As a flavor and/or fragrance manufacturer, you understand the importance of not just preventing employee exposure to hazardous fumes, but you recognize a need to control odor pollution in the surroundings of your facilities as well. At production facilities throughout the area we work to prevent emissions of unpleasant odors, by designing, installing and implementing ventilation and dust collection systems for employee protection, while equipping those systems with deodorizing technologies where necessary for the community.
Occupational Exposure to Flavoring Substances: Health Effects and Hazard Control

OSHA Recommendations: Engineering and Work Practice Controls
… important engineering control measures include use of local exhaust ventilation to remove contaminants,…
Exposure of employees to inhalation, ingestion, skin absorption, or contact with any material or substance at a concentration above those specified in the “Threshold Limit Values of Airborne Contaminants for 1970” of the American Conference of Governmental Industrial Hygienists, shall be avoided
To achieve compliance with paragraph (a) of this section, administrative or engineering controls must first be implemented..

Although there is no federal standard for the flavor manufacturing industry specifically, the industry is subject to a number of OSHA regulatory requirements under the General Duty Clause. OSHA has clearly spelled out in its National Emphasis Program for flavor manufacturing that the agency is willing to rely heavily on the General Duty Clause of the Occupational Safety and Health Act (Section 5(a)(1)) for broad authority over flavor manufacturing in general, and specifically as it relates to exposure to diacetyl.
A dust collection system is an air quality improvement system that operates by safely removing particulate matter from the air. The basic function of dust collection systems is to capture, convey and collect. The dust is captured using custom designed hoods (fixed point) or extraction arms (to cover a variable area) to catch dust at the source. Production machines will often have a port through which a duct can be connected directly. Dust is conveyed through a ducting system, that must be properly sized and branched to maintain a consistent minimum air velocity to keep the dust in suspension for delivery to the collection area. Duct that is too large will slow the particulate as it travels causing settling in the duct. Duct that is too small will be noisy and may cause static pressure to go up, thus reducing the effectiveness of the fan that is extracting the particulate.
OSHA: “Any combustible material can burn rapidly when in a finely divided form. If such a dust is suspended in air in the right concentration, under certain conditions, it can become explosible. Even materials that do not burn in larger pieces, given the proper conditions, can be explosible in dust form.”
According to the National Grain and Feed Association in their “Update on OSHA and NFPA Combustible Dust Standards”: “A Lack of a Combustible Dust Standard is not stopping OSHA-
- The “general duty clause” is Section 5(a)(1) of the Occupational Safety and Health Act of 1970.
- Each employer shall furnish to each of his employees a place of employment which is free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees.
- The general duty clause is basically an all-encompassing regulation that OSHA uses if there is a perceived violation that is NOT covered by any other regulation. OSHA uses NFPA standards to justify citations.”
NFPA 61 Standard for the Prevention of Fires and Dust Explosions in Agricultural and Food Processing Plants will be quoted under the OSHA’s general duty clause as the reason for the violation.
The food industry deals with some extremely explosive dusts which include, but are not limited to: sugars, spices, starches, flours, feed and grains. Because of this, a properly installed dust collection system by Clean Air Company will not only eliminate dust, but it will meet the most stringent NFPA standards for fire prevention.
