• Employers must provide some level of industrial hygiene in their workplaces.
• Compliance may include: Using labels to warn of exposure hazards, monitoring employee exposure levels, providing PPE or other control measures to protects employees from hazards, and more.

Employers are required to implement some element of an industrial hygiene or occupational health program. The Occupational Safety and Health (OSH) Act establishes the criteria the employer will use in protecting employees against health hazards and harmful materials.

Generally, the guidelines set the standards for compliance in the following areas:

• Using labels and markings to warn of exposure hazards.
• Prescribing suitable protection equipment and control or technological procedures to be used against hazards.
• Monitoring or measuring employee exposure levels.
• Maintaining accurate records of employee exposures to potentially toxic materials or harmful physical agents that are required to be monitored.
• Notifying any employee who has been or is being exposed to toxic materials or harmful physical agents in concentrations or at level that exceed those prescribed by any standard.
• Informing any employee who is being exposed of the corrective action being taken.

The Occupational Safety and Health Administration (OSHA) regulations deal with air contaminants (gases, fumes, vapors, dusts, and mists), noise, and ionizing radiation.
