Work Activities
Approximately 70% of painting operations involve painting with water
based paints in well ventilated areas and do not present a hazard to
workers from solvents.
Painting using this formulation makes up approximately 20% of painting
operations.
This is most likely the most hazardous operation conducted by painters.
Painting in non-air-conditioned spaces place workers at risk for heat
injuries

While it is understood that the
“smell” of the varnish can be quite
strong it should be noted that the
solvents used in these materials
generally have a very low odor
threshold which is well below the
action level which is generally 50%
of the permissible exposure level
for these solvents.
Continue emphasis on heat injuries
whenever safety stand downs,
events, tool box talks etc.. are
planned. Ensure that drinking
water is always available for crews
working in heat stress conditions.
Ensure that sub contractors receive
training on the Heat Stress Program
observed at the Sembawang
Compound including the use of
colored flags.
Please refer to the chart provided

Activity Level
Discretion is required when planning heavy exercise for acclimatized personnel.
Strenuous exercise and activity for new and un-acclimatized personnel during the first 30 days of heat exposure.
Strenuous exercise should be curtailed for personnel with less than 12 weeks of training in hot weather.
Physical training and exercise should be curtailed for all personnel (operational commitments excluded).
Heat stroke likelihood is high under conditions of high exertion.
