GENERAL CRITERIA. Installing engineering controls is the preferred
method of controlling hazardous processes as specified in 29 CFR 1910.1000(e), Air
Contaminants and OPNAVINST 5100.23, Navy Occupational Safety and Health
Program Manual. Properly designed industrial ventilation systems are the most
common form of engineering controls.
COORDINATION. Form a project design team to direct the design of
industrial ventilation projects. Include in the design team representatives from:
Effected industrial shop.
Health and safety office.
Cognizant Regional Engineering Office (REO) (for example: Navy
Engineering Field Division, Army Corps of Engineers Division, and Air
Force major command engineering office). The REO representative
establishes a design team and acts as the team leader in all cases, except
when the cognizant REO grants a variance.
Industrial hygiene and safety offices.
NOTE U.S. NAVY: BUMED or activity IH. Use Naval Environmental
Health Center as a back-up.
System command program manager (where applicable).
System safety engineer.
DESIGN PROCEDURE. Refer to the ACGIH IV Manual, Industrial
Ventilation; A Manual of Recommended Practice
5, "Exhaust System Design
Procedure," for system design calculations. Design all industrial ventilation systems in
accordance with paragraphs 2-3.1 through 2-3.8.
Step 1. Identify all significant contaminant sources that require ventilation
control. Request the local industrial hygiene office to provide a source characterization
with area diagrams of the contaminant sources, and employee work areas. Also,
