Chemical Maximum Maximum
Compared with Compared with
8 hr TWA 15 min STEL
Ethanol 2.25% 0.07%
PGME Acetate 0.04% 0.00%
Toluene 4.28% 0.16%
Ethylbenzene 2.18% 0.15%
o/m/p – Xylene 6.45% 0.29%
n-Butyl Acetate 1.48% 0.04%
Trimethylbenzene 1.90% 0.07%
Butan 1-ol 1.90% 0.17%

As can be seen above, the highest exposure is 6.45% of the government maximum 8 hour

exposure limit and 0.29% of the 15 minute exposure limit. (Xylene is a chemical used in
paint, Toluene is found in paint and fuel).

These percentages are very low and we consider the risk to health of working near pumps
to be low. It should be noted however that vapours are present and may be concentrated
in areas such as pits and gullies.

International Occupational Health Limited (IOH) have provided the following as a
conclusion: “The data measured and presented shows very low levels of exposure.
Clearly, this is dependant upon the amount of work, the degree of enclosure (i.e. the more
enclosed the higher exposure will be) and the environmental factors (i.e. wind
speed/direction, etc.)”.

A full copy of the report is available from the office on request.

“let’s make sure that we continue to make our sites THE SAFEST by helping ourselves, our colleagues,
our customers and even our competitors by improving training, helping where necessary and addressing
any issues of concern there and then”
