THERE IS probably no single course in “laboratory safety or chemical safety” at your college or
university. Why not? Chemistry curricula have developed over many decades with a focus on the main
topics of chemistry: organic, inorganic, physical chemistry, analytical chemistry, and (more recently)
biochemistry. For decades, the topic of chemical safety was included at the margins of lab courses,
mostly taught in a small way as a footnote to various lab experiments and procedures. Some chemists and
chemistry teachers were aware of the importance of safety, while many were not.
Clean air is a basic requirement of life. The quality of air inside homes, offices,
schools, day care centres, public buildings, health care facilities or other private
and public buildings where people spend a large part of their life is an essential
determinant of healthy life and people’s well-being. Hazardous substances emit-
ted from buildings, construction materials and indoor equipment or due to hu-
man activities indoors, such as combustion of fuels for cooking or heating, lead
to a broad range of health problems and may even be fatal....
Within the overall transport process, attenuation processes may cause movement of the
chemical to differ from that of the bulk flowing groundwater, for example dispersion, sorption
and chemical or biological degradation of the chemical. Such attenuation processes
potentially act to mitigate the impact of chemicals and are a function of both the specific
chemical and geologic domain. Indeed, attenuation may vary significantly between individual
chemicals and within different geological settings.
The air pollution accumulating in the interior
of automobiles consists almost exclusively of gaso-
line and diesel exhaust. This toxic soup of gases,
aerosols, and microscopic particles includes ben-
zene (a known carcinogen), carbon monoxide
(which interferes with the bloods ability to trans-
port oxygen), particulate matter (which studies
have associated with increased death rates), and a
host of other hazardous chemicals.
In assembly, the principle impact relates to the use of glues and adhesives. The main issue
associated with the use of adhesives is related to the solvent content of glue and the
consequent emissions of VOCs, although other hazardous substances may also be present in
Therefore, in order to minimise the negative environmental impacts of certain glues, criteria
shall be set to limit the content of VOCs in adhesives and the content of hazardous additives.
With the increasing complexity of modern medicine, we now have literally
thousands of possible investigative techniques at our disposal. We are able
to examine our patient’s serum and every other body fluid down to the
level of individual nucleotides, as well as being able to perform precise
imaging through CT, MRI and other imaging technologies. The problem we
have all faced, especially as senior medical students or junior doctors is:
which test should we use in a given setting? What hazards are associated
with the tests?...
New cases of active pulmonary tuberculosis
admitted to our critical care unit from January 1999
to January 2006 were identified. Data were collected
retrospectively from medical records including
demographics, clinical presentation, number of sputum
samples, therapy provided and patient outcome.
Setting: Data were collected from the ICU database and
microbiology laboratory records.
Patients and participants: Thirty-three patients were
diagnosed with active pulmonary tuberculosis. Age
was 63±17, and 60.7% were males.
The toxicity or carcinogenicity of each reagent used in this method has not been
precisely defined; however, each chemical compound should be treated as a potential
health hazard. From this viewpoint, exposure to these chemicals must be reduced to
the lowest possible level by whatever means available. The laboratory is responsible
for maintaining a current awareness file of OSHA regulations regarding the safe
handling of the chemicals specified in this method.
