Phạm vi áp dụng / Scope of standard

This Standard establishes minimum requirements for the
commissioning, design, specification, construction, and
installation of fixed industrial local exhaust ventilation (LEV)
systems used for the reduction and prevention of employee exposure
to harmful airborne substances in the industrial environment.

The Standard also establishes fundamental requirements for the
management, operation, maintenance, and testing of LEV systems to
assure satisfactory performance over the life of the system.

The Standard also describes basic requirements for replacing air
exhausted from the space.

The Standard does not cover:

• ventilation for comfort,

• air moving systems which are part of an industrial
process,

• paint booths not used primarily for employee protection,
or

• energy conservation

except when they also impact or apply to airborne contaminant
control for employee protection.

Where Standard provisions are in conflict, the more stringent
shall apply.
