HSE guidance (HSG
258, published to
‘improve the
coverage and
effectiveness of LEV’,
recommends
(paragraph 229)
airflow indicators are
fitted at all extraction
points. Indicators
safeguard operators
from serious health risks they may
unwittingly run when using extraction
that is no longer performing within
the design parameters.
Nederman Aftersales will install
airflow indicators onto any system –
and not just onto Nederman
equipment. Gary
Keene, projects
director, says: “The
push button lights
green or red. Red
means there is
insufficient airflow
and further action
should be taken.”
The compact
wall-mounted units
can be mounted virtually anywhere
and no electrical power is needed.
