Factor
How to avoid / Measure
Intake and Exhaust of
Hazardous Gas/Substance
Exhaust of toxic gas, combustion gas, flammable gas,
corrosive gas, and explosive gas is extremely
dangerous. Do not exhaust any gas with these
properties.
You get injured by touching
pump oil, pump, products, and
aspiration materials which have
become toxic at the time of
inspection/disposal.
(1) Wear protective equipment to toxic materials you
use, before starting work, such as inspection.
(2) At the time of overhaul/disposal, please ask a
professional contractor for the waste disposal to
detoxify.
(3) Ask a waste disposal company with an
administrative approval to dispose of the product.
You get injured by
ignition/explosion due to residual
gas or products.
If combustion/flammable/explosive gas is sucked in
the vacuum pump, it is extremely dangerous because
the residual gas or products may cause
ignition/explosion not only in operation but also after a
stop. Do not exhaust any gas with these properties.
