Occupational Health and Industrial Hygiene Flashcards

What is the primary goal of occupational health programs?

Answer: To promote health and prevent workplace illnesses and injuries

Occupational health programs are designed to protect the safety, health, and well-being of people engaged in work or employment. Their primary goal is to identify and control workplace hazards, implement preventative measures, and provide health services to minimize the risk of work-related illnesses and injuries. This ensures a safe and healthy working environment for all employees.

Which of the following is a key component of industrial hygiene?

Answer: Controlling exposure to physical, chemical, and biological hazards

Industrial hygiene is the science and art devoted to the anticipation, recognition, evaluation, communication, and control of environmental stressors arising in or from the workplace. A key component involves identifying and mitigating exposure to various physical, chemical, and biological hazards like noise, chemicals, and pathogens. This proactive approach aims to create a safe and healthy work environment.

What is the role of personal protective equipment (PPE)?

Answer: To provide a last line of defense against hazards

Personal Protective Equipment (PPE) includes items like gloves, safety glasses, hard hats, and respirators, worn to minimize exposure to hazards. While engineering and administrative controls are preferred for hazard elimination, PPE serves as the final barrier when other controls are insufficient or impractical. It protects individual workers from residual risks that cannot be otherwise eliminated.

Which agency sets standards for workplace health and safety in the U.S.?

Answer: OSHA

OSHA, the Occupational Safety and Health Administration, is a federal agency of the United States Department of Labor. Established by the Occupational Safety and Health Act of 1970, its mission is to ensure safe and healthful working conditions for workers by setting and enforcing standards and by providing training, outreach, education, and assistance.

What does a health hazard assessment typically include?

Answer: Reviewing health records and workplace exposure levels

A health hazard assessment systematically identifies potential health risks in the workplace. This typically involves analyzing employee health data, such as medical records and reported symptoms, alongside environmental monitoring data to determine exposure levels to various hazards. The goal is to understand the link between workplace conditions and employee health, enabling targeted interventions.

Why is ventilation important in industrial hygiene?

Answer: To reduce concentration of airborne contaminants

Ventilation systems play a crucial role in industrial hygiene by introducing fresh air and removing stale or contaminated air from a workspace. This process effectively dilutes and exhausts airborne pollutants, such as dust, fumes, and chemical vapors, reducing their concentration to safe levels. Proper ventilation is essential for preventing respiratory illnesses and maintaining air quality.

Which of the following is an example of an ergonomic hazard?

Answer: Improper lifting techniques

Ergonomic hazards are workplace conditions that pose a risk of injury to the musculoskeletal system, often due to repetitive movements, awkward postures, or forceful exertions. Improper lifting techniques, which can strain the back and other joints, are a classic example of an ergonomic hazard. Addressing these hazards involves redesigning tasks or providing training on safe practices.

How often should safety training be conducted?

Answer: Periodically and whenever new hazards are introduced

Safety training is not a one-time event but an ongoing process crucial for maintaining a safe workplace. It should be conducted periodically to reinforce knowledge and skills, and critically, whenever new equipment, processes, or hazards are introduced. This ensures that employees are always aware of current risks and proper safety procedures.

Why is biological monitoring used in occupational health?

Answer: To measure the absorption of hazardous substances

Biological monitoring in occupational health involves analyzing biological samples (like blood or urine) from workers to measure the absorption of hazardous substances or their metabolites. This method directly assesses an individual's internal dose, providing a more accurate picture of exposure than environmental monitoring alone. It helps evaluate the effectiveness of control measures and prevent health effects.
