Watch the below video to identify general working environment requirements then study the text in this page and the following pages and refer to sources of
information recommended in the module then assess your understanding by solving the end of module quiz
2.1 Ventilation:
Workplaces need to be adequately ventilated. Fresh, clean air should be drawn
from a source outside the workplace, uncontaminated by discharges from flues,
chimneys or other process outlets, and be circulated through the workrooms.
Ventilation should also remove and dilute warm, humid air and provide air
movement which gives a sense of freshness without causing a draught.
If the workplace contains process or heating equipment or other sources of dust, fumes
or vapours, more fresh air will be needed to provide adequate ventilation.
Windows or other openings may provide sufficient ventilation but, where necessary,
mechanical ventilation systems should be provided and regularly maintained.
2.2 Temperatures in indoor workplaces:
Environmental factors (such as humidity and sources of heat in the workplace) combine
with personal factors (such as the clothing a worker is wearing and how physically
demanding their work is) to influence what is called someone’s ‘thermal comfort’.
