Study Notes

Types of Industrial Hazards

Four main types: Chemical, Biological, Physical, and Ergonomic.

Chemical Hazards

Encompass solids, liquids, gases, vapors, and aerosols.

Biological Hazards

Include insects, animals, soil, plants, water, and blood.

Physical Hazards

Comprised of Noise Exposure, Extreme Temperature, Impact or Vibration, and Radiation.

Ergonomic Hazards

Associated with activities like lifting, holding, pushing, walking, and reaching.

Routes of Chemical Entry into the Body

Inhalation: Breathing in dust, mists, fumes, or gases.
Ingestion: Accidentally swallowing through eating or drinking.
Skin and Eyes: Direct contact.
Injection: Through punctures or cuts.

Symptoms of Chemical Exposure

Effects include irritation of eyes, nose, throat, skin, flu-like symptoms, breathing difficulties, fatigue, and loss of coordination.

Controlling Chemical Hazards

The best control method is to eliminate hazards whenever possible.

Administrative Controls for Chemical Hazards

Training, inspections, and proper housekeeping can limit exposure.

Personal Protective Equipment (PPE)

Required when engineering and administrative controls are insufficient.

Systematic Effects of Exposure

Systematic effects imply that the entire body is affected, not just the exposed area.

Effects of Biological Hazards

Range from mild irritations like allergic reactions to severe life-threatening conditions.

Potential Biological Hazards

Plants like poison ivy may be present in yards.
Bugs around trees can pose risks.
Ant hills should be avoided to prevent bites.

Health Effects of Extreme Temperatures

Extreme cold can lead to frostbite and hypothermia.
Extreme heat can cause dizziness, nausea, and rashes after prolonged exposure.

Protection from Extreme Cold

Use heaters, provide warm spaces, and have a buddy system.
Wear layered clothing, gloves, hats, and insulated waterproof boots.

Protection from Extreme Heat

Stay hydrated, take frequent breaks, and use cooling methods like air conditioning and reflective shields.

Noise Exposure

Results from short-term or long-term exposure to loud noises from machinery.
OSHA sets the noise exposure limit at 85 decibels for a maximum of 8 hours.

Effects of Prolonged Noise Exposure

Risks include hearing loss and other negative health impacts.

Protection from Noise Exposure

Use proper ear protection and seek quiet areas during breaks.

Ergonomics

The study of physical tasks and their impact on the body, including the execution of lifting and reaching.

Causes of Ergonomic Hazards

Arise from repetitive tasks, high-speed physical activities, and poorly designed tools.

Hazards of Poor Ergonomics

Can lead to musculoskeletal disorders.

Understanding Musculoskeletal Disorders

Injuries affecting muscles, tendons, ligaments, and joints due to strenuous work tasks.

Examples of Awkward Postures

Activities like reaching above shoulder height, kneeling, and leaning can stress the body.

Localized Pressure Hazards

Includes pressing against hard edges or using body parts inappropriately, like a hand as a hammer.

Administrative Control Example

Weekly housekeeping checklists help minimize hazardous dust exposure.

Biological Hazard Prevention

Refreshing exam room items like a paper line on the table is crucial post-examination.

Awareness of Physical Hazards

Farm workers like Lorena should recognize hazards such as heat, vibration, and noise.

Identifying Biological Hazards

In specific situations, like transporting trash, watch for biological threats like rodents.
