Study Notes
Air Contaminants
- Aerosols: Form of mist made from tiny solid or liquid particles.
- Dusts: Composed of solid organic or inorganic materials.
- Gases: Commonly emitted during welding processes.
- Vapors: Present in environments where solvents are utilized.
Worker Risk and Exposure
- Exposure risk is influenced by both the magnitude and duration of contact with substances, contradicting the notion that these factors do not affect risk.
- The nature and potency of toxic effects, alongside exposure levels, are vital in evaluating the risk posed to workers.
Health Issues
- Carpal Tunnel Syndrome: Result of repetitive motions or repeated shocks over prolonged periods.
- Asbestos-related illnesses: Include malignant lung cancer, mesothelioma, and asbestosis.
- Lead Exposure: Does not cause skin burns, despite leading to other significant health issues.
Work Environment Safety
- Silica Dust: Exists in airborne particles of sand and rock, posing health risks when inhaled.
- Wood Preservatives: May contain carcinogenic chemicals, requiring careful management to prevent exposure.
- Heat Illness Prevention: Employers must provide cool-down breaks, access to cool portable water, and schedule strenuous activities during cooler times.
Hazard Communication
- The Hazard Communications Standard emphasizes thorough classification of health and physical hazards, including chemical mixtures.
- Compliance deadlines included full adherence by June 2015.
- Employers are not mandated by OSHA to classify chemicals.
Safety Data Sheets and Labels
- Mixture Classification: Utilizes information from safety data sheets unless inaccuracies are known by the manufacturer.
- Product Identifier: Essential element found on labels and safety data sheets for hazardous products.
OSHA Requirements
- Written hazard communication programs must acknowledge the availability of the program but do not require specific goals per employee.
- Trade Secrets: Defined as confidential business information that offers a competitive edge.
- Engineering Controls: Referred as the preferred method to reduce or eliminate hazards.
Industrial Hygiene Practices
- Worksite Analysis: Conducted by industrial hygienists to identify exposure risks and workplace hazards.
- Common practices include prohibiting shared drinking cups in work settings to prevent contamination.
Emergency Preparedness
- Emergency preparation programs are established to address hazard control or prevention during emergencies.
- Key safety measures in ionizing radiation exposure include managing time, distance, and shielding effectively.
