Hazard Recognition

Ventilation may be deficient in confined spaces, facilities failing to provide adequate maintenance of ventilation equipment, facilities operated to maximize energy conservation, windowless areas, and areas with high occupant densities. The following references aid in recognizing and evaluating hazards associated with ventilation in the workplace.

  • Field Operations Manual (FOM). OSHA Directive CPL 02-00-163, (September 13, 2019).
  • OSHA Technical Manual (OTM). OSHA Directive TED 01-00-015 [TED 1-0.15A], (January 20, 1999). Several portions of the OTM include ventilation as part of the evaluation process:
  • Industrial Ventilation: A Manual of Recommended Practice, 25th Edition. American Conference of Governmental Industrial Hygienists (ACGIH), (2004). Provides research data and information on the design, maintenance, and evaluation of industrial exhaust ventilation systems, including basic ventilation principles and sample calculations.
