properties, such as number of electrons in the outer shell and the elements’ amount of shells. (Puddephatt & Monaghan, 1986) The reactivity of an element depends directly on the completeness of its outer electron shell. For example, if an element in the far right column, known as noble gases, has an atomic mass of 10, split in 2 electrons in the inner and 8 in the outer shell, this makes it complete and thus non-reactive. However, if we have elements that have an incomplete outer shell, such as in group 1 and 7 we know that these are highly reactive because they need to lose or gain an electron to reach a stable state. (Fischer & Peters, 1970) Elements and chemical reactions are not confined to a

    The periodic table is composed of eighteen columns and seven horizontal rows, with two additional rows underneath. There is grand total of 112 elements in the periodic table, each of which is placed in a designated spot on the table and cannot be moved. Different areas on the table have elements that are made of different components. Elements that are in the same column are more similar than elements in the same horizontal row. Seventy five percent of the table is made up of metals, and a couple of the columns on the right of the table have gases. There are only two elements that are liquids- mercury and bromine. Column 1 contains the alkali metals, which suddenly combust when exposed to air or water. Columns 3-12 are the transition metals, which contain heavier atoms, which are more flexible in how they organize their electrons. Column 17 is made up of the more reactive gases- the halogens. The noble gases are in column 18. The electrons are the most significant part of an atom. When atoms don’t have the sufficient number of electrons they need in their outer level, they will do whatever they can to get the number they need. The number of protons an atom has is its atomic number. The atomic number plus the number of neutrons the atom has is the atom’s atomic weight.…

    Following accidents and allegations, it has been said that health and safety are not being taken serious in Britain’s Scientific Workplaces, there are many organisations that keep a check on laboratories to make sure that they are continuing to maintain the standards that are required for that particular scientific area and that all the staff members who work there are not being put at risk. The aims of these regulations are to ensure safe working practices and environmental protection. These regulations can be achieved by the correct use of the buildings, machinery and equipment as well as use of energy and water.…

    1. I just returned home from being interviewed for a new public television program on the mystery of matter and the search for the elements. It was very gratifying to see how keen the film-makers were on understanding precisely how Mendeleev arrived at his famous first periodic table of 1869. This in turn meant that I had to thoroughly review the literature on this particular historical episode, which will form the basis of this blog.…
