    Study Notes

    Occupational Safety and Health Act

    • The Occupational Safety and Health Act (OSHA) covers most private sector employers and their employees in the United States
    • The Act requires employers to furnish employees with a workplace free from recognized hazards that are causing and likely to cause death or serious physical harm.
    • The Act also establishes standards for workplace safety and health, including a “General Duty Clause” requiring employers to provide a safe and healthy work environment for their workers
    • OSHA's mission is to ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance.

    Horizontal and Vertical Standards

    • Horizontal standards apply to all industries
    • Vertical standards apply to specific industries

    General Duty Clause

    • This requires employers to provide a safe and healthy work environment for their workers, even if there are no specific OSHA standards for the hazards present in the workplace.

    Employer Rights and Responsibilities

    • Employers have the right to challenge OSHA citations and penalties
    • Employers have the right to request an informal conference with OSHA to discuss the citation and penalty
    • Employers are responsible for providing a safe and healthy work environment for their workers
    • Employers are responsible for complying with OSHA standards

    Employee Rights and Responsibilities

    • Employees have the right to report unsafe working conditions to OSHA.
    • Employees have the right to request OSHA inspections of their workplace.
    • Employees are responsible for following safe work practices
    • Employees have the right to seek access to information on hazardous materials and to receive training on hazard recognition and control.

    Communications and Correspondence with OSHA

    • Employers are required to provide OSHA with certain information, such as records of workplace illnesses and injuries.
    • Employers must provide records to government representatives as requested.

    OSHA Inspections and Process

    • OSHA inspectors have the right to enter workplaces to conduct inspections without prior notice to the employer. They will have a warrant that allows them to complete the inspection.
    • OSHA inspectors will typically conduct a "walk-around" inspection, during which they will observe workplace conditions, interview employees and review employer records.
    • The inspector can issue a citation, which is a formal notice from OSHA to the employer that a violation of an OSHA standard has been found.
    • If a violation of an OSHA standard is found, the inspector can issue a citation to the employer.

    OSHA Citations

    • In general, an OSHA citation has to be posted at or near the place a violation occurred for 3 working days
    • OSHA citations provide a brief description of the violation, the standard violated, and the proposed penalty.

    OSHA Citation Penalties

    • Employers have the right to contest the citation, the proposed penalty, or both.
    • The penalty is determined by the gravity of the violation, the employer’s history of OSHA violations, the employer’s size, and the employer’s good faith effort to correct the violation, as well as the employer's ability to pay.
    • OSHA can issue citations for "serious," "willful," "repeated," and "failure to abate" violations.

    Adjustment of Penalties for Good Faith

    • OSHA may reduce the proposed penalty by up to 50% if the employer demonstrates that they have made a good faith effort to correct the violation.

    Appeals

    Employee Appeals

    • Employees can appeal OSHA decisions if they believe the agency has failed to protect their safety and health or if unsafe working conditions remain at the workplace.

    Employer Appeals

    • Employers can appeal OSHA decisions if they disagree with the citation or penalty.

    Petition for Modification of Abatement

    • An Employer can petition OSHA to modify an abatement deadline if they can demonstrate that they need more time to correct the violation.

    Notice of Contest

    • Employers who wish to contest an OSHA citation and/or proposed penalty must file a written notice of contest with OSHA within 15 days of the issuance of the citation.

    Review Procedure

    • If an employer or employee appeals an OSHA decision, the case will be reviewed by an OSHA administrative law judge.
    • The judge can affirm or modify the OSHA decision.
    • Either party can appeal the judge's decision to the Occupational Safety and Health Review Commission (OSHRC).

    Hazard Communication Standard (29 CFR 1910.1200)

    Purpose

    • The purpose of the Hazard Communication Standard (HCS) is to ensure that employees are informed about the hazards of chemicals they work with.
    • The HCS ensures this through the use of labels and Safety Data Sheets.
    • Employees must be trained on the chemical hazards present in the workplace and on how to work safely with them.

    Scope and Application

    • The HCS applies to all employers who handle hazardous chemicals in the workplace.
    • The HCS applies to the production, use or storage of hazardous chemicals, as long as there’s a reasonable chance that chemicals might enter the workplace as a result of these activities.
    • The HCS does not apply to hazardous chemicals that are used in a research laboratory if they are produced or used only in that lab and are used in very small quantities.

    Written Hazard Communication Standard

    • All employers who handle hazardous chemicals in the workplace must have a written hazard communication program. It provides instructions for labeling, and safety data sheets.
    • The program must be accessible to employees and must be reviewed periodically to ensure that it is up to date, and applicable.
    • Employers need a record of all workplace hazardous chemicals requiring labels, Safety Data Sheets and training,
    • It is important to note that if a hazardous chemical does not have a formal safety data sheet, the employer must develop one.

    Label and Other Forms of Warning

    • All containers of hazardous chemicals must be labeled with warning information.

    • The DART is a useful tool for tracking the severity of injuries and illnesses. It can help to identify trends in injury and illness severity and can assist companies in the development of safety programs.
    • It is calculated as follows:
      • DART = (Number of days away, restricted, or transferred cases x 200,000) / (Total hours worked by all employees)
    • The number of days away, restricted, or transferred cases is the number of recordable cases that resulted in an employee being away from work, restricted in their work activities, or transferred to another job.

    Calculating Severity Rates

    • A Severity Rate is a measure of the number of days that employees missed work, were restricted in their work activities, or were transferred to another job as a result of a recordable injury or illness.
    • Severity rates are calculated as follows:
      • Severity Rate = (Number of days away, restricted, or transferred cases x 1, 000, 000) / (Total hours worked by all employees)
