Flavorings-Related Lung Disease
There are currently no specific OSHA standards for occupational exposure to butter-flavoring, diacetyl, or 2,3-pentanedione. However, OSHA standards regulating all workplaces offer protection to workers exposed to these substances.
This section highlights OSHA standards and directives (instruction to OSHA staff) related to occupational exposure to butter-flavoring or the chemical diacetyl.
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".
