Links to OSHA & NFPA Requirements

Taken from OSHA's website, the following information and links are beneficial in researching combustible dust as it relates to you business.

OSHA

Section 5(a)(1) of the OSH Act, often referred to as the General Duty Clause, requires employers to "furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees". Section 5(a)(2) requires employers to "comply with occupational safety and health standards promulgated under this Act".
Note: Twenty-four states, Puerto Rico and the Virgin Islands haveOSHA-approved State Plans and have adopted their own standards and enforcement policies. For the most part, these States adopt standards that are identical to Federal OSHA. However, some States have adopted different standards applicable to this industry or may have different enforcement policies.

Highlighted Standards
General Industry (29 CFR 1910)
Directives National Consensus
Note: These are NOT OSHA regulations. However, they do provide guidance from their originating organizations related to worker protection.
National Fire Prevention Association (NFPA)
  • Codes and Standards. National Fire Prevention Association (NFPA) develops, publishes, and disseminates more than 300 consensus codes and standards intended to minimize the possibility and effects of fire and other risks. Virtually every building, process, service, design, and installation in society today is affected by NFPA documents.
    • 61, Standard for the Prevention of Fires and Dust Explosions in Agricultural and Food Processing Facilities
    • 484, Standard for Combustible Metals
    • 654, Standard for the Prevention of Fires and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids
    • 655, Standard for Prevention of Sulfur Fires and Explosions
    • 664, Standard for the Prevention of Fires and Explosions in Wood Processing and Woodworking Facilities
Consensus Standards and the General Duty Clause

Using Consensus standards to support a 5(a)(1) Citation:
A consensus standard can be used to show "industry recognition" of a hazard. However, the hazard must be recognized in the employers' industry, not an industry other than the employers' industry.

Section 5(a)(1):
  • is not used to enforce "should" standards.
  • is not used to required abatement methods not required by a specific standard.
  • is not normally used to cover categories of hazards exempted by an OSHA standard.
Background
Section 5(a)(1):
  • Each employer shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employee;
     
  • The general duty provisions can only be used where there is no standard that applies to the particular hazard involved.
Evaluation of Potential 5(a)(1) situations:
  • Employer failed to keep workplace free of hazards to which employees of that employer were exposed.
    • Must involve a serious hazard and employee exposure
    • Does not specify a particular abatement method - only that the employer keeps the workplace free of serious hazards by any feasible and effective means.
    • The hazard must be reasonably foreseeable.
  • The hazard was recognized.
    • Industry recognition
    • Employer recognition
    • Common-sense recognition
  • The hazard caused or was likely to cause death or serious physical harm.
  • Feasible means to correct the hazard were available.
